摘要: 再生制动是混合动力汽车区别于传统汽车的技术特点,是提高车辆燃油经济性的重要措施之一.以一种轴间力矩耦合的插电式并联混合动力汽车为研究对象,从再生制动分配算法的影响因素入手,提出了一种带有模糊控制的混合动力汽车再生制动能量管理策略.所设计的控制策略主要针对两个层面的控制决策,顶层是轴间制动力矩的分配决策,底层是再生制动电机所在的后轴力矩在摩擦制动与再生制动之间的分配决策.采用多种典型车辆行驶工况对所提出的模糊控制策略进行仿真研究.结果表明,所提出的模糊控制策略能够明显改善车辆的能量回收效果,与传统理想制动力分配曲线控制策略相比,能量回收最多可提高23.44%.

Abstract: Different from traditional internal combustion engine vehicles, hybrid electric vehicles (HEVs) have regenerative braking capability to improve fuel economy. Taking a plug-in parallel HEV with axles torque coupling as the research object, the influences of regenerative braking were analyzed. A regenerative braking control strategy using fuzzy control was then proposed. The presented strategy was to make two-layers control decision. The braking torque was allocated between the front axle and rear axle in the top layer, while the algorithm in bottom layer split the rear axle braking torque between mechanical braking and electric braking. The strategy was evaluated in a simulation study using several typical driving cycles. The results show that the as-proposed fuzzy control strategy can significantly improve the effect of energy recovery up to 23.44%, compared with that of the traditional ideal braking force distribution curve strategy.
