The invention provides an automobile data acquisition system performance analysis method for an automobile following scene. The method comprises the following steps: S1, acquiring real-time driving data of a to-be-tested vehicle through a data acquisition system; S2, installing distance measuring systems on the detection vehicle and the to-be-tested vehicle; S3, calculating an acquired data consistency evaluation value of the data acquisition system according to the acquired real-time driving data and the driving data reference true value; S4, dividing the relative longitudinal distance detected by the distance measuring system into three intervals; S5, calculating a root-mean-square error and a mean absolute error of the real-time driving data of the to-be-tested vehicle in each interval; S6, calculating an equivalent weight through a root mean square error; and S7, calculating the acquisition precision value of the data acquisition system through the equivalent weight and the mean absolute error. The performance analysis method of the automobile data acquisition system for the automobile following scene solves the problem that the test result of the existing automobile following scene acquisition performance method of the data acquisition system is not accurate enough.

    本发明提供了一种用于跟车场景的汽车数据采集系统性能分析方法,包括以下步骤:S1:通过数据采集系统采集待测车的实时行驶数据;S2:在检测车和待检测车上安装测距系统;S3:通过采集到的实时行驶数据和行驶数据参考真实值计算数据采集系统的采集数据一致性评估值;S4:将测距系统检测到的相对纵向距离划分为三个区间;S5:计算每个区间内的待测车实时行驶数据均方根误差、平均绝对误差;S6:通过均方根误差计算等效权重;S7:通过等效权重与平均绝对误差计算得到数据采集系统采集精度值。本发明所述的一种用于跟车场景的汽车数据采集系统性能分析方法解决了现有验数据采集系统的跟车场景采集性能方法测试结果不够精确的问题。
