A sensor assembly includes a sensor and a cover disposed adjacent to the sensor to protect the sensor. The cover has an inner cover surface and an outer cover surface opposite the inner cover surface. The inner cover surface faces the sensor, and the outer cover surface faces away from the sensor. The cover has a first end wall and a second end wall apart from the first end wall along a first direction. The sensor assembly includes a cleaning system having a wiper movable along the outer cover surface of the cover in the first direction to clean to the outer cover surface. The wiper is at least partly made of a wiper material, and the wiper material includes a hydrophilic material to facilitate removal of water from the outer cover surface of the cover.

Systems and methods for random vehicle movement to prevent theft are disclosed. The vehicle system may automatically reposition to make it seem like the user is home and to reduce battery drain and flat spots on the tire. The system may randomize the start time based on the preferences of the user. At the randomly decided time, the vehicle may start up on its own and reposition itself. In addition, the system may learn a driving behavior pattern of the vehicle via machine learning based on driving behavior associated with the vehicle, such that the vehicle may perform vehicle movement based on the learned driving behavior pattern.

A system for mitigating contamination of a lens of an exterior vehicular camera includes a passive air flow device disposed at the vehicle and configured to passively direct air flow across an outer surface of a lens of the camera to establish a passive air stream curtain. An active air flow device is operable to actively propel air across the outer surface of the lens of the camera to establish an active air stream curtain. A control is operable to activate and deactivate the active air flow device. When the vehicle is driven at a speed of travel below a threshold level, the control activates the active air flow device to actively propel air across the outer surface of the lens of the camera. When the vehicle is in motion, the passive air stream curtain deflects polluting particles away from the outer surface of the lens of the camera.

The invention relates to a device for cleaning a sensor (2) of an optical detection system for a motor vehicle, comprising a fluid distribution set (3) for distributing fluid onto said sensor under the control of operating instructions issued by a control module (6). According to the invention, the control module is configured to generate an information message (M1) about the need for the sensor to be cleaned and to receive a control instruction from a vehicle occupant authorizing the cleaning operation.

A method of assembling a vehicle cleaner nozzle provided in a vicinity of a leading end of a piston accommodated to be movable forward and backward with respect to a cylinder so as to inject a cleaning medium on an object to be cleaned which is mounted on a vehicle includes: assembling a nozzle chip to a housing along a first direction so as to form a feedback flow path for swinging and injecting the cleaning medium by accommodating the nozzle chip in an interior of the housing; and assembling the housing in a state where the housing accommodates the nozzle chip to a holder supported by the piston along the first direction.

The present invention relates to a cleaning system for equipment of a motor vehicle comprising at least one wiper element; a mechanism for driving the wiper element, comprising an electric motor; a device for spraying a cleaning liquid comprising a hydraulic pump and at least one spray nozzle, in which the spraying device comprises a hydraulic valve to allow the supply of liquid to the at least one spray nozzle, said hydraulic valve comprising a movable plunger to allow or prevent the passage of the cleaning liquid, said movable plunger being movably connected to a movable element of the drive mechanism so that the position of said plunger is selected by a movement of said movable element of the drive mechanism.

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 droplet sensor has an optical cover with a curved surface that forms a part of a spheroid, a light source positioned at a first focal point of an ellipse, the first focal point facing the curved surface, and a photodetector positioned at a second focal point of the ellipse. The ellipse has an eccentricity determined such that the curved surface has an effective detection area that satisfies conditions for total internal reflection at an interface with a gas and that does not satisfy the conditions for total internal reflection at an interface with a liquid.

A wiper device that includes: a first control section that, during intermittent operation, controls power supply to a drive source such that a wiper blade wipes to-and-fro between a first return position and a second return position on a windshield and stops moving for a predetermined duration at the first return position, and that performs position retention control that controls power supply to the drive source such that the stopped wiper blade is retained at a position at which the wiper blade is stopped; and a second control section that suspends the position retention control by the first control section in a case in which a current flowing in the drive source is detected to have increased by a predetermined value or greater while the wiper blade moves toward the first return position within a predetermined region in a vicinity of the first return position.
