ABSTRACT:
Disclosed is a control method and controller for a magnetic powder clutch system including a magnetic powder clutch having an input shaft connected to an engine and an output shaft. In the method, the magnetic powder clutch is energized by an energizing strength which is determined based on a target transmitting torque. The energizing strength is compensated with a predetermined correction factor to realize high accuracy control. Moreover, the correction factor is always updated in response to an error between the target transmitting torque and the detected actual transmitting torque.
