Abstract: When the engine being in an idling operation and it is in a running state (S410, S420), a value 1 is set to a learning-determination flag F1 (step S460) and the learning of the idling control value is performed when the transmission is in the state of Lo gear and it is not immediately after a Hi-Lo shifting has been performed (S430 to S450).

Abstract: In a power output apparatus of the present invention, a control unit sets a WOT (wide open throttle) line L2, where the maximum torque of an engine attains, as a boundary between an over drive area and an under drive area in the case where a rotor shaft of an assist motor is set in a state of over drive linkage. The control unit determines a target working point of an outer rotor shaft of a clutch motor, which functions as a drive shaft, based on an externally required output, and selects the WOT line L2 as a performance line of the engine in the case where the target working point of the outer rotor shaft is present in the under drive area. The control unit then sets a switching instruction flag, in order to change the state of linkage of the rotor shaft of the assist motor from the state of over drive linkage to a state of under drive linkage.

Abstract: A hybrid electric vehicle includes an internal combustion engine, a multi-speed automatic transmission, and an electric machine operable in a motoring mode and a generating mode. A compound planetary gear set operatively couples the engine, transmission and electric machine. The electric machine is operable during periods of vehicle launch to provide a reaction torque for the planetary gearset such that torque is supplied to the input of the transmission and the reaction torque energy is converted to electrical energy for storage in a vehicle battery pack battery. The method employs a combination of open loop torque control and closed loop speed controls responsive to rotational parameters of the vehicle drivetrain including engine speed, electric machine rotor speed and transmission input speed to control the generator torque of the electric machine to thereby produce the reaction torque for accelerating the vehicle and for producing electrical power during the vehicle launch.
