Optimized roll behavior and ride comfort based on central roll torque distribution on electromechanical anti-roll bars and semiactive dampers and approaches on subjective-objective correlation

ABSTRACT: The following paper presents an approach to identify optimal roll behavior for passenger cars equipped with semiactive dampers and active electromechanical anti-roll bars. A central roll torque reference and a roll torque allocation interface are introduced which together allow for separated manipulation of transient and stationary roll behavior. A new subjective-objective correlation approach is presented which uses human perception models to improve matching between the objective and the subjective evaluation basis of roll dynamics to finally enable identification of optimal central roll torque reference.
