Method for avoiding a safety-critical operation of a separating clutch in a hybrid module of a drive train of a motor vehicle

摘要

The invention relates to a method for preventing safety-critical activation of a clutch in a hybrid module of a motor vehicle power train, the hybrid module being effective between an internal combustion engine and a transmission and comprising an electric drive, a clutch and a freewheel, and the clutch being used to start the internal combustion engine by transmitting torque, which is supplied by the electric drive or the power train, as the clutch frictionally engages with the electric drive or the power train for purely electric driving. In a method in which the error tolerances of the entire system can be taken into consideration, a safety gap of the disconnected clutch that has be be maintained is adjusted in accordance with the ambient conditions around the motor vehicle and/or the boundary conditions of the vehicle.
