JP 2010-144684 A

  In the conventional driving support apparatus as described above, the same teaching content is repeatedly presented until reaching a reference value that can be regarded as having acquired the teaching content. For this reason, there was a problem that the same teaching item repeatedly presented deprived of the opportunity to present other teaching items. In addition, there are cases where the driver's driving is hindered by the presentation of the teaching item and the level of driving operation is lowered. In such a case, the same teaching item is presented unless the reference value is achieved. The burden on the driver was heavy because it continued.

  In view of the above background, an object of the present invention is to provide a driving support device that presents appropriate teaching items.

  The driving support apparatus according to the present invention includes a teaching item storage unit that stores teaching items about driving operations of a vehicle and a message that indicates the teaching contents, and driving operation information that indicates the amount of driving operation and the date and time when the driving operation was performed. A driving operation information acquisition unit to acquire, a driving operation information storage unit to store the driving operation information, a teaching history information storage unit to store teaching history information indicating a teaching item presented to the driver and its presentation date and time, A realization level table storing a driving operation amount and a realization level corresponding to the driving operation amount for each teaching item, reading driving operation information of a predetermined teaching item from the driving operation information storage unit, and storing the teaching history information The teaching item when the teaching history information of the predetermined teaching item is read from the unit and the driving operation is performed by comparing the date and time when the driving operation is performed with the date and time when the teaching item is presented It is determined whether or not it is presented, and the driving operation amount when the teaching item is presented and the driving operation amount when the teaching item is not presented are obtained, and the teaching item is presented with reference to the realization level table The driving operation amount realization level when the teaching item is not presented and the driving operation amount realization level when the teaching item is not presented are obtained, and the driving operation amount realization level when the teaching item is not presented is the predetermined target value. A presentation continuation determination unit that determines to stop presenting a teaching item when it is achieved and to continue presenting a teaching item when the target value has not been reached, and to realize the level of driving operation when the teaching item is presented Is less than or equal to the realization level of the driving operation amount when the teaching item is not presented, even if the realization level of the driving operation amount does not reach the predetermined target value, the teaching item is presented. To cancel A continuation cancellation information storage unit that stores information indicating whether to continue or cancel the presentation for each teaching item based on the determination result of the presentation continuation determination unit, and the continuation cancellation information storage A teaching output unit that selects and outputs a teaching item to be output from teaching items for continuing presentation.

  When the realization level of the driving operation amount when the teaching item is presented in this way is equal to or less than the realization level of the driving operation amount when the teaching item is not presented, the realization level of the driving operation amount is a predetermined target value. Even if it does not reach the point, it is not necessary to present the teaching item when the presentation of the teaching item interferes with driving by adopting a configuration that stops the presentation of the teaching item. If the learning level is the same level and there is no possibility of learning, the teaching item can be stopped and another appropriate teaching item can be presented. Here, the teaching items regarding the driving operation include, for example, the strength of the accelerator operation, the speed of the steady vehicle speed, the strength or timing of the brake operation, the presence / absence or timing of the blinker operation, and the like.

  In the driving support device of the present invention, the presenting continuation determination unit has a predetermined target value for the realization level of the driving operation amount of the teaching item for the teaching item in which the information of the presentation cancellation is stored in the continuation cancellation information storage unit. When it is determined that the target value has not been achieved, the information on the cancellation of presentation of the teaching item stored in the continuation cancellation information storage unit is changed to information on continuation of presentation. Also good.

  As described above, the actual level of the driving operation amount is continuously checked even for the teaching item whose presentation has been canceled once. When the driving operation amount has not reached the target value, the teaching item is again displayed. By presenting, it is possible to support the re-learning of the teaching item whose realization level is reduced.

  In the driving support device of the present invention, the presenting continuation determining unit is configured to provide a teaching item with a realization level of the driving operation amount of the teaching item with respect to the teaching item in which the information about the presentation cancellation is stored in the continuation canceling information storage unit. It is determined whether the driving operation amount is lower than the actual level when the teaching item is presented when the cancellation is determined. If it is determined to be lower, the teaching item stored in the continuous cancellation information storage unit is presented. You may change the information of cancellation to the information of continuation of presentation.

  In this way, when the realization level of the driving operation amount is lower than the realization level of the driving operation amount when the teaching item was previously presented, there is no obstacle to driving even if the teaching item is presented. Since it is possible to improve the driving technique, it is possible to support the re-learning of the teaching item whose realization level has been lowered by presenting the teaching item again.

  The driving support device according to the present invention increases the realization level of the target value when the number or ratio of the teaching items that have achieved the target value reaches a predetermined threshold, and also stores the teaching stored in the continuation stop information storage unit. The information on the cancellation of the presentation of the item may be changed to information on the continuation of presentation.

  When the target value can be achieved for many teaching items as described above, the driving technique of the driver can be improved by increasing the target value and presenting the teaching item.

In the driving support device of the present invention, the presentation continuation determination unit is configured to stop the continuation when a predetermined time has elapsed since the information about the continuation of presentation stored in the continuation cancellation information storage unit is changed to the information about presentation cancellation. The information for stopping the presentation of the teaching item stored in the information storage unit may be changed to information for continuing the presentation.
With this configuration, the operation of the teaching item can be reviewed.

  In the driving support device of the present invention, the teaching item is a teaching item for driving operation according to driving scene, and the driving operation information acquisition unit performs the driving operation amount and driving scene related to the teaching item and the driving operation thereof. Driving operation information indicating the date and time may be acquired and stored in the driving operation information storage unit.

  As described above, the driving operation according to the driving scene can be acquired by using the driving operation for each driving scene as the teaching item. Here, the driving scene is, for example, a traveling state, a road attribute, a traffic flow, a point or an area. For example, in the running state, teaching items for driving operation may be prepared for each state such as starting, overtaking, and turning left. The road attribute is, for example, an expressway, a general road, a street, or the like. The traffic flow is, for example, vacant, congested, or congested. Points and areas are predetermined intersections, curves, gas stations, and the like.

  In the driving support device of the present invention, the teaching item storage unit groups and stores a plurality of teaching items, and the presentation continuation determination unit continues or stops the presentation of all the teaching items included in the group. Based on the number of teaching items for which presentation is to be continued and the number of teaching items for which presentation is to be stopped, it may be determined whether to continue or cancel the presentation of all the teaching items included in the group.

  With this configuration, it is possible to manage whether to continue or stop the presentation for the teaching items in the group.

  The driving support method of the present invention is a method implemented by the above-described driving support device, and the program of the present invention is a program for realizing the driving support method. Such a driving support method and program also have the same effects as the driving support apparatus described above.

  According to the present invention, even when the realization level does not reach the predetermined target value, by adopting a configuration in which the presentation of the teaching item is adopted, the presentation of the teaching item becomes an obstacle to driving. If there is no possibility of learning with the same level of realization, whether or not the teaching item is presented, the presentation of the teaching item can be stopped and another appropriate teaching item can be presented There is.

  Hereinafter, a driving support device according to an embodiment of the present invention will be described with reference to the drawings. Prior to detailed description of the driving support apparatus according to the embodiment, the concept of continuation of presentation of teaching items and determination of cancellation performed by the driving support apparatus will be described.

  FIG. 1 (a) to FIG. 1 (f) are graphs showing the relationship between the target value of the realization level of the driving operation amount and the realization level when the teaching item is presented and when it is not presented. Here, the realization level is a value expressing the driving operation amount as a score of the driving technique, and indicates that the higher the realization level is, the higher the driving operation skill is. The conversion from the driving operation amount to the realization level is performed with reference to the realization level table described later. Each figure of Fig.1 (a)-FIG.1 (f) has shown that the implementation level is so high that it goes to the right side. The position of the target value and the range on the right side of the target value are ranges of the achievement level determined to achieve the target.

  As shown in FIG. 1 (a) and FIG. 1 (b), when the realization level (indicated as “unpresented” in the figure) when the teaching item is not presented is equal to or higher than the target value, the target is achieved. It is considered that the teaching item has been acquired. In this case, the presentation of the teaching item is stopped. However, in the example of FIG. 1B, when the teaching item is presented (denoted as “presentation” in the figure), the level of realization is lower than when the teaching item is not presented. In this case, the teaching item is presented. This is thought to be an obstacle to driving.

  As shown in FIG. 1C to FIG. 1F, when the realization level when the teaching item is not presented does not reach the target value, the teaching item is not learned. Among these, as shown in FIG. 1 (c) and FIG. 1 (d), when the realization level when the teaching item is presented is higher than the realization level when the teaching item is not presented, the teaching item is presented. The effect of doing is seen, and it is thought that there is a prospect of acquisition. In this case, the presentation of the teaching item is continued.

  On the other hand, as shown in FIG. 1E, when the realization level when the teaching item is presented is the same as the realization level when the teaching item is not presented, there is no effect of presenting the teaching item, It is considered that there is no prospect of acquiring the teaching item. Further, as shown in FIG. 1 (f), when the realization level when the teaching item is presented is lower than the realization level when the teaching item is not presented, presenting the teaching item is an obstacle to driving. It is thought that. In the case of FIG.1 (e) and FIG.1 (f), although the said teaching item is not mastered, presentation of a teaching item is stopped. As a result, the opportunity to present other teaching items increases, and the driving technology of the driver can be improved by driving support.

  The determination of continuation / stop of teaching item presentation by the driving support device of the present embodiment has been described above. Below, the structure of the specific apparatus for implement | achieving such judgment is demonstrated.

(First embodiment)
FIG. 2 is a block diagram showing a configuration of the driving support apparatus 1 according to the first embodiment of the present invention. The driving support device 1 is mounted on a vehicle, for example, and is connected to a CAN 30 (Controller Area Network), a navigation device 31, and a display 35. The driving support device 1 is connected to various electronic devices mounted on the vehicle through the CAN 30, and acquires various vehicle signals. The various vehicle signals are, for example, a speed sensor, an accelerator opening, a steering angle of a steering wheel, blinker blinking, lighting of a headlight, and the like. The navigation device 31 includes a navigation ECU 31 that generates route information for realizing a navigation function, and a map database (hereinafter referred to as “map DB”) 33 that stores map information. The navigation device 31 is connected to the GPS 34 and can acquire data on the current position of the vehicle. Information such as vehicle position information (longitude / latitude information), a certain range of road information including the current position, and driving direction information is output to the driving support device 1.

  The driving support apparatus 1 includes a teaching item database (hereinafter referred to as “teaching item DB”) 11 that stores teaching items, and a teaching output unit 10 that outputs teaching contents stored in the teaching item DB 11. The teaching output unit 10 outputs data indicating teaching contents to the display 35, and the display 35 displays the teaching contents. Further, the teaching output unit 10 stores history data presenting teaching contents in a teaching history database (hereinafter referred to as “teaching history DB”) 12.

  FIG. 3 is a diagram illustrating an example of data stored in the teaching item DB 11. The teaching item DB 11 stores teaching item IDs for specifying teaching items and teaching content data corresponding to the teaching item IDs.

  FIG. 4 is a diagram illustrating an example of data stored in the teaching history DB 12. The teaching history DB 12 stores data of presentation time when the teaching item is presented and data of teaching item ID indicating the teaching item presented at the presentation time.

  Returning to FIG. The driving support device 1 includes a continuation stop information storage unit 13 that stores data indicating whether to continue or stop presenting teaching items.

  FIG. 5 is a diagram illustrating an example of data stored in the continuation cancellation information storage unit 13. The continuation cancellation information storage unit 13 stores a teaching item ID for specifying a teaching item and continuation canceling information indicating whether or not to stop presenting the teaching item. Whether the presentation of the teaching item is continued or stopped is determined by the presentation continuation determination unit 14, and the result is reflected in the continuation cancellation information storage unit 13.

  Returning to FIG. The presentation continuation determination unit 14 is connected to a driving operation database (hereinafter referred to as “driving operation DB”) 15 that stores driving operation amount data and the teaching history DB 12 described above, and data stored in both databases. Based on the above, it is determined whether to continue or cancel the presentation of the teaching item.

  FIG. 6 is a diagram illustrating an example of data stored in the driving operation DB 15. The data stored in the driving operation DB 15 is data acquired by the vehicle signal acquisition unit 18 that acquires various vehicle signals through the CAN 30. Here, the vehicle signal acquisition unit 18 corresponds to the “driving operation information acquisition unit” of the present invention. As illustrated in FIG. 6, the driving operation DB 15 stores speed and acceleration data as driving operation amount data, and observation time data when the driving operation amount data is observed. Velocity and acceleration data are calculated by signals from the velocity sensor. In FIG. 6, for convenience of explanation, speed and acceleration data are illustrated as driving operation amount data. However, as the driving operation amount data, in addition to the speed and acceleration data, the accelerator opening degree is also illustrated. Further, data such as steering angle of steering wheel, lighting of blinker, lighting of headlight, and the like can be used.

  The presentation continuation determination unit 14 reads driving operation amount data from the driving operation DB 15 and reads teaching history data from the teaching history DB 12. Then, the observation time of the driving operation amount data is compared with the presentation time of the teaching history data, and the driving operation amount data observed within a predetermined time (for example, 2 minutes) after the teaching item is presented, Judgment is made on the data of the driving operation amount observed when the teaching item is presented, and the driving operation amount observed when the teaching item is not presented on the data of the driving operation amount observed outside the predetermined time. It is determined that the data is.

  Here, although the driving operation performed within a predetermined time after the teaching item is presented is determined as the driving operation at the time of teaching item presentation, it may be determined by the distance instead of the predetermined time. . For example, the driving operation performed within a predetermined distance (for example, 500 m) from the point where the teaching item is presented may be determined as the driving operation at the time of teaching item presentation.

  Subsequently, the presentation continuation determination unit 14 refers to the realization level table 16 that stores the driving operation amount and the realization level in association with each other, and does not present the driving operation amount and the teaching item when the teaching item is presented. Each driving operation amount is converted to an actual level.

FIG. 7 is a diagram illustrating an example of the realization level table 16 having the teaching item ID “T001”. The teaching item ID “T001” is a teaching item related to depression of the accelerator. In this teaching item, vehicle speed and acceleration data, which are driving operation amount data, are associated with the realization level. For example, when the vehicle is accelerated at a speed of 41-50 [km / h] and accelerated at 0.1-1.0 [m / s ² ], the realization level is “10”, 1.1-2. When accelerating at 0.0 [m / s ² ], the driving operation amount can be converted into a score of the realization level, such as “8”. Thereby, the realization level of the driving operation amount can be compared, and the realization level up to the target value can be grasped.

  The presentation continuation determination unit 14 is connected to a target value information storage unit 17 that stores an achievement level score that is a target value. The target value may be a score according to the skill level. The presentation continuation determination unit 14 includes (i) an actual level of the driving operation amount when the teaching item is not presented, (ii) an actualization level of the driving operation amount when the teaching item is presented, and (iii) a target value. Whether to continue or cancel the presentation of the teaching item is determined based on the realization level.

  FIG. 8 is a flowchart illustrating a determination process performed by the presentation continuation determination unit 14. The presentation continuation determination unit 14 first compares the realization level of the driving operation amount when not presented with the realization level of the target value (S10). As a result, when the realization level of the driving operation amount when not presented is equal to or higher than the realization level of the target value (YES in S10), it is determined that the teaching item has been learned and the presentation is stopped (S16).

  When the realization level of the unshown driving operation amount does not reach the realization level of the target value (NO in S10), the presentation continuation determination unit 14 determines the realization level of the driving operation amount when the teaching item is presented. The actual level of the driving operation amount when not presented is compared (S12). As a result, when the realization level of the driving operation amount at the time of presentation is larger than the realization level of the driving operation amount at the time of non-presentation (YES in S12), it is judged that there is a possibility of learning the teaching item and presented. Continue (S14).

  If the realization level of the presented driving operation amount is not higher than the realization level of the driving operation amount when it is not presented (NO in S12), there is no possibility of learning the teaching item, or the presentation of the teaching item is rejected for driving The presentation of the teaching item is stopped (S16).

  FIG. 9 is a diagram illustrating a hardware configuration of the driving support device 1 described above. The driving support apparatus 1 is configured by a computer in which a CPU 40, a RAM 41, a ROM 42, a hard disk 44, a communication unit 45, and a display 35 are connected by a data bus 46. The CPU executes the arithmetic processing according to the program 43 written in the ROM 42, thereby realizing the function of the driving support device 1 described above. Such a program 43 is included in the scope of the present invention.

  Next, operation | movement of the driving assistance apparatus 1 of this Embodiment is demonstrated. The driving support device 1 performs (1) an operation for collecting data of driving operation amounts, (2) an operation for determining continuation / stop of presentation of teaching items, and (3) an operation for outputting teaching items.

[Collecting data of operation volume]
First, (1) operation | movement which collects the data of a driving | operation operation amount is demonstrated. The vehicle signal acquisition unit 18 of the driving support device 1 receives vehicle signals from various devices of the vehicle through the CAN 30. The vehicle signal acquisition unit 18 directly or processes the acquired vehicle signal and stores it in the driving operation DB 15 as driving operation amount data. The vehicle signal acquisition unit 18 stores the date and time when the vehicle signal is acquired as observation date and time data in association with the driving operation amount data. The driving support device 1 accumulates driving operation amount data in the driving operation DB 15 by performing the above operation while the vehicle is traveling. When a plurality of drivers use one vehicle, the driving operation amount data is accumulated for each driver in association with the driver ID.

[Determination of continuation / stop of teaching item presentation]
Next, (2) the operation for determining whether to continue or cancel the presentation of teaching items will be described. The determination of whether to continue or cancel the presentation of teaching items may be made at any time. It may be performed periodically (for example, once a month) or when a predetermined amount of driving operation amount data is accumulated.

  FIG. 10 is a flowchart illustrating an operation in which the driving support device 1 determines whether to continue or cancel the presentation of the teaching item. The presentation continuation determination unit 14 reads the driving operation amount data from the driving operation DB 15 and also reads the teaching history data from the teaching history DB 12 (S20). Then, the observation time of the driving operation amount data is compared with the presentation time of the teaching history data, and the driving operation amount data observed within a predetermined time (for example, 2 minutes) after the teaching item is presented, Judgment is made on the data of the driving operation amount observed when the teaching item is presented, and the driving operation amount observed when the teaching item is not presented on the data of the driving operation amount observed outside the predetermined time. (S22).

  Subsequently, the presentation continuation determination unit 14 refers to the realization level table 16 that stores the driving operation amount and the realization level in association with each other, and does not present the driving operation amount and the teaching item when the teaching item is presented. The driving operation amount at the time is converted to an actual level (S24).

  Next, the presentation continuation determination unit 14 (i) realizes the driving operation amount when the teaching item is not presented, (ii) realizes the driving operation amount when the teaching item is presented, and (iii) ) Based on the target value realization level, it is determined whether to continue or cancel the presentation of the teaching item (S26). This method has already been described with reference to FIG. The presentation continuation determination unit 14 stores the determination result in the continuation cancellation information storage unit 13 (S28).

[Teaching item output]
Next, (3) the operation of outputting teaching items will be described.
FIG. 11 is a flowchart illustrating an operation in which the driving support device 1 outputs a teaching item. The driving assistance device 1 acquires the set guidance route data and the current vehicle position data from the navigation device 31 (S30). The teaching output unit 10 obtains a road link or intersection to travel next from the guidance route and current position data, and extracts teaching items related to the road link or intersection (S32). For example, since it is predicted that the vehicle will stop once at the intersection, teaching items on how to apply the brake and how to step on the accelerator after stopping are extracted. In addition, in the case of making a right or left turn at an intersection, a teaching item regarding the timing of issuing a winker is extracted. If the road link is sharply curved, a teaching item about how to turn the steering wheel is extracted.

  The teaching output unit 10 refers to the continuation cancellation information storage unit 13 and excludes the teaching items that have been canceled from the extracted teaching items (S34). Next, the teaching output unit 10 selects a teaching item to be output from the teaching items for continuing presentation (S36). There are various methods for selecting teaching items. For example, it may be selected randomly, or may be selected from teaching items that have passed a predetermined period since the last presentation, or a teaching in which the difference between the target value and the realization level is a predetermined threshold value or more. It is good also as selecting from an item. The teaching output unit 10 outputs the selected teaching item (S38), and then updates the history data of the presented teaching item (S40).

  The configuration and operation of the driving support apparatus 1 according to the first embodiment have been described above. The driving support device 1 according to the first embodiment has a predetermined realization level when the realization level of the driving operation amount when the teaching item is presented is equal to or less than the realization level when the teaching item is not presented. Even if the target value has not been reached, by adopting a configuration that stops the presentation of the teaching item, the presentation of the teaching item may interfere with driving or the teaching item may be presented. If there is no possibility of learning at the same realization level, the teaching item can be stopped and other appropriate teaching items can be presented.

(Second Embodiment)
FIG. 12 is a diagram illustrating a configuration of the driving support apparatus 2 according to the second embodiment. The basic configuration of the driving support device 2 of the second embodiment is the same as that of the first embodiment, but the teaching items presented by the driving support device 2 of the second embodiment are predetermined. It is different from the first embodiment in that it is a teaching item in the driving scene.

  FIG. 13 is a diagram illustrating an example of data stored in the teaching item DB 11 according to the second embodiment. The teaching item DB 11 stores driving scene data in addition to the teaching item ID and teaching content data. By adding the driving scene data, it is possible to give the driver appropriate advice that matches the driving scene.

  FIG. 14 is a diagram illustrating an example of data stored in the driving operation DB 15 according to the second embodiment. The driving operation DB 15 stores driving scene data in addition to observation time, speed, and acceleration data. FIG. 14 shows an example in which road attribute data such as “narrow street” and “general road” is stored as driving scene data, but various other driving scenes are conceivable. For example, driving scenes such as “when starting”, “turning left and right”, “stop”, and driving scenes such as “congestion” and “crowded” may be included.

  Data stored in the driving operation DB 15 is acquired by the driving operation information acquisition unit. The driving operation information acquisition unit includes a vehicle signal acquisition unit 18, a traveling state determination unit 19, a road attribute acquisition unit 20, and a traffic information acquisition unit 21. The vehicle signal acquisition unit 18 has the same configuration as that described in the first embodiment, and acquires various vehicle signals through the CAN 30. In the present embodiment, the vehicle signal acquisition unit 18 stores the acquired vehicle signal in association with the observation time in the driving operation DB 15 and passes it to the traveling state determination unit 19.

  The traveling state determination unit 19 determines the traveling state of the vehicle based on the vehicle signal acquired from the vehicle signal acquisition unit 18. For example, when the speed gradually increases from the state where the speed is 0 to a steady speed, it is determined that the traveling state has changed from “start” to “steady traveling”, and the determined traveling state data is used as the driving scene. Is stored in the driving operation DB 15.

  The road attribute acquisition unit 20 acquires the road attribute data on which the vehicle is traveling from the navigation device 31 and stores the acquired road attribute data in the driving operation DB 15. For example, the traffic information acquisition unit 21 receives traffic information such as traffic jam information from the center of the VICS (registered trademark) 36 and stores the received traffic information in the driving operation DB 15 as a driving scene.

  Next, operation | movement of the driving assistance apparatus 2 of 2nd Embodiment is demonstrated. The operation of the driving support device 2 of the second embodiment is basically the same as that of the first embodiment, and it is determined whether to continue or cancel the presentation of the teaching item by the same method as in the first embodiment. To do. The driving support device 2 according to the second embodiment is different from the first embodiment in the way of presenting teaching items, and therefore, differences will be described.

  The teaching output unit 10 obtains the guidance route data and the current vehicle position data received from the navigation device 31 and obtains a vehicle signal through the CAN 30 in addition to obtaining the next road link to travel. The traveling state of the vehicle is determined. Then, the teaching item corresponding to the current traveling state of the vehicle is selected, and the teaching item whose presentation has been stopped is excluded from the selected teaching items. When not only the driving state of the vehicle but also the road attribute is used as the driving scene, the road attribute data is acquired from the navigation device 31. When the road situation is used as the driving scene, the VICS (registered trademark) 36 is used. The traffic information is acquired from and the current driving scene is specified. Then, the teaching output unit 10 selects a teaching item corresponding to the identified driving scene. The configuration and operation of the driving support device 2 according to the second embodiment have been described above.

  Similarly to the first embodiment, the driving support device 2 of the second embodiment is configured to display the teaching item when the presentation of the teaching item is obstructing driving or when there is no possibility of learning. This has the effect of stopping the presentation and presenting other appropriate teaching items.

  Further, in the second embodiment, since there are teaching items for each driving scene, it is possible to give appropriate advice to the driver according to the driving scene.

(Third embodiment)
FIG. 15 is a diagram illustrating a configuration of the driving support device 3 according to the third embodiment. The basic configuration of the driving support device 3 of the third embodiment is the same as that of the first embodiment, but the presentation continuation determination unit 14 re-presents the teaching item that has been stopped. A re-presentation determination function 22 for determining whether or not. When the predetermined condition is satisfied, the re-presentation determination function 22 rewrites the information on the cancellation of the presentation of the teaching item that has been stopped to the information on the continuation of the presentation, and enables the re-presentation. Below, the conditions for the presentation continuation determination unit 14 to re-present the presentation cancellation teaching item will be described.

[Condition 1 for re-presentation]
The presentation continuation determination unit 14 also compares the driving operation amount realization level with the target value for the teaching item whose presentation has been stopped. When it is determined that the realization level of the driving operation amount does not reach the target value, or when the state in which the driving operation amount does not reach the target value continues for a predetermined period (or a predetermined number of times), Rewrite the information on the cancellation of presentation to the information on continued presentation.

  FIG. 16A is a diagram showing an example of the progress of the realization level by the above processing. In FIG. 16 (a), the realization level of the driving operation amount when the teaching item is presented is omitted. By presenting the teaching item and causing the driver to learn, the level of realization of the driving operation amount when the teaching item is not presented is improved. Then, when the target value is achieved, the presentation of the teaching item is stopped. In the present embodiment, the realization level of the driving operation amount when not presented and the target value are further compared thereafter. And when the driving level at the time of non-presentation falls below the target value, the teaching item that has been canceled is re-presented. In this way, re-learning can be performed when the realization level of the driving operation amount decreases after the target value is achieved.

[Condition 2 for re-presentation]
The presentation continuation determining unit 14 stops presenting the teaching item because the realization level of the driving operation amount when the teaching item is presented is equal to or less than the realizing level of the driving operation amount when the teaching item is not presented. In such a case, the realization level of the driving operation amount when the teaching item is presented is stored. Then, the presentation continuation determination unit 14 also compares the stored driving operation amount realization level with the current driving operation amount realization level for the teaching item whose presentation has been stopped. Then, when it is determined that the actual level of the driving operation amount does not reach the stored level of the driving operation amount, or when the state continues for a predetermined period (or a predetermined number of times), the teaching item is presented Rewrite the information of cancellation to the information of continuation of presentation.

  FIG. 16B is a diagram showing an example of the progress of the realization level by the above processing. In FIG. 16B, the solid line indicates the transition of the realization level when the teaching item is not presented, and the alternate long and short dash line indicates the transition of the realization level when the teaching item is presented. In this example, by presenting the teaching item and causing the driver to perform learning, the realization level of the driving operation amount when the teaching item is not presented is improved, but the driving operation amount when the teaching item is presented is improved. The level of realization has not improved and is lower than if it was not presented. In this case, since the presentation of the teaching item is considered to hinder driving, the presentation of the teaching item is stopped. In this embodiment, the realization level of the driving operation amount when the teaching item is presented is stored at this time (described as “stored value” in the drawing). Then, the presentation continuation determination unit 14 compares the stored driving operation amount realization level with the current driving operation amount realization level. Then, when the actual level of the driving operation amount decreases and falls below the stored realization level, the teaching item whose presentation has been stopped is re-presented. As a result, the realization level of the driving operation amount is reduced even for the teaching item that is not presented because the presentation of the teaching item hinders driving due to the presentation of the teaching item or the teaching item is not expected. Can be learned when it becomes useful for improving the realization level of the driving operation amount by presenting.

[Condition 3 for re-presentation]
The presentation continuation determination unit 14 counts the number of teaching items that have achieved the target value, and when the number or ratio of the teaching items reaches a predetermined threshold, the target value stored in the target value storage unit is Is updated to a higher realization level, and the information on the cancellation of the presentation of the teaching item that has been stopped is rewritten to the information on the continuation of presentation. With this configuration, the driving skill of the driver can be improved.

[Condition 4 for re-presentation]
The presentation continuation determination unit 14 stores the date and time when the presentation cancellation information stored in the continuation cancellation information storage unit 13 is updated. Then, the presentation continuation determination unit 14 rewrites the information on the cancellation of the presentation of the teaching item whose presentation has been canceled to the information on the continuation of presentation when a predetermined period has elapsed from the date and time as the presentation cancellation. With this configuration, the operation of the teaching item can be reviewed.

  The driving support device 3 according to the third embodiment described above has been described with respect to the driving support device 3 according to the first embodiment, in which the re-presentation determination function 22 is provided, but the second embodiment is described. It is of course possible to provide the re-presentation determination function 22 in the driving support device 2 of FIG.

(Fourth embodiment)
Next, the driving assistance apparatus 4 of 4th Embodiment is demonstrated. The basic configuration of the driving support device 4 of the fourth embodiment is the same as that of the second embodiment, but the driving support device 4 of the fourth embodiment groups teaching items. The point is different.

  FIG. 17 is a diagram illustrating an example of data stored in the teaching item DB 11 according to the fourth embodiment. In the fourth embodiment, teaching items are grouped for each type of driving scene. For each teaching item, the process of comparing the realization level of the driving operation amount when the teaching item is not presented and the realization level of the target value is the same as in the second embodiment.

  The driving support device 4 of the fourth embodiment counts the number of teaching items for which the realization level of the driving operation amount when the teaching item is not presented for each group is equal to or higher than the realization level of the target value, When the number of teaching items exceeds a predetermined threshold or when the ratio to the total number of teaching items in the group exceeds a predetermined threshold, presentation of teaching items for the entire group is stopped.

  In the fourth embodiment, it is possible to manage whether to continue or stop the presentation for the teaching items in the group. In this embodiment, the example in which the teaching items are grouped in the driving support device 2 of the second embodiment has been described. However, in the driving support device 1 of the first embodiment, the teaching items are grouped. Of course, it is also possible. In this case, for example, grouping can be performed according to the type of the vehicle device that has performed the driving operation.

  The driving support device of the present invention has been described in detail with reference to the embodiment, but the driving support device of the present invention is not limited to the above-described embodiment.

  In the above-described embodiment, the display unit 35 is described as an example of the teaching item output unit. However, the output unit may be a speaker. Accordingly, the driver can receive the teaching item without taking his eyes from the front.

  Although not particularly mentioned in the above-described embodiment, the data of the driving operation DB 15 and the teaching history DB 12 may be stored for a certain period, and may be deleted after a certain period has elapsed. Since the driving technology of the driver changes with time, the value of the old data is reduced, but this configuration can prevent the storage area of the computer from being compressed by such low-value data.

  The conversion from the driving operation amount to the realization level can be performed by changing the parameter used for each teaching item. For example, in the above-described embodiment, an example in which vehicle speed data at each time is used has been described. However, for example, an average value or a maximum value of acceleration from the start to the end of the driving operation can be used.

  In the driving support device, the learning state of each teaching item may be displayed or printed. Alternatively, the driving support device and a personal computer may be connected wirelessly or the like so that the learning state on the personal computer screen can be confirmed. Thus, the driver can grasp the learning state by showing the learning state to the driver.

  The present invention presents the teaching item when the presentation of the teaching item is obstructing the driving, or when the teaching item is the same level of realization and is not expected to be learned. This has the effect of stopping and presenting other appropriate teaching items, and is useful as a driving support device or the like that improves the driving skill of the driver in the vehicle.
