中文摘要: 为了解决司机驾驶特性和实际道路工况差异导致的混合动力公交车(Hybrid Electric Vehicle,HEV)能耗表现恶化的问题,本研究提出了面向人-车-路协同控制的混合动力公交车能量管理思想。该思想通过研究司机驾驶特性对HEV公交车能耗的作用机理,建立典型司机驾驶特性样本库,在司机特性实时辨识和道路工况预测的基础上,优化设计全历程电池能量曲线,匹配整车扭矩分配比,最终引导发动机运行工况点向燃油经济性高的区域趋近,以降低整车运行能耗。这种综合能量管理思想可以降低司机驾驶操作以及道路工况因素对HEV公交车能耗的影响,并改善HEV公交车的燃油经济性,具有很强的实用价值。研究成果将完善和补充HEV公交车控制策略理论,具有重要的科学意义,对于其他动力类型车辆同样有重要参考价值。

英文摘要: A new energy optimization methodology for the hybrid electric vehicle (HEV) bus was proposed to solve the adaption problem resulted in the difference of driver behavior and the variability of real world driving cycle based on the driver-vehicle-road interaction.The relationship between the difference of driver behavior and energy consumption was investigated specifically and it was focused to improve the practical endurance mileage based on the optimization of driver torque demand and the design of battery discharge curve as well as matching the power allocation which changed the engine operating path to the high efficiency area which the key problem is the prediction of driving cycle and the database of typical driver behavior characteristics.This new energy management methodology was strongly practicable and had great potentiality to improve the efficiency of the HEV bus through decreasing the influence to the energy consumption duo to the inappropriate driver behaviors as well as overcoming the mismatching problem between the control variables and the real world driving cycles.The results of this study will provide important scientific significance of enriching and developing HEV bus control theory which also have important reference value to other power-train vehicle.
