Abstract: A sensor system and method for activating the sensor system for transmitting at least one item of first sensor information from a first sensor channel to a first central processing unit and at least one item of second sensor information from a second sensor channel to a second central processing unit. At least one first quality value is determined relating to the functional quality of the first sensor channel at a first control unit on the basis of the first sensor information via the first central processing unit. At least one second quality value is determined relating to the functional quality of the second sensor channel at a second control unit on the basis of the second sensor information via the second central processing unit. A comparison is performed of the first quality value and the second quality value. The sensor system is activated based on the comparison.

Abstract: A pedal sensor is provided with a carrier that can be mounted to a motor vehicle. A housing is formed at the carrier, and a pedal arm is mounted on the carrier so as to be pivotable. A mechanism to transmit movements of the pedal arm relative to the carrier is arranged in the housing, and a sensor for measuring the movements is provided. A damping element is fixed to the carrier in a groove in such a way that any contact between the pedal arm and the carrier is dampened. The damping element is securely held on the carrier. This is achieved by the damping element being secured on both sides against slipping out of the groove.

Abstract: A lighting device for a vehicle, comprising at least one light source, a flat light guide with an input surface and at least one output surface. The light generated by the at least one light source enters the light guide at least partially through the input surface and exits at least partially from the at least one output surface. An LC display which has two opposing, at least partially transparent plates and a liquid crystal layer is arranged between these plates. One of the at least partially transparent plates of the LC display is formed by the flat light guide. The lighting device is configured such that the light emerging from the at least one output surface of the light guide passes at least partially through the liquid crystal layer of the LC display and subsequently through the LC display plate not formed by the light guide.

Abstract: A lighting device for vehicles has a light source and an optical waveguide, which itself includes a first optical waveguide segment with a light entry surface for light from the light source, a second optical waveguide segment with a light emission surface for the light. The emission surface has an optical structure, and a reflection segment between the first and second optical waveguide segments that has a reflective surface that reflects the light entering the optical waveguide toward the second optical waveguide segment. The light emission surface has an edge without an optical structure. The reflection surface has diffusion elements at the edge where part of the light entering the optical waveguide is deflected toward the second optical waveguide segment, and is emitted at the edge of the light emission surface in the second optical waveguide segment.

Abstract: A lighting device for a motor vehicle, in particular a high-definition headlamp, includes an imaging component that has an active surface on which light-emitting diodes or laser diodes are arranged in a matrix to generate pixels in a light distribution in a targeted manner, and a projection lens with which the light emitted from the active surface is projected outward from the motor vehicle when the lighting device is in operation. The lighting device is designed to switch the projection lens from a first setting to a second and from the second setting to the first. The projection lens has a first focal length in the first setting, and a second focal length in the second setting, which is greater than the first focal length.

Abstract: A lighting device for a vehicle contains a light module with at least one light-emitting diode and a light-emitting surface lit by the at least one light-emitting diode, from which light is emitted when the lighting device is in use. The light module has an optical component containing a converter, which is between the at least one light-emitting diode and the light-emitting surface, or forms the light-emitting surface. The lighting device is designed such that the light from the at least one light-emitting diode passes through the optical component and strikes the light-emitting surface. The converter alters the wavelength spectrum of the light passing through the optical component.

Abstract: A method is provided for producing a hologram for a retroreflector. A retroreflector is provided containing numerous facets, each of which reflects light. A photosensitive recording material is applied to the retroreflector. A laser beam is generated, and numerous facets of the retroreflector are successively lit with the laser beam through the recording material, such that the laser beam is reflected by each of the facets and then passes back though the recording material. The laser beam that moves through the recording material toward the facet is a reference beam, and the laser beam reflected back by the facet forms an object beam, such that a segment of the hologram is generated in a part of the photosensitive recording material in front of each of the facets by superimposing the laser beam moving toward the facet with the reflected laser beam.
