Title: METHOD FOR REDUCING A ROTATIONAL SPEED OF AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a method for reducing a rotational speed of an internal combustion engine of a hybrid drive comprising the internal combustion engine and an electric motor coupled to the internal combustion engine, comprising detecting (101) an operating state of the hybrid drive, detecting (103) a change in rotational speed of the internal combustion engine, and generating (105) a counteracting torque by way of the electric motor as a function of the detected operating state of the hybrid drive and of the detected change in the rotational speed of the internal combustion engine for reducing the rotational speed of the internal combustion engine.
