Integrated Control of 4-Wheel Independent Brakes and Suspension Damping for Enhanced Lateral Stability

This paper presents an integrated chassis control system equipped with electronic stability control (ESC) and continuous damping control system (CDC) in order to improve the stability, responsiveness, and agility features. Recently, vehicles are equipped with chassis control devices improving the vehicle stability and handling in fast evasive maneuvers. The coordination of these chassis control devices can give synergies such as between the agility control with ESC and CDC. At first, this paper describes the influence of specifying a CDC control strategies to effect the handling dynamics. The following description is calculation of lateral tire force deviation by damping forces. An integrated chassis controller has Supervisor, Controller and Coordinator. Simulations on vehicle simulation software, CarSim, show the proposed simulation based optimization is effective for the integrated chassis control.
