- step S1 when the return is started from the halfway stop (step S1: hereinafter, "step” is appropriately abbreviated as “S1"), first, the wiper switch detection unit 45 starts restarting. Whether or not there is a request (ReStart Rq) is determined (S2).
- the motor stop instruction is given to the drive circuit 35 to exit the routine.
- step S4 the wiper switch detection unit 45 confirms the operation control state of the wiper device 1 (the state of the wiper switch 24 in S4).
- step S4 if the control state of the wiper switch 24 is $ 0 (storage instruction), the process proceeds to step S5, otherwise the process proceeds to step S21. If the operation control state is $ 0 in step S4, the process proceeds to step S5, the arm operation determination unit 47 determines that the wiper operation is started from the return path operation, and an instruction to that effect is given to the motor operation instruction unit 48. , The wiper arms 5 and 6 operate in the return operation (P part in FIG. 4).

It is located below position M. Even if the wiper arms 5 and 6 fall at this position, they do not interfere with the engine hood 8, and if the wiper arms 5 and 6 do not move from the arm fall position X, the arm falls so that the entire blade hits the windshield 7 and the tip of the blade falls. The hard part of the cap does not hit the glass. That is, the arm collapse position X is a position where the windshield 7 is not adversely affected even if the wiper arms 5 and 6 in the locked back state are collapsed there.
- step S6 When it is confirmed in step S6 that the wiper arms 5 and 6 have reached the arm collapse position X (point A in FIG. 4), the process proceeds to step S8, and the arm operation determination unit 47 receives a signal from the wiper switch detection unit 45. Check the operation control status of the wiper device 1 again based on (whether the control status is $ 0 or not). At that time, if the control state is $ 0, the driver determines that he / she intends to store the wiper from the service position SP, and proceeds to step S9 to temporarily stop the wiper arms 5 and 6 at the arm collapse position X ( Q part of FIG. 4).
- step S9 the stop time is clocked by the timer 43, and the wiper arms 5 and 6 stop at a predetermined time (about 1 to 2 seconds, here set to 1.5 seconds). Then, the stopped state is maintained while checking the operation control state until the stop time elapses (S9 ⁇ S8 ⁇ S9: Q part in FIG. 4).
- the wiper arms 5 and 6 move from the service position SP (upward reversal position U side) to the arm fall position X in the locked back state, they fall to the windshield 7 side there. Therefore, in the control according to the present invention, when the wiper arms 5 and 6 come to the arm fall position X, they are temporarily stopped there to give a margin time for the wiper arms 5 and 6 to fall safely (insurance operation). As a result, even if the retracting operation is performed in the locked back state, the wiper arms 5 and 6 fall at the arm fall position X without interfering with the engine hood 8, and the wiper blade 18 is quietly and surely on the windshield 7. Go back and move to the storage position.
- the wiper arms 5 and 6 interfere with the engine hood 8 and fall into the windshield so that the wiper blades are twisted as the arm moves. It is possible to prevent the windshield 7 from being damaged by the cap at the tip of the wiper blade.
- step S9 the wiper arms 5 and 6 are temporarily stopped at the arm collapse position X, and once the stop time has elapsed while the control state is $ 0, the process proceeds to step S10.
- the wiper arms 5 and 6 have returned to the normal state on the windshield 7 even in the initially locked back state, and in step S10, the wiper arms 5 and 6 operate again in this state.
- Point B in FIG. 4 move to the storage position (R part in FIG. 4).
- the wiper arms 5 and 6 are temporarily stopped at the arm collapse position X. When stopped, it safely returns to the windshield 7 and returns to the stowed position in the normal state.
- step S8 when the operation control state of the wiper device 1 is other than $ 0, the driver initially intended to store the wiper from the service position SP, but after that, it is determined that another operation has been selected. Then, the process proceeds to step S11.
- step S11 the current operation control state ($ 2 to $ 4) is determined. If the operation control state is $ 2 to $ 4 in step S11, the process proceeds to step S12 to start the outbound operation. That is, the wiper arms 5 and 6 (H portion in FIG. 5) that are moving from the service position SP to the arm tilting position X by the return operation (S5) are reversed in the operating direction at the arm tilting position X (FIG. 5).
- the outbound route is operated to move in the upward reversal position U direction (part I in FIG. 5).
- the next operation is not the retracting operation, and interference with the engine hood 8 does not occur immediately after that. Therefore, prioritize the wiping operation and the movement to the service position SP, and temporarily stop at the arm collapse position X. Instead, immediately reverse it in the outward direction.
- the flipping at the arm tilting position X itself is an insurance operation, and the wiper arms 5 and 6 return to the windshield 7 at the arm tilting position X and head toward the upward flipping position U.
- the wiper arms 5 and 6 reach the upper inversion position U (here, the same position as the service position SP) in the normal wiping state, and when the operation control state is $ 2, $ 3, then the normal wiping operation is performed. It returns (part J in FIG. 5), and when the operation control state is $ 4, it stops at the service position SP.
- the operation control state is not $ 2 to $ 4 in step S11, for example, the wiper arms 5 and 6 are stopped at the arm collapse position X ($ 1), and the wiper arms 5 and 6 are stopped on the spot (for example).
- an operation control state such as $ 5
- the process proceeds to step S13, and the wiper arms 5 and 6 are stopped at the arm collapse position X.
- step S2 if the operation control state is other than $ 0 in S2, the process proceeds to step S21, and it is first confirmed whether or not the operation control state is $ 1.
- the operation control state is $ 1
- the process proceeds to step S22 to start from the return path operation, and then proceeds to step S6.
- step S8 if $ 1 is maintained, the process proceeds from step S8 to S11 ⁇ S13, and the wiper arms 5 and 6 stop at the arm collapse position X (FIG. 6A). If the operation control state has changed from $ 1 to $ 0, the process proceeds to step S9, temporarily stops as described above, and then moves to the storage position (S10).
- step S21 If the operation control state is other than $ 1 in step S21, the process proceeds to step S23, and it is confirmed whether or not the operation control state is $ 4. If the operation control state is $ 4, the process proceeds to step S24, and if the wiper arms 5 and 6 are in the service position SP, the wiper arms 5 and 6 are maintained as they are. To the service position SP. On the other hand, if the operation control state is other than $ 4, the process proceeds to step S25, and it is confirmed whether or not the operation control state is $ 2 (LO operation) or $ 3 (HI operation).
- the operation control state is not $ 2 or $ 3
- step S26 it is determined whether the positions of the wiper arms 5 and 6 are above or below the windshield center M.
- step S26 when the wiper arms 5 and 6 are above the windshield center M, the arm collapse position X is below the windshield center M, so the process proceeds to step S27 and the return operation is started. Proceeding to step S6, the wiper arms 5 and 6 are moved to the arm collapse position X (FIG. 6B), and the processing after S6 is performed.
- step S28 the process proceeds to step S28 and starts from the outward operation (FIG. 6 (c)).
- the operations of S26 to S28 are mainly control processes when the wiper arms 5 and 6 are stopped at the wiping intermediate position, and when the wiper arms 5 and 6 are in the service position SP, the operation of S28 is omitted and the operation is changed to S6. move on.
- the first downward reversal position is the arm collapse position X from the flow of S6 ⁇ S8 ⁇ S11 ⁇ S12 from S27 and S28. That is, in the control according to the present invention, even if the wiper arms 5 and 6 start wiping from the service position SP (or a halfway stop state at another position) in the locked back state, the first downward reversal position is the arm. It becomes the fall position X. Therefore, the wiper arms 5 and 6 safely return to the windshield 7 at the arm tilting position X, then move to the upward reversing position U, and return to the normal wiping operation. Therefore, when restarting from the lockback state, it is possible to prevent a situation in which the wiper blade falls down on the windshield so as to be twisted and the windshield 7 is damaged.
- the wiper arm 5 such as the service position SP
- the wiper arm 5 remains in the lockback state from a position in the middle of the wiping operation such as the inverted position U side above the arm tilting position X.
- the wiper operation is temporarily stopped at the arm tilting position X, so that the wiper arms 5 and 6 and the wiper blade 18 are completely tilted and then the wiper blade and the like are stored. Avoid the collision of 7 and prevent damage to the windshield 7.
- the first downward reversal position is set to the arm tilt position X, so that the wiper arms 5 and 6 and the wiper blade 18 are safely tilted while the wiper arms 5 and 6 are directed to the upward reversal position U.
- the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof. That is, in the above-described embodiment, when the wiper arm is locked back when the wiper blade is replaced, the wiper arm in the locked back state interferes with the engine hood and collapses in the subsequent wiper operation. Is generally applicable when the wiper device is operated with the wiper arm locked back. For example, when the wiper arm is locked back as a measure against snowfall, it can be applied even when the wiper device is operated in the same state.
- the service position SP is set at the same position as the upper inversion position U is shown, but both may be set at different positions.
- the service position SP is set to the center position M. It is also possible to set the position between the upper inversion position U and the upper inversion position U.
- the center position M the center of the upside down positions U and L (the center of the wiping area) may be adopted instead of the center of the windshield 7.
- the temporary stop time at the arm tilting position X is not limited to 1 to 2 seconds, and can be set as appropriate, and may be less than 1 second or more than 2 seconds. However, if it is too short, its significance as an insurance operation for safely tilting the arm blade is diminished, and if it is too long, it gives the driver a sense of redundancy, so about 1.5 seconds is preferable.

Abstract
Description
[S8にて動作制御状態が$0以外の場合]
ステップS4の時点では制御状態$0(アーム倒れ位置Xで一旦停止させて格納)が選択されていたが、その後、他の制御状態($2~$4)が選択された場合である。この場合、ワイパスイッチの制御状態としては次の6通りのものが設定されている。
$0:ワイパアーム5,6をアーム倒れ位置Xで一旦停止させて格納する。
$1:ワイパアーム5,6をアーム倒れ位置Xで停止させる。
$2:ワイパアーム5,6をLO作動させる。
$3:ワイパアーム5,6をHI作動させる。
$4:ワイパアーム5,6をサービスポジションSPに移動させる。
$5:ワイパアーム5,6をその場で停止させる。
次に、ステップS2にて、動作制御状態が$0以外の場合は、ステップS21に進み、動作制御状態が$1であるかどうかがまず確認される。動作制御状態が$1の場合は、ワイパアーム5,6をアーム倒れ位置Xまで移動させるべく、ステップS22に進んで復路作動から開始させ、ステップS6に進む。その後、$1が維持されている場合は、ステップS8からS11→S13に進み、ワイパアーム5,6はアーム倒れ位置Xで停止する(図6(a))。なお、動作制御状態が$1から$0に移行していた場合は、ステップS9に進み、前述のように一旦停止した後、格納位置に移動する(S10)。
すなわち、前述の実施形態では、ワイパブレード交換の際にワイパアームをロックバック状態にした場合に、その後のワイパ動作においてロックバック状態のワイパアームがエンジンフードに干渉して倒れる現象を述べたが、本発明は、ワイパアームをロックバック状態にしたままワイパ装置を作動させた場合全般に適用可能である。例えば、降雪対策のためにワイパアームをロックバック状態としたとき、そのままの状態でワイパ装置を作動させた場合にも適用可能である。
