[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The following describes a method and apparatus for measuring lateral offset after a vehicle collision test according to embodiments of this application, with reference to the accompanying drawings. Addressing the problems mentioned in the background art, this application provides a method for measuring lateral offset after a vehicle collision test. In this method, a preset test paper is pasted onto a target position on a preset stainless steel plate, and the test paper is folded and cut to obtain a first cut paper and a second cut paper corresponding to the test paper. An offset measuring device is constructed based on the first cut paper, the second cut paper, and the stainless steel plate. The offset measuring device is fixed to the ground in the reverse direction of the left front wheel of the vehicle under test, and the second cut paper is folded up to obtain the pre-collision wheel imprint in the first cut paper during the vehicle's reversal. The first cut paper is folded up, and the second cut paper is folded back to the ground to obtain the post-collision wheel imprint of the vehicle or moving barrier in the second cut paper after the collision test. Based on the pre-collision wheel imprint and the post-collision wheel imprint, the lateral offset of the vehicle under test after the collision test is calculated. This application determines whether a vehicle meets regulatory requirements by accurately measuring the offset of its collision position after an actual crash test, comparing it to the theoretical collision position. This solves the problem of existing technologies being unable to accurately measure the vehicle's offset after a crash test, making it difficult to determine whether a vehicle crash test meets regulatory requirements.

[0030] Specifically, Figure 1 This is a flowchart illustrating a method for measuring lateral offset after a vehicle collision test, as provided in an embodiment of this application.

[0031] like Figure 1 As shown, the method for measuring the lateral offset after a vehicle collision test includes the following steps:

[0032] In step S101, a preset test paper is pasted onto a preset target position on a stainless steel plate, and the test paper is folded and cut to obtain a first cut paper and a second cut paper corresponding to the test paper, so as to construct an offset measuring device based on the first cut paper, the second cut paper and the stainless steel plate.

[0033] In this embodiment, the test paper is first pasted in the middle of a stainless steel plate, and then folded and cut to obtain two cut sheets corresponding to the test paper, thereby constructing an offset measuring device, which provides reliable technical support for offset measurement in subsequent actual vehicle collision tests.

[0034] Optionally, in one embodiment of this application, the test paper is folded and cut to obtain a first cut paper and a second cut paper corresponding to the test paper, including: folding the test paper along a preset folding line and cutting the folded test paper along a preset cutting line to obtain the first cut paper and the second cut paper.

[0035] It should be noted that the main body of this embodiment can be made of a 460mm*360mm*0.1mm stainless steel plate, with an A3 white paper placed in the middle of the stainless steel plate. Figure 2 As shown, use double-sided tape to stick the white paper to the pasting area, and fold it along the fold line. Then cut the paper along the cutting line, as shown. Figure 3 As shown, two pieces of cut paper are obtained, namely the first cut paper and the second cut paper.

[0036] Therefore, the embodiments of this application construct an offset measuring device by folding and cutting paper and combining it with a stainless steel plate, thereby reducing the cost of offset measurement in actual collision tests and improving measurement efficiency and accuracy.

[0037] In step S102, the offset measuring device is fixed to the ground in the direction of the left front wheel of the vehicle under test moving backward, and the second cut paper is folded up to obtain the front wheel imprint of the vehicle under test in the first cut paper during the backward movement of the vehicle under test.

[0038] Furthermore, in the embodiments of this application, the aforementioned offset measuring device is fixed to the ground in the reverse direction of the left front wheel of the vehicle under test or the moving barrier, and the second cut paper is folded up to obtain the front wheel imprint in the first cut paper during the reverse process of the vehicle under test, providing reliable data guidance and basis for the offset measurement of subsequent actual collision tests.

[0039] Optionally, in one embodiment of this application, before fixing the offset measuring device to the ground in the reverse direction of the left front wheel of the vehicle under test, the method further includes: adjusting the vehicle under test or a preset moving barrier to a preset theoretical position and straightening the vehicle under test.

[0040] In actual implementation, the embodiments of this application first require adjusting the vehicle (or moving barrier) position to the theoretical T0 position so that, during the T0 camera view capture of the car crash test, the aforementioned offset measuring device is fixed to the ground in the reverse direction of the vehicle's left front wheel; secondly, the embodiments of this application require straightening the wheel (this straightening step is not required for moving barriers), and folding up the paper numbered P2 (i.e., the second cut paper), leaving the paper numbered P1 (i.e., the first cut paper) on the ground; then, the embodiments of this application can move the vehicle backward, at which point a wheel imprint with a lateral offset of 0 (i.e., the wheel imprint before the collision) is left on the paper numbered P1, such as... Figure 4 As shown.

[0041] Therefore, the embodiments of this application provide intuitive and reliable data for measuring the lateral offset of an actual collision by adjusting the position of the vehicle under test and obtaining the wheel imprints before the collision.

[0042] In step S103, the first cut paper is folded up and the second cut paper is folded back to the ground to obtain the post-collision wheel imprint of the test vehicle or moving barrier in the second cut paper after the collision test. Based on the pre-collision wheel imprint and the post-collision wheel imprint, the lateral displacement of the test vehicle after the collision test is calculated.

[0043] Furthermore, in an embodiment of this application, the P1 paper can be folded up and the second cut paper can be folded back to the ground to obtain the wheel imprint of the test vehicle in the P2 paper after the collision test, so as to calculate the lateral displacement of the test vehicle after the collision test.

[0044] Therefore, in the embodiments of this application, the offset measuring device does not need to be placed in the deformation area of ​​the collision during the collision test, and the offset of the actual car collision test can be accurately measured.

[0045] Optionally, in one embodiment of this application, the lateral offset of the vehicle under test after the collision test is calculated based on the wheel imprints before and after the collision, including: determining the initial lateral offset of the vehicle under test based on the wheel imprints before the collision; calculating the displacement difference between the wheel imprints before and after the collision; and determining the lateral offset of the vehicle under test after the collision test based on the displacement difference and the initial lateral offset.

[0046] As one possible approach, embodiments of this application can fold up paper with number P1 and leave paper with number P2 on the ground. After an actual collision occurs, the wheel will leave a wheel mark on paper with number P2 after passing over it, such as... Figure 5 As shown; subsequently, embodiments of this application can compare the difference ΔX between the wheel marks on the two sheets of paper, as... Figure 6 This allows for the determination of the actual lateral offset during the collision.

[0047] Therefore, in the embodiments of this application, after an actual vehicle collision test, the actual collision position is compared with the theoretical collision position to measure the specific value of the displacement of the collision position, thereby determining whether it meets the regulatory requirements.

[0048] According to the method for measuring lateral offset after a vehicle collision test proposed in this application, a preset test paper is pasted at a target position on a preset stainless steel plate. The test paper is then folded and cut to obtain a first cut paper and a second cut paper corresponding to the test paper. An offset measuring device is constructed based on the first cut paper, the second cut paper, and the stainless steel plate. The offset measuring device is fixed to the ground in the reverse direction of the left front wheel of the vehicle under test, and the second cut paper is folded up to obtain the pre-collision wheel imprint in the first cut paper during the reverse process of the vehicle under test. The first cut paper is folded up, and the second cut paper is folded back to the ground to obtain the post-collision wheel imprint of the vehicle under test or the moving barrier in the second cut paper after the collision test. Based on the pre-collision wheel imprint and the post-collision wheel imprint, the lateral offset of the vehicle under test after the collision test is calculated. This application accurately measures the specific value of the offset of the collision position by comparing it with the theoretical collision position after the actual vehicle collision test, thereby determining whether it meets the regulatory requirements.

[0049] Secondly, the measuring device for measuring lateral offset after a vehicle collision test according to an embodiment of this application is described with reference to the accompanying drawings.

[0052] The paper processing module 100 is used to paste a preset test paper onto a preset target position on a stainless steel plate, and to fold and cut the test paper to obtain a first cut paper and a second cut paper corresponding to the test paper, so as to construct an offset measuring device based on the first cut paper, the second cut paper and the stainless steel plate.

[0053] The test module 200 is used to fix the offset measuring device to the ground in the reverse direction of the left front wheel of the vehicle under test, and fold up the second cut paper to obtain the collision front wheel imprint in the first cut paper during the reverse process of the vehicle under test.

[0054] The calculation module 300 is used to fold up the first cut paper and fold the second cut paper back to the ground to obtain the post-collision wheel imprint of the test vehicle or moving barrier in the second cut paper after the collision test. Based on the pre-collision wheel imprint and the post-collision wheel imprint, the lateral displacement of the test vehicle after the collision test is calculated.

[0055] Optionally, in one embodiment of this application, the paper processing module 100 includes: a cutting unit, used to fold the test paper along a preset folding line and cut the folded test paper along a preset cutting line to obtain a first cut paper and a second cut paper.

[0056] Optionally, in one embodiment of this application, the vehicle collision test lateral offset measuring device 10 of this application embodiment further includes: a position adjustment module, used to adjust the vehicle under test or a preset moving barrier to a preset theoretical position before fixing the offset measuring device to the ground in the direction of the left front wheel of the vehicle under test, and to straighten the vehicle under test.

[0057] Optionally, in one embodiment of this application, the calculation module 300 includes: a first determining unit and a second determining unit.

[0058] The first determining unit is used to determine the initial lateral offset of the vehicle under test based on the wheel imprints before the collision.

[0059] The second determining unit is used to calculate the displacement difference between the wheel imprints before and after the collision, and to determine the lateral offset of the vehicle under test after the collision test based on the displacement difference and the initial lateral offset.
