为了提高功率分流式混合动力系统汽车的燃油经济性,建立了混合动力系统物理模型和系统控制模型,利用优化初值的粒子群算法对混合动力系统的效率进行优化,仿真得到效率最优时的功率分流控制策略,并将其移植到搭载了该系统的某公交车上,进行了实验验证。结果表明,优化初值的粒子群算法可以有效提高动力系统的综合系统效率,降低整车油耗。
In order to improve the fuel economy of the power diffluence hybrid vehicle,a physical model of the hybrid system and a system control model are established. The PSO (Particle swarm optimization) with optimized initial value is used to optimize the hybrid power system efficiency. The optimal power diffluence control strategy is obtained by simulation and it is transplanted to a bus equipped with the hybrid power system and experimentally verified. The results show that the efficiency optimization algorithm can effectively improve the comprehensive system efficiency of the power system and reduce the fuel consumption of the vehicle.
