摘　　要：运用汽车制动稳定性理论对纯电动大客车BK6122的并行再生制动系统进行了分析,并根据ECE制动法规的要求,通过对比3种典型的再生制动控制策略,提出了一种计及变速器挡位影响的分段复合再生制动控制策略。对上述4种不同的控制策略进行了3种城市循环工况的仿真分析,结果表明所提出的控制策略在能量回收上明显优于其它的回收策略。The parallel regenerative braking system of a pure electric bus BK6122 is analyzed by applying vehicle braking stability theory, and after comparing three typical regenerative braking control strategies, a segmented compound regenerative braking control strategy considering the effects of gear position of transmission is proposed, in accordance with ECE braking regulations. Simulations on above-mentioned 4 control strategies with 3 city driving cycles are conducted with a result showing that the proposed control strategy is markedly superior to 3 other strategies in braking energy regeneration.
