【摘要】：根据双轴并联式混合动力客车的结构形式以及所运行的中国典型城市工况,选用并联电辅助控制策略.基于该控制策略,以并联式混合电动客车的工作模式和油门开度作为2参数设计变量,提出了一种分段交叉式的换挡规律设计方法,即在不同的工作模式和油门开度下,选择合适的换挡规律的交叉式设计方法.利用AVL Cruise仿真软件建立了整车模型,与Matlab联合仿真,设计了并联电助力式控制策略及换挡规律,并对该双轴并联式混合动力客车的动力性、经济性进行了仿真分析.结果表明:该换挡规律与最佳经济性换挡规律相比在加速性能方面提高了6.3%,与最佳动力性换挡规律相比经济性有了很大改善;能够在保证整车动力性的同时兼顾经济性,是一种更加合理的整车换挡规律.
[Abstract]:According to the structure of the two-axis parallel hybrid electric bus and the typical urban operation in China, a parallel electrically assisted control strategy is selected. Based on the control strategy, taking the working mode and throttle opening of the parallel hybrid electric bus as two parameter design variables, a new design method of shift law is proposed, that is, under different working modes and throttle opening. Select the appropriate shift law of the crossover design method. The whole vehicle model is established by using the AVL Cruise simulation software, and the parallel electrically assisted control strategy and shift law are designed, and the power and economy of the two-axle parallel hybrid electric bus are simulated and analyzed. The results show that compared with the best economic shift law, the shift law improves the acceleration performance by 6.3%, and the economy is greatly improved compared with the optimal power shift law, which can guarantee the power performance of the whole vehicle and give consideration to the economy. Is a more reasonable vehicle shift law.
