PROBLEM TO BE SOLVED: To provide a communication dishonest establishment prevention system capable of detecting dishonest communication by a method other than a method for detecting presence/absence of vibration by providing a motion sensor on an electronic key.SOLUTION: A communication establishment determination part 25 monitors whether or not ID checking (smart checking) of LF-UHF is established. A vehicle 1 comprises a radar 22, and a distance measurement part 26 senses the surrounding of the vehicle by the radar 22, thereby detecting an object (human body) moving in the vicinity of the vehicle. A communication correctness determination part 27 compares a timing when an electronic key 2 enters a communication area Ea of the ID checking (smart checking) and communication is established, and a timing when it can be determined that, the object enters the communication area Ea based on the radar measurement distance Lx, if they correlate each other, communication of ID checking is determined as right, and if they do not correlate each other, communication is determined as unfair.SELECTED DRAWING: Figure 1

    【課題】電子キーにモーションセンサを設けて振動の有無を検出する以外の方法で、不正通信を検出することができる通信不正成立防止システムを提供する。【解決手段】通信確立判定部25は、LF−UHFのID照合(スマート照合)が確立するか否かを監視する。車両1は、レーダ22を備え、距離測定部26は、レーダ22によって車両周囲をセンシングすることにより、車両付近を動く物体(人体)を検出する。通信正否判定部27は、電子キー2がID照合(スマート照合)の通信エリアEaに入って通信が確立するタイミングと、レーダ測定距離Lxから物体が通信エリアEa内に進入したと判定できたタイミングとを比較し、これらが相関するときには、ID照合の通信を正当と判定し、これらが相関しないときには、通信を不当とする。【選択図】図1
