METHOD FOR THE OPERATION OF A DRIVE TRAIN

摘要

The method involves starting an internal combustion engine (2) such that a clutch (4) is closed when an electric motor (3) is driven. The clutch is closed and opened in a controlled manner for starting the engine such that the clutch is brought to a slip by partial closing of the clutch for starting the engine, when the motor is coupled at an output in a torque-proof manner and/or without traction power interruption. The clutch is completely closed before reaching a synchronous speed between the engine and motor, where speed of the motor is larger than starting speed of the engine.
