US 2015/0176989 A1 · Accelerometer-Based Hill Angle Estimation

Abstract

The embodiments disclosed are directed to systems and methods for determining the inclination of a surface beneath a vehicle. In some embodiments, a method uses an accelerometer to determine a final surface inclination value. The final surface inclination value can then be used to compensate for the acceleration of the vehicle caused by gravity. The method includes receiving accelerometer values from the accelerometer. The method also includes determining surface inclination values based on the accelerometer values. The method further includes storing the surface inclination values. And the method includes applying a digital filter to the stored surface inclination values to determine a final surface inclination value.
