| Abstract: | As a metal pushing belt continuously variable transmission system (CVT) is able to achieve more efficient operation with respect to drive performance and fuel consumption than conventional automatic transmissions, there has been considerable developmental activity in this area in recent years. In this paper, the dynamic simulation model of a metal pushing belt CVT is established when an automobile is in a starting or accelerating states. On the basis of the engine experiment, the automobile is controlled along an optimal economy curve in different throttle opening angles. A suitable control strategy is proposed to realize a smooth clutch starting and accelerating, and the changes of speed ratio of metal pushing belt CVT with time is obtained. The research results will be applicable to the layout and design of a CVT automobile. |
