The invention discloses an anti-collision early warning method for a semi-trailer inner wheel difference area based on double gyroscopes, which comprises the following steps of: firstly, respectively mounting a gyroscope module and a millimeter-wave radar on a tractor and a trailer which are positioned on the same side, wherein the gyroscope modules are used for measuring angular velocities and angles of a tractor body and a trailer body when the tractor body and the trailer body turn; the millimeter-wave radar on the tractor is arranged behind the millimeter-wave radar on the trailer, the millimeter-wave radar on the tractor is used for detecting the lateral front area of the vehicle, the millimeter-wave radar on the trailer is used for detecting the lateral rear area of the vehicle, and the detection areas of the two millimeter-wave radars intersect partially. Then the gyroscope module and the millimeter wave radar are connected with the main control module, the main control module is connected with an OBD interface of a vehicle, the real-time running speed of the vehicle is read, the inner wheel difference value of the semitrailer is calculated in real time according to the measured angular speed and angle data, and if the millimeter wave radar detects that an obstacle exists in an inner wheel difference early warning area, early warning is given out.

    本发明公开了一种基于双陀螺仪的半挂车内轮差区域防碰撞预警方法,先在位于同一侧的牵引车和挂车上均分别安装一只陀螺仪模块和一只毫米波雷达,其中陀螺仪模块用于测量牵引车车体和挂车车体转弯时的角速度和角度,将牵引车上的毫米波雷达设置位于挂车上毫米波雷达的后方,牵引车上的毫米波雷达用于探测车辆侧前方区域,挂车上的毫米波雷达用于探测车辆侧后方区域,两个毫米波雷达的探测区域部分相交,然后将陀螺仪模块和毫米波雷达与主控模块相连,主控模块连接车辆的OBD接口,读取车辆行驶的实时速度,并根据测得的角速度和角度数据,实时计算出半挂车的内轮差值,若毫米波雷达检测到内轮差预警区域内有障碍物存在时,则发出预警。
