The invention discloses an automatic driving fleet marshalling method and system based on a PTP protocol. The method comprises the following steps: obtaining time deviation of each vehicle of an automatic driving fleet relative to a head vehicle and time delay of an information transmission link between the head vehicle and the automatic driving vehicle; and according to the obtained time deviation of each vehicle of the automatic driving fleet relative to the head vehicle and the time delay of the information transmission link between the head vehicle and the automatic driving vehicle, synchronously adjusting the time of each vehicle of the automatic driving fleet. According to the automatic driving vehicle team marshalling method based on the PTP protocol, time synchronization adjustment is carried out on the automatic driving vehicle based on the obtained time deviation and the time delay of the information transmission link between the head vehicle and the automatic driving vehicle, high-precision time synchronization of the automatic driving vehicle and the head vehicle is achieved, and the time synchronization efficiency is improved. And automatic driving vehicle formation is carried out on the basis of time synchronization.

    本发明公开了基于PTP协议的自动驾驶车队编组方法及系统,方法包括以下步骤:获取自动驾驶车队各车辆相对于头车的时间偏差以及头车和自动驾驶车辆之间的信息传输链路的时间延迟;根据获取的自动驾驶车队各车辆相对于头车的时间偏差以及头车和自动驾驶车辆之间的信息传输链路的时间延迟,同步调整自动驾驶车队各车辆时间。本申请提供的基于PTP协议的自动驾驶车队编组方法,基于获取的时间偏差以及头车和自动驾驶车辆之间的信息传输链路的时间延迟,对自动驾驶车辆进行时间同步调整,实现自动驾驶车辆和头车的高精度时间同步,并在时间同步的基础上进行自动驾驶车辆编队。
