Patent ID: 8662744

Claim:
A method of calibrating a position sensor in an automotive transmission having a transmission housing having mounted therein a casing for the position sensor which comprises a pressure member movably supported in the casing, and the position sensor actuated by the pressure member for measuring the position of the pressure member relative to the casing, wherein there is an initial determined position of the pressure member relative to the casing for each gear position after the casing of the position sensor has been mounted in the transmission housing, the method comprising the steps of: performing a calibration step comprising at least one measurement with the position sensor of a position of the pressure member relative to the casing for each gear position, defining a tolerance range for a value of each corresponding position measurement of the pressure member on the basis of the result of the position measurement, for each gear position to be detected, and storing the tolerance range for further position measurement and re-calibration.
