1、混合动力汽车再生制动对能耗影响的试验研究摘要：基于某地面耦合型油电混合动力汽车，研究再生制动对整车能耗影响，为进一步开发混合动力汽车的制动能量管理策略奠定基础。通过新欧洲驾驶循环(NewEuropeanDrivingCycle,NEDC)循环工况再牛制动过程分析，研究发动机启停控制、电池荷电状态(StateofCharge,SOC)对再生制动回收能量的影响，采用单次NEDC循环工况再生制动能量回收效率来评估再生制动控制策略对整车能量消耗的影响。测试结果表明，再生制动过程发动机的启停控制主要受电池SOC的影响，电池SOC越低，发动机启动时刻越提前，停机时刻越延迟，再生制动回收的能量越多,单次循环
2、工况制动能量回收率越高。关键词：混合动力；再生制动；制动能量回收率；控制策略中图分类号：U467.1文献标识码：ATestingResearchontheEffectofRegenerativeBrakingonEnergyConsumptionofHybridElectricVehicleTheEffectofRegenerativeBrakingonEnergyConsumptionofHybridElectricVehiclesResearchTANGGuoqiangl,XULeil,ZHOUZhoul,WANGHongrongl,ZHANGYuanjian2TANGGuoqiangl,
