- FIGS. 5 and 6 are started by turning on the ignition switch 15 (step S1).
- the execution and determination in all steps shown in FIGS. 5 and 6 are processed in the controller 23a (see FIG. 2).
- step S2 it is determined whether or not the wiper switch 14 is on. If it is determined in step S2 that the wiper switch 14 is on (Yes), the process proceeds to step S3, where a driving current is supplied to the DR-side wiper motor 20 to perform a reciprocating wiping operation. On the other hand, if it is determined (No) in step S2 that the wiper switch 14 is off (OFF), the process proceeds to step S4, and the stop state of the DR-side wiper motor 20 is maintained.
- step S5 it is determined whether or not the wiper switch 14 is turned off. If it is determined in step S5 that the wiper switch 14 is off (Yes), the process proceeds to step S6. On the other hand, if it is determined (No) in step S5 that the wiper switch 14 is on (ON), the process returns to step S3, and the DR-side wiper motor 20 is continuously operated for reciprocal wiping.
- the controller 23a performs the DR-side wiper between the lower inversion position LRP and the upper inversion position URP based on the electrical signal from the MR sensor 23b (see FIG. 2). The blade 21b is reciprocated.
- step S6 based on the determination result that the wiper switch 14 is turned off, it is determined whether or not the previous stop position of the DR wiper blade 21b is the lower stop position APS1.
- the past stop position information of the DR wiper blade 21b is obtained from information stored in the RAM or the like of the controller 23a. If it is determined in step S6 that the previous stop position of the DR-side wiper blade 21b was the upper-side stop position APS2 (No), the process proceeds to step S7, and the storage operation (A) shown in FIG. 4 is executed. .
- step S7 and step S8 means that the DR-side wiper blade 21b is moved to the lower side of the windshield 11 beyond the lower inversion position LRP, and is directed to the lower-side stop position APS1. It is an action to dodge.
- step S8 it is determined whether or not the DR side wiper blade 21b has reached the lower side stop position APS1. If it is determined in step S8 that the lower stop position APS1 has been reached (Yes), the process proceeds to step S4, the supply of drive current to the DR wiper motor 20 is stopped, and the DR wiper motor 20 is stopped. As a result, the DR-side wiper blade 21b stops at the position of the black circle (1) in FIG. 4, and enters the “stop state A” shown in FIG. The direction of facing can be changed to face in a different direction. On the other hand, if it is determined in step S8 that the lower stop position APS1 has not yet been reached (No), the process returns to step S7 to continue the storage operation (A).
- step S6 If it is determined in step S6 that the previous stop position of the DR-side wiper blade 21b is the lower stop position APS1 (Yes), the process proceeds to step S9 to execute the storing operation (B) shown in FIG. .
- the storing operation (B) performed in step S9 to step S12 means that the DR-side wiper blade 21b is moved to the lower side of the windshield 11 beyond the lower inversion position LRP to reach the lower limit position EPSL during the stop operation. This is an operation in which the DR-side wiper motor 20 is reversely rotated and moved toward the upper stop position APS2 after being moved once.
- step S10 it is determined whether or not the DR-side wiper blade 21b has reached the lower limit position EPSL during the stop operation. If it is determined in step S10 that the stop operation lower limit position EPSL has been reached (Yes), the process proceeds to step S11, and the DR-side wiper motor 20 is rotated in the reverse direction. Thereby, the DR side wiper blade 21b is driven to the upper side stop position APS2 side and moved to the upper side of the windshield 11 (see FIG. 4). On the other hand, if it is determined in step S10 that the stop operation lower limit position EPSL has not yet been reached (No), the process returns to step S9 to continue the storage operation (B).
- step S12 it is determined whether or not the DR-side wiper blade 21b has reached the upper stop position APS2. If it is determined in step S12 that the upper stop position APS2 has been reached (Yes), the process proceeds to step S4, the supply of drive current to the DR wiper motor 20 is stopped, and the DR wiper motor 20 is stopped. As a result, the DR-side wiper blade 21b stops at the position of the black circle (2) in FIG. 4, and enters the “stop state B” shown in FIG. The direction of facing can be changed to face in a different direction. On the other hand, if it is determined in step S12 that the upper stop position APS2 has not yet been reached (No), the process returns to step S11 to continue the storage operation (B).
- steps S13 to S24 regardless of the on / off operation of the wiper switch 14, the direction in which the tip side of the lip 71 faces is different between “stop state A” and “stop state B” in FIG. A process of reliably changing, that is, a lip folding operation is executed.
- step S13 it is determined whether or not the number of times the vehicle speed signal is input from the vehicle speed sensor 16, that is, the number of times the vehicle speed is detected is a predetermined n times or more. If it is determined in step S13 that the number of vehicle speed detections is less than the predetermined n times (No), a return process is returned to step S2 in FIG. On the other hand, if it is determined in step S13 that the number of vehicle speed detections is greater than or equal to the predetermined n (Yes), the process proceeds to step S14, and the lip folding operation is executed in the subsequent steps. That is, the controller 23a performs a lip folding operation every time the number of vehicle speed detections is n times or more.
- the number n of vehicle speed detections is set to 5 times, for example. Accordingly, it is not necessary to frequently change the direction in which the tip side of the lip 71 faces each time the ignition switch is turned on or off as before, and thus the early deterioration of the lip 71 is prevented.
- step S14 it is determined whether or not the DR wiper blade 21b is currently stopped at the lower stop position APS1. If it is determined in step S14 that the position is the lower stop position APS1 (Yes), the process proceeds to step S15, the drive current is supplied to the DR wiper motor 20, and the DR wiper blade 21b is moved to the lower limit position EPSL side during the stop operation. To drive.
- step S16 it is determined whether or not the DR-side wiper blade 21b has reached the lower limit position EPSL during the stop operation. If it is determined in step S16 that the stop operation lower limit position EPSL has been reached (Yes), the process proceeds to step S17, and the DR-side wiper motor 20 is rotated in the reverse direction. Thereby, the DR side wiper blade 21b is driven to the upper side stop position APS2 side and moved to the upper side of the windshield 11 (see FIG. 4).
