In FIG. 4, the control unit 40 of the vehicle terminal device 3 constantly monitors the determination output of the travel determination unit 39 that determines the travel of the vehicle based on the signal from the sensor 38 (step S <b> 11). If it is determined that the vehicle is traveling, the process proceeds to step S12, and if not, the process returns to step S11. In step S12, it is determined whether or not the communication I / F unit 35 that performs data communication with the mobile communication terminal device 1 is in use. For example, when the vehicle 2 is traveling while the communication I / F unit 35 receives map information data or the like from the mobile communication terminal device 1, it is determined to be in use. When receiving from the mobile communication terminal device 1 (use state), the process returns to step S11. When not receiving (not use state), the process proceeds to step S13.

  Then, a timer set for a predetermined time is made (step S14), and specific signal information corresponding to the difficulty of driving operation (curve running or straight running, presence / absence of intersection passing, etc.) is extracted (step S15). That is, for example, it is determined that it is difficult to drive the vehicle when driving on a curve or passing through an intersection, and the wireless communication unit 11 is not connected to the mobile communication terminal device 1 as specific signal information registered in advance from the storage unit 37. A command signal for operation (for example, power off) is extracted (step S15), and this command signal is transmitted over a predetermined time set by the timer via the specific signal transmitter 36 (steps S16 to S17). Alternatively, for example, when the vehicle is traveling straight and there is no intersection passing, the ease of driving the vehicle is determined, and as the specific signal information registered in advance from the storage unit 37, for example, the wireless communication unit 11 is turned on with respect to the mobile communication terminal device 1. The permission command signal permitting only the mail reception and the voice output of the mail information is extracted while maintaining the above (step S15), and this permission command signal is transmitted over the predetermined time set by the timer via the specific signal transmission unit 36. (Steps S16 to S17). If the timeout has occurred, the transmission of the specific signal is stopped (step S18), and the process returns to step S11.

In FIG. 5, the control unit 21 of the mobile communication terminal device 1 receives the specific signal 6 from the vehicle terminal device 3 via the specific signal receiving unit 14 (step S21). If the specific signal 6 is received, the type of the specific signal is determined (step S22). For example, the content of the specific signal is an instruction that disables communication with the base station (for example, powering off the wireless communication unit 11), or a permission instruction that permits only mail reception and voice output of the mail information It is determined whether or not. Next, the restriction setting information based on the specific signal 6 stored in advance in the storage unit 20 is read (step S23), and it is determined whether the restriction setting is made (step S24). If the communication restriction is not set, the process ends. If the restriction is set, the communication restriction of the mobile communication terminal device 1 is set according to the type of the specific signal and the restriction setting information (step S25). It is determined whether the specific signal is continuously received (step S26). If the specific signal is continuously received, the process returns to step S25. If the specific signal is not continued, the communication restriction is canceled (step S27). That is, the communication regulation is continued while the specific signal 6 is being received via the specific signal receiving unit 14.

  Note that the base station 4 can be used as an avoidance means when the communication function is not recovered even when the user resumes the communication with the mobile communication terminal device 1 in an emergency or when the user ends the operation of the vehicle due to a device malfunction or the like. The communication of the mobile communication terminal device 1 may be recovered by receiving a predetermined signal from the mobile phone.

  According to the in-vehicle communication system that operates as described above, the mobile communication terminal device receives map information, traffic jam information, store information, sightseeing spot information, etc. from a server device (not shown) via a base station, for example, In the case of transmission to a terminal device (including a navigation device), communication can be maintained and continued regardless of the traveling state of the vehicle, so that convenience for the user is improved. In addition, since the restriction content (communication prohibition, terminal function restriction) can be set according to the road running condition, etc., fine control according to the situation can be made regarding the communication restriction of the mobile communication terminal device.
