The invention discloses an abnormal reset processing method of a microcontroller. The method comprises the steps that after the microcontroller is reset, reset information of the microcontroller is determined, and the reset information comprises one of normal reset information and abnormal reset information; if the reset information is abnormal reset information, obtaining display information displayed by the combination instrument before the microcontroller is reset; in the initialization process of the combination instrument, display information is displayed on the combination instrument; and after the combination instrument is initialized, changing the display information displayed on the combination instrument into the current driving information. According to the technical scheme, after the microcontroller is reset, the reset information of the microcontroller is determined, then the display information is obtained based on the abnormal reset information, and then the display information displayed on the combination instrument is changed into the current driving information, so that the situation that after the microcontroller is reset abnormally, the current driving information is displayed on the combination instrument is avoided. The problem that a driver cannot obtain driving information from the combination instrument for a long time is solved, convenience is provided, and driving safety is improved.
本发明公开了一种微控制器的异常复位处理方法。该方法包括:在微控制器复位后,确定微控制器的复位信息,复位信息包括以下之一:正常复位信息和异常复位信息;若复位信息为异常复位信息,则获取微控制器复位前的组合仪表所显示的显示信息;在组合仪表初始化的过程中,在组合仪表显示显示信息;在组合仪表初始化后,将组合仪表上显示的显示信息变更为当前行车信息。上述技术方案中,通过在微控制器复位后,确定微控制器的复位信息,进而基于异常复位信息,获取显示信息,进而将组合仪表上显示的显示信息变更为当前行车信息,避免了在微控制器异常复位后,驾驶员有很长时间不能从组合仪表获取行车信息的问题,提供了便利,提升了行车安全性。
