The invention relates to a curve target screening method for adaptive cruise and a storage medium, and the method comprises the steps: collecting a historical track of a cruise target vehicle under the position of the vehicle during the adaptive cruise of the vehicle; the historical track information is updated according to the changing position of the vehicle in the running process every preset time; when the cruise target vehicle enters the curve and is located outside the predicted trajectory of the vehicle, whether the cruise target vehicle continues to be used as a target to follow the vehicle or not is determined according to the transverse distance between the vehicle and the historical trajectory; the time after the new target appears is timed, and the acceleration maintaining time of the hold mode is adjusted according to different lasting time when the target appears, so that the problem that the hold mode slows down for a long time due to mistaken touch is avoided; according to the method, the target vehicle can be stably followed in the process of entering the curve without a lane line, and the comfort of the self-adaptive cruise function is improved.
本发明涉及一种自适应巡航的弯道目标筛选方法及存储介质,其在本车自适应巡航时,采集巡航目标车辆在自车位置下的历史轨迹;每隔预定时间将所述历史轨迹信息根据行驶中变化的自车位置进行更新;在所述巡航目标车辆进入弯道且位于自车预测轨迹外时,依据自车与历史轨迹的横向距离确定是否继续将所述巡航目标车辆作为目标以跟随行驶;其还通过对新目标出现后的时间进行计时,根据目标出现持续的不同时间对hold模式维持加速度的时间进行调整,从而避免误触导致hold模式造成较长时间减速的问题;本发明实现了在无车道线路况且进入弯道的过程中稳定跟随目标车辆,并提升了自适应巡航功能的舒适性。
