The invention provides a system, method and device for reminding fuel amount of a fuel tank, and relates to the technical field of vehicle refueling. The system for reminding the fuel amount of the fuel tank includes a first obtaining module, a calculation module, a second obtaining module and a determination module; the first obtaining module obtains the first gasoline density Rho1 correspondingto the highest temperature on that day; the calculation module calculates the density ratio beta according to the pre-stored second gasoline density Rho2 of a petrol station; the calculation module then calculates the maximum fuel storage amount V1 of the fuel tank according to the volume V0 of the fuel tank and the density ratio beta; the second obtaining module obtains the oil consumption amountV2 required by the driving distance K, and the determination module determines the threshold value V3 at the time of stopping refueling. The problem that variation of temperature difference causes fuel leakage and deformation of the fuel tank can be solved, and the fuel tank is thus protected.
Description
technical field [0001] The invention relates to the technical field of vehicle refueling, in particular to a system, method and device for reminding the refueling amount of a fuel tank. Background technique [0002] At present, the problem of fuel tank filling volume has become one of the important problems that automobile manufacturers want to solve, especially in areas with large temperature difference between day and night, if the fuel tank is filled too much when the temperature is low, the temperature rises The volume of oil in the fuel tank increases after high, which may easily cause excess oil to leak and damage the carbon tank; moreover, the increased volume of oil may easily deform the fuel tank, and the fuel tank may waste gasoline due to the discharge pressure. [0003] Therefore, there is an urgent need for a system, method and device for reminding the amount of refueling in a fuel tank, which can solve the problem of fuel leakage or deformation of the fuel tank...
