Abstract
A suspension system control according to the steps of: measuring a set of parameters indicative of motion of a body of the vehicle and of motion of wheels of the vehicle; determining a body demand force responsive to the measured parameters; determining a set of wheel demand forces responsive to the measured parameters; for each wheel of the vehicle: comparing the body demand force and the corresponding wheel demand force to determine whether the body demand force and the corresponding wheel demand forces are in phase; if the body demand force and the corresponding wheel demand force are in phase, determining a damper command responsive to the greater of the body and corresponding wheel demand force; if the body demand force and the corresponding wheel demand force are out of phase, determining the damper command responsive to the sum of the body demand force and the corresponding wheel demand force; and applying the determined damper command to a controllable variable force damper, wherein wheel vertical velocity occurring after a suspension event is minimized without sacrifice to passenger isolation from the suspension event.
