PROBLEM TO BE SOLVED: To provide a wiping range expansion wiper device which executes expansion of a wiping range according to a view angle of a driver and a control method of a wiping range expansion wiper device.SOLUTION: A microcomputer 58 calculates magnification of a front passenger seat side wiper arm based on change of a view angle of a driver. The microcomputer 58 rotates an output shaft of a second motor 12 in normal rotation at a rotation angle according to the calculated magnification when an output shaft of a first motor 11 is rotated in normal rotation and a front passenger seat side wiper blade 36 is moved from a lower inversion position P2P to an upper inversion position P1P, then moves a fifth axis line L5 which is a fulcrum of the front passenger seat side wiper arm 35 in an angle direction on an upper side of the front passenger seat side on a windshield glass 1, then rotates the output shaft of the second motor 12 in reverse rotation at a rotation angle according to the magnification and disposes the fifth axis line L5 to an original position until the front passenger seat side wiper blade 36 reaches the upper inversion position P1P.SELECTED DRAWING: Figure 1
【課題】払拭範囲の拡大を運転者の視野角に応じて実行する払拭範囲拡大ワイパ装置及び払拭範囲拡大ワイパ装置の制御方法を提供する。【解決手段】マイクロコンピュータ58は、運転者の視野角の変化に基づいた助手席側ワイパアームの拡大率を算出する。また、マイクロコンピュータ58は、第1モータ11の出力軸を正回転させて助手席側ワイパブレード36を下反転位置P2Pから上反転位置P1Pへ移動させている間に、第2モータ12の出力軸を算出した拡大率に応じた回転角度で正回転させて、助手席側ワイパアーム35の支点である第5軸線L5をウィンドシールドガラス1上の助手席側上方の角方向に移動させ、助手席側ワイパブレード36が上反転位置P1Pに達するまでに第2モータ12の出力軸を拡大率に応じた回転角度で逆回転させて第5軸線L5の位置を元に戻す。【選択図】図1
