Methods and apparatus to determine a load pitch angle for headlamp adjustment are disclosed. A disclosed example method for determining a load pitch angle of a vehicle includes determining a first averaged pitch angle corresponding to a first set of pitch angles determined for a first time interval, determining whether a change in a load of the vehicle has occurred during the first time interval based on at least one parameter indicating a change in the load of the vehicle, determining, in response to the change of the load of the vehicle occurring during the first time interval, a second averaged pitch angle corresponding to a second set of pitch angles determined for a second time interval, wherein a start of the second time interval corresponds to a time at which the change in the load of the vehicle occurred, calculating the load pitch angle based on the second averaged pitch angle, and adjusting a position of a headlamp of the vehicle based on the load pitch angle.

A method for adjusting a beam height of at least one headlamp of a vehicle. The steps include determining a setting position of at least one headlamp, the load pitch angle of the vehicle and the dynamic pitch angle of the vehicle by detecting signals by using at least one acceleration sensor, and detecting the operating state of the trailer coupling. If it is detected that a trailer is coupled to the vehicle, determining the dynamic pitch angle based on detected signals for determining the dynamic pitch angle and at least one correction parameter that represents an influence of the trailer on the dynamic pitch angle of the vehicle, determining a deviation of the pitch angle of the vehicle from the setting position and thus a resulting deviation of at least one headlamp from the setting position and adjusting the setting of at least one headlamp.

A lamp aiming method is implemented in an electronic lamp aiming system for a vehicle. In the system and method, a controller recognizes a light distribution area using information of a target in top/bottom/left/right angles in a front image of an image receiver for the target, which is light-distributed to a light source of a head lamp. Another controller adjusts a pixel area of the light source based on the light distribution area to perform aiming correction and to apply the adjusted pixel area to the light distribution of the lamp. Through an electronic aiming structure not using head lamp aiming instruments, direct matching is achieved between the head lamp and a camera, which is required for high-precision aiming. A vehicle attitude can also be determined without sensors by using the secured matching.

The invention discloses a projector unit comprising a housing on which a light module is supported to be pivotable in two spatial directions. Via eccentrics which are supported on the housing, the light module can be rotated in two axes of rotation each having a specific angle of rotation. Preferably, via one eccentric, the light module is pivoted along with the axis of rotation and, via the further eccentric, the light module is rotated about the axis of rotation.

A headlight is provided for a motor vehicle. The headlight includes: a light module, which includes a cornering light or illuminated lettering; an environment sensing element, which includes an optical environment sensor, a radar, or a camera; a housing; and a changing device. The housing has a region into which the light module or the environment sensing element is displaceable, and the changing device is configured to carry out a change between the light module and the environment sensing element in the region.

A vehicle with a road surface rendering function includes a projection member and a controller. The projection member is configured to perform light projection for road surface rendering to a road surface at least forward from the vehicle. The controller is configured to control the light projection for the road surface rendering by the projection member. The controller is configured to, when the vehicle is traveling along a curved road, adjust a road surface rendering image to be rendered on the road surface by projecting light from the projection member to move the road surface rendering image from a reference rendering position in front of the vehicle when the vehicle is traveling along a straight road toward an inside of a curve of the curved road.
