The paper reports upon the invention, development and critical assessment of key subsystems applied to electrically actuated AMTs and DCTs, and describes their simulation, design, rig testing and associated demonstration vehicles. Specially, these devices address the following: direct clutch and gear actuation using a moving magnet linear actuator; devices to reduce the actuation power for sustained control of wet or dry clutches targeting an average actuation energy over the NEDC cycle of < 30W electrical power; thermal management of a dry clutch using a heat transfer device to maintain facing materials below 220°C; requirement for a device to prevent roll-back on an incline and hence avoid significant clutch heating; in combination, increase the life of DCT dry clutch modules to 150,000 miles for small and medium cars.
