摘要

为克服干扰环境下无级自动变速汽车速比的无为控制,改善因速比波动导致的乘坐舒适性降低和电液控制系统能耗损失增加的问题,提出了离散化的金属带无级自动变速传动系统速比控制策略.在阐述无级自动变速传动系统现有最佳燃油经济性和最佳动力性控制曲线制定过程及其在干扰环境下所存在问题的基础上,分析了节气门开度和外界滚动阻力干扰对汽车传动系统速比和冲击度的影响规律,并通过建立新的离散化速比控制策略降低环境干扰的影响.结果表明,采用离散化速比控制策略,可有效地消减速比的波动,提高无级自动变速电液控制系统的工作效率.
 

Abstract

In order to eliminate the do-nothing control on the ratio of the metal belt continuously variable transmission(CVT) system, improve the driving stability and reduce the power consumption due to the ratio undulation, a new and discrete control strategy was established. The optimal control curves of economy and performance on the continuously variable transmission system were described, and the disadvantages of the conventional control strategy in jamming condition were analyzed. The influence of the throttle opening and roll resistance on the ratio and jerking of CVT system was simulated. A new discrete control strategy was used to reduce the jamming by the external condition. The results show that the wave ratio will be reduced and the work efficiency of the CVT hydraulic control system will be improved by the discrete control strategy.
