Abstract: The invention is related to a method for managing a light pattern and an automotive lighting device (10). The method comprises the steps of projecting an original light pattern, providing a reach distance between a retroreflective object (4, 5) and the automotive lighting device, estimating a reach time before the automotive lighting device reaches the retroreflective object (4, 5) and using the reach time to decide whether to activate a light pattern management functionality. If the light pattern management functionality is activated, using an image provided by an image sensor (1) in real time to decide the location of a mask. If the light pattern management functionality is activated, calculating an optimum light pattern for the mask and modifying the original light pattern including the mask with the optimum light pattern.

Abstract: A method for controlling a lighting system of a host motor vehicle with a plurality of selectively controllable elementary light sources, each able to emit an elementary light beam with the vertical angular opening of which is less than 1°. The method includes detecting a target object by a sensor system. Determining a vertical angle between a given point of the sensor system of the host vehicle and a detected point of the target object. Determining, from the vertical angle, a lower angle and an upper angle between a given point of the lighting system and, respectively, an upper cut-off and a lower cut-off intended to together vertically border the target object. Controlling the elementary light sources to emit a pixelated road light beam, as a function of the lower and upper angles, to generate, in the light beam, a dark area extending substantially between the upper and lower cut-offs.

Abstract: Method for controlling a lighting system with the lighting system including a plurality of light sources, wherein each light source is capable of emitting an elementary light beam with the vertical angular aperture of which is less than 1°. The method includes detecting a target object, determining a relative distance between a given point of the host vehicle sensor system and a detected point of the target object and determining a gradient of the road on which the target object is located, determining a lower angle and an upper angle between a given point of the host vehicle lighting system and a high cut-off point and a low cut-off point, controlling the light sources of the host vehicle lighting system in order to emit a pixelated light beam of the driving beam type in order to generate a dark zone extending substantially between the high and low cut-off points.

Abstract: A method for controlling a lighting system of a motor vehicle, the lighting system with a plurality of elementary light sources each selectively controllable in order to emit an elementary light beam, the method includes detecting a road sign by a sensor system of the motor vehicle; estimating a passing duration between the instant the road sign is detected and a future instant at which the motor vehicle will pass the detected road sign; controlling the elementary light sources of the lighting system of the host vehicle in order to emit a pixelated light beam, with a portion of the elementary light sources being controlled, as a function of the passing duration, in order to generate a lower intensity zone extending in the vicinity of the road sign.

Abstract: A method for preventing a collision between a motor vehicle and at least one target object, the motor vehicle includes a detection system capable of detecting the target object and a warning system including at least one light module. The method includes detecting the target object and determining a position and a speed of the target object using the detection system. The method further includes estimating a critical trajectory likely to be followed by the target object in order to collide with the vehicle depending on the position and the speed of the target object, the critical trajectory being associated with a collision risk/collision time relationship. The method additional includes transmitting at least one light warning to the driver of the vehicle using the light module of the warning system.
