The invention designs an early warning method for preventing collision in a side blind area of a vehicle. The early warning method comprises the following steps: S1, acquiring real-time driving information of the vehicle; s2, when it is judged that the vehicle is in a steering state, an inner wheel difference area of the vehicle in the current state is calculated in real time according to the real-time driving information; s3, determining a blind area detection region ROI according to the inner wheel difference region and a detection range of an obstacle detection sensor; s4, according to the determined blind area detection region ROI, obstacle detection is carried out; and step S5, when it is determined that there is an obstacle in the blind area detection region ROI, performing lateral blind area anti-collision early warning in the steering direction. The method comprises the following steps: determining a first intersection point of a vehicle running speed direction horizontal vertical line or a vehicle head horizontal direction along a long line and an inner wheel difference area according to vehicle real-time driving information; and according to the connecting line between the first intersection point and the obstacle detection sensor, the blind area detection region ROI in the detection range can be determined in real time, and the technical effect of safety monitoring is achieved.

    本申请设计了一种车辆侧方盲区防碰撞的预警方法,包括:步骤S1、获取车辆实时驾驶信息;步骤S2、当判定所述车辆处于转向时,根据所述实时驾驶信息实时计算所述车辆当前状态下的内轮差区域;步骤S3、根据所述内轮差区域与障碍物探测传感器的探测范围,确定盲区检测区域ROI;步骤S4、根据确定出的所述盲区检测区域ROI,进行障碍物检测;步骤S5、当判定所述盲区检测区域ROI内存在障碍物时,进行转向方向的侧方盲区防碰撞预警。本申请根据车辆实时驾驶信息确定与车辆行驶速度方向水平垂线或车头水平方向的沿长线与内轮差区域的第一交点;并根据第一交点与障碍物探测传感器之间的连线,能够实时确定探测范围内的盲区检测区域ROI,实现安全监控的技术效果。
