Description
Technical Field
The present invention relates to the field of motor vehicles, and more particularly to a fuel measuring system, a fuel pump and a fuel tank with such a fuel measuring system, a method for calculating a fuel volume using the fuel measuring system, and a storage medium for carrying out the method.
Background
The traditional resistance float rod type height liquid level sensor consists of a slide rheostat arranged on an oil pump, a float arranged outside the oil pump and a metal float rod connecting the float and the slide rheostat. The float floats on the fuel liquid level, when the liquid level changes, the float enables the float rod to rotate around the shaft, the contact point of the slide rheostat connected with the float rod moves synchronously, and therefore resistance value changes. The traditional resistance value float rod height liquid level sensor has the following defects: the float rod is relatively slender, and therefore there is a risk of deformation during transportation, installation and later use, resulting in inaccurate oil levels. And when arranging the oil tank with a special shape, the problem of difficult or impossible arrangement exists. In addition, the float can interfere with the oil tank, so that the float rod is stressed and deformed, and the problem of inaccurate resistance value is caused.
The resistance value sensor consists of a resistance value sheet and a sliding contact, wherein the resistance value sheet and the sliding contact move relatively in use, and the surfaces of the resistance value sheet and the sliding contact rub with each other, so that the problems of abrasion, corrosion and the like exist after long-term use, and the resistance value output is inaccurate. The precision of the resistance value sensor is determined by the size of the resistance value sheet, if the precision is improved, the resistance value of a single resistance value sheet is required to be as small as possible, so that the total number of the resistance value sheets is increased, and the problem of high cost exists.

According to an embodiment of the invention, the fuel measuring system comprises a first pressure sensor and a second pressure sensor for measuring fuel pressures at different heights, respectively, and a third pressure sensor arranged at the bottom for measuring the fuel pressure at the bottom. The fuel level height is obtained by calculating the measured values of the three pressure sensors, and the measured values are converted into the volume value of the fuel left in the fuel tank. For example, the fuel volume value may be output to a driver fuel gauge indication system.
The first pressure sensor and the second pressure sensor may be disposed inside an oil pump, for example, the first pressure sensor and the second pressure sensor may be disposed inside a storage barrel of the oil pump. No matter the level of the fuel in the fuel tank, the interior of the oil storage barrel of the fuel pump is generally filled with the fuel, so that the first pressure sensor and the second pressure sensor which are arranged inside the oil storage barrel of the fuel pump can always detect the pressure of the fuel.

The height difference of the pressure detection ports of the oil pump top pressure sensor 5 and the oil pump bottom pressure sensor 6 is a density calibration height 8, and the density calibration height 8 is a predetermined value.
According to a pressure calculation formula p = ρ gh, the fuel density is obtained by dividing the pressure difference of the two pressure sensors by the product of the gravity constant and the height 8. In the case of the fuel level 3 shown in the figure, the pressure sensor 7 arranged at the bottom of the outer surface of the reservoir of the oil pump can measure the pressure value of the whole fuel in the tank, and the fuel level 9 in the tank is obtained by dividing this value by the product of the gravity constant and the fuel density according to the pressure calculation formula p = ρ gh. And matching the liquid level height 9 in the oil tank with a liquid level height and volume corresponding relation table generated during the development of the oil tank to finally obtain the volume value of the residual fuel oil in the oil tank.
