The invention discloses a data file verification method and device, electronic equipment, a vehicle and a storage medium, and relates to the technical field of file verification, and the method comprises the steps that before a controller is powered on, data files of all application programs in the controller are determined; calculating a first verification value of each data file; after the controller is powered on, calculating a second verification value of each data file; verifying the corresponding second verification values by using the first verification values, and recording the second verification values which do not pass the verification as abnormal verification values; after it is detected that the controller sends out a power-off signal, calculating a third verification value of each data file; verifying the corresponding third verification value by using each first verification value, and recording the third verification value which does not pass the verification as an abnormal verification value; and when the abnormal verification value is detected, triggering a coping strategy matched with the abnormal verification value. And each data file can be monitored in real time according to the check value of each data file before power-on, after power-on and in the power-off stage of the controller.
本申请公开了数据文件校验方法、装置、电子设备、车辆及存储介质,涉及文件校验技术领域,方法包括:在控制器上电前,确定控制器内各个应用程序的数据文件;计算各个数据文件的第一校验值;在控制器上电后,计算各个数据文件的第二校验值;利用各个第一校验值校验对应的第二校验值,记录未通过校验的第二校验值作为异常校验值;在检测到控制器发出下电信号后,计算各个数据文件的第三校验值;利用各个第一校验值校验对应的第三校验值,记录未通过校验的第三校验值作为异常校验值;当检测到异常校验值时,触发与异常校验值匹配的应对策略。根据控制器上电前、上电后和下电阶段各个数据文件的校验值,可实时监控各个数据文件。
