基于多种循环工况的混合动力客车制动能量回收对燃油经济贡献率的研究

Research of Contribution Ratio of Regenerative Brake to Fuel Economy Based on Multi-cycles of Hybrid Electric Bus

建立再生制动能量回收的数学模型和试验评价方法,并针对某一并联混合动力城市客车,选择四种典型城市循环工况进行试验分析,得到不同行驶工况下混合动力客车的制动能量回收对整车燃油经济性的贡献率,对混合动力汽车的前期开发具有参考作用。

The authors establishe the mathematical model and experimental evaluation method of regenerative brake recovery and get the contribution ratio of regenerative brake to fuel economy to a parallel hybrid city bus based on four typical urban driving cycles.The results have reference progress in the early development of hybrid electric buses.
