[0002] Automobile autonomous driving is the future trend, and ADAS (Advanced Driving Assistance System) is the only way for automobiles to achieve autonomous driving. At first, ADAS technology was applied to luxury cars. Due to the gradual maturity of technology and the trend of decreasing product prices, automobile manufacturers have gradually penetrated into mid-range cars and small cars. It is estimated that in the future, the number of automobiles equipped with ADAS technology globally will be extremely large.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0092] In the related art, the method for calibrating the longitudinal center line of an automobile by an existing calibration device is as follows:

[0093] (1) Move the calibration device and visually align the laser emitted from the center of the calibration device with the center of the front bumper of the automobile. In this method, initially visually align the laser emitted from the center of the calibration device with the center of the front bumper of the automobile. The calibration device is not in a vertical state with the longitudinal center plane of the vehicle, resulting in the laser point reflected back through the rearview mirror being biased towards the inside or outside of the laser scale plate of the laser device. It is difficult to find the reflected laser point on the laser scale plates on both sides of the vehicle, and there is an angular deviation in the left-right direction.

[0094] (2) Use a tape measure or a laser rangefinder to measure the distance between the calibration device and the front bumper or the center of the front wheels of the vehicle. This method ignores the uneven ground and the situation where the vehicle chassis suspension system is not adjusted. The rear axle of the vehicle's rear wheels and the cross beam of the calibration device are not on the same horizontal plane, resulting in different emission directions of the laser points on both sides and an angular deviation in the up-down direction.

[0095] (3) Install two wheel clamps on the rear wheels on both sides of the vehicle respectively, install lasers respectively, and then turn on the lasers for calibration. Due to the angular deviation in two directions, the laser points returned from both sides of the vehicle cannot effectively hit the laser scale plate. In order to make the laser points, after being reflected by the mirror, hit the scales on the laser scale plates on both sides equally, the operator needs to make multiple adjustments to the calibration device and the laser between the calibration device and the rear wheels on both sides of the automobile, resulting in a complex operation process, a high learning cost, and a reduced efficiency.

[0096] (4) Rotate the laser and adjust the irradiation direction of the laser spot so that the laser spot irradiates on the scale plates on both sides of the crossbeam of the calibration device. Adjust the calibration device until the scales of the laser spots on both sides of the crossbeam are equal. In this method, there is a certain distance between the calibration device and the rear wheels of the vehicle, which is not convenient for observing whether the scales of the laser spots on both sides are aligned with the scales on the laser, increasing the difficulty of calibration and the time cost.

[0097] The vehicle centering device and vehicle calibration device according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0098] Refer to Figures 1 to 5 As shown, the vehicle centering device according to the embodiment of the present invention includes a base 10, a first laser 20, two wheel positioning members 30, and a linkage mechanism 40.

[0099] Specifically, the first laser 20 is provided on the base 10 for emitting a laser beam 201 extending along the longitudinal direction of the vehicle, and the first laser 20 can be fixed on the base 10. The two wheel positioning members 30 are relatively provided on the base 10 and are symmetric about the laser beam 201 for positioning two relatively opposite wheels 60 of the vehicle in the transverse direction. For example, the two wheel positioning members 30 respectively position two front wheels of the vehicle.

[0100] The linkage mechanism 40 is provided between the two wheel positioning members 30 to enable the two wheel positioning components to move synchronously towards or away from each other in the transverse direction of the vehicle relative to the base 10. That is to say, both of the two wheel positioning members 30 can move relative to the base 10, and the two wheel positioning members 30 move towards or away from each other in the transverse direction of the vehicle. The linkage mechanism 40 is connected between the two wheel positioning members 30. When one wheel positioning member 30 moves a predetermined distance, through the linkage action of the linkage mechanism 40, the other wheel positioning member 30 can move the same distance, thereby realizing the synchronous movement of the two wheel positioning members 30.

[0101] Since the two wheel positioning members 30 are symmetric about the laser beam 201 emitted by the first laser 20, the laser beam 201 of the first laser 20 is at the midpoint position of the line connecting the two wheel positioning members 30. And when the two wheel positioning members 30 move relative to the base 10, the first laser 20 remains stationary, and the position of the laser beam 201 emitted by the first laser 20 remains unchanged. Thus, when the two wheel positioning members 30 are positioned on two relatively opposite wheels 60, the midpoint of the line connecting the two wheel positioning members 30 coincides with the midpoint of the line connecting the two relatively opposite wheels 60, and then the laser beam 201 emitted by the first laser 20 can be on the longitudinal center line of the vehicle.

[0102] According to the vehicle centering device provided by the embodiment of the present invention, the linkage mechanism 40 is used to drive the two wheel positioning members 30 to move relatively at the same time to position the two opposite wheels 60 in the lateral direction of the vehicle, so that after positioning the two wheels 60 in the lateral direction of the vehicle, the first laser 20 can be located at the central position between the two opposite wheels in the lateral direction of the vehicle, so that the laser beam emitted by the first laser 20 along the longitudinal direction of the vehicle can realize the calibration of the longitudinal center line of the vehicle. Its operation is simple and convenient, improving the calibration efficiency, and the calibration is accurate and reliable.

[0103] Refer to Figures 1 to 5 As shown, in an embodiment of the present invention, the wheel positioning member 30 includes a sliding plate 301, a wheel surface positioning member 302 and a wheel side positioning member 303. Among them, the sliding plate 301 is slidably arranged on the base 10 along the lateral direction of the vehicle. The wheel surface positioning member 302 is arranged on the sliding plate 301 for stopping and positioning the wheel surface of the wheel 60. The wheel side positioning member 303 is arranged on the sliding plate 301 for stopping and positioning the outer side surface of the wheel 60.

[0104] That is to say, the sliding plate 301 can slide relative to the base 10 in the lateral direction of the vehicle. The wheel surface positioning member 302 and the wheel side positioning member 303 are both arranged on the sliding plate 301 and can adjust their positions as the sliding plate 301 slides. Among them, the wheel surface positioning member 302 is used to position the wheel surface of the wheel 60, and the wheel side positioning member 303 is used to position the outer side surface of the wheel 60. During specific positioning, the vehicle centering device can be placed under the vehicle bottom, and then by moving the sliding plates 301 of the two wheel positioning members 30 along the lateral direction of the vehicle, the wheel surface positioning members 302 of the two wheel positioning members 30 are abutted against the wheel surfaces of the wheels 60, and the two wheel side positioning members 303 are abutted against the outer side surfaces of the wheels 60. In this way, the two wheel positioning members 30 can be respectively positioned on the two opposite wheels 60.

[0105] In this embodiment, the sliding plate 301 is used for sliding, which is convenient for the two wheel positioning members 30 to move towards each other or move in the opposite direction, and adjust the distance between the two wheel positioning members 30 to be consistent with the width of the two opposite wheels 60, so as to position the two opposite wheels 60. In addition, in the wheel positioning member 30, the wheel surface positioning member 302 is abutted against the wheel surface of the wheel 60, and the wheel side positioning member 303 is abutted against the side surface of the wheel 60. In this way, the wheel 60 is positioned from two directions, which can ensure reliable and accurate positioning of the wheel 60 and prevent the problem that the calibration of the vehicle center line is inaccurate due to inaccurate positioning of the wheel 60.

[0106] Exemplarily, a slider is provided at the bottom of the sliding plate 301, and a guide rail extending along the vehicle transverse direction is provided on the base 10. The slider is slidably engaged with the guide rail. In this way, the sliding plate 301 can slide smoothly and reliably in the vehicle transverse direction by the sliding engagement of the slider and the guide rail on the base 10.

[0107] Referring Figures 1 to 2 and Figure 5 As shown, in an embodiment of the present invention, the wheel positioning member 30 further includes a first locking member 307. The first locking member 307 is provided between the base 10 and the sliding plate 301 for relatively locking and fixing the sliding plate 301 and the base 10.

[0108] During the process of positioning the wheel 60, when the sliding plate 301 slides to the required position such that the wheel surface positioning member 302 abuts against the wheel surface of the wheel 60 and the wheel side positioning member 303 abuts against the side surface of the wheel 60, the sliding plate 301 and the base 10 are relatively locked and fixed by the first locking member 307. In this way, the problem of inaccurate positioning caused by the sliding of the sliding plate 301 after positioning can be prevented, ensuring reliable positioning.

[0109] It should be noted that the wheel positioning member 30 can move relative to the base 10, and the wheel positioning member 30 can be locked at different positions on the base 10 through the first locking member 307. In other words, the wheel positioning member 30 can randomly stop at a certain position on the base 10. Therefore, when positioning the wheel for vehicles with different widths, the positions where the wheel positioning member 30 stops are different. Furthermore, the position adjustment can be adapted to different vehicle models, and the calibration of the vehicle longitudinal center line for different vehicle models can be achieved.

[0110] Exemplarily, the first locking member 307 includes a screw rod and an operation knob 3071 provided at the upper end of the screw rod. A strip-shaped hole 3011 is provided on the sliding plate 301, and a threaded hole is provided on the base 10. The lower end of the screw rod passes through the strip-shaped hole 3011 and is threadedly connected to the threaded hole. The operation knob 3071 is located above the sliding plate 301. By rotating the operation knob 3071, the operation knob 3071 is pressed against the sliding plate 301, and further the sliding plate 301 and the base 10 are relatively locked and fixed. In this way, the operation is convenient and the locking and fixing are reliable.

[0111] Referring Figures 1 to 3 and Figure 5 As shown, in some embodiments of the present invention, the wheel positioning member 30 further includes a second laser 304. The second laser 304 is movably provided on the sliding plate 301 for emitting a laser beam extending along the vehicle transverse direction to position the center of the wheel 60.

[0112] That is to say, the second laser 304 can slide to the outside of the wheel 60 along with the sliding plate 301, and the second laser 304 can emit a laser beam extending along the vehicle width direction. By adjusting the position of the second laser 304, the laser beam emitted by the second laser 304 can be made to coincide with the center of the wheel 60. In this way, the center of the wheel 60 can be positioned by using the laser beam emitted by the second laser 304.

[0113] Referring Figures 1 to 3 and Figure 5 As shown, in an embodiment of the present invention, the wheel positioning member 30 further includes a sliding arm 305, a sliding rod 306, and a second locking member 308. The sliding arm 305 is slidably disposed on the sliding plate 301 along the vehicle longitudinal direction. The sliding rod 306 is slidably disposed on the sliding arm 305 along the vertical direction, and the second laser 304 is mounted on the sliding rod 306. The second locking member 308 is disposed between the sliding arm 305 and the sliding rod 306 for relatively locking and fixing the sliding rod 306 and the sliding arm 305 so that the sliding rod 306 can be selectively fixed at a predetermined height.

[0114] That is to say, the sliding arm 305, the sliding rod 306, and the second locking member 308 are disposed on the sliding plate 301 and can slide along the vehicle width direction together with the sliding plate 301. At the same time, the sliding arm 305 can slide relative to the sliding plate 301 along the vehicle longitudinal direction, and the sliding rod 306 can slide relative to the sliding arm 305 along the vertical direction, and the second laser 304 is mounted on the sliding rod 306. When positioning the center of the wheel 60, the position of the second laser 304 on the sliding rod 306 can be adjusted by sliding the sliding arm 305 along the vehicle longitudinal direction and sliding the sliding rod 306 along the vertical direction, so that the second laser 304 is aligned with the center of the wheel 60, and further ensuring that the laser beam emitted by the second laser 304 can be projected onto the center of the wheel 60.

[0115] In this embodiment, by using the sliding adjustment of the sliding arm 305 and the sliding rod 306 in two different directions of the vehicle longitudinal direction and the vertical direction, the position adjustment of the second laser 304 is realized, and the positioning of the center of the wheel 60 is conveniently and quickly realized.

[0116] Exemplarily, a chute is provided at one end of the sliding arm 305, a slide rail is provided on the sliding plate 301, and the sliding arm 305 is sleeved with the slide rail through a sliding sleeve, thereby realizing the smooth and reliable sliding of the sliding arm 305 relative to the sliding plate 301. In addition, a through hole penetrating vertically is provided at the other end of the sliding arm 305, the sliding rod 306 is slidably inserted into the through hole, and the second laser 304 is fixedly disposed at the upper end of the sliding rod 306. In this way, the vertical position and the vehicle longitudinal position of the sliding rod 306 can be arbitrarily adjusted.

[0117] Optionally, the second locking member 308 is a screw. A screw hole radially penetrating through to the through hole is provided on the sliding arm 305. The screw is threadedly fitted in the screw hole, and by adjusting the depth of the screw in the threaded hole, the sliding rod 306 can be locked and fixed.

[0118] Referring to Figure 5 As shown, in an embodiment of the present invention, the wheel surface positioning member 302 includes a positioning wheel 3021. The positioning wheel 3021 is provided on the sliding plate 301 and the axis of the positioning wheel 3021 extends along the vehicle transverse direction. When using the wheel surface positioning member 302 to position the wheel 60, the outer peripheral surface of the positioning wheel 3021 is tangent to the wheel surface of the wheel 60. Thus, by using the tangency between the positioning wheel 3021 and the wheel surface of the wheel 60, it can be ensured that the positioning of the wheel 60 is more accurate.

[0119] Exemplarily, one side of the sliding plate 301 is fixedly connected to an L-shaped connecting plate 3022. The positioning wheel 3021 is pivotally provided on the L-shaped connecting plate 3022 through a rotating shaft. Thus, on the one hand, it can be ensured that the positioning wheel 3021 is away from the sliding plate 301, facilitating contact with the wheel surface of the wheel 60. On the other hand, the positioning wheel 3021 can rotate, ensuring better contact between the positioning wheel 3021 and the wheel surface of the wheel 60.

[0120] Referring to Figures 1 to 3 As shown, in an embodiment of the present invention, the linkage mechanism 40 includes a pivot arm 401, a first connecting rod 402, a second connecting rod 403, a first push-pull rod 404, and a second push-pull rod 405. Among them, the middle part of the pivot arm 401 is pivotally connected to the base 10. One end of the first connecting rod 402 is pivotally connected to one end of the pivot arm 401, and one end of the second connecting rod 403 is pivotally connected to the other end of the pivot arm 401. One end of the first push-pull rod 404 is pivotally connected to one end of the first connecting rod 402, and the other end of the first push-pull rod 404 is connected to one of the two wheel positioning members 30; one end of the second push-pull rod 405 is pivotally connected to one end of the second connecting rod 403, and the other end of the second push-pull rod 405 is connected to the other of the two wheel positioning members 30.

[0121] That is to say, the pivot arm 401 can rotate about a vertical axis passing through its center. When the pivot arm 401 rotates about the vertical axis, the two ends of the pivot arm 401 rotate in different directions. The two ends of the pivot arm 401 are respectively connected to the first connecting rod 402 and the second connecting rod 403. The first connecting rod 402 is connected to the sliding plate 301 of a wheel positioning member 30 through a first push rod 404, and the second connecting rod 403 is connected to the sliding plate 301 of the other wheel positioning member 30 through a second push rod 405. In this way, the two ends of the pivot arm 401 can drive the first connecting rod 402 and the second connecting rod 403 to move. The first connecting rod 402 then drives the first push rod 404 to move transversely to the vehicle, and the second connecting rod 403 then drives the second push rod 405 to move transversely to the vehicle. Finally, the first push rod 404 and the second push rod 405 respectively drive the sliding plates 301 of the two wheel positioning members 30 to slide towards each other or in opposite directions. Thus, the synchronous movement of the two wheel positioning members 30 towards each other or in opposite directions is achieved.

[0122] In this embodiment, the linkage mechanism 40 with the above structure is adopted. By forming a linkage relationship among the pivot arm 401, the first connecting rod 402, the second connecting rod 403, the first push rod 404 and the second push rod 405, it can ensure that the two wheel positioning members 30 have a higher synchronization degree, thereby improving the calibration accuracy.

[0123] Refer to Figure 3 As shown, in an embodiment of the present invention, the linkage mechanism 40 further includes a first guiding assembly 406 and a second guiding assembly 407. The first guiding assembly 406 is arranged between the first push rod 404 and the base 10 to guide the first push rod 404 to move transversely to the vehicle. The second guiding assembly 407 is arranged between the second push rod 405 and the base 10 to guide the second push rod 405 to move transversely to the vehicle.

[0124] That is to say, the first guiding assembly 406 can be used to realize the guiding of the first push rod 404 in the transverse direction of the vehicle, and the second guiding assembly 407 can be used to realize the guiding of the second push rod 405 in the transverse direction of the vehicle. In this way, it can ensure that the first push rod 404 and the second push rod 405 move smoothly and reliably in the transverse direction of the vehicle.

[0125] Refer to Figures 1 to 2 and Figure 4As shown, in an embodiment of the present invention, the base 10 includes a first side seat 101, a second side seat 102 and a center seat 103. Among them, the second side seat 102 is disposed opposite to the first side seat 101 in the vehicle transverse direction. The center seat 103 is located between the first side seat 101 and the second side seat 102 and is relatively fixed to the first side seat 101 and the second side seat 102. The first laser 20 is provided on the center seat 103. One of the two wheel positioning members 30 is slidably provided on the first side seat 101 in the vehicle transverse direction, and the other of the two wheel positioning members 30 is slidably provided on the second side seat 102 in the vehicle transverse direction.

[0126] That is to say, the first laser 20 is installed on the center seat 103. The first side seat 101 and the second side seat 102 are symmetric with respect to the laser beam 201 emitted by the first laser 20 on the center seat 103. Correspondingly, the two wheel positioning members 30 are respectively slidably installed on the first side seat 101 and the second side seat 102. In this way, it can be ensured that the two wheel positioning members 30 are symmetric with respect to the laser beam 201 emitted by the first laser 20. Its structure is simple and the installation is convenient.

[0127] Exemplarily, the first side seat 101, the second side seat 102 and the center seat 103 are connected by a connecting rod 104, so that the first side seat 101, the second side seat 102 and the center seat 103 are relatively fixed. As Figure 1 shown, there are two connecting rods 104. The first side seat 101 is connected to one end of the two connecting rods 104, the second side seat 102 is connected to the other end of the two connecting rods 104, and the center seat 103 is fixedly installed on the middle parts of the two connecting rods 104 through fixing members.

[0128] The first guiding component 406 may include a first clamping block 4061. The first clamping block 4061 is fixed on the connecting rod 104 through a first fastening member 4062. A first sliding hole is provided on the first clamping block 4061, and the first push rod 404 is slidably sleeved in the first sliding hole. The second guiding component 407 may include a second clamping block 4071. The second clamping block 4071 is fixed on the connecting rod 104 through a second fastening member 4072. A second sliding hole is provided on the second clamping block 4071, and the second push rod 405 is slidably sleeved in the second sliding hole. In this way, the movement guiding of the first push rod 404 and the second push rod 405 can be realized. Its structure is simple and the installation is convenient.

[0129] Refer to Figure 4As shown, in an embodiment of the present invention, the central seat 103 extends along the longitudinal direction of the vehicle. Casters 105 are respectively provided at the bottoms of the first side seat 101, the second side seat 102 and the central seat 103. In this way, the central seat 103, the first side seat 101 and the second side seat 102 form a T-shaped structure, which has a more stable structure. Moreover, the vehicle centering device can be conveniently moved through the casters 105, thus facilitating the movement during the calibration process.

[0130] Referring to Figure 6 As shown, the vehicle calibration device according to an embodiment of the present invention includes an optical alignment calibration bracket 50 and a vehicle centering device as described above. The vehicle centering device is used to center and position the vehicle and project a laser beam 201 onto the optical alignment calibration bracket 50.

[0131] That is to say, after the vehicle centering device positions two opposite wheels 60 on the vehicle transversely, the laser beam 201 emitted by the first laser 20 on the vehicle centering device can coincide with the longitudinal center line of the vehicle. In this way, the calibration of the longitudinal center line of the vehicle is achieved. The optical alignment calibration bracket 50 can be placed at the front bumper of the vehicle. By adjusting the optical alignment calibration bracket 50, the laser beam 201 emitted by the first laser 20 is projected onto a predetermined position on the optical alignment calibration bracket 50, which is convenient for adjusting the optical alignment calibration bracket 50 to be perpendicular to the longitudinal central axis of the vehicle.

[0132] According to the vehicle calibration device provided by the embodiment of the present invention, the linkage mechanism 40 is used to drive the two wheel positioning members 30 to move relatively simultaneously to position two opposite wheels 60 on the vehicle transversely. After the two wheels 60 on the vehicle are positioned transversely, the first laser 20 can be located at the central position between the two opposite wheels 60 on the vehicle transversely, so that the laser beam emitted by the first laser 20 along the longitudinal direction of the vehicle can achieve the calibration of the longitudinal center line of the vehicle. The operation is simple and convenient, the calibration efficiency is improved, and the calibration is accurate and reliable. In addition, the laser beam 201 is projected onto the optical alignment calibration bracket 50, which is convenient for making the optical alignment calibration bracket 50 perpendicular to the longitudinal central axis of the vehicle after the laser beam 201 is projected on the optical alignment calibration bracket 50.
