PROBLEM TO BE SOLVED: To enable first and second vehicle-mounted communication devices to appropriately perform intervehicle communication without colliding with and interfering with other inter-vehicle communication and communication between a road and a vehicle without requiring complex control.;SOLUTION: A communication state display 51 mounted in a preceding vehicle 5 displays the communication state of the vehicle-mounted communication device 52. A vehicle-mounted communication system 21 mounted in a succeeding vehicle 2 photographs the communication state display 52, analyzes a photograph image, and identifies the communication state of the vehicle-mounted communication device 51. And the vehicle-mounted communication system 21 identifies the position relationship between the succeeding vehicle 2 and a preceding vehicle 5; and specifies the communication method of the intervehicle communication that does not affect the other inter-vehicle communication and communication between the road and the vehicle, and can be made by the communication device 22 for the preceding and succeeding vehicles and the vehicle-mounted communication device 52.;COPYRIGHT: (C)2006,JPO&NCIPI
