Claim 12:
13. 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 exited an inner tolerance range (ΔxS_T) at a beginning (t1) of an observation period (ΔtB),
detecting, at a time when a shift request has occurred after the beginning of the observation period, that the sensor signal (xS2(t)) of at least one signal receiver (60) has exited an outer interference range (ΔxS_S), which range is greater than the inner interference range, within the observation period (ΔtB), and
in response thereto, determining that a magnetic interference field that is detrimental critical relative to a proper functioning of the shifting device (2) is not present but the sensor signal (xS2(t)) of at least one signal receiver (60) has exited the interference range (ΔxS_S) within the observation period (ΔtB) due to a shift request that has occurred in the meantime.
