PROBLEM TO BE SOLVED: To provide a hybrid electric vehicle drive unit control unit capable of suppressing the degradation in the durability of the device resulting from the cancellation of a parking lock.SOLUTION: When a shift switching device 58 cancels stopping the rotation of a parking lock gear 82, the stopping of the rotation of the parking lock gear 82 is cancelled in a state in which a clutch CL2 is engaged. Therefore, an impact torque generated due to the cancellation of parking lock is also transmitted to a first planetary gear train 14, an engine 12, a first motor-generator MG1, and the like, thereby making it possible to relax the impact torque transmitted to a second motor-generator MG2. That is, it is possible to provide an electronic control unit 30 of a driving device 10 for suppressing degradation in the durability of the device resulting from the cancellation of the parking lock.

    【課題】パーキングロックの解除に起因する装置の耐久性低下を抑制するハイブリッド車両用駆動装置の制御装置を提供する。【解決手段】シフト切替装置58によるパーキングロックギヤ82の回転の阻止が解除される際、クラッチCL2が係合された状態でパーキングロックギヤ82の回転の阻止を解除するものであることから、パーキングロックの解除に起因して発生する衝撃トルクを第1遊星歯車装置14、エンジン12、及び第1電動機MG1等にも伝達させることで、第2電動機MG2に伝達される衝撃トルクを緩和できる。すなわち、パーキングロックの解除に起因する装置の耐久性低下を抑制する駆動装置10の電子制御装置30を提供することができる。【選択図】図1
