ABSTRACT:
A system and method for estimating vehicle roll rate and roll angle. The system includes a suspension deflection sensor provided at each wheel of the vehicle that provides suspension measurement signals indicative of the roll of the vehicle. The system also includes a roll rate estimator that uses the suspension measurement signals and an estimated tire deflection of the wheels to provide a roll rate estimation signal. The system also includes a vehicle roll angle and a roll rate estimator that uses the roll rate estimation signal and a dynamic model to estimate the roll angle and refine the roll rate. The roll rate estimator calculates the roll rate one way if none of the vehicle wheels are off of the ground and calculates it another way if any of the wheels are off of the ground.
