Method for automatic calibration of automatic transmission
First Claim
1. Method for automatic calibration of position detection sensors of an automatic transmission comprising a plurality of gearshift actuators, each associated with an individual position detection sensor, the method comprising:
- registering, using the position detection sensors, the position of at least two gearshift actuators upon power-up of the transmission; and
performing a calibration of the associated position detection sensors if each registered position of the at least two gearshift actuators is outside of a predetermined expected position range of the gearshift actuators, or if each registered position of the at least two gearshift actuators is within a predetermined abnormal position range of the at least two gearshift actuators.
