The invention provides a vehicle control method, system and device for an adaptive cruise system and a medium. The method comprises the steps that vehicle information of a vehicle following target is obtained in real time; if it is judged that the car-following target is lost, the speed and the car distance at the moment before the car-following target is lost are kept, and a period of prediction time is set from the loss moment; according to the speed and the vehicle distance at the moment before the vehicle-following target is lost, the predicted target vehicle speed and the predicted vehicle distance at the current moment are obtained; the current vehicle speed of the vehicle is compared with the current predicted vehicle speed of the target vehicle, the set target vehicle distance is compared with the current predicted vehicle distance, and a comparison result is obtained; the comparison result is matched with a set control condition, and the vehicle is controlled to be accelerated, decelerated or at a constant speed; if it is judged that the current moment exceeds the predicted time, the vehicle is controlled to enter a constant-speed cruise mode from a vehicle following running mode, and meanwhile the vehicle acceleration and the vehicle Jerk are limited to be calibration values. The collision risk can be effectively reduced, and the system safety is improved.

    本发明提供一种用于自适应巡航系统的车辆控制方法、系统、设备及介质,方法包括:实时获取跟车目标的车辆信息;若判断跟车目标丢失,则保持跟车目标丢失前一时刻的速度和车距,并从丢失时刻起设定一段预测时间;根据跟车目标丢失前一时刻的速度和车距,获得当前时刻的预测目标车车速和预测车距;将自车当前车速与当前的预测目标车车速对比,将设定的目标车距与当前的预测车距对比,获得对比结果;将对比结果与设定的控制条件进行匹配,控制车辆加速、减速或匀速;若判断当前时刻超出预测时间,则控制车辆从跟车行驶模式进入定速巡航模式,同时将车辆加速度和车辆Jerk限制为标定值。本发明能够有效降低碰撞风险,提升系统安全性。
