To provide a wiper device and a wiper control device, and a wiper control method which performs control corresponding to various states of a wiping surface, suppresses over-run of a blade and prevents interference to a stick slip and an A pillar.SOLUTION: A wiper device includes a wiper blade which performs a reciprocal wiping movement between upper and lower inversion positions on a glass surface, a motor 2 for driving the wiper blade and a wiper control device 21 which controls movement of the motor. Therein, the wiper control device 21 is provided with a load detection part 23 which detects a load of the motor, a point value comparator 27 which compares a detected value of the load and a threshold and an inversion position correction part 28 which controls an inversion position of the wiper blade based on the comparison result. The inversion position correction part 28 properly controls the inversion position of the wiper blade corresponding to a load which changes in accordance with the state of the glass surface and, when there is such a danger as to over-run the upper inversion position, controls the inversion position so as to come to the own side than usual to prevent over-run of the blade.SELECTED DRAWING: Figure 4

    【課題】払拭面の様々な状態に対応した制御を行い、ブレードのオーバーランを抑制し、スティックスリップやAピラーへの干渉を防止する。【解決手段】ガラス面上の上下反転位置間にて往復払拭動作を行うワイパブレードと、ワイパブレードを駆動するためのモータ2と、モータの動作を制御するワイパ制御装置21と、を有するワイパ装置において、ワイパ制御装置21に、モータの負荷を検出する負荷検出部23と、検出された負荷の値と閾値とを比較するポイント値比較部27と、比較結果に基づきワイパブレードの反転位置を制御する反転位置補正部28と、を設ける。反転位置補正部28は、ガラス面の状態に応じて変化する負荷に対応してワイパブレードの反転位置を適宜制御し、上反転位置をオーバーランしてしまうおそれがある場合、反転位置を通常よりも手前となるよう制御し、ブレードのオーバーランを防止する。【選択図】図4
