Abstract
A system and method for facilitating ride and stability control of a vehicle. The system includes a plurality of suspension displacement sensors, with each of the plurality of suspension displacement sensors positioned proximate to a suspension element of the vehicle. The system further includes a nonlinear filter for filtering out a wheel hop frequency from the suspension velocity corresponding to at least one of the plurality of suspension displacement sensors to obtain a resultant suspension velocity. The resultant suspension velocity is used by a control unit to determine the pitch velocity, roll velocity and the heave velocity of the vehicle.
