Patent ID: 8131501

Claim:
In a change gear transmission, a method for determining a position s of a shifting fork, wherein the shifting fork can be moved from a neutral position N into at least one gear position s GP and wherein a sensor system generates an output signal U correlating to the position s, wherein the sensor system comprises at least one magnet and at least one magnetic field sensor that can be moved relative to the magnet, the method comprising: a. Storing a base diagram for a base output signal U 0 as an indicative value for the position s of the shifting fork; b. Determining a boosting factor V GP in the gear position s GP as a ratio between a base output signal U 0,GP indicative for the at least one gear position s GP and determined from the base diagram and an actual generated output signal U GP that is indicative for the gear position s GP ; c. Determining a function F V for a boosting factor V depending on the position s, wherein a starting value V N of the boosting factor V is assumed in the neutral position N, and a gear position value V GP of the boosting factor V is assumed in the at least one gear position S GP ; d. Determining, by the sensor system, the position s of the shifting fork based on the output signal U, the function F V and the stored base diagram.
