Observing the relative position between the longitudinal central line of the front part of the vehicle body and the longitudinal light of the laser (namely, the relative position equivalent to observing the relative position between the longitudinal central line of the front part of the vehicle body and the middle position of the traction track), switching on the automatic vehicle straightening device positioned at the bottom of the front shaft of the vehicle 6, adjusting the motion direction of the bearing support 3, driving the front shaft of the vehicle 6 to move along the longitudinal light direction of the laser on the Y axis of the whole vehicle (the width direction of the vehicle 6), and when the longitudinal central line of the front part of the vehicle body is coincident with the longitudinal light of the laser, closing the servo stepping motor 213 to stop the work of the transmission mechanism 2.
9. Observing the relative position of the longitudinal central line of the tail part of the vehicle body and the longitudinal light of the laser (namely, being equivalent to observing the relative position of the longitudinal central line of the tail part of the vehicle body and the middle position of the traction track), switching on the automatic vehicle centering device positioned at the bottom of the tail shaft of the vehicle 6, adjusting the motion direction of the bearing support 3, driving the tail shaft of the vehicle 6 to move along the longitudinal light direction of the laser on the Y axis of the whole vehicle (the width direction of the vehicle 6), and closing the servo stepping motor 213 when the longitudinal central line of the tail part of the vehicle body and the longitudinal light of the laser coincide to stop the transmission mechanism 2.
10. At this time, the centering of the vehicle 6 has been completed, the hydraulic system of the vehicle automatic centering device is adjusted to retract the support portion 5, the height of the vehicle automatic centering device is lowered, the test vehicle is dropped to the ground, the vehicle automatic centering device is removed, and the departure is prepared.
