摘　　要：针对后轮驱动纯电动汽车,分析了机械制动力前后分配比和踏板特性是否可调以及是否装备ABS等3种不同基础条件对制动能量回收策略的影响,设计与对比了两种并联制动策略(P1与P2)和3种串联制动策略(S1A/B与S2)。6种典型循环工况下的仿真结果表明,S1A/B制动能量回收策略的回收率相对于并联制动策略有显著提升,且对应的基础条件较容易实现。因此,S1A/B策略为后驱纯电动车较为值得推荐的制动能量回收策略。In this paper, the effects of three different base conditions （i. e. the adjustability of the distribu- tion ratio of mechanical braking force between front and rear wheels, the adjustability of brake pedal characteristics, and the availability of ABS） on the regenerative braking strategy for rear-wheel drive electric vehicle are analyzed. Two parallel braking strategies （P1 and P2） and three series braking strategies （S1A, S1B and S2） are devised and compared. The results of simulations with six typical driving cycles indicate that regenerative braking strategies S1A and S1B have obviously higher energy recovery rate with their corresponding base conditions easier to implement, compared with parallel braking strategies, thus are more worthy to recommend for rear-wheel drive electric vehicles.
