Shifting device of a vehicle transmission

A shifting device of a vehicle transmission, comprising:

• a dog clutch with two positive-locking shifting element halves connectable to each other, wherein a positive connection between the shifting element halves is established or released through a relative translational movement between the shifting element halves between a first operating state in which the positive connection is established and a second operating state in which the positive connection is separated, the shifting element halves rotatable about a direction of relative movement between the shifting element halves;
• a sensor device comprising a permanent magnet and a measuring device disposed to sense a magnetic field of the permanent magnet;
• a ferromagnetic encoder contour that influences the magnetic field of the permanent magnet as a function of the first and second operating states of the shifting element halves, the encoder contour comprising two surface areas that adjoin each other in a joint area, the encoder contour fixed relative to one of the shifting element halves such that the encoder contour is rotatable about the direction of relative movement, the encoder contour being circumferentially symmetrical about the direction of relative movement;
• the surface areas of the encoder contour formed in a convex or concave manner between opposite end areas relative to the measuring device such that a perpendicular gap is established between the surface areas of the encoder contour and the permanent magnet that, starting from the joint area, increases or decreases in a direction towards the end areas;
• and
• wherein relative movement between the shifting element halves is guided translationally through the magnetic field of the permanent magnet such that the magnetic field sensed by the sensor device monotonically increases or monotonically decreases as a function of axial change of position of the joint area of the encoder surface areas relative to the sensor device, the sensor device configured to output a signal indicative of a current operating state of the shifting element halves based upon the magnetic field sensed by the sensor device.
