摘要

PROBLEM TO BE SOLVED: To accurately judge the mode of approach of a moving object.;SOLUTION: When it is judged in a step S104 there is a received radio wave from another vehicle, the arriving azimuth and strength of the radio wave from the other vehicle are judged (step S120). On the basis of the data of the judged arriving azimuth and strength of the radio wave, the change rate in the arriving azimuth of the radio wave and the change rate in the strength of the radio wave are operated (step S122). Then, the possibility of collision is judged while using the operated change rates in the arriving azimuth and the strength (step S124). On the basis of the change rate in the arriving azimuth of the radio wave and the change rate in the strength of the radio wave, the mode of approach can be accurately judged.;COPYRIGHT: (C)2001,JPO
