- the wiper operation is in a different form from the normal operation, the driver can be informed of the device failure by this process.
- the operation of the wiper device in such a control mode is a very controllable mode, and it is not preferable to continue the operation for an excessively long time. For this reason, in the control processing of FIG. 5, if the processing of steps S4 and S5 is performed for a predetermined time (for example, 10 minutes), the motor 2 is stopped to maintain the device. That is, in step S6, the continuation time of the processing in steps S4 and S5 is confirmed, and if it exceeds a predetermined time, the flow proceeds to step S7 to stop the motor 2.

- Execute While executing such normal control, the presence or absence of a motor pulse input is monitored in step S12 as in the case of the first embodiment, and if there is a motor pulse input, normal control is continued. S11) If there is no input, the process proceeds to step S13 and below to execute the abnormality processing.
- step S13 first, it is confirmed whether or not the lockable state of the motor 2 is detectable. If there is no motor pulse input, the current position of the arm cannot be recognized on the control device side, and the arm eventually reaches the upper limit position or the lower limit position, and its operation is regulated by the regulating means. At this time, the motor 2 enters the locked state, at which point the current value sharply increases. Therefore, if the supply current value to the motor 2 is monitored, the lock detection of the motor 2 can detect that the arm has reached the upper / lower limit position.
- step S13 the motor 2 is continuously operated for at least a predetermined time exceeding the one-way wiping time, and it is confirmed whether or not the motor lock can be detected. If the motor lock cannot be detected, a failure of the current sensor or the like may occur, so the process proceeds to step S7 to stop the motor 2 and exit the routine. On the other hand, motor lock detection was confirmed in step S13. If so, the process proceeds to step S14, and the detection of the motor lock is reconfirmed. Then, the process proceeds to step S15 to reverse the rotation direction of the motor 2.
- FIG. 8 is an explanatory diagram showing a motor control mode when the processes of steps S14 and S15 are performed.
- the arm has already reached the upper and lower limit positions, and therefore, in step S15, the motor 2 is reversed immediately after the lock is detected, as shown in FIG.
- the arm performs the reversing operation at the upper and lower limit positions, and the wiping operation can be continued without causing damage to the wiper device. Therefore, even if a failure occurs in the system of the Hall IC 17, the wiper wiping operation is continued, and the driver's view is secured.
- the motor 2 is stopped to maintain the device (steps S16 and S17).
- step S31 is a normal wiper control process, in which the arm position is detected based on the absolute position signal and the motor pulse, and the forward / reverse rotation control of the motor is performed so that the wiper blade performs the reverse wiping operation. While executing such normal control, the presence or absence of the input of the motor pulse is monitored in step S32 as in the case of the first embodiment, and if the motor pulse is input, the normal control is continued (S31). If there is no input, the process proceeds to step S33 and the following, and executes an abnormality process.
- step S33 regardless of the current rotation direction and position, the motor 2 is operated in a forward rotation direction (for example, the lower reversal position force is also the upper reversal position direction) at a constant Duty for a fixed time. .
- the operation time at this time is set to slightly longer than the one-way wiping time when the motor is operated at a constant duty.
- the arm moves to a position exceeding the upper reversing position by the processing in step S33, regardless of the current position of the arm. If the arm is in a failure state in the middle of the wiping area, the arm moves to the upper limit position in step S33. That is, the arm is moved between the upper reversing position and the upper limit position by this processing.

As a result, in step S33, the arm moves between the upper inversion position and the upper limit position, and the arm moves to near the lower inversion position.
- FIG. 10 is an explanatory diagram showing a motor control mode when the processes of steps S33 and S34 are performed.
- the motor 2 repeats forward rotation and reverse rotation for a fixed duty and for a fixed time.
- the arm performs the reversing operation near the upside-down reversing position, and the wiping operation can be continued without causing damage to the wiper device. Therefore, even if a failure occurs in the system of the Hall IC 17, the wiper wiping operation is continued, and the visibility of the driver is ensured.
- the motor 2 is stopped to maintain the device (steps S35 and S36).
- FIG. 11 is a flowchart showing the processing procedure.

While performing such normal control, the presence or absence of a motor pulse input is monitored in step S102 as in the case of the first embodiment. If there is a motor pulse input, normal control is continued (S101). If there is no input, the process proceeds to step S103 and the following to execute an abnormality process.
- step S103 the input of the absolute position signal is confirmed. If the input of the absolute position signal is confirmed in step S103, the process proceeds to step S104 to acquire the absolute position signal. After acquiring the absolute position signal, proceed to step S105 to reverse the rotation direction of motor 2. The As a result, as in the case of the first embodiment, although the motor pulse is not obtained, the arm performs the reversing operation at substantially the upper and lower reversal positions. Then, after the processes of steps S104 and S105 are repeated for a certain period of time, the motor 2 is stopped to maintain the device (steps S106 and S107).
- step S108 it is confirmed whether the lock state of the motor 2 can be detected. If the motor lock detection is confirmed, the process proceeds to step S109, and the motor lock detection is reconfirmed. Then, the process proceeds to step S110 to reverse the rotation direction of the motor 2. As a result, the arm performs the reversing operation at the upper and lower limit positions. Also in this case, after repeating the processing of steps S109 and S110 for a certain period of time, the motor 2 is stopped (steps S111 and S107).
