Progression is measured for torque in an electric motor (EM) and an internal combustion engine (ICE) in a hybrid drive train during a start-up process. An X axis gives the time in seconds. A Y axis gives torque in Newton meters (Nm) in the electric motor and the internal combustion engine. The Y axis also gives the electric motor's speed (n) and that of the internal combustion engine as well as the position of a clutch. Clutch engagement process is started with generating a start signal through a control device. An independent claim is also included for a hybrid drive train with an electric motor, an internal combustion engine linked to the electric motor via a clutch and a unit for controlling the hybrid drive train. Die Erfindung betrifft ein Verfahren zum Starten eines Hybrid-Antriebsstranges, wobei der Hybrid-Antriebsstrang mindestens einen Elektromotor und zumindest einen über einer Kupplung mit dem Elektromotor verbindbaren Verbrennungsmotor aufweist. Ferner betrifft die Erfindung einen Hybrid-Antriebsstrang mit mindestens einem Elektromotor und zumindest einem über eine Kupplung mit dem Elektromotor verbindbaren Verbrennungsmotor und mit einer Steuereinheit zum Steuern des Hybrid-Antriebsstranges.
