再生制动系统是混合动力汽车和电动汽车特有的系统.该系统可将汽车制动过程中消耗的汽车动能和势能通过电动机发电的方式储存到电池中,在起动和加速过程中加以利用.本研究以长丰CJY6470E越野车为对象,在传统汽车制动理论的基础上,基于制动安全及制动效能,提出一种混联式混合动力汽车制动能量分配与再生制动控制策略.前后轴采用理想制动力分配,在分配好后,再对前后轴的再生和摩擦制动进行二次分配.进行二次分配时,主要考虑电机及电池的使用寿命,以车速及SOC作为电机再生制动功率影响因素,并通过对ADVISOR2002进行二次开发,建立整车模型,最后进行仿真.结果表明,采用所提出的再生制动控制策略可实现高效的制动能量回收,延长电池的使用寿命,且该策略具有可行性.

The regenerative braking system is a unique system in electric vehicles and hybrid electric vehicles.The system can restore the kinetic energy and potential energy,during start and accelerating,into battery through electrical machines.The focus of this paper is on Changfeng CFA6470E HEV.Based on the braking theory of conventional vehicles and security braking and high efficient energy recovery,a control strategy for braking energy distribution and regenerative braking of an SP-HEV is proposed.The ideal braking force distribution is used in the front axle and real axle braking force distributions.After the front axle and real axle's braking force is distributed,regenerative braking and friction braking are assigned.The characteristics of motor and battery's life have been taken into account in the quadratic distribution method,The motor's speed and SOC are taken as the braking power's influencing factors.ADVISOR2002 is redeveloped for the simulation model.The simulation result shows that the control strategy for braking energy distribution and regenerative braking can satisfy demand for vehicle braking and extend the life of battery.The strategy proves to be practical.
