  However, in the vehicle sharing system described in Patent Document 1, if a plurality of vehicles are the same vehicle type, the in-vehicle environment set by each user can be applied as it is, but the plurality of vehicles are different vehicle types. In this case, there is a problem that it is difficult to apply the in-vehicle environment set by each user as it is to other vehicles as they are because the presence / absence of the vehicle equipment and the device mounting position are different for each vehicle.

  The present invention has been made to address the above-described problems, and an object of the present invention is to provide an in-vehicle environment information sharing system that allows easy customization of the in-vehicle environment when a single user uses a plurality of vehicles. There is.

Means for Solving the Problems and Effects of the Invention

  In order to achieve the above object, the present invention is an in-vehicle environment information sharing system capable of sharing in-vehicle environment information related to adjustment of vehicle equipment adjusted according to user needs between a plurality of vehicles, An estimation means for estimating in-vehicle environment information desired by the user based on a set value set by the user in one of the vehicles, and in-vehicle environment information estimated by the estimation means in association with the user Storage means for storing, conversion means for reading out in-vehicle environment information stored in the storage means, and converting the read out in-vehicle environment information so as to be compatible with other vehicles of the plurality of vehicles, and for each of the plurality of vehicles In-vehicle environment adjusting means for adjusting the in-vehicle environment based on the in-vehicle environment information after being provided and converted by the converting means. In this case, the in-vehicle environment information desired by the user is, for example, how to see the scenery through the side mirror or the rearview mirror, the margin from the foot to the accelerator pedal or the brake pedal, and the arm when holding the steering wheel. There is a margin.

  In the in-vehicle environment information sharing system of the present invention, the estimating means estimates in-vehicle environment information desired by the user based on a set value in the one vehicle set by the user in one of the plurality of vehicles, and the storing means Stores the in-vehicle environment information in association with the user. Then, the conversion means converts the in-vehicle environment information read from the storage means so as to be compatible with other vehicles among the plurality of vehicles, and the in-vehicle environment adjustment means adjusts the in-vehicle environment based on the in-vehicle environment information. For this reason, even if the vehicle used by the user is composed of different vehicle types, it is possible to adapt the in-vehicle environment for each vehicle based on the in-vehicle environment information stored in the storage means, and the user expects It is possible to automatically realize the in-vehicle environment for each vehicle.

  In this case, the set value is customization information unique to the user in one vehicle, and the estimation means refers to vehicle information including the mounting position of the vehicle equipment in the one vehicle in addition to the customization information. Thus, the vehicle environment information may be estimated. By adding vehicle information including the mounting position of the vehicle equipment in one vehicle to the customization information unique to the user in one vehicle, the customization information unique to the user in one vehicle is customized to the user specific customization information in another vehicle. When converting to, information that becomes the basis of conversion can be easily created.

  In addition, the converting means refers to the in-vehicle environment information stored in the storage means, and refers to the vehicle information including the mounting position of the vehicle equipment in the other vehicle, so that the conversion information is customized to the user-specific customized information in the other vehicle. It is good to be comprised so that it may convert. By adding vehicle information that includes the mounting position of the vehicle equipment in the other vehicle to the in-vehicle environment information (information that is the basis for the above-described conversion) stored in the storage unit, Customized information can be created easily.

  Further, when the in-vehicle environment information is changed by the user in one vehicle of the plurality of vehicles, the estimating means newly estimates the in-vehicle environment information desired by the user based on the changed in-vehicle environment information, and the storage means It is preferable that the in-vehicle environment information stored in is updated to the newly estimated in-vehicle environment information. According to this, the in-vehicle environment information whose setting has been changed in one vehicle can be reflected almost certainly when another vehicle is used.

  Also, an authentication means for authenticating the user when the vehicle is used is provided, and on the condition that the user's acceptance authentication is performed by the authentication means, the in-vehicle environment adjustment means is based on the converted in-vehicle environment information. It may be configured to start adjusting the environment. According to this, by using the user authentication, the conversion of the customization information can be efficiently executed based on the in-vehicle environment information (information as the basis of the conversion described above) stored in the storage unit.

  Further, the authentication unit, the estimation unit, the storage unit, and the conversion unit may be configured as a data center management server capable of exchanging in-vehicle environment information with each vehicle. In this case, in the in-vehicle environment information sharing system, for example, one of a plurality of vehicles is transmitted to the management server by a setting value of the one vehicle set by the user, and the estimation means of the management server is transmitted. The in-vehicle environment information desired by the user is estimated based on the set value, the storage means of the management server stores the estimated in-vehicle environment information in association with the user, and the conversion means of the management server is stored in the storage means. The in-vehicle environment information is read out, and the read out in-vehicle environment information is converted so as to be compatible with other vehicles out of the plurality of vehicles, and then the management server converts the in-vehicle environment information after being converted by the conversion means into the plurality of vehicles. The in-vehicle environment information is transmitted to the other vehicle, and the in-vehicle environment adjusting means of the other vehicle adjusts the in-vehicle environment based on the transmitted in-vehicle environment information, thereby sharing the in-vehicle environment information. According to this, in the system for sharing in-vehicle environment information, the information that each vehicle must hold can be reduced as much as possible, so that the cost on the vehicle side can be reduced. In addition, the system can be easily expanded with respect to existing vehicles.

  The customization information managed by the customization ECU 30A in the customization information storage unit 32 is managed as a setting value unique to the user in each vehicle 3, for example, as shown in FIGS. Specifically, when the user 2 changes the horizontal or vertical angle of the left and right side mirrors 35a and 35b in the vehicle 3 (FIG. 4 illustrates the vehicle a), or changes the horizontal or vertical angle of the room mirror 35c, The mirror ECU 30B7 (see FIG. 2) stores the changed angle (horizontal or vertical angle of each of the mirrors 35a to 35c) and transmits it to the customization ECU 30A. The customization ECU 30A stores the set values of the angles of the mirrors 35a to 35c in the vehicle a in the corresponding storage areas 32a to 32f (see FIG. 4) of the customization information storage unit 32, respectively.

  When the user 2 changes the front / rear position, height position, and angular position of the seat 36, the seat ECU 30B6 (see FIG. 2) stores the changed seat position (front / rear position, height position, angular position). At the same time, the data is transmitted to the customized ECU 30A. The customization ECU 30A stores the seat position setting value, the height setting value of the seat 36, and the angle setting value of the seat 36 in the corresponding storage areas 32g to 32i (see FIG. 4) of the customization information storage unit 32, respectively. .

  Similarly, when the user 2 changes the angular position and weight of the handle 37, the steering ECU 30B5 (see FIG. 2) stores the changed angular position and weight of the handle 37 and transmits it to the customized ECU 30A. The customization ECU 30A stores the angle setting value of the handle 37 and the weight setting value of the handle 37 in the vehicle a in the corresponding storage areas 32m and 32p (see FIG. 4) of the customization information storage unit 32, respectively.

  When the user 2 changes the weight of the accelerator 38a or changes the weight of the brake 38b, the engine ECU 30B2 (see FIG. 2) stores the weight of the accelerator 38a after the change and the brake ECU 30B3 (FIG. 2).

When viewed functionally, including a communication module 41 that exchanges information, the vehicle environment estimation unit 42, a storage unit 43, a customized information conversion unit 44, and a personal authentication unit 45 are configured.

  The personal authentication unit 45 authenticates the personal ID of the user 2 transmitted from the customization ECU 30A. The personal ID of the user 2 is, for example, an ID code of a portable key carried by the user. In addition to or instead of the ID code, authentication information of the user 2 that can identify the user himself / herself (for example, a biometrics such as a fingerprint) Information). Since a plurality of users 2 may use the same vehicle 3, the storage unit 43 stores a personal ID for each user 2. The personal authentication unit 45 functions as an authentication unit of the present invention.

  The in-vehicle environment estimation unit 42 obtains vehicle information specific to the vehicle a based on the customization information set by the user 2 in the vehicle 3, for example, when the customization information is set in the vehicle a. By referencing, in-vehicle environment information desired by the user 2 is estimated.

  Examples of in-vehicle environment information desired by the user 2 include how the scenery is seen through the mirrors 35 a to 35 c and the distance from the accelerator pedal 38 a (brake pedal 38 b) to the back surface of the seat 36. That is, by adding the mounting positions (vehicle information) of the mirrors 35a to 35c to the angles of the mirrors 35a to 35c set by the user 2 (set values in the vehicle a), the background through the mirrors 35a to 35c can be obtained. How it looks to the user 2 can be calculated as an angle value common to each vehicle 3. The in-vehicle environment estimation unit 42 stores the calculated angle values in the corresponding storage areas 43a to 43f (see FIG. 4) of the storage unit 43 as in-vehicle environment information desired by the user 2 regarding the mirrors 35a to 35c.

  Further, the seat pedal set value (set value in the vehicle a) set by the user 2 is added to the accelerator pedal from the tip of the foot by adding the mounting position of the seat 36 and the mounting position (vehicle information) of the accelerator pedal 38a and the like. It is possible to calculate the sheet position taking into consideration the margin desired by the user up to 38a or the like.

  Since the mounting position of the seat 36 and the mounting position of the accelerator pedal 38a and the like are different for each vehicle 3, for example, if the seat position setting value in the vehicle a is applied to the vehicle b as it is, the margin of the toe desired by the user 2 can be obtained. It cannot be reflected. Therefore, the distance from the accelerator pedal 38a etc. to the back of the seat 36 is calculated by adding the seat 36 attachment position and the accelerator pedal 38a attachment position to the seat position setting value (setting value in the vehicle a). It was. The in-vehicle environment estimation unit 42 stores the calculated distance from the accelerator pedal 38a and the like to the back surface of the seat 36 in the corresponding storage area 43g (see FIG. 4) of the storage unit 43. The vehicle interior environment estimation unit 42 functions as the estimation means of the present invention.

  Further, the height of the seat 36, the angle of the seat 36, the angle of the handle 37, the weight of the accelerator 38a, the weight of the brake 38b, the weight of the handle 37, and the volume of the navigation 39 are not particularly required to calculate numerical values. They are stored in the corresponding storage areas 43h, 43i, 43m to 43q (see FIG. 4) of the storage unit 43, respectively.

  Further, the storage unit 43 stores user information such as the sitting height (head position) of the user 2, the height of the shoulder of the user 2, and the distance from the shoulder of the user 2 to the handle 37, respectively. Is stored in ~ 43l. Such information is calculated by calculation based on a set value in the vehicle a, for example (for example, a user's sitting height is calculated from the angles of the mirrors 35a to 35c), set to be input in advance by the user 2, This can be obtained based on image information of the user 2 seated on the seat 36 by a camera (imaging means) installed in the passenger compartment.

  In addition to the in-vehicle environment information stored in the storage areas 43a to 43i and 43m to 43q of the storage unit 43, the above-described user information, for example, the sitting height of the user 2 (the position of the head) is taken into consideration. The accuracy of the angle of 35c can be improved. Further, for example, in addition to the angle of the seat 36 stored in the storage area 43 i, the height of the shoulder of the user 2 and the distance from the shoulder of the user 2 to the handle 37 are taken into consideration, so that the handle desired by the user 2 can be obtained. The angle can be estimated more accurately. The memory | storage part 43 fulfill | performs the function as a memory | storage means of this invention.

  As shown in FIG. 5, the customization information conversion unit 44 reads out the in-vehicle environment information stored in the storage unit 43, and the read out in-vehicle environment information includes, for example, the mounting position of the vehicle equipment 30B in the vehicle b. By referring to the vehicle information, the customized information unique to the user 2 in the vehicle b, that is, the set value in the vehicle b is converted. The customization information conversion unit 44 functions as the conversion means of the present invention.

  Next, the operation of the first embodiment configured as described above will be described. Initially, the case where the user 2 gets in the vehicle b is demonstrated using FIG. In this case, as shown in FIG. 4, the in-vehicle environment information is estimated by the in-vehicle environment estimation unit 42 of the management server 40 based on the set value and the vehicle information in the vehicle a, and the estimated in-vehicle environment information is already stored in the storage unit. If stored in 43, the processes of steps S1 to S7 shown in FIG. 6 are executed in this order.

  Specifically, in the vehicle b, when the customization ECU 30A receives the ID code of the user 2 through a portable key or the like carried by the user 2 (S1), the customized ECU 30A identifies its own vehicle information (specific to the vehicle b). (Including vehicle information) is notified to the management server 40 (S2), and the received ID code of the user 2 is notified (S3).

  After the personal authentication unit 45 authenticates the personal ID of the user 2, the in-vehicle environment estimation unit 42 of the management server 40 is stored (registered) in association with the user 2 from the storage unit 43 based on the ID code of the user 2. In-vehicle environment information (see FIG. 4) is acquired (S4), and is converted into customized information for the vehicle b with reference to the vehicle information of the vehicle b (S5).

  When the management server 40 notifies the customization information for the vehicle b to the customization ECU 30A of the vehicle b (S6), the customization ECU 30A outputs a control signal to each of the ECUs 30B1 to 30B9 corresponding to the notified customization information. Receiving this, each ECU 30B1-30B9 starts customization setting, that is, drives the related actuator (S7).

  Thereby, even if the vehicle 3 used by the user 2 is composed of different vehicle types, it is possible to adapt the in-vehicle environment for each vehicle 3 based on the in-vehicle environment information stored in the storage unit 43 of the management server 40. Thus, the in-vehicle environment expected by the user 2 can be automatically realized for each vehicle 3.

  On the other hand, if the in-vehicle environment information is not yet stored (registered) in the storage unit 43 of the management server 40, the processes of steps S1 to S3, S8, and S9 in FIG. 6 are executed in this order. Specifically, after the processes of steps S1 to S3 are executed, the management server 40 notifies the customized ECU 30A of the vehicle b that the in-vehicle environment information is not stored (registered) (S8). Thereafter, the customized ECU 30A outputs control signals to the corresponding ECUs 30B1 to 30B9 so as to be default setting information (for example, initial state at the time of shipment) (S9).

  Next, a case where the user 2 changes the setting of the customization information in the vehicle a will be described with reference to FIG. Also in this case, as described above, when the customization ECU 30A receives the ID code of the user 2 through a portable key or the like carried by the user 2 (S11), the customized ECU 30A identifies its own vehicle information (specific to the vehicle a). (Including vehicle information) is notified to the management server 40 (S12), and the received ID code of the user 2 is notified (S13).

  After the personal authentication unit 45 authenticates the personal ID of the user 2, the user 2 changes, for example, the position of the seat 36 in the vehicle a (S14), changes the angle of the seat 36 (S15), and further, the side mirror 35a, When the angle 35b is changed (S16), the customization ECU 30A of the vehicle a customizes after the change in steps S14 to S16 when the user 2 gets off (for example, when IG is off and the door is locked). Information is notified to the management server 40 (S17).

  The in-vehicle environment estimation unit 42 of the management server 40 further refers to the vehicle information specific to the vehicle a based on the changed customization information set by the user 2 in the vehicle a, that is, the set value after the change in the vehicle a. Then, the in-vehicle environment information desired by the user 2 is newly estimated (S18). Then, the storage unit 43 updates the registration information, that is, rewrites the previously stored in-vehicle environment information with the newly estimated in-vehicle environment information (S19). After updating the registration information, the management server 40 notifies the customization ECU 30A of the vehicle a that the customization setting can be started based on the newly estimated in-vehicle environment information (S20).

  When a plurality of customization information is changed in this way, for example, by notifying the management server 40 collectively when the user 2 gets off, the setting values related to each other can be taken into consideration at the time of new estimation. As a result, the accuracy of the in-vehicle environment information estimated by the in-vehicle environment estimation unit 42 can be improved.

  In the first embodiment, the in-vehicle environment estimation unit 42, the storage unit 43, and the customization information conversion unit 44 are configured as the management server 40 of the data center 4. Thereby, since the information which each vehicle 3 must hold | maintain can be decreased as much as possible, the cost by the side of the vehicle 3 can be reduced in the vehicle interior information sharing system 1. FIG. In addition, the in-vehicle environment information sharing system 1 can be easily expanded with respect to the existing vehicle 3.

  In this case, the vehicle information stored in the vehicle information storage unit 33 of each vehicle 3 is, for example, only the vehicle type name (vehicle type code), and all vehicle information such as design data indicating physical characteristics of each vehicle 3 is stored in the data center. If the setting is managed by the management server 40 of No. 4, the information that each vehicle 3 must hold can be further reduced, and the cost on the vehicle 3 side can be further reduced.

  Instead of configuring the in-vehicle environment estimation unit 42, the storage unit 43, the customization information conversion unit 44, and the personal authentication unit 45 as the management server 40 of the data center 4, for example, the in-vehicle environment information sharing system 100 in FIG. As shown, each vehicle 130 has an in-vehicle environment estimation unit 131 corresponding to the in-vehicle environment estimation unit 42 of the management server 40 and a customization information conversion unit 132 corresponding to the customization information conversion unit 44 of the management server 40, The management server 141 of the data center 140 may be configured to simply store and hold in-vehicle environment information estimated by each in-vehicle environment estimation unit 131.

  According to this, it is difficult to reduce the cost on the vehicle 3 side, but even if the customization information is frequently changed, the in-vehicle environment information estimation process and the customization information conversion process can be quickly performed. Can do.
