PROBLEM TO BE SOLVED: To allow a vehicle to be moved with external force and suppress transmission of extraneous power from a drive source to a drive wheel when a lock state of a power transmission mechanism is manually released, and suppress generation of vehicular vibration or noise due to a sudden start-up of the drive source while the vehicle is moved with the external force.SOLUTION: According to a hybrid controlling-computer 42, a parking lock mechanism 37 includes: a release state determination part 102 for determining whether it is in a release state caused by a manual release mechanism 84; a power transmission cutoff control part 106 for setting a power transmission cutoff state at an automatic speed change part 22 in the case of determining to be the release state; and a drive source activation inhibit part 104 for inhibiting activation of the drive source in the case of determining to be the release state. This makes it possible to cut off the power transmission of a power transmission device 8 at the automatic speed change part 22 and inhibit the activation of the drive source in the case of determining to be the release state, allowing a vehicle to be moved with external force and suppressing transmission of extraneous power from the drive source to the drive wheel.SELECTED DRAWING: Figure 7

    【課題】動力伝達機構のロック状態を手動で解除した際に、車両を外力で移動可能とし、且つ駆動源から駆動輪への不要な動力伝達を抑制するとともに、外力での移動時での駆動源の不意の始動による車両振動や音の発生を抑制する。【解決手段】ハイブリッド制御用コンピュータ42によれば、パーキングロック機構37が、手動解除機構84による解除状態であるかを判定する解除状態判定部102と、解除状態判定時に自動変速部22にて動力伝達遮断状態とする動力伝達遮断制御部106と、解除状態判定時に駆動源の作動を禁止する駆動源作動禁止部104とを含む。このため、解除状態判定時に動力伝達装置8の動力伝達が自動変速部22にて遮断されるとともに駆動源の作動が禁止されることから、車両を外力により移動可能とし、駆動源から駆動輪への不要な駆動力の伝達を抑制できる。【選択図】図7
