A method is provided for operating a motor vehicle (100) having a headlight (1) with a projection module (2). The projection module (2) is moved into a projection position by a motor (3) to regulate a beam width of the headlight (1). The motor (3) is controlled to move the projection module (2) into the projection position and to reach a motor setpoint value. The motor setpoint value is stored in a non-volatile memory (4) of the headlight (1) and, when a voltage supply to the headlight (1) is activated following deactivation of the voltage supply, the projection module (2) is moved, starting from the stored motor setpoint value, into a leaving-home position so as to illuminate an environment adjacent to the motor vehicle (100). A headlight (1) and a motor vehicle (100) also are provided.

An adjustment device is provided for aiming two oppositely pivoted lamp elements. That device includes a single aim adjuster screw, a first connection connecting the adjuster screw to a first lamp element and a second connection connecting the adjuster screw to a second lamp element. One turns the adjuster screw to simultaneously pivot the first and second lamp elements in opposite directions and thereby aim the two lamp elements in a synchronous manner.

The invention relates to a method for calibrating a lighting apparatus, particularly lighting apparatus for a motor vehicle.

A system and method control a vehicular headlamp for preventing a shadow area between a low beam and a high beam of a headlamp using a camera unit. The method includes periodically determining whether a high beam of the vehicular headlamp is lit or illuminated. Upon determining that the high beam is illuminated, the method includes determining whether a darkness cell is formed in front image data of the vehicle, which is transmitted from a camera unit. Upon determining that the darkness cell is formed, the method includes changing a leveling motor to be directed upward by 1 step and storing a changed number of steps. Upon determining that the darkness cell is not formed, the method includes driving the leveling motor by the pre-stored number of steps.

A motor vehicle has a headlight, a first position sensor for outputting first position information, a second position sensor for outputting second position information, and an actuating system which is configured to adjust a light distribution generated by the headlight as a function of the first and second position information.

A method for calibrating a light module including a set of light-emitting elements, the method including powering the light-emitting elements so as to obtain an image projected by the light module, the projected image including a set of pixels, each pixel corresponding to at least one subset of at least one light-emitting element of the light source; for each pixel of the projected image, comparison of a difference between a light intensity of the pixel with a predefined light intensity of a corresponding pixel of a reference image, with a threshold; in the case where the difference is above the predetermined threshold, determination of a modified power supply value of at least one first light-emitting element of the subset corresponding to the given pixel; and storage, in a memory of the light module, of the modified power supply value in association with an identifier of the subset including the first light-emitting element.

A method for controlling forward lighting of a vehicle includes projecting, from a headlamp of the vehicle, an optimization pattern ahead of the vehicle and capturing, by a vehicle sensor, image data of the optimization pattern. The method also includes receiving, by a vehicle controller, the image data of the optimization pattern, measuring, from the image data, a headlamp aim offset defined as a difference in a position of the optimization pattern from a nominal position, and controlling an aim of the headlamp of the vehicle based on the headlamp aim offset.

There is provided an aiming adjustment method for a vehicle headlamp which performs aiming adjustment based on a reference point on a light-dark boundary of a light distribution pattern, the method includes setting, as the reference point, an intersection between a vertical light-dark boundary of a part of multi-divided light distribution patterns which are to be synthesized to form a high-beam light distribution pattern and a horizontal light-dark boundary of a low-beam light distribution pattern.
