Method of calibrating a rollover sensor

摘要

A rollover sensor for a vehicle continuously determines the inclination of a vehicle in at least one axis. In order to cancel drift deviations in the sensor, the inclination is average in the at least one axis, continuously along a defined route. The formed average value is assumed as the zero position. Inclination of the vehicle due to inclination of the road surface is compensated based on variations in ambient air pressure indicative of changes in altitude.
