The invention discloses a vehicle-mounted combination instrument assembly clock display method and system. The method comprises the steps that a vehicle-mounted communication controller assembly receives clock information in an external calibration signal; the clock information is converted into a CAN signal through a CAN protocol, and the CAN signal is sent to the combination instrument assembly; the combination instrument assembly compares whether the current display time is deviated from the received clock information or not; if no deviation exists, the display time of the combination instrument assembly is not updated; if deviation exists, the display time of the combination instrument assembly is updated, the received clock information serves as the current display time of the combination instrument assembly, and the combination instrument automatically conducts timing after updating.

    本发明公开了一种车载组合仪表总成时钟显示方法及系统,步骤包括:车载通信控制器总成接收外部校准信号中的时钟信息;通过CAN协议将时钟信息转化为CAN信号发送给组合仪表总成;组合仪表总成比较其当前显示时间与其接收的时钟信息是否有偏差;若无偏差,则组合仪表总成的显示时间不更新;若有偏差,则更新组合仪表总成的显示时间,将接收到的时钟信息作为组合仪表总成的当前显示时间,更新后由组合仪表自行计时。
