POSITION ESTIMATING DEVICE FOR VEHICLES, POSITION ESTIMATING METHOD FOR VEHICLES, AND POSITION ESTIMATING PROGRAM FOR VEHICLES

摘要

Vehicle-to-vehicle communicating means (101) acquires current position information from peripheral vehicles the current positions of which are identified. The relevant vehicle position correcting means (102) stores the current position information as relevant vehicle position. With this, a position estimating device for vehicles which can identify the relevant vehicle position with a precision less than the maximum reach distance of the vehicle-to-vehicle communication wave even in a situation where conventional relevant vehicle position identifying means does not effectively function can be provided.
