The disclosure is a wiper structure. The main wiper frame includes a fixing seat. A pair of secondary wiper frames is connected to two ends of the main wiper frame. Each secondary wiper frame includes a flexible sheet. The flexible sheet is disposed with sliding troughs. A length of the sliding trough is greater than a width of the sliding trough. Multiple engaging frames are evenly disposed on each secondary wiper frame. Each engaging frame includes a pressing wing and a sliding block. The sliding block includes a neck bar with a passing diameter. The passing diameter is less than the trough width. The sliding block of each engaging frame passes through the opening and abuts against each sliding trough through the neck bar. The sliding block is slidable in each sliding trough with a change of an external force exerted on corresponding one of the secondary wiper frames.

A method of calibrating a windshield wiper system that includes moving a wiper arm, of the windshield wiper system, within at least a portion of a full range of motion defined by at least one physical boundary, determining a position of the wiper arm when it contacts the at least one physical boundary, defining, based on the determined position of the wiper arm, an operating range of motion for the wiper arm that is shorter than the full range of motion, and setting the wiper arm to operate within the defined operating range of motion.

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.

Provided are a control system of a wiper for a vehicle and a control method of the wiper for the vehicle using the same, which are capable of extending a life-span of the wiper by controlling a parking position of a unidirectional wiper. The control method includes: counting parking times at a first parking position and a second parking position of the wiper; determining whether the parking time at the first parking position of the wiper exceeds the parking time at the second parking position; and designating a parking position of the wiper according to whether the parking time at the first parking position of the wiper exceeds the parking time at the second parking position.

A vehicle wiper control apparatus monitors whether warpage occurs in a wiper strip made of a rubber-elastic material that is provided in a wiper blade. When a wiper of a vehicle is turned off and the warpage occurs in the wiper strip, the control apparatus controls the wiper mechanism to move the wiper blade to a parking position thereby preventing deformation of the wiper strip and maintaining the performance thereof.

A tool for attaching a treatment head to a wash media element of a vehicle wash component includes a nose portion and a handle portion. The nose portion is sized to pass through an opening in the wash media element. The nose portion includes a slot for receiving and retaining a base portion of the treatment head to secure it to the wash media element such that the nose portion and treatment portion are disposed on opposite sides of the wash media element.

An automated grommet installer and methods of installing a grommet. The installer and methods are capable of seating a grommet in an aperture of a window and facilitating correct alignment of the grommet within the window. Grommets are used to support and seal around a window wiper attached to a window. Typically, grommets are asymmetrical to match the curvature of the window. Embodiments of the described installer maintain grommet orientation while inserting the grommet in the window, quickly and efficiently installing the grommet. In embodiments the installer includes a system for identifying an incorrectly loaded grommet prior to installation and alerting an operator. In other embodiments, the installer includes a positioner that positions the grommet proximate to the window for installation and a gripper having one or more fingers reach through the window aperture, engage the grommet, and draw it into position, seated in the window.
