Method of detecting the direction of rotation of the secondary side of a starting clutch.

摘要

The method involves detecting the primary (UPrim) and secondary (USek) revolution rates of the primary and secondary sides, operating an actuator (24) in the closing direction if the secondary revolution rate exceeds the primary one, whereby the degree of closure depends on the acceleration of the secondary revolution rate, generating a desired revolution rate, regulating the revolution rate, detecting identical rotation directions of both sides if the primary and secondary rates equalize in a given time and different directions if primary rate falls below the engine idling revolution rate.
