This paper presents a control logic for the active suspension system that consists of a damper and motor/pump combination. The proposed logic, intended to improve vehicle handling performance, generates the active force to control body motion and the damping force to maintain basic ride performance. The active suspension system’s damping force is controlled by adjusting the back electromotive force. The motor generates the active force by generating a pressure difference inside the damper. In this paper, the logic is designed based on the 1DOF vehicle roll/pitch model and vehicle state estimator. The system and logic were realized on the large sedan vehicle, and handling performance of the logic was verified through various vehicle tests. |
