The invention relates to a vehicle-vehicle cooperative anti-collision early warning method based on driving behaviors, whichbelongs to the field of intelligent driving. The method is mainly completedby a vehicle-mounted terminal, a mobile terminal, embedded AI equipment and an in-vehicle camera. The method comprises the steps that firstly, the in-vehicle camera collects a driving video of a driver, the driving video of the driver is transmitted to embedded AI equipment through a USB, the embedded AI equipment identifies abnormal driving behaviors of the driver in the video, and the monitoredabnormal driving behaviors of the driver are transmitted to an OBU through Socket communication; then, the OBU obtains vehicle motion data of the main vehicle through a GPS/IMU module or CAN communication. According to the method, the accuracy of the vehicle safety distance model is improved by combining the influence of the abnormal driving behavior of the driver on the vehicle anti-collision early warning on the basis of sensing the vehicle within the beyond-visual-range range, so that the accuracy of the vehicle anti-collision early warning and the safety of vehicle driving and riding are improved.
本发明涉及一种基于驾驶行为的车车协同防撞预警方法,属于智能驾驶领域。该方法主要车载终端、移动终端、嵌入式AI设备以及车内摄像头完成。首先,车内摄像头采集驾驶员驾驶视频,通过USB将驾驶员驾驶视频传输到嵌入式AI设备,嵌入式AI设备对视频中驾驶员的异常驾驶行为进行识别,将监测到的驾驶员异常驾驶行为通过Socket通信传输至OBU;然后,OBU通过GPS/IMU模块或CAN通信获取主车车辆运动数据;该方法在对超视距范围内的车辆进行感知的基础上,结合驾驶员异常驾驶行为对车辆防撞预警的影响,提高车辆安全距离模型的准确性,从而提高了车辆防撞预警的准确性和车辆驾乘的安全性。
