The embodiment of the invention discloses a reverse overtaking collision early warning method, which comprises the following steps: when an original distance is greater than a safe distance, acquiring operation parameters of a current vehicle, a first target vehicle and a second target vehicle to be overtaken on a current lane; according to the operation parameters, the driving time of the current vehicle exceeding the second target vehicle in each stage is obtained; and obtaining the total driving distance between the current vehicle and the first target vehicle according to the driving time and the operation parameters, and carrying out reverse overtaking collision early warning according to the original distance and the total driving distance. A reverse overtaking process is decomposed into three stages of a stage of changing from a current lane to a reverse lane, a stage of driving on the reverse lane and a stage of returning from the reverse lane to the current lane to carry out overtaking analysis, and actual conditions such as the speed and the acceleration of vehicles are considered in the overtaking process instead of defaulting that each vehicle is driven at a constant speed. Therefore, collision early warning based on different stages according to actual driving conditions is more accurate.
本发明实施例公开了一种逆向超车碰撞预警方法,包括:当原始距离大于安全距离时,获取当前车辆、第一目标车辆以及当前车道上待超车的第二目标车辆的运行参数;根据运行参数获取当前车辆超越第二目标车辆在各阶段的行驶时间;根据行驶时间和运行参数获取当前车辆和第一目标车辆的总行驶距离,并根据原始距离和总行驶距离进行逆向超车碰撞预警。通过将逆向超车过程分解成从当前车道变道至逆向车道阶段、逆向车道行驶阶段和从逆向车道返回至当前车道阶段三个阶段进行超车分析,并且在超车过程中考虑了车辆的速度和加速度等实际情况,而不是将各车辆默认为匀速行驶,从而使得基于不同阶段根据实际行驶情况所进行的碰撞预警更加精准。
