This paper utilizes a linear two-degree-of-freedom vehicle model to calculate the nominal value of the vehicle�s nondrive-wheel\nspeed difference and investigates methods of estimating the yaw acceleration and sideslip angular speed. A vehicular dynamic\nstability control system utilizing this nondrive-wheel speed difference is then developed, which can effectively improve a vehicle�s\ndynamic stability at a very low cost. Vehicle cornering processes on roads of different frictions and with different vehicle speeds are\nexplored via simulation, with speed control being applied when vehicle speed is high enough to make the vehicle unstable. Driving\nsimulator tests of vehicle cornering capacity on roads of different friction coefficients are also conducted.
