Description

Technical Field

[0001] The present application relates to the field of automobile safety, and in particular to intelligent automobile fields such as modern sensing and information fusion. Background Art

[0002] With the continuous development of new energy vehicle related technologies, hybrid models have gained more and more recognition in the market due to their advantages such as low fuel consumption, long driving range and good power. In particular, plug-in hybrid electric vehicles (PHEV) and extended-range electric vehicles (EREV) are increasingly widely used due to the use of high-pressure metal fuel tanks with better pressure resistance and more mature technology. However, despite the above advantages of new energy vehicles, the disadvantage of obvious fuel sloshing noise in the entire vehicle after matching with high-pressure fuel tanks cannot be ignored. In fact, under certain working conditions, drivers and passengers can hear periodic liquid collision and flow sounds, which seriously affects the riding comfort of drivers and passengers. Therefore, testing the noise (sloshing noise) of the vehicle's fuel tank has become one of the important links in evaluating vehicle performance and optimizing the vehicle.

[0003] In related technologies, during the process of simulated vehicle testing, noise is often tested based on the maximum noise value. However, when noise testing based on the maximum noise value is used to evaluate the noise level of fuel impact, the noise attenuation performance cannot be evaluated, resulting in low accuracy of the noise detection results.

[0004] Therefore, how to propose a more accurate and reliable method for detecting noise of a vehicle fuel tank has become an urgent problem to be solved. Summary of the Invention

[0052] The following describes in detail embodiments of the present application, examples of which 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.

[0053] It should be noted that the vehicle fuel tank noise detection method proposed in this application can be applied to a variety of application scenarios, for example, it can be applied to the performance evaluation scenario before the vehicle leaves the factory; for example, it can be applied to the maintenance scenario after the vehicle leaves the factory, etc.

[0054] The noise detection method for a vehicle fuel tank proposed in this application is explained below using a performance evaluation scenario before a vehicle leaves the factory as an example.

[0055] It should be noted that, in the process of simulating the vehicle test, in order to accurately simulate the actual shaking of the fuel in the fuel tank and avoid the influence of other interference noises, in this application, before the vehicle leaves the factory, the following settings can be set: Figure 1 The vehicle fuel tank noise detection system 1000 shown simulates the actual installation of a fuel tank on a vehicle. In other words, the vehicle fuel tank noise detection system 1000 proposed in this application can effectively simulate the shaking noise level of the fuel tank through the noise detection test bench.

[0056] In some embodiments, a noise detection system 1000 for a vehicle fuel tank includes a fuel tank 100 , a noise detection stand 200 , and a noise detection device 300 , wherein the fuel tank 100 is disposed on the noise detection stand 200 .

[0057] The fuel tank 100 is an important component of the vehicle power system and is mainly used to store fuel.

[0058] The noise detection stand 200 carries a fixed fuel tank 100 .

[0059] It should be noted that the above-described vehicle fuel tank noise detection system 1000 is only one possible example. To meet different testing needs, a test vehicle can be added to the vehicle fuel tank noise detection system 1000. The test vehicle is a testing component that simulates the structure of a vehicle, and the noise detection bench 200 can be mounted on the test vehicle.

[0060] It should be noted that for the vehicle fuel tank noise detection system 1000 equipped with a test vehicle, there is no direct physical connection between the fuel tank 100 and the test vehicle. Instead, they are connected via the noise detection stand 200. In other words, the fuel tank 100 is mounted on the noise detection stand 200, which is in turn mounted on the test vehicle.

[0061] The noise detection device 300 refers to a device that can collect noise and identify noise.

[0062] The following describes a method, device, and electronic device for detecting noise in a vehicle fuel tank according to embodiments of the present application with reference to the accompanying drawings.

[0063] Figure 2 FIG. 1 is a flow chart of a noise detection method for a vehicle fuel tank according to an embodiment of the present application. Figure 2 As shown, the method includes:

[0064] S201 , acquiring target operating parameters, and generating a first operating instruction for controlling the operation of a fuel tank according to the target operating parameters, wherein the target operating parameters include an operating speed and an operating distance.

[0065] In the embodiment of the present application, target operating parameters may be acquired, and a first operating instruction for controlling the operation of the fuel tank may be generated according to the target operating parameters, so as to control the fuel tank to operate according to the first operating instruction.

[0066] The target operating parameters include at least operating speed and operating distance.

[0067] For example, the target operating parameters may be set to include an operating speed of 1 m / s and an operating distance of 100 m.

[0068] S202: Acquire noise data of the fuel tank within a target period, where the target period is a preset period after the fuel tank has completed operation according to the first operation instruction.

[0069] The noise data refers to the fuel sloshing noise, that is, the noise generated by the sloshing of the fuel stored in the fuel tank 100 and the liquid hitting the inner wall of the fuel tank.

[0070] The preset time period may be any time period, such as within 10 seconds, within 30 seconds, etc.

[0071] It should be noted that the present application does not limit the specific method for obtaining the noise data of the fuel tank of the test vehicle within the target period, and can be selected according to actual conditions.

[0072] As a possible implementation method, the noise data of the fuel tank 100 can be obtained by using an audio collection device such as a pickup (microphone) installed in a test vehicle.

[0073] As another possible implementation method, the noise data of the fuel tank 100 may be acquired by using an audio collection device such as a pickup (microphone) installed outside the test vehicle.

[0074] S203: Draw a noise waveform diagram according to the target period and the noise data, and perform noise detection on the fuel tank according to the noise peak data in the noise waveform diagram.

[0075] It should be noted that in the related art, during the process of simulating the noise detection of the vehicle fuel tank, the noise is usually detected based on the maximum noise value, which leads to low accuracy and poor reliability of the noise detection results.

[0076] Therefore, this application no longer relies on the maximum noise value as a basis. After obtaining the target time period and noise data, a noise waveform can be drawn according to the target time period and noise data, and the noise of the fuel tank can be detected by obtaining the noise data change law presented by the waveform.

[0077] It should be noted that the present application does not limit the specific method of performing noise detection on the fuel tank based on the noise peak data in the noise waveform diagram, and can be selected according to actual conditions.

[0078] As a possible implementation method, each peak in the noise waveform can be obtained, and the noise of the fuel tank can be detected based on all the peaks.

[0079] A crest is the maximum amplitude within a wavelength, while the corresponding minimum amplitude is called a trough. For example, in a transverse wave, the highest point is the crest, while the lowest point is the trough. Furthermore, the point where a wave causes the greatest positive displacement is represented by a high point on the wave curve.

[0080] As another possible implementation method, part of the peaks (at least one peak) in the noise waveform diagram may be obtained, and noise detection may be performed on the fuel tank based on the part of the peaks.

[0081] Therefore, the present application proposes a vehicle fuel tank noise detection method. This method can obtain target operating parameters and generate a first operating instruction for controlling the operation of the fuel tank based on the target operating parameters. The target operating parameters include operating speed and operating distance. The noise data of the fuel tank within a target period is then obtained. The target period is a preset period after the fuel tank has completed operation according to the first operating instruction. A noise waveform is then drawn based on the target period and the noise data, and the fuel tank noise is detected based on the noise peak data in the noise waveform. Therefore, the present application no longer relies on the maximum noise value as the basis for noise detection. Instead, a noise waveform that can reflect the noise level of the fuel tank within the target period is used to evaluate the sensory impact of the fuel tank sloshing noise on the driver and passengers, thereby improving the accuracy and reliability of the noise detection results.

[0082] In the present application, when noise detection is performed on the fuel tank based on the noise waveform diagram, the peak data in the noise waveform diagram may be analyzed.

[0083] As a possible implementation, Figure 3As shown, based on the above embodiment, the specific process of performing noise detection on the fuel tank according to the noise peak data in the noise waveform diagram in the above step S203 includes the following steps:

[0084] S301: Obtain a first preset noise threshold, and determine the number of noise peak data smaller than the first preset noise threshold in a noise waveform graph.

[0085] It should be noted that after drawing the noise waveform, optionally, at least one noise peak data generated by the fuel tank 100 after the stop moment can be obtained according to the noise waveform. For example, two noise peak data generated by the fuel tank 100 after the stop moment can be obtained; for example, Figure 4 As shown, all noise peak data generated by the fuel tank 100 after the stop moment can be obtained.

[0086] Furthermore, a first preset noise threshold may be obtained.

[0087] It should be noted that, in the present application, different first preset noise thresholds are set according to the different stages that the fuel tank 100 is in after being stationary.

[0088] For example, the first preset noise threshold corresponding to the first noise peak data generated by the fuel tank 100 after the moment of stopping can be set to 60 decibels (dB), the first preset noise threshold corresponding to the second noise peak data generated by the fuel tank 100 after the moment of stopping can be set to 45 decibels, and the first preset noise threshold corresponding to the third noise peak data generated by the fuel tank 100 after the moment of stopping can be set to 40 decibels.

[0089] Furthermore, the number of noise peak data smaller than a first preset noise threshold in the noise waveform graph may be determined.

[0090] For example, if Figure 4 As shown, due to the noise peak data corresponding to the moment when the fuel tank 100 stops (i.e. Figure 4 If the first noise peak data in the noise test is less than the corresponding first preset noise threshold of 60 decibels, the second noise peak data generated by the fuel tank 100 immediately after stopping is less than the corresponding first preset noise threshold of 45 decibels, and the third noise peak data generated by the fuel tank 100 immediately after stopping is less than the corresponding first preset noise threshold of 40 decibels, then the number of noise peak data less than the first preset noise threshold is 3. If the number reaches the preset number threshold, then the noise test result of the fuel tank is determined to be qualified.

[0091] The preset number threshold can be set according to actual conditions. For example, the preset number threshold can be set to 3.

[0092] For example, if the number of noise peak data in the noise waveform that is smaller than the first preset noise threshold is 3, and the preset number threshold is 3, then the number reaches the preset number threshold, and it can be determined that the noise detection result of the fuel tank is qualified.

[0093] S303: If the number does not reach the preset threshold, determine that the noise detection result of the fuel tank is unqualified.

[0094] For example, if the number of noise peak data in the noise waveform that is smaller than the first preset noise threshold is 2, and the preset number threshold is 3, at this time, the number does not reach the preset number threshold, then it can be determined that the noise detection result of the fuel tank is unqualified.

[0095] S304: Generate and send a design optimization reminder for the fuel tank.

[0096] It should be noted that after executing step S303, a design optimization reminder for the fuel tank may be generated and sent.

[0097] As a possible implementation method, the generated design optimization reminder for the fuel tank can be sent to target users.

[0098] It should be noted that the selection and number of target users are not limited in this application and can be set according to actual conditions.

[0099] Optionally, the target user may be set as at least one relevant staff member, so that all relevant staff members receive the design optimization reminder and optimize the fuel tank according to the design optimization reminder.

[0100] Thus, the vehicle fuel tank noise detection method provided in this application can determine whether the fuel tank noise detection result is qualified by obtaining a first preset noise threshold and determining the number of noise peak data in a noise waveform that is less than the first preset noise threshold. Based on the number and the preset threshold, the method can determine whether the fuel tank noise detection result is qualified. Alternatively, if the number reaches the preset threshold, the fuel tank noise detection result is determined to be qualified; if the number does not reach the preset threshold, the fuel tank noise detection result is determined to be unqualified. After determining that the fuel tank noise detection result is unqualified, a design optimization reminder for the fuel tank can be generated and sent. This avoids errors caused by relying solely on a single peak data point for noise judgment and improves the accuracy of the fuel tank noise detection result. Furthermore, by sending the optimization reminder for the fuel tank, relevant personnel can promptly understand the fuel tank noise detection results and perform corresponding optimization processing, thereby improving the intelligence level of the fuel tank noise detection process.

[0101] It should be noted that, in this application, before obtaining the target operating parameters, a certain liquid may be injected into the fuel tank. In order to ensure the safety of the detection process, the liquid may be a non-flammable liquid.

[0102] As a possible implementation, Figure 5 As shown, based on the above embodiment, the specific process before obtaining the target operating parameters includes the following steps:

[0103] S501: Obtain the rated capacity of the fuel tank, and obtain the target volume based on the rated capacity.

[0104] It should be noted that the present application does not limit the specific method of obtaining the target volume based on the rated volume, and it can be selected according to actual conditions.

[0105] As a possible implementation manner, a preset ratio / percentage may be obtained, and then the target volume may be obtained based on the rated volume and the preset ratio / preset percentage.

[0106] For example, if the rated capacity of the fuel tank 100 is V and the preset percentage is 50%, in this case, the target volume is 50%*V.

[0107] S502: Generate a liquid injection instruction according to the target volume, so as to inject the target volume of non-flammable liquid into the fuel tank.

[0108] Among them, non-flammable liquid, also known as incombustible liquid, refers to a liquid that cannot burn and has good degreasing performance.

[0109] It should be noted that this application comprehensively considers the impact of different volumes of non-flammable liquid in the fuel tank on the noise generated by the fuel tank. Optionally, before obtaining the target operating parameters, that is, before the first test of the fuel tank, a target volume of non-flammable liquid can be injected into the fuel tank. Furthermore, after generating a liquid injection instruction based on the target volume to inject the target volume of non-flammable liquid into the fuel tank, that is, after the initial filling of the fuel tank, the volume of non-flammable liquid in the fuel tank can be adjusted.

[0110] As a possible implementation, Figure 6 As shown, based on the above embodiment, generating a liquid injection instruction according to the target volume so as to inject the target volume of non-flammable liquid into the fuel tank specifically includes the following steps:

[0111] S601: Determine, based on the target operating stage, the target driving direction, the target number of tests, and the first operating instruction, that after the fuel tank is controlled to operate, the target volume is reacquired.

[0112] It should be noted that the newly acquired target volume is inconsistent with the target volume acquired last time. Optionally, the newly acquired target volume can be set to be larger than the target volume acquired last time; optionally, the newly acquired target volume can be set to be smaller than the target volume acquired last time.

[0113] For example, if 50%*V of non-flammable liquid was injected into the fuel tank before the last trip, in this case, the re-acquired target volume can be set to 60%*V, 70%*V, 80%*V, or any other volume inconsistent with 50%*V.

[0114] S602: Regenerate a liquid injection instruction according to the newly acquired target volume, so that the fuel tank is injected with the newly acquired target volume of non-flammable liquid.

[0115] In the embodiment of the present application, after the target volume is obtained, a liquid injection instruction may be regenerated to inject the non-flammable liquid of the obtained target volume into the fuel tank 100 .

[0116] Therefore, the vehicle fuel tank noise detection method proposed in this application can obtain the rated capacity of the fuel tank, and based on the rated capacity, obtain a target volume, and then generate a liquid injection instruction based on the target volume to inject the target volume of non-flammable liquid into the fuel tank. Furthermore, the target volume can be re-obtained in response to different driving instructions, and the liquid injection instruction can be re-generated based on the re-obtained target volume to inject the re-obtained target volume of non-flammable liquid into the fuel tank. This noise detection is performed by comprehensively considering the impact of different volumes of non-flammable liquid in the fuel tank on the noise generated by the fuel tank, simulating the actual driving scene of the vehicle after leaving the factory as much as possible, and further improving the accuracy and reliability of the vehicle fuel tank noise detection process.

[0117] It should be noted that, in the present application, after the first operating instruction for controlling the operation of the fuel tank is generated according to the target operating parameters, parameters such as test variables may be further added.

[0118] As a possible implementation, Figure 7 As shown, based on the above embodiment, the following steps are specifically included after generating the first operation instruction for controlling the operation of the fuel tank according to the target operation parameter:

[0119] S701. Obtain a target operating phase, a target driving direction, and a target number of tests.

[0120] The target operation phase may be any of the following operation phases: a deceleration phase, an acceleration followed by deceleration phase, etc.

[0121] Among them, the deceleration stage refers to the process in which the running speed of the fuel tank gradually decreases from a certain value to 0, which mostly occurs during the braking process.

[0122] For example, if Figure 8 As shown, the target operation phase can be set as a deceleration phase. In this case, during the target operation phase, the operating speed of the fuel tank is gradually reduced from 3.5 km / h to 0 km / h.

[0123] Among them, the stage of first accelerating and then decelerating refers to the process in which the running speed of the fuel tank gradually increases from 0 and then gradually decreases, which mostly exists in the complete driving process from starting to braking.

[0124] For example, if Figure 9 As shown, the target operation phase can be set as an acceleration followed by a deceleration phase. In this case, within the target operation phase, the operating speed of the fuel tank increases from 0 km / h to 7.5 km / h, and then decreases from 7.5 km / h to 0 km / h.

[0125] Among them, the target test number can be set to 6 times, 10 times, etc.; the target driving direction can be set to forward or backward.

[0126] S702: Control the operation of the fuel tank according to the target operation phase, the target driving direction, the target number of tests, and the first operation instruction.

[0127] It should be noted that the complete process of noise detection for any fuel tank may include multiple detection stages.

[0128] For example, the noise detection process for fuel tank A can be divided into two phases. For the first phase, the target operating phase can be set as acceleration followed by deceleration, the target driving direction can be set as forward, and the target number of tests can be set as six. The first operating instruction specifies an operating speed of 1 m / s and a running distance of 100 m. In this case, the fuel tank can be controlled to perform the first phase of operation based on the target operating phase, target driving direction, target number of tests, and the first operating instruction. For the second phase, the target operating phase can be set as acceleration followed by deceleration, the target driving direction can be set as reverse, and the target number of tests can be set as six. The first operating instruction specifies an operating speed of 1 m / s and a running distance of 100 m. In this case, the fuel tank can be controlled to perform the second phase of operation based on the target operating phase, target driving direction, target number of tests, and the first operating instruction. In this case, only the target driving direction is inconsistent.

[0129] For another example, for fuel tank A, its noise detection process can be divided into three stages. For the first stage, the target operation stage can be set as the acceleration stage, the target driving direction can be set as the forward direction, the target test number can be set as 6 times, and the first operation instruction limits the operation speed to 1m / s and the operation distance to 100m. In this case, the fuel tank can be controlled to perform the first stage of operation according to the target operation stage, target driving direction, target test number and the first operation instruction; for the second stage, the target operation stage can be set as the acceleration followed by deceleration stage, the target driving direction can be set as the forward direction, the target test number can be set as 6 times, and the first operation instruction can be set as the acceleration followed by deceleration stage. In one operation instruction, the operating speed is limited to 1m / s and the operating distance is 100m. In this case, the fuel tank can be controlled to perform the second stage of operation based on the target operating phase, target driving direction, target number of tests, and the first operation instruction. For the third stage, the target operating phase can be set to deceleration, the target driving direction can be set to forward, and the target number of tests can be set to 6. The first operation instruction also limits the operating speed to 1m / s and the operating distance to 100m. In this case, the fuel tank can be controlled to perform the second stage of operation based on the target operating phase, target driving direction, target number of tests, and the first operation instruction. In this case, only the target operating phase is inconsistent.

[0130] Furthermore, in order to improve the intelligence level of noise detection of the fuel tank, a second operation instruction for the fuel tank may be generated.

[0131] As a possible implementation, Figure 8 As shown, based on the above embodiment, according to the target operating stage, the target driving direction, the target number of tests and the first operating instruction, the following steps are specifically included in controlling the operation of the fuel tank:

[0132] S801. Obtain the initial position of the fuel tank.

[0133] The initial position refers to the starting point of the fuel tank operation and can be set according to actual conditions. For example, the initial position can be set to the midpoint of the noise detection bench 200.

[0134] S802: Generate a second operation instruction for controlling the operation of the fuel tank according to the initial position, so that the fuel tank runs to the initial position according to the second operation instruction.

[0135] The second operation instruction includes the initial position. In this way, after the second operation instruction is generated, the fuel tank can be moved back to the initial position according to the second operation instruction.

[0136] Therefore, the present application proposes a noise detection method for a vehicle fuel tank, which can obtain the initial position of the fuel tank and generate a second operating instruction for controlling the operation of the fuel tank based on the initial position, so that the fuel tank can run to the initial position according to the second operating instruction, thereby reducing the problems of low efficiency and low accuracy caused by manual movement of the fuel tank, weakening the requirements for the detection site, and improving the intelligence level of fuel tank noise detection.

[0137] It should be noted that, in the present application, when drawing the noise waveform diagram according to the target time period and noise data, the noise data may be processed first.

[0138] As a possible implementation, Figure 9 As shown, based on the above embodiment, the specific process of drawing the noise waveform according to the target period and noise data includes the following steps:

[0139] S901 : Process the noise data based on the least mean square algorithm LMS to obtain processed target noise data.

[0140] Among them, the least mean square algorithm (Least Mean Square, referred to as LMS) is an improved algorithm of the steepest descent algorithm, which is an optimized extension of the steepest descent method applied to the Wiener filter theory.

[0141] S902: Draw a noise waveform diagram according to the target time period and target noise data.

[0142] It should be noted that, in the present application, in order to ensure the accuracy of the noise detection results, multiple parameters can also be monitored in real time at different stages of the detection.

[0143] Optionally, at least one of the following data may be identified: vibration data at the time when the fuel tank operation is completed, and noise data at the time when the fuel tank operation is completed.

[0144] As a possible implementation method, the vibration data of the fuel tank at the time of completion of operation is Figure 10 As shown, based on the above embodiment, the specific process before obtaining the noise data of the fuel tank within the target period includes the following steps:

[0145] S1001. Obtain vibration data of the fuel tank at the time of completion of operation.

[0146] S1002: If the vibration data exceeds the vibration data threshold, reacquire the target operating parameters.

[0147] It should be noted that in this application, if the acquired vibration data exceeds the vibration data threshold, it indicates that the vibration amplitude of the fuel tank's vibration data at the time of completion of operation does not meet the requirements, which is likely to have a significant impact on the current test results. In this case, if the vibration data is determined to have exceeded the vibration data threshold, the target operating parameters can be re-acquired. Furthermore, a design optimization reminder for the detection system 1000 and / or the fuel tank 100 can be generated.

[0148] The vibration data threshold can be set according to actual conditions. For example, the vibration data threshold can be set to 1dB, 0.1dB, 0dB, etc.

[0149] For example, if the vibration data threshold is 0 dB, in this case, the vibration data at the time when the fuel tank operation is completed can be obtained, and it can be determined that the vibration data does not exceed 0 dB, that is, it is ensured that no slight shaking occurs at the time when the fuel tank operation is completed.

[0150] As a possible implementation method, the noise data at the time when the fuel tank operation is completed is as follows: Figure 11 As shown, based on the above embodiment, the specific process after obtaining the noise data of the fuel tank within the target period includes the following steps:

[0151] S1101. Acquire noise data at the moment when the fuel tank operation is completed.

[0152] S1102: Acquire background noise in a target area around the fuel tank.

[0153] S1103: If the noise data at the time of operation completion is greater than the second preset noise threshold and / or the background noise is greater than the preset background noise threshold, reacquire the noise data of the fuel tank within the target period.

[0154] As a possible implementation, if the noise data at the time of operation completion is greater than a second preset noise threshold, the noise data of the fuel tank within the target period is re-acquired.

[0155] It should be noted that in this application, if the acquired noise data exceeds the second noise data threshold, it indicates that the noise level at the time of fuel tank operation completion does not meet the requirements, which is likely to have a significant impact on the test results. In this case, if the noise data is determined to have exceeded the second noise data threshold, the noise data of the fuel tank for the target period can be reacquired. Furthermore, a noise optimization reminder for fuel tank 100 can be generated.

[0156] The second noise data threshold can be set according to actual conditions. For example, the second noise data threshold can be set to 1dB, 0.1dB, 0dB, etc.

[0157] For example, if the second noise data threshold is 0dB, in this case, the noise data of the fuel tank 100 at the time of completion of operation can be obtained. Optionally, it is determined that the noise data is not greater than 0dB, that is, it is ensured that the noise at the time of completion of operation of the fuel tank 100 meets the requirements; optionally, it is determined that the noise data is greater than 0dB, which means that the noise at the time of completion of operation of the fuel tank 100 does not meet the requirements.

[0158] As a possible implementation manner, if the background noise is greater than a preset background noise threshold, the noise data of the fuel tank within the target period is re-acquired.

[0159] It should be noted that, in this application, if the background noise detected exceeds the background noise threshold, it indicates that the background noise level of the fuel tank 100 during noise detection does not meet the requirements, which is likely to have a significant impact on the detection results. In this case, if it is determined that the background noise level is not less than or equal to the preset background noise threshold, the noise data of the fuel tank for the target period can be re-obtained. Furthermore, a noise reduction reminder for the target area can be generated and sent.

[0160] The background noise threshold can be set according to actual conditions. For example, the background noise threshold can be set to 1dB, 0.1dB, 0dB, etc.

[0161] For example, if the background noise threshold is 0dB, in this case, the background noise can be obtained. Optionally, it is determined that the background noise is less than or equal to 0dB, that is, it is ensured that the background noise meets the requirements during the noise detection of the fuel tank 100; optionally, it is determined that the background noise is greater than 0dB, which means that the background noise does not meet the requirements during the noise detection of the fuel tank 100.

[0162] To summarize, after the noise detection system 1000 for the vehicle fuel tank is built, that is, after the fuel tank 100 is placed on the noise detection stand 200, and the noise collection unit in the noise detection device 300 is respectively placed at a first preset distance from the front surface of the fuel tank 100, a second preset distance from the upper surface of the fuel tank 100, and a third preset distance from the rear surface of the fuel tank 100, and at the second preset distance from the upper surface of the fuel tank 100, it is still necessary to inject liquid into the fuel tank 100 to simulate the fuel carrying conditions in the fuel tank 100 during actual driving of the vehicle.

[0163] In some embodiments, the fuel tank 100 includes a fuel pump, a fuel filling pipe, and a vent pipe, wherein the interfaces of the fuel pump, the fuel filling pipe, and the vent pipe are all sealed.

[0164] It should be noted that since the sealing of the fuel tank 100 will affect the noise test result of the fuel tank 100, the fuel tank 100 must pass the sealing test before it can be installed and fixed on the noise test bench 200 for subsequent testing.

[0165] The noise collection unit is explained below using only one noise collection unit consisting of two microphones.

[0166] The noise detection device 300 includes a set of noise collection units, each of which includes two microphones arranged symmetrically about the centerline of the fuel tank 100. One microphone 300-3 is located at a first predetermined distance from the front surface of the fuel tank and a second predetermined distance from the top surface of the fuel tank 100. The other microphone 300-4 is located at a third predetermined distance from the rear surface of the fuel tank and a second predetermined distance from the top surface of the fuel tank.

[0167] It should be noted that to improve the accuracy of noise data collected from fuel tank 100, microphones 300-3 and 300-4 need not be in direct contact with fuel tank 100. Specifically, microphone 300-3 is spaced a first preset distance from the front surface of fuel tank 100 and a second preset distance from the top surface of fuel tank 100. Simultaneously, microphone 300-4 is spaced a third preset distance from the rear surface of fuel tank 100 and a second preset distance from the top surface of fuel tank 100. In this case, microphones 300-3 and 300-4 are spaced the same distance from the top surface of fuel tank 100.

[0168] It should be noted that the present application does not limit the settings of the first preset distance, the second preset distance, and the third preset distance, and they can be selected according to actual conditions.

[0169] Alternatively, the first preset distance may be 100 mm, the second preset distance may be 100 mm, and the third preset distance may be 100 mm. Specifically, microphone 300-3 may be positioned 100 mm from the front surface of fuel tank 100 and a second preset distance of 100 mm from the top surface of fuel tank 100, while microphone 300-4 may be positioned 100 mm from the rear surface of fuel tank 100 and a third preset distance of 100 mm from the top surface of fuel tank 100.

[0170] In this way, additional shaking noise caused by directly fixing the microphones 300 - 3 and 300 - 4 on the fuel tank 100 is avoided.

[0171] For example, during the operation of the fuel tank 100, if the microphones 300-3 and 300-4 are shaken violently due to reasons such as loose fixing, in this case, the noise data of the fuel tank 100 will not increase due to the direct contact between the microphones 300-3 and 300-4 and the fuel tank 100.

[0172] As a result, the vehicle fuel tank noise detection method provided by this application no longer relies on maximum noise levels as the basis for noise detection. Instead, it uses a noise waveform that reflects the noise level of the fuel tank during a target period to assess the sensory impact of fuel tank sloshing noise on the driver and passengers, thereby improving the reliability of noise detection results. Furthermore, by avoiding the generation of additional sloshing noise, the accuracy of noise detection results is further improved.

[0173] Figure 12 This is a structural diagram of a noise detection device for a vehicle fuel tank according to an embodiment of the present application. Figure 12 As shown, the noise detection device 2000 for a vehicle fuel tank includes a generating module 11, an acquiring module 12, and a detecting module 13, wherein:

[0174] A generating module 11 is configured to obtain target operating parameters and generate a first operating instruction for controlling the operation of the fuel tank according to the target operating parameters, wherein the target operating parameters include an operating speed and an operating distance;

[0175] an acquisition module 12, configured to acquire noise data of the fuel tank within a target period, wherein the target period is a preset period after the fuel tank has completed operation according to the first operation instruction;

[0176] The detection module 13 is configured to draw a noise waveform diagram according to the target period and the noise data, and perform noise detection on the fuel tank according to noise peak data in the noise waveform diagram.

[0177] In the embodiment of the present application, the detection module 13 is further used to: obtain a first preset noise threshold and determine the number of noise peak data in the noise waveform that is less than the first preset noise threshold; if the number reaches the preset number threshold, it is determined that the noise detection result of the fuel tank is qualified.

[0178] In the embodiment of the present application, the detection module 13 is further configured to: determine that the noise detection result of the fuel tank is unqualified if the number does not reach the preset number threshold; and generate and send a design optimization reminder for the fuel tank.

[0179] In an embodiment of the present application, the generating module 11 is further configured to: obtain the rated volume of the fuel tank, and obtain a target volume based on the rated volume; and generate a liquid injection instruction based on the target volume so as to inject the target volume of non-flammable liquid into the fuel tank.

[0180] In an embodiment of the present application, the generation module 11 is further used to: obtain the target operating stage, the target driving direction and the target number of tests; and control the operation of the fuel tank according to the target operating stage, the target driving direction, the target number of tests and the first operating instruction.

[0181] In an embodiment of the present application, the generating module 11 is further used to: obtain the initial position of the fuel tank; and generate a second driving instruction for controlling the operation of the fuel tank according to the initial position, so that the fuel tank runs to the initial position according to the second driving instruction.

[0182] In the embodiment of the present application, the generation module 11 is further used to: determine, based on the target operating stage, the target driving direction, the target number of tests and the first operating instruction, to control the fuel tank to operate after completion, and to re-obtain the target volume; and re-generate the injection instruction based on the re-obtained target volume, so that the non-flammable liquid of the re-obtained target volume is injected into the fuel tank.

[0183] In the embodiment of the present application, the detection module 13 is further used to: process the noise data based on the least mean square algorithm LMS to obtain processed target noise data; and draw the noise waveform diagram according to the target time period and the target noise data.

[0184] In the embodiment of the present application, the acquisition module 12 is further configured to: acquire vibration data at the moment when the fuel tank operation is completed; and re-acquire the target operation parameter if the vibration data exceeds a vibration data threshold.

[0185] In the embodiment of the present application, the acquisition module 12 is further used to: obtain noise data at the moment when the fuel tank operation is completed; obtain background noise in a target area around the fuel tank; if the noise data at the moment when the operation is completed is greater than a second preset noise threshold and / or the background noise is greater than a preset background noise threshold, then re-acquire the noise data of the fuel tank within the target time period.

[0186] In the embodiment of the present application, the acquisition module 12 is further configured to: if the background noise is greater than the preset background noise threshold, generate and send a noise reduction reminder for the target area.

[0187] Thus, the vehicle fuel tank noise detection device provided in this application can obtain target operating parameters and generate a first operating instruction for controlling the operation of the fuel tank based on the target operating parameters. The target operating parameters include operating speed and operating distance. The device then obtains noise data from the fuel tank during a target period, which is a preset period after the fuel tank has completed operation according to the first operating instruction. A noise waveform is then drawn based on the target period and the noise data, and noise detection is performed on the fuel tank based on the noise peak data in the noise waveform. Therefore, this application no longer relies on the maximum noise value as the basis for noise detection. Instead, it uses a noise waveform that can reflect the noise level of the fuel tank during the target period to evaluate the sensory impact of the fuel tank sloshing noise on the driver and passengers, thereby improving the accuracy and reliability of the noise detection results.

[0188] To achieve the above embodiments, the present application also provides an electronic device and a computer-readable storage medium.

[0192] By obtaining a target driving strategy and generating a first driving instruction based on the target driving strategy, the test vehicle can be controlled to drive according to the first driving instruction. After determining that the test vehicle has completed driving according to the first driving instruction, noise data of the test vehicle's fuel tank during a target period of time is obtained. A noise waveform graph is then generated based on the target period of time and the noise data to determine whether the fuel tank design meets the noise limit requirements based on the noise waveform graph. As a result, the present application no longer relies on the maximum noise value as the basis for noise detection. Instead, a noise waveform graph that can reflect the noise level of the fuel tank during the target period of time is used to evaluate the sensory impact of fuel tank sloshing noise on the driver and passengers, thereby improving the accuracy and reliability of the noise detection results.
