Abstract
An inclination detection system is disclosed. The inclination detection system may have an inclination angle predictor configured to calculate an a priori estimated inclination angle of the machine based on a previously estimated inclination angle, and a measurement variance calculator configured to calculate a measurement variance of the a priori estimated inclination angle based on a non-gravitational acceleration of the machine. The inclination detection system may also have an inclination angle sensor configured to measure a measured inclination angle of the machine, and an inclination angle updater configured to determine an a posteriori estimated inclination angle of the machine based on the a priori estimated inclination angle, the measurement variance of the a priori estimated inclination angle, and the measured inclination angle.
