The invention discloses a vehicle turning radius prediction and early warning method based on high-precision positioning and 5G communication, and the method comprises the steps: enabling a vehicle to turn around a certain center point in a test site, receiving the GNSS positioning information based on a high-precision positioning vehicle-mounted positioning module, and obtaining the longitude and latitude coordinates, and then converting the latitude and longitude coordinates into plane coordinates by using an earth elliptic equation, and finally determining the turning radius of the vehicle through a scatter point fitting circle center method. On the basis, vehicle turning early warning is achieved. Based on a measurement model of a high-precision positioning and vehicle-mounted positioning device, a vehicle turning radius parameter is estimated, a vehicle driving track can be accurately positioned, and early warning can be performed in advance by combining an intelligent sensing system.
本发明公开一种基于高精度定位及5G通信的车辆转弯半径预测预警方法,转弯半径预测方法包括:汽车在测试场地围绕某一中心点转弯,基于高精度定位车载定位模块接收GNSS定位信息获得经纬度坐标,然后将经纬度坐标再利用地球椭圆方程转化为平面坐标,最后通过散点拟合圆心法,确定车辆转弯半径。在此基础上,车辆转弯预警。本发明基于高精度定位与车载定位装置的测量模型,对车辆转弯半径参数进行估计,可精准定位车辆行驶轨迹,结合智能传感系统可提前预警。
