To provide a control device for parking lock that can secure functional safety against abnormality occurring to the packing lock utilizing electronic electric communication.SOLUTION: A control device for parking lock comprises: a motor-driven actuator 33 which operates a parking lock 30; an operational position detection part 37 which detects an operational position of the actuator 33; a relay 25 which opens and closes an electricity feed path to the actuator 33; and a control part 40 which controls the opening and closing of the relay 25 and the operation of the actuator 33 and can acquire the operational position. At a request to engage or disengage the parking lock 30, the control part 40 commands the actuator 33 to operate without performing control for closing the relay 25. When operational position information on the actuator 33 acquired from the operational position detection part 37 has changed, the control part determines that the relay 25 is abnormal and stops commanding the actuator to operate. When there is no change, the actuator 33 is caused to operate after closing the relay 25.SELECTED DRAWING: Figure 4

    【課題】電子電気通信を利用したパーキングロックに異常が生じた場合、その異常に対する機能安全を確保できるパーキングロックの制御装置を提供する。【解決手段】パーキングロック30を作動する電動のアクチュエータ33と、アクチュエータ33の作動位置を検出する作動位置検出部37と、アクチュエータ33への給電路を開閉するリレー25と、リレー25の開閉及びアクチュエータ33の作動を制御し、作動位置を取得可能な制御部40と、を備え、制御部40は、パーキングロック30の係合要求又は解除要求が発生した時に、リレー25を閉じる制御を行わずにアクチュエータ33に作動指示を行い、作動位置検出部37から取得したアクチュエータ33の作動位置情報に変動がある場合にはリレー25に異常があると判定して作動指示を停止し、変動がない場合にはリレー25を閉じた後にアクチュエータ33を作動する。【選択図】図4
