The invention discloses a clock synchronization method for an automobile instrument and an automobile machine, which comprises the following steps of: after the automobile machine and the instrument are electrified, comparing the system time of the automobile machine with the system time of the instrument, and when the difference between the system time of the automobile machine and the system time of the instrument is less than a set time threshold value, timing the automobile machine and the instrument by adopting respective system time; otherwise, unifying the system time of the vehicle machine and the instrument. The method has the advantages that the method is simple and fast, the method can be integrated in the vehicle machine and the instrument through software, unification and updating of the time and the instrument are fast, hardware is not added, only software updating is needed, cost is low, and applicability is high.

    本发明公开了一种汽车仪表和车机的时钟同步方法,在车机和仪表上电后,对车机的系统时间和仪表的系统时间进行比对,当两者的系统时间相差小于设定时间阈值时,车机和仪表各采用各自的系统时间计时;否则将车机和仪表两者的系统时间统一。本发明的优点在于:方法简单快速,可以通过软件的方式将本申请的方法集成在车机和仪表中,快速时间两者时间的统一和更新,无硬件增加,仅需要软件更新,成本低且适用性强。
