PROBLEM TO BE SOLVED: To improve security performance with respect to relay attack while avoiding communication processing from being complicated.SOLUTION: An on-vehicle control device 10 comprises: an on-vehicle first frequency transmission portion 1 that transmits a response request signal of a first frequency α; an on-vehicle second frequency transmission portion 2a that transmits a response request signal of a second frequency β; an on-vehicle frequency reception portion 2b that receives a response signal of a second frequency β; and an on-vehicle third frequency reception portion 3 that receives a response signal of a third frequency γ. A portable machine 20 comprises: a portable-machine first frequency reception portion 21 that receives the response request signal of the first frequency α; a portable-machine second frequency reception portion 22a that receives the response request signal of the second frequency β; a portable-machine second frequency transmission portion 22b that transmits the response signal of the second frequency β; and a portable-machine third frequency transmission portion 23 that transmits the response signal of the third frequency γ. The on-vehicle control device 10 executes control for a door lock device 6 on the basis of the response signal of the second frequency β and the response signal of the third frequency γ received from the portable machine 20.SELECTED DRAWING: Figure 1

    【課題】通信処理の複雑化を回避しつつ、リレーアタックに対する防犯性を向上させる。【解決手段】車載制御装置10は、第1周波数αの応答要求信号を送信する車載第1周波数送信部1と、第2周波数βの応答要求信号を送信する車載第2周波数送信部2aと、第2周波数βの応答信号を受信する車載第2周波数受信部2bと、第3周波数γの応答信号を受信する車載第3周波数受信部3とを備える。携帯機20は、第1周波数αの応答要求信号を受信する携帯機第1周波数受信部21と、第2周波数βの応答要求信号を受信する携帯機第2周波数受信部22aと、第2周波数βの応答信号を送信する携帯機第2周波数送信部22bと、第3周波数γの応答信号を送信する携帯機第3周波数送信部23とを備える。車載制御装置10は、携帯機20から受信した第2周波数βの応答信号と第3周波数γの応答信号とに基づいて、ドアロック装置6の制御を実行する。【選択図】図1
