VEHICLE COMMUNICATION SYSTEM, PORTABLE DEVICE, AND ON-VEHICLE DEVICE
To provide a vehicle communication system, a portable device, and an on-vehicle device.SOLUTION: An on-vehicle communication system comprises: an on-vehicle device transmitting signals sequentially from a plurality of spaced-apart transmitting antennas mounted on a vehicle; and a portable device having a plurality of receiving antennas and transmitting a response signal according to signals received by the plurality of receiving antennas. The portable device comprises: a measuring unit measuring the signal strength of the received signal for each receiving antenna; and an inhibit unit inhibiting the transmission of the response signal when the signal strength of each of the received antennas measured for each of the plurality of received signals is maximum at a specific one of the plurality of receiving antennas without depending on the plurality of signals.SELECTED DRAWING: Figure 8
【課題】車両用通信システム、携帯機及び車載機の提供。【解決手段】車両に離隔配置された複数の送信アンテナから順次的に信号を送信する車載機と、複数の受信アンテナを備え、複数の受信アンテナにて受信した信号に応じて応答信号を送信する携帯機とを備える車両用通信システムであって、携帯機は、受信した信号の信号強度を受信アンテナ毎に計測する計測部と、受信した複数の信号の夫々について計測した受信アンテナ毎の信号強度が、複数の信号に依らず、複数の受信アンテナのうちの特定の１つで最大となる場合、応答信号の送信を禁止する禁止部とを備える。【選択図】図８
