ABSTRACT:
A powertrain assembly for an automotive vehicle having an internal combustion engine, transmission, electric induction motor, a clutch for connecting and releasing the engine and transmission, and a controller for controlling the state of engagement and disengagement of the clutch and the torque produced by the motor during the launch. The engine increases torque produced by the induction motor during a vehicle launch condition, permitting the engine to be turned off when the vehicle is at rest. The torque multiplication that would normally be available from a hydrokinetic torque converter is replaced with auxiliary launch torque supplied by the induction motor.
