Finally, the side brushes 4 and 4 are returned to the vertical posture, and brushing is performed to the rear end of the vehicle body in the vertical posture. (Fig. 8h)

FIG. 9 shows the operation of brushing around the door mirror of the wagon car with the side brush when the car wash machine main body 1 goes forward.
Since the vehicle height is higher than that of a normal vehicle and the mounting height of the door mirror is high, the control described for a normal vehicle is used to prevent the side brushes 4 and 4 from contacting the door mirror when the side brushes 4 and 4 are inclined by a predetermined amount θ3. The point Ld2 (intermediate point between the control point Ld1 and the control point Ld3) is not set, and the side brushes 4 and 4 are controlled using the door mirror start point DM-s and the door mirror end point DM-e.

  First, until the side brushes 4 and 4 reach the control point Ld1 ', the side brushes 4 and 4 are set to a vertical posture in the front-rear direction, and the upper side in the left-right direction is set to a C-shape posture approaching the car A. Then, the side of the vehicle body is brushed (FIG. 9a). When the side brushes 4 and 4 reach the control point Ld1 ', the travel of the car wash machine body 1 is temporarily stopped, and the side brushes 4 and 4 are inclined to the front of the car wash machine body 1 by a predetermined amount θ3 (reverse tilting attitude). ) And brush the vehicle body at the front lower part of the door mirror (FIG. 9b).

  Next, the side brushes 4 and 4 are brought into a posture (forward leaning posture) in which the lower side is inclined by a predetermined amount θ3 behind the car wash machine body 1 (forward leaning posture) from the forward leaning posture (FIG. 9c), and the door mirror starting point DM-s from the control point Ld1 ′ as it is. The main body 1 is made to travel until the vehicle body in front of the door mirror is brushed by the side brushes 4 and 4 (FIG. 9d).

  When the side brushes 4 and 4 reach the door mirror starting point DM-s, the traveling of the car wash machine body 1 is temporarily stopped, and the side brushes 4 and 4 are opened to a position where they do not come into contact with the door mirror to avoid the door mirror. The side brushes 4 and 4 that are open at the avoidance position are now in a posture in which the lower side is tilted by a predetermined amount θ3 in front of the car wash machine body 1 (rear tilting posture), closed in this rearward tilting posture, and brought into contact with the vehicle body. Brush the upper body (FIG. 9e).

  After that, the car wash machine body 1 is caused to travel with the side brushes 4 and 4 tilted backward (FIG. 9f). When the side brushes 4 and 4 reach the control point Ld3 ′, the car wash machine body 1 is temporarily stopped running, This time, the side brushes 4 and 4 are brought into a posture in which the lower side is inclined by a predetermined amount θ3 toward the rear of the car wash machine body 1 (forward leaning posture), and the vehicle body under the door mirror is brushed (FIG. 9g). Finally, the side brushes 4 and 4 are returned to the vertical posture, and brushing is performed to the rear end of the vehicle body in the vertical posture. (Fig. 9h)

  As described above, since the side brush is inclined in the front-rear direction with respect to the periphery of the door mirror and brushed, when a normal vehicle is washed, a washing range as shown in FIG. When the wagon car is washed, a washing range as shown in FIG. 10B is obtained, and brushing can be performed as much as possible on the upper and lower body parts of the door mirror, which was previously left unwashed. In the case where the brushing process is carried out with the car wash machine main body 1 being carried back, the procedure is reversed from that in the forward movement, that is, in the order of (h) to (a) shown in FIG.

  Although the present invention is configured as described above, various methods are conceivable as means for detecting the door mirror. For example, when the present invention employs any means of a reflective photoelectric switch, CCD camera, or PSD distance sensor for detecting the contour of the side of an automobile proposed in Japanese Patent Application No. 8-128429, the door mirror can be further improved. It becomes possible to detect reliably.

  In particular, the side brush can be moved along the shape of the vehicle body to provide a car wash machine with little unwashed residue.
