A device and method for an operator controlled element with haptic feedback dependent on the detection direction are provided. The device includes a base; an actuating part movably supported on the base; an electrical actuator which is attached to the base and acts on the actuating part in order to drive in a moving manner the actuating part in an excitation direction by means of an electrical excitation signal for generating a haptic feedback; a means for detecting an actuation of the actuating part in two detection directions which in each case include a different angular amount with the excitation direction; an evaluation unit, which is configured, if an actuation in one of the two detection directions is detected, to drive the actuator with a specific electrical excitation signal, depending on the result relating to in which of the two detection directions the actuation was carried out.

Operator control element with haptic feedback which is dependent on the detection direction

The invention relates to a display device () in a motor vehicle, consisting of a display (), a transilluminatable screen () disposed behind the display (), a lighting means () and a reflector (), wherein the lighting means () is attached in the display device () between the screen () and the reflector () and the light (L) of the lighting means () can be parallelized and directed towards and through the screen () onto the display () by means of the reflector (), so that symbols that can be changed by means of the screen () can be shown on the display (), and wherein the reflector () is a facetted reflector.

Indicator device in a motor vehicle

The invention relates to a cap () for a display and/or control element. Said cap () comprises a cap member () for covering a light source () and optionally also actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member () in such a way that a symbol represented on or through the luminous area or projection area becomes visible on an operator's side of the display and/or control element by irradiating the symbol by means of a light source (). The luminous area or projection area encompasses a light-permeable metal coating () which is preferably applied using a PVD process. The cap is characterized in that the metal coating () has a three-dimensional contour () for representing the symbol. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.

Display and/or control element in a motor vehicle

An ambient light sensor system is provided for sensing ambient light and light in the area in front of a motor vehicle, wherein the ambient light sensor system includes a light guide element arranged behind a transparent surface of the motor vehicle and at least two sensors arranged on the light guide element.

Device for detecting ambient light and light in the area in front of a motor vehicle

A solar sensor is provided that has microspheres on an interior face of a protective cap or of another radiation-transparent area above a transducer of the sensor. The microspheres scatter the light but at the same time have a much lower damping effect. Preferably, the microspheres are glued to or sealed into the interior face.

Solar sensor having microspheres on the inside face of the protective cap

The invention concerns an operating element, in particular a pushbutton, for a motor vehicle, having at least of a touch-sensitive pushbutton operating on a capacitive basis and a housing, wherein the pushbutton is movably mounted in the housing, wherein a capacitor that forms the capacitance is composed of a metallic area applied to an inner or outer side of a surface facing the user, and the metallic area forms an electrode of the capacitor that is electrically contacted in the housing.

Operating element for a motor vehicle

A control knob for use in a motor vehicle is provided, having a hub for attachment of the control knob to a shaft, a torsion-proof part, a rotatable part, a rotation angle sensor, means for generating rotary haptics, and an electronic system by means of which the components, located in the control knob, can be controlled and the signals of the sensors can be evaluated and via which the control knob can be connected to the on-board electronics of the motor vehicle.
