Various embodiments relate to sensing defects associated with a window. Furthermore, various embodiments relate to performing image processing to produce a corrected image of a scene based at least partly on data corresponding to the detected defects. In some examples, one or more lighting modules may be used to illuminate the window to facilitate detection of the defects by one or more sensor devices.

The vehicle control apparatus is mounted on a vehicle. The vehicle control apparatus includes a cleaning unit capable of performing a first cleaning operation to clean a detecting surface part of a LiDAR using cleaning fluid, and a cleaning control ECU configured to execute a first light-degree cleaning process to let the first cleaning unit perform a first cleaning operation for a first light-degree cleaning time. The cleaning control ECU executes the first light-degree cleaning process when a first light-degree cleaning condition becomes satisfied within a first allowable period.

According to one aspect, a vehicle includes a chassis, a propulsion system carried on the chassis, a control system carried on the chassis, and a components arrangement carried on the chassis. The propulsion system configured to propel the vehicle, and the control system is configured to enable the vehicle to operate autonomously. The components arrangement includes at least a frame, a panel having a surface, a wiper arrangement having at least one wiper, and a fluid distribution arrangement. The frame is configured to interface with the chassis and to support the panel, the wiper arrangement, and the fluid distribution arrangement. The fluid distribution arrangement is configured to dispense a fluid onto the surface and the wiper is configured to sweep over the surface.

The invention relates to a method for automated cleaning of an optical surface of a motor vehicle, comprising at least one cycle of cleaning (38) the optical surface which comprises a plurality of separate and successive steps of spraying fluid, said cycle of cleaning (38) comprising at least a first step of spraying (30) cleaning fluid onto the optical surface, a second step of spraying (32) cleaning fluid onto the optical surface, and a break step (34), of non-zero duration, between the first step of spraying (30) cleaning fluid and the second step (32) of spraying cleaning fluid.

A device is described for protecting a sensor window. The device includes a two-piece nozzle system and is configured for generating a first and a second fluid flow, a first piece of the two-piece nozzle system being fixedly situated with respect to the sensor window, and a second piece of the two-piece nozzle system being configured for assuming different positions with respect to the first piece of the two-piece nozzle system, and the two-piece nozzle system being aligned with respect to the sensor window to direct a predominant portion of the first fluid flow in parallel to the sensor window and to direct a predominant portion of the second fluid flow in the direction onto the sensor window.

Upon determining an autonomous mode for a vehicle is activated, a motor is actuated to move a wiper across a windshield in a low mode based on determining to clean the windshield. A blower is actuated to direct air across a sensor. Then, after expiration of a first timer, a pump is actuated according to a pressure threshold to direct fluid through a fluid nozzle and across the windshield towards the sensor. The pressure threshold specifies a fluid pressure less than a maximum fluid pressure for the pump. The pump is stopped after expiration of a second timer.

Systems and methods are directed to obtaining autonomous vehicle sensor data of an autonomous vehicle. In these system and methods that include determining a direction of motion of a vehicle based on a predicted navigational position of the vehicle, determining, based at least in part on the predicted navigational position, a change in a future light positional information that may be received by one or more sensors compared to a current light positional information being received by the one or more sensors and cleaning the one or more sensors of the vehicle prior to the change in the future light positional information and prior to the vehicle reaching the predicted navigational position.

An outside viewing device for a vehicle, having a camera that is housed in a casing having a frontal wall through which there passes an imaging window, and an internal partition which is parallel to the frontal wall and through which there passes an opening next to the imaging window. In addition, two peripheral wiper seals, disposed at the periphery of the window and the opening, delimit a guide in which a transparent screen slides, in a sealed manner, between at least two imaging positions, in each of which different surface portions of the screen are positioned next to the imaging window. Finally, a device for moving the screen is designed to slide the latter between its different positions.

A device which is designed to detect surroundings and which includes a housing and a sensor situated within the housing. The housing includes a transmitter/receiver window, through which the corresponding sensor signals may be emitted into the surroundings by the sensor, and/or sensor signals from the surroundings may be received. The device includes a cover, the cover being designed to be transparent to the sensor signals, and the cover being designed to cover the transmitter/receiver window against exterior surroundings of the device. The device includes a cleaning unit, which is situated at an outside of the housing and is movable relative to the housing using a drive unit. The cleaning unit is designed to remove contaminants from the cover. The cleaning unit includes at least one first nozzle to spray a cleaning liquid onto the cover, and at least one second nozzle to blow a gas onto the cover.

Systems and methods for cleaning transmission surfaces for optical and sensor surfaces in order to maintain optimal performance under a variety of weather and environmental conditions using synthetic jet actuators. The actuators can emit a jet of water or air depending on environmental conditions and the waveform, frequency, amplitude of the actuator can be adjusted based on particle characteristics and transmission signal quality in order to better clean the surfaces.
