A first position detection arrangement for a functional element ( 1 ) which can be positioned by a motor in a motor vehicle, a drive arrangement ( 2 ) being coupled via a drive train ( 3 ) to the functional element ( 1 ) and the functional element ( 1 ) thus being positionable by a motor, there being two incremental rotary transducers ( 4, 5 ) which are assigned to the drive train ( 3 ) and there being a control ( 6 ) which is coupled to the rotary transducers ( 4, 5 ). It is suggested that the arrangement is made such that, when the functional element ( 1 ) is being positioned, an offset arises between the rotary transducer signals of the two rotary transducers ( 4, 5 ), the control means ( 6 ) being designed such that it determines the absolute position of the functional element ( 1 ) from the offset.
