Abstract
An active vehicle height control method may include securing a road surface profile for unevenness of a road ahead of a vehicle and forming a target vehicle height profile by filtering the road surface profile. In addition, a controller is configured to form a disturbance profile using the road surface profile and the target vehicle height profile. The controller estimates vehicle behavior for the disturbance profile. Furthermore, the controller determines an inverse-phase control force that minimizes the estimated vehicle behavior, and drives an actuator using the inverse-phase control force to adjust a height of the vehicle.
