An electromagnetic wiper system for a windshield of a vehicle includes a linear actuator, a wiper-arrangement, and control circuitry. The linear actuator includes at least one guide rail having permanent magnets and an electromagnetic moving block. The electromagnetic moving block includes at least one perforation that surrounds the at least one guide rail and at least one electromagnetic coil that surrounds the at least one perforation. The wiper-arrangement includes a wiper arm and a wiper blade, wherein at least the wiper arm is coupled to the electromagnetic moving block. The control circuitry controls a linear motion of the electromagnetic moving block along the at least one guide rail to steer the wiper arm that is coupled to the electromagnetic moving block back and forth across a length of the windshield to the windshield, wherein the electromagnetic moving block induces minimal friction during the linear motion.

A vehicle is provided to include a wiper, a wiper driver that is connected to the wiper and configured to provide a driving force for rotation of the wiper, and a multi-function switch that is configured to receive a user command to turn the wiper driver on or off. A controller is configured to adjust a position of the wiper to enter a parking state after a preset time when a local interconnect network (LIN) communication system enters a limp home mode and the rotation of the wiper is stopped by a signal for turning off the wiper driver.

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.

When a first driver setting mode indicates an “OFF mode” or an “AUTO mode,” a VP accepts a light operation mode request from an ADK. When an operation is performed by a user, the VP changes an operation mode of a headlight in accordance with the operation by the user. When the operation by the user has not been performed, the VP changes the operation mode of the headlight in accordance with the light operation mode request.

Turning angles of an output shaft of a wiper motor are detected by a turning angle sensor. In a case in which a wiper switch is switched off, a wiper control circuit performs control to stop a wiper blade at a stowed position, which is a stop reference position, on the basis of a position of the wiper blade calculated from a detected turning angle. If the wiper blade stops at a position that is different from the stop reference position, the wiper control circuit sets this stop position as a new stop reference position. In a case in which the wiper switch is subsequently switched on again, the wiper control circuit performs control to move the wiper blade from the new stop reference position.

In a driving apparatus (10) in which a position of a rotating shaft (27) of an electric motor (16) in a direction of an axis (B1) is determined, the driving apparatus (10) has: a stopper (77) which determines a position of the rotating shaft (27) in the direction of the axis (B1), and a terminal holder (31) which holds a first terminal for supplying an electric current to the electric motor (16), wherein a layout region of the stopper (77) in the direction of the axis (B1) and a layout region of the terminal holder (31) in the direction of the axis (B1) are overlapped with each other.

A semiconductor device including an abnormality detection section that detects an abnormality occurring in a moving body that moves along a specific path on a surface of a specific object; a position detection section that detects a position of the moving body as an abnormality occurrence position, in a case in which the abnormality detection section has detected an abnormality, and that stores abnormality occurrence position information expressing the abnormality occurrence position in a storage section; and a moving body controller that controls an adjusting section to adjust at least one of a force with which the moving body presses against the specific object, or a position of the moving body in a direction intersecting the surface of the specific object, based on a detection result detected by the abnormality detection section and the abnormality occurrence position information.

An embodiment vehicle includes a rain sensor configured to generate a splash signal in response to detecting rain greater than or equal to a predetermined amount, a wiper driver configured to operate a wiper based on the splash signal, a first controller configured to transmit the splash signal to the wiper driver, and a second controller configured to receive the splash signal from the first controller, generate a control signal based on the splash signal, and operate at least one electronic device based on the control signal.

Apparatuses and methods for removing ice from a windshield. A windshield wiper includes a wiper assembly, a scrubber assembly, and an engaging assembly. The wiper assembly includes a wiper support structure and a wiper blade attached to the wiper support structure. The scrubber assembly includes a scrubber support structure, an elongated scrubber element and a motor. The scrubber element is movably attached to the scrubber support structure and extends between a first end and a spaced apart second end along a central longitudinal axis. The scrubber element can have a hardness value sufficient to remove ice from the windshield. The motor is mounted to the scrubber support structure and is engaged with the scrubber element to move the scrubber element to remove ice. An engaging assembly can be coupled with the wiper assembly and the scrubber assembly to raise and lower the scrubber assembly with respect to the wiper assembly.

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.
