Abstract
A method and apparatus for controlling continuously variable dampers in a vehicle suspension system is provided. A microcontroller receives sensor signals from the vehicle and generates heave, pitch and roll acceleration signals, heave, pitch and roll actual velocity signals, and heave, pitch and roll velocity level signals based on the received sensor signals. Heave, pitch and roll control signals are then calculated based on the acceleration, actual velocity, and velocity level signals, and the continuously variable dampers are adjusted in accordance with the calculated heave, pitch and roll control signals. A deadband schedule function is provided for adjusting the control signals in accordance with the significance of the particular ride event.
