A light system may be provided for a vehicle. The light system may include a light source for signaling a surrounding vehicle, a communication device for communicating with the surrounding vehicle, and a controller coupled to the light source and the communication device. The communication device may receive a vehicle information message from the surrounding vehicle. Based on the vehicle information message, the controller may determine at least one of a velocity and an acceleration rate of the surrounding vehicle, analyze the at least one of the velocity and the acceleration rate to determine a default state or an impact condition, and when the impact condition is determined, automatically activate the light source to signal the surrounding vehicle.

To obtain projection images with high contrast when selective light irradiation is performed forward of its own vehicle. A lamp unit for a vehicular lamp system performing selective light irradiation to the surroundings of the own vehicle includes: a light source; an optical shutter part that modulates light emitted from the light source; and an optical system that projects the light transmitted through the optical shutter part. The optical shutter part includes: polarizers; a liquid crystal element disposed between the polarizers and where the initial alignment of liquid crystal molecules is horizontally aligned and causes an alignment change in the in-plane direction upon electric field application; a first optical plate which is a positive A-plate disposed between the polarizers closer to the light source and the liquid crystal element; and a second optical plate which is a positive C-plate disposed between the first optical plate and the liquid crystal element.

An invention is a saddle type vehicle comprising a lighting device, and an operator configured to perform a driving operation of a direction indicator, characterized in that the lighting device is configured to irradiate a part of a road surface on a front to lateral side of the saddle type vehicle in accordance with input of an operation of showing an intention of route change to the operator by a driver of the saddle type vehicle.

A light distribution control apparatus comprises an irradiating apparatus and an irradiation control apparatus. When a vehicle is travelling on an own lane, the irradiation control apparatus lightens a first region including a region right in front of the vehicle using the irradiating apparatus. When a request for lane change to a target lane occurs under a situation where the vehicle is travelling on the own lane, the irradiation control apparatus lightens a second region using the irradiating apparatus, the second region including a region-at-a-lane-change-side positioned at a target lane side with respect to the first region and a reduced region which is a region where the first region is reduced to a region near the vehicle as well as control the irradiating apparatus so that illuminance in the reduced region becomes less than or equal to illuminance in the reduced region before the request for lane change occurs.

Information related to a vehicle can be displayed by projecting an image based on the information on a road surface or the like. An image projection apparatus that projects an image includes: a sensor unit that acquires information related to a vehicle; and an image projection unit that projects the image based on the information acquired by the sensor unit.

An exterior rearview system for an autonomous vehicle includes a housing adapted for mounting to an exterior side of a vehicle, the housing holding at least one of a reflective element or display screen for displaying to a driver a rear or side image of the vehicle, one or more lighting modules disposed in the housing and providing an adaptive lighting sector which is adaptively controlled, and a control system configured to receive input data related to at least one of a user's intention using a tracking sensor and a user's retaking control of the autonomous vehicle.

A rear lamp includes a reverse light, a direction indicator light, a brake light and a taillight, which are provided inside a lamp case. The rear lamp includes left and right rear lamps and has a peripheral area and a center area. The peripheral area is disposed on the outer side of the center area. The reverse light, the brake right and the taillight are positioned in the center area. The direction indicator light is positioned in the peripheral area and is formed as an LED array in the shape of a C or inverted-U. The left rear lamp has a U-turn indicator light and a left turn indicator light. The right rear lamp has a right turn indicator light. When the U-turn indicator light activates, the entire LED array turns on. When the left turn indicator light activates, only a part of the LED array turns on.

Device for controlling at least a first light source of a motor vehicle, the motor vehicle at least comprising the first light source being configured to provide a first light function and a second light source configured to provide a second light function, the device comprising: electrical means configured to detect activation of the second light source, and to deactivate the first light source after detection of activation of the second light source. Also, method for controlling at least a first light source of a motor vehicle, the motor vehicle comprising the first light source being configured to provide a first light function and a second light source configured to provide a second light function, the method comprising: electrically detecting activation of the second light source; and electrically deactivating the first light source after detecting activation of the second light source.

An image projection apparatus that can be attached to a vehicle and can be effectively utilized for acquisition of road surface condition information, detection of a hidden vehicle, and the like is provided. The image projection apparatus that projects an image includes: an acquisition unit that acquires information related to a vehicle; an image projection unit that projects an image based on the information acquired by the acquisition unit; and imaging means that acquires an image outside the vehicle, the image projection unit projects light in a wavelength band centered on a wavelength of 1.4 m and the imaging means provides the information related to the vehicle by imaging an image projected based on the light in the wavelength band centered on the wavelength of 1.4 m.
