摘要
为了找出车速超过120 km/h时汽车燃油消耗规律,用实车实验和网络平台实验数据对汽车燃油消耗进行了预测研究.利用SPSS对ELM237采集的汽车瞬时等速油耗实验数据和网络平台提供的实验数据进行曲线拟合,结果表明瞬时油耗与车速具有极高的相关性,相关系数均超过0.95,并且符合二次曲线和三次曲线分布规律.用二次曲线和三次曲线对两种方法获取的实验数据进行了分析预测,结果显示当车速达到140 km/h、160 km/h和180 km/h时,油耗将分别达到车速为120 km/h时的1.30倍、1.74倍和2.09倍.
In order to find out the rules of vehicle fuel consumption when the speed is over 120 km/h,the vehicle fuel consumption is predicted based on real vehicle experimental data and network platform experimental data.SPSS is used to perform curve fitting on the experimental data of instantaneous constant speed fuel consumption collected by ELM237 and the experimental data provided by the network platform.The results show that instantaneous fuel consumption is highly correlated with speed.The correlation coefficients are all over 0.95,and accord with the conic and cubic curve distribution law.The experimental data obtained by the two methods are analyzed and predicted with conic and cubic curves,the results show that when the vehicle speed reaches 140 km/h,160 km/h and 180 km/h,the fuel consumption will reach 1.30 times,1.74 times and 2.09 times respectively as the vehicle speed is 120 km/h.
