The invention provides a vehicle instrument mileage updating method and system, and the method comprises the steps: receiving a first mileage signal and a second mileage signal which are correspondingly transmitted by a BCM and an EMS respectively when the replacement of an instrument is completed; a first difference value between the first mileage value and the second mileage value is calculated, and whether the first difference value is smaller than a first preset threshold value or not is judged; if yes, comparing the maximum value between the first mileage value and the second mileage value with a third mileage value recorded in the current instrument so as to correspondingly calculate a second difference value; judging whether the second difference value is greater than a second preset threshold value; if it is judged that the second difference value is larger than the second preset threshold value, the third mileage value is replaced with the maximum value between the first mileage value and the second mileage value, and mileage updating is completed. In this way, updating of the mileage of the instrument after current replacement can be simply and rapidly completed, the use experience of a user is improved, and the method is suitable for large-scale application and popularization.

    本发明提供了一种车辆仪表里程更新方法及系统,该方法包括当仪表更换完成时,接收BCM和EMS分别对应发送的第一里程信号以及第二里程信号;计算出第一里程值与第二里程值之间的第一差值,并判断第一差值是否小于第一预设阈值;若是,则将第一里程值与第二里程值之间的最大值与当前仪表中记录的第三里程值进行比对,以对应计算出第二差值;判断第二差值是否大于第二预设阈值;若判断到所述第二差值大于所述第二预设阈值,则将所述第一里程值与所述第二里程值之间的最大值替换掉所述第三里程值,以完成里程的更新。通过上述方式能够简单、快速的完成当前更换后仪表里程的更新,提升了用户的使用体验,适用于大范围的推广与使用。
