Damping Control to Enhance Transient Cornering Feel

Control to Synchronize Pitching with Rolling Utilized Kalman Filter

Abstract

This paper first analyzes the influence of the pitching motion caused by the rolling motion based on driver′s feeling in actual vehicle testing. It was concluded that the pitching motion enhances a cornering feel while driving, and the result was then utilized to develop a control law for the vehicle′s semi-active suspension, which synchronizes the rolling angle with the pitching angle. The law was further applied to a damping force control system of the vehicle. Finally, it was validated that the control law enhances a cornering feel after testing of the actual vehicle with the system.
