METHOD FOR AVOIDING SAFETY-CRITICAL ACTIVATION OF A CLUTCH IN A HYBRID MODULE OF A DRIVETRAIN OF A MOTOR VEHICLE

摘要

The present invention relates to a method for preventing the safety threshold activation of a detachable clutch in a hybrid module of a powertrain of a motor vehicle, the hybrid module acting between an internal combustion engine and a transmission and comprising an electric drive, a detachable clutch and a freewheel The detachable clutch is used for starting an internal combustion engine through the transmission of torque supplied from the electric drive unit or power train through a frictionally coupled connection with the electric drive unit or power train, or from the power train for purely electric driving. Used to separate internal combustion engines. In the case of a method for the prevention of safety-critical activation of a detachable clutch in a hybrid module, in which a safety-critical driving situation is reliably prevented, the critical disturbance torque of the detachable clutch is determined for setting a safety interval to be maintained of the open detachable clutch: It is set according to the ambient conditions of the vehicle and/or the vehicle limit conditions.
