The invention provides an automatic driving overtaking control method and system, and relates to the technical field of automatic driving. The method comprises the steps that receiving vehicle surrounding environment information collected by a vehicle-mounted environment perception sensor; judging whether the distance to a preceding vehicle is smaller than a specified distance or not; if the distance is smaller than the specified distance, keeping self-adaptive cruise; if the distance is greater than or equal to the specified distance, inputting, by a domain controller, the vehicle surroundingenvironment information and vehicle driving state information into an overtaking intention model for analysis and calculation, wherein the vehicle surrounding environment information comprises a front vehicle driving state, a left front vehicle driving state and a left rear vehicle driving state; if an overtaking intention exists, judging whether an overtaking condition is met or not; if the overtaking condition is met, sending, by the domain controller, a signal to a vehicle executing mechanism to enter an overtaking state; and after overtaking is completed, ending the overtaking state. According to the invention, the problem that the automatic driving overtaking behavior is not safe is solved, and the driving safety is improved.
本发明提供一种自动驾驶超车控制方法及系统,涉及自动驾驶技术领域。该方法包括:接收车载环境感知传感器采集的车辆周围环境信息;判判断与前车距离距离是否小于指定距离;若小于指定距离,保持自适应巡航;若大于等于指定距离,域控制器把所述车辆周围环境信息和本车辆行驶状态信息输入超车意图模型,进行分析计算;其中,所述车辆周围环境信息包括:前车行驶状态、左前车行驶状态和左后车行驶状态;若存在超车意图,判断是否满足超车条件;若满足超车条件,域控制器发信号给车辆执行机构,进入超车状态;超车完成后,结束超车状态。本发明中,解决了自动驾驶超车行为不安全的问题,提高驾驶安全性。
