Abstract: A pointer needle for an indication device of a motor vehicle has a transparent optical waveguide that receives light propagating along a direction of propagation at a light-entry side, and emits the light in an emission direction at a light-exit side. The optical waveguide has a scattering side opposite to the light-exit side, the scattering side having steps arranged offset to one another across the propagation direction. When the steps are irradiated by light, the pointer needle provided in the indication device can clearly be perceived in the dark.

Abstract: At least one imaging unit for emitting an image in the form of a beam path and at least one mirror module for deflecting the beam path which is emitted by the imaging unit are included in a head-up display for a motor vehicle. The mirror module includes at least two different mirrors which are movable into the beam path, and a respective curvature of the mirrors is matched to respective vehicle-specific windshield variants. The head-up display may be arranged in the motor vehicle by selecting one of the mirrors whose curvature is matched to the windshield variant, embodied in a vehicle-specific manner, and arranging the selected mirror in a region through which the beam path extends in the case of an activated imaging unit.

Abstract: A determination is made as to whether a driver or a front-seat passenger of the motor vehicle would like to operate a display device. If it is detected that only the driver would like to operate the display device, the display device is put in a first operating mode in which a graphic user interface is displayed exclusively in a driver-side display region of the display device. If it is detected that only the front-seat passenger of the motor vehicle would like to operate the display device, the display device is put in a second operating mode in which the graphic user interface is displayed exclusively in a front-seat-passenger-side display region of the display device.

Abstract: A method for reducing reflection when operating a head-up display of a motor vehicle. The head-up display includes a covering disk element and a dimming element for dimming a deflected light beam of ambient light. A control device determines a light beam path of the deflected light beam, determines a current position and orientation of the dimming element, and determines a region to be kept free of the deflected light beam around the eye point of a user. Based on this, the control device determines whether the deflected light beam passes through the area to be kept free. If so, the control device generates a control signal for adjusting a position of the dimming element to dim the deflected light beam with an adjustment device, and the adjustment device adjusts the position of the dimming element depending on the control signal.

Abstract: A method for operating an air conditioning system of a vehicle includes actuating an operating element of an air vent of the air condition system for a defined first time period, the actuating for the first time period causing activation of a control slider function for adjusting the outflow volume, actuating the operating element for a defined second time period, which is shorter than the first time period, the actuating for the second time period causing a popup menu which optically displays a numerical value of an actual outflow volume of the air vent being displayed on an onboard monitor of the vehicle, and adjusting the outflow volume with a further operating element in the popup menu and simultaneously optically displaying a numerical value of the adjusted outflow volume.

Abstract: The invention relates to a display unit (10) for a vehicle (1), which is designed for representing information and for arrangement in an interior space of the vehicle (1) with respect to a viewing direction (x) of a driver of the vehicle (1), with: a display device (13) which can be connected to a device (30) for operating the display device (13); an OLED display (11) having a three-dimensional geometry for emitting light, wherein the OLED display (11), seen in the viewing direction (x), is arranged so that it overlaps with the display device (13) and, in the overlapping area (11.3), it comprises a passage (11a) through which the display device (13) can be connected to the device (30); a support frame (12) which is designed for the arrangement of the OLED display (11); wherein, in a coupling area, the OLED display (11) is coupled to the support frame (12) and, in a display area, it is geometrically shaped so that it is arranged independently of the support frame (12).
