Claim 0:
1. A sensor arrangement (46) for an automated transmission, comprising:
a shifting device (2) including multiple shift rails (4, 14, 24, 34), which are arranged so as to be axially parallel to one another and which are axially displaceable by associated shift actuators (8, 18, 28, 38),
wherein the sensor arrangement (46) includes multiple displacement sensors (48, 56, 64, 72),
wherein each of the displacement sensors comprises a signal transmitter (50, 58, 66, 74) attached to one of the shift rails (4, 14, 24, 34) and a signal receiver (52, 60, 68, 76) fixedly arranged on a housing,
wherein the signal transmitters (50, 58, 66, 74) are each in the form of a permanent magnet having magnetic poles,
wherein the signal receivers (52, 60, 68, 76) are each in the form of a 3D Hall sensor, and
wherein the signal receivers (52, 60, 68, 76) are each connected to an electronic transmission control unit (44) via electrical sensor lines (54, 62, 70, 78),
wherein the signal transmitters (50, 58, 66, 74) are arranged having an identical axial alignment of their magnetic poles (N, S), and
wherein the signal receivers (52, 60, 68, 76) are arranged in a common plane (80) that is horizontal in an installation position of the signal receivers;
wherein the electronic control unit receives signal values from the signal transmitters during an observation period, wherein the electronic control unit receives data corresponding to whether a gear change operation has been triggered during the observation period.
