Abstract
A method for operating a hybrid drive apparatus for a motor vehicle, having an exhaust-gas-producing internal combustion engine and an electric motor. The internal combustion engine and the electric motor, respectively alone or at least sometimes jointly, provide a drive torque, wherein, when a start threshold value is exceeded by a demand variable. The internal combustion engine is started and the drive torque is at least partially generated by the internal combustion engine, and, when a stop threshold value is not met by the demand variable, the internal combustion engine is stopped and the drive torque is generated solely by means of the electric motor.
