A headlight control system has a headlight including a plurality of LED light sources, a camera and a radar that detect a predetermined target object present ahead of a vehicle, and a controller configured to control the headlight such that, when the target object is present, of the plurality of LED light sources, the LED light source irradiating a region where the target object is present is turned off, and such that, thereafter, when the target object is no longer present in the region, the turned-off LED light source is turned on again. The controller controls the headlight such that, at the time of turning on the turned-off LED light source again, a change rate of luminance of the LED light source is changed according to a position of an irradiation region of the LED light source.

A control method according to the present disclosure includes: obtaining (receiving) position information (a danger warning signal) indicating a target position where a target object is present; determining whether the vehicle is driving autonomously or is being driven manually; when the vehicle is determined to be being driven manually, inspecting whether the target position is located within a predetermined region of a travel route of the vehicle based on the position information; when the target position is located within the predetermined region, changing the light transmission state of the headlight from a first state to a second state; and when the vehicle is determined to be driving autonomously and/or the target position is not located within the predetermined region, maintaining the light transmission state of the headlight.

A lighting control system for a vehicle includes a controller configured to be disposed at a vehicle so as to connect with or communicate with at least one light of the vehicle. The controller, responsive to at least one input, adjusts a color of the at least one light of the vehicle and an intensity of the at least one light of the vehicle. The input may include one or more of (i) a driver attentiveness input and (ii) a driver age input, and optionally a time of day input, an ambient light input, a weather condition input, and/or a navigation input.

A headlight control device provided in a vehicle to perform headlight control and to control a distribution of light irradiated from a light source is provided. The headlight control device includes: a determination unit that determines a presence and an absence of an obstacle in front of the vehicle and determines a position of the obstacle; a setting unit that sets up an area covering the obstacle as an intensified illumination area when the determination unit determines the presence of the obstacle, wherein the intensified illumination area is an area to which the light from the light source is irradiated in a manner different than a peripheral area of the intensified illumination area; and a controller that controls the distribution of the light irradiated from the light source so that the intensified illumination area set up by the setting unit has an illuminated zone and a non-illuminated zone.

The invention describes a method of providing an illumination pattern for vehicle lighting, the method comprising the steps of: providing a light pattern comprising a multitude of scanlines of white light by illuminating a light converter by means of a scanning laser arrangement for illuminating an area, wherein the scanlines are characterized by a defined scanline width; adapting a cut-off of the light pattern by changing a position of at least one scanline with respect to a reference illumination pattern or by dimming at least a limited portion of at least one scanline. The invention further describes a vehicle headlight system and a computer program product.

A motor vehicle includes headlamps having a plurality of LED light sources, one or more processors, and a memory storing instructions. One or more processors executing the instructions are enabled to receive first data, including at least map data, indicating a road curvature upcoming along a road on which the motor vehicle is traveling. The processors are also enabled to determine a light change, the change adapting a light pattern of the headlamps in at least one of color, intensity or spatial distribution to increase light in a direction of the road curvature ahead of the motor vehicle and shaping light based at least in part on the road curvature. The processors are further enabled to control at least a first plurality of the LED light sources to provide light based at least in part on the determined light change and prior to the motor vehicle reaching the road curvature.

Reliability of an in-vehicle headlight is improved by changing a light distribution pattern without using any mechanical configuration. The in-vehicle headlight includes a laser light source, a spatial light modulator, a spatial-light-modulator controller, and a projection lens. The laser light source emits a laser light beam. The spatial light modulator modulates a phase distribution of the laser light beam emitted by the laser light source. The spatial-light-modulator controller is provided in a headlight controller, and controls the spatial light modulator. The spatial-light-modulator controller controls the spatial light modulator so as to modulate the phase distribution of the laser light beam, and changes the light distribution pattern projected from the projection lens.

A vehicular control system includes a camera disposed at an in-cabin side of a windshield of a vehicle, the camera viewing forward of the vehicle through the windshield, and the camera capturing image data representative of at least an upcoming road surface of a road ahead of the vehicle. The vehicular control system, via processing at an image processor of image data captured by the camera, determines traction condition of at least a portion of the imaged upcoming road surface that is ahead of the vehicle. The vehicular control system, via processing at the image processor of captured image data, determines a change in traction condition ahead of the vehicle and adjusts an adaptive cruise control system of the vehicle responsive at least in part to the determined change in traction condition ahead of the vehicle.

A headlight control device which recognizes an oncoming vehicle using a camera without dazzling the driver of the oncoming vehicle includes a sequence control section that generates a headlight control signal from an image captured by the camera mounted on the vehicle, and a control value calculation section that calculates a control value for a light distribution pattern in the headlight control signal. An image recognition program includes a license plate recognition section that detects a license plate of the preceding vehicle from the image, and a cut-off line recognition section that detects a cut-off line of the headlight from the image. The control value calculation section calculates the control value for the light distribution pattern such that the cut-off line detected by the cut-off line recognition section is positioned higher by a predetermined height than an upper end of the license plate detected by the license plate recognition section.

An automotive lamp includes a variable light distribution lamp and a controller. When a first light distribution pattern is to be changed to a second light distribution pattern, and when a difference in the number of shaded portions between the first light distribution pattern and the second light distribution pattern is one, the controller switches a control method for gradually changing the light distribution pattern according to a position relation between the shaded portions included in the first light distribution pattern and the shaded portions included in the second light distribution pattern.
