Patent number: 12043225Abstract: Techniques are described for cleaning sensors of a vehicle. An attribute of the surrounding environment (e.g., type of precipitation, intensity of precipitation, etc.) is determined along with orientations and/or attributes of the sensors (e.g. fields-of-view, focal lengths, spectral ranges, etc). Cleaning frequencies are then be determined based, at least in part, on the attribute of the environment together with the orientations and/or attributes of the sensors. Cleaning elements are then activated at the determined frequencies to clean the sensors. In some examples, the cleaning frequencies may be determined based additionally on an attribute of travel of the vehicle (e.g. direction of travel of the vehicle, speed of the vehicle, etc.).Type: GrantFiled: December 1, 2021Date of Patent: July 23, 2024Assignee: Zoox, Inc.Inventors: Rajith Jayaratne, Daniel Glenn Johnson, Bingchao Han, Carter William McEathron, Raghuraman Surineedi, Evan David Cook
