Abstract

A first determination unit provisionally determines collision or non-collision between a vehicle and another vehicle on the basis of positional information of the vehicle and positional information of the other vehicle. A second determination unit changes a determination result to collision when the provisional determination result has been collision N times in succession and when the determination result was previously non-collision, and changes the determination result to non-collision when the provisional determination result has been non-collision M times in succession and when the determination result was previously collision. Here, N is smaller than M. N and M are positive integral numbers.
