插电式混合动力汽车再生制动控制策略

由于再生制动控制策略直接影响了插电式混合动力汽车（PHEV）的经济性,文章提出了一种基于理想制动力分配的再生制动控制策略,这种策略能在保证制动稳定性的同时,尽可能多地回收制动能量,在Simulink平台上建立再生制动控制策略模型,并嵌入到Cruise软件中进行仿真。仿真结果表明,此模型相比没有制动能量回收的PHEV和传统汽车,都有效地提高了经济性,验证了再生制动控制策略的合理性。

Control Strategy on Plug-in Hybrid Electric Vehicle Regenerative Braking

Regenerative braking control strategy directly influenced fuel economy of Plug-in hybrid electric vehicles. A style of a control strategy based on ideal braking force is proposed in this paper. This strategy can ensure braking stability, at the meantime reclaim the braking energy as much as possible. And the control strategy model of regenerative brake system is built based on Simulink. The control strategy model is imbedded in Cruise and simulated. The simulation results show that compared with PHEV with no braking energy recovery and traditional vehicles fuel economy is improved and the control strategy of regenerative braking system are proved to be appropriate.
