PROBLEM TO BE SOLVED: To grasp whether or not a parking mechanism is normal, in advance.SOLUTION: When a shift lever is at a travel position, and a parking mechanism is in a parking lock release state, and when a vehicle is stopped, an engine is operating, a stop request of the engine is not outputted, a brake is an on-state, and an accelerator is an off-state (S100-S140), it is determined that a diagnostic condition is established, a magnetic lock device is turned off (a state that movement of a piston rod is permitted) and working fluid in an oil chamber of a hydraulic actuator is discharged (S150, S160), and it is diagnosed whether or not a parking mechanism 30 is normal, based on whether or not a parking lock state is created (S180-S200). Then after diagnosis, the working fluid is supplied to the oil chamber, the piston rod is moved to a lock release side, and the parking lock state is created (S220).

    【課題】パーキング機構が正常か否かを事前に把握可能とする。【解決手段】シフトレバーが走行用ポジションでパーキング機構がパーキングロック解除状態のときにおいて、車両が停車中で且つエンジンが動作中であり且つエンジンの停止要求がなされておらず且つブレーキオンで且つアクセルオフのときには(S100〜S140)、診断条件が成立していると判断し、磁気ロック装置をオフ(ピストンロッドの移動を許容する状態)とすると共に油圧アクチュエータの油室の作動油を排出させて(S150,S160)、パーキングロック状態が形成されるか否かによってパーキング機構30が正常か否かを診断する(S180〜S200)。そして、診断後には、油室に作動油を供給してピストンロッドをロック解除側に移動させてパーキングロック状態を形成させる(S220)。【選択図】図6
