    摘要: The present invention relates to a method for operating a high-resolution projection headlight for a motor vehicle. The high-resolution projection headlight has an active LED pixel matrix light source which comprises an LED matrix monolithically integrated into a semiconductor chip with a plurality of light diode-based pixels and a driver circuit for separately controlling each individual pixel within the LED matrix. A current digital image of a sequence of images is continuously rasterized by means of a graphical controller from graphical data with at least one graphical object (50) and is provided for image reproduction with the projection headlight. A value for a thermal loading of the LED pixel matrix light source is continuously determined. During the rasterizing of a current digital image, surface areas (52) of the graphical objects (50) to be projected are at least partially masked with a masking (60, 61) and modulated, provided that the value for thermal loading exceeds a limit value. The invention also relates to a corresponding projection headlight system for a motor vehicle.

    摘要: A method for resolution-optimized control of a motor vehicle light module, wherein the motor vehicle light module is designed to emit segmented light distribution, wherein the motor vehicle light module includes a deflection unit, with which a native resolution of the motor vehicle light module can be visually increased by at least temporary beam deflection by means of the deflection unit, wherein the method includes a) receiving an image signal (S1), wherein the image signal (S1) contains a setpoint image (Ssoll) of light distribution, b) converting the setpoint image (Ssoll) received according to step a) into two lower-resolution images (S_low1, S_low2), and c) controlling the motor vehicle light module, wherein it is controlled in such a way that the two low-resolution images (S_low1, S_low2) of the image pair (S_res) are emitted one after the other by the motor vehicle light module.

    摘要: In one aspect, responsive to determining that an electric vehicle is connected to an external power source, an operator interface of the electric vehicle is enabled to command a headlight of the electric vehicle into an off condition. Responsive to determining that the electric vehicle is disconnected from the external power source and that the electric motor of the electric vehicle is powered, the headlight of the electric vehicle is maintained in an on condition, and the operator interface from commanding the headlight into the off condition is disabled. In another aspect, an electric vehicle headlight may be rendered non-deactivatable when an accelerator of the electric vehicle is enabled, and the headlight may be rendered deactivatable when an accelerator of the electric vehicle is disabled.

    摘要: A vehicle light distribution control apparatus includes a first surrounding environment recognition device configured to recognize a surrounding environment around a vehicle and detect first object information in the recognized surrounding environment, and a second surrounding environment recognition device configured to acquire map information in a predetermined range based on the positional information of the vehicle, and second object information included in the acquired map information, and an illumination device configured to radiate illumination light. An illumination control unit is configured to compare the first object information and the second object information, identify objects that are detected in the second object information and are not detected in the first object information, set the objects as light distribution candidate objects respectively, set light distribution priority levels of the light distribution candidate objects respectively, and perform the light distribution control based on the light distribution priority levels.

    摘要: The present disclosure provides a vehicle light fixture system capable of controlling an optical axis of a vehicle light fixture, without preparing a dedicated light source. A vehicle light fixture system including: circuitry configured to detect a position of a masking target object present in front of a vehicle; set, based on the position of the masking target object, a non-illumination area in which the masking target object is not illuminated; control the vehicle light fixture unit to illuminate an illumination area other than the non-illumination area; store in advance a position of a reference spot pattern that is formed, on a screen disposed ahead of the vehicle, by light emitted from the vehicle light fixture unit installed on the vehicle, in a state in which an optical axis is aligned with a designed optical axis; calculate a misalignment amount; and store the misalignment amount.

    摘要: A method for managing image data in an automotive lighting device includes the steps of providing an image pattern, dividing the image pattern in rows or columns of pixels, and calculating a first gradient value related to the relation between the numeric value of a first pixel and the numeric value of an adjacent pixel. Also included is checking, for each pixel, if the difference between the corresponding gradient value and the first gradient fulfills one of a first or second condition, defining linear segments, compressing the data of the linear segments and sending the compressed data to the light module. The invention also provides an automotive lighting device for performing the steps of such a method.
