Abstract
A hybrid drive apparatus for a vehicle which is capable of improving the response in restarting an engine during the running of a vehicle. As a result, a shock due to deceleration can be reduced. The hybrid drive apparatus for a vehicle incorporates an engine, a motor generator, a clutch, a transmission unit and a control unit for controlling the other elements. The control unit incorporates a standby control device for realizing a constant cranking characteristic to improve the starting response at the start of the engine by transmitting the power of the motor generator to the engine and controlling the engagement pressure of the clutch, thus revolving the engine to a cranking start position.
