A wiper system performs operation control on wiper driving electric motors and based on position information about wiper blades and attached to pivot shafts, wherein a learning mode in which a position of the wiper blades is learned to correct blade position information is executed after the wiper blades are attached to the pivot shafts, respectively. In the learning mode, the wiper blades are moved to a prescribed position such as a lower retracted position, and that the wiper blades are located in the prescribed position is detected by such means as a sensor, a video image, and contact with a jig. If the wiper blades are detected to be in the prescribed position, the blade position information is corrected to a value corresponding to the position.

A system includes an optical fiber embedded in a windshield. The system includes a reflector embedded in the windshield and oriented to reflect light to a first end of the optical fiber. The system includes a sensor oriented to receive light from a second end of the optical fiber.

The invention relates to a method for determining the wiping use of a wiper blade (14) pertaining to a wiper system (10) used to wipe a window pane (12) of a motor vehicle, with a view to replacing said wiper blade once it exceeds a determined wear threshold, the wiper blade carrier (16) being movable between a position of use, called a service position, and a maintenance position, said method being characterised in that it successively comprises: a step a) of acquiring at least one data element representing the presence of the wiper blade (14) in the maintenance position; a step b) of determining the replacement of the wiper blade with a new wiper blade; and a step (c) of estimating the wiping use of the new wiper blade.

A windshield wiper system (WWS) is provided and includes a brushless direct current (BLDC) motor with a motor output shaft gear, a gear train and an internally cut sector gear. The gear train includes a first gear, which has a first diameter and engages with the motor output shaft gear, and a second gear, which has a second diameter that is shorter than the first diameter and rotates with the first gear. The internally cut sector gear is coupled with an output shaft and formed to define an internal geared groove that engages with the second gear.

A motor with speed reduction mechanism is provided with an anti-scattering cover 80 for grease, which holds grease applied to a mating part MT where a worm 36b and a worm wheel 40 are in engagement with each other, the anti-scattering cover 80 for grease is provided and closer to an opening 32c than the worm wheel 40 along an axial direction of the worm wheel 40. The anti-scattering cover 80 for grease has: a first wall 81 extending from the opening 32c toward a bottom 32a and formed between the worm 36b and a side wall 32b of a speed reduction mechanism housing unit 32; and a second wall 82 extending in a direction intersecting with the first wall 81 and covering the mating part MT from the same side as the opening 32c along the axial direction of the worm wheel 40. The first wall 81 and the second wall 82 of the anti-scattering cover 80 for grease hold grease attached to the worm 36b, thereby preventing exhaustion of grease applied to the mating part MT where worm 36b and the worm wheel 40 are in engagement with each other.
