A vehicle posture calculation device includes an electronic control unit for a vehicle. The electronic control unit acquires a position and orientation of the vehicle from information of a global positioning system receiver. The electronic control unit extracts, as at least one feature point, a position of a landmark in an image acquired with a camera. The electronic control unit acquires at least one calculated reference point and calculate an inclination angle of the vehicle. The at least one calculated reference point is acquired by calculating a position of the landmark to be captured in the image with the camera. The position of the landmark is calculated from a three-dimensional map and the position and the orientation of the vehicle that are acquired. The inclination angle is calculated from displacement between the at least one feature point and the at least one calculated reference point.

A headlight horizontal lighting pattern adjustment system includes an inclination angle sensor connected to a vehicle to sense an inclination angle value of the vehicle. A processing unit receives the inclination angle value and processes the inclination angle value into a driving value. A driving module drives a lighting device. The driving module commands the driving device to driving and rotate the lighting device according the driving value. The headlight horizontal lighting pattern adjustment system is equipped to a motorbike or an electric motorbike. When the motorbike turns and tilt, the processing unit adjusts the light of the lighting device by the driving module and the driving device to eliminate dark corners in the dark zone and maintains the full scale of light pattern to enhance safety to all the road users.

An apparatus and a method correct a level of a headlamp, in which a sight of the driver may be sufficiently secured while an influence on a sight of a driver of a preceding vehicle is minimized by specifying a level of a cutoff line of the headlamp using a transverse length and a longitudinal length of a number plate frame image. The specified level is compared with a level of a target line calculated based on a change of an inter-vehicle distance. The method includes determining whether it is necessary to perform a correction of raising or lowering the level of the headlamp, and a correcting the level of the headlamp such that the cutoff line of the headlamp follows the level of the target line at the corresponding inter-vehicle distance.

A method for operating adjustable headlights of a vehicle, the method may include sensing, by a vehicle night-vision sensor, an environment of the vehicle to provide sensed information; searching, in the sensed information, for a headlight adjustment event identifier, the headlight adjustment event identifier identifies a future occurrence of a headlight adjustment event, the headlight adjustment event requires an adjustment of a lighting pattern formed by at least one of the adjustable highlights of the vehicle; and when finding the headlight adjustment event identifier then adjusting the lighting pattern according to the headlight adjustment event, wherein the adjusting begins before the future occurrence of the headlight adjustment event or immediately at a beginning of the headlight adjustment event.

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.
