摘要： A device and method for protecting an optical sensor of a vehicle are disclosed, wherein the sensor is protected from environmental pollutants which may adhere to an optical surface of the sensor if the sensor is exposed to them, and wherein the environmental pollutants are kept away from the sensor by an ultrasonic cleaning of the sensor surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device into the air to provide a protection zone around the optical surface of the sensor such that a contact of the optical surface with the environmental pollutants is avoided, wherein the environmental pollutants are moved and/or destroyed in the air away from the sensor if they enter the protection zone), and wherein the protection zone provides a contactless cleaning of the sensor.

摘要： An optical device includes an outermost layer lens, a housing, a vibrator, an inner layer lens, a fixing portion, and a position adjustment portion. The vibrator vibrates the outermost layer lens held by the housing. The inner layer lens faces the outermost layer lens. The fixing portion fixes the inner layer lens to the housing. The position adjustment portion is provided in the fixing portion to adjust alignment of the inner layer lens with respect to the outermost layer lens. The fixing portion is connected to a portion of the housing that is a node of vibration by the vibrator.

摘要： The invention proceeds from a cleaning procedure for a cleaning system (12a; 12b; 12c; 12d), in particular wash system, of an at least partially automated mobile vehicle (10a; 10b; 10c; 10d), for cleaning at least a partial area (18a; 18b; 18c; 18d) of a vehicle window (14a; 14b; 14c; 14d) of the vehicle (10a; 10b; 10c; 10d) and for cleaning at least a partial area (22a; 22b; 22c; 22d) of a field of view (16a; 16b; 16c; 16d) of a, in particular optical, driving assistance sensor (20a; 20b; 20c; 20d) of the vehicle (10a; 10b; 10c; 10d), such as a LiDAR sensor, a camera sensor, a video sensor or the like, wherein the cleanable partial areas (18a; 18b; 18c; 18d, 22a; 22b; 22c; 22d) of the field of view (16a; 16b; 16c; 16d) and the vehicle window (14a; 14b; 14c; 14d), at least partially overlap.
It is proposed that when the cleaning system (12a; 12b; 12c; 12d), in particular the wash system, be manually initiated to clean the vehicle window (14a; 14b; 14c; 14d) during an at least partially automated driving operation of the vehicle (10a; 10b; 10c; 10d), it is determined whether a cleaning program for cleaning the driving assistance sensor (20a; 20b; 20c; 20d) is currently active.-

摘要： Provided herein is a system and method for a sensor housing that mitigates glare within the field-of-view and facilitates cleaning of a sensor lens. A sensor assembly may include: a sensor having a sensor lens and a field-of-view through the sensor lens; and a baffle defining a sensor lens aperture, where the field-of-view through the sensor lens is through the sensor lens aperture, where the baffle includes a series of concentric rings extending away from the sensor lens aperture and increasing in diameter as a distance from the sensor lens aperture increases. According to some embodiments, the series of concentric rings defines a viewing angle, where the viewing angle corresponds to the field-of-view of the sensor lens.

摘要： A method for verifying the operation of a cleaning device mounted on a motor vehicle, comprising at least one of the following steps: commanding a pump to inject cleaning fluid as far as at least one valve during a determined time period, the command to activate the pump being coupled with the keeping of the valve or valves in the closed state; at least one measurement of a parameter relating to the pressure of the cleaning liquid upstream of the valve or valves using at least one pressure sensor; comparing the measured parameter relating to the pressure against a predetermined expected value; and determining an operating status of the cleaning device on the basis of the result of the comparison between the measured parameter relating to the pressure and the predetermined expected value; and generating a warning signal in the event that the cleaning device is malfunctioning.

摘要： A harsh environment sensor housing and cleaning system includes sensor enclosures with a rotationally symmetrical lens that can be cleaned in a lens washing space defined by the sensor enclosure. Each sensor enclosure includes a motor coupled to the lens to rotate the lens within the sensor enclosure, allowing a dirty portion of the lens move through the lens washing space for cleaning, and a clean portion of the lens to be placed in front of a sensor or camera within the sensor enclosure. A sensor enclosure and cleaning system incorporates a control unit, fluid control valves, a manifold, and fluid conduits to deliver wash fluid to each sensor housing. The fluid control valves have a reduced part count and can be used to control flow of liquids or gasses such as air.
