The invention relates to a road gradient measuring method which comprises the following steps: at a first moment, obtaining a first vertical vector G of a vehicle-mounted sensor in a vertical direction in a sensor coordinate system; at a second moment, obtaining a second vertical vector Gse of the sensor in the vertical direction of the sensor coordinate system; the gradient direction is obtained based on the vector value change of the sensor in the vehicle gravity direction; a slope value is derived based on the first vertical vector G and the second vertical vector Gse.
本发明涉及一种道路坡度测量方法,所述方法包括:在第一时刻,获得车载传感器在传感器坐标系中的垂直方向上的第一垂直矢量G;在第二时刻,获得所述传感器在所述传感器坐标系中的垂直方向上的第二垂直矢量Gse;基于所述传感器在车辆重力方向上的矢量数值变化来得出坡度方向;基于所述第一垂直矢量G和所述第二垂直矢量Gse来得出坡度值。
