Abstract
An adaptation method for a position detection member, particularly for detection of the position of the throttle valve of an internal combustion engine in a motor vehicle, is suggested, wherein a plurality of position receivers have a common drive and scan a plurality of overlapping path areas with different resolutions. The adaptation is effected in the overlapping path areas. In so doing, a correction value (k.sub.i) is formed, and the measured values (M2) of the path area to be adapted is added to it. A new correction value (K.sub.i+1) is formed in each instance from the differential value (D) between the corrected measured value (W2) of the path area to be adapted and a desired value (T (W1)) for this path area. In so doing, the desired value is taken from an assignment table by means of which measured values (W1) of another path area forming a measurement basis are assigned desired values for the path area to be adapted. A very high accuracy can be achieved by means of this adaptation in spite of low-cost manufacture with relatively high allowable tolerances of the position detection member.
