Vehicle refueling moment identification method, device and equipment

The invention discloses a vehicle refueling moment identification method, device and equipment. The method comprises the following steps: firstly, acquiring driving data of a target vehicle; screening and deleting abnormal data from the data to obtain processed data; screening out data of which the difference between the liquid level of the oil tank at the next moment and the liquid level of the oil tank at the previous moment is greater than or equal to a second preset threshold value in adjacent moments from the processed data, determining the next moment as a primarily-selected refueling moment, and further calculating a first standard deviation of the liquid level of the oil tank corresponding to N moments before the primarily-selected refueling moment; calculating a second standard deviation of the liquid level of the oil tank corresponding to the primary refueling moment and the subsequent N moments of the primary refueling moment; when it is judged that the first standard deviation and the second standard deviation are both not larger than a third preset threshold value, the primary refueling moment is recognized as the final refueling moment of the target vehicle; in this way, by recognizing and deleting the abnormal data in advance and introducing standard deviation calculation, the recognition accuracy of the vehicle refueling moment is improved.
