摘要
无级变速汽车传动系控制策略是开发无级变速传动系的理论基础。为提高无级变速汽车的综合性能,建立了无级变速传动系整车模型,研究了无级变速传动系统的特性,提出3种典型的换档策略,并对综合模式控制策略进行了仿真研究。结果表明,综合控制模式可实现车速与发动机的分别控制,在保证汽车动力性的同时,达到燃料经济性的最佳值。
The control strategy is the theory foundation of the continuously variable transmission system. To improve the vehicle performance with CVT （ Continuously Variable Transmission）, the model of vehicle with CVT is made. The characteristics of the CVT is studied, three typical shifting strategy of the CVT is presented and compositive control strategy is researched on by simulation. The result shows that the compositive control strategy ensures the driving performance of vehicle with optimal fuel economy.
