System for wiping a vehicle window, the said window being equipped with a sensor, comprising a first wiper (15) which can wipe a first area of the window, including a portion (8, 8) which extends at the level of the said sensor, a second wiper (13) which can wipe a second area of the window, different from the said first area, means for activation of the said first and second wipers for the purpose of their displacement on the window, and electronic means for control of the said means for activation, characterized in that the said means for activation comprise a first motor for activation of the said first wiper, and a second motor for activation of the said second wiper, and in that the said control means are configured to activate only the said first motor when cleaning of the said portion is required.

A vehicle wiper device includes: a wiper motor; a control unit that drives the wiper motor to be reciprocally rotated and controls a rotation speed of the wiper motor; and a wiper reciprocally rotating to wipe a wiped surface of a vehicle with a blade rubber, in which a tilt direction of a lip part of the blade rubber changes when a rotation direction is reversed. The control unit accelerates a rotation speed of the wiper motor, in a first acceleration section, from 0 to a first speed which is a low speed at a first average acceleration, and to rapidly accelerate the rotation speed of the motor, in a first half of a second acceleration section, to reach a speed which is higher than the first speed and times of a second speed at an average acceleration which is twice or more of the first average acceleration.

Provided is a wiping device. The wiping device includes a pair of wiper blades that reciprocate between a lower inversion position and an upper inversion position on a wiped surface; a pair of motors that drive the pair of wiper blades respectively; and a control unit that controls the pair of motors. The control unit estimates a load of one of the motors that drives, among the pair of wiper blades, one wiper blade that moves first at operation start as a load estimation amount, and corrects the upper inversion position in a direction closer to the lower inversion position based on the load estimation amount.

A wiper device includes a wiper blade on driver seat side, a wiper blade on passenger seat side, a drive unit on driver seat side that causes wiper blade on driver seat side to perform tandem operation, and a drive unit on passenger seat side that causes wiper blade on passenger seat side to perform tandem operation. The drive units on driver and passenger seat sides transmit and receive drive information. An operation range of wiper blade on passenger seat side is set narrower and closer to an upper inversion position side than an operation range of wiper blade on driver seat side. The drive unit on passenger seat side changes operation range of wiper blade on passenger seat side toward a lower inversion position side of wiper blade on driver seat side in response to detecting, based on drive information, a failure of drive unit on driver seat side.

A wiper system for a vehicle windshield, the wiper system comprising a support assembly that is slidably movable along a guide rail, a wiper rotatably mounted on the support assembly, the wiper comprising a wiper arm and a wiper blade connected thereto, wherein the support assembly comprises a first motor mounted on a motor base, the motor base being slidably movable relative to a tilting table between at least two different positions for interacting with a first coupling element to rotate the wiper arm around a rotation axis, and for interacting with a second coupling element to adjust a length of the wiper, a second motor adapted to pivot the tilting table around a pivot axis, the tilting table being movable between at least two different positions, i.e., a non-operating position and a tilted position wherein the wiper blade is inclined thus applying a pressure on the vehicle windshield.
