In FIG. 2, description of an input path for signals or information indicating the on / off state of the IG switch to the in-vehicle communication device 20 is omitted. The in-vehicle communication device 20 can acquire the on / off state of the IG switch directly from the IG switch or indirectly from the in-vehicle device that performs processing related to the on / off state of the IG switch.

  When the IG switch is off (S1: NO), the processing unit 21 waits until the IG switch is turned on. When the IG switch is turned on (S1: YES), the processing unit 21 transmits the vehicle information stored in the storage unit 22 to the driving information storage device 40 in the outside communication unit 24 (step S2). Then, the transmitted vehicle information is deleted from the storage unit 22 (step S3).

When the IG switch is in the off state (S9: YES), the processing unit 21 ends the vehicle information collection / transmission process.

  The in-vehicle communication device 20 according to the present embodiment acquires and stores the driver's face image captured by the in-vehicle camera 3 and the driver's biometric information detected by the biosensor 5 as driver information. The information is stored in the unit 22 and transmitted to the driving information storage device 40. For example, when the IG switch of the vehicle 1 is in an on state, the in-vehicle communication device 20 periodically acquires the driver information every tens of minutes or every several hours. However, in the case where a fingerprint sensor or the like is provided as an in-vehicle instrument panel or the like as the biometric sensor 5 and it is difficult to obtain biometric information while the vehicle 1 is traveling, information is provided only when the vehicle 1 is not traveling. It is good also as a structure which acquires.

It is determined whether or not the seating state has been changed (step S21).

  When the driver's seat changes to the seated state (S21: YES), the processing unit 21 acquires biometric information by the biometric sensor 5 (step S24). At this time, the processing unit 21 may display a message or the like on, for example, a display device provided in the vehicle, and prompt the driver to acquire biometric information. Further, the processing unit 21 captures an image of the driver with the in-vehicle camera 3 (step S25), and acquires a captured image of the driver's face. Next, the processing unit 21 stores the acquired driver information in the storage unit 22 (step S26), and returns the processing to step S21.

  If the driver's seat has not changed to the seating state, that is, if the seating state or the non-sitting state is maintained (S21: NO), has the processing unit 21 passed a predetermined period since the previous acquisition of the driver information? It is determined whether or not (step S22). When the predetermined period has not elapsed (S22: NO), the processing unit 21 returns the process to step S21 and waits until the driver's seat changes to the seated state or the predetermined period elapses.

  When the predetermined period has elapsed (S22: YES), the processing unit 21 determines whether or not the vehicle 1 is traveling (step S23). The processing unit 21 can determine whether or not the vehicle 1 is traveling, for example, according to the vehicle speed detected by the vehicle speed sensor 10 or the state of the shift lever of the vehicle 1. When the vehicle 1 is not traveling (S23: NO), the processing unit 21 acquires the biometric information by the biosensor 5 (step S24) and the driver's imaging by the in-vehicle camera 3 (step S25). The stored driver information is stored in the storage unit 22 (step S26), and the process returns to step S21. When the vehicle 1 is traveling (S23: YES), the processing unit 21 does not acquire the biometric information by the biometric sensor 5, performs the imaging of the driver by the in-vehicle camera 3 (step S25), and acquires the acquired driving The person information is stored in the storage unit 22 (step S26), and the process returns to step S21.

  Note that the driver information stored in the storage unit 22 is appended with time information at which the driver information is acquired and position information of the vehicle 1 at the time of acquisition. The time information may be obtained based on GPS signals, or may be obtained by a clock function in the vehicle 1 or the like. In the present embodiment, the time information attached to the driver information includes information related to the date. The position information is obtained based on the GPS signal.

  Moreover, although illustration is abbreviate | omitted in the flowchart of FIG. 4, the vehicle-mounted communication apparatus 20 transmits the driver information which it acquired and memorize | stored in the memory | storage part 22 to the driving | operation information storage apparatus 40 at an appropriate timing. In the present embodiment, the in-vehicle communication device 20 transmits the driver information together with the vehicle information to the driving information storage device 40 when transmitting the vehicle information stored in the storage unit 22. That is, in step S2 of the flowchart of FIG. 3, the in-vehicle communication device 20 transmits the vehicle information and driver information stored in the storage unit 22 to the driving information storage device 40, and the vehicle information and driver information already transmitted in step S3.

For example, when the driver is specified by biometric authentication processing based on the biometric information such as the driver's vein or fingerprint acquired by the biometric sensor 5, the driver specifying information 55 is obtained in advance. The pattern image such as veins or fingerprints or information of the pattern can be converted into numerical information.

  When the driver-specific function according to the present embodiment is used, the driver of the vehicle 1 needs to register his / her face image and biological information in the driving information storage device 40 in advance. The driving information storage device 40 stores driver identifying information 55 for one or more drivers for the vehicle ID assigned to the vehicle 1. Based on the driver information received from the in-vehicle communication device 20, the driving information storage device 40 reads the driver identifying information 55 related to the vehicle ID attached to the driver information, and the received driver information is registered. It is determined on the basis of the driver specifying information 55 whether the driver belongs to the driver and, if a plurality of drivers are registered, which driver the driver belongs to.

  Furthermore, in the storage unit 42 of the driving information storage device 40, driver specifying information 55 is stored for a plurality of vehicles, and driver specifying information 55 for a plurality of drivers is stored. For this reason, the driving information storage device 40 can target not only a driver related to the vehicle ID attached to the received driver information but also a driver related to a different vehicle ID. However, in this embodiment, the target of the driver's specific process is one or a plurality of drivers registered for the vehicle ID, and drivers related to other vehicle IDs are not processed. That is, when the driver identification information 55 for the three users A to C is registered in advance for the vehicle ID, the driving information storage device 40 displays the driver information to which the vehicle ID is attached as an in-vehicle communication device. If it is received from 20, it is determined which of the users A to C the driver of the vehicle 1 is. In this case, there are four types of processing results of the driver specifying process: user A, user B, user C, or unknown (unregistered).

  The driver identification information 56 stored in the storage unit 42 is a processing result of the driver identification process described above. The driver information received from the in-vehicle communication device 20 includes a vehicle ID, time information, and position information, and the driving information storage device 40 determines the driver specified in the driver specifying process and the driving used for specifying. The vehicle ID, the time information, and the position information attached to the driver information are associated with each other and stored in the storage unit 42 as the driver specifying information 56. Based on the driver identification information 56 stored in the storage unit 42, it is possible to confirm which driver is driving the vehicle 1 to which the vehicle ID is attached at a certain time and position. .

The driver specifying unit 51 of the processing unit 41 of the driving information storage device 40 determines whether or not the driver information is received from the in-vehicle communication device 20 by the communication unit 43 (step S31). When driver information is not received (S31: NO), driver specific part 51 stands by until driver information is received. When driver information is received (S31: YES), driver specific part 51 acquires vehicle ID attached to received driver information (Step S32).

  Next, the driver specifying unit 51 reads out the driver specifying information 55 corresponding to the acquired vehicle ID from the storage unit 42 (step S33). The driver specifying unit 51 performs face authentication processing, biometric authentication processing, and the like using the received driver information and the driver specifying information 55 read in step S33 (step S34), and adds the received driver information to the received driver information. It is determined whether or not the corresponding driver exists among the drivers whose information is stored as the driver specifying information 55 (step S35). When the corresponding driver exists (S35: YES), the driver specifying unit 51 sets the corresponding driver as the specified result (step S36). When there is no corresponding driver (S35: NO), the driver specifying unit 51 sets the specified result as unknown to the driver (step S37). After identifying the driver in step S36 or S37, the driver identifying unit 51 associates the driver identification result with the vehicle ID, time information, and position information attached to the received driver information. It memorize | stores in the memory | storage part 42 as the specific information 56 (step S38), and complete | finishes a driver specific process.

  The vehicle information 57 stored in the storage unit 42 of the driving information storage device 40 is vehicle information received from the in-vehicle communication device 20.
