摘要：

In order to improve the dynamic performance of vehicle equipped with continuously variable transmission (CVT), the dynamic model of CVT was established, and the maximum CVT ratio changing rate limited by reserve- power was calculated after taking the influence of reserve-power into consideration. The simulation of rapid acceleration and deceleration of vehicle was carried out using Matlab/Simulink software. The results indicate that the phenomenon of vehicle negative acceleration is eliminated effectively by the ratio changing rate control method, and the ride comfort and the response speed of vehicle are improved significantly during vehicle acceleration and deceleration.
