The invention discloses a method and system for determining the overall pitching degree of a large motor vehicle, and the method comprises the steps: S1, obtaining the distance between the head part and the ground and the distance between the tail part of the vehicle and the ground through at least one pair of range finders, and obtaining an original data set; s2, carrying out filtering processing on the original data set; s3, selecting a short-time data set from the filtered data set according to the data acquisition time of the range finder, and averaging the data in the short-time data set; s4, calculating to obtain a pitching degree value of the vehicle by utilizing a pitching degree calculation formula and based on the averaged data; and S5, based on the pitching degree value of the vehicle, the vehicle adjusts the emission angle of lamplight according to the pitching degree value. The at least one pair of range finders are arranged at the head part and the tail part of the vehicle to obtain the data of the distances between the head part and the tail part of the vehicle and the ground, and the pitching degree of the vehicle is calculated, so that compared with an existing method and system, the calculation method is simple, the response speed is high, and the calculation result is accurate.
本发明公开了一种用于确定大型机动车辆整体俯仰度的方法和系统,包括:S1:利用至少一对测距仪分别获取车辆首部和尾部与地面的距离,得到原始数据集;S2:对所述原始数据集进行滤波处理;S3:根据测距仪采集数据的时间,从滤波处理后的数据集中选取出短时数据集,并对所述短时数据集中的数据取平均值;S4:利用俯仰度计算公式,并基于取平均值后的数据,计算得到车辆的俯仰度值;S5:基于车辆的俯仰度值,使车辆根据所述俯仰度值调节灯光的发射角度。本发明通过设置至少一对测距仪在车辆的首部和尾部,获取车辆的首部和尾部与地面距离的数据,并计算出车辆俯仰度,相比于现有方法和系统,本发明的计算方法简单,反应速度快,且计算结果精确。
