The invention provides a method and system for preventing rear-end collision of an automobile, and relates to the technical field of vehicle engineering. Comprising the following steps: positioning real-time positions of a vehicle and a target vehicle, and obtaining a real-time circumcircle range of the vehicle and the target vehicle; the distance value between the circumcircle range of the vehicle and the circumcircle range of the target vehicle is calculated, and the collision condition between the target vehicle and the vehicle is determined according to the distance value and the safety distance corresponding to the road type where the vehicle is located; and when the collision risk exists between the target vehicle and the vehicle, performing anti-collision control on the vehicle. The distance between the vehicle and the front vehicle is monitored in real time by calculating the circumcircle of the vehicle and the front vehicle, meanwhile, the taillights of the front vehicle are recognized in real time, and rear-end collision caused after sudden braking of the front vehicle is avoided.
本发明提出了汽车防止追尾碰撞的方法及系统,涉及车辆工程技术领域。包括定位本车车辆和目标车辆的实时位置,获取本车车辆与目标车辆的实时外接圆范围;计算本车车辆外接圆范围与目标车辆外接圆范围之间的距离值,根据距离值与所处道路类别对应的安全距离,确定所述目标车辆与所述本车车辆之间的碰撞情况;当所述目标车辆与所述本车车辆之间存在碰撞风险时,对所述本车车辆进行防碰撞控制。本发明通过计算本车与前车外接圆的方式实时监测与前车的距离,同时对前车尾灯进行实时识别,避免在前车突然急刹之后造成追尾。
