  However, in the conventional apparatus, the case where the user uses a plurality of vehicles having different vehicle types is not sufficiently considered. In other words, device setting information in a certain vehicle type cannot be used as it is as device setting information in another vehicle type.

  As a specific example, consider the setting of the sheet position. In the vehicle type A, the seat position can be set to 100 levels, and the set value is any one of 1 to 100. Further, in the vehicle type B, the seat position can be set in 256 stages, and the set value is any one of 1 to 256. Then, the setting value 50 of the seat position in the vehicle type A and the setting value 50 of the seat position in the vehicle type B are not the same. Therefore, the seat position in the vehicle type B cannot be set to the position intended by the user by simply using the set value of the seat position in the vehicle type A as it is. In particular, with respect to devices that are set based on the physical characteristics of the user, such as the seat position and the mirror angle, it is important that the setting is surely set to the setting intended by the user.

  In view of the above-described problems, the present invention is capable of reliably setting a device that is set based on the physical characteristics of the user to a setting intended by the user even when the vehicle types are different. The purpose is to provide an adjustment system.

  In order to achieve the above object, in the in-vehicle device adjustment system according to claim 1, the setting information of the device that is set based on the physical characteristics of the user mounted on the vehicle, the vehicle type information of the vehicle, the user The vehicle is provided with a transmission means for transmitting the identification information to the data center and a setting change means for changing the setting of the device according to the setting information transmitted from the data center. From the database means stored as the vehicle type information transmitted from the transmission means, the structure information of the vehicle type is retrieved from the database means, and based on this, the setting information of the equipment transmitted from the transmission means is referenced to a predetermined coordinate axis. The position information conversion means for converting the position information into the position information and the device position information converted by the position information conversion means The storage means for storing in association with the transmitted identification information, and the vehicle type information and identification information transmitted from the transmission means, the structure information of the vehicle type is retrieved from the database means, and the position stored in association with the identification information It comprises a setting information transmitting means for reading information from the storage means, converting the read position information into setting information based on the retrieved structure information, and transmitting the setting information to the setting changing means.

  As described above, in the in-vehicle device adjustment system according to claim 1, the data center transmits the device setting information transmitted from the vehicle and set based on the physical characteristics of the user based on the structure information of the vehicle type. , Converted into position information based on a predetermined coordinate axis and stored. The stored position information is converted from the vehicle type information transmitted from the transmission unit to the setting information based on the structure information of the vehicle type, and transmitted to the setting change unit. Thereby, the setting information of the device that is set based on the physical characteristics of the user set by the user from any vehicle type is converted into position information based on a predetermined coordinate axis and stored. Even when the user uses another vehicle type, based on the structure information of the vehicle type, the stored position information can be converted into setting information for the vehicle type, and the setting can be changed. Therefore, even when the vehicle type is different, it is possible to reliably set the device that is set based on the physical characteristics of the user to the setting intended by the user.

  Preferably, the predetermined coordinate axis is a three-dimensional orthogonal coordinate axis, and the reference point is preferably the position of the accelerator pedal in each vehicle type. Normally, the position of the accelerator pedal cannot be changed by the user. Therefore, by setting the three-dimensional orthogonal coordinate axis based on the position of the accelerator pedal as a coordinate axis for conversion from the setting information to the position information, the setting information of the device that is set based on the physical characteristics of the user Can be easily and reliably converted into position information.

  As described in claim 3, the device that is set based on the physical characteristics of the user takes a stepwise setting form, and the structure information of each vehicle type stored in the database means is: Including the position information of the device when the device is set in each setting stage, and the setting information transmitting means converts the position information of the device stored in the storage means into the setting information Compare the position information of the device included in the vehicle structure information corresponding to the vehicle type information when the device is set at each setting stage, and convert it to the setting stage corresponding to the position information with the highest degree of coincidence. Is desirable. Compares the position information of the device that is set based on the physical characteristics of the user stored in the storage means and the position information of each setting stage of the device in other vehicle models, and the degree of matching is the highest By converting to the setting stage corresponding to the position information, it is possible to easily convert the position information to the setting information.

  According to a fourth aspect of the present invention, it is desirable that the device setting information that is set based on the physical characteristics of the user is setting information related to the steering position of the vehicle. This is because the position of the steering is related to the steering performance of the vehicle, and it is important to set it to the setting intended by the user.

  As described in claim 5, it is desirable that the setting information of the device to be set based on the physical characteristics of the user is setting information regarding the position of the vehicle seat. This is because the position of the seat is related to the operability of the accelerator pedal and the brake pedal, and it is important to set the seat to a setting intended by the user.

  As described in claim 6, it is desirable that the setting information of the device to be set based on the physical characteristics of the user is setting information related to the angle of the vehicle door mirror, fender mirror, or room mirror. This is because the angle of each mirror is related to the field of view displayed on the mirror, and it is important to set the mirror to a setting intended by the user.

  FIG. 1 is a block diagram showing the overall configuration of an in-vehicle device adjustment system according to an embodiment of the present invention. The in-vehicle device adjustment system according to this embodiment includes a vehicle 1 and a data center 9.

  The vehicle 1 includes various sensors, various control devices, a remote controller 5, an ECU 6, a communication device 7, and a display 8.

  The steering position sensor 21 is a sensor that detects a setting stage that indicates a deviation in the front-rear direction of the steering 22 and a setting stage that indicates a deviation in the vertical direction with respect to the initial setting position of the steering 22. The steering position control device 23 is constituted by a control motor, and changes the position of the steering wheel 22 stepwise in the front-rear direction and the up-down direction in accordance with a control signal output from the ECU 6.

  The seat position sensor 31 is a sensor that detects a setting stage indicating deviations in the front-rear direction and the height direction of the seat 32 and a setting stage indicating deviations in the seat inclination angle with respect to the initial setting position of the seat 32. . The seat position control device 33 is constituted by a control motor, and changes the position of the seat 32 in the front-rear direction and the height direction stepwise according to the control signal output from the ECU 6, and changes the seat inclination angle stepwise. .

  The mirror angle sensor 41 is a sensor that detects a setting stage indicating a deviation of the mirror angle with reference to the initial setting positions of the door mirror 42, the room mirror 43, and the fender mirror 44. The mirror angle control device 45 is composed of a control motor, and changes each mirror angle of the door mirror 42, the room mirror 43, and the fender mirror 44 stepwise in accordance with a control signal output from the ECU 6.

The remote controller 5 is a multi-function remote controller having various function keys including at least a setting registration key and a setting reading key. The setting registration key is a key for instructing the data center 9 to register the position and angle of each device at the time when the key is pressed. The setting read key is a key for instructing to change the position and angle of each device based on the contents previously registered in the data center 9. The remote controller 5 also inputs a user ID and a password required for user authentication. The remote controller 5 may be realized by a touch panel of the display 8 or the like.
In addition, when the user is specified, the user ID and password may be replaced by an IC card such as an ETC card or an electronic key, or user authentication may be performed by biometric authentication such as a fingerprint or an iris.

  The ECU 6 is composed of a known computer, and performs user authentication from the user ID and password transmitted from the remote controller 5. Specifically, the user ID is converted based on a hash function such as SHA1 or MD5, and user authentication is performed based on whether or not this matches the password. Further, the ECU 6 stores the vehicle type code (vehicle type information) of the vehicle 1 inside, and together with the setting registration signal, the user ID, the vehicle type code of the vehicle 1, the steering position sensor 21, the seat position sensor 31, and the mirror angle sensor 41. The setting stage (setting information) of the detected steering wheel 22, seat position 32, and angles of the mirrors 42 to 44 is output to the communication device 7. In addition to the setting request signal, the user ID and the vehicle type code of the vehicle 1 are output to the communication device 7. Further, the steering 22, the seat 32, and the mirrors 42 to 44 acquired from the communication device 7 are controlled to change the position and angle of each device described above based on the setting stage indicating the deviation with reference to the initial setting position. Control signals are output to the position control device 23, the sheet position control device 33, and the mirror angle control device 45.

  The communication device 7 is an in-vehicle wireless device, for example, and transmits various signals and various data output from the ECU 6 to the data center 9. Further, various data transmitted from the data center 9 are output to the ECU 6. For communication between the vehicle 1 and the data center 9, for example, a communication function such as a navigation device may be used, or a communication function of a mobile phone may be used.

  The display 8 is a small liquid crystal display, for example, and displays a display screen for requesting input of a user ID and a password and a display screen indicating that the setting change of each device is completed, and notifies the user. The user ID and password input request and the notification of completion of the setting change of each device may be performed by voice from a speaker or the like.

  The data center 9 includes a communication device 91, a storage device 92, and a CPU 93.

  The communication device 91 is a radio base station, for example, and receives various signals and various data transmitted from the vehicle 1 and outputs them to the CPU 93. In addition, various data output from the CPU 93 is transmitted to the vehicle 1.

  The storage device 92 is composed of, for example, RAID, and stores the structure information of each of a plurality of vehicle types as the database 94. The structure information of each vehicle type includes information on the physical structure such as the vehicle width and height of each vehicle type, the installation location of each device, and the deviation from the initial setting position in the steering position, seat position, and angle of each mirror. All the setting stages shown, and coordinate data (position information) indicating the position coordinates on the three-dimensional coordinate axis based on the position of the accelerator pedal of the vehicle type when the device is set in each setting stage are included. Further, the storage device 92 stores the user ID and the device coordinate data in a linked manner. These data may be stored in a DVD-RAM or the like.

  The CPU 93 is, for example, a supercomputer, reads vehicle type structure information corresponding to the vehicle type code acquired from the communication device 91 from the database 94, and sets the steering wheel 22, the seat 32, and the mirrors 42 to 44 that are also acquired from the communication device 91 The stage is converted into coordinate data based on a three-dimensional coordinate axis based on the position of the accelerator pedal of the vehicle type.

  Further, the CPU 93 reads the vehicle type structure information corresponding to the vehicle type code acquired from the communication device 91 from the database 94, and links the coordinate data when each device is set in each setting stage with the user ID to the storage device 92. And the coordinate data having the highest degree of coincidence is retrieved. Then, a setting stage corresponding to this is output to the communication device 91. These processes may be performed, for example, by connecting a plurality of workstations via a network and performing parallel distributed processing.

  FIG. 2 is a flowchart regarding processing for registering the setting of the position and angle of the steering wheel 22, the seat 32, and each of the mirrors 42 to 44 in the data center 9 in the in-vehicle device adjustment system of the present embodiment. The process of this flowchart is executed every time a setting registration key (not shown) of the remote controller 5 is pressed.

  In step 201, the ECU 6 displays a display screen for requesting input of a user ID and password on the display 8, and waits until the user ID and password are input from the remote controller 5.

  In step 202, user authentication is performed from the user ID and password input from the remote controller 5. If the user authentication is successful, the process proceeds to step 203. If user authentication fails, the process ends.

  In step 203, the setting stage in the position and angle of the steering wheel 22, the seat 32, and each of the mirrors 42 to 44 is detected from the steering position sensor 21, the seat position sensor 31, and the mirror angle sensor 41.

  In step 204, the user ID input from the remote controller 5, the vehicle type code of the vehicle 1, and the setting stage of each device detected in step 203 are transmitted to the data center 9 together with the setting registration signal. In step 205, the data center 9 receives the setting registration signal transmitted from the vehicle 1, the user ID, the vehicle type code of the vehicle 1, and the setting stage of each device.

  In step 206, the CPU 93 determines that the setting of each device is registered from the setting registration signal received in step 205. Similarly, in step 205, based on the structure information of the vehicle type corresponding to the vehicle type code received in step 205. The received setting stage of each device is converted into coordinate data based on a three-dimensional coordinate axis based on the position of an accelerator pedal (not shown) of the vehicle type. Normally, the position of the accelerator pedal cannot be changed by the user. Therefore, by using a three-dimensional orthogonal coordinate axis based on the position of the accelerator pedal, the setting stage of each device can be easily and reliably converted as coordinate data.

  In step 207, the coordinate data converted in step 206 is linked with the user ID received in step 205 and stored in the storage device 92 to complete the registration.

  In this flowchart, the setting stage regarding the position and angle of the steering wheel 22, the seat 32, and each of the mirrors 42 to 44 is registered in the data center 9. The position of the seat 32 is related to the operability of an accelerator pedal and a brake pedal (not shown) of the vehicle 1, and the angles of the mirrors 42 to 44 are related to the field of view displayed on the mirror, and are surely set to the setting intended by the user. This is because it becomes important. Of course, the present invention is not limited to these, and any device can be used as long as it is set based on the physical characteristics of the user.

  FIG. 3 is a flowchart regarding processing for changing the position and angle of the steering wheel 22, the seat 32, and each of the mirrors 42 to 44 based on the contents registered in the data center 9 in the in-vehicle device adjustment system of the present embodiment. The process of this flowchart is executed each time a setting read key (not shown) of the remote controller 5 is pressed.

  In step 301, the ECU 6 displays a display screen for requesting input of a user ID and password on the display 8, and waits until the user ID and password are input from the remote controller 5.

  In step 302, user authentication is performed from the user ID and password input from the remote controller 5. If the user authentication is successful, the process proceeds to step 303. If not, the process ends.

  In step 303, the user ID input from the remote controller 5 and the vehicle type code of the vehicle 1 are transmitted to the data center 9 together with the setting request signal.

  In step 304, the data center 9 receives the setting request signal, the user ID, and the vehicle type code of the vehicle 1 transmitted from the vehicle 1.

  In step 305, the CPU 93 determines from the setting request signal received in step 304 that the setting stage of each registered device is requested to be transmitted to the vehicle 1, and links with the user ID received in step 304. The stored coordinate data of each device is read from the storage device 92, and compared with the coordinate data at each setting stage of each device, which is stored in the structure information of the vehicle type corresponding to the vehicle type code received in step 304. The coordinate data having the highest degree of coincidence with this is searched. As a result, the coordinate data of each device can be easily converted to the setting stage.

  In step 306, the setting stage of each device searched in step 305 is transmitted to the vehicle 1. In step 307, the ECU 6 outputs a control signal to the steering position control device 23, the seat position control device 33, and the mirror angle control device 45 so as to change the setting stage of each device to the setting stage transmitted from the data center 9.

  For the part written as “wait” in the above process, a timeout may be provided as an error process to terminate the process.

  As described above, in the in-vehicle device adjustment system according to the present embodiment, the data center 9 sets the steering 22, the seat 32, and the mirror angles 42 to 44 transmitted from the vehicle 1 based on the position of the accelerator pedal of the vehicle type. And converted into coordinate data on the three-dimensional coordinate axes. When the setting request signal is transmitted, the stored coordinate data of each device is converted into the setting stage based on the structure information of the vehicle 1 and transmitted to the vehicle 1. Thereby, even when the user uses another vehicle type, the stored coordinate data is converted into the setting stage in the vehicle type based on the structure information of the vehicle type, and the setting stage can be changed based on this. it can. Therefore, even when the vehicle type is different, it is possible to reliably set the device that is set based on the physical characteristics of the user to the setting intended by the user.

  Next, in the in-vehicle device adjustment system according to the present embodiment, a specific example in which the data center 9 converts the device setting stage, which is set based on the physical characteristics of the user, into coordinate data will be shown. Here, an example is shown in which a steering tilt position setting stage, a seat position (front-rear direction) setting stage, a seat back angle setting stage, and a door mirror angle (vertical direction) setting stage are converted into coordinate data.

  When the data center 9 acquires the vehicle type information and the setting stage of each device from the vehicle 1, the data center 9 refers to the conversion table of the vehicle type stored in the database 94. As shown in FIG. 4, the conversion table stores the reference coordinates of each device, the setting stage of each device, and the deviation from the reference coordinates at each setting stage. As for the reference coordinates of each device, regarding the tilt position, seat position, and door mirror angle, the coordinates of the device are based on the position of the accelerator pedal 51 when each device is set at a specific setting stage (50 in this example). It is. The seat back angle is the coordinates of the device relative to the position of the base 52 of the seat back (see FIG. 5).

  Specifically, the reference coordinates relating to the tilt position are the coordinates of the steering central portion 53 based on the position of the accelerator pedal 51 when the tilt position setting stage is set to 50. The reference coordinates relating to the seat position are the coordinates of the base 52 of the seat back with respect to the position of the accelerator pedal 51 when the seat position setting stage is set to 50. Further, the reference coordinates relating to the door mirror angle are the coordinates of the door mirror upper end portion 54 based on the position of the accelerator pedal 51 when the door mirror angle setting stage is set to 50. The reference coordinates in the seat back angle are the coordinates of the central portion 55 of the seat back based on the coordinates of the base 52 of the seat back calculated in accordance with the setting stage of the seat position.

  Next, the data center 9 reads the coordinate deviation corresponding to the setting stage of each device acquired from the vehicle 1 from the conversion table of FIG. Coordinate data at the setting stage is calculated. Specifically, in the case of the tilt position, for example, if the setting stage transmitted from the vehicle 1 is 1, the coordinate deviation is (0, −10, −20) from the conversion table of FIG. The coordinates (30, 40, 80) obtained by adding the reference coordinates (30, 50, 100) to the coordinate data are used as coordinate data. This coordinate data coincides with the coordinates of the steering central portion 53 based on the position of the accelerator pedal 51 at the setting stage.

  In the case of the seat position, for example, if the setting stage transmitted from the vehicle 1 is 100, the coordinate deviation is (0, 20, 0) from the conversion table of FIG. , 100, 50) is used as coordinate data (30, 120, 50). This coordinate data coincides with the coordinates of the base 52 of the seat back on the basis of the position of the accelerator pedal 51 in the setting stage.

  Further, in the case of the door mirror angle, for example, if the setting stage transmitted from the vehicle 1 is 50, the coordinate deviation is (0, 0, 0) from the conversion table of FIG. , 100) are used as coordinate data as they are. This coordinate data coincides with the coordinates of the door mirror upper end portion 54 based on the position of the accelerator pedal 51 in the setting stage.

  In the case of the seat back angle, since the reference coordinate is the coordinate of the base 52 of the seat back, coordinate data of the seat position calculated in advance is used. For example, if the setting stage transmitted from the vehicle 1 is 1, the coordinate deviation is (0, −25, 25) from the conversion table of FIG. 4, and this is the base back 52 of the seat back that is the reference coordinates. The coordinates are calculated by adding the coordinate data of the sheet position calculated in advance. This coordinate data coincides with the coordinates of the central portion 55 of the seat back on the basis of the position of the accelerator pedal 51 at the setting stage.

  In this example, the door mirror angle is shown only for the setting step in the vertical direction, but the setting step in the horizontal direction can be performed in the same manner from the reference coordinates and the coordinate deviation in each setting step. When the data center 9 calculates the setting stage of each device from the coordinate data, the conversion table of the target vehicle type is read from the database 94 and corresponds to the coordinate data having the highest degree of coincidence with the coordinate data of each device. The setting stage may be the setting stage of the device.

  In the present embodiment, the steering 22, the seat 32, and the mirror angles 42 to 44 are set in a stepwise setting form, but may be set in a continuous setting form. In that case, the setting stage of each device is handled as a setting value.
