The fuel gauge is an indicator on the dashboard of the automobile for displaying the current fuel quantity of the automobile. It is typically a circular pointer pointing to a corresponding location on a dial indicating the percentage of the current oil. The principle of oil mass measurement is generally based on the buoyancy method. The buoyancy method is a method of calculating the amount of oil by measuring the weight of the oil in the tank. The more the amount of oil in the tank, the greater the weight of the oil and the greater the buoyancy in the tank. By measuring the buoyancy in the tank, the amount of oil delivered can be calculated. Modern motormeter fuel level measurements also make it possible to use electronic sensors to calculate the fuel level by measuring the volume of the fuel in the tank. Some modern automobiles are also equipped with electronic fuel gauges, which can display the percentage of the current fuel more accurately, and high-precision fuel display brings about some pain points: pain spot 1: when the vehicle runs on a bumpy road, the oil level can shake, and the oil level can also fluctuate; pain spot 2: each time ADC sampling has certain error, the calculated oil quantity value has jitter; pain spot 3: on uphill and downhill slopes, deviations may also occur in the fuel gauge.

If the standard deviation of the data in the data pool is smaller than n2, the data pool is relatively stable, the data is reliable, and the average value is updated to the display picture as the oil value. If the standard deviation of the data in the data pool is greater than or equal to N2 and less than or equal to N1, indicating that the data has certain fluctuation, discarding the maximum value and the minimum value in the data pool, and continuously collecting the resistance value of the oil quantity sensor until the multiple of N is reached again, and executing the step 3 again. If the total number of data in the data pool reaches M, to limit excessive CPU power consumption, some of the earliest data is discarded until the number of data in the data pool is less than M. n1, n2, N, M need to be determined experimentally according to the actual situation.
In some embodiments, the method further comprises: and if the state represents that the oil quantity sensor works abnormally, generating abnormal prompt information.
