ABSTRACT:
A vehicular communications apparatus is configured to calculate information on relative positions, relative velocities, and relative moving directions between own vehicle and other vehicles at a point such as a junction where other vehicles tend to affect running of the own vehicle, and to search for and decide other vehicles which are to be opponents of radio communications, based on a calculated result, and communication opponents are decided from among the searched other vehicles, and radio communications are conducted therewith, and then, the vehicular communications apparatus obtains information on the other vehicles, in a time-sequential manner and by radio communications, and present the information to a driver of the own vehicle from time to time, thereby causing the driver to recognize dynamic information on the other vehicles, enabling the own vehicle to smoothly join a flow of traffic at a junction, for example.
