The invention discloses a method for controlling a vehicle to automatically enter and exit a tunnel based on a drive-by-wire chassis, and relates to the field of vehicle intelligent driving. Determining whether a condition for entering the tunnel exists or not based on tunnel height limitation and internal and external congestion conditions; when the condition of entering the tunnel is met and the distance between the vehicle and the tunnel entrance is smaller than a first distance threshold value, the vehicle is controlled to drive into the tunnel at the speed lower than the tunnel limit speed; ensuring that the vehicle speed is always kept below the tunnel speed limit in the tunnel, and adjusting the vehicle speed and the driving path in real time according to the driving state of the adjacent vehicle; when the distance between the current vehicle and the tunnel exit is smaller than a second distance threshold value, reminding a driver that the vehicle is about to drive out of the tunnel, and when the current vehicle drives out of the tunnel and the distance between the current vehicle and the tunnel exit is larger than a third distance threshold value, entering a manual driving mode; the vehicle speed and the driving path of the vehicle are adjusted in real time according to the driving state of the adjacent vehicle, and the driving safety of the vehicle in a tunnel with narrow space and insufficient light can be improved.
本发明公开一种基于线控底盘的控制车辆自动进出隧道的方法,涉及车辆智能驾驶领域,方法包括:获取隧道信息;基于隧道限高和内外拥堵情况,确定是否具备进入隧道的条件;当具备进入隧道的条件且与隧道入口的距离小于第一距离阈值时,控制车辆以低于隧道限速的速度驶入隧道;在隧道内确保车速始终保持在隧道限速以下,并且根据相邻车辆的行驶状态实时调整车速与行驶路径;当当前车辆与隧道出口的距离小于第二距离阈值时,提醒驾驶员车辆即将驶出隧道,当当前车辆驶出隧道且与隧道出口的距离大于第三距离阈值时,进入手动驾驶模式;本发明根据相邻车辆的行驶状态实时调整车辆的车速与行驶路径,可提高车辆在空间狭小、光线不足的隧道内行驶安全性。
