The invention discloses a vehicle following time interval control method and device of an automatic driving vehicle, the vehicle and a medium, and the method comprises the steps: collecting a first target vehicle following time interval corresponding to a current vehicle following time interval gear of the vehicle under the condition that the vehicle is detected to be in a self-adaptive cruise working condition, and recognizing environment information of an environment where the vehicle is located, the method comprises the steps of acquiring environment information of a vehicle to obtain a weather category and/or current visibility corresponding to the environment information, determining a weather severity level of the environment information, correcting a first target vehicle following time interval by using a second target vehicle following time interval corresponding to the weather severity level, obtaining a third target vehicle following time interval of the vehicle, and controlling the vehicle to run in a vehicle following manner according to the third target vehicle following time interval. According to the embodiment of the invention, when the vehicle is in the self-adaptive cruise working condition, the weather severity level can be determined according to the weather category and/or the current visibility, and the following time interval of the vehicle is corrected by using the following time interval corresponding to the weather severity level, so that the applicability and reliability of the following time interval control are improved.

    本申请公开了一种自动驾驶车辆的跟车时距控制方法、装置、车辆及介质,其中,方法包括:在检测到车辆处于自适应巡航工况的情况下,采集车辆的当前跟车时距档位对应的第一目标跟车时距,并识别车辆所处环境的环境信息,以获取环境信息对应的天气类别和/或当前能见度,从而确定环境信息的天气恶劣等级,利用天气恶劣等级对应的第二目标跟车时距修正第一目标跟车时距,得到车辆的第三目标跟车时距,以根据第三目标跟车时距控制车辆跟车行驶。本申请实施例可以在车辆处于自适应巡航工况时,根据天气类别和/或当前能见度确定天气恶劣等级,利用天气恶劣等级对应的跟车时距修正车辆的跟车时距,提升了跟车时距控制的适用性和可靠性。
