Abstract
A method for actuating a starting clutch in the power train of a hybrid vehicle, where during a starting phase of the combustion engine by means of an electric machine the starting clutch operating between them is engaged in a first starting phase by means of a pre-control and in a second starting phase depending on the acceleration of the crankshaft of the combustion engine.
Claims9
A method for actuating a starting clutch in a hybrid vehicle having a combustion engine with a crankshaft and an electric machine with a rotor, wherein to start the combustion engine the electric machine is accelerated to a predetermined speed and the starting clutch operating between the electric machine and the combustion engine is engaged depending on a torque to be transmitted through the starting clutch, the method comprising:
- in a first starting phase, setting a pre-control torque of said torque to a predefined value;
- and
- in a second starting phase, regulating a target torque for said torque depending on the acceleration of the crankshaft when a start of the combustion engine is detected;
- wherein a target acceleration used for the regulation is determined depending on a rotational speed difference between the crankshaft and the rotor.
