Abstract

A method is for controlling a hybrid drive of a vehicle, which includes at least one internal combustion engine and at least one electric machine, having a first clutch situated between the electric machine and the drive train of the vehicle and a second clutch situated between the electric machine and the internal combustion engine. In the method, a predefinable clutch torque is applied to the second clutch for a start of the internal combustion engine by the operating electric machine, the rotational speed of the internal combustion engine is monitored, and the clutch torque is incremented to a higher value if the rotational speed of the internal combustion engine is less than a predefinable threshold value within a predefinable time interval.
