Abstract: Prodigious improvements have been attained in active vehicle safety systems region depending on different control systems. Active yaw control is one of these systems which target the vehicle stability in case of any rapid and/or severe manoeuvre. This paper presents the design of active yaw control system for (8 × 8) multi-wheeled vehicle and its integration with other safety control systems such as anti-lock braking system (ABS) and traction control system (TCS). A simplified vehicle model 'bicycle model' is employed to predict the desired vehicle yaw behaviour depending on road condition and driving situation. TruckSim-MATLAB/Simulink vehicle model was developed to verify the proposed integrated safety control system. The developed integrated active yaw controller with ABS and TCS succeeded in improving vehicle directional stability and traction performance. Furthermore, it should be mentioned that the road friction affects the controller efficiency as it limits the available braking torque to be used by the controller.
