[0002] Oil leaks often occur during vehicle operation. If not dealt with in time, they can compromise driving safety and cause significant economic losses.

[0003] Currently, when a vehicle's fuel tank leaks, besides the controller alerting the user, timely action relies primarily on the individual's sense of smell and sight. Furthermore, vehicle fuel tank system inspections typically only detect leaks, failing to quantify the severity of the damage and leakage. Summary of the Invention

[0004] This application provides a method, apparatus, device, and storage medium for determining the extent of vehicle oil leakage, to at least solve the problem in related technologies that cannot detect the extent of damage to a vehicle's fuel tank.

[0012] Based on the aforementioned technical means, this application can mathematically calculate the theoretical oil leakage amount of each preset damaged area among multiple preset damaged areas of the vehicle's fuel tank within a preset time period.

[0013] In one possible implementation, the multiple theoretical oil leakage amounts include a first theoretical oil leakage amount and a second theoretical oil leakage amount, wherein the first theoretical oil leakage amount is less than the second theoretical oil leakage amount. The aforementioned "determining the degree of damage to the vehicle's fuel tank based on the actual oil leakage amount and the multiple theoretical oil leakage amounts" includes: if the actual oil leakage amount is less than or equal to the first theoretical oil leakage amount, then the degree of damage to the vehicle's fuel tank is determined to be minor damage; if the actual oil leakage amount is greater than the first theoretical oil leakage amount but less than or equal to the second theoretical oil leakage amount, then the degree of damage to the vehicle's fuel tank is determined to be moderate damage; if the actual oil leakage amount is greater than the second theoretical oil leakage amount, then the degree of damage to the vehicle's fuel tank is determined to be severe damage.

[0014] Based on the aforementioned technical means, this application can compare the actual oil leakage amount with the theoretical oil leakage amount to identify the degree of damage to the vehicle's fuel tank.

[0034] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] For ease of understanding, the method for determining the degree of vehicle oil leakage provided in this application will be described in detail below with reference to the accompanying drawings.

[0037] As mentioned in the background technology, in the event of a fuel tank leak, this application provides a method for determining the extent of fuel tank damage to allow users to clearly see the degree of damage. This method uses the instantaneous fuel consumption and remaining fuel level obtained by the vehicle control module to determine the actual fuel tank leakage within a preset time period. Based on the internal pressure and fuel level of the fuel tank, the theoretical leakage amount for each of the multiple preset damage areas within the preset time period is determined. The vehicle control unit then compares the actual and theoretical leakage amounts and outputs the degree of fuel tank damage via voice announcement and large-screen display, reminding the user to check the tank, thus ensuring user safety. Compared to existing technologies, the method proposed in this application not only identifies fuel tank damage but also the degree of damage, thereby detecting the extent of fuel tank leakage. Furthermore, this method requires less data to calculate the degree of fuel tank leakage, is simpler to calculate, and does not require additional components to determine the extent of fuel tank damage, reducing operating costs.

[0038] like Figure 1 The diagram shown is a structural schematic of a system for determining the degree of oil leakage in a vehicle, provided in an embodiment of this application. It includes a vehicle control unit (VCU), an electronic control unit (ECU), an engine management system (EMS), a display module, and a voice broadcast module.

[0039] The vehicle control module is used to calculate the actual amount of oil leakage and output information indicating the degree of damage to the vehicle's fuel tank.

[0040] The electronic control module is used to calculate the instantaneous fuel consumption of the vehicle during driving, and also to send a fuel leak signal to the vehicle control module.

[0041] The engine management system is used to store vehicle fuel tank sensor data and send it to the vehicle control module.

[0042] The display module and voice broadcast module are used to receive signals sent by the vehicle control module and output the degree of damage to the vehicle's fuel tank to the user.

[0043] Figure 2 This is a flowchart illustrating a method for determining the degree of vehicle oil leakage according to an exemplary embodiment, such as... Figure 2 As shown, the method for determining the extent of oil leakage in this vehicle includes the following steps:

[0044] S201. Acquire data from the vehicle's fuel tank sensor when the vehicle is leaking oil.

[0045] The vehicle fuel tank sensor data includes the remaining fuel level, instantaneous fuel consumption during vehicle operation, internal fuel tank pressure, and fuel level in the tank.

[0046] The remaining fuel level and fuel level in the tank are measured using a fuel level sensor. Instantaneous fuel consumption during vehicle operation is calculated by the vehicle control module. The internal pressure of the fuel tank is measured using a fuel tank pressure sensor.

[0047] In one possible implementation, when the vehicle is powered on normally and the vehicle fuel tank sensor is fault-free, in response to the vehicle control module receiving a fuel tank leak signal from the electronic control unit, the vehicle control module receives the vehicle fuel tank sensor data sent by the electronic control module and the engine management system, and stores the data.

[0048] For example, the data obtained by the vehicle control module at the current moment includes: 20 liters of fuel remaining in the fuel tank, 10 liters of instantaneous fuel consumption per 100 kilometers during vehicle operation, 7 kPa internal pressure in the fuel tank, and 30 centimeters of fuel level in the fuel tank.

[0049] S202. Determine the actual amount of fuel leakage from the vehicle's fuel tank within a preset time period based on the instantaneous fuel consumption and the remaining fuel in the tank during vehicle operation.

[0050] In one possible implementation, based on the fuel tank sensor data obtained in S201 above, if the vehicle is in motion, the amount of fuel consumed by the vehicle during a preset time period can be expressed as Formula 1:

[0051]

[0052] Where 0 to t represents a preset time period, M BSFG This indicates the instantaneous fuel consumption of a vehicle within a preset time period, expressed in M. ENG This indicates the actual fuel consumption of the vehicle within a preset time period.

[0053] During this process, the vehicle consumes fuel in its tank while driving, and the remaining fuel level decreases. The actual amount of fuel leaked from the tank within a preset time period can be expressed as Formula 2:

[0054] ΔM t =MM t -M ENG Formula 2

[0055] Where, ΔM t M represents the actual amount of oil leaking from the fuel tank, and M represents the amount of fuel in the tank at time 0. t This indicates the amount of fuel remaining in the tank at time t.

[0056] In another possible implementation, if the vehicle is stationary, the fuel in the vehicle's fuel tank is not consumed by driving, and the actual amount of fuel leakage from the vehicle's fuel tank during a preset time period can be expressed as Formula 3:

[0057] ΔM t =MM t Formula 3

[0058] In one example, if the fuel tank has 50 liters at time 0 and 30 liters at time t, and the vehicle consumes 10 liters of fuel in a preset time period, then the actual amount of fuel leaked from the vehicle's fuel tank during the preset time period is 10 liters.

[0059] In another example, if the vehicle is stationary and the fuel tank has 50 liters of fuel at time 0 and 30 liters of fuel remaining at time t, then the actual amount of fuel leaked from the vehicle's fuel tank during the preset time period is 20 liters.

[0060] S203. Based on the internal pressure of the vehicle's fuel tank and the fuel level in the tank, determine the theoretical oil leakage amount for each of the multiple preset damaged areas of the vehicle's fuel tank within a preset time period, so as to obtain multiple theoretical oil leakage amounts.

[0061] Each preset damage area is the sum of all damage areas in the same fuel tank. For example, the shape of the fuel tank damage can be a dot shape, a crack shape, etc. Multiple preset damage areas can include a first damage area and a second damage area.

[0062] In one possible implementation, the vehicle control module substitutes the internal pressure data of the fuel tank and the fuel level data obtained in S201 into Formula 4 to obtain the fuel flow rate of the vehicle during the fuel leak process.

[0063]

[0064] Among them, P 外 This indicates the relative pressure of the atmosphere outside the fuel tank; at this point, the relative pressure is 0 kPa. H 外 This indicates the height from the bottom of the fuel tank to the crack in the tank, which is 0. ρ represents the fuel density, in kg / m³. 3 V t This indicates the flow rate of oil leaking from the damaged area of ​​the fuel tank. (P) t H indicates the pressure inside the fuel tank. t V represents the height of the oil level in the tank. V0 represents the rate at which the oil level in the tank drops. Since the cross-sectional area of ​​the tank is very large, the oil level drops very slowly, so the rate of drop can be 0.

[0065] Therefore, the flow rate V of the leaking fuel from the vehicle's fuel tank t This can be expressed as Formula 5:

[0066]

[0067] Furthermore, the vehicle control module calculates the theoretical oil leakage amount of each preset damaged area among multiple preset damaged areas of the vehicle's fuel tank within a preset time period according to Formula 6.

[0068]

[0069] Among them, Q t S represents the theoretical oil leakage amount over a preset time period. x This indicates different preset areas.

[0070] Substituting Formula 5 into Formula 6, we obtain Formula 7:

[0071]

[0072] Solving Equation 7 yields Equation 8:

[0073]

[0074] In one example, the theoretical oil leakage amount under different preset areas within the same preset time period is calculated according to Formula 8 above. For example, the theoretical oil leakage amount corresponding to preset area S1 is Q1, and the theoretical oil leakage amount corresponding to preset area S2 is Q2. When the preset time period is 10 minutes, if S1 = 5 square millimeters, Q1 = 50 milliliters is calculated; if S1 = 10 square millimeters, Q1 = 100 milliliters is calculated, then S1 <S2,Q1<Q2。

[0075] S204. Determine the extent of damage to the vehicle's fuel tank based on the actual amount of oil leakage and multiple theoretical amounts of oil leakage.

[0076] The degree of damage to the fuel tank can be categorized as minor, moderate, or severe. The leak level indicator is used to prompt the user to inspect the tank.

[0077] In one possible implementation, the vehicle control module compares the actual oil leakage calculated in S202 with the theoretical oil leakage calculated in S203, and outputs a warning message indicating the extent of fuel tank damage. For example, the output can be displayed on an in-vehicle screen or announced via voice.

[0078] Specifically, given multiple preset damage areas (first and second preset damage areas), if the actual oil leakage is less than the theoretical leakage corresponding to the first preset area, a minor damage warning message for the fuel tank will be output. For example, the in-vehicle screen may display "Your fuel tank has minor damage, please check," and the user may be reminded via voice announcement.

[0079] If the actual oil leakage is greater than the theoretical leakage amount corresponding to the first preset area but less than the theoretical leakage amount corresponding to the second preset area, a message indicating moderate damage to the fuel tank will be output. For example, the vehicle screen will display "Your fuel tank has moderate damage, please check," and the user will be reminded via voice announcement.

[0080] If the actual oil leakage exceeds the theoretical leakage amount corresponding to the second preset area, a warning message indicating the severity of fuel tank damage will be output. For example, the in-vehicle screen will display "Your fuel tank is severely damaged, please check," and a voice announcement will be made to remind the user.

[0081] based on Figure 2 The method described in this application provides a method for determining the degree of vehicle fuel leakage. This method uses the instantaneous fuel consumption and remaining fuel level in the tank obtained by the vehicle control module to determine the actual fuel leakage within a preset time period. Based on the internal pressure and fuel level in the tank, the theoretical fuel leakage for each of the multiple preset damaged areas within the preset time period is determined. The vehicle control unit then compares the actual and theoretical leakage amounts and outputs the degree of fuel tank damage via voice announcement and large-screen display, reminding the user to check the tank and ensuring user safety. Compared to existing technologies, the method proposed in this application not only identifies fuel tank damage but also determines the degree of damage. Furthermore, this method requires less data to calculate the degree of fuel tank leakage, making the calculation simpler and eliminating the need for additional components, thus reducing operating costs.
