Description

Technical Field

[0001] The present invention relates to the technical field of vehicle window anti-pinch technology, and in particular to a calibration method, system, device, readable storage medium, and vehicle for a vehicle window anti-pinch function. Background Art

[0002] In order to meet the needs of drivers and passengers to frequently open and close the windows, such as when paying parking fees in a parking lot, passing through a toll booth, or communicating with others, the car windows are designed to be electric windows that can automatically rise and fall. Automatically rising and falling electric windows improve the user experience. At the same time, there are some potential safety hazards. For example, the automatic rising and falling function is unstable or fails, which may cause the window to clamp the passenger's hand or other objects.

[0003] In order to improve safety, the automatic lifting electric window has added a window anti-pinch function. The window anti-pinch function is that when the window is closed, if there is a person's hand, finger, or even a pet's body part, or other objects stuck on the window, the window anti-pinch function will immediately stop the window closing action to avoid injury. In order to test the stability of the window anti-pinch function, the related art provides a method for testing the anti-pinch function of the automobile window assembly. Before the vehicle is offline, the window assembly of the physical vehicle is tested for the anti-pinch function to improve the stability of the anti-pinch function before delivery. However, this test method needs to be tested on the physical vehicle. If the test fails, the window assembly and control system need to be reworked, which increases the testing cost and production cost. In addition, the entire test cycle is long, resulting in low test efficiency, which in turn affects the production efficiency of the entire vehicle. Summary of the invention

[0004] One of the purposes of the present invention is to provide a calibration method, system, device, readable storage medium, and vehicle for a vehicle window anti-pinch function, so as to improve the stability of the operation of the vehicle window anti-pinch function and reduce the testing cost of the vehicle window anti-pinch function.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] The present application proposes a calibration method for a vehicle window anti-pinch function, comprising: obtaining first operating data under a load operating state of a vehicle window assembly and second operating data under a target load applying state; obtaining a trigger threshold for triggering the vehicle window anti-pinch function according to the first operating data and the second operating data; in the process of performing dynamic calibration tests under different operating conditions, using an anti-pinch tester to detect the actual anti-pinch force when the vehicle window anti-pinch function is triggered; and dynamically correcting and testing the trigger threshold according to the actual anti-pinch force and the target anti-pinch force to obtain the target trigger threshold.

[0007] By adopting the calibration method of the window anti-pinch function provided by the present application, the accurate calibration of the triggering threshold of the anti-pinch function can be improved, thereby reducing the maintenance and adjustment caused by the inaccurate anti-pinch function, and reducing the initial testing cost and the later maintenance cost. In addition, the calibration method of the window anti-pinch function provided by the present application can complete the calibration of the window anti-pinch function under the window control simulation system constructed by software, and is also applicable to the calibration of the window anti-pinch function of the physical window assembly and the window controller. Compared with the physical vehicle test in the related art, the testing cost is reduced and the testing cycle is shortened. In addition, the calibration method of the window anti-pinch function provided by the present application can be used as a standardized production process, which is applicable to different vehicles and improves the production efficiency of the vehicle.

[0008] Furthermore, the trigger threshold is dynamically corrected and tested according to the actual anti-pinch force and the target anti-pinch force to obtain the target trigger threshold, and the steps include: when the actual anti-pinch force is greater than the target anti-pinch force, reducing the trigger threshold to obtain a corrected trigger threshold, and using the corrected trigger threshold for the next calibration test; when the actual anti-pinch force is less than the target anti-pinch force, increasing the trigger threshold to obtain a corrected trigger threshold, and using the corrected trigger threshold for the next calibration test; when the actual anti-pinch force obtained after a preset number of consecutive tests is equal to the target anti-pinch force, the trigger threshold corresponding to this test is used as the target trigger threshold.

[0009] In this technical solution, by comparing the actual anti-pinch force detected when the anti-pinch function is triggered with the target anti-pinch force, it is possible to ensure that the window anti-pinch function reaches the expected force value when triggered, thereby avoiding safety hazards or functional failures caused by excessive or insufficient force values. Furthermore, based on the comparison results of the actual anti-pinch force and the target anti-pinch force, the trigger threshold is dynamically adjusted, and multiple calibration tests and corrections are performed to determine the target trigger threshold that meets the target anti-pinch force, thereby improving the stability and safety of the anti-pinch function.

[0010] Furthermore, the step of reducing the trigger threshold to obtain a revised trigger threshold includes: reducing the trigger threshold to the revised trigger threshold according to a first correction rule.

[0011] In this technical solution, the trigger threshold is corrected according to the first correction rule by setting the single adjustment step of the trigger threshold to avoid the single adjustment step of the trigger threshold being too large or too small, so that the trigger threshold can gradually approach the target trigger threshold corresponding to the target anti-pinch force. By gradually approaching, a suitable trigger threshold can be found within a small number of tests, thereby improving the efficiency of the dynamic correction process.

[0012] Furthermore, the step of increasing the trigger threshold to obtain a revised trigger threshold includes: increasing the trigger threshold to the revised trigger threshold according to a second correction rule.

[0013] In this technical solution, the trigger threshold is corrected according to the second correction rule by setting the single adjustment step of the trigger threshold to avoid the single adjustment step of the trigger threshold being too large or too small, so that the trigger threshold can gradually approach the target trigger threshold corresponding to the target anti-pinch force. By gradually approaching, the appropriate trigger threshold can be found within a small number of tests, thereby improving the efficiency of the dynamic correction process.

[0014] Furthermore, the step of obtaining first operating data of the window assembly under the load operating state includes: when the window assembly is in the load operating state, obtaining the operating current of the window assembly or the motor speed of the window assembly, and obtaining the operating voltage of the window assembly or the operating stroke of the window; generating first operating data, i.e., a first characteristic curve, based on the current or speed, voltage or stroke.

[0015] In this technical solution, the window assembly is controlled to be raised normally without any obstacles. In this process, the operating current of the window assembly or the motor speed of the window assembly is collected, and the operating voltage of the window assembly or the operating stroke of the window is obtained. Based on the collected data, a first characteristic curve in the process of window raising is drawn, so as to display the relevant display of the operating parameters when the window is in the normal raising process through the first characteristic curve.

[0016] Furthermore, second operating data of the window assembly under a target load state is obtained; when a target load is applied to a target position of the window assembly, an operating current of the window assembly or a motor speed of the window assembly is obtained, as well as an operating voltage of the window assembly or an operating stroke of the window is obtained; and second operating data, i.e., a second characteristic curve, is generated based on the current or speed, voltage or stroke.

[0017] In this technical solution, by simulating the situation that the window encounters an obstacle during the rising process, the operating parameters of the window during the rising process, including the current or motor speed, and the voltage or the travel of the window, are obtained. The second operating data, i.e., the second characteristic curve, is generated through the current or speed, voltage or travel. Combined with the second characteristic curve, the changes in the operating parameters when the window encounters an obstacle are shown.

[0018] Furthermore, based on the first operating data and the second operating data, the step of obtaining a triggering threshold for triggering the window anti-pinch function includes: fitting the first characteristic curve to obtain a fitted first characteristic curve; fitting the second characteristic curve to obtain a fitted second characteristic curve; the current value or speed value corresponding to the intersection of the fitted second characteristic curve and the first characteristic curve is the triggering threshold for triggering the window anti-pinch function.

[0019] In this technical solution, the first operating data and the second operating data are obtained under the same test environment. Fitting is performed on the first characteristic curve and the second characteristic curve to obtain a smooth characteristic curve. The fitted second characteristic curve is compared with the first characteristic curve to find their intersection. The current value or speed value corresponding to the intersection is the trigger threshold for triggering the window anti-pinch function. This threshold indicates that when the current or speed reaches this value, the window assembly should activate the anti-pinch function and stop the rising action to avoid causing harm to passengers.

[0020] Furthermore, before the steps of obtaining the first operating data of the window assembly under the load operating state and applying the second operating data under the target load state, it also includes: obtaining configuration information of the operating condition, and performing initialization operations of the operating condition according to the configuration information; wherein the configuration information includes the test environment temperature, the test environment humidity, and the test points of the anti-pinch force; the configuration information also includes one of the operating voltage of the window assembly or the operating range of the window.

[0021] In this technical solution, before the calibration test of the window anti-pinch function is carried out, the configuration information of the operating condition is determined according to the working condition scenario in actual use. And according to the determined configuration information, the initialization operation of the operating condition is performed, that is, the configuration of the operating condition scenario is completed, so that the trigger threshold obtained by calibration can meet the requirements of the working condition scenario of actual application, and the stability and safety of the calibrated anti-pinch function during use are improved.

[0022] The present application also proposes a calibration system for the window anti-pinch function, including: a calibration master control module, a data interaction module and a detection module. Among them, the data interaction module is used to obtain the first operating data under the load operating state of the window assembly and the second operating data under the target load application state. The calibration master control module is used to obtain the trigger threshold for triggering the window anti-pinch function according to the first operating data and the second operating data. The detection module is used to detect the actual anti-pinch force when the window anti-pinch function is triggered using an anti-pinch tester during the dynamic calibration test under different operating conditions; the calibration master control module is also used to dynamically correct and test the trigger threshold according to the actual anti-pinch force and the target anti-pinch force to obtain the target trigger threshold.

[0023] The present application also proposes a calibration device for the vehicle window anti-pinch function, comprising a processor and a memory storing program instructions. The processor is configured to execute the calibration method for the vehicle window anti-pinch function as described in any of the above technical solutions when running the program instructions.

[0024] The present application also proposes a readable storage medium storing program instructions, which, when executed, are used to enable a computer to execute the calibration method for the vehicle window anti-pinch function as described in any of the above technical solutions.

[0025] The present application also proposes a vehicle, comprising: a calibration system for the window anti-pinch function as described in any of the above technical solutions; or a calibration device for the window anti-pinch function as described in any of the above technical solutions.

[0037] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0039] In some embodiments, in combination Figure 1 As shown, the present application proposes a calibration method for the window anti-pinch function, comprising:

[0040] S101, obtaining first operating data of a vehicle window assembly under a load operating state.

[0041] S102, obtaining second operating data of the window assembly under a target load condition.

[0042] S103, obtaining a triggering threshold for triggering a window anti-pinch function according to the first operating data and the second operating data.

[0043] S104, during the dynamic calibration test under different operating conditions, using an anti-pinch tester to detect the actual anti-pinch force when the anti-pinch function of the vehicle window is triggered.

[0044] S105 , dynamically correcting and testing the trigger threshold according to the actual anti-pinch force and the target anti-pinch force to obtain the target trigger threshold.

[0045] The calibration method of the window anti-pinch function provided by the present application, first, in the process of the window assembly rising, the whole process is in the load operation state, and the first operation data of the window assembly operation is obtained. Then, a simulated obstacle is set in the rising path of the window to apply a target load to the window assembly, that is, the target load is set according to the national standard as an additional load to be applied. The second operation data of the window assembly under the condition of applying the target load is obtained. Through the first operation data and the second operation data, the corresponding data when the operation parameters of the window assembly change when the window encounters the simulated obstacle during the rising process is determined as the trigger threshold for triggering the window anti-pinch function. Then, for the obtained trigger threshold, multiple dynamic calibration tests are performed to repeatedly test and adjust the trigger threshold until the window can accurately stop and move in the opposite direction when encountering an obstacle. Further, in order to improve the accuracy of the anti-pinch function triggering, the trigger threshold is calibrated and tested for a variety of different operating conditions in the calibration link to adapt to different environmental conditions and window states, to ensure that the anti-pinch function can work reliably in various situations, thereby improving the stability and safety of the anti-pinch function operation. Specifically, during the test, the anti-pinch tester is used to detect the actual anti-pinch force when the window anti-pinch function is triggered. If the actual anti-pinch force cannot meet the target anti-pinch force, the trigger threshold is dynamically corrected, and the corrected trigger threshold is tested again. In this way, by repeatedly correcting the trigger threshold, the actual anti-pinch force when the anti-pinch function is triggered can continuously approach the target anti-pinch force, thereby improving the accuracy of the anti-pinch function triggering.

[0046] By adopting the calibration method of the vehicle window anti-pinch function provided by the present application, the accurate calibration of the triggering threshold of the anti-pinch function can be improved, thereby reducing the maintenance and adjustment caused by the inaccurate anti-pinch function, and reducing the initial testing cost and the later maintenance cost. In addition, the calibration method of the vehicle window anti-pinch function provided by the present application can complete the calibration of the vehicle window anti-pinch function under the window control simulation system constructed by software, and is also applicable to the physical window controller for the calibration of the vehicle window anti-pinch function. Compared with the physical vehicle test in the related art, the testing cost is reduced and the testing cycle is shortened. In addition, the calibration method of the vehicle window anti-pinch function provided by the present application can be used as a standardized production process, which is applicable to different vehicles and improves the production efficiency of vehicles.

[0047] In some embodiments, in combination Figure 2 As shown, the present application provides a method for dynamically modifying and testing a trigger threshold, including:

[0048] S201, complete the initialization of the test condition, control the operation of the window assembly, and perform the anti-pinch function calibration test.

[0049] S202, when the operating parameters of the window assembly meet the triggering threshold, triggering the window anti-pinch function.

[0050] S203, using an anti-pinch tester, obtaining an actual anti-pinch force when the anti-pinch function of the vehicle window is triggered.

[0051] S204, comparing the actual anti-pinch force with the target anti-pinch force.

[0052] S205 , when the actual anti-pinch force is greater than the target anti-pinch force, reducing the trigger threshold to obtain a corrected trigger threshold.

[0053] S206, updating the trigger threshold to the corrected trigger threshold, and performing the next calibration test.

[0054] When the actual anti-pinch force is greater than the target anti-pinch force, it means that the actual anti-pinch force is too large, that is, the trigger threshold is too large, resulting in the anti-pinch function not being triggered in time. Therefore, it is necessary to reduce the trigger threshold to reduce the actual anti-pinch force. In this way, by adjusting the trigger threshold so that the actual anti-pinch force approaches the target anti-pinch force, the safety of the anti-pinch function can be improved. The trigger threshold is updated to the reduced trigger threshold, and the reduced trigger threshold is tested again until the actual anti-pinch force is infinitely close to or equal to the target anti-pinch force.

[0055] S207, when the actual anti-pinch force is less than the target anti-pinch force, increase the trigger threshold to obtain a corrected trigger threshold.

[0056] S208, updating the trigger threshold to the corrected trigger threshold, and performing the next calibration test.

[0057] When the actual anti-pinch force is less than the target anti-pinch force, it means that the actual anti-pinch force is too small, that is, the trigger threshold is too small, and the anti-pinch function is triggered prematurely. Therefore, the trigger threshold needs to be increased to increase the actual anti-pinch force. In this way, by adjusting the trigger threshold, the actual anti-pinch force is close to the target anti-pinch force, so as to improve the stability of the anti-pinch function. The trigger threshold is updated to the increased trigger threshold, and the increased trigger threshold is tested again until the actual anti-pinch force is infinitely close to or equal to the target anti-pinch force.

[0058] S209, when the actual anti-pinch force is equal to the target anti-pinch force, the trigger threshold remains unchanged, and the number of tests in which the actual anti-pinch force is equal to the target anti-pinch force is counted.

[0059] S210: When the number of tests is less than the preset number of tests, perform the next calibration test.

[0060] S211, when the number of tests reaches a preset number of times, the corresponding trigger threshold is used as the target trigger threshold.

[0061] When the actual anti-pinch force is equal to the target anti-pinch force, it means that the current trigger threshold can accurately trigger the window anti-pinch function, and the trigger threshold remains unchanged. And count the number of tests when the actual anti-pinch force is equal to the target anti-pinch force. After the preset number of calibration tests, and the results of the preset number of calibration tests are that the actual anti-pinch force is equal to the target anti-pinch force, it means that the stability and accuracy of the current trigger threshold are better, thereby improving the accuracy of the calibration data.

[0062] In this embodiment, by comparing the actual anti-pinch force detected when the anti-pinch function is triggered with the target anti-pinch force, it is possible to ensure that the window anti-pinch function reaches the expected force value when triggered, thereby avoiding safety hazards or functional failures caused by excessive or insufficient force values. Furthermore, based on the comparison results of the actual anti-pinch force and the target anti-pinch force, the trigger threshold is dynamically adjusted, and multiple calibration tests and corrections are performed to determine the target trigger threshold that meets the target anti-pinch force, so as to improve the stability and safety of the anti-pinch function triggering.

[0063] Optionally, the target anti-pinch force has a value range of 60N to 90N. The specific value of the target anti-pinch force includes but is not limited to: 60N, 70N, 80N or 90N. Set the target anti-pinch range, and set the range that can float up and down based on the target anti-pinch force to improve the calibration efficiency. The floating range can be specifically set according to the accuracy requirements of the specific vehicle, and is not specifically limited here.

[0064] In some embodiments, the step of reducing the trigger threshold to obtain a revised trigger threshold includes: reducing the trigger threshold to the revised trigger threshold according to a first correction rule.

[0065] In this embodiment, the trigger threshold is corrected according to the first correction rule by setting the single adjustment step of the trigger threshold to avoid the single adjustment step of the trigger threshold being too large or too small, so that the trigger threshold can gradually approach the target trigger threshold corresponding to the target anti-pinch force. By gradually approaching, a suitable trigger threshold can be found within a small number of tests, thereby improving the efficiency of the dynamic correction process.

[0066] In some embodiments, the step of increasing the trigger threshold to obtain a revised trigger threshold includes: increasing the trigger threshold to the revised trigger threshold according to a second correction rule.

[0067] In this embodiment, the trigger threshold is corrected according to the second correction rule by setting the single adjustment step of the trigger threshold to avoid the single adjustment step of the trigger threshold being too large or too small, so that the trigger threshold can gradually approach the target trigger threshold corresponding to the target anti-pinch force. By gradually approaching, a suitable trigger threshold can be found within a relatively small number of tests, thereby improving the efficiency of the dynamic correction process.

[0068] Optionally, the first correction rule is: A n+1 =A n -K n , K n+1 =K n ×k, where A n is the trigger threshold of this test, A n+1 is the corrected trigger threshold for the next test, K is the adjustment step, k is the adjustment coefficient, n is the number of tests, and the value of n is 1, 2, 3…

[0069] Optionally, the second correction rule is: A n+1 =A n +K n , K n+1 =K n ×k, where A n is the trigger threshold of this test, A n+1 is the corrected trigger threshold for the next test, K is the adjustment step, k is the adjustment coefficient, n is the number of tests, and the value of n is 1, 2, 3…

[0070] Optionally, the value range of k is: 0<k1<1. The specific value of k includes but is not limited to: 1 / 2, 1 / 3, 1 / 4 or 1 / 5. By setting the adjustment coefficient, a suitable adjustment step can be determined to improve the accuracy and efficiency of adjusting the trigger threshold.

[0071] Optionally, the value of k is proportional to the difference between the target anti-pinch force and the actual anti-pinch force. The greater the difference between the target anti-pinch force and the actual anti-pinch force, the greater the value of k. The smaller the difference between the target anti-pinch force and the actual anti-pinch force, the smaller the value of k. In this way, the appropriate adjustment step can be determined according to the difference between the target anti-pinch force and the actual anti-pinch force to improve the adjustment accuracy and efficiency.

[0072] Exemplarily, the target anti-pinch force is set to 80N, and the target anti-pinch range is set to 80±0.5N. When the actual anti-pinch force is within this range, it is considered to be close to 80N, satisfying the anti-pinch calibration. The value of k1 is 1 / 2. The trigger threshold of this test is the speed trigger threshold. The ripple period A1 corresponding to the speed trigger threshold is 300Hz. The actual anti-pinch force detected when the anti-pinch function is triggered is 120N. If the actual anti-pinch force 120N> the target anti-pinch force 80N, the first correction rule is used to correct the trigger threshold A1 this time, and the first adjustment step K1 is set to 100Hz to obtain the corrected trigger threshold: A2=A1-K1=300-100=200(Hz). The trigger threshold is updated to A2 for the next calibration test.

[0073] In the next calibration test, the actual anti-pinch force N2=72 is detected. The actual anti-pinch force 72N<the target anti-pinch force 80N. Then the second correction rule is used to correct the trigger threshold A2. The second adjustment step K 2＝ K1×1 / 2=50Hz, and the corrected trigger threshold is obtained: A3=A2+K2=200+50=250(Hz). The trigger threshold is updated to A3 and the next calibration test is performed.

[0074] And so on, as shown in Table 1, until the actual anti-pinch force approaches 80N, and after a preset number of verifications, the results are all satisfied, and finally the corresponding trigger threshold is determined to be the target trigger threshold.

[0077] Optionally, the step of obtaining the first operating data of the window assembly under the load operating state includes: when the window assembly is under the load operating state, obtaining the operating current of the window assembly or the motor speed of the window assembly, and obtaining the operating voltage of the window assembly or the operating stroke of the window. The first operating data, i.e., the first characteristic curve, is generated according to the current or speed, voltage or stroke.

[0078] In this embodiment, according to the national safety standard, a target load, such as 80N, is selected, and the target load is kept applied to the window during the entire process of controlling the window to rise from the bottom to the top. During this process, the operating current of the window assembly or the motor speed of the window assembly is collected, and the operating voltage of the window assembly or the operating stroke of the window is obtained. Based on the collected data, a first characteristic curve in the process of window rising is drawn, so as to display the relevant display of the operating parameters of the window in the process of full load rising through the first characteristic curve.

[0079] Combination Figure 4As shown, the X-axis is time and the Y-axis is the operating current of the window assembly. Among them, the curve corresponding to line A is: when the window assembly is controlled without additional load, the window is raised from the bottom to the top, and the corresponding relationship curve between the current and time is obtained. And the curve corresponding to line B is: when the target load is applied to the window assembly, and the same load is applied during the entire rising process of the window, the corresponding relationship curve between the current and time collected during the rising process of the window from the bottom to the top is obtained. Comparing lines A and B, it can be seen that the corresponding operating current during the normal rising process of the window without additional load is less than the operating current when the target load is applied to the window. That is, when the window encounters an obstacle during the rising process, the operating current increases. Among them, applying a target load to the window can be achieved by setting weights in the rising path of the window to simulate obstacles. The specific value selection of the target load can be specifically set according to national safety standards, and calibration tests can be performed to improve the stability and safety of the operation of the window anti-pinch function after calibration.

[0080] In one example, different voltage values ​​are set through a voltage-stabilized power supply to simulate the working state of the window assembly under different power supply voltages, and a characteristic curve of voltage and current, or a characteristic curve of voltage and motor speed is generated based on the voltage, current or motor speed detected during the window raising process.

[0081] In one example, according to the change in the distance of the window being raised, the change in current or motor speed during the raising process is recorded to generate a characteristic curve of distance and current, or a characteristic curve of distance and motor speed.

[0082] Optionally, use MATLAB to obtain a sliding average curve of the first characteristic curve to filter out the harmonics of the ripple. The sliding window is selected to be twice the ripple period. That is, if the ripple period is T, the sliding window size should be 2T. In this way, the harmonic components in the ripple can be effectively filtered out while retaining the main trend of the curve. By applying a sliding average, the influence of harmonics can be reduced, thereby obtaining a smoother current equivalent DC component to more accurately reflect the actual working state of the motor. Combined with Figure 5 As shown, it is a curve of the relationship between current and window travel, wherein curve C is the curve before fitting, and curve C' is the curve after filtering fitting. By comparison, it can be seen that by fitting and filtering the curve, the influence of harmonics can be reduced, thereby improving the stability and accuracy of the curve.

[0083] Optionally, the second operating data of the window assembly under the target load state is obtained. Under the target load state at the target position of the window assembly, the operating current of the window assembly or the motor speed of the window assembly is obtained, and the operating voltage of the window assembly or the operating stroke of the window is obtained. The second operating data, i.e., the second characteristic curve, is generated according to the current or speed, voltage or stroke.

[0084] In this embodiment, a target position is selected in the window rising path to set an obstacle, the window is controlled to start rising, and the operating parameters of the window during the rising process are obtained, including the current or motor speed, and the voltage or the travel of the window. And the second operating data, that is, the second characteristic curve, is generated through the current or speed, voltage or travel. Combined with the second characteristic curve, the changes in the operating parameters when the window encounters an obstacle are displayed. Among them, multiple target positions can be selected, including but not limited to 1 / 6, 5 / 6, 1 / 5, 2 / 5, 3 / 5, 4 / 5, 1 / 4, 3 / 4, 1 / 3, 2 / 3 or 1 / 2 of the window travel, etc., and each target position can be tested and calibrated separately, thereby improving the comprehensiveness of the calibration position and improving the stability and safety of the window anti-pinch function after calibration.

[0085] In one example, under different voltage conditions, the change in current or motor speed during the rising process is recorded, and the change in current over time is measured and recorded to form a second characteristic curve.

[0086] In one example, according to the change in the window raising distance, the change in current or motor speed during the raising process is recorded to generate a second characteristic curve of distance and current, or a second characteristic curve of distance and motor speed.

[0087] For example, according to national safety standards, the actual anti-pinch force corresponding to the triggering of the window anti-pinch function needs to be within a safe range to avoid harm to the user, and the safety range is 60N to 90N. In this example, multiple target positions are selected in the rising path of the window, and a target load is set for each target position. Taking 80N as an example, the current or motor speed during the window rising process, and the voltage or window travel under different voltage conditions are obtained respectively to form a curve relationship between the operating parameters during the window rising process. For example, the curve between current and voltage, the curve between current and window travel, the curve between motor speed and voltage, and the curve between motor speed and window travel. Through these curves, it can be seen that the changes in the operating parameters during the window rising process under different working conditions, and the performance of the operating parameters when the window encounters obstacles can be shown.

[0088] It should be noted that in actual testing, the target load simulation is not limited to 80N, but can also be set to 60N, 70N, 85N or 90N. Any load that meets national safety standards can be tested and calibrated to improve the comprehensiveness of the test calibration. The method of simulating the target load includes but is not limited to using weights or other items that are easy to weigh.

[0089] Optionally, the step of obtaining a triggering threshold for triggering the window anti-pinch function according to the first operating data and the second operating data includes: performing polynomial fitting on the second characteristic curve to obtain a fitted second characteristic curve. The current value or speed value corresponding to the intersection of the fitted second characteristic curve and the first characteristic curve is the triggering threshold for triggering the window anti-pinch function.

[0090] In this embodiment, the first operating data and the second operating data are obtained under the same operating conditions. A polynomial fitting is performed on the second characteristic curve to obtain a smooth characteristic curve. The fitted second characteristic curve is compared with the first characteristic curve to find their intersection. The current value or speed value corresponding to the intersection is the trigger threshold for triggering the window anti-pinch function. This threshold indicates that when the current or speed reaches this value, the window assembly should activate the anti-pinch function and stop the rising action to avoid causing harm to passengers.

[0091] Optionally, for the second characteristic curve, a polynomial fitting is performed to obtain a smooth characteristic curve, and the step includes: using the curve fitting toolbox (cftool) of MATLAB, selecting a polynomial fitting model in cftool to perform polynomial fitting on the second characteristic curve to obtain a characteristic curve of the anti-pinch trigger current. Here, according to the consistency of the window working condition and the requirements of calibration accuracy, the polynomial fitting model can be fitted using a 3rd to 4th order function. If the consistency of the window working condition is good or the calibration accuracy requirement is not high, the polynomial fitting model can be fitted using a linear function or a constant function. In cftool, define the window height (X1) and voltage (X2) as independent variables, and the anti-pinch trigger current as the dependent variable (Y). The second characteristic curve after fitting is a function of the window height and voltage, that is, Y=F(X1, X2), where Y is the current and X1 is the window height, that is, the window travel. X2 is the voltage.

[0092] Combination Figure 6 As shown, the X-axis is the window operation time, and the Y-axis is the window assembly operation current. Curve D is the first characteristic curve after fitting, curve E is the second characteristic curve before fitting, and curve E' is the second characteristic curve after fitting. Among them, the test environment temperature, humidity and voltage in the working condition information of the first characteristic curve and the second characteristic curve are the same, and the simulated load used is 80N. Figure 4 As shown in the figure, when the car window hits an obstacle, the current will increase. Observing curve D and curve E', the current of curve E' increases during the rising process of the car window and intersects with curve D. That is, the current value corresponding to the intersection G is the trigger threshold of the anti-pinch function under this working condition. Figure 6 As shown in the figure, after the intersection G, the current value decreases after a certain amplitude occurs, that is, after the anti-pinch function is triggered, the motor reverses, the window drops, and the current begins to decrease and stabilizes. Figure 6 As shown, the corresponding curve in box M is the operating curve of the process of the window rising to encountering an obstacle, and the corresponding curve in box N is the operating parameter of the window assembly after the window anti-pinch function is triggered. The trigger threshold determined by the first characteristic curve and the second characteristic curve is further corrected by the dynamic correction and testing method in the above embodiment, and finally the target trigger threshold is obtained to improve the accuracy and comprehensiveness of the calibration of the window anti-pinch function, thereby improving the stability and safety of the operation of the window anti-pinch function.

[0093] Optionally, before the steps of obtaining the first operating data of the window assembly under the load operating state and applying the second operating data under the target load state, the method further includes: obtaining configuration information of the operating condition, and performing initialization operation of the operating condition according to the configuration information. The configuration information includes the test environment temperature, the test environment humidity, and the test point of the anti-pinch force. The configuration information also includes one of the operating voltage of the window assembly or the operating travel of the window.

[0094] In this embodiment, before the calibration test of the window anti-pinch function is performed, the configuration information of the operating condition is determined according to the working condition scenario in actual use. And according to the determined configuration information, the initialization operation of the operating condition is performed, that is, the configuration of the operating condition scenario is completed, so that the trigger threshold obtained by calibration can meet the requirements of the working condition scenario of actual application, and the stability and safety of the calibrated anti-pinch function during use are improved.

[0095] The configuration information includes: ambient temperature and test environment humidity, so that the consistency and reliability of the test under different temperatures and humidity can be adapted to different ambient temperatures and humidity. Furthermore, other equipment in the temperature and humidity simulation cabin can be used to change the test environment temperature and humidity to evaluate the reliability of the window anti-pinch function under different environmental conditions.

[0096] Configuration information includes: test points. There are multiple test points to determine the specific positions where the anti-pinch force test is required during the window's rise, so that multiple positions of the window can be calibrated to improve the stability and safety of the anti-pinch function. Figure 3 As shown, for a vehicle window with a bent top, a test point b is set at the bend, and multiple test points a and c are respectively set in the areas on both sides of the bend to improve the comprehensiveness and accuracy of the anti-pinch function calibration.

[0097] Configuration information includes: The operating voltage of the window assembly. The output torque of the window motor is directly related to the voltage applied to the motor. When the voltage of the external power supply changes, the output torque of the motor will also change accordingly. By configuring the operating voltage, it is possible to test that the anti-pinch function works properly under different power supply conditions. Among them, different voltage values ​​are set through the voltage-stabilized power supply to simulate the working state of the vehicle under different power supply voltages, so as to test the performance of the window anti-pinch function under these conditions.

[0098] Configuration information includes: the travel range of the window. By configuring the travel range of the window, it is possible to test whether the anti-pinch function can work properly at different window heights. The anti-pinch tester is adjusted to test at different target positions so that accurate testing can be performed at different window heights.

[0099] In some embodiments, in combination Figure 7 As shown, a calibration system 700 for the window anti-pinch function is also proposed, including: a calibration master control module 710, a data interaction module 720 and a detection module 730. Among them, the data interaction module 720 is used to obtain the first operating data under the load operating state of the window assembly and the second operating data under the target load application state. The calibration master control module 710 is used to obtain the triggering threshold for triggering the window anti-pinch function according to the first operating data and the second operating data. The detection module 730 is used to detect the actual anti-pinch force when the window anti-pinch function is triggered by using an anti-pinch tester during the dynamic calibration test under different operating conditions. The calibration master control module 710 is also used to dynamically correct and test the triggering threshold according to the actual anti-pinch force and the target anti-pinch force to obtain the target triggering threshold.

[0100] In this embodiment, by adopting the calibration system of the window anti-pinch function provided by the present application, the accurate calibration of the triggering threshold of the anti-pinch function can be improved, thereby reducing the maintenance and adjustment caused by the inaccurate anti-pinch function, and reducing the initial testing cost and the later maintenance cost. In addition, the calibration method of the window anti-pinch function provided by the present application can complete the calibration of the window anti-pinch function under the window control simulation system constructed by software, and is also applicable to the calibration of the window anti-pinch function of the physical window assembly and the window controller. Compared with the physical vehicle test in the related art, the testing cost is reduced and the testing cycle is shortened. In addition, the calibration method of the window anti-pinch function provided by the present application can be used as a standardized production process, which is applicable to different vehicles and improves the production efficiency of the vehicle.

[0101] Optionally, the calibration system 700 further includes a tested module 740, and the calibration master control module 710 is further used to send an operation instruction to the tested module. The tested module 740 includes a vehicle window controller 742 and a vehicle window assembly 744. The vehicle window controller is used to control the operation of the vehicle window assembly according to the operation instruction sent by the calibration master control module.

[0102] Optionally, the calibration master control module 710 is also used to obtain configuration information of the operating condition and perform initialization operation of the operating condition according to the configuration information. The configuration information includes the test environment temperature, the test environment humidity, and the test point of the anti-pinch force. The configuration information also includes one of the operating voltage of the vehicle window assembly or the operating travel of the vehicle window.

[0103] Optionally, the calibration master control module 710 also includes a window control simulation system, which is software developed using programming languages ​​such as MATLAB and Python to simulate the behavior of a vehicle window controller so as to perform testing and calibration without an actual controller. In particular, the plot function of MATLAB can be used to draw a picture for intuitive analysis.

[0104] Optionally, the data interaction module 720 uses the trace·snooper function of Lauterbach's trace32 debugger to capture current data, and then uses the python script tool to create a streaming file for trace32 parsing and log storage. And, support CAN FD high-speed bus diagnostic equipment for vehicle network communication data collection and analysis. And, use a network camera to record the working conditions of the window to eliminate external interference. The calibration master control module makes a window raising request, and completes the window control request action through the window raising and lowering related parameters in the trace32 practice script control program.

[0105] Optionally, the anti-pinch tester starts to collect actual anti-pinch force data. Similarly, Python is used to create a streaming file for data transmission. The data of the anti-pinch tester and trace32 are synchronized according to the system time so that the upper-level calibration master control module can analyze it.

[0106] Optionally, the calibration system 700 further includes: a programmable power supply and a temperature and humidity simulation chamber. The programmable power supply is used to simulate different power supply conditions, such as different voltage conditions. The temperature and humidity simulation chamber is used to simulate different environmental conditions to test the performance of the window anti-pinch function under these conditions. The anti-pinch tester needs to be able to measure the anti-pinch force at different window heights to ensure the consistency of the anti-pinch function throughout the entire travel.
