The invention provides an automobile fuel tank low liquid level alarm method and system, electronic equipment and a storage medium, and the method comprises the following steps: obtaining a real-time resistance value of a fuel tank liquid level sensor when detecting that an engine stalls; when it is judged that the real-time resistance value is smaller than or equal to a first preset threshold value, the engine is driven to be restarted for first preset times; when the engine is started every time, 1 is added to the first counter to obtain a first cumulative number of times; when it is judged that the first accumulated number of times is equal to a first preset number of times and the engine is not started successfully, first alarm information is sent to a display device; the first alarm information is used for prompting an engine fault. According to the method, the real-time resistance value of the liquid level sensor is obtained and compared with the first preset threshold value, and the real reason of engine flameout is judged by restarting the engine for certain preset times, so that accurate alarm information is output, and wrong prompts about engine abnormity alarm are prevented from being sent out.

    本申请提供一种汽车油箱低液位报警方法、系统、电子设备及存储介质,所述方法包括如下步骤:检测到发动机熄火时,获取油箱液位传感器的实时阻值;判断所述实时阻值小于或等于第一预设阈值时,驱动发动机重启第一预设次数;发动机每次启动时,第一计数器累计加1,得到第一累计次数;判断所述第一累计次数等于第一预设次数,且发动机未启动成功时,发出第一报警信息至显示装置;所述第一报警信息用于提示发动机故障。本申请通过获取液位传感器的实时阻值并将其与第一预设阈值进行对比,以及结合对发动机重启一定预设次数来判断发动机熄火的真实原因,从而输出准确的报警信息,避免发出对发动机异常报警的错误提示。
