This article presents the capability of several active systems and smart actuators to control the vehicle yaw motion for various driving situations. A control concept allowing for a centralised coordination of multiple actuators is described. The additional yaw torque generated through system control interventions is determined taking account of the vehicle side slip angle and the lateral acceleration. Analysis results are illustrated for the active front steering and brake system, active differential and active anti-roll bars. The developed control concept is based on a centralised yaw torque allocation algorithm. The concept comprises the coordination of the considered active systems and the identification of required interventions to control the vehicle yaw motion. A sine with dwell time open-loop manoeuvre is utilised to illustrate the stability and agility improvement achieved by the centralised and coordinated control strategy.
