An assembly includes an inlet tube. The assembly includes a first outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The solenoid assembly has a strain gage fixed to the spring. A strain detected by the strain gage indicates whether the plunger is at the closed position.

This technology relates to a system for preventing particle buildup on a sensor housing. The system may include a sensor housing including a first surface, a motor, and a spoiler edge.

The sensor cleaning device includes a wiper configured to move over a surface of a sensor to remove foreign materials from the surface of the sensor; and a movement unit connected to the wiper and comprising at least a linkage system configured to perform folding and unfolding movements, which causes the wiper to reciprocate over the surface of the sensor.

The invention relates to a device (120) for cleaning a large-optical-surface detection module (110) of a driving assistance system (100) of a motor vehicle (300), comprising at least two rails (121a, 121b, 121c) for spraying a cleaning fluid that are arranged around the large-optical-surface detection module (110), each spray rail (121a, 121b, 121c) being configured to clean a part of the optical surface of the detection module, each spray rail being able to be activated independently of the other spray rails (121a, 121b, 121c).

The disclosure provides for a wiper system for cleaning a surface of a sensor housing, such as a sensor housing positioned on top of a vehicle. The wiper system includes a plurality of windows spaced around a sensor housing, and a plurality of wipers positioned around the sensor housing, each of the wipers includes a wiper blade configured to clean a corresponding window of the plurality of windows. The wiper system further includes a drive system including a moveable part coupled to a motor. The motor is configured to drive the drive system to simultaneously rotate the plurality of wipers around the sensor housing such that the plurality of wipers remove debris from the plurality of windows.

A sensor assembly for a vehicle includes a base, a sensor body mounted to the base and rotatable relative to the base around an axis in a direction of rotation, and a cover. The sensor body includes a sensor window and a wall having heat fins elongated circumferentially relative to the axis. The cover is positioned to cover the heat fins. The cover includes an inlet open in the direction of rotation. The cover defines an airflow path from the inlet through the heat fins. The cover includes an outlet positioned to direction air across the sensor window.

A vehicle which contributes to safe autonomous driving by washing the sensor provided in the vehicle by efficiently using a limited capacity washing solution, and a control method thereof. The vehicle includes: a first sensor; a second sensor; a driving device including at least one motor and configured to operate to clean the first sensor and the second sensor; and a controller configured to control the driving device to first wash the first sensor prior to the second sensor based on predetermined rank information when is the controller determines that at least one of the first sensor and the second sensor is contaminated.

A detection device is equipped with a system to deliver pressurized fluid or compressed air or both to a lens or other optical surface to prevent or mitigate damage caused by the impact of debris. The detection device uses its own image detection function to track the trajectory of an object that might strike and impact the detection device. The detection device activates a burst of pressurized fluid or compressed air or both to shield or mitigate damage from impact. The detection device includes a housing, at least one surface mounted to the housing, and a spray device mounted to the housing. A medium, such as a liquid, gas, or compressed air, is selectively sprayed by the spray device. The spray device is activated to spray the medium when an object is approaching the surface, such that the trajectory of the object is altered when the object contacts the medium.

Data about operating parameters external to a vehicle can be input to a neural network that outputs at least one profile defining at least one of a cleaning protocol or a cooling protocol for a vehicle sensor, wherein the operating parameters include one or more of current weather conditions, future weather conditions, images indicative of a current weather condition, city infrastructure, duration of a route to be traversed, a time period to traverse the route, and vehicle location. Operation of at least one of a cleaning device or a cooling device can be initiated according to the at least one of the cleaning protocol or the cooling protocol when the operating parameters to the at least one profile.
