This paper proposes a comparison study of two vehicle stability control methods by direct yaw-moment control (DYC): a PID and a sliding controller. For the purpose of this study, control systems are based solely on vehicle side-slip angle state feedback and the lateral dynamics of the 2 DOF vehicle model are used to establish the desired response. Close-loop dynamics of the PID controller are determined with the pole placement method, and an anti-windup strategy is adopted to respond to the tire’s nonlinear characteristics. The comparison study was performed by computer simulations with a 14 DOF nonlinear vehicle model validated with experimental data. The controllers are evaluated for typical severe manoeuvres on low friction road surfaces. It is found that despite their fundamental differences, the control methods provide comparable performances for the cases studied.
