KEYLESS ENTRY SYSTEM FOR VEHICLE
PROBLEM TO BE SOLVED: To provide a keyless entry system for vehicle which prevents illegal unlocking of a vehicle door and which improves security.SOLUTION: A keyless system K includes a portable machine 10 and an on-vehicle machine 20. The portable machine 10 includes: an RF transmission part for transmitting an operation signal to the on-vehicle machine 20 in one of a plurality of transmission methods; and a control part for determining the transmission method used for transmission of the signal to the on-vehicle machine 20 from among a plurality of transmission methods. The on-vehicle machine 20 includes: a control part for determining a transmission method used for receiving the signal from the portable machine 10 from among the plurality of transmission methods; and an RF reception part for receiving the operation signal transmitted by the portable machine 10 in the transmission method determined by the on-vehicle machine transmission method. In passive transmission between the portable machine 10 and the on-vehicle machine 20 started by the transmission of a response request signal, the control part of the portable machine 10 and the control part of the on-vehicle machine 20 change the transmission method respectively.SELECTED DRAWING: Figure 1
【課題】車両のドアの不正解錠を防止し、セキュリティを向上させる車両用キーレスエントリーシステムを提供する。【解決手段】キーレスシステムＫは、携帯機１０と車載機２０とを有する。携帯機１０は、操作信号を複数の伝送方式のいずれか一つで車載機２０に送信するＲＦ送信部と、車載機２０への信号の送信に用いる伝送方式を、複数の伝送方式から決定する制御部を備え、車載機２０は、携帯機１０からの信号の受信に用いる伝送方式を、複数の伝送方式から決定する制御部と、車載機伝送方式が決定した伝送方式で携帯機１０が送信した操作信号を受信するＲＦ受信部とを備える。携帯機１０の制御部と車載機２０の制御部は、応答要求信号の送信により開始される携帯機１０と車載機２０間のパッシブ通信において、それぞれ伝送方式を変更する構成とした。【選択図】図１
