摘要： A light-distribution control apparatus includes a light-distribution changer configured to change distribution of light that a headlamp of the vehicle emits toward a region in front of the vehicle, a data acquirer, an attitude sensor, and a brake sensor, a light-distribution control processor. The light-distribution control is configured to control the light-distribution changer based on one or more pieces of the data acquired from the data acquirer, the attitude data acquired from the attitude sensor, and the internal pressure data acquired from the brake sensor. The light-distribution control processor is configured to control the light-distribution changer based on the internal pressure data.

摘要： 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.

摘要： A vehicle lighting-based roadway obstacle notification for a motor vehicle has a vehicle headlamp system with a controllable light distribution. A camera is aligned parallel to a forward driving direction records a part of the roadway surface lying in front of the motor vehicle which includes a multiplicity of roadway detection paths. Camera data are individually evaluated in relation to ranges and at least one quantity from among a magnitude of a vertical dimension hi of the roadway, a magnitude of a gradient gradx;i of the roadway, and an instantaneous speed vmom of the motor vehicle, with respect to the roadway detection paths. When at least one predetermined condition in respect of at least one of these quantities is complied with, the vehicle headlamp system is controlled in order to illuminate a part of the width of the roadway in which a roadway anomaly has been detected.

摘要： A method for adjusting a distribution of light from a headlight of a first motor vehicle in order to avoid the headlight blinding of dazzling a driver of a leading vehicle travelling ahead of and in the same direction as the first vehicle. The method includes: detecting a following distance between the vehicle and the leading vehicle on an initial road section; operating the headlight at a first illumination range less than or equal to the following distance; detecting a directionally-deviating road section ahead of and having a direction different from the initial road section; detecting that the leading vehicle has moved beyond a transition between the initial road section and the directionally-deviating road section; operating the headlight at a second illumination range not extending beyond the transition; and operating the headlight at the first illumination range after the vehicle reaches the transition.

摘要： A control device may include a sensing unit configured to sense a topographical state of a road surface on which a vehicle is travelling. The control device may also include at least one processor configured to, based on the topographical state of the road surface being a first topographical state, control a head lamp of the vehicle to be in a first output state that outputs light to a first area ahead of the vehicle. The at least one processor may also be configured to, based on the topographical state of the road surface changing to a second topographical state different from the first topographical state, control the head lamp of the vehicle to change to a second output state that maintains the output of the light to the first area ahead of the vehicle.
