The invention discloses an intersection collision early warning method and device based on vehicle-to-vehicle communication and a storage medium, and the method comprises the steps: obtaining the real vehicle data of a main vehicle, and collecting the real vehicle data of a remote vehicle in real time through a vehicle-mounted communication unit OBU of the main vehicle; the real vehicle data of the main vehicle and the real vehicle data of the remote vehicle are analyzed and compared through a calculation center, a dangerous target vehicle is screened out, and whether the main vehicle and the target vehicle have a collision risk or not is judged; if it is judged that the collision risk exists between the main vehicle and the target vehicle, collision early warning is conducted. According to the invention, when the two vehicles are judged to have the collision risk according to the real vehicle data of the main vehicle and the remote vehicle, collision early warning is carried out, so that the false alarm rate of early warning is effectively reduced; early warning and auxiliary braking are carried out according to different emergency situations, and the vehicle collision risk at the intersection is effectively relieved or avoided; and different early warning and auxiliary braking time can be determined according to the driving style selected by the driver, so that the driving experience of the driver is improved.
本发明公开了一种基于车车通信的交叉路口碰撞预警方法、装置和存储介质,所述方法包括:获取主车的实车数据,并通过所述主车的车载通信单元OBU实时采集远车的实车数据;通过计算中心对所述主车的实车数据和所述远车的实车数据进行分析比对,筛选出危险的目标车辆,并判断主车与所述目标车辆是否存在碰撞风险;若判定所述主车与所述目标车辆存在碰撞风险,则进行碰撞预警。本发明根据主车和远车的实车数据判定两车存在碰撞风险时,则进行碰撞预警,有效降低了预警的误报率;根据不同的紧急情况进行预警和辅助制动,有效地减缓或避免交叉路口的车辆碰撞风险;还可根据驾驶员选定的驾驶风格,确定不同的预警和辅助制动的时间,提高驾驶员的驾驶体验。
