By the way, drivers often drive the same automobile that they personally own on a daily basis. On the other hand, in recent years, opportunities to use vehicles in the form of car sharing have been increasing. Therefore, each driver selectively uses various types of vehicles that he or she does not own each time to drive.

When using various types of cars for car sharing, drivers can adjust the seat position, height, posture, etc. to suit their preferences before driving, depending on the unique characteristics of the car being used. It must be adjusted each time. Therefore, the driver may feel troubled by the increased number of operations required before starting to drive.

For example, when employing the technique disclosed in Patent Document 1, it is possible to automatically adjust the posture of the seat based on the physique and posture of the seated person. However, the posture that is automatically adjusted according to the physique and posture of the seated person is not necessarily appropriate for each driver. That is, a posture that is generally considered appropriate may be different from a posture that is considered appropriate according to each driver's preference.

Furthermore, differences in vehicle-specific characteristics such as differences in body size, overall shape of the vehicle (wagon, sedan, sports type, etc.), and height from the ground to the floor of the vehicle interior are also considered. , which is likely to influence the driving posture that suits each driver's preference.

For this reason, in cases such as car sharing, each driver must adjust the posture of his or her seat to suit his or her preference each time before starting to drive, resulting in cumbersome operations. Further, for companies operating car sharing services, it becomes necessary to install expensive sensors to detect the physiques and postures of occupants in all the vehicles they own, which incurs a large amount of installation cost.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable the driver to adjust his or her own vehicle even when the type of vehicle he or she drives changes without requiring the driver to perform troublesome adjustment operations each time. To provide a seat adjustment device that can be adjusted to suit the user's preference.

The above object according to the present invention is achieved by the following configuration.

a seat information acquisition unit that acquires seat information representing the state of the seat set when the driver takes a seat in the first vehicle;
a vehicle information acquisition unit that acquires vehicle information representing unique characteristics for each type of vehicle, including at least the size of the first vehicle;
a transmitting unit that transmits the acquired seat information and the vehicle information to the driver's mobile terminal;
When the driver gets into the second vehicle, the seat information and the vehicle information are acquired from the mobile terminal, and the differences between the vehicle characteristics of the first vehicle and the vehicle characteristics of the second vehicle are reflected. an adjustment control unit that automatically adjusts the seat condition of the second vehicle based on the seat information;
A seat adjustment device comprising:

According to the seat adjustment device of the present invention, when the size or type of the vehicle that the same driver intends to drive changes, the driver can manually adjust the seat according to his/her preference each time before driving. Even if you don't have one, you can automatically adjust the seat to suit your preferences. Therefore, troublesome adjustment operations associated with switching the vehicle to be used can be omitted.

The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the mode for carrying out the invention (hereinafter referred to as "embodiment") described below with reference to the accompanying drawings. .

FIG. 2 is a schematic diagram showing an example of the configuration of a vehicle management table. FIG. 3 is a block diagram showing the main functions on the vehicle when two vehicles are used sequentially. FIG. 4 is a flowchart showing an example of the operation of the seat adjustment device. FIG. 5 is a flowchart showing a modification of the seat adjustment device.

Specific embodiments of the present invention will be described below with reference to each figure.

FIG. 1 is a block diagram showing a configuration example of a seat adjustment device 100 according to an embodiment of the present invention.

The vehicle 10 shown in FIG. 1 includes a driver seat 11, a seat adjustment mechanism 12, a seat adjustment ECU (electronic control unit) 13, a sensor 14, an operation section 15, a storage section 16, as equipment related to seat adjustment. and a communication section 17.

A driver seat 11 in a position where a driver is seated has a movable structure and is connected to a seat adjustment mechanism 12. The posture of the driver's seat 11 can be adjusted by, for example, moving the entire seat back and forth, changing the height of the seat cushion from the floor, and changing the inclination angle of the seat back.

The seat adjustment mechanism 12 includes a plurality of electric motors, and by driving each electric motor, the position, height, posture, etc. of each movable part of the driver's seat 11 can be adjusted. By adjusting the driver seat 11, the driver's body posture during driving can be adjusted to a posture suitable for driving or a posture desired by the driver.

The seat adjustment ECU 13 is composed of an electronic circuit mainly including a microcomputer, and controls the drive of each electric motor of the seat adjustment mechanism 12 to adjust the posture (including position, height, etc.) of the driver's seat 11. It has the function to do.

The sensor 14 detects whether each movable part of the seat adjustment mechanism 12 is at a predetermined reference position, and sends signals representing the actual state of the driver seat 11, such as its position, height, and other postures. Can be output.

The operation unit 15 includes a plurality of switches that can be used to adjust the state of the driver's seat 11 through manual operation by the driver, and a display that can display the state of the driver's seat 11 and the like.

The storage unit 16 is configured by, for example, a nonvolatile memory, and holds vehicle type information representing the type of vehicle 10 in which the seat adjustment device 100 is mounted, and vehicle parameters. Here, the vehicle type information represents the manufacturer name, vehicle type name, and vehicle type (classification such as wagon, sedan, sports type, etc.) of the vehicle. In addition, vehicle parameters are numerical values that reflect the effects of, for example, the size of the vehicle body, the height from the ground to the floor of the vehicle interior, and the distance from the driver's seat to the tip of the vehicle body. It may also consist of numbers. Therefore, vehicle parameters have independent values for each vehicle manufacturer and vehicle type.

The communication unit 17 can connect and communicate with a predetermined smart device 20 using wired communication or wireless communication compatible with the IEEE 802.11 standard, for example.

The seat adjustment device 100 of this embodiment is capable of automatically adjusting the seat state to be appropriate for each user by using the smart device 20 owned by each user when each user attempts to drive various types of vehicles. I can do it.

As a typical example of the smart device 20, a mobile terminal such as a smart phone can be used. By incorporating dedicated application software (app) necessary for using the seat adjustment device 100 into a general smartphone, this can be used as a smart device 20.

When using the seat adjustment device 100, a vehicle management table T01 is prepared on the smart device 20. This vehicle management table T01 includes data that associates information representing the user's individual seat condition preferences with the type of vehicle. Data on the vehicle management table T01 is added sequentially as necessary.

The seat adjustment ECU 13 of this embodiment uses the contents of the vehicle management table T01 on the smart device 20 to adjust the seat to suit the individual driver's preference even when each driver drives a different vehicle model. The seat position, height, posture, etc. can be automatically adjusted to reproduce the actual situation.

Note that the data of the vehicle management table T01 may be held and managed on a predetermined server on the Internet via the smart device 20.

FIG. 2 is a schematic diagram showing an example of the configuration of the vehicle management table T01.
In the example shown in FIG. 2, the vehicle management table T01 holds vehicle manufacturer classification MID, vehicle type classification VT, vehicle parameters VP, and user's individual seat information UP in a mutually associated manner.

Furthermore, in the example of FIG. 2, information on a plurality of vehicle manufacturers MA, MB, and MC is each registered in the vehicle management table T01.

Further, information on each of nine vehicle type classifications VT01, VT02, VT03, VT11, VT12, VT13, VT21, VT22, and VT23 is registered in the vehicle management table T01.

Further, information on each of nine types of vehicle parameters VP01, VP02, VP03, VP11, VP12, VP13, VP21, VP22, and VP23 is registered in the vehicle management table T01. Each of the vehicle parameters VP01 to VP32 is influenced by the size of the vehicle body, the distance from the driver's seat to the tip of the vehicle body, the height from the ground to the floor surface of the vehicle interior, etc., which represent the characteristics of the corresponding vehicle type. This is a reflected value.

Furthermore, nine types of seat information UP001 to UP009 are registered as the user's individual seat information UP, each associated with a different vehicle type. These seat information UP001 to UP009 each represent the state of the seat position, height, posture, etc. that suits the preferences of a specific user who owns the corresponding smart device 20 in the corresponding vehicle.

Since each seat information UP001 to UP009 reflects the preferences of a specific individual, in the initial state when each user starts using the seat adjustment device 100, no appropriate data exists at all. However, regardless of the type of vehicle used, if the same user continues to use the seat adjustment device 100, a large number of seat information UP suitable for each type of vehicle can be registered and maintained in the vehicle management table T01.

<Main functions of the seat adjustment device>
FIG. 3 is a block diagram showing the main functions on the vehicle when the two vehicles 10A and 10B are sequentially used. The manual adjustment functions 31A, 31B, the communication/display functions 32A, 32B, and the automatic adjustment functions 33A, 33B in FIG. 3 are all functions realized by the control of the seat adjustment ECU 13.

When a specific user who owns the smart device 20 uses the seat adjustment device 100 for the first time, data such as a seat posture tailored to the characteristics of the individual (self) does not exist on the vehicle management table T01.

Therefore, when the user gets into the vehicle 10A used as a driver at this time, the automatic adjustment function 33A indicated by the broken line frame does not operate. In this case, the user uses the manual adjustment function 31A to manually adjust the posture and the like of the driver's seat 11 according to his/her preference.

That is, by the user operating a predetermined switch on the operation unit 15 and giving an instruction to the seat adjustment ECU 13, the posture etc. of the driver's seat 11 is changed in a predetermined direction only while the switch is being operated. It can be tailored to the user's own preferences.

The communication/display function 32A digitizes information on the amount of adjustment, such as the posture of the driver seat 11 adjusted by the user using the manual adjustment function 31A, and displays it on the display of the operation unit 15. Send to device 20. The information transmitted at this time can also include vehicle type information and vehicle parameters held in the storage section 16.

The smart device 20 can receive information such as vehicle type information, vehicle parameters, and the posture of the driver's seat 11 transmitted from the communication/display function 32A of the vehicle 10A, and register it in the vehicle management table T01.

When a specific user who owns the smart device 20 uses the vehicle 10A and then uses another vehicle 10B, the data exists in the vehicle management table T01 of the smart device 20, so this data is used. can do.

That is, the communication/display function 32B on the vehicle 10B acquires the data of the vehicle management table T01 from the smart device 20. Further, according to the data acquired by the communication/display function 32B from the smart device 20, the automatic adjustment function 33B automatically adjusts the posture etc. of the driver's seat 11 to reproduce the seat condition that suits the driver's preference. do.

If the seat condition matching the driver's preference can be completely reproduced only by the automatic adjustment of the automatic adjustment function 33B, the manual adjustment function 31B shown by the broken line frame on the vehicle 10B is not necessary. However, the user can also make fine adjustments to the seat posture using the manual adjustment function 31B. Data representing the details of this fine adjustment can be transmitted from the communication/display function 32B to the smart device 20 together with the vehicle type information, and can be additionally registered in the vehicle management table T01.

<Operation of seat adjustment device>
FIG. 4 is a flowchart showing an example of the operation of the seat adjustment device 100. This operation is mainly realized by control of the seat adjustment ECU 13. The operation of FIG. 4 will be explained below.

The seat adjustment ECU 13 communicates with the smart device 20 via the communication unit 17, and there is a vehicle management table T01 containing personal information necessary for adjusting the posture, etc. of the driver seat 11 of the own vehicle. It is determined in S01 whether or not.

If the vehicle management table T01 exists on the smart device 20, the seat adjustment ECU 13 receives the contents of the vehicle management table T01 from the smart device 20 in S02 and acquires necessary information.

Note that the timing at which the seat adjustment ECU 13 actually acquires the contents of the vehicle management table T01 from the smart device 20 is assumed to be, for example, when the engine of the vehicle is started or when the doors of the vehicle are unlocked.

Based on the contents of the vehicle management table T01 received in S02, the seat adjustment ECU 13 performs automatic posture adjustment of the driver seat 11 necessary to reproduce the driver's preferred driving posture in the host vehicle. This corresponds to the automatic adjustment function 33B shown in FIG.

In fact, when using vehicles of the same model, if at least one seat information UP is registered in the vehicle management table T01, the driver's preferred driving posture is determined in S03 based on this seat information UP. Can be reproduced.

Furthermore, even if the same user uses different vehicle models in turn, if multiple vehicle parameters VP and at least one seat information UP that differ for each vehicle model are registered in the vehicle management table T01, this seat information UP Based on this, the driver's preferred driving posture can be reproduced in S03.

For example, if a relational expression expressing the relationship between vehicle parameter VP and seat information UP or an equivalent conversion table is registered in advance, the difference in vehicle parameter VP for each vehicle type and one registered seat Based on the information UP, estimates of the amount of adjustment for the appropriate seat position, height, posture, etc. for each vehicle type are calculated, and the appropriate seat condition can be automatically reproduced in S03.

On the other hand, if the vehicle management table T01 does not exist on the smart device 20, the seat adjustment ECU 13 proceeds to the processing from S01 to S04. Then, the presence or absence of a posture adjustment instruction by the driver by operating a switch on the operation unit 15 is monitored. When the seat adjustment ECU 13 detects a manual posture adjustment instruction from the driver, the process proceeds from S04 to S05. Then, while a manual posture adjustment instruction is given, the electric motor of the seat adjustment mechanism 12 is driven to gradually change the position, height, posture, etc. of the driver's seat 11. When this adjustment is completed, the seat adjustment ECU 13 digitizes the current position, height, posture, etc. of the driver seat 11 detected by the sensor 14 and displays it on the display of the operation unit 15 (S05).

Furthermore, the seat adjustment ECU 13 transmits information such as the posture of the driver seat 11 detected in S05, and the vehicle type information and vehicle parameters VP held in the storage unit 16 to the smart device 20 via the communication unit 17. (S06).

<Modified example of the operation of the seat adjustment device>
FIG. 5 is a flowchart showing a modification of the seat adjustment device 100. This operation is mainly realized by control of the seat adjustment ECU 13. The operation of FIG. 5 will be explained below.

The seat adjustment ECU 13 acquires vehicle type information representing the vehicle type of the host vehicle and vehicle parameters VP of the host vehicle from the storage unit 16 in S11.

The seat adjustment ECU 13 communicates with the smart device 20 via the communication unit 17, and determines in S12 whether seat information UP of the vehicle type that matches the vehicle type information acquired in S11 exists on the vehicle management table T01. Identify with.

If the seat information UP whose vehicle type matches that of the own vehicle already exists on the vehicle management table T01, the seat adjustment ECU 13 proceeds to the processing from S12 to S13. Then, the corresponding seat information UP is acquired from the vehicle management table T01 of the smart device 20, and the seat adjustment ECU 13 automatically adjusts the position, height, posture, etc. of the driver seat 11 according to this seat information UP, and The driving posture is reproduced according to the user's preference (S14).

On the other hand, if the seat information UP whose vehicle type matches that of the own vehicle does not exist on the vehicle management table T01, the seat adjustment ECU 13 proceeds to the processing from S12 to S15. Then, one or more seat information UP for each vehicle type is acquired from the vehicle management table T01 of the smart device 20.

The seat adjustment ECU 13 automatically generates seat information UP in S16 that is suitable for the vehicle type of the own vehicle and suits the driver's preference based on the plurality of seat information UP acquired in S15, and adjusts the seat according to this seat information UP. The ECU 13 automatically adjusts the position, height, posture, etc. of the driver's seat 11 to reproduce a driving posture that matches the driver's preference (S14).

For example, if the two seat information UP001 and UP002 corresponding to the two vehicle classifications VT01 and VT02 in FIG. 2 are registered in the vehicle management table T01, even if the vehicle is in a vehicle classification other than VT01 and VT02. , it is possible to reproduce the desired posture using the seat information UP001 and UP002. For example, by adopting the average value of the two seat information UP001 and UP002 and setting it as the new seat information UP, even in the case of a car model that the driver has not driven in the past, there is a large difference in the driver's preferred posture. You can reproduce the posture without any deviation.

In addition, if the vehicle parameter VPx of the host vehicle exists but the seat information UPx does not exist, the seat information UP001 of the vehicle type of the vehicle model that is closer to the vehicle parameter VPx of the host vehicle among the two vehicle parameters VP01 and VP02 is used instead of the average. Alternatively, UP002 may be employed as the seat information UPx.

Furthermore, even if the vehicle parameter VPx of the own vehicle does not exist, if the vehicle type VTx of the own vehicle is known, the assignment is made to the vehicle type that is closer to the own vehicle's vehicle type VTx of the two vehicle classifications VT01 and VT02. It is also possible to employ the seat information UP001 or UP002 as the seat information UPx.

For example, if the other vehicle's vehicle parameter VP01 and seat information UP001 have already been registered, the own vehicle's vehicle parameter VP02 is known, and the own vehicle's seat information UP002 is unknown, temporarily Seat information UP002 can be determined.

For example, if the vehicle parameter VP02 is in a state indicating that the vehicle body is larger than the vehicle parameter VP01, the result of fine-tuning the value of the seat information UP001 in a direction that increases the driver's driving posture is provisionally adjusted. The seat information is determined to be UP002.

Conversely, if the vehicle parameter VP02 is in a state indicating that the vehicle body is smaller than the vehicle parameter VP01, the result of fine-tuning the value of the seat information UP001 in a direction that reduces the amount of room in the driver's driving posture is provisionally adjusted. The seat information is determined to be UP002.

For example, if the seat information UP001 for a standard sedan type vehicle is registered and the seat information UPx for the own vehicle is unregistered, and the classification VT of the own vehicle is a sports type, the seat information UP001 is registered. Based on the value, the value of the seat information UP001 is adjusted in a direction in which the height of the seat is slightly lowered, and the result can be adopted as the provisional seat information UPx.

Note that the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

For example, the vehicle management table T01 shown in FIG. 2 is assumed to hold data representing a combination of vehicle manufacturer classification MID, vehicle type classification VT, vehicle parameters VP, and seat information UP for each vehicle. Only the combination data of vehicle parameters VP and seat information UP may be registered. Alternatively, only the data of the combination of vehicle type classification VT and seat information UP may be registered.

Furthermore, although the seat adjustment device 100 shown in FIG. can also be obtained as needed. For example, by searching a database on the Internet for various images based on the characteristics of an image of the exterior of the vehicle 10 taken using the camera of the smart device 20, the model of the target vehicle can be identified. Further, if the vehicle type is known, detailed specification information of the corresponding vehicle can be obtained, so it becomes possible to specify the value of the vehicle parameter VP from this information.

Furthermore, although the above-described embodiment shows a case in which only the state of the driver's seat 11 is adjusted, the angle of the rear-view mirror, the angle of the side mirror, etc. It is also possible to adjust automatically. Furthermore, if the same family members always ride together with the driver in the vehicle, it may be possible to adjust the postures of the driver's seat 11 and the passenger seat in the same way.

As described above, when using the seat adjustment device 100 of this embodiment, even when the user changes and drives various types of vehicles each time due to car sharing, for example, the driver seat 11 can be adjusted. There is no need to manually adjust the position, height, posture, etc. each time to suit the driver's individual preferences. In other words, by registering and managing the results of at least one adjustment made by the driver in the vehicle management table T01, the driver can adjust the seat condition to suit his or her preferences even if the type of vehicle changes. It can be automatically adjusted to the correct state.

As a result, the driver can always drive each vehicle in the same position without performing any special adjustment operations, thereby reducing driver fatigue caused by driving. Moreover, effects that lead to accident prevention can also be obtained.
