Enhanced wiper assembly
A wiper assembly for a window of a vehicle and a method of cleaning a window are provided. The wiper assembly includes a wiper blade having a fluid extraction opening, a fluid discharge outlet remote from the wiper blade and a fluid tight conduit connecting the fluid extraction opening to the fluid discharge outlet. The wiper assembly may further include a suction pump configured to draw air and water into the fluid extraction opening and through the fluid tight conduit of the wiper assembly, thereby reducing the amount of water left of the window following wiping and improving visibility for the driver.
BRUSHLESS MOTOR, WIPER APPARATUS, MOTOR APPARATUS AND CONTROL METHOD FOR MOTOR APPARATUS
A brushless motor (18) which supplies currents to coils (U1, U2, V1, V2, W1, and W2) and rotates a rotor (27), the brushless motor comprising a control apparatus (37) which switches and selectively executes: first energization control to start energization to the coils (U1, U2, V1, V2, W1, and W2) at first timing, and to continue the energization for a first period to control the rotation number of the rotor (27); and second energization control to start energization to the coils (U1, U2, V1, V2, W1, and W2) at second timing advanced by an electric angle with respect to the first timing, and to continue the energization for a second period longer than the first period to control the rotation number of the rotor (27).

CONTROL FOR PASSIVE WIPER SYSTEM
A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

BRUSHLESS WIPER MOTOR
Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

Windshield cleaning system and method
Disclosed herein is a windshield cleaning system including a computer in electronic communication with a windshield wiper controller, an image device, a fluid applicator, and a fluid heater. The system captures and compares a pre-spray image with a post-spray image, the post spray image acquired after actuating the fluid applicator and before actuating the windshield wiper. The comparison is performed by the computer to determined potential conditions with the windshield cleaning system.
METHOD, DEVICE AND APPARATUS FOR CONTROLLING WINDSCREEN WIPER, AND VEHICLE
A method, a device, and an apparatus are provided for controlling a windscreen wiper. The apparatus may be a vehicle. The method may include: acquiring environmental information at a vehicle location of the vehicle, the environmental information at the vehicle location of the vehicle including environmental temperature; determining whether the vehicle is in a service state or an out-of-service state; determining whether the environmental temperature is less than or equal to a preset temperature value according to the environmental temperature; and when the vehicle is in the out-of-service state and the environmental temperature is less than or equal to the preset temperature value, controlling the windscreen wiper of the vehicle to be raised in a direction away from a windscreen of the vehicle.
GRAVITY BASED VEHICLE CAMERA CLEANING SYSTEMS AND METHODS
Methods and systems are disclosed for cleaning a rear view vehicle camera. An example vehicle camera cleaning system includes a camera, a blade for cleaning a lens of the camera, a fluid reservoir for dispensing fluid using gravity via a one-directional gateway valve, and an actuator for moving the blade vertically across the lens, wherein the fluid reservoir dispenses fluid responsive to actuation of the blade.
