Abstract:
A method for automatically determining a current offset value for the zero-point correction of a vehicle inclination sensor including the steps of while driving in a first driving direction, the current driving resistance is determined repeatedly, without regard to the sensor and stored temporarily, and a current raw signal value of the sensor is noted. Upon a change in the driving direction, the last-noted raw signal value is stored temporarily and while driving in the second driving direction. The current driving resistance is determined repeatedly, without regard to the sensor and stored temporarily. Then, if the difference between the two stored driving resistances agree with a tolerance threshold, the noted raw signal value is stored as the offset value for the zero-point correction of the inclination sensor.
