摘要：
非插电式混合动力汽车有多种工作模式，控制边界复杂，节油效率不同，多组经济性试验差异明显，为客观准确测试其经济性，对其试验方法进行深度研究。首先，基于虚拟仪器构建混合动力汽车测试系统，以满足多路CAN信号、底盘测功机车速、燃料消耗量、动力电池电流等信号高频率实时同步采集，并进行相应硬件选型工作；其次，基于非插电式混合动力的动力电池快速放电/充电方式高效率高精度控制动力电池边界进行多组实车试验，验证测试系统的可靠性；最后，深度解析非插电式混合动力汽车的燃料修正系数与动力电池试验边界匹配性，为其燃料消耗量一致性研究提供优化方向。试验样车在动力电池SOC 62%左右时，NEDC工况综合油耗达仅7.5 L/(100 km)，动力电池SOC 36%时综合油耗达到9.7 L/(100 km)，通过不同燃料修正系数折算后，其综合油耗均在8.5 L/(100 km)左右。

Abstract: Non-plug-in hybrid electric vehicles have multiple working modes, complicated control boundaries, different fuel-saving efficiency, and obvious differences in multiple sets of economic tests. In order to test their economics objectively and accurately, they have conducted in-depth research on their test methods. Firstly, a hybrid vehicle test system based on virtual instruments was built to meet the high-frequency real-time synchronous acquisition of multiple CAN signals, chassis dynamometer vehicle speed, fuel consumption, power battery current, and corresponding hardware selection work. Secondly, based on the non-plug-in hybrid power battery fast discharge / charge method with high efficiency and high precision to control the boundary of the power battery, multiple sets of real car tests were conducted to verify the reliability of the test system. Finally, the in-depth analysis of the compatibility between the fuel correction coefficient of non-plug-in hybrid vehicles and the power battery test boundary provides an optimization direction for the research on the consistency of its fuel consumption. When the sample vehicle is around 62% SOC of the power battery, the comprehensive fuel consumption of the NEDC is only 7.5 L/(100 km), and that of the power battery is 9.7 L/(100 km) under the operating condition of 36% SOC. After conversion through different fuel correction factors, the comprehensive fuel consumption is about 8.5 L/(100 km).
