Steuerung einer automatischen Kupplung

摘要

The invention relates to the control of an automatic clutch in the drive train of a motor vehicle having a gearbox which can be changed arbitrarily by the driver between drive positions and idle (isolation of gearbox input and gearbox output). During idling, the clutch is essentially kept disengaged in order to reduce noise (gearbox rattling), but is temporarily closed at intervals for very short periods of time, in order to reset a temperature drift of an actuator unit which operates the clutch and which assumes a self-adjusting position when the clutch is engaged. The air conditioning system is switched off temporarily when, during idling, the clutch is engaged temporarily in order to eliminate the risk of rattling noise of the gearbox due to the air conditioning system being on.
