摘要

Process for controlling a motor vehicle drive branch consisting of an internal combustion engine, an electric machine and a gear mechanism comprises synchronizing the difference in speed at a bridge coupling device using the electric machine by comparing the difference in speed between the electric machine and the engine. An active positive torque in the direction of the crankshaft of the engine is generated by the electric machine in the event of a negative difference in speed. An active negative torque in the opposite direction to the crankshaft of the engine is generated by the electric machine in the event of a positive difference in speed.
