[0001] This application relates to the field of vehicle control technology, and more specifically, to a method, apparatus, processor, and electronic device for adjusting equipment in a vehicle. Background Technology

[0002] Currently, the mainstream flow resistance testing methods in vehicles rely on manual operation. For example, testers roughly control the flow rate by manually adjusting bypass valves or water pump frequency converters. After the flow rate and differential pressure readings stabilize, the values ​​of the flow meter and differential pressure sensor are manually recorded, and then the valve opening is manually adjusted. The above process is repeated point by point to obtain multiple sets of flow rate-differential pressure data.

[0003] To achieve measurement coverage across different operating conditions, repeated manual intervention is required, and the stability assessment at each point relies on the operator's experience, resulting in slow system response and long operating condition switching cycles. Therefore, the technical problem of low adjustment efficiency for equipment in vehicles still exists.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to an embodiment of this application, an embodiment of a method for adjusting equipment in a vehicle is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] Figure 1 This is a flowchart of a method for adjusting equipment in a vehicle according to an embodiment of this application, such as... Figure 1 As shown, the method may include the following steps.

[0030] Step S102: Detect the current pressure information of the device to be tested in the vehicle.

[0031] In the technical solution provided by step S102 of this application, the current pressure information can be used to represent the pressure difference between the two ends of the device under test at the current time.

[0032] In this embodiment, during the operation of the fluid circulation system in the vehicle, the instantaneous pressure difference across the device under test (e.g., a radiator, water valve, piping assembly, or a specific flow resistance component in the thermal management module) is collected and acquired in real time, allowing the detection of current pressure information. This current pressure information can be the pressure difference (ΔP_current). The device under test can also be referred to as the device under test.

[0033] Optionally, the aforementioned current pressure information is not a pressure reading at a single location, but rather the result of measuring the absolute pressure of the fluid before and after it flows through the device under test using two high-precision pressure sensors placed at the inlet and outlet of the device under test. The difference between the two pressures is then calculated in real time by a differential pressure calculation unit (integrated in a programmable logic controller or data acquisition card), thereby obtaining a direct physical quantity characterizing the device under test's ability to impede fluid flow, namely the current pressure information ΔP_current.

[0034] Optionally, the above detection process can be implemented using a parameter measurement system. For example, in a fluid circulation loop, two pressure sensors are precisely installed at the upstream and downstream interfaces of the device under test, ensuring that the measurement points are close to the device body to avoid errors introduced by pipeline disturbances or local eddies. The pressure sensor signals are continuously transmitted to the programmable logic controller (PLC) via a high sampling rate data acquisition card. The PLC reads and calculates the current pressure information at fixed intervals (e.g., 10ms to 100ms), and simultaneously compensates for and corrects the fluid density and viscosity by combining real-time data from the temperature sensor, ensuring the physical accuracy of the current pressure information.

[0035] In this embodiment, by detecting the current pressure information of the device under test in the vehicle, a real, continuous, and high-precision feedback signal is provided for subsequent closed-loop control, enabling the vehicle's control system to accurately determine whether the current flow resistance state has approached the target pressure information. This provides accurate information for determining the adjustment strategy of the device under test.

[0036] Step S104: Based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, determine the adjustment strategy of the device under test.

[0037] In the technical solution provided in step S104 of this application, the target pressure information can be used to represent the constant pressure difference established at both ends of the device under test. The target error information can be used to represent the allowable range of deviation between the current pressure information and the target pressure information. The adjustment strategy can be used to represent the rules for adjusting the fluid flow rate in the device under test, where the current pressure information and the fluid flow rate (e.g., flow rate) are positively correlated.

[0038] In this embodiment, the target pressure information can be the target differential pressure value (ΔP_target). The target error information can be the allowable error range ε.

[0039] Optionally, in actual operation, the target pressure information can be a pre-set expected pressure difference value by the operator or the test procedure, representing the steady-state resistance level that the equipment under test should reach under a specific operating condition. For example, setting the target pressure information to 50 kPa means simulating the typical operating pressure difference that the equipment under test may withstand in the vehicle's cooling system.

[0040] Optionally, the aforementioned target error information can be an acceptable deviation range set to adapt to actual control system fluctuations, such as ±1.5 kPa, to determine whether the control system has entered a stable state and to avoid frequent misadjustments of the control system due to minor vibrations of various sensors or fluid disturbances.

[0041] Optionally, the current pressure information can be obtained in real time from the front and rear pressure sensors, representing the actual pressure difference currently experienced by the device under test.

[0042] Optionally, the determination of the adjustment strategy relies on the dynamic evaluation of the difference between the current pressure information and the target pressure information. Under the operating conditions of a vehicle's cooling system, the fluid flow rate and the current pressure information exhibit a clear monotonically increasing nonlinear functional relationship. That is, the larger the fluid flow rate, the higher the current pressure information (e.g., pressure drop) caused by the fluid flowing through the device under test, and this relationship follows a power law or quadratic polynomial trend. Therefore, the control system does not need to rely on complex models; a simple and efficient proportional-integral-derivative (PID) control algorithm can achieve a fast response.

[0043] Optionally, when the current pressure is detected to be lower than the target pressure, the control system determines that the fluid flow rate needs to be increased to improve resistance. Therefore, it can send an acceleration command to the pump (e.g., a variable frequency pump) or widen the opening of the regulating valve (e.g., an electric regulating valve). When the current pressure is detected to be higher than the target pressure, the system can reduce the pump speed or decrease the opening of the regulating valve to reduce the fluid flow rate, thereby lowering the current pressure.

[0044] Optionally, the entire adjustment process described above can use the target error information as the convergence criterion. If the difference between the current pressure information and the target pressure information is less than or equal to the target error information, the adjustment action is terminated and the process enters the data recording stage.

[0045] Optionally, the process of determining the above-mentioned adjustment strategy can be executed in real time by the control program inside the Programmable Logic Controller (PLC) or industrial computer without manual intervention.

[0046] In this embodiment, based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, the adjustment strategy of the device under test is determined, which can achieve accurate, automatic, and stable maintenance of the flow resistance test condition, replacing the inefficient and high-error operation mode of manually adjusting valves, waiting for readings to stabilize, and manually recording data.

[0047] Step S106: Adjust the device to be tested according to the adjustment strategy.

[0048] In the technical solution of step S106 of this application, adjusting the device under test according to the adjustment strategy means that in the automatic flow resistance test system of the vehicle, based on the deviation between the current pressure difference information collected in the previous stage and the preset target pressure difference information, the control system automatically executes closed-loop adjustment action. By adjusting the flow output in the fluid circulation loop, the current pressure difference information, that is, the pressure difference between the two ends of the device under test, gradually approaches and stabilizes at the target pressure difference information (e.g., the target value).

[0049] In this embodiment, the above-mentioned adjustment strategy is not a simple open-loop control, but rather a system based on a PID control algorithm, combined with real-time feedback signals to dynamically generate control commands, thereby achieving high-precision and high-response-speed automated adjustment.

[0050] Optionally, the control system can calculate the required fluid flow adjustment based on the difference between the current differential pressure information ΔP_current and the target differential pressure information ΔP_target, and convert this instruction into a control signal. If the current differential pressure information is higher than the target differential pressure information, it indicates that the fluid resistance is too high or the fluid flow rate is too high. In this case, the PLC can send a frequency reduction instruction to the frequency converter to reduce the speed of the main circulating water pump, thereby reducing the total fluid flow rate. If the current differential pressure information is lower than the target differential pressure information, the pump speed can be increased to increase the fluid flow rate.

[0051] Alternatively, fine control of local flow resistance can be achieved by adjusting the opening of an electric regulating valve installed in the bypass or main circuit.

[0052] Optionally, by adjusting the equipment under test according to the adjustment strategy, dynamic approximation testing of the flow resistance characteristics of the equipment under test can be achieved, so that the data acquisition of each test point is based on a stable, controllable and reproducible operating condition.

[0053] In this embodiment, precise dynamic adjustment reduces subjective errors and response delays caused by manual operation, resulting in highly consistent and repeatable test results. By automatically completing continuous scanning at multiple operating points without human intervention, it enables rapid plotting of flow resistance characteristic curves across the entire flow range, from low to high fluid flow rates. The adjustment process is adaptive, capable of handling characteristic fluctuations in the tested components due to batch differences, temperature drift, or changes in fluid viscosity, ensuring the authenticity and engineering applicability of the test results. The entire adjustment process is completed in a closed, unattended environment, significantly reducing personal safety risks under high-pressure and high-temperature conditions. Therefore, this adjustment strategy not only automates and intelligentizes the testing process but also provides a technological foundation for efficient, high-precision, and high-safety testing in the development of cooling system components.

[0054] In steps S102 to S106 of this application, if adjustment of the device under test is required, the current pressure information of the device under test in the vehicle can be detected. The current pressure information represents the pressure difference between the two ends of the device under test at the current time. Based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, an adjustment strategy for the device under test can be determined. The target pressure information represents the constant pressure difference established between the two ends of the device under test, the target error information represents the allowable range of deviation between the current pressure information and the target pressure information, and the adjustment strategy represents the rules for adjusting the fluid flow rate in the device under test. The current pressure information and the fluid flow rate are positively correlated. The device under test can be adjusted according to the adjustment strategy. In other words, this application embodiment accurately senses the current pressure information, i.e., the pressure difference between the two ends of the device under test at the current time. Then, combined with the preset target pressure information and allowable error range, a fluid flow rate adjustment strategy conforming to physical laws can be dynamically generated, achieving high-precision, adaptive control of the fluid flow rate. Without human intervention, it automatically completes the adjustment of the equipment under test under multiple working conditions, thereby solving the technical problem of low adjustment efficiency of equipment in vehicles and achieving the technical effect of improving the adjustment efficiency of equipment in vehicles.

[0055] The method described in this embodiment will be further described below.

[0056] As an optional embodiment, step S104, based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, determines the adjustment strategy of the device under test, including: determining the pressure information difference between the current pressure information and the target pressure information; and determining the adjustment strategy of the device under test based on the pressure information difference and the target error information.

[0057] In this embodiment, during the process of determining the adjustment strategy of the device under test based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, the pressure information difference between the current pressure information and the target pressure information can be calculated, and the adjustment direction and intensity to be adopted can be determined according to the relative relationship between the pressure information difference and the target error information, thereby determining a simple, efficient, and physically meaningful adjustment strategy.

[0058] Optionally, the pressure information difference mentioned above can be the absolute difference between the current pressure information and the target pressure information.

[0059] Optionally, the above target error information can be set based on sensor accuracy, fluid dynamic fluctuation characteristics, and acceptable error thresholds for engineering testing.

[0060] Optionally, the determination of the adjustment strategy does not rely on complex model predictions or multivariate optimization, but can be based on a simple yet efficient second-order judgment logic. For example, when |ΔP_current - ΔP_target| ≤ ε, it can be determined that the system has entered a steady state, requiring no adjustment, and the system enters the data recording stage. When |ΔP_current - ΔP_target| > ε, it is determined that the current pressure information is too high, and the fluid flow rate can be reduced to lower the resistance. When |ΔP_current - ΔP_target| < – ε, it is determined that the current pressure information is too low, and the fluid flow rate can be increased to increase the resistance.

[0061] Optionally, the above adjustment strategy achieves a rapid response mechanism of over-adjustment to reverse and under-adjustment to forward through proportional judgment, which is suitable for fluid systems with known flow resistance characteristics and good response characteristics.

[0062] In this embodiment, the adjustment strategy for the device under test is determined based on the pressure information difference and target error information. This allows the entire process from significant deviation to stable convergence to be completed within 3–5 seconds, significantly better than the several minutes of waiting time required for manual operation. Furthermore, because the control logic is transparent, traceable, and highly resistant to interference, overshoot or oscillations caused by integral accumulation errors or differential spikes are avoided. This ensures that data acquisition at each test point is in a precise steady state, greatly improving the repeatability and reliability of the test data.

[0063] As an optional embodiment, the device under test includes: a water pump and / or a regulating valve, wherein the water pump is used to provide power to the fluid circulation system in the vehicle, and the regulating valve is used to perform local throttling regulation of the fluid passage of the fluid circulation system. Based on the pressure information difference and target error information, a regulation strategy for the device under test is determined, including: in response to the pressure information difference being greater than the target error information and the pressure information difference being greater than the information difference threshold, determining the regulation strategy for the device under test as a first regulation strategy, wherein the first regulation strategy is used to reduce the speed of the water pump or reduce the opening of the regulating valve; in response to the pressure information difference being greater than the target error information and the pressure information difference being less than or equal to the information difference threshold, determining the regulation strategy for the device under test as a second regulation strategy, wherein the second regulation strategy is used to increase the speed of the water pump or increase the opening of the regulating valve.

[0064] In this embodiment, by introducing an information difference threshold, the system can dynamically select different adjustment priorities and execution methods based on the deviation of the current pressure information from the target pressure information, thereby ensuring control accuracy while taking into account the system response speed and stability.

[0065] Optionally, the device under test can be a water pump, a regulating valve, or a combination of both. The water pump, as the system's power source, can globally regulate the fluid flow rate throughout the entire circulation loop by changing its speed. The regulating valve (e.g., an electrically operated regulating valve) can act as a local throttling element, applying controllable resistance to a specific pipe section by changing the valve's opening, thus achieving precise control of the current pressure information.

[0066] Optionally, in actual testing, if the device under test is a water pump, then the water pump itself is the component whose flow resistance is being measured, and adjusting the speed directly changes the operating characteristics. If the device under test is a regulating valve, then the flow rate through the regulating valve needs to be indirectly controlled by changing the speed of the water pump or the opening of another regulating valve, thereby measuring the flow resistance characteristics.

[0067] Optionally, the pressure information difference can be calculated and compared with two key thresholds. The first is the target error information, used to determine whether the system has entered a stable, permissible range. The second is the information difference threshold, an intermediate value greater than the target error information, used to distinguish between "severe deviation" and "slight deviation" adjustment scenarios.

[0068] Optionally, when the pressure information difference is greater than the target error information, and the absolute value of the pressure information difference is greater than the information difference threshold, it can be determined that the current pressure information deviates significantly from the target pressure information. In this case, the first adjustment strategy can be selected. For example, the pump speed can be reduced or the opening of the regulating valve can be closed first to achieve a rapid and significant reduction in fluid flow, thereby quickly reducing the excessively high pressure difference. The first adjustment strategy is suitable for severe disturbances at the beginning of the test or after the target is switched. By actively reducing the speed of the power source, the pressure difference surge can be quickly contained, avoiding system overpressure or oscillation, and improving the coarse adjustment efficiency of the response.

[0069] Optionally, when the pressure information difference is greater than the target error information but less than or equal to the information difference threshold, it can be determined that the current pressure information is only slightly deviating. In this case, a second adjustment strategy is adopted. For example, the pump speed can be appropriately increased or the opening of the regulating valve can be increased to gently increase the fluid flow rate and gradually raise the current pressure information to the current pressure information. The second adjustment strategy avoids over-adjustment caused by system inertia and is especially suitable for smooth transitions between test points or fine control of low-flow-rate, high-sensitivity test devices (such as miniature throttle valves), ensuring a stable, smooth, and shock-free control process.

[0070] Optionally, the determination logic of the above adjustment strategy can be determined by PLC or host computer control software based on the real-time collected differential pressure data and preset thresholds, without relying on manual intervention and executed completely automatically.

[0071] In this embodiment, the above steps significantly shorten the stabilization time of the test points, especially in high-flow-rate sections, reducing the adjustment cycle from tens of seconds to several seconds. This reduces system pressure fluctuations or fluid shocks caused by overly aggressive adjustments, extending the service life of the equipment under test. It also enhances compatibility with different types of equipment under test (e.g., high-inertia water pumps, low-resistance regulating valves).

[0072] As an optional embodiment, the method further includes: in response to the pressure information difference being less than or equal to the target error information, invoking the data acquisition module to record the current pressure information and the pressure information difference, and obtaining the recording result; and generating report information based on the recording result.

[0073] In this embodiment, when the control system confirms that the pressure information difference is less than or equal to the target error information, that is, the deviation between the current pressure difference and the target pressure difference has fallen within the preset tolerance range (i.e., |ΔP_current-ΔP_target|≤ε), it indicates that the device under test is in a stable working state. At this time, the fluid flow parameters (e.g., fluid flow rate, pressure difference, temperature) no longer fluctuate significantly, and the system determines that the data collected under this operating condition has engineering validity. Therefore, the controller can automatically activate the data acquisition module, which can consist of a high-precision data acquisition card and a real-time storage program. This module synchronously reads and records the current pressure difference value, the corresponding flow rate value (provided in real-time by the flow meter), the fluid temperature (used for density compensation), the sampling timestamp, and the pressure information difference value during this adjustment process. This data not only serves as the original record for this test point but is also structured and stored in a local database for subsequent processing.

[0074] Optionally, after data recording is complete, the report generation module can be automatically invoked. Based on a preset template, it integrates information such as the differential pressure-flow rate pair, test condition number, ambient temperature, and equipment number of the current test point into structured data, and automatically plots the coordinate position of that point on the flow resistance characteristic curve. Simultaneously, multiple sets of test points are plotted consecutively to form a complete and smooth flow resistance characteristic curve, ultimately outputting a standardized test report in PDF format. The report includes key information such as test time, operator, equipment model, target parameters, measured data, and curve fitting coefficients, meeting multiple needs for R&D, quality control, and archiving.

[0075] In this embodiment, the device under test can be connected according to the cooling system principle. The power cord is connected to the sample, and the communication line is connected to the Controller Area Network (CAN) device. The water pump signal transmission and reception are monitored, and the water pump duty cycle is controlled after confirming that there are no problems. Pressure sensors are placed at both ends of the device under test and connected to the data acquisition box. The data acquisition box channels are set up to measure the pressure of the device under test. Before the test begins, coolant is added to the cooling system through the expansion tank, the water pump speed is adjusted, and the air in the water pump is fully expelled through the venting device. The venting status of the cooling system is observed, the liquid level in the expansion tank is kept at the maximum liquid level line, and the venting time of the cooling system is recorded.

[0076] As an optional embodiment, the method further includes: setting an initial fluid flow rate value for the vehicle, wherein the initial fluid flow rate value is used to represent a reference value for the initial fluid flow rate of the fluid circulation system in the vehicle; obtaining a current fluid flow rate value applied to the device under test under the initial fluid flow rate value; and detecting the current pressure information of the device under test in the vehicle, including: detecting the device under test based on the current fluid flow rate value to obtain the current pressure information.

[0077] In this embodiment, an initial fluid flow rate value can be set as the starting point reference for the entire test sequence. This initial fluid flow rate value can be simply referred to as the initial flow rate value. The initial flow rate value can be based on the typical operating range of the device under test, past testing experience, or a conservative safety starting point preset by the system design. For example, it can be set to 5 L / min to ensure that the flow rate is within a safe range that is not extreme, cavitation-free, or overpressured when the system starts up, preventing the device under test (e.g., radiator, throttle valve, pipeline) from being subjected to instantaneous impact due to the sudden application of a high flow rate, which could cause structural damage or measurement distortion.

[0078] Optionally, after recording the cooling system exhaust time, system initialization can be performed, setting the initial flow rate value and the target pressure difference value. The water pump is driven to apply the current fluid flow rate value (e.g., current flow rate), the current pressure information (e.g., pressure difference) is automatically measured, and it is determined whether the pressure difference is stable at the target pressure information (e.g., target value).

[0079] In this embodiment, traditional manual testing often involves operators gradually increasing the fluid flow rate from zero, requiring several minutes to stabilize after each adjustment. This is not only inefficient but also prone to data distortion due to insufficient system venting, residual air bubbles, or incomplete sensor warm-up. In contrast, this embodiment employs a standardized process of explicitly setting an initial fluid flow rate value, forcibly confirming fluid flow rate stability, and then triggering pressure acquisition. This ensures that every test starts from the same physical state, significantly improving test repeatability and data consistency.

[0080] As an optional embodiment, the method further includes: adjusting the current fluid flow rate value; detecting the device under test in response to the adjusted current fluid flow rate value to obtain current pressure information; and stopping the detection of the device under test in response to the current pressure information being the same as the target pressure information.

[0081] In this embodiment, the control system can automatically modify the speed of the main circulation pump or the opening of the regulating valve according to a preset test strategy. For example, it can automatically modify the speed of the main circulation pump or the opening of the regulating valve in a fixed step (e.g., increasing by 1 L / min each time) or in a logarithmic increment, thereby precisely changing the flow rate of the fluid flowing through the device under test.

[0082] Optionally, after each fluid flow rate adjustment, the current pressure information is not immediately collected; instead, the system waits for the fluid system to reach a new steady state. This waiting period can be monitored in real-time by the control system to track flow and pressure fluctuations. When the flow rate fluctuation is less than a set threshold (e.g., ±0.5%) and the pressure reading shows no significant change for three consecutive frames, it can be determined that the new operating condition has stabilized. The pressure sensor array is then triggered to simultaneously collect the pressure at the inlet and outlet of the device under test, calculating the current pressure information, i.e., the new current pressure information. Subsequently, this new current pressure information is compared with the pre-set target pressure information.

[0083] Optionally, when the difference between the current pressure information and the target pressure information at a certain test point is less than or equal to the preset target error information (e.g., ±1.0 kPa), it can be determined that the target working condition has been successfully achieved. Then, further adjustment and testing of the working condition is stopped, and the fluid flow adjustment process for the next target point is entered until each preset target point is completed.

[0084] In this embodiment, pressure difference changes are actively driven by fluid flow rate adjustment, with the target pressure information as the endpoint guide, to achieve a reverse closed-loop test of pressure-driven flow. This differs from the traditional forward test that measures pressure difference at fixed flow points one by one. This embodiment uses the target pressure information as navigation coordinates to automatically find the fluid flow rate required to achieve the target pressure information, and finally directly plots the complete characteristic curve of pressure difference-flow rate, which is closer to the operating logic of pressure difference determining flow rate distribution in the actual vehicle thermal management system.

[0085] As an optional embodiment, the method further includes: invoking a data processing module to fit the current pressure information and the current fluid flow rate applied to the device under test to generate a flow resistance characteristic curve of the device under test. The data processing module is deployed in the vehicle's data processing and interaction system, and the flow resistance characteristic curve is used to characterize the variation law of flow resistance of the device under test under different fluid flow rate conditions.

[0086] In this embodiment, after completing the automatic adjustment and pressure-flow data acquisition at multiple operating points, the data processing module deployed in the vehicle data processing and interaction system can be automatically invoked to systematically fit the recorded current fluid flow rate value and the corresponding current pressure information, thereby generating the flow resistance characteristic curve of the device under test. This curve, with flow rate as the horizontal axis and pressure difference as the vertical axis, intuitively presents the variation law of flow resistance of the device under test under different flow conditions.

[0087] Optionally, by calculating the absolute difference between the current pressure information and the target pressure information, if it is greater than the target error information, PID feedback regulation is initiated. If the pressure difference is too high, the flow rate can be automatically reduced until the system stabilizes at the target pressure difference. After traversing the test points and completing the measurement, the software automatically sets the target flow rate to the current fluid flow rate value, repeating the above steps until the measurement of each operating point is completed. After each test point is completed, the control software automatically calls the data processing module to plot the flow resistance characteristic curve with flow rate Q as the abscissa and pressure drop as the ordinate, and exports it as a PDF test report.

[0088] Optionally, the data processing module does not simply connect the sampling points linearly. Instead, based on engineering experience and fluid dynamics models, it uses a nonlinear fitting algorithm to smoothly reconstruct the discrete data points. The processing includes: data denoising, outlier removal, unit unification, temperature compensation correction (adjusting fluid viscosity based on temperature sensor data), and curve fitting goodness evaluation, ensuring that the final output flow resistance characteristic curve conforms to physical laws and is representative of engineering applications. The fitted flow resistance characteristic curve not only includes the original sampling points but also provides continuous mathematical expressions, supporting pressure difference interpolation calculations at various intermediate fluid flow rates, greatly improving data usability.

[0089] In this embodiment, if adjustment of the device under test is required, the current pressure information of the device under test in the vehicle can be detected. The current pressure information represents the pressure difference between the two ends of the device under test at the current time. Based on the current pressure information, the target pressure information of the device under test, and the target error information of the device under test, an adjustment strategy for the device under test can be determined. The target pressure information represents the constant pressure difference established between the two ends of the device under test, the target error information represents the allowable range of deviation between the current pressure information and the target pressure information, and the adjustment strategy represents the rules for adjusting the fluid flow rate in the device under test. The current pressure information and the fluid flow rate are positively correlated. The device under test can be adjusted according to the adjustment strategy. In other words, this embodiment accurately senses the current pressure information, i.e., the pressure difference between the two ends of the device under test at the current time. Then, combined with the preset target pressure information and allowable error range, a fluid flow rate adjustment strategy conforming to physical laws can be dynamically generated, achieving high-precision, adaptive control of the fluid flow rate. Without human intervention, it automatically completes the adjustment of the equipment under test under multiple working conditions, thereby solving the technical problem of low adjustment efficiency of equipment in vehicles and achieving the technical effect of improving the adjustment efficiency of equipment in vehicles.

[0090] The technical solutions of the embodiments of this application will be illustrated below with reference to preferred embodiments.

[0091] Currently, the role of automotive cooling systems is to maintain the vehicle within an appropriate operating temperature range under various conditions, preventing damage caused by overheating or overcooling of the power source and ensuring optimal vehicle operation. As a crucial component of the automotive system, it directly impacts the vehicle's ability to function properly. With the rapid development of the automotive industry, automotive component products are constantly being optimized and updated, significantly increasing the difficulty of early component design and selection. Process testing is necessary to determine the cooling performance of selected components. During the design and selection phase, it is essential to understand the process characteristics of each component and use process curves to verify the correctness of the component cooling design. Process issues in product development are often resolved through experimental testing. On one hand, bench test data is needed to support computational simulations, analyzing system performance integration and matching. On the other hand, bench testing is also required to verify the consistency of product design and the quality consistency of components within the same batch.

[0092] In bench testing, the flow data of the selected components is crucial. Flow curves allow for analysis of the system's matching performance data. Measured values ​​of flow rate and pressure are required for the flow performance tests of the selected components. Due to the diversity of products in the initial system selection process, the preparation for bench testing is time-consuming and costly. Therefore, the versatility of the selected components should be considered during testing. This allows for rapid verification of the selected components' performance, enabling them to have universal testing capabilities, thereby reducing testing costs and improving testing efficiency.

[0093] In related technologies, traditional flow resistance measurement methods often employ manual adjustment. A typical operation involves roughly adjusting the flow rate or pressure using manual valves. Once the readings stabilize, the values ​​from the flow meter and differential pressure gauge are manually recorded. Then, the valve opening is adjusted and the water pump is controlled to proceed to the next measurement point. This method has several drawbacks. For example, it is inefficient, requiring manual intervention and waiting for the system to stabilize at each test point, which is time-consuming and labor-intensive. It suffers from poor accuracy, as manual adjustment struggles to precisely achieve and maintain the target operating conditions (e.g., constant flow rate or constant differential pressure), readings are subject to subjective errors, and the judgment of system stability relies on human experience, leading to large data dispersion. Repeatability is poor; tests performed by different operators or by the same operator at different times yield inconsistent results. It has limited functionality, making it difficult to implement complex testing procedures such as continuous scanning and dynamic characteristic testing. Safety is also a concern, as manual operation poses certain risks in high-pressure or high-temperature testing environments.

[0094] In addition, while there have been some attempts at automation in related technologies, most of them focus on the automation of data acquisition. However, there is still a lack of efficient and accurate closed-loop control strategies in the core process of operating condition adjustment. The system integration is not high, which cannot meet the urgent needs of modern industry for high-precision and high-efficiency testing.

[0095] To address the aforementioned issues, this application proposes a highly automated, highly accurate, repeatable, and safe fully automatic test apparatus and method for adjusting and measuring flow resistance. It eliminates the need for repeated manual valve adjustments, improving efficiency and accuracy. Through a closed-loop control algorithm, it can quickly approach and stabilize at the target pressure difference, reducing human error and reading errors. Highly consistent results can be obtained under the same test conditions, demonstrating excellent repeatability.

[0114] Figure 3 This is a flowchart of an automatic adjustment test method according to an embodiment of this application, such as... Figure 3 As shown, the steps include the following.

[0115] Step S301, system initialization.

[0116] In this embodiment, an initial test flow rate (Q_initial), a target differential pressure (ΔP_target), and an allowable error range ε ​​can be set.

[0117] Step S302: Apply the current flow rate and measure the real-time differential pressure.

[0118] In this embodiment, the control system (e.g., a variable frequency pump or a precision valve) applies the currently calculated flow rate (Q_current) to the device under test. The pressure difference (ΔP_current) across the device under test is measured in real time using a high-precision pressure sensor.

[0119] Step S303: Determine whether the pressure difference is stable at the target value.

[0120] In this embodiment, the absolute difference between the current differential pressure and the target differential pressure is calculated, and it is determined whether this difference is less than or equal to the allowable error value (ε). If so, the system reaches a steady state, and the flow rate (Q_current) and differential pressure (ΔP_current) at this time are recorded, completing one measurement. The target differential pressure value can be changed, and the process is repeated for the next set of tests. If not, the system enters PID feedback regulation. If the differential pressure is too high, the system will automatically reduce the flow rate; if the differential pressure is too low, the system will automatically increase the flow rate. After the system adjusts the flow rate, a new flow rate is applied, and the measurement and judgment are repeated, forming a closed-loop PID control loop until the system stabilizes at the target differential pressure. After each test point is completed, a flow resistance characteristic curve is automatically generated.

[0121] Step S304: Record the flow rate and pressure difference at this time.

[0122] In this embodiment, if the pressure difference stabilizes at the target value, the flow rate and pressure difference at this time are recorded.

[0123] In step S305, the system automatically increases or decreases the flow rate.

[0124] In this embodiment, if the pressure difference does not stabilize at the target value, the control system automatically increases or decreases the flow rate.

[0125] Figure 4 This is a flowchart of a test method according to an embodiment of this application, such as... Figure 4 As shown, the steps include the following.

[0126] Step S401, Device connection and startup.

[0127] In this embodiment, the test sample can be connected according to the cooling system principle. The power cord is connected to the sample, and the communication line is connected to the CAN device. The water pump signal transmission and reception are monitored, and the water pump duty cycle is controlled after confirming that there are no problems. Pressure sensors are placed at both ends of the test sample and connected to the data acquisition box. The data acquisition box channels are set up to measure the sample pressure.

[0128] Step S402: Exhaust air from the cooling system.

[0129] In this embodiment, before the test begins, coolant is added to the cooling system through the expansion tank, the water pump speed is adjusted, the air in the water system is fully discharged through the venting device, the venting status of the cooling system is observed, the liquid level in the expansion tank is kept at the maximum liquid level line, and the venting time of the cooling system is recorded.

[0130] Step S403, automatic adjustment and measurement.

[0131] In this embodiment, the system initializes by setting an initial flow rate and a target differential pressure. The pump is driven to apply the current flow rate, and the real-time differential pressure is automatically measured to determine if it is stable at the target value. The absolute difference between the current and target differential pressures is calculated. If it exceeds the allowable error value, the system enters PID feedback regulation. If the differential pressure is too high, the system automatically reduces the flow rate until it stabilizes at the target differential pressure. The system iterates through the test points. After completing measurement Q1, the software automatically sets the target flow rate to Q2. The above steps are repeated until all operating point measurements are completed.

[0132] Step S404: Data recording and report generation.

[0133] In this embodiment, after all test points are completed, the control software automatically calls the data processing module to plot the flow resistance characteristic curve with flow rate Q as the x-axis and pressure drop as the y-axis, and exports it as a PDF test report.
