Abstract

An encounter vehicle determination apparatus: estimates a probability of a host vehicle that enters a host-vehicle intersection on a host vehicle's course on a map; extracts a different-vehicle intersection on a course where a different vehicle matched either to the host-vehicle's course or to a connection road connected with the host-vehicle intersection within a predetermined range, based on vehicle information acquired from the different vehicle via inter-vehicle communications; estimates a probability of the different vehicle entering the extracted different-vehicle intersection; calculates a probability of an encounter between the host vehicle and the different vehicle at the host-vehicle intersection from the estimated probabilities of the host vehicle entering the host-vehicle intersection and the different vehicle entering the different-vehicle intersection; and determines, as the different vehicle that encounters the host vehicle, the different vehicle having the probability of the encounter calculated to be equal to or more than a threshold.
