[0002] With the development of the automobile industry, in order to improve the utilization of in-vehicle space, the design of fuel tanks tends to be diversified and irregular. Under complex road conditions, vehicles often stop on steep slopes. The current fuel measurement system mostly uses common technologies such as float and capacitor. They can measure the fuel amount more accurately when the vehicle is in a horizontal state, but in a steep slope environment, these measurement methods are easily affected by the change in fuel distribution caused by the tilt of the fuel tank, and cannot accurately reflect the actual fuel amount. If the difference reaches a certain value, it will trigger the refueling or draining mode, and the fuel gauge will be updated, but the user has not refueled or drained the fuel, which is easy to cause users to distrust the vehicle fuel system and bring a bad user experience.

[0013] Further, in S2, the fuel measurement sensor collects the first fuel sampling value and then collects the second fuel sampling value after a first time interval.

[0014] Furthermore, the control module in S4 determines whether the vehicle is on a steep slope section by, specifically, the angle sensor detects the angle change of the vehicle relative to the horizontal plane and transmits the information of the detected angle change of the vehicle relative to the horizontal plane to the control module, and the control module determines whether the angle change of the vehicle relative to the horizontal plane is greater than a first threshold value. If greater, the control module determines that the vehicle is on a steep slope section.

[0030] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0031] Figure 1 The present invention is a flow chart of a vehicle fuel display control method, the method comprising the following steps:

[0032] S1: User parks the car.

[0033] S2: The fuel measurement sensor 1 collects the first fuel sampling value and the second fuel sampling value. Specifically, after the user stops the vehicle, the fuel measurement sensor 1 collects the first fuel sampling value and then collects the second fuel sampling value after a first time interval, and sends the collected first fuel sampling value and the second fuel sampling value to the control module 2.

[0034] Among them, the first time interval is 15 seconds.

[0035] S3: The control module 2 determines whether the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is less than the first preset value. If not, the process proceeds to S4. Specifically, after the control module 2 receives the first fuel sampling value and the second fuel sampling value, the control module 2 determines whether the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is less than the first preset value. If the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is not less than the first preset value, the process proceeds to S4. If the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is less than the first preset value, the process ends.

[0036] The first preset value is 10% of the total capacity of the fuel tank.

[0037] S4: The control module 2 determines whether the vehicle is on a steep slope section, and if not, enters S5. Specifically, after the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is not less than the first preset value, the control module 2 will determine whether the vehicle is on a steep slope section. The control module 2 determines whether the vehicle is on a steep slope section specifically as follows: the angle sensor 3 detects the angle change of the vehicle relative to the horizontal plane and transmits the information of the detected angle change of the vehicle relative to the horizontal plane to the control module 2. The control module 2 determines whether the angle change of the vehicle relative to the horizontal plane is greater than the first threshold value. If not, the control module 2 determines that the vehicle is not on a steep slope section, and enters S5. If it is greater, it ends.

[0038] Among them, the first threshold is 25°.

[0039] S5: The vehicle triggers the refueling or draining mode, and the fuel gauge is updated. Specifically, when the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is not less than the first preset value, and the control module 2 determines that the angle change of the vehicle relative to the horizontal plane is not greater than the first threshold value, that is, the control module 2 determines that the vehicle is not on a steep slope, then the vehicle triggers the refueling or draining mode, and the fuel gauge is updated. That is, the fuel display control method system of the present invention can avoid inaccurate fuel display when the vehicle is parked on a steep slope, and can also avoid erroneous updates of the fuel gauge when the vehicle is parked on a steep slope, thereby providing users with a better vehicle experience. In addition, the present invention also has the advantage of saving costs.

[0040] Figure 2It is a logical structure diagram of a system of a fuel display control method applicable to a vehicle of the present invention, comprising a fuel measurement sensor 1, a control module 2 and an angle sensor 3. Among them, the output end of the fuel measurement sensor 1 is connected to the input end of the control module 2; the output end of the angle sensor 3 is connected to the input end of the control module 2. In addition, in this specific embodiment, the fuel measurement sensor 3 adopts a float type fuel measurement sensor; the control module 2 adopts a microcontroller (MCU) of a vehicle instrument.

[0041] Combine the following Figure 1 and Figure 2 The working principle of the present invention is introduced as follows:

[0042] After the user stops the vehicle, the fuel measurement sensor 1 collects the first fuel sampling value and then collects the second fuel sampling value after the first time interval, and sends the collected first fuel sampling value and the second fuel sampling value to the control module 2; specifically, after the user stops the vehicle, the fuel tank collects the first fuel sampling value through the float type fuel measurement sensor, and after the first time interval, the fuel tank collects the second fuel sampling value through the float type fuel measurement sensor. The float of the float type fuel measurement sensor floats up and down with the rise and fall of the fuel liquid level, and is connected to a variable resistor through a metal connecting rod. When the fuel liquid level changes, the float moves, thereby changing the position of the metal connecting rod, and then changing the resistance value of the variable resistor. The detection circuit indirectly calculates the current remaining fuel in the fuel tank by measuring the resistance change of the variable resistor and sends it to the control module 2. The control module 2 determines whether the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is less than the first preset value. If the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is not less than the first preset value, the control module 2 will determine whether the vehicle is on a steep slope. The control module 2 determines whether the vehicle is on a steep slope section. Specifically, the angle sensor 3 detects the angle change of the vehicle relative to the horizontal plane and transmits the information of the detected angle change of the vehicle relative to the horizontal plane to the control module 2. The control module 2 determines whether the angle change of the vehicle relative to the horizontal plane is greater than the first threshold. If not, the control module 2 determines that the vehicle is not on a steep slope section, and the vehicle triggers the refueling or draining mode, and the fuel gauge is updated. That is, the fuel display control method system of the present invention can avoid inaccurate fuel display when the vehicle is parked on a steep slope section, and can also avoid the fuel gauge from being updated incorrectly when the vehicle is parked on a steep slope section, thereby providing users with a better car experience. In addition, the present invention also has the advantage of saving costs.

[0043] In addition, the present invention also mentions a vehicle, which is equipped with the aforementioned system and is controlled by the aforementioned vehicle fuel display control method.

The float of the float type fuel measurement sensor floats up and down with the rise and fall of the fuel liquid level, and is connected to a variable resistor through a metal connecting rod. When the fuel liquid level changes, the float moves, thereby changing the position of the metal connecting rod, and then changing the resistance value of the variable resistor. The detection circuit indirectly calculates the current remaining fuel in the fuel tank by measuring the resistance change of the variable resistor and sends it to the control module 2. The control module 2 determines whether the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is less than the first preset value. If the control module 2 determines that the absolute value of the difference between the first fuel sampling value and the second fuel sampling value is not less than the first preset value, the control module 2 will determine whether the vehicle is on a steep slope. The control module 2 determines whether the vehicle is on a steep slope section. Specifically, the angle sensor 3 detects the angle change of the vehicle relative to the horizontal plane and transmits the information of the detected angle change of the vehicle relative to the horizontal plane to the control module 2. The control module 2 determines whether the angle change of the vehicle relative to the horizontal plane is greater than the first threshold. If not, the control module 2 determines that the vehicle is not on a steep slope section, and the vehicle triggers the refueling or draining mode, and the fuel gauge is updated.
