At this time, if the reply from the mobile phone 2 is not within the predetermined time, the search command is transmitted again.

  When the authentication code from the mobile phone 2 is received, it is compared with a pre-registered authentication code (step S103). As a result of the comparison, if the authentication code from the mobile phone 2 does not match the registration code, an authentication error is output, an error command is transmitted, and this process is terminated (steps S110 and S111).

  On the other hand, if the authentication code from the mobile phone 2 matches the registration code, the wireless connection by Bluetooth is completed and a terminal ID transfer request command is transmitted (steps S104 and S105). Then, when the terminal ID is received from the mobile phone 2, the seat where the mobile phone 2 that transferred the terminal ID is located is determined, and the terminal ID is registered in association with the determined seat (steps S106 to S108).

  When the registration of the terminal ID is completed, the vehicle monitoring device 3 shifts to a standby mode that waits until an interrupt request is received from the mobile phone 2 and ends this process (step S109). This interrupt request is transmitted from the mobile phone 2 based on the terminal operation.

  Steps S201 to S211 in FIG. 7 are flowcharts showing an example of the operation in the standby mode in the vehicle monitoring device 3 in FIG. First, if there is an interrupt request from the mobile phone 2 for which registration of the terminal ID has been completed, the terminal control unit 40 of the vehicle monitoring device 3 locates the mobile phone 2 based on the registration information of the terminal ID. The seat is determined (steps S201 and S202). At this time, if the seat where the mobile phone 2 is located is not a driver's seat, a restriction release command for releasing a restriction mode for restricting terminal operation such as a telephone call is transmitted, and this process ends (step S211).

  On the other hand, if the seat where the mobile phone 2 is located is a driver's seat, the vehicle state is checked (step S203), and if the vehicle is traveling at a speed of 10 km / h or more, terminal operations such as calls are restricted. The restriction command for transmitting is transmitted, and this process is terminated (steps S204 and S205).

  Further, when the vehicle is traveling at a speed of less than 10 km / h, it is checked whether there is any abnormality in the vehicle (steps S204, S206, S207), and if an abnormality is detected, a report for automatically calling the registration destination A command is transmitted and this process is terminated (step S208). If no abnormality is detected, it is determined that there is a traffic jam, a restriction release command is transmitted, and this process is terminated (steps S207, S210, S211).

  If the vehicle is stopped, a restriction release command is immediately transmitted to end this process (steps S204, S206, S209, S211).

  According to the present embodiment, since the terminal ID acquired from the mobile phone 2 is recorded in association with the seat, the mobile phone 2 can be used even when a plurality of mobile phones 2 are brought into the vehicle by the passenger. The seat ID can be determined and the terminal ID can be recorded. Furthermore, since it is determined whether or not the owner of the mobile phone 2 is a vehicle operator based on the acquisition order of the terminal ID, it is determined whether or not the owner of the mobile phone 2 that transferred the terminal ID is a vehicle operator. And the terminal ID can be recorded. Further, since the opening / closing of the door provided at the boarding gate to the driver's seat is detected to determine whether or not the owner of the mobile phone 2 is a vehicle operator, the seat where the mobile phone 2 is located is determined. When it is difficult, it is possible to improve the detection accuracy when determining the seat where the mobile phone 2 is located.

  In the present embodiment, the example in which the vehicle monitoring device 3 acquires and records the terminal ID from the mobile phone 2 has been described, but the present invention is not limited to this.
