摘要

PROBLEM TO BE SOLVED: To provide a distance recognition system for searching a distance to a stop line ahead of a vehicle traveling direction by enhancing precision.;SOLUTION: A prescribed range on a road R is defined as a communication area A, and uplink information transmitted by an in-vehicle unit 1 is received by an optical beacon 2, and prescribed downlink information is repeatedly transmitted to the in-vehicle unit 1. The downlink information includes distance information about a distance L from a communication region A to a front stop line P and transmission lapse information with the transmission of the first transmission of the downlink information after the reception of the uplink information as a reference. The in-vehicle unit 1 receives the downlink information, and corrects the distance information by using the transmission lapse information included in the downlink information, and searches the distance L1 to the stop line P.;COPYRIGHT: (C)2009,JPO&INPIT
