Method for operating drive train of motor vehicle entails determining thermal loading of electric motor which operates clutch and comparing load signal with load limit signal associated with permissible load range of motor

摘要

The method for operating a drive train of a motor vehicle entails determining the thermal loading of the electric motor (14a,14b) which operates the clutch (2a,2b) and generating a load signal which corresponds to the thermal loading. The load signal is compared with a load limit signal which is associated with a permissible load range of the electric motor, and in the event of a deviation of the load signal from the load limit signal the torque of the internal combustion engine is limited. An independent claim is included for a drive train for a motor vehicle which includes a device (15) for determining the thermal loading of the electric motor.
