To provide a communication device for a vehicle capable of acquiring dynamic information on the other vehicle having the influence on the traveling of the self-vehicle.
This communication device 1 for the vehicle calculates the information on relative position, relative speed and relative moving direction of the self-vehicle and the other vehicle at a point where the traveling of the self-vehicle may be affected by the other vehicle, such as a junction, and searches the other vehicle to be communicated and connected on the basis of a result of calculation. Then the other vehicle to be communicated and connected is determined from the searched other vehicles to perform radio communication. This communication device 1 for the vehicle acquires the information on the other vehicle in time series by radio communication, and represents the information to a driver as needed to allow the driver to recognize the dynamic information of the other vehicle. Whereby the self-vehicle can be smoothly joined, for example, at the junction.
