Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of car window anti-pinch, and in particular to a car window anti-pinch function calibration method, system, device, readable storage medium and vehicle. BACKGROUND

[0002] In order to meet the needs of drivers and passengers to frequently open and close the windows, for example, when paying for parking in a parking lot, passing through a toll station or communicating with others. The windows of the car are designed as electric windows that can automatically lift and lower. The electric windows that can automatically lift and lower improve the user experience. At the same time, there are some potential safety hazards. For example, the automatic lifting and lowering function is unstable or faulty, which can cause the car window to pinch the hands or other objects of the passengers.

[0003] In order to improve the safe use, the electric windows that can automatically lift and lower increase the car window anti-pinch function. The car window anti-pinch function is to stop the closing action of the window in the case that the hands, fingers, even the body parts of pets, and other objects are stuck on the window during the closing of the window, in order to avoid causing harm. In order to test the stability of the operation of the car window anti-pinch function, in the related art, a method for testing the anti-pinch function of the car window assembly is provided. The anti-pinch function of the car window assembly of the physical vehicle is tested before the vehicle is put into production, in order to improve the pre-delivery detection of the stability of the anti-pinch function. However, this testing method requires testing on the physical vehicle. If the test is not qualified, the car window assembly and the control system need to be reworked, thereby increasing the testing cost and the production cost. And the whole testing cycle is long, which leads to low testing efficiency, thereby affecting the production efficiency of the whole vehicle. SUMMARY

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

[0005] In order to achieve the above-mentioned purposes, the technical solutions adopted by the present application are as follows:

[0006] The present application provides a car window anti-pinch function calibration method, which comprises: obtaining first running data in a car window assembly load running state and second running data in a target load state; obtaining a trigger threshold value of the car window anti-pinch function according to the first running data and the second running data; during dynamic calibration testing under different operating conditions, using an anti-pinch tester to detect the actual anti-pinch force when the car window anti-pinch function is triggered; and dynamically correcting and testing the trigger threshold value according to the actual anti-pinch force and a target anti-pinch force, in order to obtain a target trigger threshold value.

[0007] By adopting the calibration method of the window anti-pinch function provided in the application, the accuracy of the calibration of the trigger threshold of the anti-pinch function can be improved, and the maintenance and adjustment caused by the inaccuracy of the anti-pinch function can be reduced, thereby reducing the test cost in the early stage and the maintenance cost in the later stage. Moreover, the calibration method of the window anti-pinch function provided in the application can be used to complete the calibration of the window anti-pinch function under a window control simulation system constructed by software, and is also applicable to the calibration of the window anti-pinch function of the entity window assembly and the window controller. Compared with the entity vehicle test in the related art, the test cost is reduced, and the test period is shortened. Moreover, the calibration method of the window anti-pinch function provided in the application can be used as a standardized production process and is applicable to different vehicles, thereby improving the production efficiency of the vehicle.

[0008] Further, the step of 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 comprises: in the case that 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; in the case that 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; in the case that the actual anti-pinch force obtained by continuous preset times of testing is equal to the target anti-pinch force, using the trigger threshold corresponding to the current test as the target trigger threshold.

[0009] In the technical solution, by comparing the actual anti-pinch force detected when the anti-pinch function is triggered with the target anti-pinch force, it can be ensured that the window anti-pinch function reaches the expected force value when triggered, thereby avoiding safety hazards or function failure caused by excessively large or small force values. Further, according to the comparison result 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] Further, the step of reducing the trigger threshold to obtain a corrected trigger threshold comprises: reducing the trigger threshold to the corrected trigger threshold according to a first correction rule.

[0011] In the technical solution, the single adjustment step of the trigger threshold is corrected according to the first correction rule, so as to avoid excessively large or small single adjustment step of the trigger threshold, and make the trigger threshold gradually approach the target trigger threshold corresponding to the target anti-pinch force. By gradually approaching, the appropriate trigger threshold can be found in a smaller number of test times, thereby improving the efficiency of the dynamic correction process.

[0012] Further, the step of increasing the trigger threshold to obtain a corrected trigger threshold comprises: increasing the trigger threshold to the corrected trigger threshold according to a second correction rule.

[0013] In the technical solution, the single adjustment step of the triggering threshold is modified according to the second modification rule to avoid the single adjustment step of the triggering threshold being too large or too small, so that the triggering threshold can gradually approach the target triggering threshold corresponding to the target anti-pinch force. By gradually approaching, the appropriate triggering threshold can be found in a smaller number of tests, improving the efficiency of the dynamic modification process.

[0014] Further, the step of obtaining the first running data of the vehicle window assembly in a load running state comprises: obtaining the running current of the vehicle window assembly or the motor speed of the vehicle window assembly, and obtaining the running voltage of the vehicle window assembly or the running stroke of the vehicle window, when the vehicle window assembly is in a load running state; and generating the first running data, i.e., the first characteristic curve, according to the current or speed, voltage or stroke.

[0015] In the technical solution, the vehicle window assembly is controlled to normally rise without obstruction. In this process, the running current of the vehicle window assembly or the motor speed of the vehicle window assembly, and the running voltage of the vehicle window assembly or the running stroke of the vehicle window are collected. According to the collected data, the first characteristic curve in the process of raising the vehicle window is drawn to show the relevant display of the running parameters of the vehicle window in the normal raising process through the first characteristic curve.

[0016] Further, the second running data of the vehicle window assembly under a target load state is obtained; the running current of the vehicle window assembly or the motor speed of the vehicle window assembly, and the running voltage of the vehicle window assembly or the running stroke of the vehicle window are obtained when the target load state is applied to the target position of the vehicle window assembly; and the second running data, i.e., the second characteristic curve, is generated according to the current or speed, voltage or stroke.

[0017] In the technical solution, by simulating the situation that the vehicle window encounters an obstacle in the process of rising, the running parameters of the vehicle window in the process of rising are obtained, including the current or motor speed, and the voltage or stroke of the vehicle window. And the second running data, i.e., the second characteristic curve, is generated according to the current or speed, voltage or stroke. Combined with the second characteristic curve, the changes of the running parameters when the vehicle window encounters an obstacle are displayed.

[0018] Further, the step of obtaining the triggering threshold for triggering the anti-pinch function of the vehicle window according to the first running data and the second running data comprises: fitting the first characteristic curve to obtain the fitted first characteristic curve; fitting the second characteristic curve to obtain the fitted second characteristic curve; and 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 anti-pinch function of the vehicle window.

[0019] In the technical solution, the first running data and the second running data are respectively acquired under the same test environment. The first characteristic curve and the second characteristic curve are fitted to obtain a smooth characteristic curve. The fitted second characteristic curve is compared with the first characteristic curve to find the intersection point. The current value or the rotating speed value corresponding to the intersection point is the trigger threshold value of the trigger of the window anti-pinch function. The threshold value indicates that when the current or the rotating speed reaches the value, the window assembly should activate the anti-pinch function to stop the rising action to avoid causing harm to the passenger.

[0020] Further, before the steps of acquiring the first running data under the load running state of the window assembly and the second running data under the target load state, the method further comprises: acquiring configuration information of the running condition, and performing an initialization operation of the running condition according to the configuration information; wherein the configuration information comprises a test environment temperature, a test environment humidity, and a test point of the anti-pinch force; and the configuration information further comprises one of a running voltage of the window assembly or a running stroke of the window.

[0021] In the technical solution, the configuration information of the running condition is determined according to the actual use condition scene before the calibration test of the window anti-pinch function. The initialization operation of the running condition is performed according to the determined configuration information, that is, the configuration of the running condition scene is completed, so that the trigger threshold value obtained by the calibration can meet the demand of the actual application condition scene, and the stability and safety of the calibrated anti-pinch function in the use process are improved.

[0022] The application also provides a calibration system of a window anti-pinch function, comprising a calibration general control module, a data interaction module, and a detection module. The data interaction module is used to acquire first running data under a load running state of a window assembly and second running data under a target load state. The calibration general control module is used to obtain a trigger threshold value of a trigger of a window anti-pinch function according to the first running data and the second running data. The detection module is used to detect an actual anti-pinch force when the window anti-pinch function is triggered by using an anti-pinch tester in the process of dynamic calibration test under different running conditions. The calibration general control module is further used to dynamically correct and test the trigger threshold value according to the actual anti-pinch force and a target anti-pinch force to obtain a target trigger threshold value.

[0023] The application also provides a calibration device of a window anti-pinch function, comprising a processor and a memory storing program instructions. The processor is configured to execute the calibration method of the window anti-pinch function according to any one of the above technical solutions when the program instructions are executed.

[0024] The application also provides a readable storage medium storing program instructions. The program instructions are used to make a computer execute the calibration method of the window anti-pinch function according to any one of the above technical solutions when the program instructions are executed.

[0025] The application also provides a vehicle comprising the calibration system of the window anti-pinch function according to any one of the above technical solutions, or the calibration device of the window anti-pinch function according to any one of the above technical solutions.

[0037] Other advantages and benefits of the present application will become apparent to those skilled in the art upon consideration of the disclosure or can be learned by practice of the application. The present application can be realized and achieved by means other than as specifically described herein and the present application is not limited to the specific embodiments described herein. It is therefore contemplated that the application will encompass any and all such changes and modifications that fall within the true spirit and scope of the present application. It should be understood, therefore, that the preferred embodiments are merely examples of the application and are not to be taken in a limiting sense.

[0038] It is to be understood that the above description is intended to be illustrative and not restrictive. Many other embodiments will be apparent to those of skill in the art upon reading and understanding the above description. The scope of the application should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with their full scope of equivalents.

[0039] In some embodiments, in conjunction with Figure 1 As shown in the drawings, the present application provides a calibration method of a car window anti-pinch function, comprising:

[0040] S101, obtaining first running data under a running state of a target load of a car window assembly.

[0041] S102, obtaining second running data under a state of a target load applied by the car window assembly.

[0042] S103, obtaining a trigger threshold of triggering the car window anti-pinch function according to the first running data and the second running data.

[0043] S104, during a dynamic calibration test under different running conditions, detecting an actual anti-pinch force when the car window anti-pinch function is triggered by using an anti-pinch tester.

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

[0045] The calibration method of the anti-pinch function of the vehicle window provided in the application first obtains first running data of the vehicle window assembly in a full-load running state during the rising process of the vehicle window assembly. Then, a simulated obstacle is set in the rising path of the vehicle window to apply a target load to the vehicle window assembly, that is, the target load is set according to the national standard as an additional load. Second running data of the vehicle window assembly under the condition of applying the target load is obtained. Through the first running data and the second running data, the data corresponding to the change of the running parameter of the vehicle window assembly when the vehicle window encounters the simulated obstacle during the rising process is determined as the trigger threshold of the anti-pinch function of the vehicle window. Then, the trigger threshold is tested repeatedly for multiple times to test and adjust the trigger threshold until the vehicle window can stop and move reversely accurately when encountering the obstacle. Further, in order to improve the accuracy of the trigger of the anti-pinch function, the trigger threshold is calibrated and tested for multiple different running conditions in the calibration link to adapt to different environmental conditions and vehicle window states, so as to ensure that the anti-pinch function can work reliably in various situations and further improve the stability and safety of the anti-pinch function. Specifically, in the test process, the actual anti-pinch force when the anti-pinch function of the vehicle window is triggered is detected by using an anti-pinch tester. In the case that 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, the actual anti-pinch force when the anti-pinch function is triggered can continuously approach the target anti-pinch force through repeated correction of the trigger threshold, so as to improve the accuracy of the trigger of the anti-pinch function.

[0046] By using the calibration method of the anti-pinch function of the vehicle window provided in the application, the trigger threshold of the anti-pinch function can be accurately calibrated, and the maintenance and adjustment caused by the inaccuracy of the anti-pinch function can be reduced, thereby reducing the test cost in the early stage and the maintenance cost in the later stage. Moreover, the calibration method of the anti-pinch function of the vehicle window provided in the application can be used to complete the calibration of the anti-pinch function of the vehicle window under the window control simulation system constructed by software, and is also applicable to the calibration of the anti-pinch function of the vehicle window by the physical vehicle controller. Compared with the physical vehicle test in the related art, the test cost is reduced, and the test period is shortened. Moreover, the calibration method of the anti-pinch function of the vehicle window provided in the application can be used as a standardized production process and is applicable to different vehicles, thereby improving the production efficiency of the vehicles.

[0047] In some embodiments, in combination with Figure 2 As shown in the figure, the application provides a method for dynamically correcting and testing the trigger threshold, comprising:

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

[0049] S202, trigger the anti-pinch function of the vehicle window when the running parameter of the vehicle window assembly meets the trigger threshold.

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

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

[0052] S205, in the case that the actual anti-pinch force is greater than the target anti-pinch force, adjusting the trigger threshold to obtain a modified trigger threshold.

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

[0054] When the actual anti-pinch force is greater than the target anti-pinch force, it indicates that the actual anti-pinch force is too large, i.e., the trigger threshold is too large, resulting in that the anti-pinch function is not triggered in time. Therefore, the trigger threshold needs to be adjusted to be smaller, so as to reduce the actual anti-pinch force. In this way, by adjusting the trigger threshold, the actual anti-pinch force approaches the target anti-pinch force, which can improve the safety of the anti-pinch function. The trigger threshold is updated to the adjusted trigger threshold, and the adjusted trigger threshold is tested again until the actual anti-pinch force approaches or equals the target anti-pinch force.

[0055] S207, in the case that the actual anti-pinch force is less than the target anti-pinch force, adjusting the trigger threshold to obtain a modified trigger threshold.

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

[0057] When the actual anti-pinch force is less than the target anti-pinch force, it indicates that the actual anti-pinch force is too small, i.e., the trigger threshold is too small, and the anti-pinch function is triggered too early. Therefore, the trigger threshold needs to be adjusted to be larger, so as to increase the actual anti-pinch force. In this way, by adjusting the trigger threshold, the actual anti-pinch force approaches the target anti-pinch force, which can improve the stability of the anti-pinch function. The trigger threshold is updated to the adjusted trigger threshold, and the adjusted trigger threshold is tested again until the actual anti-pinch force approaches or equals the target anti-pinch force.

[0058] S209, in the case that the actual anti-pinch force equals the target anti-pinch force, the trigger threshold remains unchanged, and the number of times that the actual anti-pinch force equals the target anti-pinch force is counted.

[0059] S210, in the case that the number of times is less than a preset number of times, performing the next calibration test.

[0060] S211, in the case that the number of times reaches the preset number of times, taking the corresponding trigger threshold as a target trigger threshold.

[0061] If the actual anti-pinch force equals the target anti-pinch force, the current trigger threshold is sufficient to accurately trigger the window anti-pinch function. The trigger threshold remains unchanged. The number of tests where the actual anti-pinch force equals the target anti-pinch force is counted. If the preset number of calibration tests are completed and the results consistently show that the actual anti-pinch force equals the target anti-pinch force, the current trigger threshold is both stable and accurate, 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, thereby improving the stability and safety of the anti-pinch function.

[0063] Optionally, the target anti-pinch force ranges from 60N to 90N. Specific values ​​for the target anti-pinch force include, but are not limited to, 60N, 70N, 80N, or 90N. Setting a target anti-pinch range allows for a floating range within the target anti-pinch force to improve calibration efficiency. This floating range can be customized based on 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 adjusted according to the first correction rule by setting the single adjustment step size to avoid excessive or insufficient adjustment steps, allowing the trigger threshold to gradually approach the target trigger threshold corresponding to the target anti-pinch force. This gradual approach allows the appropriate trigger threshold to be found within a relatively small number of tests, 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 adjusted according to the second correction rule by setting the single adjustment step size. This prevents the trigger threshold from being too large or too small, allowing the trigger threshold to gradually approach the target trigger threshold corresponding to the target anti-pinch force. This gradual approach allows the appropriate trigger threshold to be found within a relatively small number of tests, 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, wherein A n is the trigger threshold of the current test, A n+1 is the trigger threshold of the next test after correction, K is the adjustment step, k is the adjustment coefficient, and n is the test number, and 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, wherein A n is the trigger threshold of the current test, A n+1 is the trigger threshold of the next test after correction, K is the adjustment step, k is the adjustment coefficient, and n is the test number, and n is 1, 2, 3, ….

[0070] Optionally, the value of k is in the range of 0 < k < 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, the appropriate adjustment step can be determined to improve the accuracy and efficiency of the trigger threshold adjustment.

[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] For example, the target anti-pinch force is set to 80N, and the target anti-pinch range is set to 80±0.5N. If the actual anti-pinch force is within this range, it is considered to approach 80N, which satisfies the anti-pinch calibration. The value of k1 is 1 / 2. The trigger threshold of the current test is the rotation speed trigger threshold, and the rotation speed trigger threshold corresponds to a ripple period A1 of 300Hz. The actual anti-pinch force detected when the anti-pinch function is triggered is 120N. The actual anti-pinch force 120N > target anti-pinch force 80N, so the first correction rule is used to correct the trigger threshold A1 of the current test. The first adjustment step K1 is set to 100Hz, and the corrected trigger threshold A2 is obtained as A2 = A1-K1 = 300-100 = 200(Hz). The trigger threshold is updated to A2 for the next calibration test.

[0073] The next calibration test, the actual anti-pinch force N2 = 72 is detected, the actual anti-pinch force 72N < target anti-pinch force 80N, then the second correction rule is used to correct the trigger threshold A2 of this time, the second adjustment step K 2= K1x1 / 2 = 50Hz, get the modified trigger threshold: A3 = A2 + K2 = 200 + 50 = 250(Hz). And update the trigger threshold as A3, perform the next calibration test.

[0074] By analogy, see Table 1, until the actual anti-pinch force approaches 80N, and after a predetermined number of checks, the results are all satisfied, and the corresponding trigger threshold is finally determined as the target trigger threshold.

[0075] Table 1

[0076] Adjustment times 1st time 2nd time 3rd time 4th time nth time This time actual anti-pinch force [N1= 120] [N2= 72] [N3= 86] [N4= 81] … Threshold adjustment step [K1 = 100] [K2 = 50] [K3 = 25] [K4 = 12] … This time set trigger threshold <![CDATA[A1=300]]> <![CDATA[A2=200]]> [A3 = 250] [A4 = 225] …

[0077] Optionally, the step of obtaining the first running data of the vehicle window assembly in the load running state comprises: obtaining the running current of the vehicle window assembly or the motor speed of the vehicle window assembly, and obtaining the running voltage of the vehicle window assembly or the running stroke of the vehicle window, when the vehicle window assembly is in the load running state. According to the current or speed, voltage or stroke, the first running data, i.e. the first characteristic curve, is generated.

[0078] In this embodiment, according to the national safety standard, the target load is selected, for example, 80N, and the entire lifting process of the vehicle window from the bottom to the top is controlled to maintain the target load applied to the vehicle window. In this process, the running current of the vehicle window assembly or the motor speed of the vehicle window assembly is collected, and the running voltage of the vehicle window assembly or the running stroke of the vehicle window is obtained. According to the collected data, the first characteristic curve in the lifting process of the vehicle window is drawn, so as to show the related display of the running parameters of the vehicle window in the full load lifting process through the first characteristic curve.

[0079] In combination Figure 4As shown, the X-axis is time, and the Y-axis is the operating current of the window assembly. Curve A corresponds to the relationship between the collected current and time during the process of the window assembly rising from the bottom to the top without additional load. Curve B corresponds to the relationship between the collected current and time during the process of the window assembly rising from the bottom to the top with the same load applied to the window assembly throughout the entire process. Comparing curve A and curve B, it can be seen that the operating current during the process of the window assembly rising without additional load is less than the operating current during the process of the window assembly rising with the target load. That is, the operating current increases when the window encounters an obstacle during the rising process. The target load applied to the window can be simulated by setting a weight in the rising path of the window. The specific value of the target load can be set according to national safety standards and calibrated to improve the stability and safety of the calibrated window anti-pinch function.

[0080] In an example, different voltage values are set by a voltage stabilizing power supply to simulate the working state of the window assembly under different power supply voltages. According to the detected voltage, current or motor speed during the process of the window rising, a characteristic curve of voltage and current or a characteristic curve of voltage and motor speed is generated.

[0081] In an example, according to the change of the stroke of the window rising, the change of the current or the motor speed during the rising process is recorded to generate a characteristic curve of stroke and current or a characteristic curve of stroke and motor speed.

[0082] Optionally, a sliding average curve of the first characteristic curve is obtained by using MATLAB to filter out the harmonics of the ripple. The sliding window is selected to be 2 times the period of the ripple. That is, if the period of the ripple is T, the size of the sliding window should be 2T. In this way, the harmonic components in the ripple can be effectively filtered out while the main trend of the curve is retained. By applying the sliding average, the influence of the harmonics can be reduced, thereby obtaining a more stable equivalent direct current component of the current to more accurately reflect the actual working state of the motor. Figure 5 As shown, the relationship curve of the current and the stroke of the window is shown, in which curve C is the curve before fitting, and curve C' is the curve after filtering fitting. As can be seen by comparison, by fitting and filtering the curve, the influence of the harmonics can be reduced, thereby improving the stability and accuracy of the curve.

[0083] Optionally, second operating data in a target load state of the window assembly is obtained. In the target load state of the window assembly at the target position, 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. According to the current or the speed, the voltage or the stroke, the second operating data, i.e., the second characteristic curve, is generated.

[0084] In this embodiment, an obstacle is set at a target position in the window lifting path, the window is controlled to start lifting, the running parameters in the lifting process are obtained, including current or motor speed, and voltage or window travel. And through the current or speed, voltage or travel, the second running data, that is, the second characteristic curve, is generated. Combined with the second characteristic curve, the changes of the running parameters when the window encounters an obstacle are shown. The target position can be selected from multiple positions, 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, and each target position can be tested and calibrated respectively, thereby improving the comprehensiveness of the calibrated position and the stability and safety of the anti-pinch function of the calibrated window.

[0085] In an example, the changes of the current or motor speed in the lifting process are recorded under different voltage conditions, the changes of the current with time are measured and recorded, and the second characteristic curve is formed.

[0086] In an example, according to the change of the window travel in the lifting process, the changes of the current or motor speed in the lifting process are recorded, and the second characteristic curve of the travel and the current or the second characteristic curve of the travel and the motor speed is generated.

[0087] Exemplarily, according to the national safety standard, the actual anti-pinch force corresponding to the triggering of the window anti-pinch function needs to be within the safety range to avoid injury to the user, and the safety range is 60N to 90N. In this example, multiple target positions are selected in the lifting path of the window, a target load is set for each target position, and 80N is taken as an example. The current or motor speed in the window lifting process and the voltage or window travel under different voltage conditions are obtained respectively, and the curve relationship between the running parameters in the window lifting process is formed. For example, the curve between the current and the voltage, the curve between the current and the window travel, the curve between the motor speed and the voltage, and the curve between the motor speed and the window travel. Through these curves, the changes of the running parameters in the window lifting process under different conditions can be seen, and the performance of the running parameters when the window encounters an obstacle can be shown.

[0088] It should be noted that in actual testing, the simulated target load is not limited to 80N, and can also be set to 60N, 70N, 85N or 90N. The loads that can meet the national safety standard can be tested and calibrated to improve the comprehensiveness of the testing and calibration. The simulated target load includes but is not limited to weights or other easily weighed objects.

[0089] Optionally, the step of obtaining a triggering threshold for triggering the window anti-pinch function based on 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 rotational 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, first and second operating data are acquired under the same operating conditions. A polynomial fit 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 corresponding to the intersection is the trigger threshold for 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 rising to prevent injury to passengers.

[0091] Optionally, the step of performing polynomial fitting on the second characteristic curve to obtain a smooth characteristic curve includes: using MATLAB's curve fitting toolbox (cftool), 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 conditions 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 conditions is good or the calibration accuracy requirements are 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 fitted second characteristic curve 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] Combine Figure 6 As shown, the X-axis is the window operating time, and the Y-axis is the operating current of the window assembly. 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 window hits an obstacle, the current will increase. Observing curves D and E', the current of curve E' increases during the window's rise and intersects with curve D. 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 block M is the operation curve of the process of the window rising to meet the obstacle, and the corresponding curve in block N is the operation parameter of the window assembly after the anti-pinch function is triggered. The trigger threshold value determined by the first characteristic curve and the second characteristic curve is further corrected by the dynamic correction and test method in the above embodiment, and the target trigger threshold value is finally obtained to improve the accuracy and comprehensiveness of the calibration of the window anti-pinch function, and further improve the stability and safety of the operation of the window anti-pinch function.

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

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

[0095] The configuration information includes: environment temperature and test environment humidity, so that the consistency and reliability of the test under different temperature and humidity can adapt to different environment temperature and humidity. Further, the test environment temperature and humidity can be changed by using a temperature and humidity simulation cabin and other equipment to evaluate the reliability of the window anti-pinch function under different environmental conditions.

[0096] The configuration information includes: test point. The number of test points is multiple, which determines the specific position of the window in the rising process that needs to be tested for anti-pinch force, so as to calibrate multiple positions of the window, and further improve the stability and safety of the operation of the anti-pinch function. Among them, in combination with Figure 3 As shown, for the window with a bent top, a test point b is arranged at the bending position, and multiple test points a and c are arranged on both sides of the bending position respectively, so as to improve the comprehensiveness and accuracy of the calibration of the anti-pinch function.

[0097] The configuration information includes an 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 tested that the anti-pinch function can work normally under different power supply conditions. Among them, by setting different voltage values through the stabilized power supply, the working state of the vehicle under different power supply voltages is simulated, so as to test the performance of the window anti-pinch function under these conditions.

[0098] The configuration information includes an operating stroke of the window. By configuring the operating stroke of the window, it is tested that the anti-pinch function can work normally under different window heights. Among them, the anti-pinch tester is adjusted to test at different target positions, so as to accurately test at different heights of the window.

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

[0100] In this embodiment, by using the calibration system for the window anti-pinch function provided in the present application, the accurate calibration of the trigger threshold of the anti-pinch function can be improved, and the maintenance and adjustment caused by the inaccuracy of the anti-pinch function can be reduced, thereby reducing the test cost in the early stage and the maintenance cost in the later stage. Moreover, the calibration method for the window anti-pinch function provided in the present application can be used to 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 testing in the related art, the test cost is reduced, and the test period is shortened. Moreover, the calibration method for the window anti-pinch function provided in the present application can be used as a standardized production process, and is applicable to different vehicles, thereby improving the production efficiency of the vehicle.

[0103] Optionally, the calibration general control module 710 further includes a window control simulation system. The window control simulation system is developed by using a software of a programming language such as Matlab or Python, and is configured to simulate behaviors of the window controller, so as to perform testing and calibration without the actual controller. The behaviors can be intuitively analyzed by using a plot function of Matlab.

[0104] Optionally, the data interaction module 720 uses a trace·snooper function of a trace32 debugger of Lauterbach to capture current data, and uses a python script tool to create a streaming file for trace32 analysis and log saving. A high-speed bus diagnosis device supporting CAN FD is used to collect and analyze vehicle network communication data. A network camera is used to record the working condition of the window, and to exclude external interference. The calibration general control module performs a window lifting request, and controls parameters related to window lifting in a program of the practice script of trace32 to complete the window control request action.

[0105] Optionally, the anti-pinch test instrument starts to collect actual anti-pinch force data. The anti-pinch test instrument and the trace32 data are transmitted by using a streaming file created by Python, and are time-synchronized according to system time, so as to be analyzed by the upper calibration general control module.

[0106] Optionally, the calibration system 700 further includes a programmable power supply and a temperature and humidity simulation bin.

The anti-pinch test instrument needs to be able to measure the anti-pinch force at different window heights, so as to ensure the consistency of the anti-pinch function in the entire stroke.
