Description

Technical Field

[0001] The present invention relates to the technical field of vehicle testing, and in particular to a method, system, equipment and medium for detecting inertial load of a vehicle door lock. Background Art

[0002] The national standard has made relevant provisions for automobile door locks. The standard number is GB15086-2013, "Performance Requirements and Test Methods for Automobile Door Locks and Door Retainers". It stipulates that the minimum inertial load resistance applied to the door locks in a specific direction when the car collides can cause the parts to open, and the combined inertial load resistance that prevents unlocking. It should ensure that the door lock system (correctly installed on the door) remains in the locked position when it is subjected to an inertial load of 30g in the test direction to ensure that the door will not open by itself when the car collides.

[0003] Although the real vehicle collision test can provide intuitive test results, its high equipment and operation costs, as well as the characteristics that are difficult to accurately quantify and control, make this method less than ideal in terms of cost-effectiveness. The real vehicle collision test not only requires large-scale professional equipment and venues, but also requires a professional operation team to ensure the accuracy and safety of the test. In addition, due to the complexity and unpredictability of the test, its results are difficult to accurately quantify, which to a certain extent limits its application in the evaluation of the inertia protection function of door locks; at the same time, although the door lock bench test has the advantages of low cost and high efficiency, its limitations are also obvious. Since the bench test installs the external handle assembly on a special equipment, it cannot fully simulate the actual installation state of the door lock on the vehicle and the interaction with other structures. Therefore, its test results often deviate from the actual situation. This deviation may lead to inaccurate evaluation of the inertia protection function of the door lock, thereby affecting the safety performance of the vehicle. Summary of the invention

[0049] like Figure 1-Figure 7 As shown, the present invention proposes a vehicle door lock inertial load detection method, system, device and medium.

[0050] In an exemplary embodiment, a vehicle door lock inertial load detection method includes:

[0051] Determining each test collision height based on a first mapping relationship between a theoretical lateral load and a theoretical collision height and each test lateral load selected during the test;

[0052] Determining each test lateral acceleration based on a second mapping relationship between a theoretical collision height and a theoretical lateral acceleration and each test collision height;

[0053] The minimum lateral acceleration that triggers the anti-inertia protection is determined as the target lateral acceleration according to each test lateral acceleration.

[0054] In this embodiment, before the collision test begins, it is necessary to select a load range to be applied to the vehicle door. For example, the national standard stipulates an acceleration of 30g. In order to determine the minimum acceleration that triggers the door lock's inertia protection, this application selects a load range that includes 30g. After determining the relationship between the theoretical lateral load and the theoretical collision height, the selected lateral load value is used to calculate the collision height required to reach this load, thereby determining whether the door lock has triggered the inertia protection, until the test obtains an accurate value.

[0055] Exemplarily, the load range in this embodiment is selected as 5g to 85g.

[0056] Exemplarily, in this embodiment, the first mapping relationship between the theoretical lateral load and the theoretical collision height is given by the law of conservation of energy:

[0057]

[0058] Where m is the mass of sphere 103, g is the acceleration of gravity, h is the collision height of sphere 103, and v is the collision velocity. It can be seen that:

[0059]

[0060] At the moment when the ball 103 hits the side door assembly 3, the impact force of the ball 103 on the side door will generate acceleration a. According to Newton's second law, the relationship between acceleration a, force F and ball mass m is F=ma. Since the force F during the collision is proportional to the acceleration a at the moment of collision, it can be obtained that:

[0061]

[0062] Among them, t is the collision time, so that the first mapping relationship between the theoretical lateral load and the theoretical collision height can be finally obtained:

[0063]

[0064] Therefore, when the mass m of the sphere 103 is constant, the acceleration a at the moment of collision is nonlinearly related to the collision height h of the sphere 103 (the acceleration a at the moment of collision is linearly related to the square root of the collision height h of the sphere 103), and is inversely proportional to the collision action time t. In actual collision tests, the collision action time t is concentrated around 200ms. This data can also be obtained through test collection and analysis. When there is enough data, the collision time is taken as 200ms. Figure 5-Figure 7As shown, by intercepting the impact test signals under three different accelerations, we clearly observe that the action time when the ball 103 collides with the side door assembly 3 is about 200ms.

[0065] It is worth noting that, through further analysis, when the mass m of the sphere 103 is constant, there is a significant proportional relationship between the acceleration a at the moment of collision and the square root of the collision height h of the sphere 103. The lateral load in this embodiment corresponds to the acceleration a, and each test collision height can be calculated by the target load selected in the load range and the above-mentioned corresponding relationship. The designated points of the door are collided with each other through the obtained test collision heights, and after the actual test lateral acceleration is obtained, the lateral acceleration when the door inertia resistance protection is triggered is the target lateral acceleration.

[0066] In an exemplary embodiment, determining each test lateral acceleration based on the second mapping relationship between the theoretical collision height and the theoretical lateral acceleration and each test collision height includes:

[0067] Acquire each detected lateral acceleration received by the vehicle door at each test collision height, and establish a third mapping relationship between the test collision height and the detected lateral acceleration;

[0068] Comparing the third mapping relationship with the second mapping relationship to determine a deviation;

[0069] If the deviation is less than the preset deviation value, each test lateral acceleration is determined according to the third mapping relationship and each test collision height.

[0070] In this embodiment, after the first mapping relationship between the theoretical lateral load and the theoretical collision height is obtained as described above, the first mapping relationship needs to be verified to determine whether the relationship between the actual lateral acceleration and the actual collision height is consistent with the theoretical first mapping relationship, so as to avoid errors that are too large and lead to errors in the theoretically derived mapping relationship.

[0071] The specific method is:

[0072] S100: According to the design requirements of the door lock inertia protection, take half of the minimum design requirement value, that is, 15g as the maximum calibration test impact acceleration;

[0073] S110: Divide the acceleration of 15g into 5 groups, namely 3g, 6g, 9g, 12g, and 15g, and calculate the corresponding theoretical collision height h of the sphere 103 through the first mapping relationship. b1 、h b2 、h b3 、h b4 、h b5 ;

[0074] S120: Ensure that the collision ball 103 is in a stationary state and is in contact with the designated point B of the door 1 coincide;

[0075] S130: Raise the spheres 103 to a theoretical height h b1 、h b2 、h b3 、h b4 、h b5 , and remain still for 5 seconds, then release and let the ball 103 fall freely, and the ball 103 hits B 1 Points;

[0076] S140: During the impact of the ball 103, signals of the acceleration sensors at the first impact point 301 and the second impact point 302 on the outside handle assembly 4 are collected and recorded, and at the same time, whether the vehicle door and the door lock mechanism are opened after the impact;

[0077] S150: Repeat the above experiment three times to obtain three sets of data and perform inspection, filtering and other processing to improve data quality;

[0078] S160: The maximum value of the Y-axis acceleration is averaged, and the value of the theoretical collision height of the sphere 103 and the measurement point P is obtained through data fitting. 1 , P 2 The relationship between the lateral acceleration of the test collision height and the detected lateral acceleration can be obtained as follows:

[0079]

[0080] Among them, k 1 With k 2 is the coefficient, b 1 With b 2 is the intercept.

[0081] In step S160 , since the error between the detected lateral acceleration at the theoretical collision height and the theoretical lateral acceleration is within the allowable error range, the third mapping relationship obtained in the actual collision test process can be consistent with the theoretically obtained first mapping relationship.

[0082] After the third mapping relationship is obtained, since the third mapping relationship is obtained through actual measurement, it is more representative and can more accurately reflect the relationship between the lateral acceleration and the collision height. Therefore, the third mapping relationship is used in the calculation.

[0083] It is worth noting that in this embodiment, professional software can also be used for data processing to obtain a nonlinear calibration relationship between the collision acceleration a of the sphere 103 and the collision height h of the sphere 103 .

[0084] In an exemplary embodiment, based on a first mapping relationship between a theoretical lateral acceleration and a theoretical collision height, after determining each required collision height of the vehicle door according to the first mapping relationship and each required lateral acceleration, the method further includes:

[0085] Select a test range of the lateral load, and use the minimum value of the test range as the first test lateral load;

[0086] Starting from the first test lateral load, each lateral load of the first preset value is used as the test lateral load.

[0087] Exemplarily, in this embodiment, the minimum lateral acceleration that triggers the anti-inertia protection is determined as the target lateral acceleration according to each tested lateral acceleration, including:

[0088] Determine a target lateral load interval for triggering the inertia resistance protection, and select the minimum lateral load in the target lateral load interval as the target lateral load;

[0089] The target lateral acceleration is determined according to the target lateral load range and the third mapping relationship.

[0090] The specific steps are as follows:

[0091] S200: The test interval range is selected as 5g to 85g, 5g is used as the first test lateral load, and the interval of 5g is used as the first preset value, and the test collision height h of the sphere 103 corresponding to each increase of 5g in the range of 5g to 85g is calculated according to the third mapping relationship i ;

[0092] S210: Setting three test impact points T on the outer side of the right front door assembly 3 1 , T 2 , T 3 ;

[0093] S220: adjusting the collision device and the test vehicle to ensure that the center point of the sphere 103 coincides with the center point of the predetermined test impact point T1 in a stationary state;

[0094] S230: Starting from the theoretical collision height corresponding to 5g, the sphere 103 is pulled to a predetermined theoretical height, kept still for 5 seconds and then released, the acceleration data of the two measuring points are recorded, and it is observed whether the door inertia protection is triggered;

[0095] S240: Repeat steps S210-S230 until the side door cannot be opened outwards, and detect whether the locking mechanism 405 of the outer handle assembly 4 is engaged, and determine the target load range of the minimum lateral acceleration that triggers the door lock anti-inertia protection function.

[0096] In an exemplary embodiment, determining the target lateral acceleration according to the target lateral load interval and the third mapping relationship includes:

[0097] Selecting a target lateral load interval, and taking the minimum value of the target lateral load interval as the second test lateral load;

[0098] Starting from the second lateral load, the lateral load at intervals of the second preset value is used as the test lateral load;

[0099] A target lateral load value for triggering the anti-inertia protection is determined, and a target lateral acceleration is determined according to the target lateral load value and a third mapping relationship.

[0100] Specific implementation steps:

[0101] S300: In the target lateral load range, the minimum lateral load value is used as the second test lateral load, and the theoretical collision height h is recalculated with a smaller acceleration increment (a second preset value, such as 1g). j ;

[0102] S310: Repeat steps S210-S230, but use h j As the new drop height, until a more accurate triggering minimum lateral acceleration a is obtained 1 .

[0103] S320: For T 2 and T 3 Repeat steps S300-S310 at the impact point to obtain a 2 and a 3 ;

[0104] S330: Take a 1 、a 2 、a 3 The minimum value among the three is taken as the minimum lateral acceleration afr for triggering the inertia protection of the side door lock;

[0105] S340: Similarly, according to the above test method, the acceleration data of the right rear, left front, and left rear side doors are collected to obtain a rr 、a fl 、a rl Minimum lateral acceleration for which the anti-inertia protection of the respective side door lock is triggered.

[0106] Exemplarily, if the target lateral load range is 41g to 45g, and the second test lateral load is 41g, the theoretical collision height corresponding to 41g is calculated according to the third mapping relationship, and then measurements are performed at 42g, 43g, 44g, and 45g in sequence, one of which is the minimum lateral acceleration required.

[0109] The side door assembly 3 is installed on the vehicle 2 and is located between the support rods 101. A collision point is provided on the side door assembly 3, and the collision point corresponds to the center of the sphere 103 when the sphere 103 is in a naturally vertical state.

[0110] In this embodiment, the position of the ball 103 that finally collides with the vehicle door can be adjusted by adjusting the position of the collision device, so that the minimum acceleration corresponding to each side door can be conveniently tested.

[0111] Exemplarily, in this embodiment, one collision point may be set, or multiple collision points may be set, for example, three collision points, namely the first collision point 301, the second collision point 302 and the third collision point 303, to increase the data of the experimental samples and improve the accuracy of the measurement results.
