PROBLEM TO BE SOLVED: To provide a keyless entry apparatus capable of accurately operating without being erroneously determined to be an unauthorized relay machine, even when strength of a signal transmitted from a portable machine is weakened by an obstacle.SOLUTION: A keyless entry apparatus performs mutual communication between a vehicle side device and a portable machine. The portable machine includes a portable machine control unit that detects reception intensities of request signals transmitted from a plurality of transmission antennas of the vehicle side device, respectively, and makes a portable machine transmission unit transmit answer signals including first intensity information based on the reception intensity of each of the plurality of transmission antennas. The vehicle side device includes a vehicle side control unit that determines whether or not to perform predetermined control on the basis of information on the position or direction of the portable machine with respect to a vehicle obtained from the first intensity information included in a received answer signal and second intensity information based on the reception intensity of the answer signal at a vehicle side reception unit.SELECTED DRAWING: Figure 1
【課題】障害物によって、携帯機から送信される信号の強度が弱められてしまうような場合があっても、不正な中継機と誤判別されることなく正確に動作することのできるキーレスエントリー装置を提供する。【解決手段】車両側装置と携帯機との間で相互通信を行うキーレスエントリー装置であって、携帯機は、車両側装置の複数の送信アンテナから送信されるリクエスト信号の受信強度をそれぞれ検出し、複数の送信アンテナごとの受信強度に基づく第１の強度情報を含んだアンサー信号を携帯機送信部より送信させる携帯機制御部を有し、車両側装置は、受信したアンサー信号に含まれる第１の強度情報から得られる、車両に対する携帯機の位置または方向についての情報と、アンサー信号の車両側受信部での受信強度に基づく第２の強度情報と、に基づいて所定の制御を行うか否かを判別する車両側制御部を有する。【選択図】図１
