应用馈能悬架的HEV能量管理研究和燃油经济性分析
|
摘要
为了提高混合动力汽车(HEV)燃油经济性,将馈能悬架技术应用到HEV中,基于等效消耗最小化(ECMS)的能量管理策略设计了HEV动力系统和悬架系统的监督控制器和子控制器,实现馈能悬架不同工作模式间的切换。建立HEV动力系统和悬架系统仿真平台,仿真中引入NEDC循环工况。结果表明馈能悬架的应用,能有效提高车辆的燃油经济性和车辆平顺性;同时,ECMS能够有效降低HEV的燃油消耗,并能更好的保持电池组SOC性能。
The fuel economy of hybrid electric vehicle can be effectively improved by using the energy regenerative suspension. Firstly, the effect of regenerative energy on HEV energy flow is analyzed, which provides a basis for the design of high-level supervisory controller and low-level sub-controllers of HEV power system and suspension system. Then the energy management strategy based on the equivalent consumption minimization is proposed based on the acceleration of the body and the dynamic load of the tire, and the switching between the different working modes of the feed suspension can be realized. Finally, the simulation model of HEV powertrain and suspension is established. The results prove that both fuel economy and ride comfort of HEV with energy regenerative suspension are improved. Meanwhile, the equivalent consumption minimization control strategy can effectively reduce the fuel consumption of HEV, and can better maintain the battery charge state.
