The invention relates to an automobile instrument screen abnormity processing method and an automobile instrument, and the processing method comprises the following processing steps: S1, enabling an automobile instrument main control chip to send specific data to a screen display control chip, and enabling a screen to display the specific data; s2, periodically reading a specific data value from adisplay control chip register to a main control chip register; s3, periodically comparing the sent data with the received data by the main control chip, and judging whether the current working stateof the screen is normal or not; s4, if the abnormality occurs, the main control chip operates a screen power supply port to perform power-off and power supply operations; and S5, sending the page databefore power failure and the latest specific data to the display control chip, so that the screen is restored to the previous display page and keeps a normal working state. The invention discloses anautomobile instrument and a method for processing screen abnormity of the automobile instrument. The invention provides an automatic recovery mechanism for the abnormal state of the screen, the reliability of the instrument is improved, and the safety of the whole vehicle is ensured.

    本发明涉及一种汽车仪表屏幕异常的处理方法及汽车仪表,该处理方法包括以下处理步骤:S1、汽车仪表主控芯片发送特定数据到屏幕显控芯片,使屏幕显示特定数据;S2、周期性从显控芯片寄存器中读取特定数据值到主控芯片寄存器;S3、主控芯片周期性地对发送和接收的数据进行比对,判定屏幕当前的工作状态是否正常;S4、如异常出现,所述主控芯片则操作屏幕供电端口进行断电和供电操作;S5、将断电前的页面数据和最新特定数据发送至所述显控芯片,使屏幕恢复到之前显示页面并保持正常的工作状态。一种汽车仪表,采用该汽车仪表屏幕异常的处理方法。本发明提供了对于屏幕异常状态的自动恢复机制,提高了仪表的可靠性,保证了整车的安全性。
