Abstract:
A control strategy for launching a motor vehicle includes using an electric motor to provide high torque at low speeds during synchronization of launch clutches. An internal combustion engine is started and connected with the electric motor to provide additional torque capacity. Selective engagement and disengagement of an engine disconnect clutch prevents the engine start from interfering with the motor vehicle launch.
