Abstract: The invention relates to a method for controlling a braking system for setting a total braking torque distribution between a first and a second axle of a motor vehicle. The braking system includes a friction braking device and a recuperative braking device. The braking system has a total braking torque composed of a friction braking torque portion and a recuperative braking torque portion. The method include determining, for one axle, a minimal recuperation torque, which is set on that axle, and remains set on that axle for all driving situations as a recuperative braking torque portion.

Abstract: A method for distributing a braking torque requested by a driver over the axles of a motor vehicle. The wheels of the first axle are associated with a first friction brake device and a first electrical machine having a first efficiency and the wheels of the second axle are associated with a second friction brake device and a second electrical machine having a second efficiency, in which, according to the method, the allocation of the requested braking torque over the first and/or second axle and the determination of the components of the recuperation torques to be provided by the first and/or second electrical machine of the requested braking torque is carried out taking into consideration the current driving stability of the motor vehicle.

Abstract: A method for operating a display arrangement of a motor vehicle. A camera continuously captures camera images of a motor vehicle environment and a display device shows the camera images in the form of an alternating image display. An additional, continuously changing image element is shown in or adjacent to the display of alternating images. The image element does not change if a malfunction of the camera and/or the display device and/or another component of the display arrangement results in the display of a still image comprising a single camera image by the display device.

Abstract: A method for operating a motor vehicle. At least one electric engine designed for driving the motor vehicle is used to recuperate electric energy. In this case, a travel of the motor vehicle during a period of time lying ahead is taken into account. During the use of at least one electric engine for recuperating the electric energy, it is taken into account whether during a thermal load of the at least one electric engine in the period lying ahead, a reduction of the power that can be output by at least one electric engine is to be expected. The at least one electric engine then recuperates an amount of electric energy during the deceleration of the motor vehicle which is smaller than the amount of electric energy that can be recuperated during the deceleration by the at least one electric engine. The invention relates in addition also to a motor vehicle.

Abstract: A method for operating an electrically operated or also electrically operable motor vehicle provided with a rechargeable electric energy storage device associated with the drive motor of the motor vehicle. A target charging state is determined for the energy storage device and an operating strategy is determined for a route that is calculated, entered or predicted for the next trip, by which recuperative deceleration is enabled with a specifiable minimum amount for deceleration processes occurring along the route.
