Abstract
Direct yaw moment control (DYC) can generate the additional yaw-moment needed to maintain vehicle stability in the limit conditions so to improve the active safety of a vehicle's handling. A nonlinear vehicle dynamic model which meets the requirements of vehicle stability control experiments was established, and a sliding mode controller (SMC) was designed. The stability of the SMC controller was proved with Lyapunov function. At last the stability and control effect of the SMC was verified by simulations in Matlab/Simulink. The simulation results prove the effectiveness of the control algorithm and suggeste that the robustness of SMC is better than that of proportional-integral-derivative(PID) control algorithm, which proves SMC better application potential.
