Cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of a driving environment sensor, and device for sensing the environment and method
A cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of an environment sensor, including at least one movable wiper blade, which is arranged so as to wipe off foreign matter such as water or dirt on the cover by movement along the cover. For this purpose, the wiper blade touches the cover for example with one or multiple rubber lips. The wiper blade is positioned in an inclined manner with respect to a direction of movement of the wiper blade and is thus movable in such a way that a force exerted by the moved wiper blade on the foreign matter has a component in the direction of the force of gravity. Also described is a related device for sensing the environment as well as a method for cleaning a cover.
ANTI-FOGGING STRUCTURE FOR WINDOW GLASS
A defogging structure of a windowpane of a movable body in which an information acquisition device configured to acquire information from an exterior of the movable body by at least one of emitting light or receiving light can be arranged in an interior of the movable body, the defogging structure including: a windowpane having an information acquisition area through which at least one of light emitted by the information acquisition device or light to be received by the information acquisition device passes; a defogging sheet including a resin film and a defogger, the defogging sheet being adhered to the information acquisition area of the windowpane; and a transparent resin adhesive layer that allows the resin film of the defogging sheet to be adhered to the windowpane, wherein a resin constituting the transparent resin adhesive layer has a Tg of −20° C. to −50° C., and a shear storage modulus of 0.5×10.sup.5 Pa to 2.0×10.sup.5 Pa.
System for cleaning an optical sensor, assembly comprising such a system, and associated motor vehicle
The present invention relates to a system (1) for cleaning an optical sensor (3), notably of a motor vehicle, comprising: —an element (5) for spraying a cleaning liquid, —a tank (7) of cleaning liquid fluidically connected to the element (5) for spraying cleaning liquid, —a pump (9) configured to pump the cleaning liquid from the tank (7) to the element (5) for spraying the cleaning liquid, the system (1) also comprising a containment wall (11) for the cleaning liquid, which is movable between a retracted position in which the containment wall is configured to be positioned outside the field of view of the optical sensor (3) and a cleaning position in which the containment wall (11) is configured to be positioned in front of the optical sensor (3) so as to define a collection vessel (13) for the cleaning liquid, and in that it comprises an evacuation pipe (15) for the cleaning liquid that is connected both to the collection vessel (13) in the cleaning position and to the tank (7) of cleaning liquid.
Apparatus for cleaning object surface
Apparatus for cleaning object surface, wherein the apparatus for cleaning object surface is adapted to be arranged to or accommodate an object, wherein the apparatus is arranged to supply cleaning fluid to the object surface, wherein the apparatus comprises a body provided with an opening with a circumferentially extending flexible part, flange or lip partly covering the object surface in circumferential direction thereof and in engagement with the object surface with a pretension force, and wherein the apparatus is arranged to supply cleaning fluid interior of the body and the flexible part, flange or lip is arranged to bend away from the object surface when subjected to cleaning fluid supplied interior of the body.
Moving body control apparatus
There is provided with a moving body control apparatus. An image capturing unit captures a periphery of a moving body through a transmitting portion. A heater is capable of heating the transmitting portion. An air-conditioning unit switches an air-conditioning state in the moving body between an inside air circulation state and an outside air introduction state. A control unit controls the heater. An ambient temperature detection unit detects an ambient temperature. The control unit starts the operation of the heater when the ambient temperature is not more than a predetermined temperature threshold. The predetermined temperature threshold of the case in which the air-conditioning state is set to the inside air circulation state is higher than the predetermined temperature threshold in the case in which the air-conditioning state is set to the outside air introduction state.
Automated debris removal
A system for automated detection and removal of visual obstructions such as debris, fumes, or mist from the view zone of an imaging device. An autodetection algorithm runs on incoming visual data from a data acquisition (DAQ) system to determine if a visual obstruction is present. A controller initiates a dry-cleaning dual cycle (DCDC) run including a wet clean cycle and a dry clean cycle. During the wet clean cycle, a base fluid mist is distributed onto the view zone. Subsequently during the dry clean cycle, compressed air is distributed onto the view zone.
ADAPTIVE WIPING ELEMENTS FOR OPTICAL INTERFACES BASED ON VISUAL FEEDBACK
A method for detecting non-rain and/or non-snow particles movement towards an optical interface is disclosed. The method comprises: receiving one or more images from one or more imaging sensors of the vicinity of the optical interface, of particles movement towards the optical interface; analyzing the one or more images to detect non-rain and/or non-snow particles movement towards the optical interface and distinguish between rain and/or snow particles and the non-rain and/or non-snow particles movement towards the optical interface; and controlling one or more wiping elements activation based on the analyzed one or more images and removing the non-rain and/or non-snow particles from the optical interface.
Sensor assembly with a non-contact surface cleaning system for cameras, sensors, lidar and the like
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.

Vehicle camera lens dirt protection via air flow
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.
