Vision sensing systems and methods that mitigate flicker and associated artifacts. The system includes a camera module that controls operation of a camera onboard a mobile platform and generates camera data therefrom, wherein the camera data comprises a sequential plurality of frames An exposure lock module is configured to: communicate with the camera module to receive the camera data; analyze the camera data to identify a blackout; utilize machine learning to quantify a frequency of blackouts in the camera data; generate a vision sensor command for anticipating future blackouts as a function of the frequency of blackouts; and supply the vision sensor command to the camera module. An enhanced exposure control module utilizes the vision sensor command to mitigate flicker and associated artifacts, thereby providing image stabilized enhanced frames.

The disclosure relates to detecting and clearing debris from a sensor window. For instance, a system may include the sensor window and one or more processors. The sensor window may include a transparent thin film conductor. The one or more processors may be configured to identify a change in capacitance using the transparent thin film conductor, detect debris on the sensor window using the change in capacitance, and activate a cleaning system in order to clear the detected debris from the sensor window.

This technology relates to system for clearing a sensor cover. The system may include a sprayer, a support, and a positioning device. The sprayer may be mounted to the support and direct a flow of fluid to the sensor cover. The positioning device may be configured to adjust the position of the sprayer on the support. The system may include a nozzle and the nozzle may be positioned to direct the flow of fluid to an area of the sensor cover. The system may include additional sprayers.

The disclosure relates to a method for assisting a user of a first motor vehicle in the operation of the first motor vehicle, which is located in a geographic region. A motor-vehicle-external data server device (16) divides the geographic region into a plurality of geographic sectors. A sensor device of a second motor vehicle, which is also located in the region, detects at least one measurement value, and a control device of the second motor vehicle transmits a sensor signal describing the measurement value to the motor-vehicle-external data server device. The motor-vehicle-external data server device receives a request signal from the first motor vehicle, which, at the time at which the request signal is transmitted, is not prepared to detect a measurement value of the same type. If the motor-vehicle-external data service device determines that the motor vehicles are located within the same geographic sector, the motor-vehicle-external data service device transmits the sensor signal to the first motor vehicle.

An imaging device images rearward of a vehicle through a windshield from inside a cabin of the vehicle, and a vehicle washing device includes a wiping device and a controller. The wiping device is capable of reciprocatingly wiping a predetermined range of the windshield. The predetermined range of the windshield includes an imaging range for the imaging device. The controller switches operation of the wiping device to one of a first mode or a second mode in accordance with an input. In the first mode, the wiping device wipes the predetermined range of the windshield. In the second mode, the wiping device wipes the imaging range of the windshield preferentially compared to the first mode.
