Abstract
A method for determining and specifying necessary closing speed of a motor-operated vehicle door at the moment of reaching an initial closure detent by means of a control unit is described. The motor current of the door motor is determined and compared with a calculated maximum current, wherein the maximum current results from a motor armature resistance measured at the start of the door movement, from a minimum supply voltage of the control unit and from an adjustable factor. If the determined current is higher than the maximum current, the value of an adaptation table is changed and a higher closing speed is specified by the control unit for the next closing movement of the vehicle door; and, if the determined current is lower than the maximum current, a lower closing speed is specified by the control unit for the next closing movement of the vehicle door.
