Abstract
The invention relates to a method for avoiding safety-critical activation of a clutch in a hybrid module of a drivetrain of a motor vehicle, wherein the hybrid module is effective between the internal combustion engine and the transmission and has an electric drive, the clutch and a freewheel, and the clutch is used to start the internal combustion engine by transmitting a torque, supplied by the electric drive or the drivetrain, by a frictionally locking connection to the electric drive or the drivetrain, or for disconnecting the internal combustion engine from the drivetrain for purely electric driving. In a method for avoiding safety-critical activation of a clutch in a hybrid module in which safety-critical driving situations are reliably prevented, a critical interference torque of the clutch is set as a function of ambient conditions of the motor vehicle and/or peripheral conditions of the vehicle, in order to set a safety distance to be maintained by the open clutch.
