The invention provides a vehicle time synchronization method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring reference time, setting the reference time as service plane time, and synchronizing the service plane time to each device in a service plane system; and in different operation stages of the domain controller, setting the service plane time or the first crystal oscillator time corresponding to the domain controller as computational domain time, and synchronizing the computational domain time to each sensor. According to the method, when the reference data jumps due to different T-BOX time service mechanisms, the calculation domain time of the domain controller does not jump along with the service surface time, so that the running stability of the automatic driving function of the vehicle is ensured, and an automatic driving fault is prevented.

    本发明提供一种车辆时间同步的方法、装置、车辆及存储介质。该方法包括:获取基准时间,并将基准时间设置为业务面时间,将业务面时间同步至业务面系统内的各设备;在域控制器的不同运行阶段,将业务面时间或域控制器对应的第一晶振时间设置为计算域时间,并同步给各传感器。本发明能够在基准数据由于T‑BOX授时机制的不同发生跳变时,域控制器的计算域时间可以不随业务面时间进行跳变,从而保证车辆自动驾驶功能运行的稳定性,防止自动驾驶故障。
