ABSTRACT:
A method for wear-free braking of a vehicle having an electrodynamic drive system including an electric machine and a planetary gearset with a crankshaft of the combustion engine being connected with a first element of the gearset, the electric machine connected to a second element of the gearset and a transmission input shaft connected to a carrier of the gearset. The friction clutch serves as a bridging clutch to detachably connect two elements of the gearset such that when the clutch is engaged, the gearset is locked and the combustion engine operating in thrust mode applies braking torque to the drive train, the clutch is disengaged and a transmission input speed exceeds a predetermined threshold value, the speed of the combustion engine is raised to a maximum speed by appropriate control of the electric machine.
