A method (100) for reducing headlight glare experienced by a user of a vehicle (10), the vehicle (10) comprising a headlight system (12) having at least one headlight (30, 32) operable to illuminate an environment external to the vehicle, the method (100) comprising: illuminating the environment external to the vehicle; obtaining (102) image data of the illuminated environment; performing (146) a first analysis of brightness values of the image data to identify reflective surfaces that may cause glare; performing (148) a second analysis of brightness values of the image data to categorise the identified reflective surfaces into at least two categories; and adjusting (149) the light output from the at least one headlight (30, 32) in the direction of each identified reflective surface in dependence on the category of that reflective surface.

A vehicle headlight device attached to a part of a vehicle and configured to apply illumination light to a road surface on which the vehicle runs comprises: a light source device configured to Generate the illumination light; an optical unit disposed on a light axis of the light source device and configured to project the illumination light from the light source device so as to form a desired light distribution; and a polarization direction conversion device disposed in a part of a light path between the light source device and the optical unit and being able to control the illumination light from the light source device with inclusion of conversion of a polarization direction thereof for each irradiation region in accordance with a state of a position irradiated with the illumination light on the road surface.

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.

An information processing system includes a vehicle and a server that is able to communicate with the vehicle. The server stores weather information indicating the weather. The vehicle receives the weather information from the server and acquires an image in which a scene outside the vehicle is captured when an operating state of an onboard device is not a prescribed operating state corresponding to the weather indicated by the weather information. The vehicle or the server detects the weather from the image. The server updates the weather information to indicate the weather detected from the image when the weather detected from the image and the weather indicated by the weather information do not match and provides information to a client using the updated weather information.

A vehicle lamp includes: a light source unit including one or more light sources and configured to generate light; a reflector configured to reflect at least part of the light generated by the light source unit; and a lens configured to transmit therethrough a first portion of the light that is generated by the light source unit and that is reflected by the reflector to the lens. The reflector includes: a reflective part configured to reflect, to the lens, the first portion of the light generated by the light source unit; and a non-reflective part configured not to reflect, to the lens, the light generated by the light source unit. The reflective part and the non-reflective part of the reflector are configured to selectively reflect the light generated by the light source unit towards the lens to output a light distribution pattern from the vehicle lamp.

A control device for a headlight for emitting light according to a headlight signal corresponding to an adjustable light distribution. The control device outputs the headlight signal, corresponding to the adjustable light distribution, to the headlight. The control device has an evaluation unit that determines object position data of the object when particles are detected using a detection unit and a self-illuminating object is detected, and to determine, as a function of the object position data, a region in which the object is located. The evaluation unit also generates data for the light distribution as a function of the region in such a way that a light intensity in the region is reduced or increased with respect to a light intensity outside this region, and correspondingly to determine and output the headlight signal from the data for the light distribution.

A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.

A method (100) for reducing headlight glare experienced by a user of a vehicle (10), the vehicle (10) comprising a headlight system (12) having at least one headlight (30, 32) operable to illuminate an environment external to the vehicle, the method (100) comprising: illuminating the environment external to the vehicle; obtaining (102) image data of the illuminated environment; performing (146) a first analysis of brightness values of the image data to identify reflective surfaces that may cause glare; performing (148) a second analysis of brightness values of the image data to categorise the identified reflective surfaces into at least two categories; and adjusting (149) the light output from the at least one headlight (30, 32) in the direction of each identified reflective surface in dependence on the category of that reflective surface.

An adjusting system for a lighting apparatus for vehicles is configured to emit light for forming a light distribution described by a parameter set. The adjusting system includes a light control unit and is configured to modify the light distribution. The parameter set describing the light distribution is stored in the light control unit, which and configured to control the lighting apparatus such that the lighting apparatus emits light for forming the light distribution in accordance with the parameter set into an area in front of the lighting apparatus. An operator control unit separate from both the lighting apparatus and the light control unit is configured to accept user inputs and to transmit the user inputs to the light control unit, which is configured to modify the parameter set in accordance with the user inputs to produce a further parameter set describing a further user-defined, preferably dynamic, light distribution.
