摘要：针对传统的燃油矿用卡车油耗大、碳排放高、环境污染严重等问题，以柴油矿卡为原型，采用串联式结构建立增程式矿卡混合动力系统模型，设计复合功率跟随策略和基于电池荷电状态（state of charge，SOC）反馈的自适应等效燃油最小消耗策略（advanced equivalent consumption minimization strategies，A-ECMS），利用AVL Cruise软件搭建整车模型，通过MATLAB/Simulink嵌入控制策略进行联合仿真，评估两种能量管理策略的控制效果。结果表明：两种策略下矿卡的仿真车速与需求车速高度相符，动力系统能够满足不同运行工况下的动力需求和能量分配；A-ECMS策略下动力电池最终SOC比复合功率跟随策略更接近初始值，偏差仅为0.3%且波动较小，百公里等效燃油消耗比复合功率跟随策略低2.36 L。综合考虑动力电池的SOC波动以及矿卡的等效燃油消耗，A-ECMS策略更具优势。

Abstract: In response to the problems of high fuel consumption, high carbon emissions and pollution in traditional fuel mining trucks, a hybrid power system model for extended range mining trucks is established using a series structure architecture based on diesel mining trucks. A composite power following strategy and advanced equivalent consumption minimization strategies (A-ECMS) based on battery state of charge (SOC) feedback are designed. A vehicle model is built based on AVL Cruise, and the control effects of the two energy management strategies are evaluated through joint simulation using MATLAB/Simulink embedded control strategies. The results show that the simulated vehicle speed of the mining truck under both strategies is highly consistent with the required vehicle speed, and the power system can meet the power demand and energy allocation under different operating conditions. Under the A-ECMS strategy, the final SOC of the battery is closer to the target value than the composite power following strategy, with a deviation of only 0.3% and small fluctuations. The equivalent fuel consumption per 100 kilometers is 2.36 L lower than the composite power following strategy. Taking into account the SOC fluctuations of the power battery and the equivalent fuel consumption of the mining truck, the A-ECMS strategy has more advantages.
