A method for controlling a lighting device of a motor vehicle including at least one lighting module having a plurality of light sources, each of the light sources being designed to emit a luminous pixel, and a controller able to selectively control each of the light sources by applying thereto an electrical signal having a parameter of a value determined for the emission of a luminous pixel of given brightness.

The invention consists of vehicle headlight system 1 comprising light sources 5 which shine light outwards from the vehicle and photosensing devices 9 which sense light shining towards the vehicle. The photosensing devices 9 are located adjacent to light sources 5 and a shield reduces detection of light spill. In a high-beam mode, a controller causes the light sources 5 to shine light at a high-beam brightness level. In a low-beam mode, the controller receives signals from the photosensing devices 9, uses the signals to determine a position of an oncoming vehicle and causes light sources 5 shining light to the position to reduce their brightness to a low-beam brightness level or to zero. As the position of the oncoming vehicle changes, the controller continuously receives signals from the photosensing devices 9, uses the signals to determine a new position of the oncoming vehicle and causes light sources 5 shining light to the new position, to reduce their brightness.

A method for correcting a light pattern provided by a first lighting device and a second lighting device. The first lighting device projects a first light pattern and the second lighting device projects a second light pattern. There is an overlapping zone between the first light pattern and the second light pattern. The method includes the steps of, for each lighting device, dividing the light sources in groups, each group being associated to a projection distance, calculating an overlapping region as a function of the projection distance, calculating a number of affected light sources for each group as a function of a representative dimension of the overlapping region and attenuate the intensity of the light emitted by the affected light sources in each group of each lighting device, following a monotonic attenuation pattern from 100% attenuation in the first affected light source to 0% in the last affected light source. The invention also provides an automotive lighting device assembly with control means to perform the steps of this method.

A high-definition vehicular headlamp has a light module configured to produce a matrix of light-emitting points each of which has a coordinate pair. The headlamp generates a light image in front of the vehicle, and the light image is divided into a matrix of pixels that correspond respectively to the light-emitting points of the light module. A specified partial image content is generated in a partial region of the light image. The partial image content acts upon a set of coordinate pairs of light-emitting points, including coordinate pairs having defective light-emitting points that could cause pixel errors. A displacement vector is formed by comparing coordinate pairs of defective light-emitting points with the set of coordinate pairs of the light-emitting points on which the partial image content acts, and the partial image content is reproduced in the partial region of the light image that has been displaced by the displacement vector.

An illumination device having a first and second light module each having a light source and an optical unit for generating a first illumination region and a second illumination region, respectively. A control unit controls the first light module and the second light module, so that a larger number of light pixels are imaged in the first illumination region than in the second illumination region with respect to a surface of equal size, wherein the light pixels of the first light module have a greater illumination intensity than the light pixels of the second light module. The control unit acts upon the light sources of the first light module or the second light module such that the light sources of the first and second light module are each operated with a thermal output within a tolerance band and below a maximum thermal output of the at least one light source.

A system for adaptive lights for use in a vehicle includes a headlight configured to generate light to be at least partially directed away from the vehicle to illuminate a portion of an environment of the vehicle. The system further includes a sensor configured to detect data corresponding to an environmental condition in the environment of the vehicle. The system further includes an electronic control unit (ECU) coupled to the headlight and the sensor and configured to determine the environmental condition based on the detected data and to adjust an intensity and an orientation of the light generated by the headlight based on the environmental condition.

The disclosure provides systems and methods for detecting and responding to a power outage. The methods use sensors of vehicles to detect an indication of a power outage. Once the power outage is validated, the lighting systems of the vehicles are used to illuminate locations so that pedestrians can walk along sidewalks or through parking garages. For example, the vehicles can be arranged to provide lighting at selected locations.
