Process, device and computer program for simulation of a locking wedge

A method for detecting a gap size and / or an offset between a flap (2) of a motor vehicle and the remaining body (3) of the motor vehicle, wherein the method is performed prior to a painting and before any final assembly of the bodywork (3) of the motor vehicle, characterized that the flap (2) is brought within the framework of a closing wedge simulation in a closed position flush relative to the remaining body (3) of the motor vehicle in front of the sensing of the gap size and / or the displacement, wherein the closing wedge simulation: - Actual values ​​(21_ist) for the offset between the flap (2) and the remaining body (3) are optically detected; - Depending on the detected actual values ​​(21_ist) and of predeterminable, the flush closed position of the flap (2) corresponding desired values ​​(21_soll) for the offset drive signals (24) for at least one in the sense of varying the position and orientation of the flap (2) relative to the body (3) on the flap (2) acting actuator (12) generated ...
