摘要
基于无级变速传动系统动力学仿真模型与自适应模糊控制策略，综合考虑后备功率、动力传动系损失和CVT速比变化响应滞后的影响，提出了τ算法、发动机转矩补偿和发动机转速补偿3种控制方法，并分别对采用这3种控制方法时的动力性与燃油经济性进行仿真分析。结果表明，相对于常规控制，采用这3种综合控制方法后动力性基本保持不变，而经济性则分别提高了约2．9％～3．5％。
Based on dynamics simulation model for continuously variable transmission system and adaptive fuzzy control strategy, with the consideration of the effects of reserve power, powertrain loss and the response lag to CVT ratio change, three control schemes i. e. τ algorithm, engine torque compensation and engine speed compensation are proposed, and a simulation analysis on the power performance and fuel economy under three control schemes are conducted respectively. The results show that compared to the conventional control, the three control schemes proposed can raise fuel economy by around 2.9% to 3.5% respectively while keeping the power performance intact.
