A method for measuring the fuel volume of a vehicle fuel tank

Abstract

The invention discloses a method for measuring the oil quantity of a vehicle fuel tank. The main components include a fuel quantity sensor, a vehicle-mounted terminal, an engine controller and wires; firstly, the parameters of the fuel tank are calibrated; The calibrated fuel volume calibration value corresponding to the corresponding gear position; then carry out the fuel volume measurement between the two gears; when the fuel temperature changes, the calibration parameters of the fuel tank are corrected; The temperature change affects the authenticity of the fuel quantity data, the vehicle cost does not change, and the electrical fault points do not increase.

Description

technical field [0001] The invention belongs to the field of vehicle fuel tanks, and in particular relates to a method for measuring the fuel volume of a vehicle fuel tank. Background technique [0002] Since the driver of a commercial vehicle is not the same person as the owner of the vehicle, there is often a situation where the actual fuel consumption does not match the bill when the driver reimburses the owner for a fuel ticket. To solve this problem, the traditional technical solution is to install a high-precision fuel quantity sensor inside the fuel tank, and use the vehicle-mounted terminal to record the change process of the liquid level of the fuel tank. Disadvantages of prior art: [0003] 1. It is necessary to add additional work such as fuel tank openings and cables, which is a heavy workload and has potential safety hazards; [0004] 2. The high-precision oil quantity sensor is expensive, which increases the cost of the whole vehicle; [0005] 3. In the case...

Problems solved by technology

[0003] 1. It is necessary to add additional work such as fuel tank openings and cables, which is a heavy workload and has potential safety hazards;

[0004] 2. The high-precision oil quantity sensor is expensive, which increases the cost of the whole vehicle;

[0005] 3. In the case of a large-volume fuel tank, the oil volume changes too much between the two scales, and accurate monitoring cannot be realized;
