摘要

为研究功率分流式混合动力系统整车高速工况经济性优化问题,提出在高速工况下采用制动器B2锁止、功率损耗最小的控制策略方案。综合考虑发动机、电机、电池的功率损耗,建立混合动力系统模型,并对该方案进行仿真验证及整车试验。结果显示,优化后的整车高速工况经济性有明显提升。制动器B2锁止、功率损耗最小的控制策略有助于提升整车高速工况经济性。
        In order to research the fuel consumption optimization of the vehicle′ s power split hybrid powertrain at highspeed operation,a control strategy to lock the brake B2 and make the vehicle′ s system with minimum power loss at high-speed operation is proposed. The power loss of the engine,motor and battery was comprehensively considered,the hybrid power system model was established,and the simulation verification and vehicle test were performed for the scheme. The result shows that the fuel consumption of the optimized vehicle at high-speed operation has obviously improved. The control strategy to lock the brake B2 and make the system with minimum power loss is contribute to reduce the fuel consumption of the vehicle at highspeed operation.
