[0002] Leakage of the master cylinder assembly and slave cylinder assembly of the clutch system is the root cause of common faults in the clutch system of commercial vehicles, such as clutch slippage, abnormal noise, incomplete clutch separation, and difficulty in starting. Severe leakage of the master cylinder air pressure will cause the clutch system to lose function. Therefore, monitoring the air tightness of the master cylinder and slave cylinder in the clutch system of commercial vehicles is a key link in the fault diagnosis of the clutch system of commercial vehicles, and is also an important step to ensure the safe use of the clutch system of commercial vehicles. At present, the air tightness detection method of the master cylinder and slave cylinder in the clutch system of commercial vehicles mainly relies on manual operation, using an air compressor to inflate the clutch system of commercial vehicles, and judging whether the air tightness of the master cylinder and slave cylinder of the clutch system of commercial vehicles is normal through external auscultation or internal observation.
[0003] However, the existing air tightness detection method has the following problems: 1.

A large amount of compressed gas is consumed in the detection process, and the consumption of compressed gas in the detection process cannot be controlled; 3. The detection result is greatly affected by the external environment, resulting in low accuracy and repeatability of the detection result; 4.

[0027] The method embodiment can be executed in an electronic device or similar computing device in a vehicle including a memory and a processor. For example, Figure 1 As shown, the electronic device of the vehicle may include one or more processors 102 (the processor may include but is not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a field programmable logic device (FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data.

For example, the electronic device of the vehicle may include more or fewer components than those described in the above structure, or may have a configuration different from that described in the above structure.
[0028] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the information processing method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above-mentioned information processing method is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network.

[0030] The display device 110 may be, for example, a touch screen type liquid crystal display (LCD) and a touch display (also referred to as a "touch screen" or a "touch display screen"). The liquid crystal display may enable a user to interact with a user interface of the mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), and a user may interact with the GUI by finger contact and / or gestures on a touch-sensitive surface, wherein the human-computer interaction functions here may optionally include the following interactions: creating web pages, drawing, word processing, making electronic documents, games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music and / or web browsing, etc. The executable instructions for executing the above human-computer interaction functions are configured / stored in a computer program product or a readable storage medium executable by one or more processors.
[0031] The present embodiment provides a control method for a clutch pump body detection device, wherein the clutch pump body includes a master pump and a slave pump connected to the master pump, and the clutch pump body detection device includes a pipeline, and a pressure detection mechanism and a valve switching mechanism are arranged downstream of the pressure detection mechanism on the pipeline. Figure 2 A control method of a clutch pump body detection device according to one embodiment of the present invention is as follows: Figure 2 As shown, the process includes the following steps:
[0032] Step S1: Connect the two ports of the pipeline to the master pump and the slave pump respectively;
[0033] By connecting the test device's pipeline to the master cylinder and slave cylinder, a closed test loop is formed. This loop allows the brake fluid to circulate between the master cylinder, test device and slave cylinder during the test process while keeping the system pressure stable.
[0034] Step S2: Control the valve switching mechanism to be in an open pipeline state, control the clutch pedal to remain in a stepped working state within a preset time period, and detect a first pressure change value of the pipeline within the preset time period through the pressure detection mechanism;
[0035] In this embodiment, the valve switching mechanism uses a high-pressure ball valve and a ball valve handle. The switch of the ball valve can be controlled by simply rotating the handle without complicated operation procedures. The pressure detection mechanism uses a pressure gauge to detect the pipeline pressure. The pressure gauge is connected in the pipeline and can read and display the internal hydraulic pressure in real time. The reading of the pressure gauge is intuitive and easy to understand. Even non-professional maintenance personnel can master its use through training, which reduces the difficulty of operation and improves the portability and practicality of the detection device.
[0036] The operation of the high-pressure ball valve is based on the rotation of the ball. When the hole of the ball is aligned with the input and output ports of the pipeline, the brake fluid can smoothly pass through the ball valve, keeping the hydraulic circuit between the clutch master cylinder and the slave cylinder unobstructed. When the operator rotates the ball 90 degrees by rotating the ball valve handle, the hole and the port are no longer aligned, the flow of brake fluid is blocked, and the pressure inside the hydraulic system is locked, which can be used to detect whether there is pressure relief or air leakage in the system.
[0037] Before starting the test, open the ball valve handle to ensure that the brake fluid can flow freely between the master cylinder and the slave cylinder, creating a stable hydraulic environment for subsequent testing.
[0038] Step S3: controlling the valve switching mechanism to be in a pipeline closing state, controlling the clutch pedal to remain in a stepped working state within a preset time period, and detecting a second pressure change value of the pipeline within the preset time period by the pressure detection mechanism;
[0039] The clutch pedal is controlled to remain pressed for a preset period of time, simulating the condition where the vehicle is static but the clutch system is activated. In this state, the master pump will maintain a certain pressure output without changing due to the continuous movement or release of the pedal, providing a stable environment for testing. At this time, if the high-pressure ball valve is closed, the entire system will form a closed loop, and any slight change in pressure will be captured by the pressure gauge, which helps to more accurately evaluate the system's air tightness.
[0040] When observing the pressure change of the pressure detection mechanism, a preset time period is set. The preset time period provides a unified reference standard so that all detection processes follow the same time parameters, which helps maintain the accuracy and consistency of the detection. The preset time period is usually set relatively short, and does not require long-term observation or waiting. The impact of external factors on the system pressure is also small. The air tightness status of the clutch master cylinder and slave cylinder can be accurately judged in the shortest time, providing a reliable basis for subsequent maintenance decisions.
[0041] Step S4: Generate a clutch detection result based on at least one of the first pressure change value and the second pressure change value, the clutch detection result including at least one of the following: the clutch pump body is qualified, the master pump is depressurized and leaking, and the slave pump is depressurized and leaking.
[0042] Through the above steps, in the embodiment of the present invention, a portable detection device is used to connect the master cylinder and the slave cylinder, and the pressure change is monitored by the valve switching mechanism and the pressure detection mechanism, so as to achieve the purpose of quickly and accurately detecting whether there is pressure relief and air leakage in the master cylinder and the slave cylinder, thereby improving the detection efficiency, reducing unnecessary maintenance hours, ensuring the reliable operation of the vehicle clutch system, and ultimately improving the user's satisfaction with commercial vehicle services and products. This solves the technical problem of low detection efficiency caused by the large size, non-portability and complex operation of the existing detection device.
[0043] Optionally, in some embodiments, connecting the two ports of the pipeline to the master cylinder and the slave cylinder respectively includes: connecting the inlet end of the pipeline to the brake fluid outlet of the master cylinder; connecting the outlet end of the pipeline to the brake fluid outlet of the slave cylinder.
[0044] The inlet end of the pipeline is provided with an internal threaded oil pipe joint. One end of the internal threaded oil pipe joint is screwed into the brake fluid outlet of the master cylinder to ensure that the joint is tightly connected to the outlet of the master cylinder to prevent leakage. The other end of the internal threaded oil pipe joint is connected to the high-pressure oil pipe, which provides a flow path for the brake fluid in the pipeline. The outlet end of the pipeline is provided with an external threaded oil pipe joint. It is screwed into the brake fluid outlet of the slave cylinder to ensure that the joint matches the external thread of the slave cylinder outlet to form a firm connection. The other end of the external threaded oil pipe joint is connected to the hydraulic oil pipe, thus forming a liquid flow path of the master cylinder-detection device-slave cylinder.
[0045] Optionally, in some embodiments, Figure 3 As shown, generating a clutch detection result based on at least one of the first pressure change value and the second pressure change value includes:
[0046] Calculating a first pressure change rate of the pipeline within a preset time period based on the first pressure change value;
[0047] In an optional embodiment, assuming that the preset time period is 30 seconds, the pressure gauge reading P1 at the beginning of the test is recorded as the starting pressure of the test, and the pressure gauge reading P2 after 30 seconds is recorded. The first pressure change value is the change from the pressure reading P1 at the beginning of the test to the pressure reading P2 at the end (i.e., P1-P2). The first pressure change rate is calculated by the first pressure change value, and the calculation method is: first pressure change rate = first pressure change value / pressure reading P1 at the beginning of the test*100%. The first pressure change rate reflects the degree of pressure drop of the system in a closed state.
[0048] Obtaining a first threshold value;
[0049] Through a large number of experimental tests to collect data, statistical analysis of pressure changes under different conditions is performed to determine a reasonable average value and standard deviation, based on which the first threshold is set. The first threshold is a standard set based on experience or testing to determine whether the pressure change is within an acceptable range.
[0050] In response to the first pressure change rate being less than a first threshold, it is determined that the clutch detection result is that the clutch pump body is qualified.
[0051] By comparing the first pressure change rate with the first threshold, if the first pressure change rate is less than the first threshold, the clutch detection result is determined to be that the clutch pump body is qualified, and the pressure change is within the normal range. For example: if P1 is 1.5MPa and P2 is 1.45MPa, then the first pressure change value is 0.05MPa, and the first pressure change rate = 0.05MPa / 1.5MPa*100%≈3.33%. Assuming that the first threshold is set to 5%, the first pressure change rate = 3.33%<5%, it can be determined that the sealing of the clutch pump body is qualified and there is no obvious pressure release and air leakage.
[0052] Optionally, in some embodiments, generating the clutch detection result based on at least one of the first pressure change value and the second pressure change value further includes:
[0053] In response to the first pressure change rate being greater than or equal to the first threshold, determining a second pressure change rate, the second pressure change rate being determined by a second pressure change value;
[0054] In this embodiment, assuming that the first threshold is set to 5%, the first pressure change rate = 6%> 5%. At this time, the sealing of the clutch pump body is unqualified, and there is a pressure release and air leakage phenomenon. The specific location of the air leakage needs to be further determined. At this time, the control valve switching mechanism is in a closed pipeline state, and the clutch pedal is controlled to remain in a stepped working state within a preset time period. The second pressure change value of the pipeline within the preset time period is detected by the pressure detection mechanism; assuming that the preset time period is 30 seconds, the pressure gauge reading P3 at the beginning of the detection is recorded as the starting pressure of the detection, and the pressure gauge reading P4 after 30 seconds is recorded. The second pressure change value is the change from the pressure reading P3 at the beginning of the detection to the pressure reading P4 at the end (i.e. P3-P4). The second pressure change rate is calculated by the second pressure change value, and the calculation method is: second pressure change rate = second pressure change value / pressure reading P3 at the beginning of the detection*100%.
[0055] Obtaining a second threshold value;
[0056] Through a large number of experimental tests to collect data, statistical analysis of pressure changes under different conditions is performed to determine a reasonable average value and standard deviation, based on which the second threshold is set. The second threshold is a standard set based on experience or testing to determine the precise location of the leak. The setting of the second threshold takes into account the normal wear of the pump body, environmental factors and measurement errors, which helps to distinguish between real faults and acceptable performance fluctuations.
[0057] determining whether the second pressure change rate is less than a second threshold;
[0058] If yes, determine that the clutch detection result is pressure loss and air leakage from the slave cylinder.
[0059] By comparing the second pressure change rate with the second threshold, if the second pressure change rate is less than the second threshold. For example: if P3 is 1.5MPa, P4 is 1.45MPa, then the first pressure change value is 0.05MPa, the second pressure change rate = 0.05MPa / 1.5MPa*100%≈3.33%, assuming that the second threshold is set to 5%, the second pressure change rate = 3.33%<5%, then it can be determined that the clutch detection result is that there is a pressure release and air leakage in the slave cylinder.
[0060] In this embodiment, during the detection process, once the second pressure change rate exceeds the preset second threshold, it can be immediately confirmed that the slave pump has a pressure relief and air leakage problem, without further complex testing or long-term observation. This greatly speeds up the speed of fault diagnosis and shortens the maintenance time, playing a key role in improving service quality and reducing customer waiting.
[0061] Optionally, in some embodiments, generating the clutch detection result based on at least one of the first pressure change value and the second pressure change value further includes:
[0062] When the second pressure change rate is greater than or equal to the second threshold, it is determined that the clutch detection result is pressure relief and air leakage of the master cylinder.
[0063] For example, assuming that the second threshold is set to 5%, and the second pressure change rate=6%>5%, it can be determined that the clutch detection result is that the master pump has a pressure relief and air leakage phenomenon.
[0064] In this embodiment, by determining whether the second pressure change rate is greater than or equal to the second threshold, maintenance personnel can quickly distinguish whether the clutch system problem is caused by a failure of the slave cylinder or the master cylinder. This helps to implement targeted maintenance strategies, avoids the waste of resources for comprehensive inspections, and reduces maintenance costs.
[0065] Optionally, the clutch pump body detection device includes a warning device, and the control method also includes: when the clutch detection result is one of the master pump pressure relief and air leakage and the slave pump pressure relief and air leakage, generating a control instruction, and controlling the warning device to be in a working state based on the control instruction.
[0066] When the clutch detection result is one of the master pump pressure relief and leakage or the slave pump pressure relief and leakage, that is, the first pressure change rate exceeds the preset first threshold, the warning device can prompt the operator through sound, light or warning information on the display screen, avoiding manual continuous observation of the pressure gauge and greatly improving the detection efficiency. The existence of the warning device simplifies the operation process. The operator no longer needs to continuously pay attention to and record the pressure gauge reading. He only needs to wait for the warning signal and then make corresponding judgments and operations based on the signal.
[0067] The embodiment of the present invention also provides a computer program product, including a computer program, which implements the steps of the control method of the clutch pump body detection device in any of the above embodiments when the computer program is executed by a processor. The computer program also provides a user interface for displaying the pressure gauge reading and the fault diagnosis result to assist the technician in making a quick judgment.
[0068] An embodiment of the present invention further provides a computer-readable storage medium, which includes a stored program, wherein when the program is running, the device where the computer-readable storage medium is located is controlled to execute the control method of the clutch pump body detection device in any of the above embodiments.

[0072] Step S3: controlling the valve switching mechanism to be in a pipeline closing state, controlling the clutch pedal to remain in a stepped working state within a preset time period, and detecting a second pressure change value of the pipeline within the preset time period by the pressure detection mechanism;
[0073] Step S4: Generate a clutch detection result based on at least one of the first pressure change value and the second pressure change value, the clutch detection result including at least one of the following: the clutch pump body is qualified, the master pump is depressurized and leaking, and the slave pump is depressurized and leaking.
