IN-VEHICLE MACHINE, VEHICLE COMMUNICATION SYSTEM, AND ARRIVAL DIRECTION ESTIMATION METHOD
To provide an in-vehicle machine, a vehicle communication system, and an arrival direction estimation method.SOLUTION: An in-vehicle machine makes a plurality of transmission antennas separately arranged on a vehicle transmit signals, so as to perform processing according to responce signals from a portable unit which has received the signals. The in-vehicle machine includes: a reception part for receiving response signals through each of a plurality of reception antennas separately arranged on the vehicle; and an estimation part for estimating arrival directions of the response signals on the basis of phase difference of the response signals received through the plurality of reception antennas.SELECTED DRAWING: Figure 7
【課題】車載機、車両用通信システム及び到来方向推定方法を提供する。【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信号を送信させ、信号を受信した携帯機からの応答信号に応じて処理を行う車載機であって、車両に離隔配置された複数の受信アンテナの夫々を通じて応答信号を受信する受信部と、複数の受信アンテナの夫々を通じて受信した応答信号の位相差に基づき、応答信号の到来方向を推定する推定部とを備える。【選択図】図７
