Method and apparatus are disclosed for vehicle washer fluid delivery diagnostics and cleaning. An example vehicle includes an engine, a windshield, a camera for capturing images of the windshield, a nozzle, and a washer fluid controller. The washer fluid controller is to instruct the nozzle to spray washer fluid responsive to detecting the windshield is obstructed based upon a first image, determine whether the nozzle emitted a target spray based upon a second image, and pump pressurized air through the nozzle upon detecting the target spray was not emitted and the engine is off.

The invention relates to a cleaning device for cleaning an optical device of a motor vehicle, wherein the cleaning device features at least two cleaning units and at least one holder upon which the cleaning units are arranged. Each cleaning unit has a drive part and a cleaning part, wherein the drive part features an electroactive polymer and can at least partly move the cleaning part. The holder on which the cleaning units are arranged can move between a working position, in which the cleaning units are positioned relative to the optical device in such a manner that the drive part can move the cleaning parts across a surface of the optical device that is to be cleaned, and a rest position, in which the cleaning units are positioned away from the optical device. The cleaning device is embodied in such a manner that each cleaning part of the cleaning units is moved over a subarea assigned to it of the surface to be cleaned, wherein the subareas can at least partly overlap.

The present disclosure provides an optical sensor having constant sensitivity regardless of changes in temperature. The optical sensor may include a light emitting device configured to emit light; a light receiving device configured to receive the light emitted from the light emitting device, and to output current based on an intensity of the light; a temperature sensor coupled with the light emitting device, and having electrical resistance varying with temperature; and a microcontroller including a first channel for supplying first current directly to the light emitting device, a second channel for supplying second current to the light emitting device via the temperature sensor, and a third channel for receiving the current output from the light receiving device.

In a brushless wiper motor, a rotor (33) is rotatably provided inside a stator (32) provided with a coil (32b), one end side of a rotation shaft (34) in the axial direction is fixed to the axial center of the rotor (33), a worm (35) is provided on the other end side of the rotation shaft (34) in the axial direction, the first and second bearings (36, 37) are respectively provided on one end side of the rotation shaft (34) in the axial direction and the other end side of the rotation shaft (34) in the axial direction than the worm (35) of the rotation shaft (34), the rotation shaft (34) is rotatably supported by only the first and second bearings (36, 37), and with the position of the first bearing (36) being defined as a reference position, a length thereof in the axial direction to the second bearing (37) is longer than a length thereof in the axial direction to the rotor (33). Since a commutator and other parts are not provided on a free end side of the rotation shaft (34), it is possible to provide a brushless wiper motor reduced in length of the rotation shaft (34), and reduced in inertial mass of the free end side of the rotation shaft (34).
