Abstract: In a method for measuring the wing edge of a vehicle on a test bed, the test bed has a coordinate system in which the Z-axis is the vertical axis, the X-axis is an axis on the test bed extending in the horizontal plane in the longitudinal direction of a vehicle located on the test bed for testing, and the Y-axis is an axis of the test bed extending perpendicular to the X-axis in the horizontal plane. In determining the position and orientation of the wing edge, a light pattern projected onto a vehicle by an illumination unit is moved and recorded by two imaging units. A subset for evaluation is formed from the 3D point clouds determined stereophotogrammetrically from the recordings.

Abstract: The present invention relates to a vehicle test bench for calibrating and/or testing systems of a vehicle which comprise at least one camera. The vehicle test bench has a target position for the vehicle. At least one surface that reproduces an image display and/or shows an image display is assigned to the cameras of systems to be tested. A plurality of elements that absorb stray light are provided, which elements each consist of a wall-like boundary of the vehicle test bench, which reduces penetration of light into the vehicle test bench. A plurality of wall-like boundaries results in lateral delimitation of the vehicle test bench on all sides.

Abstract: This invention relates to a procedure for assessing a signal representing the manual actuating force acting on an adjusting tool for the electrical, pneumatic and/or hydraulic actuation of adjusting means which, at least in the operational state in which the adjusting tool interacts with the adjusting means, serve for the alignment of units and/or sensors of a vehicle. According to this invention, the adjusting tool's drive is blocked if the manual actuating force exceeds a threshold value and/or if a measuring signal representing the alignment of the unit and/or of the sensor is assessed as incorrect and not allowed and/or a signal indicating an error status is generated.
