Abstract

The invention relates to a method for deactivating the internal combustion engine (10) of a parallel hybrid drive comprising the internal combustion engine (10), an electric motor (30) and a controllable disconnect clutch (20), which connects the internal combustion engine (10) to the electric motor (30). The method comprises the steps: detection of a decoupling signal; and, when said decoupling signal is detected: changing the speed control by blocking control of the internal combustion engine speed depending on the driver's wishes and bringing the speed of the internal combustion engine (10) to a speed that corresponds to a torque transmission of the internal combustion engine (10) to the clutch (20) of essentially zero. Once control of the internal combustion engine speed depending on the driver's wishes has been blocked, the disconnect clutch (20) is opened. The invention also relates to a corresponding controller.
