Description

  The present invention relates to a driving support apparatus and a driving support method that perform appropriate driving support according to a driver's movement.

Conventionally, the display content of the in-vehicle device is switched to an image of a place where the driver's blind spot is captured by a camera (for example, a front camera) installed in the vehicle according to a user operation (for example, a button pressing operation). Therefore, a technology for supporting driving has been proposed.
In addition, there is a technology that assists driving by switching to a camera image outside the vehicle captured by a camera installed in the vehicle when the vehicle travels within a predetermined speed range.

As described above, in the conventional technology, unless the special operation (for example, touch operation) different from the driving operation is performed, the display content of the in-vehicle device is not switched to the camera image, and thus the driving attention may be reduced. There is.
Further, when switching the display contents of the in-vehicle device according to the speed of the vehicle, the display contents are switched even in a scene where the driver does not want to refer to the camera video, which is troublesome.

  For example, there is an apparatus disclosed in Patent Document 1 as a conventional technique for providing driving assistance by displaying an image obtained by photographing a blind spot of a driver with a camera. This device estimates and presents an image of a place that can be a blind spot for the driver from images taken by cameras installed inside and outside the vehicle.

Further, as a conventional technique for providing driving assistance without requiring a special operation from a user, for example, there is a driving assistance device disclosed in Patent Document 2.
This device registers driver-specific operation details (for example, route guidance instruction operation to the navigation device) performed for events such as traffic jams. The corresponding operation content is executed.

JP 2010-184534 A JP 2010-18072 A

In the conventional technique represented by Patent Document 1, a blind spot image is presented regardless of whether the driver wants to present a blind spot image. For this reason, a blind spot image that has nothing to do with the traveling of the vehicle is suddenly displayed, and the driver may feel annoyed.
Further, in Patent Document 1, a place where the driver's blind spot can be estimated from the driver's line-of-sight information or the image of the outward camera is used, so that the processing load of the device is large and the device is expensive and has high computing ability. There is a problem.

On the other hand, the conventional technique represented by Patent Document 2 registers an operation executed after an event occurs as an operation corresponding to the event. For this reason, there is a problem that registration processing is not performed unless an operation is performed after an event occurs.
Further, in the apparatus described in Patent Document 2, when the operation of switching the camera image is associated with the event that the vehicle speed is in a certain speed range, the driver does not want to refer to the camera image. However, when the vehicle is in the above speed range, the switching operation to the camera video is executed without permission.

  The present invention has been made to solve the above-described problems, and an object thereof is to obtain a driving support device and a driving support method capable of performing driving support with appropriate contents at an appropriate timing for the driver. To do.

  The driving support device according to the present invention includes a movement information acquisition unit that acquires movement information of a vehicle driver, a vehicle information acquisition unit that acquires vehicle information related to the state of the vehicle, and a movement pattern of the driver to be driven Based on the support condition data in which the content of driving support corresponding to the vehicle state is registered, the content of the driving support corresponding to the movement pattern corresponding to the driver's movement information and the vehicle state indicated by the vehicle information is determined. A control unit, an information presentation unit that presents the content of driving assistance determined by the control unit, and an input unit to which information is input from the outside. In this configuration, in the support condition data, the magnitude of the movement of the driver's movement pattern that should be driving assistance is registered, and the control unit corresponds to the magnitude of the movement specified from the movement information of the driver. Compared with the magnitude of the movement pattern registered in the support condition data, it is determined whether or not the movement of the driver corresponds to the movement pattern based on the comparison result, and input via the input unit. The magnitude of the movement of the driver's movement pattern that should be supported is registered in the assistance condition data.

  According to the present invention, there is an effect that it is possible to perform driving support with appropriate contents at an appropriate timing for the driver.

Hereinafter, in order to describe the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 1 of the present invention. FIG. 2 is a diagram illustrating an example of support condition data according to the first embodiment.
The driving support device shown in FIG. 1 is a device that is mounted on a vehicle and supports driving of a driver, and includes a movement information acquisition unit 1, a vehicle information acquisition unit 2, an information storage unit 3, a control unit 4, and presentation data. An acquisition unit 5 and an information presentation unit 6 are provided.
The movement information acquisition unit 1 is an information acquisition unit that acquires movement information of a vehicle driver. For example, information capable of recognizing the movement of the driver is acquired, such as a driver's image taken by an in-vehicle camera.

The vehicle information acquisition unit 2 is an information acquisition unit that acquires vehicle information related to the state of the vehicle.
For example, through a CAN (Controller Area Network) communication, in addition to turn signal operation, brake operation, accelerator operation, steering wheel operation, shift operation, vehicle speed pulse signal or acceleration information detected by the acceleration sensor is acquired as information related to vehicle speed To do. That is, the vehicle information is information indicating a driving situation determined by the driving behavior of the driver.

The information storage unit 3 is a storage unit that stores calculation data, programs, and various databases. In particular, the movement pattern of the driver to be driven and the state of the vehicle (each vehicle state of the support condition and the support release condition) The support condition data in which the content of the driving support corresponding to is registered is stored. The information storage unit 3 is realized by, for example, a hard disk device included in the driving support device, or an SD card, a USB memory, or the like that can be appropriately read by the control unit 4.
The support condition data may be constructed in an external data server.
In this case, the control unit 4 reads the support condition data as appropriate by accessing the data server through a communication unit (not shown).

Assistance condition data is data that is registered in association with the content of the driving assistance, by patterning the movements that should be driving assistance in the state of a specific vehicle among the actions naturally performed by the driver other than the driving operation. It is.
The support condition data of ID number 001 shown in FIG. 2 indicates that the vehicle state is “less than 10 km / h” (support condition), and the movement pattern of the driver to support driving at this time is “taken out, either left or right” It is an operation of “swinging to”.

  For example, when the vehicle is less than 10 km / h, it is expected that the vehicle is not traveling substantially and is stopped at an intersection or the like. In such a vehicle state, it is expected that the driver performs the above operation when the driver wants to check the blind spot in front of the vehicle while the vehicle is stopped at an intersection with poor visibility. Therefore, “front camera video (left and right)” is registered in the assistance condition data of ID number 001 as the content of driving assistance corresponding to these. As a result, when the driver performs the above operation in the state of the vehicle, the video of the front camera is displayed on a HUD (head-up display) or the like, and the driver can confirm the front from the video of the front camera. Become.

Further, as shown in FIG. 2, in addition to the vehicle state that is a condition for starting driving assistance, the vehicle condition (support releasing condition) for releasing driving assistance is also registered in the assistance condition data.
For example, in the support condition data of ID number 001, the vehicle state “10 km / h or more” is set as the support cancellation condition. After the front camera image is displayed as described above, even if the vehicle starts traveling and becomes “10 km / h or more”, if the front camera image continues to be displayed, it will hinder driving. For this reason, the vehicle state for canceling driving assistance is also registered in the assistance condition data.

The support condition data of ID number 002 shown in FIG. 2 indicates that the vehicle state is “less than 20 km / h” (support condition), and the driver's movement pattern to be supported at this time is “protruding, face down” It is an operation of “facing the direction”.
When the vehicle is less than 20 km / h, the vehicle is slowing down, and for example, it is expected that the vehicle is traveling on a narrow road. In such a vehicle state, it is expected that the driver performs the above operation when it is desired to confirm the downward direction so that the vehicle does not fall into a side groove or the like.
Therefore, “top view video” is registered in the assistance condition data of ID number 002 as the contents of driving assistance corresponding to these. Thus, when the driver performs the above operation in the state of the vehicle, the top view video of the outside camera is displayed on the HUD (head-up display) or the like, and the driver can confirm the downward direction from the top view video. It becomes possible.
Note that if the top view video continues to be displayed even after the vehicle returns to normal driving, the driving will be hindered. Therefore, “20 km / h or more” is registered as a support cancellation condition.

The control unit 4 is a control unit that controls the operation of the internal configuration of the driving support device.
In particular, the control unit 4 determines the vehicle state indicated by the motion information corresponding to the driver's motion information acquired by the motion information acquisition unit 1 and the vehicle information acquired by the vehicle information acquisition unit 2 based on the support condition data. The content of the driving support corresponding to is determined.
In addition, as a functional configuration thereof, a motion determination unit 40, a vehicle state determination unit 41, and a support data output unit 42 are provided.

The movement determination unit 40 is a determination unit that determines which movement pattern in the support condition data corresponds to the driver's movement information acquired by the movement information acquisition unit 1.
For example, an image of the driver's video obtained by the in-vehicle camera acquired by the motion information acquisition unit 1 is subjected to image analysis, and it is determined whether or not the motion pattern obtained by the image analysis corresponds to the motion pattern in the support condition data.

The vehicle state determination unit 41 determines which vehicle state (support condition and support cancellation condition) in the support condition data corresponds to the vehicle state indicated by the vehicle information acquired by the vehicle information acquisition unit 2. It is.
For example, the current speed of the vehicle is detected based on the vehicle speed pulse signal acquired as the vehicle information by the vehicle information acquisition unit 2, and this speed is included in the vehicle speed range (support condition and support cancellation condition) in the support condition data. Determine whether or not.

  Note that the determination processing by the movement determination unit 40 and the vehicle state determination unit 41 is executed as follows, for example. First, when the vehicle state determination unit 41 determines support condition data of the vehicle state corresponding to the vehicle information from the support condition data, the vehicle state determination unit 41 notifies the motion determination unit 40 of the determined support condition data as an execution candidate. The motion determination unit 40 selects data of a motion pattern corresponding to the driver's motion information from the support condition data notified as an execution candidate from the vehicle state determination unit 41, and determines the content of the driving support.

The support data output unit 42 is a driving support execution unit that executes the content of the driving support determined by the motion determination unit 40 and the vehicle state determination unit 41.
For example, the text information of the driving support message registered in the support condition data is output to the information presentation unit 6. Thereby, the information presentation part 6 displays a driving assistance message or outputs it as a voice.

  Further, the support data output unit 42 selects information corresponding to the content of the determined driving support from the information inside and outside the vehicle acquired by the presentation data acquisition unit 5, and the selected information is used as it is or predetermined. May be processed and output to the information presentation unit 6. As the predetermined processing, for example, when the information presentation unit 6 displays the front camera video with the HUD and supports driving, processing for converting the video data captured by the front camera into a format that can be displayed with the HUD is conceivable. As a result, it is possible to provide driving assistance according to the actual situation inside and outside the vehicle.

  Further, the support data output unit 42 may drive the electrical components of the vehicle according to the content of the driving support. For example, in a parking space with a wall on the left side, if you want to park the vehicle by bringing it to the full left side, driving assistance is performed to close the side mirror so that the left side mirror does not touch the wall. That is, the support data output unit 42 instructs the vehicle control device to drive the side mirror opening / closing mechanism, whereby the side mirror is automatically closed as driving assistance.

  The presentation data acquisition unit 5 is a data acquisition unit that acquires information inside and outside the vehicle that can be used for driving support. Information on the inside and outside of the vehicle includes, for example, images (front camera image, top view image, etc.) captured by a camera provided in the vehicle and including the periphery of the vehicle, and obstacles around the vehicle detected by the distance sensor. Information outside the vehicle, such as distance data, and information inside the vehicle, such as a rear seat side image taken by an in-vehicle camera, can be considered.

  The information presenting unit 6 is an information presenting unit that presents the content of driving assistance determined by the control unit 4. For example, when driving support information is displayed on the in-vehicle monitor, the information presenting unit 6 is realized by a display control unit that controls information display on the in-vehicle monitor. In addition, when driving support information is output from the vehicle speaker as sound, the information presentation unit 6 corresponds to a sound output control unit that controls sound output of the vehicle speaker.

  The movement information acquisition unit 1, vehicle information acquisition unit 2, control unit 4 (motion determination unit 40, vehicle state determination unit 41 and support data output unit 42), presentation data acquisition unit 5 and information presentation unit 6 The microcomputer of the information processing device functioning as the driving support device executes a program relating to processing unique to the present invention, thereby realizing the specific means in which hardware and software cooperate.

Next, the operation will be described.
FIG. 3 is a flowchart showing the operation of the driving support apparatus according to the first embodiment.
While the driver is driving the vehicle, the vehicle information acquisition unit 2 acquires vehicle information (step ST1). Here, the vehicle information is information indicating a traveling state of the vehicle.
Next, in the support condition data stored in the information storage unit 3, the vehicle state determination unit 41 includes support condition data corresponding to the vehicle state (running situation) indicated by the vehicle information acquired by the vehicle information acquisition unit 2 ( It is determined whether or not (execution candidate) exists (step ST2).

If there is no execution candidate (step ST2; NO), the process returns to step ST1 and the above-described processing is repeated.
When execution candidate data exists (step ST2; YES), the vehicle state determination unit 41 notifies the motion determination unit 40 of the execution candidate support condition data determined from the support condition data.

Then, the movement information acquisition part 1 acquires a driver | operator's movement information (step ST3).
Based on the driver's movement information acquired by the movement information acquisition unit 1, the movement determination unit 40 supports the action to be supported in the support condition data notified from the vehicle state determination unit 41 as an execution candidate (the driver who should support driving). It is determined whether or not (movement pattern) has been executed (step ST4).
That is, data of a motion pattern corresponding to the driver's motion information is determined from the support condition data of execution candidates corresponding to the current vehicle state.
This determination may be performed while the vehicle corresponds to the vehicle state (running situation) indicated by the vehicle information, but the process returns to step ST1 after a predetermined determination period has elapsed even in the vehicle state. You may do it.

When the support target action is not performed by the driver (step ST4; NO), the process returns to step ST1 and the above-described processing is repeated.
When the support target action is performed (step ST4; YES), the motion determination unit 40 notifies the support data output unit 42 of the content of the driving support in the support condition data of the motion pattern corresponding to the driver's motion information. To do.

The support data output unit 42 outputs the content of the driving support notified from the motion determination unit 40 to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4 as mentioned above (step ST5).
The support data output unit 42 selects the information corresponding to the content of the driving support notified from the motion determination unit 40 from the inside / outside information acquired by the presentation data acquisition unit 5 and selects the selected information. The information may be output to the information presentation unit 6 as it is or after being subjected to predetermined processing.
As a result, the details of the driving assistance are displayed on the in-vehicle monitor or output from the in-vehicle speaker. Further, the driving of vehicle electrical components may be controlled as driving assistance.

Next, the vehicle state determination unit 41 confirms whether or not the vehicle state satisfies the support cancellation condition in the support condition data for which driving support has been executed, based on the vehicle information acquired by the vehicle information acquisition unit 2 (Step S1). ST6). That is, it is confirmed whether or not the current vehicle state (running situation) corresponds to the vehicle state of the support cancellation condition.
When the current vehicle state does not satisfy the support cancellation condition (step ST6; NO), the process returns to step ST5, and the information presentation unit 6 continues to present the details of the driving assistance.
When the current vehicle state satisfies the support cancellation condition (step ST6; YES), the information presentation unit 6 ends the presentation of the content of the driving assistance.

Thus, in the driving assistance apparatus according to the present invention, the operation (action) that the driver naturally executes when driving assistance is required is used as the driving assistance execution standard.
For example, when an obstacle present outside the vehicle obstructs the field of view in the traveling direction of the vehicle, the driver tries to see the area that is obstructed by the obstacle due to a specific action such as moving his face. On the other hand, if the obstacle does not affect the driving even if the field of view is blocked by the obstacle, the driver performs the normal driving without taking the specific action as described above. Such a specific action is common to humans and is not considered to have great individual differences.

  Therefore, in the present invention, the action that is performed when the driver tries to see a place that is difficult to see outside the vehicle is used as an opportunity for driving support. For example, in the above case, when the driver performs a specific action such as moving his / her face, an appropriate image for the driver is displayed by displaying an image of the previous area blocked by the obstacle with the camera outside the vehicle. It is possible to provide driving support with appropriate contents at the timing.

In addition, it is expected that the behavior of the driver who should provide driving assistance varies depending on the skill level of driving. For example, when checking the side of a vehicle, a driver with a low level of skill may turn his face to the side and may be careless ahead. In this case, if a side image is displayed, driving assistance that contributes to safe driving can be performed.
On the other hand, a driver with a high degree of skill uses the side mirror effectively to check the side, so that the driver does not move much and does not need driving assistance that displays a side image.

Therefore, driving assistance may be performed using assistance condition data in which the contents of driving assistance corresponding to the movement pattern of the driver and the state of the vehicle are registered according to the driving skill level of the driver.
In this case, based on the support condition data according to the driving skill level of the driver, the control unit 4 includes the driving pattern corresponding to the driving information of the driver and the driving support content corresponding to the vehicle state indicated by the vehicle information. Is determined.
For example, by setting the driver's driving skill level as initial information in the driving support device, the driving support device selects driving condition data corresponding to the set driving skill level and performs driving support. By doing in this way, the driving assistance according to the driver's driving skill level becomes possible.

As described above, according to the first embodiment, the movement information acquisition unit 1 that acquires the movement information of the driver of the vehicle, the vehicle information acquisition unit 2 that acquires the vehicle information related to the state of the vehicle, and the driving assistance. Corresponding to the movement pattern corresponding to the driver's movement information and the vehicle state indicated by the vehicle information based on the assistance condition data in which the driving pattern corresponding to the driver's movement and the contents of the driving assistance corresponding to the vehicle state are registered The control part 4 which discriminate | determines the content of driving assistance, and the information presentation part 6 which presents the content of driving assistance which the control part 4 discriminate | determined are provided.
With this configuration, driving assistance is executed with specific actions that the driver naturally performs in a predetermined vehicle state as a trigger. For this reason, driving assistance with appropriate contents can be performed at an appropriate timing for the driver.

Further, according to the first embodiment, the present invention includes the presentation data acquisition unit 5 that acquires information on the inside and outside of the vehicle that can be used for driving support, and the control unit 4 includes the inside and outside of the vehicle acquired by the presentation data acquisition unit 5. From the information, information corresponding to the content of the determined driving support is selected as driving support information, and the information presentation unit 6 presents information inside and outside the vehicle selected by the control unit 4.
With this configuration, it is possible to perform driving support according to the actual situation inside and outside the vehicle.

  Further, according to the first embodiment, in the assistance condition data, the contents of the driving assistance corresponding to the movement pattern of the driver and the state of the vehicle are registered according to the driving skill level of the driver. The unit 4 determines the content of the driving support corresponding to the movement pattern corresponding to the driver's movement information and the vehicle state indicated by the vehicle information based on the assistance condition data corresponding to the driving skill level of the driver. By comprising in this way, the driving assistance according to the driver | operator's driving skill level is attained.

Embodiment 2. FIG.
FIG. 4 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 2 of the present invention. In the driving support apparatus shown in FIG. 4, a position information acquisition unit 7 is added to the configuration of the first embodiment, and a control unit in which a history information management unit 43 is added to the functional configuration instead of the control unit 4. 4A is comprised.
The position information acquisition unit 7 is an information acquisition unit that acquires vehicle position information. For example, the position information of the own vehicle is acquired by analyzing GPS radio waves received from a GPS (Global Positioning System) satellite. Further, the position information may be acquired using the output of the gyro and the vehicle speed pulse of the vehicle speed sensor.

  The history information management unit 43 stores, as history information, the content of driving support corresponding to the place where the driving support is performed and the state of the vehicle at that time (each vehicle state corresponding to the support condition and the support cancellation condition). 3 is stored and managed. For example, when history information is stored in the information storage unit 3 every time driving assistance is performed, and a vehicle approaches a place where driving assistance has been performed in the past, the vehicle state (running situation) is the same as that time. Read the details of driving support in the history information.

  In addition, the movement information acquisition unit 1, the vehicle information acquisition unit 2, the control unit 4A (the movement determination unit 40, the vehicle state determination unit 41, the support data output unit 42, and the history information management unit 43), the presentation data acquisition unit 5 and The information presenting unit 6 is realized as a specific means in which hardware and software cooperate by the microcomputer of the information processing apparatus functioning as the driving support apparatus executing a program related to processing unique to the present invention. The

Next, the operation will be described.
FIG. 5 is a flowchart showing the operation of the driving support apparatus according to the second embodiment.
While the driver is driving the vehicle, the position information acquisition unit 7 acquires the position information of the vehicle (step ST1a). The position information acquired by the position information acquisition unit 7 is output to the history information management unit 43 of the control unit 4A.

  The history information management unit 43 searches the history information in the information storage unit 3 based on the vehicle position information acquired by the position information acquisition unit 7, and the current vehicle position is near the place where driving assistance was performed in the past Is determined (step ST2a). For example, by comparing the current vehicle position with the position of a place where driving assistance was performed in the past, whether or not the distance from the place where driving assistance was performed in the past to the current position of the vehicle is within a predetermined distance range Confirm.

When the vehicle position is near the place stored in the history (step ST2a; YES), the vehicle information acquisition unit 2 acquires vehicle information (step ST3a).
Next, the history information management unit 43 uses the vehicle information indicated by the vehicle information acquired by the vehicle information acquisition unit 2 in the past in the history information (history information including the place where the vehicle is currently approaching). It is determined whether it corresponds to a vehicle state (running situation) (step ST4a).
Whether or not it corresponds to the vehicle state (running situation) when assisting in the past is determined by quantifying the past vehicle state and performing statistical processing such as averaging, and determining this processing result as a comparison target. Also good.

If the current vehicle state is not the vehicle state (running situation) when it was supported in the past (step ST4a; NO), the process returns to step ST3a and the above-described processing is repeated.
Further, when the current vehicle state corresponds to the vehicle state (running state) when the vehicle has been supported in the past (step ST4a; YES), the history information management unit 43 outputs the content of the driving support in the history information as support data. Notify the unit 42.

The support data output unit 42 outputs the content of the driving support notified from the history information management unit 43 to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4A as mentioned above (step ST5a).
In this way, for example, when a vehicle approaches a place where driving assistance that presents a front camera image (left and right) is presented once in the past, a specific action by the driver (leaving himself and checking the right direction) Even if the operation is not executed, the front camera image (left and right) is automatically presented when the vehicle has been supported in the past (less than 10 km / h). That is, driving assistance is performed in advance before the driver performs a specific action.

Next, based on the vehicle information acquired by the vehicle information acquisition unit 2, the vehicle state determination unit 41 confirms whether or not the vehicle state satisfies the support cancellation condition in the history information (step ST6a). Here, when the current vehicle state does not satisfy the support cancellation condition (step ST6a; NO), the process returns to step ST5a, and the information presentation unit 6 continues to present the content of the driving assistance.
When the current vehicle state satisfies the support cancellation condition (step ST6a; YES), the information presentation unit 6 ends the presentation of the content of the driving assistance.

On the other hand, when the vehicle position is not near the location stored in the history (step ST2a; NO), the vehicle information acquisition unit 2 acquires vehicle information (step ST7a).
The vehicle condition determination unit 41 includes support condition data (execution candidate) corresponding to the vehicle condition (running situation) indicated by the vehicle information acquired by the vehicle information acquisition unit 2 in the support condition data stored in the information storage unit 3. Is determined (step ST8a).

If there is no execution candidate (step ST8a; NO), the process returns to step ST7a and the above-described processing is repeated.
When execution candidate data exists (step ST8a; YES), the vehicle state determination unit 41 notifies the movement determination unit 40 of the determined execution candidate support condition data.

Then, the movement information acquisition part 1 acquires a driver | operator's movement information (step ST9a).
Based on the driver's movement information acquired by the movement information acquisition unit 1, the movement determination unit 40 supports the action to be supported in the support condition data notified from the vehicle state determination unit 41 as an execution candidate (the driver who should support driving). It is determined whether or not (movement pattern) has been executed (step ST10a).

When the support target action is not performed by the driver (step ST10a; NO), the process returns to step ST7a and the above-described processing is repeated.
When the support target action is performed (step ST10a; YES), the motion determination unit 40 notifies the support data output unit 42 of the content of the driving support in the support condition data of the motion pattern corresponding to the driver's motion information. .

Thereafter, the history information management unit 43 executes the current vehicle position, the vehicle state indicated by the vehicle information (each vehicle state corresponding to the support condition and the support release condition in the support condition data determined as the execution target), and The contents of the driving support are stored in the information storage unit 3 as history information in association with each other (step ST11a).
The support data output unit 42 outputs the content of the driving support notified from the motion determination unit 40 to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4 as mentioned above (step ST12a).

Next, the vehicle state determination unit 41 confirms whether or not the vehicle state satisfies the support cancellation condition in the support condition data for which driving support has been executed, based on the vehicle information acquired by the vehicle information acquisition unit 2 (Step S1). ST13a).
When the current vehicle state does not satisfy the support cancellation condition (step ST13a; NO), the process returns to step ST12a, and the information presentation unit 6 continues to present the content of the driving assistance.
When the current vehicle state satisfies the support cancellation condition (step ST13a; YES), the information presentation unit 6 ends the presentation of the content of the driving assistance.

As described above, according to the second embodiment, the information storage unit 3 that stores, as history information, the location of driving assistance and the content of driving assistance corresponding to the state of the vehicle at that time, and the position of the vehicle A position information acquisition unit 7 for acquiring information, and the control unit 4A is based on the position information of the vehicle acquired by the position information acquisition unit 7, and the vehicle approaches the place where the driving support in the history information is performed. If the vehicle state indicated by the vehicle information corresponds to the vehicle state in the history information, the content of the driving support in the history information is selected, and the information presenting unit 6 selects the control unit 4A. Present the details of driving assistance.
With this configuration, when a vehicle approaches a place where assistance has been provided to the driver in the past and the vehicle is in a vehicle state when assistance has been provided in the past, the driver is advanced before taking a specific action. Driving assistance. As a result, it is possible to provide driving assistance with appropriate content at an appropriate timing for the driver.

Embodiment 3 FIG.
FIG. 6 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 3 of the present invention. The driving support apparatus shown in FIG. 6 has basically the same configuration as that of the second embodiment, but instead of the information storage unit 3, the map DB (database) 30 is added to the storage contents shown in the first and second embodiments. The information storage unit 3A is added, and instead of the control unit 4A, a control unit 4B in which a map information determination unit 44 is added to the functional configuration is provided.

  The map DB 30 is a database in which map information including facility information (for example, latitude and longitude of a facility, type, parking lot information) and road information (for example, road data defining a road width, an intersection, etc.) is registered. Although FIG. 6 shows the case where the map DB 30 is stored in the information storage unit 3A, it may be downloaded from an external map data server.

The map information discriminating unit 44 is a discriminating unit that discriminates a place where the vehicle exists based on the map information acquired from the map DB 30 and the vehicle position information acquired by the position information acquiring unit 7.
The information storage unit 3A also stores map information (for example, latitude / longitude, facility type, road type such as an intersection, feature type such as a stop line), driver movement pattern, and vehicle Support condition data in which the content of driving support corresponding to the state is registered is stored.

  In addition, the motion information acquisition unit 1, the vehicle information acquisition unit 2, the control unit 4B (the motion determination unit 40, the vehicle state determination unit 41, the support data output unit 42, the history information management unit 43, and the map information determination unit 44), presentation The data acquisition unit 5, the information presentation unit 6, and the position information acquisition unit 7 are configured so that the microcomputer of the information processing device functioning as a driving support device executes a program relating to processing unique to the present invention, Is realized as a concrete means of cooperation.

Next, the operation will be described.
First, the map information discriminating unit 44 discriminates a place where the vehicle exists based on the map information acquired from the map DB 30 and the vehicle position information acquired by the position information acquiring unit 7.
That is, the support condition data including the place where the vehicle exists and should be supported is determined as the execution candidate from the support condition data stored in the information storage unit 3A. In addition, as a place where driving assistance should be provided, for example, an intersection or a road with a narrow road width can be considered.
The map information determination unit 44 notifies the vehicle state determination unit 41 of the execution condition support condition data determined from the support condition data.

The vehicle state determination unit 41 includes a support condition corresponding to the vehicle state (running situation) indicated by the vehicle information acquired by the vehicle information acquisition unit 2 in the support condition data notified as an execution candidate from the map information determination unit 44. Determine whether data exists.
When execution candidate data exists, the vehicle state determination unit 41 notifies the motion determination unit 40 of the determined support condition data as an execution candidate.

Based on the driver's movement information acquired by the movement information acquisition unit 1, the movement determination unit 40 supports the action to be supported in the support condition data notified from the vehicle state determination unit 41 as an execution candidate (the driver who should support driving). It is determined whether or not (movement pattern) is executed.
When the support target action is performed, the movement determination unit 40 notifies the support data output unit 42 of the content of the driving support in the support condition data of the movement pattern corresponding to the movement information of the driver.

At this time, as in the second embodiment, the history information management unit 43 performs the current vehicle position (map information), the vehicle state indicated by the vehicle information (the support condition and the support release condition in the support condition data determined as the execution target). And the contents of the driving assistance to be executed may be associated with each other and stored in the information storage unit 3 as history information.
The support data output unit 42 outputs the content of the driving support notified from the motion determination unit 40 to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4 as mentioned above.

Thereafter, the vehicle state determination unit 41 confirms whether or not the vehicle state satisfies the support cancellation condition in the support condition data in which the driving support is executed, based on the vehicle information acquired by the vehicle information acquisition unit 2. At this time, when the current vehicle state satisfies the support cancellation condition, the information presentation unit 6 ends the presentation of the content of the driving assistance.
By doing in this way, the precision which discriminate | determines the place which should drive assistance to a driver | operator can be improved.

  Moreover, even if the control unit 4B presents the content of the driving support requested by the driver when the driver's movement information acquired by the movement information acquiring unit 1 corresponds to a movement pattern that requires driving support. Good. The movement pattern for requesting driving assistance is a specific action other than the driving operation of the driver, and is set in the movement determination unit 40 in advance. For example, an operation of moving the face or line of sight multiple times left and right can be considered.

When it is determined that the driver's movement information is a movement pattern for requesting driving assistance, the movement determination unit 40 determines the content of driving assistance requested by the driver from the assistance condition data.
In this case, the motion determination unit 40 instructs the information presentation unit 6 to inquire about the driving support content requested by the driver. For example, the information presentation unit 6 outputs an inquiry such as “Are you looking for something?” And receives an answer from the driver via an input unit (not shown).
When a search for a nearby facility is requested by the driver, the map information determination unit 44 searches for a nearby facility from the map DB 30 based on the vehicle location information acquired by the location information acquisition unit 7. The facility information of the peripheral facilities as a search result is output to the information presentation unit 6 via the support data output unit 42. Thereby, the information presentation part 6 presents the facility information of a surrounding facility.
In this way, it is possible to perform driving assistance desired by the driver.

Further, the motion determination unit 40 may determine the content of the driving support requested by the driver based on the driver's motion information acquired by the motion information acquisition unit 1.
In this case, the content of driving assistance is set in the motion determination unit 40 in association with a specific action other than the driving operation of the driver.
For example, a case will be described in which driving assistance in which facility information of a facility in the pointing direction is retrieved and presented is associated with the action of the driver pointing out of the vehicle.
The motion determination unit 40 determines the direction instructed by the driver based on the driver motion information acquired by the motion information acquisition unit 1. The determined instruction direction is notified to the map information determination unit 44.
Based on the map information acquired from the map DB 30 and the vehicle position information acquired by the position information acquisition unit 7, the map information determination unit 44 searches for facility information of facilities existing in the direction indicated by the driver. As a result, the information presentation unit 6 presents the facility information retrieved by the map information determination unit 44. For example, the facility information is listed and displayed.
In this way, it is possible to perform driving assistance desired by the driver.

As described above, according to the third embodiment, the position information acquisition unit 7 that acquires vehicle position information is provided, and the control unit 4B acquires the map information acquired from the map DB 30 and the position information acquisition unit 7. Based on the position information of the vehicle, the location where the vehicle is present is determined, and the map information of the place where the driving assistance should be performed, the driver's movement pattern, and the driving assistance contents corresponding to the vehicle state are registered in the assistance condition data registered. Based on the determined location, the movement pattern corresponding to the movement information of the driver, and the content of the driving support corresponding to the vehicle state indicated by the vehicle information are determined.
By comprising in this way, the precision which discriminate | determines the place which should support a driver | operator can be improved.

  Further, according to the third embodiment, when the driver's movement information acquired by the movement information acquisition unit 1 corresponds to a movement pattern that requests driving assistance, the control unit 4B requests driving assistance requested by the driver. Present the contents. With this configuration, it is possible to perform driving assistance desired by the driver.

  Further, according to the third embodiment, the control unit 4B determines the content of the driving support requested by the driver based on the motion information acquired by the motion information acquiring unit 1. By doing in this way, it is possible to perform the driving assistance which a driver desires, without operating and inputting the contents of driving assistance.

Furthermore, according to the third embodiment, the position information acquisition unit 7 that acquires the position information of the vehicle is provided, and the control unit 4B is based on the driver's movement information acquired by the movement information acquisition unit 1. The direction of the vehicle is determined, and the facility information of the facility existing in the direction instructed by the driver is searched based on the map information acquired from the map DB 30 and the vehicle position information acquired by the position information acquisition unit 7. The information presentation unit 6 presents the facility information searched by the control unit 4.
With this configuration, it is possible to perform driving assistance desired by the driver.

Embodiment 4 FIG.
FIG. 7 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 4 of the present invention.
The driving support apparatus shown in FIG. 7 has a communication unit 8 added to the configuration of the second embodiment, and further includes a control unit 4C in which a communication management unit 45 is added to the functional configuration instead of the control unit 4A. Configured. The communication unit 8 is a communication unit that communicates with an external device, and is realized by a hardware module for performing communication with the external device via a communication network.
Further, the external device is, for example, a data server connected to a communication network, and stores the content of driving support corresponding to the location where the driving support is performed and the state of the vehicle at that time as history information. To do.

  The communication management unit 45 is a management unit that manages information transmitted and received between the communication unit 8 and an external device. For example, the history information received from the external device by the communication unit 8 is output to the vehicle state determination unit 41. Further, by outputting the vehicle position information to the communication unit 8, the history information corresponding to the vehicle position is requested to the external device via the communication unit 8.

  In addition, the movement information acquisition unit 1, the vehicle information acquisition unit 2, the control unit 4C (the movement determination unit 40, the vehicle state determination unit 41, the support data output unit 42, the history information management unit 43, and the communication management unit 45), for presentation The data acquisition unit 5, the information presentation unit 6, and the position information acquisition unit 7 are configured such that the microcomputer of the information processing device functioning as a driving support device executes a program related to processing unique to the present invention, Is realized as a concrete means of cooperation.

Next, the operation will be described.
First, the communication management unit 45 communicates a history information request including the current position information and the latest position information transmitted to the external device the last time out of the vehicle position information acquired by the position information acquisition unit 7. The data is transmitted to the external device via the unit 8.
In the external device, when receiving the history information request from the driving support device, based on the current location information of the vehicle and the latest location information of the vehicle received last time, from the history information managed by the own device, The history information including the location corresponding to the vicinity of the current position of the vehicle and not transmitted last time (location where driving support is to be provided) and the content of driving support is selected and returned to the request source.

The communication management unit 45 updates the content of the support condition data stored in the information storage unit 3 using the history information received from the external device via the communication unit 8.
Note that the support condition data update processing by the communication unit 8 and the communication management unit 45 is periodically executed at predetermined time intervals.

  In this way, even if the driver does not actually receive driving assistance, it is possible to receive driving assistance based on the driving assistance information received by other drivers stored in the external device. is there. As a result, even if it is a place where the driver has never been, if it is a place where many other drivers need driving assistance, the same contents as the driving assistance received by these drivers. You can get driving assistance. In other words, before a driver takes a specific action, it becomes possible to perform driving assistance ahead of the place and content of other drivers receiving driving assistance.

Further, driving support may be performed by appropriately receiving history information from an external device.
For example, the history information management unit 43 accesses an external device via the communication unit 8 and searches for history information corresponding to the vehicle position information acquired by the position information acquisition unit 7. It is determined whether or not the vehicle is near the place where driving assistance was performed.
For example, by comparing the current vehicle position with the position of a place where driving assistance was performed in the past, whether or not the distance from the place where driving assistance was performed in the past to the current position of the vehicle is within a predetermined distance range Confirm.

  When the vehicle position is in the vicinity of the location stored in the history, the history information management unit 43 sets the vehicle state indicated by the vehicle information acquired by the vehicle information acquisition unit 2 to the history information (the location where the vehicle is currently approaching). In the history information), it is determined whether or not the vehicle state (running situation) when assisting in the past is satisfied. Here, when the current vehicle state corresponds to the vehicle state (running situation) when the vehicle has been supported in the past, the history information management unit 43 notifies the support data output unit 42 of the content of the driving support in the history information. .

  The support data output unit 42 outputs the content of the driving support notified from the history information management unit 43 to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4C as mentioned above. Even in this way, driving assistance is performed in advance before the driver performs a specific action.

As described above, according to the fourth embodiment, the communication unit 8 communicates with the external device that stores the location of the driving assistance and the content of the driving assistance corresponding to the state of the vehicle at that time as history information. The control unit 4C is approaching the place where the driving support in the history information received from the external device by the communication unit 8 is performed based on the vehicle position information acquired by the position information acquisition unit 7. When the vehicle state indicated by the vehicle information corresponds to the vehicle state in the history information, the driving support content in the history information is selected, and the information presenting unit 6 selects the driving selected by the control unit 4C. Present the details of the support.
By configuring in this way, it is possible to receive driving assistance having the same content at a place where many drivers need assistance even in places where the driver has never been.

Embodiment 5. FIG.
FIG. 8 is a block diagram showing the configuration of the driving support apparatus according to Embodiment 5 of the present invention.
The driving support apparatus shown in FIG. 8 has basically the same configuration as that of the second embodiment, but instead of the input unit 9 and the information storage unit 3, the movement pattern of the driver to be driving supported is large in movement. A control unit having an information storage unit 3B for storing support condition data or history information in association with each other, and having a motion determination unit 40A for determining a driver's movement pattern based on the magnitude of movement, instead of the control unit 4A The unit 4D is provided.

  As shown in FIG. 9, the information storage unit 3 </ b> B performs driving support corresponding to the movement pattern of the driver to be driving supported, the magnitude of the movement, and the state of the vehicle (each vehicle state of the support condition and the support release condition). The support condition data whose contents are registered is stored. Here, the magnitude of the movement is an index value quantified based on the amount of change of the driver (for example, the amount of change of a characteristic part such as face, arm, etc.) and the change time when the driver performs the support target action. It is.

By using the magnitude of movement as a criterion, it is determined that the driver should perform driving support when the driver performs the support target behavior confidently, and if the driver accidentally performs the support target behavior, There is a high possibility that it is determined that driving assistance should not be performed based on the size of the vehicle.
Thereby, the reliability of the start determination of driving assistance can be improved.

Further, the magnitude of movement in the support condition data of the information storage unit 3B may be appropriately set by the user using the input unit 9.
For example, if the driver wants to easily receive driving assistance, set the magnitude of movement of the criterion in the assistance condition data with a small value, and if he does not want to receive much driving assistance, increase the magnitude of movement. Set. In this way, the magnitude of the movement of the support condition data becomes a determination criterion (threshold value) for starting driving support.

The magnitude of the movement of the support target action generally increases in proportion to the poor visibility of the place where the vehicle exists and the driver's anxiety.
Therefore, by setting the magnitude of movement in the support condition data using the input unit 9, for example, the threshold for determining the start of driving support can be changed according to the driving skill level of each driver. it can.

The motion determination unit 40A compares the magnitude of movement in the support condition data stored in the information storage unit 3B with the magnitude of the driver's movement acquired by the movement information acquisition unit 1, and drives based on the comparison result. It is determined whether a person's movement corresponds to a movement pattern.
For example, the magnitude of the movement of the support target action by the driver acquired by the movement information acquisition unit 1 is the magnitude (index value) of the movement pattern corresponding to the support condition data stored in the information storage unit 3B. When exceeding, it determines with a driver | operator's movement being a movement pattern of assistance object action.

The input unit 9 is an input unit for inputting information from the outside.
For example, it includes hardware for input such as operation keys, operation buttons, and a touch panel, and software that outputs an input signal input thereto to the control unit 4D. Moreover, the input part which inputs information by voice recognition may be sufficient.

  In addition, the movement information acquisition unit 1, the vehicle information acquisition unit 2, the control unit 4D (the movement determination unit 40A, the vehicle state determination unit 41, the support data output unit 42, and the history information management unit 43), the presentation data acquisition unit 5, The information presentation unit 6 and the position information acquisition unit 7 are a specific example in which the microcomputer of the information processing device functioning as the driving support device executes a program related to processing unique to the present invention, whereby hardware and software cooperate. As a practical means.

Next, the operation will be described.
FIG. 10 is a flowchart showing the operation of the driving support apparatus according to the fifth embodiment.
In FIG. 10, the processing from step ST1b to step ST3b is the same as the processing from step ST1 to step ST3 in FIG.
When the process of step ST3b is completed, the motion determination unit 40A determines that the driver has executed the support target behavior of the support condition data based on the driver motion information acquired by the motion information acquisition unit 1. Analyzing the person's movement information and indexing the magnitude of the movement. For example, an index value indicating the magnitude of movement is calculated based on the change amount and change time of a characteristic part such as a driver's face and arm.

Next, the movement determination unit 40A compares the magnitude of movement calculated from the movement information of the driver as described above with the magnitude of movement registered in the support condition data, and based on the comparison result, the driver It is determined whether or not the support target action corresponding to the current vehicle state has been performed with a predetermined size (step ST4b). Here, it is determined whether or not the driver has performed the support target action with a magnitude exceeding the magnitude of the movement in the support condition data.
If the driver does not perform the support target action at a predetermined magnitude below the magnitude of the movement in the support condition data (step ST4b; NO), the process returns to step ST1b and the processes from step ST1b to step ST4b are repeated. .

On the other hand, when the driver is performing the support target action at a predetermined size exceeding the magnitude of the movement in the support condition data (step ST4b; YES), the motion determination unit 40A causes the driver to perform the support target action. It judges that it is performing, and notifies the content of the driving assistance registered in the assistance condition data including the assistance target action to the assistance data output unit 42.
The support data output unit 42 outputs the content of the driving support notified from the motion determination unit 40 </ b> A to the information presentation unit 6. Thereby, the information presentation part 6 presents the content of the driving assistance determined by the control part 4D as mentioned above (step ST5b).
The subsequent processing of step ST6b is the same as step ST6 of FIG.

Further, for example, as shown in FIG. 11, the information storage unit 3B may store the movement pattern of the driver to be driven and the magnitude of the movement in the history information.
In this case, the history information management unit 43 compares the magnitude of the movement stored in the history information with the magnitude of the movement for performing driving support set in advance by the driver, and based on the comparison result, the history is recorded. The contents of the driving support registered in the information are notified to the support data output unit 42.
For example, the history information management unit 43 determines that the vehicle is approaching the place where the driving support in the history information is performed based on the position information of the vehicle acquired by the position information acquisition unit 7, and the vehicle information is When the state of the vehicle to be shown corresponds to the state of the vehicle in the history information, the condition of the magnitude of movement in the history information and the magnitude of movement for performing driving support set in advance by the driver via the input unit 9 And compare. At this time, when the magnitude of the movement performed in the past in the history information exceeds the magnitude of the movement for performing the driving assistance set in advance, the history information management unit 43 determines the movement of the driver. Instead, the support data output unit 42 is notified of the details of the driving support in the history information. Thereby, it becomes possible to perform driving assistance ahead of time before the driver takes a specific action.

  Note that the control unit 4D determines that the movement information of the driver corresponds to the support target action (the movement pattern of the driver that should support driving), and the vehicle state indicated by the vehicle information corresponds to the state of the vehicle that should support driving. In addition, regardless of the magnitude of the movement of the driver, the movement pattern, the state of the vehicle, the vehicle position, and the content of driving assistance corresponding to these may be stored in the information storage unit 3B as history information.

  For example, even if the size of the movement is set in advance so that driving assistance is performed only in places where a large movement (supported action) has been performed in the past, You may also want to display driving assistance information for places that have made small movements in the past. In this case, if history information is stored in accordance with the magnitude of the driver's movement, data to be stored as history information may be reduced, which may reduce the reliability of driving support determination.

  Therefore, regardless of the magnitude of the driver's movement, that is, even when driving support is not performed, if the driver performs the support target action and enters the corresponding vehicle state in the support condition data, the current position etc. Save the data it contains as history information. By doing in this way, history information increases, it is possible to improve the reliability of determination of driving support, and it becomes possible to perform proactive support in many places.

Further, the external device shown in the fourth embodiment may store the history pattern information including the movement pattern of the driver to be driven and the magnitude of the movement.
In this case, the history information management unit 43 compares the magnitude of the movement stored in the history information with the magnitude of the movement for performing driving support set in advance by the driver, and based on the comparison result, the history is recorded. The contents of the driving support registered in the information are notified to the support data output unit 42.
For example, the place where the history information management unit 43 provided driving support in the history information received from the external device by the communication unit (for example, the communication unit 8) based on the vehicle position information acquired by the position information acquisition unit 7 When the vehicle state is determined to be approaching and the vehicle state indicated by the vehicle information corresponds to the vehicle state in the history information, the magnitude of movement in the history information and driving via the input unit 9 are performed. The condition of the magnitude of movement for performing driving support set in advance by the person is compared. At this time, when the magnitude of the movement performed in the past in the history information exceeds the magnitude of the movement for performing the driving assistance set in advance, the history information management unit 43 determines the movement of the driver. Instead, the support data output unit 42 is notified of the details of the driving support in the history information. Even in this way, it becomes possible to proactively provide driving assistance before the driver takes a specific action while improving the reliability of the determination as to whether or not the driver has performed the action to be supported. .

  Even in the above-described case, the control unit 4D determines that the movement of the driver corresponds to the action to be supported (the movement pattern of the driver that should support driving), and the vehicle state indicated by the vehicle information changes to the state of the vehicle that should support driving. If applicable, regardless of the magnitude of the driver's movement, the movement pattern, vehicle state, vehicle position, and corresponding driving assistance content are transmitted to the external device by the communication unit 8 and stored as history information. May be. This also increases the history information and can improve the reliability of the driving support determination.

As described above, according to the fifth embodiment, the control unit 4D compares the magnitude of the movement registered in the support condition data with the magnitude of the driver's movement acquired by the movement information acquisition unit 1. Based on the comparison result, it is determined whether or not the driver's movement corresponds to the movement pattern.
By doing in this way, when a driver | operator carries out assistance object action confidently, possibility that a driving assistance will be started becomes high, and the reliability of the start judgment of a driving assistance can be improved.

  Further, according to the fifth embodiment, the input unit 9 to which information is input from the outside is provided, and the control unit 4D is configured to detect the movement pattern of the driver to be driven and input through the input unit 9. Register the size in the support condition data. By doing in this way, the threshold value which judges the start of driving assistance according to the driving skill level for every driver can be changed, for example.

  Further, according to the fifth embodiment, the input unit 9 for inputting information from the outside is provided, and the information storage unit 3B includes the movement pattern of the driver to be driven and the magnitude of the movement in the history information. And the control unit 4D determines that the vehicle is approaching the place where the driving support in the history information is performed based on the position information of the vehicle acquired by the position information acquisition unit 7, and When the vehicle state indicated by the vehicle information corresponds to the vehicle state in the history information, the magnitude of movement in the history information is compared with the magnitude of movement for performing driving support set in advance via the input unit 9 When the magnitude of movement in the history information satisfies the magnitude of movement for performing driving assistance set in advance, the contents of driving assistance in the history information are presented regardless of the movement of the driver. . By configuring in this way, driving assistance before the driver takes a specific action while improving the reliability of determining whether the driver's movement has performed a movement pattern (supported action) It becomes possible to do.

  Further, according to the fifth embodiment, the control unit 4D corresponds to the movement pattern of the driver whose driving information should be supported by the driver, and the vehicle state indicated by the vehicle information is the state of the vehicle that should be driving assistance. In this case, regardless of the magnitude of the movement of the driver, the movement pattern, the state of the vehicle, the vehicle position, and the content of driving support corresponding to these are stored in the information storage unit 3B as history information. With this configuration, the history information is increased, and the reliability of the driving support determination can be improved.

  Further, according to the fifth embodiment, the input unit 9 for inputting information from the outside is provided, and the external device stores the movement pattern of the driver to be driven and the magnitude of the movement in the history information. Then, based on the vehicle position information acquired by the position information acquisition unit 7, the control unit 4D approaches the place where the driving support is performed in the history information received from the external device by the communication unit 8. When the vehicle state indicated by the vehicle information corresponds to the vehicle state in the history information, the magnitude of movement in the history information and driving support set in advance via the input unit 9 are performed. If the magnitude of movement in this history information satisfies the preset magnitude of movement for driving assistance, this history is used regardless of the driver's movement. Luck in information To present the contents of the support. Even in this way, it becomes possible to proactively provide driving assistance before the driver takes a specific action while improving the reliability of the determination as to whether or not the driver has performed the action to be supported. .

  Furthermore, according to the fifth embodiment, the control unit 4D corresponds to the movement pattern of the driver whose driving assistance should be supported, and the vehicle state indicated by the vehicle information is changed to the state of the vehicle to be driving assistance. If applicable, regardless of the magnitude of the driver's movement, the movement pattern, the vehicle state, the vehicle position, and the corresponding driving assistance content are transmitted to the external device by the communication unit 8 and stored as history information. . This also increases the history information and can improve the reliability of the driving support determination.
