摘　　要：对双离合ISG混合动力汽车的结构和工作要求进行分析,针对双离合ISG混合动力汽车动力系统提出了动态、静态相结合的逻辑门限控制策略。根据设定的静态逻辑门限值判断整车所处的工作模式,在确定的工作模式下查找最佳工作点以控制发动机和ISG电机的输出转矩。基于Matlab/Simulink仿真软件建立动力系统仿真模型,并进行仿真分析。仿真结果表明,所采用的控制策略能够满足整车动力性要求,燃油经济性较传统汽车提高了19%,能有效降低混合动力汽车的尾气排放。The configuration and basic requirements of ISG hybrid electric vehicle with dual clutches were analyzed in detail. A logic threshold control strategy based on the power system of ISG hybrid electric vehicle with dual clutches was proposed, which integrated the static and dynamic control strategies. The operating model of the whole vehicle was decided according to static logic thresholds and then the optimal operating points were looked up in certain operating model to dynamically control engine output torque and ISG motor. Based on the software Matlab/Simulink the power system models were established and the performance of the ISG hybrid electric vehicle was simulated. It is concluded that the control strategy can match the dynamic demand of the whole vehicle. Compared with traditional vehicle the fuel economy can be improved by 19% and exhaust emissions of hybrid electric vehicle can be effectively reduced.
