Abstract
An active vehicle suspension system includes an active damping mechanism operatively coupled to a vehicle wheel and configured for controlling a damping force applied to the wheel responsive to a control signal. A controller is operatively coupled to the damping mechanism and configured for generating a control signal to the damping mechanism responsive to velocity of the wheel in a downward vertical direction. At least one of a timer threshold and velocity threshold, used to determine whether a vehicle wheel has encountered a depression in a road surface, may be varied on a basis of a speed of the vehicle. A damping mechanism for a rear wheel of a vehicle may be controlled on a basis of how a damping mechanism for a front wheel is controlled.
