Publication number: 20240034279Abstract: An AV sensor can be cleaned by charging a conductive layer over a sensor surface. The conductive layer may be positively or negatively charged and can repel contaminants having the same polarity away from the sensor. The charging of the conductive layer can be triggered by a determination that the sensor needs cleaning, which can be based on sensor data captured by the sensor or a different sensor. The charging of the conductive layer may include one or more charging cycles, each of which includes charging the conductive layer with two opposing polarities. Another conductive layer may be over the conductive layer. The other conductive layer can be charged with an opposite polarity from the conductive layer so that an electric field is present between the two conductive layers. A piezoelectric layer between the two conductive layers can vibrate under the electric field. The vibration can enhance the cleaning.Type: ApplicationFiled: July 29, 2022Publication date: February 1, 2024Applicant: GM Cruise Holdings LLCInventors: Hongen Tu, Wesley Newhouse, Brian Gilbert, Devin Cass, Jason Seitz
