Automatic driving of automobiles is a future trend, and ADAS (advanced driving assistance system) is a necessary way for automobiles to realize automatic driving. At the beginning of the ADAS technology being applied to luxury vehicles, automobile manufacturers began to gradually penetrate to medium-grade and small-sized vehicles due to the gradual maturity of the technology and the declining trend of the product price. The number of cars with ADAS technology worldwide will be very large in the future, so the after-market of cars will also need to launch ADAS calibration services.

In the related art, the method for calibrating the longitudinal center line of the automobile by the existing calibration equipment comprises the following steps:

(1) and moving the calibration equipment, and aligning the laser emitted from the center of the visual inspection calibration equipment to the center of the front bumper of the automobile. In the method, laser emitted from the center of the calibration equipment is aligned to the center of a front bumper of an automobile through preliminary visual inspection, the longitudinal center plane of the calibration equipment and the longitudinal center plane of the automobile is not in a vertical state, so that laser points reflected by a reflector are deviated to the inner side or the outer side of a laser scale, the laser points reflected by the laser scale on the two sides of the automobile are difficult to find, and the angle deviation in the left-right direction exists.

(2) And measuring the distance between the calibration equipment and the center of a front bumper or a front wheel of the vehicle by using a measuring tape or a laser range finder. According to the method, the conditions of uneven ground and unadjusted suspension system of a vehicle chassis are ignored, and the axle of a rear wheel of the vehicle and the cross beam of the calibration equipment are not on the same horizontal plane, so that the laser points at two sides are different in emission direction, and the angular deviation in the vertical direction exists.

(3) And respectively installing the two hub clamps on the rear wheels at the two sides of the vehicle, respectively installing a laser into the two hub clamps, and then opening the laser to calibrate. Due to the angular deviation in both directions, the returning laser points on both sides of the vehicle cannot effectively hit the laser scale. In order to enable laser points to be reflected by the reflector, scales on the laser graduated scales on the two sides are equal, an operator needs to adjust the calibration equipment and the laser for multiple times between the calibration equipment and the rear wheels on the two sides of the automobile, and therefore the operation process is complex, the learning cost is high, and the efficiency is reduced.

(4) And rotating the laser, and adjusting the irradiation direction of the laser point to irradiate the laser point on the graduated scales on two sides of the cross beam of the calibration equipment. And adjusting the calibration equipment until the scales of the laser points on the graduated scales on the two sides of the beam are equal. In the method, a certain distance is reserved between the calibration equipment and the rear wheel of the vehicle, so that whether scales on the laser point alignment lasers on the two sides are equal or not is inconvenient to observe, the calibration difficulty is increased, and the time cost is increased.

The following describes a vehicle calibration apparatus of an embodiment of the present invention in detail with reference to the accompanying drawings.

Referring to fig. 1 to 15, a vehicle calibration apparatus for calibrating a longitudinal centerline of a vehicle according to an embodiment of the present invention includes a pair of alignment brackets 100, a wheel centering fixture 200, and a first laser 300.

Specifically, the light calibration bracket 100 has a light sensing calibration member 11. The wheel centering jig 200 has two wheel alignment members 21 for aligning two opposite wheels 400 in the lateral direction of the vehicle, that is, the two wheel alignment members 21 can align two front wheels or two rear wheels of the vehicle, respectively.

The first laser 300 is disposed between the two wheel alignment members 21, and is used for emitting the first laser beam 30 extending along the longitudinal direction of the vehicle and projecting the first laser beam to the light receiving target 11. When two of the wheel alignment members 21 are aligned with two of the opposing wheels 400, the first laser 300 is located at a midpoint of a line connecting the two opposing wheels 400.

During calibration, two opposite wheels 400 in the transverse direction of the vehicle are positioned by using two wheel positioning parts 21 in the wheel centering fixture 200, after the two wheel positioning parts 21 position the two opposite wheels 400, the first laser 300 is located at the midpoint of the connecting line between the two wheels 400, and then the first laser 300 is turned on, so that the first laser beam 30 emitted by the first laser 300 extends in the longitudinal direction and is emitted to the light receiving calibration piece 11 of the light aligning calibration support 100, and at this time, the first laser beam 30 emitted by the first laser 300 can be located on the longitudinal center line of the vehicle. In addition, the alignment calibration bracket 100 is adjusted to enable the alignment calibration bracket 100 to be perpendicular to the laser beam, so that the alignment calibration bracket can be adjusted to be perpendicular to the longitudinal center line of the vehicle, and then the radar and/or the camera can be calibrated by using a mounting tool on the alignment calibration bracket 100.

According to the vehicle calibration device provided by the embodiment of the invention, two wheels 400 in the transverse direction of the vehicle can be positioned by moving two wheel positioning assemblies in the transverse direction of the vehicle in opposite directions, because the first laser 300 is positioned between the two wheel positioning members 21, and when the two wheel positioning members 21 position two opposite wheels 400, the first laser 300 is positioned at the midpoint of a connecting line between the two opposite wheels 400, as long as the two wheel positioning members are positioned with the two wheels 400, the first laser beam 30 emitted by the first laser 300 can be overlapped with the longitudinal centerline of the vehicle, so that the calibration of the longitudinal centerline of the vehicle is realized, the operation is simple and convenient, the calibration efficiency is high, and the calibration is accurate and reliable by using the centering calibration mode of the first laser 300. In addition, the first laser beam is projected to the light receiving calibration piece 11 of the alignment calibration bracket 100, so that the alignment calibration bracket 100 can be perpendicular to the longitudinal central axis of the vehicle by adjusting the alignment calibration bracket 100.

Referring to fig. 3 to 7, in some embodiments of the present invention, the wheel centering fixture 200 includes a base 20 and a linkage 22, the first laser 300 is disposed on the base 20, and the two wheel alignment members 21 are disposed on the base 20 opposite to each other in the vehicle transverse direction and symmetrical with respect to the first laser beam 30. A linkage 22 is connected between the two wheel alignment members 21 to move the two wheel alignment members in the vehicle lateral direction synchronously toward each other or in opposite directions relative to the base 20.

That is, both the wheel positioners 21 can move relative to the base 20, and the two wheel positioners 21 move in directions approaching or departing from each other in the lateral direction of the vehicle, and the linkage mechanism 22 is connected between the two wheel positioners 21, so that when one wheel positioner 21 moves a predetermined distance, the other wheel positioner 21 can move the same distance by the linkage action of the linkage mechanism 22, and thus the two wheel positioners 21 can move synchronously.

Since the two wheel alignment members 21 are symmetrical with respect to the first laser beam 30 emitted from the first laser 300, the first laser beam 30 of the first laser 300 is located at a midpoint of a connecting line between the two wheel alignment members 21, and when the two wheel alignment members 21 move relative to the base 20, the first laser 300 remains stationary and the position of the first laser beam 30 emitted from the first laser 300 remains unchanged, so that when the two wheel alignment members 21 are aligned on the two opposite wheels 400, the midpoint of the connecting line between the two wheel alignment members 21 is coincident with the midpoint of the connecting line between the two opposite wheels 400, and the first laser beam 30 emitted from the first laser 300 can be maintained on the vehicle longitudinal center line.

When the wheels 400 are positioned, the wheel centering fixture 200 is placed at the bottom of the vehicle, and the distance between the two wheel positioning parts 21 can be adjusted by the two wheel positioning parts 21 moving in the transverse direction of the vehicle, so that the distance between the two wheel positioning parts 21 is just suitable for positioning the two wheels 400, for example, the two wheel positioning parts 21 stop at the outer sides of the two wheels 400, and thus, the positioning of the two wheels 400 can be completed. Because the two wheel alignment members 21 can move synchronously, when the wheel 400 is aligned, only one wheel alignment member 21 is adjusted to a proper position to align the wheel 400, the other wheel alignment member 21 can be automatically and synchronously adjusted to a proper position to align the other wheel 400, so that the alignment operation is very convenient and fast, and the two wheel alignment members 21 move synchronously, so that the first laser 300 is always positioned at the midpoint of the connecting line between the two wheel alignment members 21.

Referring to fig. 8-15, in some embodiments of the present invention, the collimating optic support 100 includes a collimating optic 10, the collimating optic 10 having a pair of light holes H10 for the first laser beam 30 to pass through. The light receiving index piece 11 is pivotable about a vertical axis relative to the light pair 10, and the light receiving index piece 11 has a scale 111, and the scale 111 is opposite to the light pair H10 and extends in the transverse direction of the vehicle, so that the first laser beam 30 emitted from the light pair H10 can be projected onto the scale 111.

The horizontal slide rail 18 is disposed on the light receiving calibration piece 11 and is parallel to the scale 111. Preferably, the horizontal slide rail 18 is slidably disposed on the light receiving calibration member 11 along the transverse direction of the vehicle, and is parallel to the scale 111. This horizontal slide rail 18 can be used for installing radar calibration board and pattern board, and the radar calibration board is used for calibrating the radar of vehicle, and the pattern board is used for calibrating the camera of vehicle, so, can utilize this to the calibration support 100 of light, can assist the calibration of the radar and the camera of carrying out the vehicle. That is, the aligning optical aperture H10 of the aligning optical element 10 is opposite to the scale 111 of the light receiving target 11 in the longitudinal direction of the vehicle, and the first laser beam 30 emitted from the first laser 300 can be projected onto the scale of the light receiving target 11 after passing through the aligning optical aperture H10. Meanwhile, the light receiving calibration piece 11 can rotate around the vertical axis, so that the graduated scale deflects relative to the light hole H10, namely, the angle of the graduated scale is adjusted, and then a specific scale value projected onto the graduated scale by the first laser beam 30 is adjusted, so that whether the light receiving calibration support 100 is perpendicular to the longitudinal center line of the vehicle can be determined by taking the scale value projected onto the graduated scale 111 by the first laser beam 30 as a reference.

For example, a plurality of scale values may be set on the scale 111, one of the scale values is set as a calibration scale 1111, and the other scale values are set as offset reference scales 1112, when the first laser beam 30 is projected to the calibration scale 1111, the scale 111 is perpendicular to the first laser beam 30, and when the first laser beam 30 is projected to the offset reference scales 1112, the scale 111 is not perpendicular to the laser beam, for example, the scale value of the calibration scale 1111 is set to be 0 at the center of the scale 111, and the offset reference scales 1112 at both sides of the calibration scale 1111 are sequentially set with the plurality of scale values. Therefore, in the adjusting process, the light receiving calibration piece 11 rotates around the vertical axis, the angle of the graduated scale is adjusted, the first laser beam 30 is just projected to the position of the calibration scale 1111, the graduated scale 111 and the first laser beam 30 form a vertical state, at the moment, the horizontal slide rail 18 is parallel to the graduated scale 111, and therefore when the first laser beam is projected to the calibration scale 1111 of the graduated scale 111, the first laser beam is perpendicular to the graduated scale 111, and meanwhile, the first laser beam is also perpendicular to the horizontal slide rail 18, so that the horizontal slide rail 18 can be determined to be perpendicular to the longitudinal center line of the vehicle.
