Abstract: An LCD display unit for a reflection display system in a motor vehicle includes an LCD pixel matrix for selectively controlling picture elements for presenting a display image on a display area; a backlight arrangement, which is divided into selectively controllable dimming zones in order to illuminate regions containing multiple picture elements with background light; and a control unit, which is configured to control the LCD pixel matrix so that the display image is output, the display image being distorted using a warping function in order to compensate for a distortion of the display image as a result of reflection from a reflection region. The dimming zones have a shape and a size determined by the warping function.

Abstract: A radar-compatible external display device for a vehicle includes a display element for producing a light display external to the vehicle. The display element is disposed in the beam path of a radar system of the vehicle. Each pixel of the display element includes a transparent diffuser assembly and an electrically controllable light source or a deflecting element. Linear dimensions of the display light sources/deflecting elements are several times smaller than a predefined radar wavelength used in the radar system, while distances between adjacent light sources/deflecting elements are greater than said radar wavelength. As a result, radar radiation of the radar system of the vehicle propagates through the display element undisturbed.

The invention also relates to a method for producing such a pair of trousers (H) and to the use of the latter.

Abstract: A system controls a stop function or a door opening function of a vehicle. The system includes an actuating element which is designed to generate an actuation signal depending on an actuation by a vehicle occupant, and a control device which is designed to receive the actuation signal and, in response to receiving the actuation signal and depending on a travel velocity of the vehicle, to trigger either the stop function or the door opening function.

Abstract: 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.

Abstract: An electronic unit in a motor vehicle has a connection for the negative onboard power supply voltage and a connection for the positive onboard power supply voltage, as well as an internal electric supply unit that can be used independently of the polarity of the onboard power supply voltage and independently of the onboard power supply voltage. The unit includes a function block which compares the actual voltage at the connection for the negative onboard power supply voltage with the actual voltage at the connection for the positive onboard power supply voltage. A polarity inversion of the onboard power supply voltage is detected (and a storage of the polarity inversion detection data is caused) if the actual voltage at the connection for the negative onboard power supply voltage is higher than the actual voltage at the connection for the positive power supply voltage, or if the respective actual voltages exceed preset reference values.

Abstract: In an obstacle recognition system in a motor vehicle with an electronic control device and with sensors to detect the distance of an obstacle in a predetermined area, the control device, in a defined partial area of a part, possibly mounted on the vehicle, that could be detected by a sensor as an obstacle, in the event of an actual obstacle being recognized in this partial area, in a first step determines the distance of the obstacle. In a second step, the control device checks to see whether this distance is changing. The alarm that is usually triggered as a function of the distance of the obstacle is suppressed if the distance of the obstacle detected in the defined partial area does not change.
