摘　　要：介绍针对一款12米级并联式混合动力公交车燃油经济性的优化控制策略,该控制策略通过减速能量回馈、发动机自动启停、智能充电等手段有效提升动力源综合效率、减少能量损耗。最后利用不同路况仿真配合实车车辆油耗对比验证该款混合动力公交车在确保动力性的前提下能够实现行车中燃油经济性相对传统公交降低近40%(百公里节油约16 L)的优化效果。This paper shows a kind of control strategy for parallel hybrid bus, which effectively improves powertrain efficiency and reduces fuel consumption by deceleration energy feedback, engine auto start/stop, smart charge. And the results of simulation for different driving cycles and real bus driving comparison show this hybrid bus can reduce nearly 40% fuel consumption compared with tradi- tional buses.
