Abstract
A hybrid vehicle includes a combustion engine, an electric motor, and a drive train that is optionally connectible to the electric motor or the combustion engine. An operating mode of the hybrid vehicle is determined automatically as a function of a setpoint torque and an operating state of the hybrid vehicle, the operating mode specifying whether the combustion engine, the electric motor, or the combustion engine and the electric motor is/are used as the drive mechanism of the hybrid vehicle. The operating mode is determined at least such that an efficiency of the drive train including the drive mechanism selected in accordance with the determined operating mode is at a maximum. Depending on the determined operating mode, the combustion engine and/or the electric motor is/are coupled automatically to the drive train for operating the hybrid vehicle.
