| description | PROBLEM TO BE SOLVED: To provide a key position detection system capable of accurately determining a key position.SOLUTION: An electronic key 2 acquires magnetic flux direction data Da and reception signal intensity data Dc at the time of receiving a radio wave transmitted from a vehicle 1 and key direction information Db as the electronic key 2's direction at the same time. The vehicle 1 acquires communication target direction information Dd as the vehicle 1's direction. A position determination unit 34 determines the electronic key 2's position on the basis of the magnetic flux direction data Da, key direction information Db, reception signal intensity data Dc, and communication target direction information Dd.SELECTED DRAWING: Figure 1
【課題】キー位置を詳細に判定することができるキー位置検出システムを提供する。【解決手段】電子キー２は、車両１から送信された電波を受信したときの磁束方向データＤａ及び受信信号強度データＤｃと、そのときの電子キー２の向きとしてキー向き情報Ｄｂとを取得する。また、車両１は、車両１の向きとして通信対象向き情報Ｄｄを取得する。位置判定部３４は、磁束方向データＤａ、キー向き情報Ｄｂ、受信信号強度データＤｃ及び通信対象向き情報Ｄｄを基に、電子キー２の位置を判定する。【選択図】図１ |
