A vehicle lighting system is provided in a vehicle capable of traveling in an automated driving mode. The vehicle lighting system includes an automated driving system (ADS) lamp configured to emit light toward an outside of the vehicle to visually present information relating to automated driving of the vehicle, and a lighting control unit configured to determine brightness of the ADS lamp according to at least one of a distance between an object outside the vehicle and the vehicle, an attribute of the object, and a road surface condition around the vehicle.

The invention describes an illuminant for a vehicle headlight comprising a carrier and an electrical driver. Mounted on the carrier are a high-beam LED, a low-beam LED and a vehicle light detector. Additionally, a mechanical interface is included for mounting the illuminant in a corresponding socket of the vehicle headlight in a detachable way, and an electrical connector for supplying electrical power to the electrical driver. The electrical driver is arranged to receive vehicle light detection signals from the vehicle light detector to determine vehicle light by means of the vehicle light detection signals, and to provide a drive current to the high-beam LED or the low-beam LED depending on the determined vehicle light. Illuminant is further arranged to detect ambient light other than the vehicle light, such detection of ambient light influencing electrical driver in controlling the LEDs.

There is provided a lighting device arranged to produce a controllable light beam for illuminating a scene. The device comprises an addressable spatial light modulator arranged to provide a selectable phase delay distribution to a beam of incident light. The device further comprises Fourier optics arranged to receive phase-modulated light from the spatial light modulator and form a light distribution. The device further comprises projection optics arranged to project the light distribution to form a pattern of illumination as said controllable light beam.

A system and method to control headlights of a vehicle includes receiving a broadcast that indicates a location of a sending device of the broadcast. The method also includes obtaining other information that indicates at least one of a weather condition or an ambient lighting condition, and analyzing the broadcast and the other information to determine whether the headlights should be enabled or whether high beams of the headlights should be enabled. The method further includes generating a signal to control the headlights according to the analysis.

A vehicle lamp control device includes an information acquisition unit that acquires snowfall information, and a controller that controls a vehicle lamp capable of changing a formation position of a light distribution pattern. The controller controls the vehicle lamp so as to lower the formation position from a predetermined reference position when snowfall is perceived, and when the snowfall amount is larger than a predetermined value, the controller substantially lowers the formation position as compared with the formation position when the snowfall amount is smaller than the predetermined value.

A headlight control system controls a headlight of a moving object. The moving object includes the headlight including a plurality of light emission units, and an imaging unit configured to capture images of circumstances in front. The headlight control system includes an irradiation pattern controller configured to perform control for changing at least one of presence or absence of light emission and a degree of light emission of each of the light emission units to change an irradiation pattern of the headlight to one of a plurality of irradiation patterns, an imaging controller configured to perform control such that the imaging unit captures the images of the circumstances in front for each of the irradiation patterns to acquire captured images, and a learning unit configured to learn an irradiation pattern suitable for the circumstances in front based on captured images captured for each of the irradiation patterns.

A method and system for controlling exterior lights on a vehicle. The method includes receiving an input indicative of a desired mode of operation of the exterior lights from a user-selectable input device. The user-selectable input device includes an on-setting, an off-setting, and an automatic-setting. The method further includes receiving sensor data indicative of a level of visibility outside the vehicle, comparing the sensor data to a threshold, and generating, by an electronic processor, a notification indicative of an improper positioning of the user-selectable input device when the sensor data indicates that the level of visibility is less than the threshold and the user-selectable input device is positioned in the off-setting.

A vehicle headlight control apparatus controls headlights of a vehicle including LEDs. The vehicle headlight control apparatus includes: drivers and each of which gradually changes a luminance of the LEDs between a predetermined on state and a predetermined off state over a switching time period; and a lamp ECU that determines the switching time period in a changeable manner.

A fog detecting system for a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle, and a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle. The camera captures image data and the non-imaging sensor captures sensor data. A control includes at least one data processor operable to process image data captured by the camera and sensor data captured by the non-imaging sensor. The control, responsive to processing of image data captured by the camera and processing of sensor data captured by the non-imaging sensor, determines presence of fog ahead of the vehicle and in the field of view of the camera and in the field of sensing of the non-imaging sensor.

A headlight device is a headlight device for a vehicle, including a light source unit to include a plurality of light-emitting units respectively emitting light having spectral distributions different from each other and to emit illuminating light having a combined spectral distribution as a combination of the spectral distributions of the plurality of light-emitting units, an acquisition unit to acquire environment information indicating a surrounding environment around an illumination region formed by the headlight device, and a control unit to control the spectral distributions of the plurality of light-emitting units based on the environment information acquired by the acquisition unit.
