An agricultural machine includes one or more illuminators to illuminate surroundings of the agricultural machine in a traveling direction thereof, and a controller to control self-driving of the agricultural machine while keeping at least one of the one or more illuminators deactivated at nighttime.

A method is provided for varying an image processing frequency (4, 6) of an HD headlight. The method includes causing the HD headlight to reproduce an output video signal (2) provided by a headlight controller; providing an input video signal (1) to the headlight controller at an input image frequency; using the headlight controller for calculating the output video signal (2) in accordance with at least one image processing function in time within a predefined image processing frequency (4, 6); determining whether the headlight controller is burdened by a computing time expenditure required to perform the at least one image processing function within an available calculation time between two successive output video signals (2) at the predefined image processing frequency (4, 6), and varying the image processing frequency (4, 6) depending on a driving situation. A system also is provided to carry out the method.

A method for operating a headlight system of a motor vehicle, which during operation, illuminates an overall illumination area in the area surrounding the motor vehicle. At least two sensors are provided which detect objects in different associated sensor regions, the sensor regions of the sensors overlapping in an overlap region within the overall illumination area. The data of the sensors are fused to ascertain the existence of an object in the overlap region. Upon confirmation of the existence of the object, a zone in the overall illumination area in which the object is located is selectively excluded from illumination. A motor vehicle having a headlight system operated in this manner is also described.

The present disclosure relates to an illumination system for a motor vehicle for illuminating a carriageway section. The aim is to illuminate the carriageway section in such a way that irritations for other road users are avoided as far as possible. The illumination system includes an information system for providing or detecting a stopping point, an illumination device for projecting a calculated light distribution onto the carriageway section, and a control unit for calculating a light distribution, wherein the calculated light distribution is a one-piece area. The one-piece area begins from a predetermined starting section, which constitutes a proximal lighting section relative to the motor vehicle and does not extend beyond the stopping point. This leads to a shortening of a lane light of the motor vehicle, so that said lane light does not illuminate the lane beyond the stopping point. This is advantageous in particular for crossroads.

Example adaptive vehicle headlights are disclosed. An example system includes a photodetector, an illumination source configured to generate first light during a first operating mode, a spatial light modulator (SLM), and a dichroic filter optically coupled to the illumination source and to the SLM, wherein the dichroic filter is configured to direct the first light to the SLM, and the SLM is configured to direct second light to the dichroic filter during a second operating mode, wherein the dichroic filter is configured to direct the second light having a first color to the photodetector, and direct the first light during the first operating mode.

The invention provides a method for managing image data in an automotive lighting device. This method includes providing a first image pattern, which is sent to a light module, and a second image pattern. A difference pattern is generated by subtracting the second image pattern from the first image pattern and this difference pattern is sent to the light module, so the light module is able to reconstruct the second image pattern from the data of the first image pattern and the difference pattern. The invention also provides an automotive lighting device configured for the method.

A system controls at least one headlight of a motor vehicle provided with at least one light-emitting diode. The system includes at least one camera including a calculator suitable for determining the presence of at least one vehicle to be detected in the area in front of the motor vehicle and suitable for determining the shape of a shadow zone around at least one detected vehicle such that the latter is not blinded by the light emitted by the at least one light-emitting diode of the headlight, a controller for controlling the headlight. The controller is suitable for controlling the state of each light-emitting diode according to the operating state of the headlight and the shape of the shadow zone around the detected vehicle.

A vehicular driver assistance system includes a camera that views through the windshield of the vehicle and a control device having an image processor that processes captured image data. Responsive to processing of captured image data by the image processor, the system adjusts a light beam emitted by a headlamp of the vehicle. The control device, responsive at least in part to image data processing by the image processor, determines when the vehicle is at a construction zone. Responsive to determination that the vehicle is at a construction zone, image processing of image data captured by the camera is adjusted to discriminate construction zone signs from taillights of leading vehicles. Responsive to determination of the vehicle exiting the construction zone, the control device adjusts the light beam emitted by the headlamp of the vehicle responsive to determination of headlamps of approaching vehicles and taillights of leading vehicles.

A motor vehicle having at least one headlight for illuminating the surroundings of the motor vehicle and a control device for controlling the headlight, wherein the headlight comprises a plurality of lighting segments that are arranged in the manner of a matrix and that can be actuated separately by the control device for providing a lighting brightness that can be predefined separately for the individual lighting segments, wherein the control parameter predefining the specific lighting brightness for each of the lighting segments can be calculated by the control device in at least one computing step as a function of input parameters that can be provided by at least one vehicle device, wherein the computing step or at least one of the computing steps may be executed in parallel by the control device for a plurality of the lighting segments.

A vehicle headlight has a segmented light guide device in which segments are selectively controlled to operate in an output state that reduces glare to oncoming vehicle drivers. Vehicle sensors and controller circuitry are used to identify areas of glare removal in the light pattern of the headlight and control the corresponding segments in the light guide device to operate in a selected light output state that reduces glare. The segments can be operated in a focused output state for vehicle driver visibility, or in a scattered output state to reduce glare. The segments can be operated in a clear or transparent output state for vehicle driver visibility, or in a reflected output state to reduce glare. Reflected light can optionally be re-directed. The light guide device can employ bi-stable liquid crystal shuttering or liquid crystal switchable mirror technology.
