When the speed ratio of the vehicle equipped with CVT changes rapidly, the acceleration of the vehicle will change synchronously, that means to exert an extra force on the driving tires. Using this feature, the desired results can be obtained in certain specific conditions, such as vehicle cornering at high speed. The models of multi DOF vehicle and CVT transmission were established to study the rapid changes in the turning process of the vehicle through the CVT ratio control. This paper introduces a method based on safety factor of CVT speed ratio control strategy. The simulation results show that if the driver fails to effectively reduce vehicle speed during high-speed cornering. As the speed ratio of CVT increasing rapidly, and the backward force can be acquired on the driving wheel, so that the vehicle can keep straight in a short time while reducing vehicle speed. The results of this paper can achieve better control results if the engine fuel injection control is combined.
