Abstract
In a method for tolerance compensation of a position signal (W) of a position transducer, which has two mechanical end stops, first and second end values (W1, W2) of the position signal that are assigned to the two end stops and are stored in a read-write memory. Starting values (W1S, W2S) are stored in a read-write memory of the evaluation circuit and are set within the tolerance limits of the actual signal (Wd) detected by the position transducer. The starting values (W1S, W2S) are initially taken over as the ned values (W1, W2) into a read-write memory and cyclically compared with the actual or detected position signal (Wd). If a stored end value (W2) is exceeded by the detected position signal (Wd) or if within a predetermined time period (P) no position signal above the stored end value (W2) has been detected, the position signal is taken over as a new end value (W2) into the read-write memory, and the previous value is erased. The position signal is referred to a reference value ascertained from the two end values (W1, W2) and converted into a standardized output position signal (U).
