  When it is determined in step S11 that the mobile phone with a wireless communication function is not brought into the vehicle, this operation is repeated to stand by. At this time, whether or not the mobile phone with the wireless communication function is brought into the vehicle is determined by the driver with the wireless communication function in the wireless communication unit 8 provided in the navigation device 3 as the in-vehicle information device 1 in FIG. When the mobile phone 41 possessed by the mobile phone 41 is within the communication range of each other and recognizes each other's devices, it is detected that the mobile phone 41 has been brought into the vehicle.

  When it is determined in step S11 that the mobile phone with a wireless communication function has been brought into the vehicle, the wireless communication capable navigation device and the mobile phone are wirelessly connected so that data communication is possible (step S12). Thereafter, the mobile phone number is acquired and stored by the navigation device (step S13). This operation is performed by writing the mobile phone number stored in the mobile phone number storage unit 6 by the mobile phone number input / output unit 7 of FIG.

  Thereafter, it is determined whether or not communication with the emergency call center is carried out by a vehicle-dedicated telephone (step S14). In the communication at this time, the current position data by GPS provided in the vehicle telephone is transmitted to the emergency call center at the start of communication. When it is determined in step S14 that communication with the emergency call center is not performed by the vehicle-dedicated phone, it is determined whether or not the connection between the mobile phone and the navigation device is disconnected in step S19, and it is determined that the connection has not been disconnected yet. When it is done, the process returns to step S14, and the determination as to whether or not communication with the emergency call center is being performed by the vehicle-dedicated phone is repeated. If it is determined in step S19 that the connection between the mobile phone and the navigation device has been disconnected, it is assumed that the driver has gone out of the vehicle, and the process returns to step S11 to determine whether the mobile phone with a wireless communication function has been brought into the vehicle. After the determination, the above operation is repeated.

  On the other hand, when it is determined in step S14 that communication with the emergency call center is being performed using a vehicle-dedicated telephone, it is then determined whether or not communication with the emergency call center has ended (step S15). Here, when it is determined that the communication with the emergency call center has ended, it is determined that various processes after the emergency call have ended and the normal state has been restored, and the process returns to step S11 to repeat the operation.

  When it is determined in step S15 that the communication with the emergency call center has not ended, it is determined whether or not the wireless communication between the mobile phone and the navigation device has been disconnected (step S16). This operation is performed by the driver's vehicle evacuation detection unit 5, and is performed as a function of the wireless communication connection disconnection detection unit 37 in the mobile phone outboard detection unit 36 in the driver's vehicle evacuation detection example 35 in the figure.

  When it is determined in step S16 that the wireless communication between the mobile phone and the navigation device has not been disconnected yet, the process returns to step S15 to determine whether or not the communication with the emergency call center has ended, and thereafter the same operation is performed. repeat. In addition, when it is determined that the wireless communication between the mobile phone and the navigation device is disconnected, operations similar to those in steps S5 and S6 in FIG. 2 are performed. That is, in step S17, the mobile phone number recorded in the navigation device is transmitted to the emergency call center, and in step S8, the guide information is transmitted from the emergency call center to the mobile phone.
