[0056] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0066] Based on the problems mentioned in the background technology, in related technologies, the air pressure sensor built into the integrated valve is used to detect whether there is a leak in the air circuit. Although this method can achieve basic detection of air circuit leaks in the vehicle's active inflation and deflation system, it still has the problem of low detection efficiency.

[0067] Specifically, current technology falls short in meeting the high-efficiency demands of drivers and repair shops for gas system testing. Drivers often expect quick results during testing, while repair shops desire the ability to rapidly and accurately pinpoint leaks to minimize unnecessary repair time and costs. Furthermore, drivers need to allocate extra time for gas system leak detection during daily use, which undoubtedly negatively impacts the driving experience.

[0068] The inventors discovered the following defects in the current gas circuit self-test:

[0069] 1. Regarding time, the system needs to allow a 5-10 minute buffer period during each initial self-check to observe and record changes in tire pressure in the air circuit. Under the current design, each self-check focuses on a single air circuit. If multiple air circuits are checked comprehensively, the overall time will increase linearly; that is, the number of circuits checked will directly lead to a multiple increase in the required time. While this arrangement ensures the depth of the inspection, it may be slightly time-consuming when facing complex or urgent inspection needs.

[0070] 2. Regarding malfunctions, when the inflation efficiency of the air pump deteriorates, extending the inflation time, the current system may encounter a blind spot: it cannot effectively identify this performance degradation. This could mislead users into attributing the extended time to a leak in the air circuit. Such misjudgment could not only lead users to take unnecessary repair measures but also obscure the actual need for maintenance or replacement of the air pump itself.

[0071] To address the aforementioned issues, this application proposes a gas path detection method, system, device, medium, program product, and vehicle. This application determines the inflation index parameters of the target gas path based on the gas flow rate data of the target gas path to be detected, and determines the detection result of the target gas path based on the inflation index parameters. This allows for rapid determination of the gas path detection result and improves the efficiency of gas path detection.

[0072] Specifically, the gas path detection method in this application can be applied to electronic devices, which can be vehicles or devices installed on vehicles, such as vehicle controllers. The following description uses the vehicle controller as an example to illustrate the various embodiments.

[0073] This application provides a gas path detection method. Please refer to [link / reference]. Figure 1 The gas path detection method provided in this application includes steps S10-S20, which will be described in detail below.

[0074] S10. Determine the inflation index parameters of the target gas path based on the gas flow rate data of the target gas path to be detected.

[0075] In this example, the target gas path is the gas path to be fault-detected. The gas path includes the channel for transmitting gas and the devices through which the gas flows, such as an air pump, rotary seal, and tire. The air pump is typically the starting point of the gas path, and the tire is typically the ending point. Figure 2 As shown, apart from the large dashed line of the combination valve frame, the other dashed lines represent air passages, for example... Figure 2 The dotted line connecting the center left front control valve to the rotary seal corresponding to the left front wheel of the vehicle is the air passage; the actual component is usually a flexible hose.

[0076] In this embodiment, advanced flow rate acquisition technology is integrated, enabling the controller (e.g., vehicle ECU) to capture and record gas flow rate data through the target air passage in real time. Gas flow rate data refers to data related to the detected flow velocity of gas in the target air passage. During the inflation process of the target air passage, the gas flow rate data is recorded. Based on this data, inflation index parameters of the target air passage are determined, characterizing the inflation status of the target air passage during the inflation process.

[0077] S20. Determine the detection result of the target air path based on the inflation index parameters.

[0078] In this embodiment, the detection result of the target air passage can be accurately determined by the inflation index parameters during the inflation process. By introducing flow rate monitoring technology, this embodiment can significantly improve the efficiency of air passage detection, enabling the driver to quickly obtain the detection results. In addition, this embodiment also optimizes the user experience, allowing the driver to enjoy driving without having to spend extra time on separate air passage detection.

[0079] In one embodiment, before determining the inflation index parameters of the target gas path based on the gas flow rate data of the target gas path to be detected, the method further includes:

[0080] In response to a detection command for the target air path, the air pump of the target air path is controlled to inflate.

[0081] While the air pump is inflating, the gas flow rate data of the target air path is acquired.

[0082] In this embodiment, as Figure 2 As shown, a vehicle can include multiple air lines, each corresponding to a tire. The same air pump can be used for all air lines, inflating different tires. The user can select any tire's corresponding air line from among the vehicle's multiple tires to trigger a detection command. Upon receiving the user's trigger command, the system determines the target air line to be detected and, in response to the detection command for the target air line, controls the air pump of that target air line to inflate the tire in that line. Acquiring the gas flow rate data of the target air line during the inflation process provides detailed and accurate data support for subsequent air line detection and analysis.

[0083] In one embodiment, after the air pump controlling the target air path inflates the air, it further includes:

[0084] Obtain the inflation time required for the target air passage to reach the target air pressure during the inflation process;

[0085] If the inflation time is greater than or equal to the preset time, the detection result of the target air path is determined according to the inflation index parameters.

[0086] In this embodiment, the self-test process can be initiated during inflation, comparing and monitoring data in real time to ensure that each step is strictly monitored. During inflation, in addition to acquiring the gas flow rate data of the target air path, the air pressure of the target air path can also be detected in real time. This air pressure mainly refers to the tire pressure of the tire in the target air path. When the target air path reaches the target air pressure, the inflation pump can be controlled to stop inflation. Simultaneously, the inflation time for the target air path to reach the target air pressure is acquired. If the inflation time is greater than or equal to a preset time, it indicates poor inflation performance and a problem in the inflation process. The detection result of the target air path can be determined based on the inflation index parameters of the target air path during inflation.

[0087] In one embodiment, the method further includes:

[0088] If the inflation time is less than the preset time, it is determined that the target air path is not leaking and the inflation pump of the target air path is functioning normally.

[0089] In this implementation, if the inflation time to reach the target air pressure during the inflation process is less than the preset time, it indicates that there is no problem with inflation, and it can be determined that the target air circuit is not leaking and the inflation pump is performing normally (or the inflation pump performance has not decreased).

[0090] In one embodiment, the inflation parameters include total gas flow rate and / or average flow rate.

[0091] In this embodiment, the inflation parameters include the total gas flow rate and / or average flow velocity during the inflation process. The total gas flow rate refers to the total amount of gas flowing through the inflation process, calculated from the gas flow velocity data. The average flow velocity refers to the average flow velocity calculated from the gas flow velocity data throughout the entire inflation process. The detection results of the target gas path can be accurately and quickly analyzed using the total gas flow rate and / or average flow velocity.

[0092] In one embodiment, the gas flow rate data includes gas flow rate data detected from at least one detection location of the target gas path, and determining the inflation index parameters of the target gas path based on the gas flow rate data of the target gas path to be detected includes:

[0093] For each detection location, the inflation index parameters of the detection location in the target gas path are determined based on the gas flow rate data of the detection location.

[0094] In this embodiment, at least one detection position can be set in the target gas path. During the inflation process, detection is performed at each detection position to obtain gas flow rate data at each detection position. The gas flow rate data in the target gas path includes the gas flow rate data detected at at least one detection position. The gas flow rate data at each detection position is processed to determine the gas index parameters at each detection position in the target gas path. Thus, the detection result of the target gas path is determined by the inflation index parameters at at least one detection position, further improving the accuracy of gas path detection.

[0095] In one embodiment, determining the inflation index parameters of the detection location in the target gas path based on the gas flow rate data at the detection location includes:

[0096] The gas flow rate data at the detection location is integrated to determine the total gas flow rate and / or average flow rate at the detection location.

[0097] In this embodiment, gas data at the detection location is collected in real time during the inflation process. Using a precise integral algorithm, not only is the total gas flow rate calculated, but the average flow rate during the current inflation process is also obtained, providing detailed and accurate data support for system analysis.

[0098] In this embodiment, during inflation, real-time inflation parameters can be calculated using an integral algorithm and real-time gas data collected at the detection location. After inflation is complete, the controller can immediately use the latest inflation parameters to quickly obtain the detection results of the target air path. The entire process requires no additional waiting from the user, achieving seamless integration of self-testing and inflation, and greatly improving the user experience.

[0099] In one embodiment, the at least one detection position includes a first detection position and a second detection position, wherein the first detection position is at the air pump of the target air path and the second detection position is at the rotary seal of the target air path.

[0100] In this embodiment, at least one detection position on the target gas path includes a first detection position and a second detection position. The first detection position is located at the air pump of the target gas path, and the second detection position is located at the rotary seal of the target gas path. The gas flow rate data at the first detection position can be acquired by a flow rate acquisition device at the air pump, which can be integrated into the air pump or arranged adjacent to the air pump. The gas flow rate data at the second detection position can be acquired by a flow rate acquisition device at the rotary seal, which can also be integrated into the air pump or arranged adjacent to the air pump.

[0101] In some embodiments, the air pump of the target gas path can be an air pump with a flow rate acquisition device. When the air pump is working, the gas flow rate data at the outlet of the air pump will be acquired in real time. Its main function is to determine whether the air pump has performance degradation or efficiency reduction.

[0102] In some embodiments, the rotary seal of the target gas path can be a rotary seal with a flow rate acquisition device. During inflation, the gas flow rate data passing through the current rotary seal is continuously recorded. After inflation is complete, the average flow rate can be calculated based on the recorded gas flow rate data. This value is mainly used to accurately assess whether there is a potential leak from the inflation pump to the rotary seal. This embodiment represents an advanced transition from a rotary seal to a flow rate acquisition rotary seal. This transition achieves a leap from no data to data, laying a solid foundation for the gas path leak location function.

[0103] In one embodiment, the detection results of the target gas path include the performance detection results of the air pump of the target gas path and the first leakage detection results of the target gas path. The air filling index parameters at the first detection location include the first total gas flow rate and the first average flow rate. The air filling index parameters at the second detection location include the second average flow rate.

[0104] The step of determining the detection result of the target air path based on the inflation index parameters includes:

[0105] The performance test results of the air pump and the first leakage test results are determined based on the first total gas flow rate, the first average flow rate, and the second average flow rate.

[0106] In this embodiment, the first total gas flow rate and the first average flow rate at the first detection location can be obtained based on the gas flow rate data at the first detection location. This is mainly used to assess whether the air pump has performance degradation or efficiency reduction. The second average flow rate at the second detection location can be obtained based on the gas flow rate data at the second detection location. This is mainly used to assess whether there is potential leakage from the air pump to the rotary seal.

[0107] Based on the first total gas flow rate, the first average flow rate, and the second average flow rate, the performance test results of the air pump for the target gas path and the first leakage test results of the target gas path can be determined respectively, and used as the test results of the target gas path.

[0108] In this embodiment, the flow rate-based self-testing method can monitor the status of the target air passage in real time and continuously during inflation, promptly diagnosing any leaks or performance degradation of the air pump. This completely changes the traditional self-testing mode and also determines the air pump's performance status, eliminating the need for users to spend valuable time on additional self-testing procedures, greatly improving user experience and vehicle maintenance convenience.

[0109] In one embodiment, when the first total gas flow rate is within a preset total gas flow range, the first average flow rate is less than the first preset average flow rate, and the second average flow rate is less than the second preset average flow rate, the performance detection result includes a decrease in the performance of the air pump, and the first leakage detection result includes no leakage in the gas path.

[0110] In this embodiment, if the total flow rate of the first gas is within the preset total gas flow range, the first average flow rate is less than the first preset average flow rate, and the second average flow rate is less than the second preset average flow rate, it indicates that the amount of gas provided by the inflation pump during the inflation process is normal. However, if the flow rate of the inflation pump is low and the flow rate at the corresponding rotary seal is also low, it indicates that there is no gas leakage and the performance of the inflation pump is degraded. The performance test results include the degraded performance of the inflation pump, and the first leakage test results include no gas leakage.

[0111] In one embodiment, when the first total gas flow rate is greater than the maximum value of a preset total gas flow range, the first average flow rate is less than a first preset average flow rate, and the second average flow rate is less than a second preset average flow rate, the performance test result includes a decrease in the performance of the air pump, and the first leakage test result includes gas path leakage.

[0112] In this embodiment, if the total flow rate of the first gas is greater than the maximum value of the preset total gas flow range, the first average flow rate is less than the first preset average flow rate, and the second average flow rate is less than the second preset average flow rate, it indicates that the amount of gas provided by the inflation pump during the inflation process is relatively large, but the flow rate of the inflation pump is low and the flow rate at the corresponding rotary seal is also low, indicating gas leakage and performance degradation of the inflation pump. The performance test results include a decrease in the performance of the inflation pump, and the first leakage test results include gas path leakage.

[0113] In one embodiment, when the first total gas flow rate is greater than the maximum value of a preset total gas flow range, the first average flow rate is greater than or equal to a first preset average flow rate, and the second average flow rate is less than a second preset average flow rate, the performance test result includes normal performance of the air pump, and the first leakage test result includes gas path leakage.

[0114] In this embodiment, if the total flow rate of the first gas is greater than the maximum value of the preset total gas flow range, the first average flow rate is greater than or equal to the first preset average flow rate, and the second average flow rate is less than the second preset average flow rate, it indicates that the amount of gas provided by the inflation pump during the inflation process is relatively large and the inflation pump flow rate is normal. However, the flow rate at the corresponding rotary seal is low, indicating that the inflation pump is performing normally but there is a gas leak. Therefore, the performance test results include normal inflation pump performance, and the first leak test results include gas leak.

[0115] In one embodiment, the preset total gas volume range is determined based on the calibrated total gas flow rate at the first detection location, a first boundary coefficient, and a second boundary coefficient;

[0116] The first preset average flow velocity is determined based on the calibrated average flow velocity at the first detection location and the second boundary coefficient; and / or,

[0117] The second preset average flow velocity is determined based on the calibrated average flow velocity at the second detection location and the second boundary coefficient.

[0118] In this embodiment, the preset total gas volume range, the first preset average flow rate, and the first preset average flow rate are all judgment thresholds, which are determined based on calibration data such as the calibration total gas flow rate and calibration average flow rate calibrated for the first detection position (i.e., the air pump) and the calibration average flow rate calibrated for the second detection position (i.e., the rotary seal).

[0119] The calibration data settings described above are highly flexible and adaptable. Their values ​​dynamically adjust according to changes in the selected tire type, number of tires, initial tire pressure, and target tire pressure, ensuring the accuracy and efficiency of subsequent judgment processes. In some embodiments, when a user selects a specific tire, the controller immediately and precisely matches the tire and its current tire pressure with the factory test data to determine various judgment thresholds for the target air circuit corresponding to that tire, thus building a solid data foundation for subsequent analysis and judgment.

[0120] In this embodiment, the first boundary coefficient and the second boundary coefficient can be "1.02" and "0.98" respectively. These two boundary coefficients, serving as the definition of the error range, provide a scientifically rigorous data boundary for the judgment process. Based on this, the system, through a triple independent and complementary judgment mechanism, comprehensively considers multiple factors and arrives at three possible conclusions. This design not only enhances the accuracy and reliability of the judgment but also provides clear guidance and reference for whether to perform secondary self-inspection or professional repair.

[0121] In one embodiment, the first boundary coefficient is greater than the second boundary coefficient.

[0122] In this embodiment, the first boundary coefficient is greater than the second boundary coefficient, which makes the first preset average flow rate and the second preset average flow rate determined based on the second boundary coefficient smaller, so as to accurately determine the gas leakage situation.

[0123] In one example, such as Figure 3As shown, the user selects the target air path to be tested and controls the air pump of the target air path to inflate the corresponding tire. Before inflating, the current tire pressure and current time are recorded. During the inflating process, the total gas flow rate S1, the average flow velocity V1 of the air pump, and the average flow velocity V2 of the rotating seal through the target air path are determined through integral calculation. If the target tire pressure is reached during inflating, the inflating process ends and the inflating time t1 is recorded. The inflating time t1 is compared with the factory-calibrated preset time t1b. When t1 < t1b... 1.02, confirming the target gas path is normal; when t1 ≥ t1b 1.02, then the controller obtains S1, V1, and V2 at the end of inflation. When S1b 1.02≥S1≥S1b 0.98, V1 < V1b 0.98 and V2 < V2b If the value is 0.98, then the target air path is leak-free and the performance of the air pump is reduced; when S1 ≥ S1b 1.02, V1 < V1b 0.98 and V2 < V2b If the value is 0.98, then the target gas path leaks and the performance of the air pump decreases; when S1 ≥ S1b 1.02, V1≥V1b 0.98 and V2 < V2b If the value is 0.98, then the target air circuit is leaking and the air pump is functioning normally.

[0125] In one embodiment, the target gas path includes a target solenoid valve, which divides the target gas path into multiple gas path segments. The method further includes:

[0126] If the first leak detection result includes the gas circuit leak, control the target solenoid valve to be in the closed state;

[0127] Determine the second leak detection result for each gas segment in the target gas path.

[0128] In this embodiment, the target gas path also includes a target solenoid valve. This target solenoid valve is located between the air pump and the end point of the target gas path, and is used to divide the target gas path into multiple gas path segments. It is understood that there can be multiple target solenoid valves; the more target solenoid valves there are, the more finely the target gas path is divided. If the gas path detection result of the target gas path, determined by gas flow rate data, includes a gas path leak, it indicates that the system has initially determined the possibility of a gas path leak and can trigger a self-check procedure to initiate a gas path leak detection. The target solenoid valve in the target gas path can be controlled to be in a closed state. In the closed state, the multiple gas path segments of the target gas path divided by the target solenoid valve are relatively closed, creating a relatively stable detection environment. After the target solenoid valve is in the closed state, the second leak detection result of each gas path segment in the target gas path is determined to characterize whether the gas path segment is located. Therefore, based on the first leak detection result determining a leak in the target gas path, closing the gas path segment by the target solenoid valve can quickly and accurately locate the specific gas path segment with the leak problem, thereby greatly improving the efficiency of fault diagnosis and repair.

[0129] In one embodiment, determining the second leak detection result of the gas path segment in the target gas path includes:

[0130] Obtain the air leakage index parameters of the gas passage section;

[0131] Based on the leakage index parameters, the second leakage detection result of the gas path section is determined.

[0132] In this embodiment, after the target solenoid valve is closed, the leakage index parameters of the gas path section are acquired. These leakage index parameters characterize the gas loss within the closed cavity formed after the target solenoid valve is closed. Based on the leakage index parameters, the second leakage detection result of the gas path section can be determined quickly and accurately.

[0133] In one embodiment, the venting index parameters include pressure change values ​​and / or flow rate values;

[0134] In this embodiment, for each gas path segment, the pressure change value of the gas path segment within a preset time period after the target solenoid valve is closed, and / or the flow rate value of the gas path segment after the target solenoid valve is closed, the flow rate value refers to the absolute value of the gas flow rate data collected for the gas path segment after the target solenoid valve is closed.

[0135] In one embodiment, if the leakage index parameter includes a pressure change value, and the pressure change value is greater than or equal to a preset pressure change value, the second leakage detection result includes leakage in the gas path section.

[0136] In this embodiment, if the leakage index parameter includes the pressure change value, it is determined whether the pressure change value is greater than or equal to the preset pressure change value. Because after the target battery valve is closed, the gas circuit section is relatively stable. When the pressure change value is greater than or equal to the preset pressure change value, it indicates that there is gas leakage in the gas circuit section. The second detection result of the gas circuit section includes gas circuit section leakage.

[0137] In one embodiment, when the leakage index parameter includes a flow rate value and the flow rate value is greater than a preset flow rate value, the second leakage detection result includes leakage in the gas path section.

[0138] In this embodiment, if the leakage index parameter includes the flow rate value, it is determined whether the flow rate value is greater than the preset pressure change value. Because after the target battery valve is closed, the gas path section is relatively stable. When the flow rate value is greater than the preset pressure flow rate value, it indicates that there is a large gas flow in the gas path section. This gas flow is generally caused by gas leakage. Therefore, the second detection result of the gas path section includes gas path section leakage.

[0139] In one embodiment, the method further includes:

[0140] When the vent valve and pressure relief valve in the target gas circuit are closed and the target solenoid valve is open, the air pump in the target gas circuit is controlled to inflate.

[0141] When preset stop conditions are met, the air pump is controlled to stop inflating and the target solenoid valve is controlled to be in a closed state. The preset stop conditions include the target air passage reaching a preset air pressure and / or the inflating time reaching a preset inflating time.

[0142] In this embodiment, before performing the above-mentioned gas path leakage detection, the vent valve and pressure relief valve in the target gas path are first controlled to be in the closed state, and the target solenoid valve is controlled to be in the open state. The vent valve and pressure relief valve are valves that allow gas exchange between the target gas path and the outside world, and the target solenoid valve is a valve that controls the gas exchange inside the target gas path. When the vent valve and pressure relief valve of the target gas path are in the closed state and the target solenoid valve is in the open state, the air pump of the target gas path is controlled to inflate until a preset stop condition is met. The preset stop condition includes the inflating time reaching a preset inflating time and / or the target gas path reaching a preset air pressure, to ensure that sufficient initial air pressure is established in the gas path. When the preset stop conditions are met, the air pump can be controlled to stop air supply and the target solenoid valve can be controlled to be closed. Understandably, at this time, the vent valve and pressure relief valve in the target air circuit are still closed. During this stage, the leakage index parameters of each air circuit section in the target air circuit are determined based on pressure and flow rate acquisition to realize leakage detection of the air circuit section and accurately locate the leakage point in the target air circuit. This process not only improves the detection response speed but also ensures the reliability of the detection results.

[0143] In one example, such as Figure 4 As shown, if the first leak detection result of the target gas path includes a gas path leak, it indicates that a gas path leak has been preliminarily determined. At this time, all solenoid valves in the target gas path except for the vent valve and the exhaust valve (i.e., the target solenoid valves) are opened, the air pump is opened, and after 3 seconds of air inflation, all solenoid valves are closed. The pressure value P1 collected by each pressure acquisition device in the target gas path is recorded. After 10 minutes, the pressure value P2 collected by each pressure acquisition device is recorded. If P1-P2≥1kPa, the gas path section where the pressure acquisition device is located is determined to be leaking; otherwise, the gas path section is not leaking. If there is a gas path section in the target gas path without a pressure acquisition device, the flow rate value collected by the flow rate acquisition device in that gas path section can be observed. If the flow rate value is >0L / min, the gas path section corresponding to that flow rate value is determined to be leaking; otherwise, the gas path section is not leaking.

[0144] In one embodiment, the target solenoid valve includes a first solenoid valve and a second solenoid valve. A first pressure acquisition device is provided in a first air passage between the first solenoid valve and the air pump. A second pressure acquisition device is provided in a second air passage between the first solenoid valve and the second solenoid valve. A flow rate acquisition device is provided in a third air passage between the second solenoid valve and the end point of the target air passage.

[0145] The first pressure acquisition device is used to determine the pressure change value of the first gas path section; the second pressure acquisition device is used to determine the pressure change value of the second gas path section; and the flow rate acquisition device is used to determine the flow rate value of the third gas path section.

[0146] In this embodiment, there are multiple target solenoid valves, including at least a first solenoid valve and a second solenoid valve. According to the inflation sequence of the target gas path, the components of the target gas path are, in sequence, an inflation pump, a first pressure acquisition device, a first solenoid valve, a second pressure acquisition device, a second solenoid valve, a flow rate acquisition device, and the end point of the gas path.

[0147] The first pressure acquisition device is used to detect the pressure value in the first air passage between the first solenoid valve and the air pump, so as to determine the pressure change value of the first air passage within a preset period after the target solenoid valve is closed. The first solenoid valve can also be a pressure acquisition solenoid valve with its own pressure acquisition device. Its own pressure acquisition device can be installed as the first pressure acquisition device on the side close to the air pump. The pressure acquisition solenoid valve is mainly used for self-testing of air leakage, which can quickly and accurately locate the specific air passage with leakage problem, thereby greatly improving the efficiency of fault diagnosis and maintenance.

[0148] The second pressure acquisition device can be used to detect the pressure value in the first air passage between the first solenoid valve and the second solenoid valve, so as to determine the pressure change value of the second air passage within a preset period after the target solenoid valve is closed.

[0149] The flow rate acquisition device can be used to detect the gas flow rate data of the third gas path segment between the second solenoid valve and the end of the gas path, so as to determine the flow rate value of the third gas path segment after the target solenoid valve is closed.

[0150] In one embodiment, the flow rate acquisition device is disposed on the rotary seal and is also used to acquire gas flow rate data at the second detection position.

[0151] In this embodiment, the rotary seal is a mechanical structure added between the tire and the vehicle body. Its function is to prevent the air pipe from rotating when the tire rotates. Since the tire is generally the end point of the air path, the rotary seal is located in the third air path section. The flow rate acquisition device can be set at the rotary seal. In addition to determining the flow rate value of the third air path section, it can also be used to collect the gas flow rate data at the rotary seal in order to determine the first leakage detection result of the target air path.

[0152] In one example, such as Figure 5 As shown, according to the inflation sequence of the target air circuit, the components of the target air circuit are, in order, an air pump (air circuit start point), an air valve, a built-in pressure acquisition device, a left front control valve, a flow rate acquisition rotary seal, a safety valve, a left front wheel, and a tire pressure monitoring sensor. The system includes: an air pump with a flow rate acquisition device for detecting gas flow rate data at the pump outlet; an air valve with a pressure acquisition solenoid valve, whose built-in pressure acquisition device can be installed near the air pump as the first pressure acquisition device to collect the pressure value of the first gas path and determine the pressure change value of the first gas path to determine the second leakage detection result of the first gas path; a built-in pressure acquisition device that can be used as the second pressure acquisition device to collect the pressure value of the second gas path and determine the pressure change value of the second gas path to determine the second leakage detection result of the second gas path; a left front control valve that can be used as the second solenoid valve; and a flow rate acquisition rotary seal with a built-in flow rate acquisition device for detecting gas flow rate data at the rotary seal. This can be used to determine the first leakage detection result of the target gas path and, based on the collected gas flow rate data, to determine the flow rate value of the third gas path to determine the second leakage detection result of the third gas path.

[0153] This application also provides a gas path detection system, including:

Figure 2As shown, the vehicle includes the aforementioned inflation detection gas, which includes at least four air lines with inflation pumps and tires. Each air line shares an inflation pump, inflation valve, deflation valve, venting valve, built-in pressure acquisition device, etc. Each air line can be individually or simultaneously determined as the target air line to be tested according to user needs.

[0155] In one embodiment, the target air path includes an air pump, a first flow rate acquisition device disposed at a first detection position in the target air path, and a second flow rate acquisition device disposed at a second detection position in the target air path. The first detection position is at the air pump in the target air path, and the second detection position is at the rotary seal in the target air path.

[0156] In one embodiment, the target gas path includes a target solenoid valve that divides the target gas path into multiple gas path segments.

A first pressure acquisition device is provided between the first solenoid valve and the air pump, a second pressure acquisition device is provided between the first solenoid valve and the second solenoid valve, and a flow rate acquisition device is provided between the second solenoid valve and the end point of the air path, wherein the flow rate acquisition device is the second flow rate acquisition device.
