摘要
通过对发动机燃油消耗特性的研究,提出一种较为简单的动态三参数最佳燃油经济性换挡规律制定方法。同时,分析了汽车质量变化对换挡规律的影响,设计了一种考虑质量变化因素的变结构换挡系统模型,并利用 Matlab/Simulink 对该模型进行了仿真,仿真结果表明,该模型可以使汽车获得更佳的燃油经济性,对最佳燃油经济性换挡规律的理论研究及实际应用具有重要意义。
Through researches on fuel characteristics of the engine, a new method for establishing dynamic 3-parameter-controlled optimal fuel-economy shifting schedule was presented. At the same time, by analysis of influences of mass on shifting schedule, a variable-structure-controlled shift system was designed. Based on the software of Matlab/Simulink, the variable-structure-controlled shift system was simulated. Simulation results show this system can improve the fuel economy of vehicle obviously.
