A vehicle (9) headlight measurement system instrumentation structure (1) comprises: a support structure (3); a vehicle calibration assistance structure (4), which is carried by the support structure (3) and includes a headlight aiming device (40), configured to facilitate alignment or calibration of a headlight (90) of the vehicle (9), the vehicle (9) being positioned within a service area (8); a processing system (11) configured to receive, from the headlight aiming device (40), data correlated with a light beam emitted by the headlight (90) and to provide, through an interface (10), an informative indication relating to an operating condition of the headlight (90), where the processing system (11) includes a communication port (12) connectable to an electronic control unit (91) of the vehicle (9).

A vehicle headlight measurement system instrumentation structure, comprises: a support structure; a vehicle calibration assistance structure, which is carried by the support structure and includes a headlight aiming device; a positioning target element, having a surface provided with a predetermined graphical feature, the positioning target element being supported by the support structure and oriented in a forward direction towards the service area; a positioning device, configured for aiding a relative positioning between the vehicle and the vehicle calibration assistance structure; a processing system which is operatively connected to the positioning device.

A multifunctional unit for the analysis and calibration of devices and components of a vehicle and, in particular, of a motor vehicle (13), comprising a movable trolley (10) of support; above the trolley (10) there is a base (14), which carries a screen or panel (15), at the top of which a video projector (16) is placed, suitable for projection of the calibration panels used in driver assistance systems of vehicles.

A headlamp aiming method for a vehicle includes measuring, by a height measurement instrument, at least two reference heights of at least two reference areas along a body of the vehicle. The height measurement instrument is positioned external of the vehicle, and one of the at least two reference heights is indicative of a height of a headlamp of the vehicle. The method further includes determining a vehicle pitch and a headlamp height variation of the vehicle based on the measured reference heights, calculating a modified headlamp position based on the vehicle pitch, the headlamp height variation, and a standard headlamp position, and aiming a headlamp of the vehicle based on the modified headlamp position.

The present invention relates to a headlight setting test device comprising a lens, which directs an image of the tested headlight on a monitor, comprising a data memory, which stores the height difference between the contact area of a rear wheel arranged on the side of the relevant headlight being tested and the contact area of the corresponding front wheel or a value corresponding to said height difference, and comprising a correction possibilitytaking account of the relevant height difference or valuefor the position of the image on the monitor, as a result of which the effect of the height difference on the assessment of the relevant setting of the relevant headlight is able to be compensated for. The invention furthermore relates to a headlight setting station, a headlight setting device and a method for testing a headlight setting.

The present invention relates to a method for detecting the direction of the orientation of a vehicle, wherein the direction of the orientation of the vehicle is the direction of the axis of symmetry of the vehicle. In this case, the currently imaged vehicle represents its own reference in that, from the photographic image of the front side of the vehicle, a correlation is determined between the parts of the photographic image of the front side of the vehicle that are located in different parts of the photographic image of the front side of the vehicle with respect to an optical axis of symmetry of the front side of the vehicle, wherein the direction of the orientation of the vehicle relative to the imaging direction of the photographic image is derived from the correlation. The detected direction of the orientation of the vehicle can be used in test procedures of vehicle units, which, in terms of the radiation and/or reception direction of beams are to be aligned with the direction of the orientation of the vehicle or its geometrical axis of travel. The evaluation can be effected both with a photographic image of the front side of the vehicle, as well as also with a photographic image of the rear side of the vehicle.

The present disclosure discusses a lighting apparatus. The lighting apparatus includes a housing with a fastening fixture and a pivot fixture, a light bar including a first arm, a second arm and a third arm with an optical marking, and a light guide including a light pipe, a pivot hole, a first slot and a second slot located between the housing and the light bar, wherein the optical marking of the light bar is aligned with the light pipe of the light guide by rotating the light guide and the first arm about the pivot hole and the light bar is fastened to the housing.

An ADAS calibration system for calibrating at least one headlamp of a vehicle. The ADAS calibration system including a support; optical measurement device mounted on the support for detecting the distances of two front or rear wheels of the vehicle from the support; a projection surface mounted on the support; and at least one headlamp beam setter. The headlamp beam setter includes a screen configured to show a pattern created by the two-dimensional projection of the light beam emitted by the headlamp and a camera configured to acquire images of the pattern shown on the screen. The ADAS calibration system also includes a control unit configured to receive from the optical measurement device the distances detected and from the camera the images of the pattern and, in response to them, to compute an alignment angle for the headlamp.
