An automobile vehicle wiper arm system includes a wiper arm base rotatably connected to a fixed structural member. A wiper arm extension is slidably disposed to the wiper arm base during wiper arm base travel about an arc of travel. A motion link is rotatably connected to the wiper arm extension and is rotatably connected to the fixed structural member. The motion link induces the wiper arm extension to outwardly displace and inwardly displace opposite to the outward displacement during wiper arm base rotation about the arc of travel. A wiper blade is connected to the wiper arm extension and traverses an oval-shaped travel arc along a vehicle windshield by the slidable displacement of the wiper arm extension during wiper arm base rotation. A linkage group connects the wiper arm extension to a wiper motor with rotation of the wiper arm base induced by operation of the wiper motor.

A motor and a brushless wiper motor are provided. The motor (2) includes: a stator (8); coils (24); a shaft (31); a rotor core (32); magnets (33) which are disposed on an outer peripheral surface (32b) of the rotor core (32) and a radial thickness of which at end portions (33s) on both sides in the circumferential direction around the rotation axis is smaller than a radial thickness in a circumferential intermediate portion; and salient poles (35) that are formed between magnets (33) adjacent in the circumferential direction of the outer peripheral surface (32b) of the rotor core (32) and protrude radially outward from the end portions (33s) of the magnets (33) in the circumferential direction. The width dimensions of the salient poles (35) in the radial direction being set to 40 or less in a form of an electrical angle.

A computer implemented method for operating a wiper system of a sensor enclosure. The wiper system can be configured to receive a camera operating information from one or more cameras. The one or more cameras can be determined to be in an exposure mode based on the camera operating information. A first speed of one or more wipers can be adjusted such that the one or more wipers are not in field of views of the one or more cameras while the one or more cameras are in the exposure mode.

A camera device for a motor vehicle includes a camera module with a module body having at least one aperture, a sensor adapted to detect electromagnetic radiation of a spectral range and arranged within the module body, and an optical element mounted to substantially cover, fill or close the aperture, a deployment system adapted to move the camera module between a retracted state, in which at least the optical element is arranged within the cavity of the vehicle body with the outer surface of the camera module body being generally flush with the exterior of the vehicle body, and a deployed state, in which the camera sensor is operable and at least the optical element protrudes from the vehicle body, and cleaning means for cleaning the optical element at least during movement of the camera module between the retracted state and the deployed state.

An apparatus includes a base, a cylindrical sensor window fixed to the base, and a helical cleaning member movable between a retracted position in the base and an extended position extending around the sensor window. The cleaning member includes an outlet directed at the sensor window when the cleaning member is in the extended position.

A system includes a processor and a memory storing instructions executable by the processor to predict a path of a liquid droplet on a surface, and then, actuate one or more vehicle components based on the path.

A system includes a processor and a memory. The memory stores instructions executable by the processor to detect an object exterior to a vehicle, and to actuate a fluid dispenser device based on an opacity of a window and a location of the detected object.

A system includes a computer programmed to actuate a first nozzle to emit air continuously at a camera, and actuate a second nozzle to simultaneously emit air intermittently at a precipitation sensor. The system may include a camera, a precipitation sensor coupled to the camera, the first nozzle aimed at the camera, the second nozzle aimed at the precipitation sensor, and the computer in communication with the first and second nozzles.

A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.
