Abstract
An attitude angle estimator and method of estimating attitude angle of a vehicle having an angular attitude rate sensor sensing angular attitude rate of a vehicle, a vertical accelerometer sensing vertical acceleration, and a lateral accelerometer sensing lateral acceleration. An attitude angle estimate is produced and is updated as a function of the sensed angular attitude rate. An acceleration-based attitude angle is determined as a function of the sensed accelerations, and a blending coefficient is provided. A current vehicle attitude angle estimate is generated as a function of the updated attitude angle estimate, the acceleration-based attitude angle, and the blending coefficient.
