Wheel stopper device

A method for bringing a vehicle closer to a vehicle-external primary charging unit configured to inductively charge the vehicle, where the vehicle includes a secondary charging unit, a camera system and a display device, includes the steps of a) capturing a real-time image of a vehicle environment using the camera system, wherein the primary charging unit is included in the real-time image, b) displaying the real-time image on the display device, and c) inserting at least one guide line into the real-time image. The direction and/or curvature of the guide line coincides with a steering angle lock of the vehicle such that the guide line corresponds to the trajectory of the vehicle in the case of the steering angle lock. The position of the at least one guide line in the real-time image of the vehicle environment is selected such that the guide line indicates a movement curve of the secondary charging unit of the vehicle. The method further includes indicating the movement curve of the secondary charging unit relative to the primary charging unit based on a movement of the vehicle by repeating steps a) to c).

A method establishes a wireless communication connection between a vehicle communication unit of a vehicle and a charging station communication unit of a charging station. The method includes the transmission of a low-frequency signal via a LF transmission unit of the vehicle, wherein the LF request signal displays an identifier relating to the vehicle. The method also includes the receiving of the LF request signal via an LF receiving unit of the charging station. The method further includes the transmission of information relating to the identifier in a broadcast message via the charging station communication unit, as well as the receiving of the broadcast message via the vehicle communication unit. In addition, the method includes the checking of whether the broadcast message comprises the information relating to the identifier, and the establishing of a wireless communication connection between the vehicle communication unit and the charging station communication unit, if the broadcast message comprises the information relating to the identifier.

Vehicle charging arrangement

A process for operating a hybrid vehicle in an internal-combustion-engine-driven mode and/or in an electric-motor-driven mode, wherein, on a route section to be traveled and considered for driving in the electric-motor-driven mode, a change to the electric-motor-driven mode will take place only when a threshold value is exceeded which represents, or correlates with the efficiency advantage achievable on the route section by a change from the internal-combustion-engine-driven mode to the electric-motor-driven mode. Starting from the instantaneous position of the hybrid vehicle, the route is examined in an anticipatory manner with respect to such a route section, wherein the threshold value is adapted when such a route section was recognized and a driving through the route section in the electric driving mode would likely lead to a lowering of the state of charge of an electric energy accumulator into a critical state of charge range.

Process for operating a hybrid vehicle

The invention relates to a method for reducing the energy consumption of a motor vehicle having an internal-combustion engine and having at least one electric onboard power supply to which at least a first electric consuming device is connected. In a first operating condition, the internal-combustion engine is operated with a first injection quantity and a first ignition point. In a second operating condition, the internal-combustion engine is operated with a second injection quantity higher than the first injection quantity and a second ignition point. The second ignition point in time is less favorable than the first ignition point in the case of the second injection quantity with respect to the capacity of the internal-combustion engine. Upon detecting a substantially imminent special driving situation, a driving situation detection device causes the internal-combustion engine to change from the first operating condition into the second operating condition.
