A method for operating a hybrid vehicle which comprises at least one internal combustion engine with a fuel tank and a filter, and an additional motor for driving the vehicle. The filter is designed to receive fuel vapors from the fuel tank in a filtering mode and to discharge the fuel vapors to the internal combustion engine in a flushing mode. In the method, a current operating point of the internal combustion engine is detected and the flushing mode of the filter is activated according to the current operating point and an operating time of the vehicle.

Method for operating a hybrid vehicle

In a method and a device for controlling hybrid functions in a motor vehicle, including at least one control unit, hybrid functions of a motor vehicle are controlled by the control unit, the control unit switching off at least one hybrid function above a predetermined battery temperature.

Method and device for controlling hybrid functions in a motor vehicle

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.
