| 摘 要： | 在传统汽车制动理论的基础上,基于最大回收制动能量和制动的安全性,提出了一种全轮驱动混合动力汽车制动能量分配与再生制动控制策略.综合考虑电机电池效率等限制因素后,进行整车再生制动系统建模和典型制动工况下的仿真.结果表明,在制动车速为30 km/h,制动强度Z分别为0.1、0.3、0.5下最大能量回收率分别可达87.5%、47.8%、28.6%,采用提出的制动能量分配与再生制动控制策略能满足整车制动力分配的要求,并实现高效的制动能量回收.

| Abstract: | Based on the braking theory of conventional vehicles and high efficient energy recovery and security braking,a control strategy for braking energy distribution and regenerative braking of a 4WD hybrid electric vehicle was proposed.Considering limiting factors,such as motor and battery efficiency,a simulation model of a regenerative braking system was built and a simulation of typical braking conditions was conducted.The simulation result shows that the highest energy recycle ratio can reach 87.5%,47.8%,and 28.6% when z is 0.1,0.3,and 0.5,respectively,at 30 km/h.The control strategy for braking energy distribution and regenerative braking can satisfy demand for vehicle braking and obtain high regenerative energy. |
