Problems solved by technology

However, due to the combination of the sliding potentiometer and the lever, it is difficult to achieve high indication accuracy requirements
There are two main reasons. First, the shape of the fuel tank is not a standardized geometric shape, and it is impossible to establish an accurate correspondence between the indication on the meter head and the amount of fuel.
; Two, the mechanical error of the sliding resistor and the float lever mechanism is relatively large, and the accuracy of the magnetic meter head (or electromagnetic meter head) is not high

Embodiment Construction

[0039] In the embodiment shown in Fig. 1, two sensors are used to place on the center line of the cuboid fuel tank, and the computer system can be used to measure the longitudinal slope of the vehicle location, and the oil in the fuel tank can be measured when the lateral slope is not large. how much.

[0040] Figure 2 and image 3 In the shown embodiment, three sensors are used to be placed in the cuboid fuel tank (three sensors are not on the same straight line), and the computer system can be used to measure the longitudinal slope and the lateral slope of the vehicle site under any slope situation, and can be used in any Measure the amount of fuel in the fuel tank under slope conditions, combined with computer technology, it can easily measure the amount of fuel added each time and the fuel consumption per 100 kilometers.

Abstract

The invention provides an automotive fuel tank system of road grade measuring data and fuel bulk measuring data, which is characterized by the following: detecting the oil tank position corresponding to the fuel oil level due to more than two oil level sensors (three oil level sensors on common); providing the inclined condition data of fuel oil tank and fuel oil quantity data to the microcomputer system under the different heights of oil level senor condition; indicating the road inclination through the microcomputer system (strictly speaking, indicating the fuel oil inclination) to display the fuel oil quantity; measuring the oil consumption per one hundred kilometer through mating utility with the electronic odometer.

Description

Technical field [0001] The invention relates to a motor vehicle fuel tank measuring device, which can accurately indicate the inclination (slope) of the road where the motor vehicle is located by cooperating with a computer system. It can more accurately indicate the fuel reserve in the fuel tank, and can more accurately display data such as the amount of fuel refueled and the fuel consumption per 100 kilometers. Background technique [0002] At present, there is no motor vehicle installed to indicate the road slope meter. [0003] At present, the common motor vehicle fuel tank fuel quantity indicator is formed by connecting a sliding resistor (or potentiometer), a float, a lever, an electromagnetic gauge (or a magnetoelectric gauge) with a wire. When fuel is injected into the fuel tank, the float floats from the bottom of the fuel tank on the upper surface of the fuel, and the lever drives the sliding contact of the resistor to change the resistance value of the connected ...
