摘　　要：为探究环境温度对混合动力汽车油耗的影响程度,选取不同技术路线的4辆混合动力汽车进行了不同温度下的多次实际道路行驶油耗测试,结果表明,插电式混合动力汽车(PHEV)和增程式混合动力汽车在实际道路行驶时的油耗结果明显高于试验室油耗测试结果,不可外部充电式混合动力汽车(NOVC-HEV)及PHEV在高温、低温环境下油耗均会出现明显上升,故常温条件下全球统一轻型车辆测试循环(WLTC)工况油耗测试结果不能准确反映NOVC-HEV、增程式混合动力汽车和PHEV车型的真实油耗水平,环境温度是影响混合动力汽车油耗表现的重要因素。In order to explore the influence of ambient temperature on the fuel consumption of Hybrid Electric Vehicle(HEV),this research team selected four HEVs with different technical routes to conduct several real driving fuel consumption tests at different temperatures.The results show that fuel consumption of Plug-in Hybrid Electric Vehicle(PHEV)and Range Extended Electric Vehicle(REEV)is apparently higher than lab fuel consumption test value,and that of None Off-Vehicle-Charging Hybrid Electric Vehicle(NOVC-HEV)and PHEV increases significantly under high and low temperature environments.Therefore,it is concluded that the WLTC test at room temperature cannot accurately reflect the real fuel consumption level of NOVC-HEV,REEV and HEV models,and the ambient temperature is an important factor affecting the fuel consumption of hybrid electric vehicles.
