摘要
混合动力城市公交车运行过程中平均速度偏低,导致过度使用动力电池,由于无法使用混合动力,使得整个行驶工况中不能保持良好的燃油经济性。本文提出了基于车速和电池荷电状态(SOC)规划的控制策略,在MATLAB/Simulink软件中搭建所设计的控制策略模型,并将控制策略导入CRUISE软件中,与所搭建的整车动力系统模型进行联合仿真。研究结果表明:基于车速和SOC规划的混合动力客车控制策略与基于规则的控制策略相比,整车燃油经济性提高了2.7%,且SOC的平衡性可控制在5%以内。
The low average speed of hybrid city buses leads to the overuse of power batteries,which cannot maintain good fuel economy in the whole driving conditions.A control strategy was proposed based on the vehicle speed and battery state of charge(SOC)rules.The control strategy model was designed in MATLAB/Simulink software.Then the control strategy was imported into the CRUISE software to carry out co-simulation with the built vehicle power system model.The results show that the fuel economy of hybrid power control strategy based on SOC and speed planning is better than that based on rules.The fuel economy of whole vehicle is increased by 2.7%.The balance of SOC is less than 5%.
