Description

Technical Field

[0001] This application relates to the technical field of vehicle sunroof parameter calibration, and particularly to a method, device, equipment and readable storage medium for calibrating the reset times of a sunroof. Background Art

[0002] After long-term use of a vehicle sunroof, the position of the sunroof will shift to a certain extent, which will affect the sealing performance when closed and the smoothness of opening and closing. Performing a reset operation on the sunroof can recalibrate the position of the sunroof to ensure that it is completely closed and tightly gapless, so as to prevent rainwater leakage or external noise from entering the vehicle.

[0003] Usually, a Hall sensor is used to monitor the rotation of the sunroof motor. Each time the motor rotates one circle, a square wave signal is generated. By counting the number of square waves, the running times of the sunroof are indirectly calculated. When the running times of the sunroof reach the preset reset times, the sunroof reset is triggered. Currently, the preset reset times are often fixed values set based on experience. However, due to voltage fluctuations, such as when the voltage increases, the motor speed increases, and the displacement of the sunroof is greater under the same number of square waves; when the voltage decreases, the motor speed decreases, and the displacement of the sunroof is smaller under the same number of square waves. That is, there is a deviation between resetting the sunroof with fixed reset times and the actual displacement generated by the sunroof operation.

[0004] In order to improve the reliability of sunroof reset, a relatively small sunroof reset times is often calibrated based on experience. This leads to relatively frequent sunroof resets, which increases the mechanical structure loss of the sunroof, and when the sunroof is reset, the sunroof glass needs to rush forward a short distance, and users will mistakenly think that this is an unpredictable failure, thus generating complaints. That is, frequent sunroof resets will also reduce the user experience.

[0005] In summary, the relatively small sunroof reset times calibrated based on experience currently will lead to relatively frequent sunroof resets, which will increase the mechanical structure loss of the sunroof and reduce the user experience. Summary of the Invention

Furthermore, it can improve the calibration accuracy of the number of sunroof resets, thereby solving the problem of frequent sunroof resets caused by the relatively small number of sunroof resets calibrated by experience at present.

[0045] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0046] To make the purpose, technical solution and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0047] In a first aspect, an embodiment of this application provides a method for calibrating the reset times of a sunroof.

[0048] In one embodiment, referring to Figure 1 , Figure 1 is a schematic flowchart of an embodiment of the method for calibrating the reset times of the sunroof of this application. As shown in Figure 1 , the method for calibrating the reset times of the sunroof includes:

[0049] Step S10: Obtain the deviation of the sunroof position before and after multiple opening and closing tests, where each opening and closing test controls the sunroof to move from fully closed to fully open and then to fully closed.

[0050] In this embodiment, referring to Figure 2 , Figure 2 is a cross-sectional view of the sunroof of an embodiment of the method for calibrating the reset times of the sunroof of this application. As shown in Figure 2 , multiple opening and closing durability tests can be performed on the sunroof of the vehicle to be calibrated, and the deviation data of the sunroof position before and after multiple opening and closing tests can be measured during the durability test, so as to obtain the deviation data of the sunroof position before and after multiple opening and closing tests. To improve the reliability of calibrating the reset times of the sunroof, each opening and closing test controls the sunroof to move from fully closed to fully open and then to fully closed. Among them, the number of durability tests can be determined according to the required accuracy of calibration.

[0051] Step S20: Determine the maximum deviation of the sunroof position before and after one opening and closing test according to the deviation of the sunroof position before and after multiple opening and closing tests.

[0052] In this embodiment, the displacement of the sunroof during opening and closing is controlled by the motor. As described in the background art, due to voltage fluctuations, the displacement of the sunroof is different each time it is opened and closed. Therefore, through step S10, the sunroof of the vehicle to be calibrated is subjected to multiple opening and closing durability tests, and the deviation data of the sunroof position before and after multiple opening and closing tests are obtained through measurement. Furthermore, the maximum deviation of the sunroof position before and after a single opening and closing test is determined by synthesizing the deviations of the sunroof position before and after multiple opening and closing tests. Since the maximum deviation of the sunroof position before and after a single opening and closing test synthesizes the measurement data of the deviations of the sunroof position before and after multiple opening and closing tests, it can truly reflect the position deviation generated by the multiple operations of the sunroof, and can avoid the deviation of different sunroof displacements caused by changes in voltage. To improve the reliability of calibrating the sunroof reset times, the deviation data of the sunroof position before and after a single opening and closing test takes the maximum deviation.

[0053] Step S30: Obtain the maximum allowable position deviation of the sunroof, and determine the sunroof reset times according to the maximum allowable position deviation of the sunroof and the maximum deviation of the sunroof position before and after a single opening and closing test.

[0054] In this embodiment, the maximum allowable position deviation of the sunroof can be obtained from the sunroof manufacturer. The maximum allowable position deviation of the sunroof is the maximum value of the deviation between the actual closed position and the theoretical closed position of the sunroof that must be reset by the sunroof manufacturer. Its significance is that if the deviation between the actual closed position and the theoretical closed position of the sunroof reaches the maximum allowable position deviation of the sunroof after multiple operations and the sunroof is not reset, there will still be a large gap after the sunroof is fully closed, and there will be risks such as rain leakage in the sunroof. Each opening and closing operation of the sunroof will continuously accumulate displacement deviation. As the sunroof operates for a long time, when the accumulated displacement deviation reaches the maximum allowable position deviation of the sunroof, the sunroof should be reset. In step S20, the maximum deviation of the sunroof position before and after a single opening and closing test is determined. Therefore, according to the maximum allowable position deviation of the sunroof and the maximum deviation of the sunroof position before and after a single opening and closing test, the sunroof reset times can be determined.

[0055] In this embodiment, the vehicle sunroof to be calibrated can be subjected to multiple opening and closing durability tests. During the durability test, the deviation data of the sunroof position before and after multiple opening and closing tests are measured, so as to obtain the deviation data of the sunroof position before and after multiple opening and closing tests. Furthermore, the maximum deviation of the sunroof position before and after a single opening and closing test is determined by synthesizing the deviations of the sunroof position before and after multiple opening and closing tests. Since the maximum deviation of the sunroof position before and after a single opening and closing test synthesizes the measurement data of the sunroof position deviation before and after multiple opening and closing tests, it can truly reflect the position deviation generated by the multiple operations of the sunroof, and can avoid the deviation of different sunroof displacements caused by the change of voltage level. The maximum allowable position deviation of the sunroof can be obtained from the sunroof manufacturer. The maximum allowable position deviation of the sunroof is the maximum value of the deviation between the actual closed position and the theoretical closed position of the sunroof that must be reset as set by the sunroof manufacturer. Each opening and closing operation of the sunroof will continuously accumulate displacement deviation. Therefore, based on the maximum allowable position deviation of the sunroof and the maximum deviation of the sunroof position before and after a single opening and closing test, the reset times of the sunroof can be determined. Since the maximum deviation of the sunroof position before and after a single opening and closing test synthesizes the measurement data of the sunroof position deviation before and after multiple opening and closing tests, the accuracy of the determined reset times of the sunroof is higher, which can improve the calibration accuracy of the reset times of the sunroof, and thus can solve the problem of frequent sunroof reset caused by the relatively small reset times of the sunroof calibrated by experience currently.

[0056] Further, in one embodiment, referring to Figure 3 , Figure 3 is the detailed flowchart of step S10 in this application Figure 1 . As shown in Figure 3 , step S10 includes:

[0057] Step S101: Conduct the opening and closing test of the sunroof for the first preset number of times at the first preset temperature, conduct the opening and closing test of the sunroof for the second preset number of times at the second preset temperature, and conduct the opening and closing test of the sunroof for the third preset number of times at the third preset temperature. The first preset temperature is lower than the second preset temperature, and the first preset temperature is higher than the third preset temperature. The first preset number is greater than the second preset number, and the second preset number is greater than the third preset number;

[0058] Step S102: Measure the deviation of the sunroof position before and after each fourth preset number of opening and closing tests at different preset temperatures, where the first preset number, the second preset number, and the third preset number are all integer multiples of the fourth preset number;

[0059] Step S20 includes:

[0060] According to the deviation of the sunroof position before and after each fourth preset number of opening and closing tests at different preset temperatures and the proportion of the number of tests conducted at different preset temperatures to the total number of tests, the maximum deviation of the sunroof position before and after a single opening and closing test is calculated.

[0061] In this embodiment, for example, the first preset temperature is selected as the normal temperature of 23°C, the first preset number of times is selected as 6200 times, the second preset temperature is selected as the high temperature of 85°C, the second preset number of times is selected as 5100 times, the third preset temperature is selected as the low temperature of -20°C, and the third preset number of times is selected as 700 times. Specifically, 6200 opening and closing tests are performed on the sunroof at 23°C, 5100 opening and closing tests are performed on the sunroof at 85°C, and 700 opening and closing tests are performed on the sunroof at -20°C. In total, 12000 opening and closing durability tests are performed on the sunroof. Different numbers of opening and closing durability tests are carried out under different temperature conditions. This is because in reality, the situation of using the sunroof at 23°C throughout the year is the most frequent, and the number of times the sunroof is opened at low and high temperatures is less. Such a setting can more realistically simulate the actual usage conditions of users and better consider the influence of the temperature environment on the mechanical structure and electronic components, thereby ensuring the closest approximation of the test to the actual situation to the greatest extent. Refer to Figure 4 , Figure 4 is a schematic diagram for measuring the sunroof position deviation in an embodiment of the sunroof reset number calibration method of the present application. Figure 4 The distance a in Figure 4 represents the distance between the rangefinder and the sunroof glass. As

[0062] shown, using a rangefinder (such as an ultrasonic rangefinder and a laser rangefinder, etc.), the deviation of the sunroof position before and after each fourth preset number of opening and closing tests at different preset temperatures is measured. The fourth preset number of times is, for example, 100 times. Thus, the deviation data of the sunroof position before and after each 100 opening and closing tests at different preset temperatures as shown in Table 1 can be obtained. Since the number of opening and closing tests carried out at different temperatures is different, the number of deviation data of the sunroof position before and after each 100 opening and closing tests measured is different, and to better fit the actual situation, therefore, when calculating the maximum deviation of the sunroof position before and after a single opening and closing test, the proportion of the deviation data at different temperatures in the total data needs to be considered. Therefore, according to the deviation of the sunroof position before and after each fourth preset number of opening and closing tests at different preset temperatures and the proportion of the number of tests conducted at different preset temperatures to the total number of tests, the maximum deviation of the sunroof position before and after a single opening and closing test is calculated.

[0062] Table 1.

[0063] Test temperature Deviation of sunroof position before and after every 100 opening and closing tests Normal temperature (23°C) Δa1, Δa2, ……, Δa62 High temperature (85°C) Δb1, Δb2, ……, Δb51 Low temperature (-20°C) Δc1, Δc2, ……, Δc7

[0064] Further, in one embodiment, calculating the maximum deviation of the skylight position before and after a single opening and closing test based on the deviation of the skylight position before and after each fourth preset number of opening and closing tests at different preset temperatures and the proportion of the number of tests conducted at different preset temperatures to the total number of tests includes:

[0065] Based on the deviation of the skylight position before and after each fourth preset number of opening and closing tests at different preset temperatures and the proportion of the number of tests conducted at different preset temperatures to the total number of tests, the maximum deviation of the skylight position before and after a single opening and closing test is calculated through a formula, and the formula is:

[0066] Δ1 = [MAX(|Δa1|, |Δa2|, …, |Δan|) * times1 / (times1 + times2 + times3) + MAX(|Δb1|, |Δb2|, …, |Δbn|) * times2 / (times1 + times2 + times3) + MAX(|Δc1|, |Δc2|, …, |Δcn|) * times3 / (times1 + times2 + times3)] / times4;

[0067] Wherein, Δ1 is the maximum deviation of the skylight position before and after a single opening and closing test, (|Δa1|, |Δa2|, …, |Δan|) represents the absolute values of the deviations of the skylight position before and after each fourth preset number of opening and closing tests at the first preset temperature, (|Δb1|, |Δb2|, …, |Δbn|) represents the absolute values of the deviations of the skylight position before and after each fourth preset number of opening and closing tests at the second preset temperature, (|Δc1|, |Δc2|, …, |Δcn|) represents the absolute values of the deviations of the skylight position before and after each fourth preset number of opening and closing tests at the third preset temperature, times1 is the first preset number, times2 is the second preset number, times3 is the third preset number, and times4 is the fourth preset number.

[0068] In this embodiment, continue to take the example of conducting 6,200 opening and closing tests (times1) on the sunroof at room temperature of 23°C, 5,100 opening and closing tests (times2) on the sunroof at high temperature of 85°C, and 700 opening and closing tests (times3) on the sunroof at low temperature of -20°C, with a total of 12,000 opening and closing durability tests (times1 + times2 + times3) on the sunroof. And taking the data shown in Table 1 as an example, the above calculation formula can be further expressed as Δ1 = [MAX(|Δa1|, |Δa2|, …, |Δa62|) * 6,200 / (12,000) + MAX(|Δb1|, |Δb2|, …, |Δb51|) * 5,100 / (12,000) + MAX(|Δc1|, |Δc2|, …, |Δc7|) * 700 / (12,000)] / 100. By comprehensively considering the maximum deviations of the sunroof position before and after multiple every 100 opening and closing tests at different temperatures through the above formula, the maximum deviation of the sunroof position before and after a single opening and closing test can be accurately calculated, thereby improving the calibration accuracy of the sunroof reset times, and solving the problem of frequent sunroof reset caused by the relatively small sunroof reset times calibrated by experience currently.

[0069] Further, in one embodiment, step S30 includes:

[0070] Divide the maximum allowable position deviation of the sunroof by the maximum deviation of the sunroof position before and after a single opening and closing test, and take the integer of the obtained quotient to get the sunroof reset times.

[0071] In this embodiment, specifically, the sunroof reset times can be calculated according to the maximum allowable position deviation of the sunroof and the maximum deviation of the sunroof position before and after a single opening and closing test through the formula N = INT(Δ2 / Δ1), where N is the sunroof reset times, Δ2 is the maximum allowable position deviation of the sunroof, Δ1 is the maximum deviation of the sunroof position before and after a single opening and closing test, and INT(x) represents taking the integer of x.

[0072] Further, in one embodiment, the sliding assembly of the sunroof for conducting the opening and closing test is treated with ash spreading.

[0073] In this embodiment, to improve the stability of the sunroof operation, better simulate the operation of the sunroof guide rail in a real environment, and considering that the dust resistance of the sunroof guide rail also affects the displacement during the opening and closing of the sunroof, before conducting the opening and closing test on the sunroof to be calibrated, ash can be scattered on the sliding components on both the left and right sides of the sunroof. The sliding components of the sunroof where ash is scattered mainly include the guide rail of the sunroof, and may also include other mechanical components. Arizona ash can be scattered. Specifically, 3g of Arizona ash can be scattered on each of the left and right sides of the sunroof, and a total of 2g of Arizona ash can be scattered on the mechanical components and the guide rail on each side. By scattering ash, the deviation between the measured position of the sunroof in the sunroof opening and closing durability test and the real environment can be reduced, thereby improving the calibration accuracy of the sunroof reset times.

[0074] Further, in one embodiment, after step S30, it includes:

[0075] During the actual operation of the sunroof, count the number of operations of the sunroof;

[0076] When the number of operations of the sunroof reaches the sunroof reset times, control the sunroof to reset.

[0077] In this embodiment, steps S10 - S30 are used to calibrate the sunroof reset times of the sunroof to be calibrated. After calibration, for the same type of sunroof, during its subsequent actual operation, the number of operations of the sunroof can be counted in real time. For example, the process from fully open (or half open) to fully closed (or half closed) of the sunroof can be counted as one operation of the sunroof, which can be set according to specific needs. When the counted number of operations of the sunroof reaches the sunroof reset times, control the sunroof to reset. After reset, when the sunroof performs a closing operation subsequently, it can be fully closed and tightly sealed without gaps, preventing rainwater leakage or external noise from entering the vehicle.

[0078] In a second aspect, the embodiments of the present application also provide a device for calibrating the sunroof reset times.

[0079] In one embodiment, referring to Figure 5 , Figure 5 is a schematic diagram of the functional modules of an embodiment of the device for calibrating the sunroof reset times of the present application. As Figure 5 shown, the device for calibrating the sunroof reset times includes:

[0086] The first determination module 20 includes:

[0087] The first determination unit is configured to calculate the maximum deviation of the sunroof position before and after a single opening and closing test according to the deviation of the sunroof position before and after each fourth preset number of opening and closing tests at different preset temperatures and the proportion of the number of tests performed at different preset temperatures in the total number of tests.
