WIRELESS COMMUNICATION CORRECTNESS DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To provide a wireless communication correctness determination system capable of making it difficult to establish fraud using a repeater.SOLUTION: Communication with UHF radio wave of the same frequency is performed between a vehicle 1 and an electronic key 2, the electronic key 2 calculates the reception signal strength of the radio wave from the vehicle 1, and transmits that reception signal strength, as reception signal strength information 30, to the vehicle 1. In the vehicle 1, difference of the notified reception signal strength information 30 and the reception signal strength of radio waves carrying the reception signal strength information 30 is calculated, and communication correctness of smart communication is determined, by confirming whether or not this difference is within a reference range.SELECTED DRAWING: Figure 1
【課題】中継器を使用した無線通信の不正成立を生じ難くすることができる無線通信正否判定システムを提供する。【解決手段】車両１と電子キー２との間を同一周波数のＵＨＦ電波で通信し、電子キー２では車両１からの電波の受信信号強度を算出して、その受信信号強度を受信信号強度情報３０として車両１に送信する。車両１では、通知された受信信号強度情報３０と受信信号強度情報３０が乗った電波の受信信号強度の差分を算出して、この差分が基準範囲にあるか否かを確認することにより、スマート通信の通信正否を判定する。【選択図】図１
