[0002] As automotive technology advances and people's demands for vehicle performance increase, automakers are constantly launching smarter and more efficient models to meet market needs. Nevertheless, some fundamental components remain indispensable to modern cars, such as the fuel pump. For non-electric vehicles, the fuel pump is a crucial component.

[0003] A fuel pump typically consists of two main parts: a fuel supply assembly and a sensor assembly. The fuel supply assembly is responsible for providing the engine with the necessary pressure and flow of fuel to ensure that the engine can start and run properly; the sensor assembly is used to monitor the fuel level in the fuel tank in real time and convert this information into visual data displayed on the dashboard to help the driver understand the amount of fuel remaining in the vehicle.

[0004] However, due to the different designs of each vehicle model, the resistance range and key resistance values ​​of its sensor components will also vary, resulting in a lot of repetitive development work. At the same time, the detection circuit and conversion algorithm of the fuel gauge need to be redesigned for each new vehicle model, which increases the workload and complexity.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0027] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] In related technologies, for a certain vehicle model, the sensor component design is generally as shown in Table 1, where Table 1 is the sensor resistance value table for vehicle model one.

[0029] Table 1

[0030]

[0031]

[0032] When a new model needs to be developed, the newly designed sensor components may be modified to the values ​​shown in Table 2, depending on the amount of fuel in the fuel tank. Table 2 is a table of sensor resistance values ​​for model two.

[0033] Table 2

[0034]

[0035] Consequently, the sensor components in this technology are redesigned for each vehicle model, with varying resistance ranges and key resistance points, leading to a significant amount of repetitive development work. Furthermore, these parameters also need to be output to the fuel gauge, requiring engineers to redesign the fuel gauge's resistance detection circuitry, conversion algorithms, and so on, each time based on these different parameters.

[0036] To address this issue, this application proposes a method for designing the resistance value of an automotive fuel pump sensor. This method can solve the problem of different sensor resistance ranges and key point resistance settings for different vehicle models, and unify the sensor resistance value design for all vehicle models. This method will be described in detail below.

[0037] The following description, with reference to the accompanying drawings, outlines a fuel pump sensor resistance design method, apparatus, sensor, vehicle, and medium according to embodiments of this application. Addressing the issue mentioned in the background art where different vehicle models have varying resistance ranges and key resistance values ​​for sensor components, necessitating the redesign of the fuel gauge's detection circuit and conversion algorithm, thus increasing workload and complexity, this application provides a fuel pump sensor resistance design method. In this method, the target design quantity and requirements for fuel pump sensors are determined based on the vehicle type, and a sensor resistance detection circuit is designed. These three elements work together to generate a resistance table for the target vehicle's fuel pump sensors. This solves the problem of inconsistent sensor resistance ranges and key resistance value settings across different vehicle models, unifying sensor resistance design for all models and significantly reducing repetitive design work. Therefore, it resolves the issue of different resistance ranges and key resistance values ​​for sensor components across different vehicle models, eliminating the need to redesign the fuel gauge's detection circuit and conversion algorithm, which increases workload and complexity.

[0038] Specifically, Figure 1 This is a flowchart illustrating a method for designing the resistance value of a fuel pump sensor, as provided in an embodiment of this application.

[0039] like Figure 1 As shown, the method for designing the resistance value of the fuel pump sensor includes the following steps:

[0040] In step S101, the vehicle type of the target vehicle is identified.

[0041] The identification can be achieved through manual input, sensor recognition, or other methods; vehicle types include sedans or small cars, SUVs or trucks, and high-performance vehicles.

[0042] It is understandable that different vehicle types will result in different fuel tank levels, which in turn will lead to differences in sensor components. In this application embodiment, the vehicle type of the target vehicle can be identified through manual input, sensor recognition, or other methods.

[0043] In step S102, the target design quantity and target design requirements of fuel pump sensors are determined according to the vehicle type.

[0044] Understandably, the target number of fuel pump sensors needs to be determined based on the vehicle type. For example, sedans or small cars typically have only one fuel tank and only need one fuel pump sensor; SUVs or trucks may have larger fuel tanks or dual fuel tank designs and require more sensors; high-performance vehicles may use multiple fuel pumps to ensure a stable fuel supply, and therefore may require more sensors; target design requirements include resistance range, etc.

[0045] In step S103, a resistance table of the fuel pump sensor for the target vehicle is generated based on the target design quantity, target design requirements, and sensor resistance detection circuit.

[0046] The sensor resistance detection circuit is designed based on relevant data from fuel pump sensors for multiple vehicle types. This data includes the number of sensors in the fuel tank, sensor current data, and resistance data, among other things.

[0047] It is understood that, after determining the target design quantity and target design requirements of the fuel pump sensors in the embodiments of this application, the sensor resistance detection circuit is designed based on data such as the number of fuel pump sensors of the vehicle type and the sensor resistance range, and a resistance table of the fuel pump sensors of the target vehicle is generated according to the target design quantity, target design requirements and sensor resistance detection circuit.

[0048] In this embodiment of the application, generating a resistance table for the fuel pump sensor of the target vehicle based on the target design quantity, target design requirements, and sensor resistance detection circuit includes: if the target design quantity is one, identifying the target design requirements to determine the fixed resistance value corresponding to the unit volume, and determining the sensor resistance range based on the sensor resistance detection circuit; and designing a resistance table for the fuel pump sensor of the target vehicle based on the fixed resistance value corresponding to the unit volume and the sensor resistance range.

[0049] It is understood that, after determining the target design quantity and target design requirements of the fuel pump sensor and designing the sensor resistance detection circuit, if the target design quantity is one, the fixed resistance value corresponding to the unit volume is determined according to the target design requirements using the method of fixed resistance value corresponding to unit volume. Finally, the resistance value table of the fuel pump sensor of the target vehicle is designed according to the fixed resistance value corresponding to the unit volume and the sensor resistance value range.

[0050] For example, if we set 3Ω for every 1L of fuel and the sensor resistance range is 80Ω to 380Ω, we can set the fuel pump sensor resistance to 380Ω when the tank is empty, and decrease it by 3Ω for every additional liter of fuel. When the tank is full, the fuel pump sensor resistance will be 80Ω. We can set some key resistance points during the resistance change process. For example, when there are only 15L of fuel left, the fuel pump sensor resistance is 335Ω, which can be set as an alarm point to generate a resistance table for the fuel pump sensor of the target vehicle.

[0051] In this embodiment, generating a resistance table for the fuel pump sensor of the target vehicle based on the target design quantity, target design requirements, and sensor resistance detection circuit includes: if the target design quantity is two, identifying the target design requirements to determine the fixed resistance value corresponding to the unit volume, and determining the total sensor resistance range based on the sensor resistance detection circuit; determining the respective resistance range of the two sensors based on the fuel quantity ratio of the main and auxiliary chambers of the fuel tank, the fuel quantity ratio, and the total sensor resistance range; and designing the resistance table for the fuel pump sensor of the target vehicle based on the fixed resistance value corresponding to the unit volume and the respective resistance range of the two sensors.

[0052] Understandably, if the target design quantity is two, then according to the target design requirements, the fixed resistance value corresponding to the unit volume is determined by using the method of fixed resistance value corresponding to the unit volume. Then, the fuel quantity ratio of the main and auxiliary chambers of the fuel tank is obtained. Based on the fuel quantity ratio and the total sensor resistance value range, the resistance value range of each of the two sensors is determined. Finally, the resistance value table of the fuel pump sensor of the target vehicle is designed based on the fixed resistance value corresponding to the unit volume and the sensor resistance value range.

[0053] For example, setting 3Ω for every 1L of fuel, with a fuel volume ratio of 4:1 between the main and auxiliary chambers of the fuel tank, and a total sensor resistance range of 80Ω to 380Ω (meaning the combined resistance of the two sensors is 80Ω to 380Ω), and allocating the resistance proportionally, we can obtain a resistance range of 40Ω to 280Ω for the main chamber sensor 1 and 40Ω to 100Ω for the auxiliary chamber sensor 2. Then, when the tank is empty, the fuel pump sensor resistance can be set to 380Ω, sensor 1 to 280Ω, and sensor 2 to 100Ω. For every additional liter of fuel, the total fuel pump sensor resistance decreases by 3Ω. When the tank is full, the fuel pump sensor resistance is 80Ω, sensor 1 to 40Ω, and sensor 2 to 40Ω. During these resistance changes, key resistance points can be set. For example, when only 15L of fuel remains in the tank, the total fuel pump sensor resistance is 335Ω, which can be set as an alarm point, thus generating a resistance table for the target vehicle's fuel pump sensors.

[0054] In this embodiment, before generating the resistance table of the fuel pump sensor for the target vehicle based on the target design quantity, target design requirements, and sensor resistance detection circuit, the process includes: identifying current data and resistance data from relevant data of fuel pump sensors for multiple vehicle types; designing the rated current range of the sensor resistance detection circuit based on the current data, and designing the rated resistance range of the sensor resistance detection circuit based on the resistance data and the number of sensors; calculating the protection resistor value of the sensor resistance detection circuit based on the rated current range and the rated current range corresponding to different numbers of sensors; and designing the sensor resistance detection circuit based on the protection resistor value, the rated resistance range, and the rated current range corresponding to different numbers of sensors.

[0055] The rated current range of the sensor resistance detection circuit is the current range that meets the normal operation of the sensor. Exceeding the rated current range can easily cause sensor burnout, while falling below the rated current range will result in a decrease in detection accuracy. The protection resistor of the detection circuit is used to protect the circuit from burnout. The resistance value of the protection resistor is calculated based on the rated current range and the rated current range corresponding to different numbers of sensors.

[0056] It is understood that, before generating the resistance table of the fuel pump sensor for the target vehicle based on the target design quantity, target design requirements, and sensor resistance detection circuit, this application embodiment needs to calculate the rated current range, rated resistance range, and protection resistor value of the sensor resistance detection circuit based on the vehicle type and relevant data of its fuel pump sensor. The sensor resistance detection circuit is designed based on these three factors to ensure that the sensor resistance detection circuit can operate safely and normally.

[0057] In this embodiment of the application, after generating the resistance table of the fuel pump sensor of the target vehicle according to the target design quantity, target design requirements and sensor resistance detection circuit, the method further includes: generating a software update package for the fuel gauge of the target vehicle according to the resistance table; and updating the resistance band of the fuel gauge of the target vehicle according to the software update package.

[0058] Among them, software updates can be achieved through OTA (Over-the-Air) technology; the resistance band is a resistance band that no longer distinguishes between general resistance bands and critical resistance bands. Using this type of resistance band, you only need to input the new resistance value into the instrument, and the fuel gauge software can be updated to adjust the instrument.

[0059] It is understood that, by applying a resistance band of a newly designed sensor component, the software update package for the target vehicle's fuel gauge, generated based on the resistance table, can be updated to the vehicle via OTA. This is fast and convenient, and the fuel gauge can be easily adjusted without changing the sensor, greatly improving efficiency and saving costs.

[0060] According to the fuel pump sensor resistance design method proposed in this application, the target design quantity and target design requirements of fuel pump sensors can be determined based on the vehicle type of the target vehicle, and a sensor resistance detection circuit can be designed. By jointly generating the resistance table of fuel pump sensors for the target vehicle, the problem of different sensor resistance ranges and key point resistance settings for different vehicle models can be solved, and the sensor resistance design of all vehicle models can be unified, greatly reducing repetitive design work.

[0061] The following is a specific embodiment to further describe the fuel pump sensor resistance design method proposed in this application.

[0062] First, a general-purpose resistance detection circuit needs to be designed. Based on current practical considerations in sensor component design, the design of the resistance detection circuit will be described step-by-step below.

[0063] (1) The rated current I of the sensor is generally around (10~50) mA. If it is too large, it will easily cause the sensor to burn out. If it is too small, the detection accuracy will decrease.

[0064] Here, I = (20~40) mA is taken as the rated current range of the sensor.

[0065] (2) The resistance range R of a single sensor component is generally (20~400)Ω. If the range is too large, the resistance jump between the two resistance bands will be too large. If the range is too small, the process difficulty will be increased due to the dense resistance bands.

[0066] We need to consider two scenarios here:

[0067] The first scenario: There is only one sensor in the fuel tank. The given sensor resistance range is Rx = (80~380)Ω, the initial resistance of the sensor is R0 = 80Ω, and the final resistance is Rf = 380Ω.

[0068] The second scenario: There are two sensors in the fuel tank. Given Rx = Rx1 + Rx2 = (80 ~ 380) Ω, each sensor has the same initial resistance, R01 = 40 Ω, R02 = 40 Ω, and the final resistance is Rf = Rf1 + Rf2 = 380 Ω.

[0069] (3) The voltage U of the detection circuit is generally the voltage of the vehicle battery. After voltage regulation, the voltage can be stabilized at 12V.

[0070] (4) The basic schematic diagram of the sensor resistance detection circuit is shown below. Figure 2 , Figure 3 As shown, Figure 2 This is a basic circuit diagram for single-sensor resistance detection. Figure 3 This is a basic circuit diagram for resistance detection using two sensors. In these two circuits, U = 12V and I = (20~40)mA.

[0071] exist Figure 2 In the circuit, R = Rd + Rx = U / I.

[0072] exist Figure 3 In the circuit, R = Rd + (Rx1 + Rx2) = U / I.

[0073] Based on the information provided in (1), (2), and (3), we can calculate R = Rd + Rx = U / I = (300 ~ 600)Ω.

[0074] (5) Substituting Rx, we get Rd = 220Ω, which is the resistance value of the protection resistor of the detection circuit. This gives us a fixed sensor resistance detection circuit.

[0075] Next, we will design the sensor resistance value for a 100L fuel tank, based on two scenarios according to the target design quantity in the fuel tank.

[0076] The first scenario: There is only one sensor in the fuel tank.

[0077] (1) Sensor resistance range Rx = (80~380)Ω.

[0078] (2) In order to obtain the most accurate display accuracy, a fixed resistance value is adopted for each unit volume. 3Ω is set for each 1L of fuel. Assuming that a 100L fuel tank can travel 1000km, the sensor resistance value table shown in Table 3 can be obtained. Table 3 is the resistance value table of a single sensor.

[0079] Table 3

[0080]

[0081] The second scenario: There are two sensors in the fuel tank.

[0082] (1) According to the designed detection circuit, the sensor resistance range is still Rx=(Rx1+Rx2)=(80~380)Ω.

[0083] (2) The use of two sensors is generally applied to saddle-shaped fuel tanks to measure the fuel quantity in each of the two chambers separately. For example... Figure 4 The diagram shown is a schematic of a saddle-shaped fuel tank. For ease of calculation, it is assumed that the fuel volume of the main chamber is V1 / V2 = 4:1, that is, V1 = 80L for the main chamber and V2 = 20L for the auxiliary chamber.

[0084] (3) In order to obtain the most accurate display accuracy, a fixed resistance value is adopted per unit volume, and 3Ω is set for each 1L of fuel. The resistance ranges of Rx1 and Rx2 are allocated as follows.

[0085] ΔRx1 / V1=ΔRx2 / V2

[0086] (4) Substituting V1 and V2, we get ΔRx1 = 240Ω and ΔRx2 = 60Ω. Therefore, the resistance range of the two sensors is Rx1 = (40~280)Ω and Rx2 = (40~100)Ω. Assuming that a 100L fuel tank can travel 1000km, we can obtain the sensor resistance table as shown in Table 4, where Table 4 is the resistance table of the two sensors.

[0087] Table 4

[0088]

[0089] After obtaining the sensor resistance value table, it is necessary to make certain improvements to the resistance value range of existing sensor components. Currently commonly used sensor component resistance value ranges, such as... Figure 5 As shown. This resistance value band distinguishes between general resistance value bands and critical resistance value bands, resulting in poor design versatility. For example, Figure 5 The instrument corresponds to 90% of the rated volume. If it is to be adjusted to correspond to 85% of the rated volume, the resistance band must be redesigned and the key resistance band moved to 85%. This adjustment requires mold adjustment, which is expensive and time-consuming.

[0090] The resistance band of the newly designed sensor assembly is as follows: Figure 6 As shown. The distinction between general resistance bands and critical resistance bands is no longer made; this resistance band design scheme offers good versatility. As described above... Figure 5 For example, Figure 5 The instrument panel corresponds to 90% of the rated volume. If you want to adjust the instrument panel to correspond to 85% of the rated volume, you only need to input the new resistance value into the instrument panel and update the fuel gauge software. This can be achieved through OTA upgrades, which are inexpensive and quick.

[0091] This embodiment designs a universal sensor resistance detection circuit, eliminating the need for separate design based on vehicle model. For the case of a single sensor in the fuel tank, the total sensor resistance meter is universal, and the same total resistance meter is input to both the fuel gauge and fuel pump manufacturers. Similarly, for the case of two sensors in the fuel tank, the total sensor resistance meter is also universal, and the same total resistance meter is input to both the fuel gauge and fuel pump manufacturers. This solves the problem of different sensor components and key resistance points in different vehicle models requiring redesigned fuel gauge detection circuits and conversion algorithms, thus increasing workload and complexity.

[0092] Next, referring to the accompanying drawings, a fuel pump sensor resistance design device according to an embodiment of this application is described.

[0093] Figure 7 This is a block diagram of a fuel pump sensor resistance design device according to an embodiment of this application.

[0094] like Figure 7 As shown, the fuel pump sensor resistance design device 10 includes: an identification module 201, a determination module 202, and a design module 203.

[0095] The identification module 201 is used to identify the vehicle type of the target vehicle; the determination module 202 is used to determine the target design quantity and target design requirements of the fuel pump sensor according to the vehicle type; and the design module 203 is used to generate a resistance table of the fuel pump sensor of the target vehicle according to the target design quantity, target design requirements and sensor resistance detection circuit, wherein the sensor resistance detection circuit is designed based on the relevant data of fuel pump sensors of multiple vehicle types.

[0096] In this embodiment, the design module 203 is further configured to: if the target design quantity is one, identify the target design requirements to determine the fixed resistance value corresponding to the unit volume, and determine the sensor resistance value range according to the sensor resistance detection circuit; and design the resistance value table of the fuel pump sensor of the target vehicle according to the fixed resistance value corresponding to the unit volume and the sensor resistance value range.

[0097] In this embodiment, the design module 203 is further configured to: if the target design quantity is two, identify the target design requirements to determine the fixed resistance value corresponding to the unit volume, and determine the total sensor resistance range according to the sensor resistance detection circuit; determine the respective resistance range of the two sensors according to the fuel quantity ratio of the main and auxiliary chambers of the fuel tank, the fuel quantity ratio and the total sensor resistance range; and design a resistance table for the fuel pump sensor of the target vehicle according to the fixed resistance value corresponding to the unit volume and the respective resistance range of the two sensors.

[0098] In this embodiment, the design module 203 is further configured to: identify current data and resistance data in the relevant data of fuel pump sensors for multiple vehicle types; design the rated current range of the sensor resistance detection circuit based on the current data, and design the rated resistance range of the sensor resistance detection circuit based on the resistance data and the number of sensors; calculate the resistance value of the protection resistor of the sensor resistance detection circuit based on the rated current range and the rated current range corresponding to different numbers of sensors; and design the sensor resistance detection circuit based on the protection resistor value, the rated resistance range, and the rated current range corresponding to different numbers of sensors.

[0099] In this embodiment of the application, after generating the resistance table of the fuel pump sensor of the target vehicle according to the target design quantity, target design requirements and sensor resistance detection circuit, the method further includes: generating a software update package for the fuel gauge of the target vehicle according to the resistance table; and updating the resistance band of the fuel gauge of the target vehicle according to the software update package.

[0100] It should be noted that the foregoing explanation of the fuel pump sensor resistance design method embodiment also applies to the fuel pump sensor resistance design device of this embodiment, and will not be repeated here.

[0101] According to the fuel pump sensor resistance design device proposed in this application, by using an identification module, a determination module, and a design module, the target design quantity and target design requirements of fuel pump sensors can be determined according to the vehicle type of the target vehicle, and a sensor resistance detection circuit can be designed.
