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. |
