Claim 11:
12. The method as claimed in claim 9, further comprising:
detecting, at a time when a gear change operation of the transmission has not been triggered, that the sensor signals (xS1(t), xS2(t), xS3(t), xS4(t)) of all signal receivers (52, 60, 68, 76) have exceeded or fallen below an inner tolerance range (ΔxS_T) at a beginning (t1) of an observation period (ΔtB) and, thereafter, have remained within an outer interference range (ΔxS_S), which range is greater than the inner interference range,
detecting that the sensor signal (xS2(t)) of at least one signal receiver (60) has re-entered the inner tolerance range (ΔxS_T) within the observation period (ΔtB), and
in response thereto, determining that a magnetic interference field that is detrimental relative to a proper functioning of the shifting device (2) is not present.
