A wiper control method and a wiper control device are provided. An arm falling position for stopping wiper arms for a predetermined time is set above a lower reversal position. When the wiper arms stopped on the side of an upper reversal position with respect to the arm falling position, such as a service position, are moved to a storage position set below the lower reversal position, or when a wiping operation is to be performed again, the wiper arms are temporarily stopped for the predetermined time at the arm falling position. Then, after the predetermined time elapses, the wiper arms are moved to the storage position in the case of a storage operation, and moved to the upper reversal position in the case of restarting, and then the normal wiping operation is performed.

Wiper control method and wiper control device

When an ECUfor wiper motor detects that a SP operation has been carried out in the midst of swinging motion of a wiper blade, the ECUfor wiper motor outputs a motor stopping signal to an ECUfor washer pump. When the ECUfor washer pump receives the motor stopping signal, the ECUfor washer pump stops a washer pumpeven if an injection switch for jetting out washer fluid is on. In this manner, when a wiper blade is stopped from being swung for replacement of the wiper member, the pump for causing washer fluid to jet out is stopped. Therefore, it is possible to prevent the waste of washer fluid, and to further save washer fluid.

Wiper control apparatus

When a wiper is started, a wiper arm is moved at first in the backward path direction (S). If a motor is locked (S) before an original point position signal is outputted, a reciprocating operation for moving the wiper arm temporarily in the forward path direction and then moving the wiper arm again in the backward path direction is performed (S-S, S). When an absolute position signal is not outputted even after repeating the reciprocating operation a plurality of times (S) and the original point position cannot be recognized (SS), the motor is not forced furthermore but stopped (SEND) On the other hand, if the motor is not locked when the wiper arm is moved in the backward path direction (S) and the original point position can be recognized (S, S), wiping control is performed (S) by calculating the wiper arm position based on the original point position and the motor rotation pulse.

Wiper control method and wiper control system

The control device for a closure member of a vehicle according to the present invention comprises: estimated load calculation means () for obtaining an estimated load from a rotation speed, acceleration, and drive voltage of a DC motor () for driving a closure member (); motor torque calculation means () for calculating a motor torque from the rotation speed and drive voltage of the motor; reference torque calculation means () for calculating a reference torque based on a stationary state of the motor torque; and pinching determination means () for determining a pinching of an object based on the estimated load, motor torque and reference torque, wherein the pinching determination means determines that there is no pinching when at least one of the estimated load and the motor torque is below the reference torque even when the estimated load is greater than a prescribed threshold value.
