Method for determining plausability of the position of a clutch, method and device for determining the clutch touch point

摘要

The method involves opening an active, old partial transmission assigned clutch and simultaneously closing another partial transmission assigned clutch for converting a channel inserted in old partial transmission to another channel which is inserted in new partial transmission. The difference between the rotational speed of a drive shaft of the double clutch transmission that is rotationally driven by a drive motor and the rotational speed of the inlet shaft of the old partial transmission is detected. Independent claims are also included for the following: (1) a method for determining a point of contact of an actuator operated clutch (2) a device for controlling an actuator for operating a clutch.
