The invention relates to a vehicle clock synchronous display method. The technical problem to be solved is how to ensure that the time display of each display screen of a vehicle is accurate and consistent. The method comprises the following steps: (1) a 4G telephone card is built in a vehicle-mounted T-BOX and is connected with a GPS antenna, a central control large screen is connected with the T-BOX through a USB1, and the central control large screen is also connected with an instrument through a USB2; the T-BOX firstly analyzes time information through 4G and a GPS to obtain time 1 and sends the time 1 to a CAN network, and a central control large screen and an instrument obtain the time 1 through the CAN network and display the time 1 on the screen; and (2) when the time signal on the CAN network is lost, the central control large screen obtains the time information of 4G and GPS signals through the USB1 and performs time analysis to obtain time 2, the central control large screen displays the analysis time after successful analysis, and the time 2 is synchronously transmitted to the instrument through the USB2 to be displayed at the same time.

    本发明涉及一种车辆时钟同步显示方法。解决的技术问题是如何保证车辆各显示屏幕的时间显示准确且一致。所述方法包括如下步骤:(1)车载T‑BOX内置4G电话卡并连接GPS天线,中控大屏通过USB1与T‑BOX相连接,中控大屏还通过USB2与仪表相连接;T‑BOX首先通过4G和GPS解析时间信息得到时间1,并把时间1发送到CAN网络上,中控大屏、仪表通过CAN网络获取时间1并显示在屏幕上;(2)当CAN网络上的时间信号丢失时,中控大屏通过USB1获取4G和GPS信号自身的时间信息并进行时间解析,得到时间2,解析成功后中控大屏显示解析时间,同时把时间2通过USB2同步传送给仪表进行显示。
