Problems solved by technology
However, because the collected fuel output is not very accurate, there is also an error between the fuel volume change estimated based on this technical solution and the actual fuel volume change of the vehicle.
[0005] The third technical solution is to establish a fuel consumption formula based on the vehicle's speed or acceleration to calculate the fuel quantity change of the vehicle. However, due to the complexity of the vehicle's driving environment, the vehicle's speed or acceleration and other variables are easily affected by the external environment. Variables such as vehicle speed or acceleration are inaccurate, which may lead to inaccurate fuel consumption formulas based on vehicle speed or acceleration variables, and the difference between the fuel volume change estimated based on the fuel consumption formula and the actual fuel volume change of the vehicle There is an error
[0006] To sum up, there is an error between the fuel quantity change of the vehicle estimated based on the existing technical scheme and the actual fuel quantity change of the vehicle

The invention provides a method and a device for determining oil mass change of a vehicle and a computer readable storage medium, relates to the technical field of vehicles, and can reduce an error between the estimated oil mass change of the vehicle and the actual oil mass change of the vehicle. The method comprises the steps that first pressure borne by a base of the vehicle fuel tank at a first moment, second pressure borne by the base of the vehicle fuel tank at a second moment and an included angle between the base of the vehicle fuel tank and the horizontal plane are obtained; according to the first pressure, the second pressure and the included angle between the base of the vehicle fuel tank and the horizontal plane, the first fuel quantity change volume of the vehicle fuel tank in the target time period is determined, and the target time period is the time period between the first moment and the second moment.
Description
technical field [0001] The present application relates to the technical field of vehicles, and in particular to a method, a device, and a computer-readable storage medium for determining a change in fuel quantity of a vehicle. Background technique [0002] In order to determine the change in the fuel quantity of the vehicle (ie fuel consumption), there are currently three solutions: [0003] The first technical solution is to measure the liquid level value of the fuel tank based on the oil rod sensor, mechanical buoy and other equipment, and determine the change of the fuel volume of the vehicle through the difference of the liquid level value. However, because fuel tanks with different shapes, different types of fuels and fuels with different densities have different fuel volumes at the same liquid level, there is an error between the fuel volume change estimated based on this technical solution and the actual fuel volume change of the vehicle. [0004] The second technica...
