The invention discloses a method and terminal for an automatic driving vehicle to intelligently select a following vehicle. The method comprises the following steps: detecting the number of lanes and vehicle road behaviors within a preset sight distance in each lane; scoring the vehicle driving stability according to the vehicle road section behaviors to obtain vehicles whose scores accord with a preset threshold value; and any vehicle with the score meeting a preset threshold value is selected to keep a safe distance for vehicle following driving. The monitoring system of the automatic driving vehicle is used for obtaining the number of lanes and the vehicle road section behaviors within the preset sight distance in each lane, analysis is carried out according to the vehicle road section behaviors of each lane, the vehicle driving stability is scored, unstable vehicles such as vehicles with frequent lane changing, overtaking and emergency braking behaviors are screened out, and the driving stability of the vehicles is improved. According to the method, data of vehicles running normally are obtained, one vehicle is selected to run along with the vehicle according to the safe distance, a proper vehicle following vehicle is found in complex road conditions, and the safety of automatic driving is improved.
本发明公开一种自动驾驶车辆智能选择跟驰车辆的方法及终端,检测车道数量以及每个车道中预设视距内的车辆路段行为;根据车辆路段行为对车辆驾驶稳定性进行评分,得到评分符合预设阈值的车辆;选择评分符合预设阈值的任一车辆保持安全距离进行跟车行驶。本发明利用自动驾驶车辆的监控系统获取车道数量以及每个车道中预设视距内的车辆路段行为,并根据每个车道的车辆路段行为进行分析,对车辆驾驶稳定性进行评分,筛除不稳定车辆,例如出现频繁变道、超车、紧急制动等行为的车辆,得到处于正常行驶车辆的数据,并选择其一按照安全距离进行跟车行驶,在复杂路况中寻找合适跟车车辆,提升自动驾驶的安全性。
