Abstract: A method for adjusting and/or calibrating a surroundings sensor in a vehicle using a measuring unit and a calibration panel.

Abstract: A calibration frame for calibrating a reference system for vehicle measurement has setting elements, which enable a precise spatial orientation of the calibration frame, and multiple defined points of support, which are designed to accommodate a reference system carrier. In one specific embodiment, the points of support are designed in such a way that the reference system carrier is situatable on the points of support in at least two different orientations. In a second specific embodiment, a leveling element is provided which indicates the spatial orientation of the calibration frame in relation to the earth's gravitation field.

Abstract: A method and a device are provided for the optical axle alignment of wheels of a motor vehicle. At the wheels that are to be aligned, targets are mounted, having optically recordable marks, the targets being recordable by measuring units that have stereo camera devices. In a referencing process, using a referencing device that is integrated into the measuring units, a measuring position reference system is established for the measuring units. In a calibration process, in which a local 3D coordinate system is established using at least three marks of the target, the determination of a reference plane is carried out, using a significant mark of the target. Finally, using the reference plane, a vehicle longitudinal center plane is ascertained, while taking into account the measuring location reference system.

Abstract: A method according to the invention for adjusting or calibrating a vehicle surroundings sensor (15) comprises the steps of: attaching at least one target pair (20, 22) to the rear wheels (12, 14) of the motor vehicle (7); recording the target pair (20, 22) using at least one measuring unit (32, 46) and determining the vehicle axle (64) from the recording; placing at least one target (16, 18) in a known position relative to a vehicle surroundings sensor adjustment or calibration element (62); recording the target (18) placed at the vehicle surroundings sensor adjustment or calibration element (62) using the at least one measuring unit (32, 46) and determining the angular position of the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axle (64); aligning the vehicle surroundings sensor adjustment or calibration element (62) relative to the vehicle axis (64); and adjusting or calibrating the vehicle surroundings sensor (15) relative to the vehicle axis (64).
