TORQUE TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To easily reduce pulsation and variation in the torque of an engine.

SOLUTION: At starting the engine 12, the torque pulsation generated in the torque of the engine 12 is obtained from detected signals of a crank angle detection sensor 40 and an engine water-temperature detection sensor 38. A control unit 36 controls an MG 1 by a drive circuit 16MG1 so that damping torque having the same phase as that of the torque pulse is generated, and prevents the torque pulsation of the engine 12 from being transmitted to a ring gear 22 from a planetary carrier 24.
