The invention discloses an automatic obstacle avoidance method and system for an intelligent network connection passenger vehicle. The method specifically comprises the steps that whether an obstacle exists in a target lane or not is monitored in real time, and the collision time TTC of a target vehicle and the obstacle is calculated; monitoring whether an adjacent lane of the target lane has an obstacle or not in real time, and calculating whether the adjacent lane has a lane changing space or not and whether the adjacent lane can change the lane emergently or not; according to the collision time, the fact that adjacent lanes have lane changing spaces and whether the adjacent lanes can change the lanes emergently or not, the modes of automatically controlling lane changing, triggering an automobile intelligent auxiliary lane changing system ALC, triggering an emergency lane changing obstacle avoidance system AES and triggering an automatic emergency braking system AEB are adopted in sequence; according to the method, the target vehicle is controlled to change lanes or be braked emergently, so that the situation that an AEB automatic emergency braking system is activated to bring great influence on driving judgment and riding comfort of a driver can be avoided as much as possible, and the target vehicle can be prevented from colliding with a vehicle in an adjacent lane.
本发明公开了一种智能网联乘用车自动避障方法及系统,具体包括:实时监测目标车道是否有障碍物以及计算目标车辆与障碍物相碰撞时间TTC;实时监测目标车道的相邻车道是否有障碍物,并计算相邻车道是否有变道空间以及相邻车道是否可以紧急变道;并根据碰撞时间,相邻车道具有变道空间以及相邻车道是否可以紧急变道,依次采用自主操纵变道,触发汽车智能辅助变道系统ALC,触发紧急变道避障系统AES,以及触发自动紧急制动系统AEB的方式;控制目标车辆变道或者紧急制动,既能尽量避免激活AEB自动紧急制动系统,给驾驶员的驾驶判断和乘坐舒适性带来极大的影响,又可以避免目标车辆与相邻车道内的车辆相碰撞。
