A vehicle lighting device includes at least one headlight, a position and/or acceleration sensor, and a control unit for adjusting a light/dark boundary of the headlight. Pitch movements of the vehicle can be detected by the position and/or acceleration sensor, and a change in the light/dark boundary due to the respective pitch movement can be compensated for by the control unit. The position and/or acceleration sensor and the control unit are arranged in the headlight or directly on the headlight.

A headlight system for a banking vehicle is provided. The headlight system includes a plurality of optical assemblies being arranged about an optical horizon and an optical vertical axis. Each of the plurality of optical assemblies includes an illumination source and an optical element. Each of the illumination sources is configured to direct light toward a corresponding one of the optical elements to produce an illumination region. The illumination regions combine to form an illumination pattern that includes at least one illumination region that is radial and is positioned relative an optical origin. The intersection between the optical horizon and the optical vertical axis defines the optical origin.

A method and apparatus for controlling an autonomous vehicle. The method may include: acquiring vehicle traveling environment information; determining an intended traveling state of the autonomous vehicle based on the vehicle traveling environment information; and in response to detecting an interactive operation of a target user for the intended traveling state, generating a traveling state adjustment instruction corresponding to the interactive operation to control the autonomous vehicle to adjust a traveling state.

A control device for a vehicle lamp including an ECU configured to: i) receive a sensor signal and derive a total angle; ii) retain an initial set value of the vehicle posture angle, the initial set value being acquired in an initialization process; iii) retain a reference value of the vehicle posture angle, adjust an optical axis angle of the vehicle lamp in response to a change amount of a total angle during a stop of the vehicle, and retain a sum of the change amount of the total angle and the reference value of the vehicle posture angle as a new reference value; iv) not adjust the optical axis angle in response to a change amount of a total angle during traveling of the vehicle; and v) perform a predetermined reset process when a reset signal is received.

A system to enhance vehicle safety is disclosed comprising a vehicle having a front end and a rear end; at least one visual signal light apparatus positioned in the proximity to the front end of the vehicle; the visual signal light apparatus illuminates when the vehicle's is decelerating via its braking system; wherein the visual light apparatus is comprised of at least a main component and a mount component; wherein the mount component is suitable to mount the main component to a surface of the front of the vehicle; wherein the main component is comprised of a housing, an LED array, and a solar array; wherein the housing is comprised of a recessed portion housing the LED array; wherein the LED array faces the front end of the vehicle; and wherein the solar array is embodied to a top surface of the housing.

A leveling apparatus for a vehicle headlamp includes: a housing disposed at a front side of a vehicle; a light source module disposed in the housing to emit light; a tilting sensor disposed in the housing to detect an inclination degree of a road; a tilting means to tilt the light source module and the tilting sensor together; and a controller. The controller receives a signal detected by the tilting sensor and controls the tilting means based on the inclination degree of the road to adjust a light emission angle of the light source module. In addition, the tilting sensor operates until a sensed output of the tilting sensor reaches a normal range.

A vehicle lamp controller, a vehicle lamp system, and a vehicle lamp control method are provided. The vehicle lamp system includes an acceleration sensor, a vehicle lamp, and the vehicle controller. The controller includes a receiver configured to receive an acceleration information detected by the acceleration sensor, a control unit configured to derive a vehicle longitudinal direction acceleration and a vehicle vertical direction acceleration from the acceleration information, and to generate a control signal for instructing an adjustment of an optical axis of the vehicle lamp, based on a variation in a ratio between a temporal change amount of the vehicle longitudinal direction acceleration and a temporal change amount of the vehicle vertical direction acceleration during at least one of an acceleration and a deceleration of a vehicle, and a transmitter configured to transmit the control signal to an optical axis adjusting portion of the vehicle lamp.

An optical axis control apparatus is provided with a relative-road-surface-angle calculating unit which calculates a relative horizontal plane angle being an inclination angle of a vehicle with respect to a horizontal plane by using an output value of an acceleration sensor provided on the vehicle and calculates a relative road surface angle being an inclination angle of the vehicle with respect to a road surface by integrating an amount of change of the relative horizontal plane angle while the vehicle is stationary, a relative-road-surface-angle correcting unit which obtains braking information indicating an operation state of a brake device provided on the vehicle and corrects the relative road surface angle for a change in the braking information, and an optical axis control unit which controls an optical axis of headlights provided on the vehicle using the relative road surface angle corrected by the relative-road-surface-angle correcting unit.

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.
