Description

Technical Field

[0001] This invention relates to the field of automation control technology, and more specifically, to a method, apparatus, vehicle, and storage medium for testing the thermal safety of a vehicle. Background Technology

[0002] In the automotive technology field, especially for vehicles equipped with gasoline particulate filters (GPF), parking regeneration is a crucial step in maintaining the performance of the GPF and reducing particulate emissions, and its technical requirements are becoming increasingly stringent. In parking regeneration mode, by increasing the engine idle speed, adjusting the ignition timing and target air-fuel ratio, the particulate matter within the GPF is spurred to combust, thereby restoring the filter's filtration efficiency. However, this process is often accompanied by a significant increase in engine compartment temperature.

[0003] In relevant application scenarios, such as automotive maintenance service stations or user-operated parking regeneration, ensuring the safety of thermal management is indispensable. High temperatures not only affect the comfort of the cockpit but also pose a threat to heat-sensitive components in the engine compartment, such as electronic components, sensor harnesses, and decorative covers. Although these components are designed with a certain thermal safety margin, conventional thermal hazard assessment conditions and testing methods cannot fully cover the extreme temperature environment under parking regeneration conditions.

[0004] There is a lack of a complete and unified testing method in the current technology to accurately assess and control the risk of thermal damage to components inside the engine compartment during parking regeneration. Existing methods often focus on the regeneration efficiency of the gasoline engine particulate filter while neglecting the temperature protection of heat-sensitive components. As a result, in actual parking regeneration operations, these components may be subjected to high temperatures exceeding their temperature resistance range, thereby affecting their functional stability and even overall safety.

[0005] Therefore, there is an urgent need for a test method that can effectively identify and control the over-temperature problem of heat-sensitive components to make up for the shortcomings of existing technologies. Summary of the Invention

[0037] Figure 1 This is a flowchart of a vehicle thermal safety test method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0038] Step S102: Conduct a safety status test on the target vehicle and obtain the test results.

[0039] Optionally, the execution subject in this embodiment is the vehicle testing system. It should be noted that other electronic devices and processors can also be used as the execution subject, and no further limitations are made here.

[0040] In the technical solution provided by step S102 of the present invention, the test system first needs to confirm that the target vehicle has no external damage and that all systems and functions (such as engine, air conditioning system, fan control system, gasoline particulate filter (GPF), parking regeneration control program, etc.) are in normal working condition.

[0041] Furthermore, the integrity of temperature measurement points on heat source components and sensitive components must be checked. Heat source equipment includes turbochargers, various heat shields, etc., while sensitive component equipment includes high-temperature sensor harnesses, oxygen sensor harnesses, etc. By confirming whether these key components are equipped with temperature sensors and whether the sensors are working properly, it is possible to ensure that the temperature changes of each component can be accurately monitored during the test, thereby assessing the thermal safety status of the vehicle components.

[0042] In addition, the operating status of the fan needs to be checked, that is, by sending commands to the fan system to test whether it can respond to the changing duty cycle control signal, so as to ensure that the fan can adjust its speed as needed during the test.

[0043] Specifically, duty cycle refers to the ratio of the high-level time of a pulse signal within one cycle to the entire cycle time. In fan control systems, duty cycle determines the fan speed and heat dissipation efficiency.

[0044] Furthermore, a compatibility check of the GPF parking regeneration control program is required, i.e., verifying whether the vehicle's software system can correctly control the GPF parking regeneration process. By connecting diagnostic equipment, the GPF parking regeneration mode is activated to check whether the software commands are executed, ensuring precise control of GPF regeneration during the test and achieving the test objectives.

[0045] As an optional implementation method, when performing the above-mentioned safety condition tests on the vehicle, each test should be completed one by one, and detailed data should be recorded, such as the maximum and minimum fan speeds, as a basis for subsequent analysis. If any functional abnormality is found during the inspection, such as the fan failing to adjust its speed properly, the test should be stopped immediately and repaired to ensure that all systems are in a safe condition before the test begins.

[0046] As an alternative implementation, an automated testing process is employed. Through an integrated on-board diagnostic system interface, the status of various vehicle systems, including exterior damage reports and system self-test reports, is automatically read and compared with preset safety standards, and the test results are automatically output. This approach reduces human error and improves testing efficiency and accuracy.

[0047] It is worth noting that step S102 ensures that all systems of the vehicle are functioning properly before the test, and that there are no potential safety hazards. Through integrity checks and compatibility tests, it can prevent accidents during the test and ensure the authenticity and validity of the test data. Furthermore, this technical step helps to identify and resolve potential vehicle problems in advance, reducing unnecessary interruptions during the test and improving overall test efficiency and safety.

[0048] Step S104: In response to the detection result indicating that the target vehicle is in a safe test condition, the test parameters of the target vehicle are acquired.

[0049] In the technical solution provided by step S104 of the present invention, once the target vehicle is confirmed to be in a safe state, the test system begins to initialize the required test parameters, including but not limited to ambient temperature, engine idle speed, simulated GPF carbon combustion amount, GPF core temperature setpoint, fan duty cycle parameters and parking regeneration duration. These parameters are automatically read or manually input through a preset program to ensure that the test conditions are consistent and controllable.

[0050] Specifically, the test system can set the temperature of the high-temperature environment chamber within the range of 30-35℃, and continuously monitor the ambient temperature through temperature sensors to ensure that the temperature remains stable within the predetermined range throughout the entire test, providing a test condition that is close to the real environment.

[0051] Specifically, initial temperature readings are obtained from temperature sensors on confirmed heat source and sensitive components to serve as the basis for subsequent comparisons, so as to accurately assess temperature changes and thermal safety performance during the test.

[0052] As an alternative implementation method, on-board diagnostic equipment can be used to communicate directly with the vehicle's electronic control unit to automatically read and set the parameters required for the test, such as idle speed and GPF core temperature, while monitoring the ambient temperature. This method can automatically acquire and set parameters through the vehicle's own electronic system, which is efficient and accurate.

[0053] As another alternative implementation method, test parameters can be manually entered using a separate test console, such as setting the temperature of the environmental chamber and specifying the simulated value of carbon combustion. At the same time, the monitoring function of the console can be used to observe the temperature changes of the heat source and sensitive components in real time, ensuring that the test conditions meet the design requirements. This method is suitable for environments without automated test parameter setting capabilities, and ensures the consistency and safety of the test through manual intervention.

[0054] It is worth noting that step S104 ensures that the experiment is conducted under correct conditions. Through parameter initialization, ambient temperature setting and monitoring, and acquisition of data from heat sources and sensitive component measuring points, the experimenter can accurately control the experimental environment and conditions, thereby obtaining more reliable and effective test results. At the same time, this technical step also avoids experimental failures or data deviations caused by improper parameter settings, ensuring the success rate and quality of the experiment.

[0055] Step S106: Perform a parking regeneration thermal safety test on the target vehicle according to the test parameters to obtain multiple temperature values ​​of multiple test components. Each test component corresponds to a temperature value, and the multiple test components include heat source components and heat-sensitive components.

[0056] In the technical solution provided in step S106 of the present invention, the test system executes preset test parameters, such as adjusting the ambient chamber temperature to 30-35℃, setting the simulated GPF carbon combustion value, controlling the engine idle speed to 3000 r / min, setting the core temperature range of the GPF model, and controlling the fan duty cycle to ≥70%, to ensure that the test conditions meet the requirements. Furthermore, according to the set parameters, the test vehicle is controlled by a computer program to enter the parking regeneration mode. Simultaneously, the temperature changes of heat source components (such as turbochargers and three-way catalytic converters) and heat-sensitive components (such as high-temperature sensor harnesses and oxygen sensor harnesses) are continuously monitored to ensure accurate data acquisition. Then, temperature data during the test is recorded using a data acquisition module; the temperature value of each test component is recorded individually, facilitating subsequent specific analysis of different components.

[0057] As an alternative implementation, an integrated test control and data acquisition system is used. This system can automatically execute preset test parameters while monitoring and recording the temperature of all test components. This approach is suitable for highly automated test environments and can improve test efficiency and data accuracy.

[0058] It is worth noting that by conducting a parking regeneration thermal safety test and collecting temperature values ​​from various test components, this step directly obtains temperature data for heat source and heat-sensitive components under specific operating conditions, providing a basis for subsequent analysis. This data reflects the temperature distribution within the engine compartment and the heating status of heat-sensitive components during GPF parking regeneration, thereby assessing the overall vehicle's thermal safety performance under parking regeneration conditions. This technical step ensures the objectivity and validity of the test results, facilitates the identification of potential thermal damage risks, and provides a scientific basis for component design, material selection, and thermal management strategy optimization.

[0059] Step S108: Compare multiple temperature values ​​with multiple temperature thresholds to obtain a first comparison result, wherein the multiple temperature values ​​and multiple temperature thresholds correspond one-to-one.

[0060] In the technical solution provided in step S108 of the present invention, the temperature values ​​of multiple test components recorded during the experiment are imported into analysis software or a database to ensure the integrity and accuracy of the data, preparing for subsequent comparative analysis. Based on vehicle design requirements and material temperature resistance characteristics, a corresponding temperature threshold is set for each test component. Furthermore, the actual temperature value of each test component is compared one-to-one with the corresponding temperature threshold to determine whether the temperatures of multiple test components exceed the safe range.

[0061] Optionally, the temperature threshold represents the maximum permissible operating temperature set for the heat source component and the heat-sensitive component, used to determine whether it is safe under test conditions, i.e., exceeding this value may cause performance degradation or damage to the component.

[0062] As an alternative implementation method, professional data analysis software, such as MATLAB or Python scripts, can be used to automatically import experimental data and preset temperature thresholds, perform data comparisons, and output the first comparison result. This method is simple to operate, provides fast and accurate results, and is suitable for large-scale data processing.

[0063] It is worth noting that by comparing multiple temperature values ​​with multiple temperature thresholds to obtain the first comparison result, it is possible to directly determine whether the thermal safety performance of each component meets the standards during the test. This technical step, through objective data analysis, can quickly identify potential overheating issues, providing a direct basis for subsequent component optimization design, material improvement, or thermal management strategy adjustments, thus ensuring the thermal safety and reliability of the vehicle under parking regeneration conditions.

[0064] Step S110: In response to the first comparison result showing that multiple temperature values ​​are all less than multiple temperature thresholds, the test results of the thermal safety test are output.

[0065] In the technical solution provided by step S110 of the present invention, if all temperature values ​​in the first comparison result are lower than the corresponding temperature threshold, it indicates that the thermal management during the test is effective and there is no risk of thermal damage. Based on this analysis result, the test system will automatically generate a test report, which will list in detail the temperature change curve, final temperature value, and comparison with the threshold for each test component, thereby intuitively displaying the results of the thermal safety test.

[0066] As an alternative implementation method, automated data analysis software, such as MATLAB or a custom Python script, can be used. After configuring the temperature threshold, the software can automatically determine whether the temperature value is safe and automatically generate a detailed test result report. This method is suitable for environments that require rapid feedback of large amounts of data, reducing the time and error of manual analysis.

[0067] As an alternative implementation method, a manual inspection and report writing approach is adopted. By reading the data records, the temperature values ​​and thresholds of each test component are compared one by one to ensure that all temperatures are within the safe range. Then, the test results are generated manually or using a simple report template.

[0068] It is worth noting that step S110 ensures the effectiveness and integrity of the thermal safety test. It not only proves that the test method is successful in ensuring thermal safety during the GPF parking regeneration process, but also provides clear evidence for technicians by outputting detailed test results, confirming that the thermal management strategy of the vehicle design is adequate and effective.

[0069] Steps S102 to S110 above show that, in this invention, a test safety status detection is performed on the target vehicle to obtain a detection result. In response to the detection result indicating that the target vehicle is in a test safety state, test parameters of the target vehicle are obtained. Based on the test parameters, a thermal safety test for parking regeneration is performed on the target vehicle to obtain multiple temperature values ​​of multiple test components. Each test component corresponds to a temperature value. The multiple test components include heat source components and heat-sensitive components. The multiple temperature values ​​are compared with multiple temperature thresholds to obtain a first comparison result. The multiple temperature values ​​and multiple temperature thresholds correspond one-to-one. This achieves the technical effect of outputting the test result of the thermal safety test in response to the first comparison result indicating that the multiple temperature values ​​are all less than the multiple temperature thresholds. This can solve the technical problem in the prior art where a large amount of heat is generated during vehicle parking regeneration, leading to the risk of thermal damage to components inside the vehicle compartment.

[0070] The method described in this embodiment will now be described in further detail.

[0071] Step S1021: Detect multiple temperature measuring points, fan status, and gasoline engine particulate filter status of the target vehicle to obtain the detection results.

[0072] In this embodiment, the test safety status detection of the target vehicle includes detecting the temperature measurement points on multiple heat source components and heat-sensitive components, detecting the operating status of the fan, and detecting the status of the gasoline engine particulate filter.

[0073] Specifically, temperature measurement points refer to temperature sensors installed on different heat source components and heat-sensitive components of a vehicle to monitor and record temperature changes of these components.

[0074] Specifically, fan status refers to the operating status of the fan, including whether it can respond to control signals normally and whether the fan speed is controllable.

[0075] Specifically, GPF status refers to the working status of the gasoline engine particulate filter, including the normal operation of its control software, the connectivity of the hardware interface, and whether the filter's parking regeneration function can be effectively executed.

[0076] Specifically, check whether all the temperature measurement points of the set heat source components and heat-sensitive components on the vehicle are working properly. This includes confirming whether the sensors are connected, whether they can read data, and whether the data is within a reasonable range.

[0077] Specifically, to verify whether the target vehicle's fan control system can respond to different control signals, such as adjusting the fan speed to the maximum duty cycle, can be done by issuing specific control commands and observing the actual response of the fan, ensuring that the fan can operate effectively and perform necessary heat dissipation in high-temperature environments.

[0078] Specifically, the test confirms whether the relevant control software, hardware interfaces, and functions of the GPF are normal to ensure that the GPF can perform parking regeneration according to the preset parameters. Furthermore, the test also includes interface testing at the software level and verifying through actual operation whether the GPF parking regeneration can start and run smoothly.

[0079] As an optional implementation, an integrated vehicle diagnostic system or dedicated pre-test inspection software can be used to automatically execute the above-mentioned testing process, record the data of each temperature measuring point, the response status of the fan, and the status of the GPF control software, and finally generate a comprehensive test report to confirm whether the vehicle is in a safe testing condition.

[0080] It is worth noting that by separately checking multiple temperature measurement points, fan status, and GPF status of the target vehicle, it is possible to ensure that the status of each system of the vehicle meets safety standards before the test begins. This effectively prevents potential equipment failures or safety issues during the test, ensuring the accuracy and completeness of the test. Simultaneously, this technical step can help identify potential vehicle problems, such as temperature measurement point failures, fan control issues, or GPF malfunctions, facilitating vehicle maintenance and improvement.

[0081] Step S1041: Obtain the ambient temperature value of the target vehicle;

[0082] Step S1042: Determine the test environment temperature value based on the external ambient temperature value.

[0083] In this embodiment, a temperature sensor is used to measure the temperature of the current environment in which the vehicle is located. This step can be achieved by measuring the current external temperature value using a sensor installed on the outside of the vehicle or by using a handheld device during the test preparation phase. Based on the acquired external ambient temperature value, the temperature to be set in the test environment chamber can be determined.

[0084] Specifically, this technical step involves adjusting the temperature to simulate specific usage scenarios, such as performance evaluation of vehicles under high summer temperatures or low winter temperatures, to ensure that the test conditions reflect real-world usage environments.

[0085] As an optional implementation method, the automatic control system and temperature sensor in the environmental chamber can read the external ambient temperature value before the test begins, and then adjust the temperature of the environmental chamber according to the preset logic or algorithm to simulate a specific environment. For example, if the external ambient temperature is 25°C, the test environment will be automatically adjusted to 30-35°C to ensure that the particulate matter in the trap can be effectively burned during the test, while not deviating from the actual ambient temperature range.

[0086] As an alternative implementation, in the absence of an automatic control system, the test personnel can manually read the ambient temperature and set the temperature of the environmental chamber according to the test requirements. This implementation may require frequent checks and fine-tuning to ensure that the temperature of the environmental chamber remains stable within the set range. For example, if the ambient temperature is 20°C, the test personnel can manually set the environmental chamber temperature to 30°C and continuously monitor it during the test to ensure temperature stability.

[0087] It is worth noting that by acquiring the ambient temperature value and determining the test environment temperature accordingly, it is possible to ensure that the environmental conditions of the thermal safety test match the actual operating environment of the vehicle. This not only improves the reliability of the test results but also allows for a more accurate assessment of the vehicle's thermal safety performance under different environmental conditions. Furthermore, this technical step also helps reduce test errors, ensures the consistency and repeatability of test conditions, thereby improving test efficiency and data quality.

[0088] Step S1043: Obtain the carbon load of the gasoline engine particulate filter;

[0089] Step S1044: Determine the carbon combustion amount of the gasoline engine particulate filter based on the carbon load;

[0090] Step S1045: Determine the target carbon combustion temperature value based on the amount of carbon burned.

[0091] In this embodiment, the test system needs to measure the amount of carbon particles accumulated in the gasoline engine particulate filter (GPF). This can be determined by analyzing the pressure loss of the GPF or by estimating it using specialized software based on vehicle operating data. Based on the carbon load of the GPF, the amount of carbon particles that need to be burned in the test is calculated. Furthermore, based on the determined amount of carbon burned, the minimum temperature required to achieve complete carbon combustion, i.e., the target carbon combustion temperature, is calculated.

[0092] Specifically, carbon loading is the amount of unburned carbon particles accumulated in the GPF, and it is an important parameter that determines the regeneration frequency and regeneration effect of the GPF.

[0093] Specifically, carbon combustion is the amount of carbon particles that are planned to be burned during the GPF parking regeneration test, used to evaluate the GPF regeneration efficiency.

[0094] Optionally, the target carbon combustion temperature of the GPF model can generally be controlled within the range of 720 to 790°C. This temperature ensures that the carbon in the particulate filter burns intensely without generating excessive heat that could cause thermal damage to components in the cabin.

[0095] As an optional implementation, an integrated vehicle diagnostic system and GPF regeneration software are used. The vehicle diagnostic system can automatically read the carbon load of the GPF, and the GPF regeneration software can automatically calculate the amount of carbon to be burned and the corresponding carbon combustion temperature value according to the preset regeneration efficiency target.

[0096] It is worth noting that by obtaining the carbon load of the gasoline engine particulate filter, determining the carbon combustion rate and the target carbon combustion temperature, this step can ensure that the parameter settings of the GPF parking regeneration test match the actual operating conditions of the vehicle. This not only improves the effectiveness of the test, but also enables precise control of the carbon combustion process, avoids unnecessary energy waste and potential heat damage risks, and ensures the safe conduct of the test while evaluating and optimizing the GPF regeneration efficiency and thermal management strategy.

[0097] Step S1046: Obtain the objective function image, wherein the objective function image is used to show the relationship between the fan duty cycle and the carbon combustion temperature value;

[0098] Step S1047: Determine the target fan duty cycle corresponding to the target carbon combustion temperature value based on the objective function graph.

[0099] In this embodiment, the experimental system first needs to construct a graph depicting the mathematical relationship between the fan duty cycle (as a response variable) and the internal carbon combustion temperature of the GPF (as a control variable). This preset graph can reflect the influence of fan power on the GPF regeneration temperature. The point corresponding to the target carbon combustion temperature value is found in the objective function graph, thereby determining the fan duty cycle to be set in the experiment.

[0100] Specifically, the control fan operates according to the target fan duty cycle to ensure that cooler outside air is drawn into the engine compartment for forced convection. This disperses the high-temperature heat source radiation and convection heating caused by GPF parking regeneration, reducing the surface temperature of sensitive components in the engine compartment and minimizing the risk of heat damage.

[0101] As an optional implementation, automated analysis is performed using computer software. During the test preparation phase, the objective function graph is imported into the software, which automatically identifies the target carbon combustion temperature value and calculates the corresponding optimal fan duty cycle using an image analysis algorithm.

[0102] It is worth noting that by acquiring the objective function image and determining the target fan duty cycle based on the image, this technical step enables precise control of the fan power during the GPF parking regeneration test. This ensures that while achieving the target carbon combustion temperature, the risk of thermal damage to components inside the engine compartment is minimized, balancing the requirements of efficient GPF regeneration and component safety. This technical step improves the reliability and efficiency of the test, reduces the uncertainty of the test results, and provides a solid foundation for subsequent test analysis and the design of the vehicle thermal management system.

[0103] Step S1101: In response to the comparison results showing that multiple temperature values ​​are all less than multiple temperature thresholds, the target vehicle is controlled to idle for a preset time period.

[0104] Step S1102: In response to the target vehicle ending its idling operation, detect the cabin temperature value of the target vehicle.

[0105] Step S1103: Compare the cabin temperature value with the preset temperature value to obtain a second comparison result;

[0106] Step S1104: In response to the second comparison result indicating that the cabin temperature is less than the preset temperature value, the test result of the thermal safety test is output.

[0107] In this embodiment, after completing the GPF parking regeneration test, the final temperature values ​​of all heat-sensitive components are collected and compared with a preset temperature threshold to confirm that the temperature of all monitored components has not exceeded the safety limit, ensuring that no risk of heat damage occurs during the test. Furthermore, if the first comparison result indicates that the temperature values ​​are all safe, the system will automatically or manually control the target vehicle to enter an idling state for a period of time to allow the temperature inside the engine compartment to drop naturally. After the idling operation ends, the overall temperature of the vehicle compartment is immediately measured and recorded to assess the temperature state of the engine compartment after heat dissipation. The collected vehicle compartment temperature value is then compared with a preset safe temperature value after cooling to determine whether the vehicle compartment temperature has dropped to a safe level after the idling operation.

[0108] Specifically, when the cabin temperature is detected to be lower than the preset temperature, it indicates that the GPF parking regeneration and subsequent cooling processes have not caused excessive heat load on the cabin. The test results will be officially recorded to confirm the effectiveness of the thermal safety management strategy.

[0109] Specifically, the aforementioned preset time period is a fixed duration for idling operation, used to ensure adequate cooling time for the vehicle after GPF parking regeneration, and is generally set to 10 minutes.

[0110] As an optional implementation, the above steps are automatically executed through an integrated vehicle diagnostic and control system, from temperature data acquisition and temperature value comparison to idle speed operation control, and then to cabin temperature value acquisition and final comparison result output. The entire process requires no manual intervention, ensuring the continuity of data and the timeliness of results.

[0111] It is worth noting that this technical step ensures that the thermal safety test not only monitors the temperature of heat-sensitive components during GPF parking regeneration, but also confirms the thermal stability of the entire vehicle by controlling idle speed and detecting cabin temperature after regeneration. This closed-loop monitoring and verification mechanism improves the comprehensiveness of the test and the reliability of the results, avoids thermal management problems that may be missed due to monitoring a single temperature point, and provides strong data support for the design and optimization of vehicle thermal management systems.

[0112] Step S112: In response to the first comparison result indicating that at least one temperature value among the multiple temperature values ​​is greater than the temperature threshold corresponding to at least one temperature value, the target test component corresponding to at least one temperature value is determined.

[0113] Step S114: Generate a test report based on the component information of the target test component, wherein the test report includes: the optimization strategy of the target test component.

[0114] In this embodiment, after completing the GPF parking regeneration test, the final temperature values ​​of all monitoring points are collected and compared with preset temperature thresholds. If the temperature value of any of the multiple test components exceeds the corresponding temperature threshold, the overheated test component is marked as a target test component. Furthermore, based on the first comparison result, all test components with temperature values ​​exceeding the temperature threshold are identified, i.e., test components that may be at risk of heat damage during the GPF parking regeneration process are identified.

[0115] Specifically, based on detailed information about the target test component, including component type, location, material, and actual temperature value during the test, a test report is generated. The report will include analysis of each overheated component and recommended optimization strategies, aiming to reduce the risk of heat damage and improve the thermal safety performance of the component.

[0116] As an optional implementation, the temperature data and the first comparison results of the test are transmitted to the automated analysis software in real time. The analysis software will automatically identify the overheated components and generate a test report based on the component information database and preset optimization rules. The report contains detailed optimization strategies and suggestions.

[0117] It is worth noting that the above steps ensure that when thermal management problems are discovered, there are clear directions for improvement and specific measures, which directly contribute to improving the thermal safety and reliability of vehicles under extreme operating conditions. By generating test reports that include optimization strategies, test personnel and design engineers can quickly understand the problem, providing guidance for subsequent design and development work, avoiding potential thermal damage issues, and ensuring the thermal safety performance of vehicles during parking regeneration.
