A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.

In an opposite arrangement-type wiper system, an operation range 5b of an assistant driver's seat-side wiper blade 1b is set in such a way as to be narrower than an operation range 5a of a driver's seat-side wiper blade 1a and to overlap with the operation range 5a only partially. A lower side turn point Lb of the wiper blade 1b is set near an outer periphery R of the operation range 5a and an overlapping operation range 6c is formed between the operation ranges 5a and 5b. A normal stop position of the wiper blade 1b at the time when the wiper system is not running is set on the side of an upper side turn point Ub. While being arranged opposite from each other, the wiper blades 1a and 1b operate in tandem in the same direction when moving back and forth for wiping.

A heated windshield wiper system includes a vehicle has a wiper motor and a windshield. The wiper motor is electrically coupled to the vehicle. A pair of windshield wipers is provided and each of the windshield wipers is movably coupled to the vehicle. Each of the windshield wipers is operationally coupled to the wiper motor. The wiper motor selectively urges each of the windshield wipers across the windshield. Thus, each of the windshield wipers may clear the windshield. A heating unit is coupled to each of the windshield wipers. The heating unit is electrically coupled to the wiper motor. The heating unit selectively heats each of the windshield wipers. Thus, each of the windshield wipers may melt snow and ice from the windshield.

A wiper system for clearing a surface of a dome includes a plurality of wiper blades that are configured to move around a circumference of the dome. Rotation of the wiper blades in a first direction around the circumference of the dome deploys the wiper blades into an upright position and rotation of the wiper blades in a second direction opposite the first direction stows the wiper blades into a collapsed position.

A wiper system for a vehicle is provided. The wiper system includes a driving assembly. The wiper system further includes a supplementary wiper having a first end that is coupled to a first pivot point of the driving assembly. When the wiper system is activated, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position to an extended position. The supplementary wiper is configured to be statically disposed at the extended position to prevent water from passing over one of two A-pillars of the vehicle to a side window of the vehicle. When the wiper system is deactivated, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.
