ONBOARD APPARATUS, PROGRAM, AND KEYLESS ENTRY SYSTEM
To provide an onboard apparatus, a program, and a keyless entry system with which it is possible to specify the position of a portable apparatus with good accuracy on the basis of the received signal strength of a signal to be measured, irrespective of the type of the portable apparatus.SOLUTION: An onboard apparatus pertaining to one embodiment comprises: a plurality of transmit antennas; an onboard apparatus transmit unit for transmitting a signal to be measured from each of the plurality of transmit antennas; an onboard apparatus receive unit for receiving, from a portable apparatus, a measurement result signal that includes the measurement data of received signal strength of the signal to be measured having been transmitted from each of the plurality of transmit antennas; and an onboard apparatus control unit for calculating a first distance to a plurality of preset areas from the portable apparatus on the basis of a difference between the received signal strengths of the respective signals to be measured that are included in the measurement result signal, and specifying an area from among the plurality of areas to which the portable apparatus belongs on the basis of the first distance.SELECTED DRAWING: Figure 1
【課題】携帯機の種類によらず、被測定信号の受信信号強度に基づいて、携帯機の位置を精度よく特定できる車載機、プログラム、及びキーレスエントリシステムを提供する。【解決手段】一実施形態に係る車載器は、複数の送信アンテナと、前記複数の送信アンテナからそれぞれ被測定信号を送信する車載器送信部と、前記複数の送信アンテナからそれぞれ送信された前記被測定信号の受信信号強度の測定データを含む測定結果信号を携帯機から受信する車載器受信部と、前記測定結果信号に含まれるそれぞれの前記被測定信号の前記受信信号強度間の差に基づいて、前記携帯機から予め設定された複数の領域までの第１距離をそれぞれ算出し、当該第１距離に基づいて、前記複数の領域の中から前記携帯機が属する前記領域を特定する車載器制御部と、を備える。【選択図】図１
