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

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

[0029] Table 1

[0030]

[0031]

[0032] When a new model needs to be developed, the newly designed sensor assembly may be modified to the values ​​shown in Table 2 according to the different fuel tank oil levels, where Table 2 is the sensor resistance table for model 2.

[0033] Table 2

[0034]

[0035] Therefore, the sensor components are redesigned for each model in the related technology, and the resistance range and key resistance values ​​are different, which brings a lot of repetitive development work. Not only that, these parameters need to be output to the fuel meter, and each time the engineers need to redesign the resistance detection circuit, conversion algorithm, etc. of the fuel meter according to the different parameters.

[0036] In order to solve this problem, an embodiment of the present application proposes a method for designing the resistance of an automobile fuel pump sensor, which can solve the problem that the resistance ranges and key point resistance settings of sensors of different vehicle models are different, and unify the sensor resistance design of all vehicle models. This method will be described in detail below.

[0037] The following describes the fuel pump sensor resistance design method, device, sensor, vehicle and medium of the embodiment of the present application with reference to the accompanying drawings. In view of the fact that the resistance ranges and key point resistances of different sensor components of different vehicle models mentioned in the above background technology are different, it is necessary to redesign the detection circuit and conversion algorithm of the fuel meter, which adds additional workload and complexity. The present application provides a fuel pump sensor resistance design method. In this method, the target design quantity and target design requirements of the fuel pump sensor are determined according to the vehicle type of the target vehicle, and the sensor resistance detection circuit is designed. The resistance table of the fuel pump sensor of the target vehicle is generated by the three together, which can solve the problem that the resistance ranges and key point resistance settings of sensors of different vehicle models are different, unify the sensor resistance design of all vehicle models, and greatly reduce repetitive design work. As a result, the problem that the resistance ranges and key point resistances of different sensor components of different vehicle models are different, the detection circuit and conversion algorithm of the fuel meter need to be redesigned, which adds additional workload and complexity is solved.

[0038] Specifically, Figure 1 A schematic flow chart of a method for designing the resistance of a fuel pump sensor provided in an embodiment of the present application.

[0039] like Figure 1 As shown, the fuel pump sensor resistance design method includes the following steps:

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

[0041] Among them, identification can be through manual input, sensor recognition, etc.; vehicle types include sedans or compact cars, SUVs or trucks, and high-performance vehicles, etc.

[0042] It is understandable that different vehicle types will lead to different fuel tank oil levels, which will lead to differences in sensor components. The embodiments of the present application can identify the vehicle type of the target vehicle through manual input, sensor recognition, etc.

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

[0044] It is understandable that the target design quantity of fuel pump sensors needs to be determined according to the vehicle type. For example, sedans or compact cars usually have only one fuel tank and only need one fuel pump sensor; SUVs or trucks may have larger fuel tanks or dual tank designs, requiring more sensors; high-performance vehicles may use multiple fuel pumps to ensure a stable fuel supply, so more sensors may be required; target design requirements include resistance range, etc.

[0045] In step S103, a resistance table of the fuel pump sensor of the target vehicle is generated according to the target design quantity, the target design requirement and the sensor resistance detection circuit.

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

[0047] It can be understood that after the embodiment of the present application determines the target design quantity and target design requirements of the fuel pump sensor, the sensor resistance detection circuit is designed according to data such as the number of sensor fuel pump sensors of the vehicle type, the sensor resistance range, etc., and a resistance table of the fuel pump sensor of the target vehicle is generated according to the target design quantity, target design requirements and the sensor resistance detection circuit.

[0048] In an embodiment of the present application, a resistance table of a fuel pump sensor of a target vehicle is generated according to a target design quantity, a target design requirement, and a sensor resistance detection circuit, including: if the target design quantity is one, identifying the target design requirement to determine a fixed resistance corresponding to a unit volume, and determining a sensor resistance range according to the sensor resistance detection circuit; and designing a resistance table of the fuel pump sensor of the target vehicle according to the fixed resistance corresponding to the unit volume and the sensor resistance range.

[0049] It can be understood that after the target design quantity and target design requirements of the fuel pump sensor are determined and the sensor resistance detection circuit is designed, if the target design quantity is one, the fixed resistance corresponding to the unit volume is determined according to the target design requirement, and finally the resistance table of the fuel pump sensor of the target vehicle is designed according to the fixed resistance corresponding to the unit volume and the sensor resistance range.

[0050] For example, if 3Ω is set for every 1L of fuel and the sensor resistance range is 80Ω to 380Ω, then the fuel pump sensor resistance can be set to 380Ω when the fuel tank is empty, and the fuel pump sensor resistance decreases by 3Ω for every additional liter of fuel. When the fuel tank is full, the fuel pump sensor resistance is 80Ω. Some key resistance points can be set during the resistance change process. For example, when only 15L of fuel is left, the fuel pump sensor resistance corresponds to 335Ω, which is set as the alarm point, thereby generating a resistance table of the fuel pump sensor of the target vehicle.

[0051] In an embodiment of the present application, a resistance table of a fuel pump sensor of a target vehicle is generated according to a target design quantity, a target design requirement, and a sensor resistance detection circuit, including: if the target design quantity is two, identifying the target design requirement to determine a fixed resistance corresponding to a unit volume, and determining a total sensor resistance range according to the sensor resistance detection circuit; determining respective resistance ranges of the two sensors according to a ratio of the fuel amounts in the primary and secondary chambers of the fuel tank and the total sensor resistance range; and designing a resistance table of the fuel pump sensor of the target vehicle according to the fixed resistance corresponding to the unit volume and the respective resistance ranges of the two sensors.

[0052] It can be understood that if the target design quantity is two, then according to the target design requirements, the method of unit volume corresponding to fixed resistance is used to determine the fixed resistance corresponding to the unit volume, and then the fuel amount ratio of the main and sub-chambers of the fuel tank is obtained, and the resistance range of each of the two sensors is determined according to the fuel amount ratio and the total sensor resistance range. Finally, the resistance table of the fuel pump sensor of the target vehicle is designed according to the fixed resistance corresponding to the unit volume and the sensor resistance range.

[0053] For example, it is set that each 1L of fuel corresponds to 3Ω, the fuel volume of the main and auxiliary chambers of the fuel tank is 4:1, and the total sensor resistance range is 80Ω~380Ω, that is, the resistance range of the two sensors added is 80Ω~380Ω. According to the proportional distribution, the resistance range of the main chamber sensor 1 can be 40Ω~280Ω, and the resistance range of the auxiliary chamber sensor 2 can be 40Ω~100Ω. Then, when the fuel tank is empty, the fuel pump sensor resistance can be set to 380Ω, the sensor 1 resistance to 280Ω, and the sensor 2 resistance to 100Ω. For every additional liter of fuel, the total fuel pump sensor resistance decreases by 3Ω; when the fuel tank is full, the fuel pump sensor resistance is 80Ω, the sensor 1 resistance is 40Ω, and the sensor 2 resistance is 40Ω. In the process of resistance change, some key resistance points can be set. For example, when there is only 15L of fuel left in the fuel tank, the total fuel pump sensor resistance corresponds to 335Ω, which is set as an alarm point, thereby generating a resistance table of the fuel pump sensor of the target vehicle.

[0054] In an embodiment of the present application, before generating a resistance table of a fuel pump sensor of a target vehicle according to a target design quantity, a target design requirement and a sensor resistance detection circuit, the method includes: identifying current data and resistance data in relevant data of fuel pump sensors of multiple vehicle types; designing a rated current range of the sensor resistance detection circuit according to the current data, and designing a rated resistance range of the sensor resistance detection circuit according to the resistance data and the number of sensors; calculating the protection resistor resistance of the sensor resistance detection circuit according to the rated current range and the rated current ranges corresponding to different numbers of sensors; and designing the sensor resistance detection circuit according to the protection resistor resistance, the rated resistance range and the rated current ranges corresponding to different numbers of sensors.

[0055] Among them, the rated current range of the sensor resistance detection circuit is the current range that satisfies the normal operation of the sensor. If the current exceeds the rated current range, it is easy to cause sensor burning, and if the current is lower than the rated current range, the detection accuracy will decrease. The protection resistor of the detection circuit is used to protect the circuit from being burned out, and 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 can be understood that before the embodiment of the present application generates the resistance table of the fuel pump sensor of the target vehicle according to the target design quantity, target design requirements and the sensor resistance detection circuit, it is necessary to calculate the rated current range, rated resistance range and protection resistor value of the sensor resistance detection circuit according to the relevant data of the vehicle type and its fuel pump sensor, and design the sensor resistance detection circuit based on the three to ensure that the sensor resistance detection circuit can operate safely and normally.

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

[0058] Among them, the software update method can be achieved through OTA (Over-the-Air, air download technology); the resistance band is a resistance band that no longer distinguishes between general resistance bands and key resistance bands. When using this resistance band, it is only necessary to input a new resistance table into the instrument, and the fuel meter can adjust the instrument by updating the software.

[0059] It can be understood that the embodiment of the present application, by applying a newly designed resistance band of the sensor component, can update the software update package of the fuel meter of the target vehicle generated according to the resistance table to the vehicle via OTA, which is quick and convenient, and the fuel meter 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 the embodiment of the present application, the target design quantity and target design requirements of the fuel pump sensor can be determined according to the vehicle type of the target vehicle, and the sensor resistance detection circuit can be designed. By jointly generating a resistance table of the fuel pump sensor of the target vehicle, the problem of different resistance ranges and key point resistance settings of sensors of different vehicle models can be solved, and the sensor resistance design of all vehicle models is unified, which greatly reduces repetitive design work.

[0061] The fuel pump sensor resistance design method proposed in the embodiment of the present application is further described below through a specific embodiment.

[0062] First, we need to design a universal resistance detection circuit. Combined with the actual situation of current sensor component design, the design of the resistance detection circuit is gradually introduced 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 sensor ablation, while 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 of the two resistance bands will be too large. If the range is too small, the process difficulty will be increased because the resistance bands are too dense.

[0066] There are two situations to consider here:

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

[0068] The second case: 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 Rf = Rf1 + Rf2 = 380 Ω.

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

[0070] (4) The basic principle diagram of the sensor resistance detection circuit is as follows Figure 2 , Figure 3 As shown, Figure 2 This is the basic circuit diagram for detecting the resistance of a single sensor. Figure 3 The following are the basic circuit diagrams for two sensor resistance detection circuits. 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] From the information described in (1), (2) and (3), it can be calculated that R=Rd+Rx=U / I=(300-600)Ω.

[0074] (5) After substituting Rx, we get Rd = 220Ω, which is the protection resistor value of the detection circuit. In this way, a fixed sensor resistance detection circuit is obtained.

[0075] Next, we will design the sensor resistance value of a fuel tank with a capacity of 100L according to two cases according to the target design quantity in the fuel tank.

[0076] Case 1: 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, the method of unit volume corresponding to fixed resistance is adopted, and 3Ω is set for every 1L of fuel. Assuming that a 100L fuel tank can travel 1000km, the sensor resistance table shown in Table 3 can be obtained, where Table 3 is a single sensor resistance table.

[0079] Table 3

[0080]

[0081] 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) Two sensors are generally used in saddle-shaped fuel tanks to measure the fuel volume in the two chambers. Figure 4 The figure shows a schematic diagram of a saddle-shaped fuel tank. For the convenience of calculation, it is assumed that the fuel volume of the main and auxiliary chambers V1 / V2 = 4:1, that is, the main chamber V1 = 80L, and the auxiliary chamber V2 = 20L.

[0084] (3) In order to obtain the most accurate display accuracy, the method of unit volume corresponding to fixed resistance is adopted, and 3Ω is set for every 1L of fuel. First, the resistance range of Rx1 and Rx2 is allocated as follows.

[0085] ΔRx1 / V1=ΔRx2 / V2

[0086] (4) After substituting V1 and V2, we can get ΔRx1 = 240Ω, ΔRx2 = 60Ω. Therefore, the resistance range of the two sensors is Rx1 = (40-280)Ω, Rx2 = (40-100)Ω. Assuming that a 100L fuel tank can travel 1000km, we can get 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 table, it is necessary to make some improvements to the resistance band of the previous sensor components. The resistance band of the commonly used sensor components is as follows: Figure 5 As shown. This resistance band is used to distinguish between general resistance bands and key resistance bands, and the design scheme has poor universality. For example, Figure 5 The meter in the figure corresponds to 90% of the rated volume. If you want to adjust the meter to 85% of the rated volume, you must redesign the resistance band and move the key resistance band to 85%. This adjustment requires adjusting the mold, which is costly and takes a long time.

[0090] The resistance range of the newly designed sensor assembly is as follows Figure 6 As shown. No longer distinguishing between general resistance bands and key resistance bands, such a resistance band design scheme has good universality. Figure 5 For example, Figure 5 The meter in the fuel meter corresponds to 90% of the rated volume. If you want to adjust the meter to 85% of the rated volume, you only need to input a new resistance table into the meter and update the software of the fuel meter. This can be achieved through OTA upgrades, which is low cost and short cycle.

[0091] This embodiment designs a universal sensor resistance detection circuit, which no longer needs to be designed separately according to the vehicle model. In the case where there is only one sensor in the fuel tank, the total resistance table of the sensor is universal, and the total resistance table input to the fuel meter and the fuel pump manufacturer is the same; in the case where there are two sensors in the fuel tank, the total resistance table of the sensor is also universal, and the total resistance table input to the fuel meter and the fuel pump manufacturer is also the same. In this way, the problem that the resistance range and key point resistance of sensor components of different vehicle models are different, and the detection circuit and conversion algorithm of the fuel meter need to be redesigned, which adds additional workload and complexity is solved.

[0092] Next, a fuel pump sensor resistance design device according to an embodiment of the present application will be described with reference to the accompanying drawings.

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

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

[0097] In the embodiment of the present application, the design module 203 is further used for: if the target design quantity is two, identifying the target design requirements to determine the fixed resistance corresponding to the unit volume, and determining the total sensor resistance range according to the sensor resistance detection circuit; determining the respective resistance ranges of the two sensors according to the fuel quantity ratio of the main and sub-chambers of the fuel tank according to the fuel quantity ratio and the total sensor resistance range; designing the resistance table of the fuel pump sensor of the target vehicle according to the fixed resistance corresponding to the unit volume and the respective resistance ranges of the two sensors.

[0098] In an embodiment of the present application, the design module 203 is further used to: identify current data and resistance data in relevant data of fuel pump sensors of multiple vehicle types; design a rated current range of the sensor resistance detection circuit according to the current data, and design a rated resistance range of the sensor resistance detection circuit according to the resistance data and the number of sensors; calculate the protection resistor resistance of the sensor resistance detection circuit according to the rated current range and the rated current range corresponding to different numbers of sensors; design the sensor resistance detection circuit according to the protection resistor resistance, the rated resistance range and the rated current range corresponding to different numbers of sensors.

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