摘　　要：在混合动力汽车前期开发的能量管理策略的基础上,提出了一套基于混合动力汽车能量管理策略的诊断算法集成方案。该方案在能量管理策略的基本架构中分别集成故障检测、故障确认、故障识别、部件故障等级划分和容错控制。为验证该方案的有效性,基于Cruise软件平台下搭建整车模型,同时在Matlab/Simulink中搭建系统算法进行仿真实验。硬件在环仿真结果表明,本文集成方案实现了能量管理策略与故障诊断算法的无缝连接,在有效检测故障的同时实施相应的容错控制。An integration scheme is proposed to effectively integrate fault diagnosis algorithm into energy management strategy for hybrid electric vehicle.In this scheme,the fault detection,fault recognition,fault identification,fault rank division and fault tolerance control are integrated into the general energy management architecture.In order to verify the effectiveness of the proposed scheme,a fault diagnosis algorithm-integrated energy management strategy is established using MATLAB/Simulink combined with models constructed by Cruise software.Hardware-in-the-loop simulation results show the fault diagnosis algorithm-integrated energy management strategy can detect the vehicle faults and apply fault tolerance control accordingly.Meanwhile,the fault diagnosis algorithm and energy management strategy are effectively coordinated.
