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.

In a rainfall amount measurement apparatus, raindrop amount information corresponding to an attachment amount of raindrops attached to an outer wall surface of a windshield of the vehicle in a measurement period is acquired based on an output of a detector configured to generate an output corresponding to the attachment amount of raindrops. The raindrop amount information is used to set a wiping interval in a wiper wiping the raindrops attached to the outer wall surface. The measurement value of a rainfall amount per unit time is calculated based on the raindrop amount information, and outputted to an outside of the vehicle.

A control section is configured to perform rotation control of a wiper motor that causes a wiper blade to perform a wiping operation over a windshield, and a test unit is capable of communicating with the control section at a characteristic communication speed of the control section, and employs a specific communication with the control section at the characteristic communication speed to enable testing of the control section and the wiper motor by communication at a test communication speed of not less than the characteristic communication speed.

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.

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.

A wiper operation system for a construction machine, enabling a plurality of wiper operating modes set for the operation of the wiper device to be easily checked and being capable of preventing erroneous selection of the wiper operating mode, includes a display, an operation reception unit that receives a mode selection operation for selecting one wiper motion mode from among a plurality of wiper motion modes, and a wiper control section that makes the wiper device perform a motion in the selected wiper motion mode. The display includes a wiper motion display unit performing a display of a plurality of icons corresponding to a plurality of wiper action modes respectively, and an identification display enabling the icon of the selected wiper action mode to be identified.

This disclosure details vehicle windshield wiper systems and methods for controlling windshield wipers in a manner that reduces the buildup of frozen precipitation on the vehicle windshield. In exemplary embodiments, a windshield wiper can be automatically commanded to wipe a windshield at a pre-calculated wiping interval rate when precipitation is detected on a vehicle surface, a vehicle ambient temperature is below a predefined ambient temperature threshold, and a vehicle interior temperature exceeds a predefined interior temperature threshold.

A windshield wiper system (WWS) is provided and includes a wiper blade, a motor assembly and a control system. The wiper blade includes a tip. The motor assembly is configured to drive the wiper blade in a sweep pattern across a windshield. The control system is configured to control the driving of the wiper blade by the motor assembly in accordance with positions of the tip of the wiper blade.

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 wiper device including a wiper motor that includes a rotor and a coil to generate a rotating magnetic field, and that causes a wiper blade to perform a wiping operation by rotating the rotor according to the rotating magnetic field, a drive section that drives rotation of the wiper motor by performing current switch-on in the coil so as to generate the rotating magnetic field, and a controller that controls the drive section by a timing for current switch-on in the coil based on at least a rotation position of the rotor.
