Abstract
The invention is notably directed to a computer-implemented method of detecting obstacles (40) in an area (45) adjacent a vehicle (2) based on low-beam images (32). A low-beam image (32) is an image of a given area, obtained by a camera (223) of the vehicle (2) at night or in low-light conditions while partially illuminating the given area (45) with a low-beam lighting system (236) of the vehicle (2). The method comprises repeatedly performing algorithmic cycles at a processing unit (110) of the vehicle (2). Each cycle comprises: accessing (S311) a low-beam image (32) of an area (45) adjacent the vehicle (2); running (S316) a computational model (50) based on the low-beam image (32) accessed, wherein the computational model is a computer vision model that was trained (S300) based on low-beam images (32) labelled in accordance with potential obstacles therein, for the computational model to detect one or more potential obstacles (40) in the low-beam image (32) accessed; and signalling (S318), in response to an obstacle (40) detected (S317: Yes) in the low-beam image (32) accessed, a control unit (250) of the vehicle (2) to autonomously trigger (S319) a behavioural change of the vehicle (2), such as braking of the vehicle. The model may advantageously rely on IR images obtained while fully illuminating the given area with a high-beam infrared lighting system (234) of the vehicle (2), so as to exploit complementarities between the two types of images. The invention is further directed to related computerized units and computer program products.

The invention relates to a control unit housing for a motor vehicle headlight, the housing comprising a cover (2), a shield (3), a printed circuit board assembly (PCBA) and a heat sink. The shield, interposed between the cover and the PCBA, comprises a set of electrically conductive push elements (28), each push element comprising one or preferably two arms (32, 34) inclined toward the PCBA, the free end (33, 35) of each arm coming into resilient bearing contact with the ground strip of the PCBA when the housing is assembled, these arms being oriented longitudinally relative to the ground strip. The cover preferably comprises rods (21), which, when the housing is assembled, pass through openings (39) in the shield and bear against a base (31) of the push elements so as to press them against the PCBA.

Abstract
The invention relates to a method comprising, on obtaining (500; 501) a first image representative of a scene facing the vehicle, determining (502) a light intensity map, on the basis of a light intensity map generation model and of the first image obtained, the light intensity map indicating light intensity values for controlling lighting elements of a matrix source of the illumination module of the vehicle. The determined light intensity map is transmitted (503) to the illumination module for the projection of a pixelated illuminating light beam onto the scene facing the vehicle. A second image representative of the scene facing the vehicle is obtained following the projection of the pixelated illuminating beam, and an image processing operation is carried out on the second image obtained, the image processing operation being a semantic perception image processing operation.
