The first set threshold value, the second set threshold value and the third set threshold value are sequentially increased, and the second time threshold value, the first time threshold value and the third time threshold value are sequentially increased.
Optionally, the first set threshold is determined according to a maximum fueling speed, the second set threshold is determined according to a minimum fueling speed, the third set threshold is determined according to a maximum fueling speed, the first time threshold is determined according to a shaking time of the liquid level of the oil tank caused by opening or closing the oil tank door, and the second time threshold and the third time threshold are both determined according to the first time threshold.

S120, determining a calculated oil quantity coefficient according to the vehicle state; the calculated oil quantity coefficient is used for representing the speed of oil quantity change under a certain state of the vehicle.
The method introduces the concept of calculating the oil quantity coefficient, is used for representing the speed of oil quantity change under a certain state of the vehicle, and can calculate the oil quantity in a targeted manner according to different states so as to improve the accuracy of the subsequent oil quantity calculation.
Further, the determining the calculated oil quantity coefficient according to the vehicle state includes:
judging the state of the vehicle as self-checking, and determining the calculated oil quantity coefficient as 1;
judging the state of the vehicle to be idle, running or oil leakage, and determining the oil mass emptying time; determining and calculating an oil quantity coefficient according to the oil quantity emptying time; the calculated oil quantity coefficient is positively correlated with the time of the oil quantity emptying; under the idle speed, running or oil leakage state, the calculated oil quantity coefficient is smaller than 1;
judging the state of the vehicle as refueling, and determining the time of filling the fuel; determining and calculating an oil quantity coefficient according to the oil quantity filling time; the calculated oil quantity coefficient is positively correlated with the oil quantity filling time; in the refueling state, the calculated oil mass coefficient is larger than 1.
Wherein, "the calculated oil quantity coefficient is positively correlated with the time of the oil quantity drain" means that the calculated oil quantity coefficient increases with the increase of the time of the oil quantity drain, but is always smaller than 1. By "the calculated oil amount coefficient is positively correlated with the time of the oil amount filling" is meant that the calculated oil amount coefficient increases with the increase of the time of the oil amount filling, but is always greater than 1. The oil amount emptying time and the oil amount filling time can be determined according to vehicle history emptying data and vehicle history filling data, and can also be determined according to limit emptying time or limit filling time under different states. For idle conditions, the limit purge time is, for example, 4-5 hours; for driving conditions, the limit emptying time is, for example, 90-100min; for oil leakage conditions, the limit drain time is, for example, 20-25s; for the refuelling condition, the limit fill time is for example 20-25s.
The calculated oil amount coefficient is different in different vehicle states, and since the vehicle does not move in the self-test state, the oil consumption is minimum, and the liquid level in the oil tank is stable, it is determined that the collected oil amount is substantially equal to the calculated oil amount, and therefore the calculated oil amount coefficient in the self-test state is set to 1 in the present embodiment. In the idle speed, the driving state or the oil leakage state, the oil consumption speed is larger than that in the self-inspection state, so that the calculated oil quantity is judged to lag behind the collected oil quantity, and the calculated oil quantity coefficient is set to be smaller than 1. Similarly, the oil amount is increased in the refueling state, and the calculated oil amount lags behind the collected oil amount, so that the calculated oil amount coefficient is set to be greater than 1.

judging the state of the vehicle as flameout, and determining the display oil quantity as calculated oil quantity before flameout (namely, if the state of the vehicle is flameout, directly taking calculated oil quantity before flameout as the display oil quantity, wherein the calculated oil quantity before flameout refers to calculated oil quantity closest to flameout time);
judging the vehicle state as self-checking, and determining the display oil quantity as calculated oil quantity (namely, if the vehicle state is self-checking, the liquid level in the oil tank is stable, the calculated oil quantity is not changed greatly, and the calculated oil quantity is taken as the display oil quantity);
Judging the state of the vehicle to be idle, running or oil leakage, determining the display oil quantity to be calculated oil quantity, wherein the display oil quantity is smaller than the last display oil quantity (namely, if the state of the vehicle is idle, running or oil leakage, the display oil quantity is gradually reduced, and the calculated oil quantity is still used as the display oil quantity at the moment, but the premise is that the display oil quantity is smaller than the last calculation oil quantity, namely, the display oil quantity can not be increased in the above state and can only be reduced, so that the unreasonable jump of the display oil quantity is avoided);
the vehicle state is judged to be refueled, the display oil quantity is determined to be the calculated oil quantity, and the display oil quantity is smaller than the last display oil quantity (namely, if the vehicle state is refueled, the display oil quantity is gradually increased, and the calculated oil quantity is still taken as the display oil quantity at the moment, but the premise is that the display oil quantity is required to be larger than the last calculated oil quantity, that is, the display oil quantity cannot be reduced but only can be increased in the above state, so that the unreasonable jump of the display oil quantity is avoided).
It should be noted that the execution order of the steps in the present embodiment is only exemplary, and is not meant to be a representation that the steps can be performed in this order, for example, the steps S110 and S120 may be interchanged.
