摘　　要：提出一种燃料电池功率主导轻型混合动力汽车的整车控制策略.构建了燃料电池混合动力系统构型,建立了高压燃料电池发电系统控制约束模型,制定了7种工作模式和以燃料电池输出功率为主导、电池组SOC维持型的控制逻辑.整车试验结果表明,燃料电池输出功率能很好地跟踪驾驶员踏板的功率需求,整车燃氢经济性为2.464kg/100km.A new control strategy for a fuel cell-oriented hybrid electric vehicle is proposed. The fuel cell hybrid electric vehicle power train is built up and control-limitation model for the high-pressure fuel cell engine is set up. Seven working modes are established and the control logic to realize the fuel cell as the primary power source and maintain the SOC of battery pack is constructed. Experimental results indicated that the fuel cell power can follow the driver＇s requirements very well. The hybrid vehicle＇s hydrogen consumption is up to 2.464 kg/100 km.
