WIRELESS COMMUNICATION AUTHENTICITY DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To provide a wireless communication authenticity determination system capable of detecting unauthorized communication of a start signal transmitted before a bidirectional communication is established.SOLUTION: A bidirectional communication is established between a vehicle 1 and an electronic key 2 which starts with a start communication transmitted from the vehicle 1 to the electronic key 2. The electronic key 2 calculates a first received signal strength of a radio wave from the vehicle 1 and the vehicle 1 calculates a second received signal strength of a radio wave from the electronic key 2. A verification ECU 4 of the vehicle 1 determines whether the communication between the vehicle 1 and the electronic key 2 which includes the start communication is a normal communication on the basis of the time variation of the first received signal strength and the time variation of the second received signal strength.SELECTED DRAWING: Figure 1
【課題】双方向通信の前に送信される始動信号の不正通信を検出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から電子キー２へと送信される始動通信を契機として、車両１と電子キー２との間の双方向通信が行われる。電子キー２は、車両１からの電波の第１受信信号強度を算出し、車両１は、電子キー２からの電波の第２受信信号強度を算出する。車両１の照合ＥＣＵ４は、第１受信信号強度の時間変化および第２受信信号強度の時間変化に基づいて、始動通信を含む車両１と電子キー２との間の通信が正規通信であるか否かを判定する。【選択図】図１
