An autonomous driving sensor cleaning system for a vehicle includes a rotatable cover unit configured to surround a sensor such as a cylindrical sensor. The system also includes a cleaning unit coupled to the cover unit to transmit a rotation driving force to the cover unit and configured to clean the cover unit by friction while being rotated in a direction opposite to the rotation direction of the cover unit. The system also includes a rotation driving unit coupled to the cleaning unit and configured to transmit the rotation driving force to the cleaning unit.

Vehicle windshield wiper cowl assembly comprising a protective cowl panel adapted to be mounted on the bodywork of a vehicle at the lower end of the vehicle's windshield, the cowl panel having a shaft opening for the pivot shaft of a windshield wiper, the shaft opening having a circumferential border area with a front side and a back side, wherein the border area front side defines a circumferential bordering surface, and a hose connector having a back face and a front face, wherein the hose connector is set into the cowl panel's shaft opening so that the hose connector is bordered by the shaft opening's circumferential border area. The front face of the hose connector is flush with the circumferential bordering surface defined by the border area front side.

An airflow diverting apparatus for facilitating heating a windshield wiper of an automobile includes a duct which is positionable on a dashboard of the automobile over a defroster vent of the automobile.
