PROBLEM TO BE SOLVED: To provide a technique allowing positions of an own vehicle and other vehicles as a counterpart in inter-vehicle communication to be more highly accurately estimated in all vehicles performing inter-vehicle communication.SOLUTION: An own vehicle information management unit and an other vehicle information management unit in an own vehicle estimate vehicle positions by using vehicle information including information on vehicle positions of the own vehicle and another vehicle estimated by an own vehicle information management unit and a different vehicle information management unit in a vehicle having the higher estimation accuracy between vehicle position estimation accuracy of another vehicle determined based on a positional accuracy class of another vehicle received through an inter-vehicle receiver and vehicle position estimation accuracy estimated by the own vehicle information management unit of the own vehicle. Thereby, the positions of the own vehicle and another vehicle as a counterpart in inter-vehicle communication can be more highly accurately estimated in all vehicles performing inter-vehicle communication, and appropriate driving support can be performed using the accurately estimated vehicle position information. |
