The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0029] The following describes a method and device for measuring the lateral offset of a vehicle after a collision test according to an embodiment of the present application with reference to the accompanying drawings. In view of the problems mentioned in the above background technology, the present application provides a method for measuring the lateral offset of a vehicle after a collision test, in which a preset test paper is pasted at a target position of 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, so as to construct an offset measuring device according to the first cut paper, the second cut paper and the stainless steel plate; the offset measuring device is fixed to the ground in the backward direction of the left front wheel of the vehicle to be tested, and the second cut paper is folded to obtain the wheel mark before collision in the first cut paper during the backward process of the vehicle to be tested; the first cut paper is folded, and the second cut paper is folded back to the ground to obtain the wheel mark after collision of the vehicle to be tested or the mobile barrier in the second cut paper after the collision test is started, and the lateral offset of the vehicle to be tested after the collision test is calculated based on the wheel mark before collision and the wheel mark after collision. This application compares the actual collision position of the car with the theoretical collision position after the actual collision test to accurately measure the specific value of the offset of the collision position, so as to determine whether it meets the regulatory requirements. This solves the problem that the existing technology cannot accurately measure the offset of the vehicle after the collision test, and it is difficult to determine whether the vehicle collision test meets the regulatory requirements.
[0030] Specifically, Figure 1 A flow chart of a method for measuring the lateral offset of a vehicle after a collision test provided in an embodiment of the present application.
[0031] like Figure 1 As shown, the method for measuring the lateral offset of the vehicle after the collision test includes the following steps:
[0032] In step S101, a preset test paper is pasted at a target position of 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, so as to construct an offset measurement device according to the first cut paper, the second cut paper and the stainless steel plate.
[0033] The embodiment of the present application can firstly stick the test paper in the middle of the stainless steel plate, and fold and cut the test paper to obtain two cut papers corresponding to the test paper, thereby constructing an offset measurement device, which provides reliable technical support for the offset measurement of subsequent actual automobile collision tests.
[0034] Optionally, in one embodiment of the present 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 a first cut paper and a second cut paper.
[0035] It should be noted that the main body of the embodiment of the present application can be made of a 460mm*360mm*0.1mm stainless steel plate, and a piece of A3 white paper is placed in the middle of the stainless steel plate. Figure 2 As shown, use double-sided tape to stick the white paper in the pasting area, fold it at the folding line, and then cut the paper at the cutting line, as shown in the figure. Figure 3 As shown, two cut sheets of paper are obtained, namely a first cut sheet of paper and a second cut sheet of paper.
[0036] Therefore, the embodiment of the present application constructs an offset measurement device by folding and cutting paper and combining it with a stainless steel plate, thereby reducing the cost of offset measurement in an actual collision test and improving measurement efficiency and accuracy.
[0037] In step S102, the offset measuring device is fixed to the ground in the backward direction of the left front wheel of the vehicle to be tested, and the second cut paper is folded to obtain the wheel mark before collision in the first cut paper during the backward process of the vehicle to be tested.
[0038] Furthermore, the embodiments of the present application also require that the above-constructed offset measuring device be fixed to the ground in the rearward direction of the left front wheel of the vehicle to be tested or the mobile barrier, and the second cut paper be folded up to obtain the pre-collision wheel mark in the first cut paper during the rearward process of the vehicle to be tested, thereby providing reliable data guidance and basis for the offset measurement of subsequent actual collision tests.
[0039] Optionally, in one embodiment of the present application, before fixing the offset measuring device to the ground in the backward direction of the left front wheel of the vehicle to be tested, it also includes: adjusting the vehicle to be tested or a preset moving barrier to a preset theoretical position, and straightening the vehicle to be tested.
[0040] In the actual implementation process, the embodiment of the present application first needs to adjust the position of the vehicle (or mobile barrier) to the theoretical T0 position, so that during the T0 camera angle capture process of the automobile collision test, the offset measurement device constructed above is fixed to the ground in the backward direction of the left front wheel of the vehicle; secondly, the embodiment of the present application needs to correct the wheel (the mobile barrier does not require this correction step), and fold up the paper numbered P2 (i.e., the second cut paper), and leave the paper numbered P1 (i.e., the first cut paper) on the ground; thereafter, the embodiment of the present application can move the vehicle backward, leaving a wheel mark with a lateral offset of 0 on the paper numbered P1 (i.e., the wheel mark before the collision), such as Figure 4 shown.
[0041] Therefore, the embodiments of the present application provide an intuitive and reliable data basis for the determination of the lateral offset of an actual collision by adjusting the position of the vehicle to be tested and obtaining the wheel mark 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 mark of the vehicle to be tested or the mobile barrier in the second cut paper after the collision test is started, and the lateral displacement of the vehicle to be tested after the collision test is calculated based on the wheel mark before and after the collision.
[0043] Furthermore, the embodiment of the present application can fold up the P1 paper and fold the second cut paper back to the ground to obtain the post-collision wheel mark of the vehicle to be tested in the P2 paper after starting the collision test, so as to calculate the lateral offset of the vehicle to be tested after the collision test.
[0044] Therefore, during the collision test, the embodiment of the present application can accurately measure the offset of the actual collision test of the car without placing the offset measurement device in the deformation area of the collision.
[0045] Optionally, in one embodiment of the present application, based on the wheel mark before collision and the wheel mark after collision, the lateral offset of the vehicle to be tested after the collision test is calculated, including: determining the initial lateral offset of the vehicle to be tested according to the wheel mark before collision; calculating the displacement difference between the wheel mark before collision and the wheel mark after collision, and determining the lateral offset of the vehicle to be tested after the collision test according to the displacement difference and the initial lateral offset.
[0046] As a feasible method, in the embodiment of the present application, the paper numbered P1 can be folded up, and the paper numbered P2 can be left on the ground. After the actual collision occurs, after the wheel passes through the paper numbered P2, the wheel mark of the actual collision will be left on the paper numbered P2, such as Figure 5 As shown; then, the embodiment of the present application can compare the difference ΔX of the wheel marks on the two pieces of paper, such as Figure 6 As described above, the lateral offset of the actual collision is determined.
[0047] Therefore, after the actual collision test of the automobile, the embodiment of the present application compares the collision position with the theoretical collision position, thereby measuring the specific value of the offset of the collision position to determine whether it meets the regulatory requirements.
[0048] According to the method for measuring the lateral offset of a vehicle after a collision test proposed in an embodiment of the present application, a preset test paper is pasted at a preset target position of 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 according to the first cut paper, the second cut paper and the stainless steel plate; the offset measuring device is fixed to the ground in the backward direction of the left front wheel of the vehicle to be tested, and the second cut paper is folded to obtain the wheel mark before the collision in the first cut paper during the backward process of the vehicle to be tested; the first cut paper is folded, and the second cut paper is folded back to the ground to obtain the wheel mark after the collision of the vehicle to be tested or the mobile barrier in the second cut paper after the collision test is started, and the lateral offset of the vehicle to be tested after the collision test is calculated based on the wheel mark before the collision and the wheel mark after the collision. The present application compares the specific value of the offset of the collision position with the theoretical collision position after the actual collision test of the automobile, so as to determine whether it meets the regulatory requirements.
[0049] Next, a device for measuring the lateral displacement of a vehicle after a collision test according to an embodiment of the present application is described with reference to the accompanying drawings.

[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 mark of the vehicle to be tested or the mobile barrier in the second cut paper after starting the collision test, and calculate the lateral displacement of the vehicle to be tested after the collision test based on the pre-collision wheel mark and the post-collision wheel mark.
[0055] Optionally, in one embodiment of the present application, the paper processing module 100 includes: a cutting unit, configured 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.
