Drive train operating method for hybrid motor vehicle, involves controlling electric motor of hybrid drive for damping oscillations of drive train such that actual speed of electric motor corresponds reference variable

摘要

The method involves controlling an electric motor (3) of a hybrid drive for damping oscillations of a drive train (1) such that an actual speed of the electric motor corresponds a reference variable dependent on an average wheel velocity or average wheel speed of an inner wheel and an outer wheel of the drive train. The reference variable is dependent on a respective transmission ratio between an output (6) and the electric motor. Oscillations of the drive train are dampened when an internal combustion engine (2) is uncoupled at the output.
