Abstract: Provided is 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.
