摘要： 针对开发的双行星排式混合动力系统,选取超级电容作为唯一的电源储能器,对超级电容进行选型和参数匹配。基于模糊控制理论和整车燃油经济性目标,提出了发动机最优曲线的控制策略并给出了具体实施的方法。为验证控制策略的实际控制效果,样车进行了台架试验,测试结果表明:在典型综合城市工况下,发动机工作点按照目标曲线运行,克服了传统PI控制中发动机转速波动大、油耗高的缺点,使用模糊控制算法的整车综合油耗为21.44 L/100 km,相比传统PI控制算法节油率提高了4.88%。

Abstract: For a developed dual-planetary hybrid system, the supper capacitor was selected as the only power resource and the parameters of ultra capacitor were matched. Based on fuzzy control theory and the target fuel economy, the optimal curve of the engine control strategy was proposed and the concrete implementation method was given. To verify the actual effect of the control strategy, a trial bus was tested on the bench. The results show that in a typical city driving cycle, the engine working points are highly accorded to the target curve and overcome the problems in traditional control, such as engine speed fluctuation and high fuel rate. The fuel consumption of fuzzy control algorithm of the vehicle is 21.44 L/100 km. Compared with the traditional PI control algorithm, the economizing rate increases 4.88%.
