Will be described with reference to the flowchart of FIG.

The portal frame 4 is stopped at the start position, and the front wheel of the vehicle is positioned between the tire stoppers 107 and stopped with the top brush 8 at the upper limit position.

When the start switch 101 is pressed, the memories M1 to M4 are cleared, and the top brush 8 is rotated forward at high speed and lowered. When the top brush 8 reaches the lower limit position, the forward running of the portal frame 4 is started (step S1).

Next, the traveling position L detected by the traveling position detecting means C1 is read, and the current vehicle height H detected by the vehicle height detecting means C3 is read (steps S2 and S3).
3, S4), and set the vehicle height H at a distance L ahead of the current traveling position L by X (the distance between the top brush 8 and the vehicle height detecting means C3).
X (LX = L + X) is stored (step S5). Only when the first vehicle height H is stored, the vehicle height H is stored from the current traveling position L to the traveling position LX.

The control device 54 sets the top brush target position when the gate-shaped frame 4 is at the predetermined traveling position L from the detection signals of the traveling position detecting means C1 and the vehicle height detecting means C3, and detects the target position by the elevating position detecting means C2. Based on the difference between the set position and the target position, the top brush lifting / lowering motor 24 is controlled to set the top brush 8 at a substantially constant distance from the upper surface of the vehicle body.

Next, the vehicle height HA at the traveling position LA (LA = L + R1) ahead of the current position L by R1 and the vehicle height HA1 at the traveling position LA1 (LA1 = LA + Y1) ahead of the traveling position LA by Y1 are read out ( Steps S6, S7, S
8) When the difference between the vehicle height HA and the vehicle height HA1 is determined to be equal to or higher than the predetermined upward gradient, that is, when the windshield surface is determined, the current position L1 is stored in the memory M1 (steps S9 and S10). When the current position L1 is stored in this manner, the top brush 8 is rotated at a low speed to prevent the wiper W1 from being damaged when the top brush 8 cleans the windshield surface (steps S2, S3, S11, S2).

Next, the vehicle height HB at a travel position LB (LB = L + R2) ahead of the current position L by R2 and the vehicle height HB1 at a travel position LB1 (LB1 = LB + Y2) ahead of the travel position LB by Y2 are read out ( Steps S4, S5, S6

Is smaller than a predetermined difference, that is, when the rear glass surface is determined, the current position L3 is stored in the memory M3 (steps S22 and S23). Thereby, the top brush 8 is rotated at a low speed, and the wipers W2 and W3 are prevented from being damaged when the top brush 8 cleans the rear glass (Steps S2, S3, S11, S17, S24,
S25, S26, S27). W2 is a horizontal wiper at the stop position, and W3 is a vertical wiper at the stop position.

Next, a vehicle height HD at a travel position LD (LD = LR4) behind the current position L by R4 and a vehicle height HD1 at a travel position LD1 (LD1 = LD-Y4) Y4 behind the travel position LD. (Steps S4, S5, S6,
S20, S28), when it is determined that the vehicle height HD and the vehicle height HD1 have changed from a predetermined slope down to below, that is, when the trunk surface is determined, the current position L4 is stored in the memory M4.
Is stored (steps S29 and S30). This allows
The top brush 8 is rotated at high speed to effectively clean the trunk surface (Steps S2, S3, S11, S17, S2).

Next, when the gate-shaped frame 4 travels a predetermined distance from the traveling position L where the vehicle height detecting means C3 has detected the rear end of the automobile, the backward traveling is started with the top brush 8 rotating at a high speed in the normal direction.

When the current position L is between L4 and L3 and between L2 and L1 due to the reverse running, the top brush 8 is rotated at a low speed to prevent the wiper from being damaged, and to be moved to another position. If there is, the top brush 8 is rotated at a high speed to secure a cleaning effect (steps S2, S3, S1).
1, S17, S24, S31, S32, S33, S3

Note that R1 to R4, Y1, Y2, Y4, and X are predetermined values set in advance.

Thus, the windshield surface and the rear glass surface are determined based on the magnitude of the gradient of the vehicle body surface, and the top brush 8 is rotated at a low speed when cleaning the front glass surface and the rear glass surface. The wiper can be prevented from being damaged.
