[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] According to an embodiment of the present application, a method embodiment of a vehicle controller testing method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] In this embodiment, a method for testing a vehicle controller is provided. Figure 1 FIG. 1 is a flow chart of a method for testing a vehicle controller according to an embodiment of the present application, as shown in FIG. Figure 1 As shown, the process includes the following steps:

[0038] Step S102: obtaining first configuration parameters of a controller to be tested on a vehicle.

[0039] The first configuration parameter may refer to a parameter that can reflect the physical layout of the controller to be tested, such as the installation position, installation details, installation environment, and other parameters of the controller to be tested on the vehicle.

[0040] In an alternative embodiment of the present invention, considering that the stable operation of controllers on a vehicle, such as an engine control unit, airbag controller, electronic stability program controller, etc., has a decisive impact on the safe driving of the vehicle and the driving experience of the user, it is particularly important to test the controllers on the vehicle in multiple aspects, such as environmental adaptability, functional consistency, and dynamic performance evaluation, to determine the stability and accuracy of the controllers under test during vehicle driving. Furthermore, considering the differences in the first configuration parameters of the controllers under test, the factors that may affect the operation of the controllers under test may be different. For example, the controller in the engine compartment may be subject to more frequent temperature changes, higher vibration levels, and greater power loads than the controller in the passenger compartment, while the radar controller located at the rear of the vehicle may be subject to erosion by moisture and dust, and vibration caused by bumpy roads. Therefore, in order to accurately test the controllers under test, the test system can first identify the controllers under test to obtain the first configuration parameters of the controllers under test, and then accurately determine the factors that may affect the operation of the controllers under test based on the first configuration parameters, so that the test system can accurately test the controllers under test based on the determined factors.

[0041] Step S104: Based on the first configuration parameter, a plurality of test factors matching the controller to be tested are obtained from the factor mapping relationship table.

[0042] The factor mapping relationship table is used to store the mapping relationship between the first configuration parameter and the test factor, and the test factor is used to represent the factors that will affect the operation process of the controller to be tested in the driving environment of the vehicle.

[0043] In an optional solution of this embodiment, considering that in the driving environment of the vehicle, there are usually many environmental stresses that will affect the operation process of the controller to be tested, such as temperature, humidity, vibration, electromagnetic interference, chemical corrosion and other stresses, and most of the environmental stresses are unavoidable during the driving process of the vehicle, therefore, in the process of testing the controller to be tested, the factors that need to be clearly considered that will affect the operation process of the controller to be tested can include these environmental stresses. Since the degree to which different environmental stresses affect the operation process of the controller to be tested is different under different first configuration parameters, in order to avoid the blindness that may occur in the process of testing the controller to be tested, the test system can select multiple environmental stresses that will have a significant impact on the operation process of the controller to be tested as multiple test factors for testing the controller to be tested. In order to improve the efficiency of determining multiple test factors, a factor mapping relationship table for storing the mapping relationship between the first configuration parameters and the test factors can be configured in the test system, so as to record and analyze the first configuration parameters of different controllers, such as installation location, physical layout, connection method and other parameters, and the interaction rules between different environmental stresses through the factor mapping relationship table. Correspondingly, when obtaining multiple test factors, the test system can quickly select from the factor mapping relationship table multiple environmental stresses that match the controller to be tested and have a significant impact on the operation process of the controller to be tested based on the first configuration parameters of the controller to be tested, as multiple test factors for testing the controller to be tested, thereby avoiding the application of irrelevant factors to the test process, resulting in waste of resources and the generation of misleading test results.

[0044] Step S106: Combine multiple test factors according to a preset combination strategy to construct at least one test factor group.

[0045] In an alternative solution to this embodiment, considering that the environmental stresses to which a vehicle controller is subjected may vary under different driving environments, the impacts on the vehicle controller under different environmental stresses may also vary. For example, the aging rates of circuit boards and components may differ at temperatures of 100°C and 50°C, and the degree of corrosion of circuits and connectors may differ in high-concentration salt spray and low-concentration salt spray scenarios. Therefore, to test the operation of the controller under test when the vehicle is driving under different driving environments, the testing system may generate a factor combination including at least one test factor based on the obtained multiple test factors in a preset manner, such as permutation and combination, random selection, etc., such as a factor combination including only test factors such as temperature or humidity, or a factor combination including both test factors such as temperature and humidity. The system then assigns values ​​to different factors in the factor combination, such as assigning a preset temperature value to the temperature in the factor combination and a preset humidity value to the humidity, thereby constructing at least one test factor group. The at least one test factor group is then used to test the controller under test, thereby ensuring comprehensive testing of the controller under test.

[0046] Step S108: Using a test device, test the controller to be tested based on at least one set of test factor groups to obtain a controller test result.

[0047] The controller test results are used to characterize the operation status of the controller to be tested during the test process.

[0048] In an optional scheme of this embodiment, in order to simulate the real operating scenario and ensure the effectiveness and credibility of the test of the controller to be tested, the test system can use test equipment, such as an environmental simulation chamber, a vibration table, impact test equipment, etc., to test the controller to be tested based on at least one set of test factor groups constructed, so as to obtain accurate controller test results, so as to use the controller test results to reflect the operating status of the controller to be tested during the test process.

[0049] In an embodiment of the present application, a method is adopted in which a first configuration parameter of a controller to be tested on a vehicle is obtained; based on the first configuration parameter, a plurality of test factors matching the controller to be tested is obtained from a factor mapping relationship table; the plurality of test factors are combined according to a preset combination strategy to construct at least one test factor group; and a test device is used to test the controller to be tested based on at least one test factor group to obtain a controller test result. By determining a plurality of test factors that will have a greater impact on the operation process of the controller to be tested according to the first configuration parameter, and then using at least one test factor group constructed from the plurality of test factors to test the controller to be tested, the comprehensiveness of the test of the controller to be tested can be ensured while avoiding the intervention of test factors that are irrelevant to or have a low impact on the operation process of the controller to be tested, which affects the accuracy of the controller test results, thereby achieving the purpose of fine-grained testing of the controller to be tested, thereby achieving the technical effect of reducing costs and shortening test cycles while ensuring test accuracy, thereby solving the technical problem of poor accuracy in testing controllers on vehicles in related technologies.

[0050] Furthermore, the test equipment includes: a vehicle and an initial test bench; using the test equipment, testing the controller to be tested based on at least one set of test factor groups to obtain a controller test result, including: configuring the initial test bench based on at least one set of test factor groups to obtain a target test bench; according to a preset test strategy, using the vehicle and the target test bench in turn to perform collaborative testing on the controller to be tested to obtain collaborative test data of the controller to be tested; determining the controller test result based on the collaborative test data and calibrated controller data.

[0051] In an optional solution of this embodiment, considering that the vehicle is a highly complex and interdependent system, in order to ensure the stability and safety of the vehicle during actual driving, the test system needs to consider not only the controller performance that the controller on the vehicle can exhibit under the influence of different test factors, but also the ability of different controllers to interact and work together on the vehicle. However, due to the high complexity of the vehicle itself and the vehicle driving environment, when the controller to be tested is tested separately through a simple environmental simulation, it is usually impossible to reflect the interaction and collaboration between different controllers. Therefore, in the actual process of testing the controller to be tested, the test collaboration can introduce the vehicle in which the controller to be tested is expected to be deployed, that is, use the vehicle as the above-mentioned test equipment to test the controller to be tested, so as to use the performance of the controller to be tested during the vehicle driving process to reflect the interaction and collaboration between the controller to be tested and other controllers. Furthermore, due to the large variety of vehicle driving environments, it is difficult to fully determine the operating conditions of the controller to be tested under different driving environments simply by the vehicle driving method. Therefore, in addition to using the vehicle as a test device to test the controller to be tested, one or more initial test benches can also be configured in the test device to use the initial test bench to simulate the driving environment that the controller to be tested may face based on at least one set of test factor groups constructed above.

[0052] Based on this, when using the test equipment to test the controller to be tested, the test system can first use the constructed at least one set of test factor groups to configure the initial test bench to obtain the target test bench, and then according to the preset test strategy, use the vehicle and the target test bench in turn to perform collaborative testing on the controller to be tested, obtain corresponding collaborative test data, and use the collaborative test data and calibration controller data, that is, the operating data of the controller to be tested under ideal conditions, to construct corresponding controller test results, so as to use the controller test results to accurately reflect the operating conditions of the controller to be tested. For example, the test system can first test the controller to be tested on the vehicle, then install the controller to be tested on the target test bench for testing, and finally redeploy the controller to be tested on the vehicle for testing, so as to form a closed-loop test process, ensuring that the state changes from the original state of the controller to the state after being tested in extreme environments are fully recorded and evaluated, thereby testing the controller's recovery ability and long-term reliability in a real-world use environment.

[0053] Furthermore, the preset test strategy includes: a first test strategy corresponding to the vehicle, and a second test strategy corresponding to the target test bench; according to the preset test strategy, the vehicle and the target test bench are used in turn to perform collaborative testing on the controller to be tested to obtain collaborative test data of the controller to be tested, including: based on the vehicle, performing a functional test on the controller to be tested according to the first test strategy to obtain first functional test data of the controller to be tested, wherein the first functional test data is used to characterize the operating status of the controller to be tested when the vehicle is operating normally; disassembling the controller to be tested from the vehicle, and based on the target test bench, performing a factor test on the disassembled controller to be tested according to the second test strategy to obtain factor test data, wherein the factor test data is used to characterize the operating status of the controller to be tested under the action of at least one group of test factor groups; reinstalling the controller to be tested to the vehicle, and re-based on the vehicle, performing a functional test on the controller to be tested according to the first test strategy to obtain second functional test data of the controller to be tested; obtaining collaborative test data based on the first functional test data, the factor test data, and the second functional test data.

[0054] In an optional solution of this embodiment, in order to stably utilize the vehicle and the target test bench to perform collaborative testing on the controller to be tested, the preset test strategy used may at least include: a first test strategy used when the vehicle is used to test the controller to be tested, and a second test strategy used when the target test bench is used to test the controller to be tested. When performing collaborative testing on the controller to be tested, the test system may first install the controller to be tested on the vehicle and control the vehicle operation according to the first test strategy, such as controlling the vehicle to travel at a preset speed, controlling the vehicle to travel under a preset environment, etc., to perform a functional test on the controller to be tested, thereby obtaining first functional test data of the controller to be tested, so as to use the first functional test data to reflect the operating conditions of the controller to be tested when the vehicle is driving normally, such as whether the controller to be tested is operating normally, whether it is interacting normally with other controllers, etc. After using the vehicle to perform a functional test on the controller to be tested, the test system can disassemble the controller to be tested from the vehicle and install it on the target test bench, and use the target test bench to perform factor testing on the controller to be tested according to the second test strategy, such as changing the factor values ​​of different test factors configured on the target test bench in real time, or performing a long-term test on the controller to be tested on the target test bench, etc., to obtain corresponding factor test data, and use the factor test data to determine the operating conditions of the controller to be tested under the influence of the above-mentioned at least one group of test factors, thereby accurately determining the adaptability of the controller to be tested in different driving environments. After using the target test bench to test the controller to be tested, the test system can reinstall the controller to be tested on the vehicle and retest the controller to be tested according to the first test strategy to obtain corresponding second functional test data to determine whether the controller to be tested can continue to operate on the vehicle after being affected by at least one test factor. Correspondingly, based on the above-mentioned first functional test data, second functional test data and factor test data, the above-mentioned collaborative test data can be constructed.

[0055] Among them, when using the target test bench to test the controller to be tested, in order to improve the test efficiency, the test system can use different test benches to test different controllers at the same time. Take the deployment of bench 1 and bench 2 as an example, as shown in the following table:

[0056] Table 1

[0057]

[0058] In bench 1, the test system can test controller combinations of categories A1 and A2. The corresponding test conditions may include: muddy water, dust, and windshield washer fluid, a temperature range of -40 to 110°C, a humidity range of 30% RH to 90% RH (for example, 90% RH), and vibration and shock. In bench 2, the test system can test controller combinations of categories B2, B2, B2, B3, D1, D2, D3, and D4. The corresponding test conditions may include: muddy water, dust, a temperature range of -40 to 110°C, a humidity range of 90% RH, vibration and shock, and sunlight simulation.

[0059] The test results obtained by using bench 1 and bench 2 to test the controller to be tested can be respectively as follows Figure 2 and Figure 3 As shown, taking the life of the controller to be tested at different temperatures as an example, Figure 2 is a schematic diagram of a bench test stress coupling according to an embodiment of the present application. Figure 3 FIG. 1 is a schematic diagram of another bench test stress coupling according to an embodiment of the present application. Specifically, Figure 2 As shown, with temperature, humidity, vibration and other stresses as test stresses, the test controller can be tested for 1 hour at 23°C and preset vibration conditions in the first test time period; in the second test time period, the controller to be tested is tested for 4 hours at 60°C, 90% RH and preset vibration conditions; in the third test time period, the controller to be tested is tested for 8 hours at -10°C and preset vibration conditions; in the fourth test time period, the controller to be tested is tested for 8 hours only at 110°C; in the fifth test time period, the controller to be tested is tested for 8 hours at 23°C and preset vibration conditions; in the sixth test time period, the controller to be tested is tested for 5 hours only at -40°C; in the seventh test time period, the controller to be tested is tested for 8 hours only at -40°C; in the eighth test time period, the controller to be tested is tested for 7 hours at 23°C and preset vibration conditions.

[0060] like Figure 3As shown, with stresses such as temperature, humidity, vibration, and sunlight as test stresses, the test system can test the controller to be tested at 23°C for 1 hour in the first test time period; in the second test time period, the controller to be tested is tested at 85°C for 8 hours, and sunlight is introduced as an irradiation condition in the last 2 hours of this time period to test the controller to be tested; in the third test time period, the controller to be tested is tested at 23°C and preset vibration conditions for 8 hours; in the fourth test time period, the controller to be tested is tested at 60°C, 90% RH and preset vibration conditions for 4 hours; in the fifth test time period, the controller to be tested is tested at -10°C and preset vibration conditions for 8 hours; in the sixth test time period, the controller to be tested is tested only at 85°C for 8 hours; in the seventh test time period, the controller to be tested is tested only at -40°C for 5 hours; and in the eighth test time period, the controller to be tested is tested at 23°C and preset vibration conditions for 7 hours.

[0061] pass Figure 2 and Figure 3 It can be seen from the content that when using a test bench to conduct system-level reliability testing on the controller to be tested on a vehicle, the test design can fully consider the dynamic changes of different stresses in the time dimension and the diversity of stress intensity. That is, the stress type and intensity applied in different time periods are not necessarily fixed, but can be carefully selected from the mapping relationship between environmental stress and failure mode based on the specific installation location and working environment of the controller. This allows test engineers to customize test plans according to the personalized needs of the controller, while also ensuring that the test system can automatically execute preset combined stresses to improve test efficiency, thereby achieving precise control of test conditions.

[0062] Furthermore, based on the vehicle, a functional test is performed on the controller to be tested according to the first test strategy to obtain first functional test data of the controller to be tested, including: controlling the vehicle to be stationary, and obtaining static test data generated by the controller to be tested when the vehicle is stationary; controlling the vehicle to travel according to a preset driving condition, and obtaining dynamic test data generated when the vehicle travels according to the preset driving condition; constructing the first functional test data based on the static test data and the dynamic test data.

[0063] In an optional scheme of this embodiment, in order to more comprehensively determine the operating conditions of the controller to be tested when the vehicle is running, when performing a functional test on the control to be tested, the test system can first control the vehicle to be stationary to obtain static test data generated by the controller to be tested when the vehicle is stationary, and then control the vehicle to travel according to preset operating conditions, for example, control the vehicle to travel at a preset speed and a preset driving path to obtain dynamic test data generated when the vehicle travels according to the preset driving conditions. Based on the static test data and the dynamic test data, the test system can construct corresponding first functional test data.

[0064] To facilitate understanding of controlling the vehicle to drive according to the preset driving conditions, Figure 4 is a schematic diagram of a preset driving condition according to an embodiment of the present application, such as Figure 4 As shown, the preset driving conditions used in the test system may include: serpentine conditions (used to test the Y-direction load of the controller). In the serpentine conditions, the test system can control the vehicle to drive according to the preset driving path, and also control the vehicle to brake urgently during driving to determine the operation of the controller to be tested when the vehicle drives on a complex driving path and brakes urgently. For example, the test system can drive 2 circles on a square right-angle turn path, then drive 3 circles forward and backward on an 8-shaped path, and finally drive a serpentine path at a speed of 60-65km / h, and repeat this back and forth 3 times to determine the operation of the controller under different driving paths. In addition, the preset driving conditions used in the test system may also include emergency braking conditions (used to test the X-direction load of the controller), bad road conditions (used to test the Z-direction load of the controller), etc. Among them, in the emergency braking condition, the test system can control the vehicle to travel in a preset direction, such as from east to west, at a speed of 100 km / h, and perform emergency braking three times in a row during the driving process to detect the operation of the controller to be tested under emergency braking; in the bad road condition, the test system can first drive through a twisting road at 30 km / h, then drive through a pothole road at 40 km / h, and then drive through a speed bump at 60 km / h. Then, after turning around, for example, after driving from west to east to the eastern boundary, turn around and drive through the speed bump at 60 km / h, then drive through a rope road at 25 km / h, then drive through a Brazilian stone road at 60 km / h, then turn around again after driving to the western area boundary, drive through a twisting road at 30 km / h, then drive through a pothole road at 40 km / h, then drive through the speed bump at 60 km / h, and finally drive out of this test section, so as to determine the operation of the controller under the bad road condition.

[0067]

[0068] For ease of understanding, Table 2 above shows the items that need to be checked for different controllers when the vehicle is stationary and in motion when the controller is tested using a vehicle. For example, for a discless navigation system, since the discless navigation system can provide navigation, entertainment, Bluetooth connection and other functions, the items that need to be checked when the vehicle is stationary may include: checking navigation map updates, Bluetooth connection stability, etc.; the items that need to be checked when the vehicle is in motion may include: Global Positioning System (GPS) signals, navigation route planning, etc.; during the test of the discless navigation system, the test system can also obtain the operating data of the interactive controller that interacts with the discless navigation system, such as the vehicle speed information output by the ECU, the temperature information displayed by the automatic air conditioning control module, and other data. In addition, the functional descriptions, stationary inspection items and driving inspection items of other controllers, as well as the relevant operating data of the corresponding interactive controllers, can be shown in Table 2 above and will not be repeated here.

[0069] Furthermore, based on the collaborative test data and the calibration controller data, the controller test result is determined, including: matching the first function test data with the calibration function data to obtain a first matching result, wherein the first matching result is used to characterize whether the first function test data is consistent with the calibration function data; matching the factor test data with the calibration factor data to obtain a second matching result, wherein the second matching result is used to characterize whether the factor test data is consistent with the calibration factor data; matching the first function test data with the second function test data to obtain a third matching result, wherein the third matching result is used to characterize whether the first function test data is consistent with the second function test data; constructing the controller test result based on the first matching result, the second matching result and the third matching result.

[0070] In an optional solution of this embodiment, when using collaborative test data and calibration controller data to determine the controller test results, the test system can first match the first functional test data with the calibration functional data to obtain a corresponding first matching result. Based on the first matching result, the test system can determine whether the two are consistent, thereby determining whether the current operation of the controller under test on the vehicle is stable and whether it can be put into use. Similar to matching the first functional test data with the calibration functional data, the test system can further match the factor test data with the calibration factor data to obtain a corresponding second matching result. Based on the second matching result, the test system can also determine whether the two are consistent, thereby determining the adaptability of the controller under test to different test factors and its stability under different test factors. Furthermore, unlike matching the first functional test data with the calibration functional test data, the test system can match the second functional test data with the first functional test data to determine whether the controller under test can maintain consistent performance and operate stably after being subjected to the different test factors. Finally, the determined first matching result, second matching result, and third matching result are sorted and summarized to obtain a controller test result that can reflect the operation status of the controller to be tested.

[0071] Furthermore, the initial test bench is configured based on at least one set of test factor groups to obtain a target test bench, including: identifying any set of test factor groups to obtain target factors contained in any set of test factor groups; assigning values ​​to the target factors according to a preset numerical strategy to obtain at least one set of target factor parameters; and configuring the initial test bench based on any set of target factor parameters to obtain a target test bench.

[0072] In an optional scheme of this embodiment, in order to accurately configure the initial test bench, the test system can first identify any group of test factor groups to determine the target factors that currently need to be configured on the initial test bench, and then assign values ​​to the determined target factors according to a preset numerical strategy, such as determining the factor values ​​contained in any group of test factor groups, or assigning values ​​in sequence according to preset numerical values, such as assigning values ​​to parameters such as the size of the target factor, the time period of the test, and the duration of the test, so as to obtain the above-mentioned at least one group of target factor parameters, and finally use this any group of target factor parameters to configure the target factors in the initial test bench, for example, within the test time period corresponding to the target factor, the initial test bench is configured according to the size of the determined target factor, so as to obtain the above-mentioned target test bench. Specifically, the target factors are assigned to obtain at least one group of target factor parameters, and the initial test bench is configured using any group of target factor parameters. Figure 2 and Figure 3, which will not be repeated here. Furthermore, the above method also includes: identifying the factor mapping relationship table to obtain controller identifiers of multiple vehicle controllers and environmental factor identifiers of multiple environmental factors, wherein the multiple vehicle controllers are used to characterize the controllers that need to be tested on the vehicle, and the multiple environmental factors are used to characterize the factors that will affect any vehicle controller; based on the controller identifiers, obtaining second configuration parameters of the multiple vehicle controllers, wherein the multiple vehicle controllers include the controller to be tested; based on the environmental factor identifiers, obtaining third configuration parameters of multiple factor simulation devices, wherein the multiple factor simulation devices are used to simulate multiple environmental factors; and building an initial test bench based on the second configuration parameters and the third configuration parameters.

[0073] In an optional scheme of this embodiment, in order to be able to configure different test factors on the initial test bench to conduct a comprehensive test of the controller to be tested, the test system can first identify the constructed factor mapping relationship table to determine the controller identifiers of multiple vehicle controllers that can be deployed on the vehicle, and the environmental factor identifiers of multiple environmental factors in the vehicle driving environment that may affect the operation of any vehicle controller. Based on the controller identifiers, the test system can first obtain second configuration parameters of these multiple vehicle controllers, such as installation location, installation method, auxiliary equipment required for installation, and other parameters, and use the environmental factor identifiers of these multiple environmental factors to obtain third configuration parameters of the factor simulation device used to simulate these multiple environmental factors. Based on the second configuration parameters and the third configuration parameters, the test system can construct an initial test bench that can test different vehicle controllers under different environmental factors.

[0074] Furthermore, the above method also includes: obtaining first configuration parameters of multiple vehicle controllers on the vehicle; dividing the vehicle based on the first configuration parameters of multiple vehicle controllers to obtain multiple controller areas; determining at least one environmental factor corresponding to any controller area based on the regional characteristics of any controller area; constructing a factor mapping relationship table based on the first configuration parameters of any controller area and at least one environmental factor corresponding to any controller area.

[0075] In an optional scheme of this embodiment, considering that the test factors that may affect the operation of the vehicle controller may be different under different first configuration parameters, in order to construct an accurate factor mapping relationship table, the test system can first obtain the first configuration parameters of multiple vehicle controllers on the vehicle, and use the first configuration parameters of these multiple vehicle controllers to divide the vehicle to obtain multiple controller areas, and then use the regional characteristics of any controller area to determine at least one environmental factor in the driving environment that will affect the vehicle controller in any one control area, and finally use the third configuration parameters of any one controller area and at least one environmental factor corresponding to any one controller area to construct the above-mentioned factor mapping relationship table.
