Abstract: A vehicle wiper device including (i) a first motor that includes a first output shaft, that rotates the first output shaft to rotate a wiper arm back and forth about a pivot point of the wiper arm, and that causes a wiper blade coupled to a leading end portion of the wiper arm to perform a back and forth wiping operation between an upper return position and a lower return position on a windshield, (ii) a second motor that changes a wiping range on the windshield by the wiper blade, (iii) a rotation angle detector that detects a rotation angle of the first output shaft, and (iv) a controller that controls the second motor according to a rotation angle of the first output shaft detected by the rotation angle detector in a state in which a broad field of view should be secured on a front passenger seat side.

Abstract: A vehicle wiper device and vehicle wiper device control method are provided that are capable of changing a position of a wiping range of a wiper arm in a manner that is less distracting.When a switch for an enlarged wiping operation has been switched ON, a microcomputer 58 performs control to change the position of a wiping range by starting rotation of an output shaft of a second motor 12 in a predetermined direction when a rotation angle of an output shaft of a first motor 11 has reached an angle corresponding to a position within a predetermined range in the vicinity of one out of a upper return position P1P or a lower return position P2P. Accordingly, when a front passenger seat side wiper blade 36 changes direction at either the upper return position P1P or the lower return position P2P, a front passenger seat side wiper arm 35 begins to extend, and the position of a wiping range of the front passenger seat side wiper blade 36 is moved upward on a front passenger seat side.

Abstract: A vehicular wiper device includes a first wiper arm, a first drive source, a rocking mechanism, a second drive source, an extension and retraction mechanism, and a control unit. A first wiper blade for wiping a surface to be wiped of a vehicle is connected to the front end of the first wiper arm. The first drive source is directly or indirectly affixed to the vehicle body. The rocking mechanism is driven by the drive force of the first drive source and reciprocates and rocks the first wiper arm. The second drive source is directly or indirectly affixed to the vehicle body separately from the first drive source. The extension and retraction mechanism is driven by the drive force of the second drive source and extends and retracts the first wiper arm in the longitudinal direction thereof. The control unit controls the drive of the first drive source and the second drive source so that the extension and retraction operation of the first wiper arm performed by the extension and retraction mechanism will correspond to the rocking operation of the first wiper arm performed by the rocking mechanism.
