The present disclosure provides a sensor assembly with a cleaning function. A system includes a sensor window, a sensor having a field of view through the sensor window, a piezoelectric vibrator positioned to apply vibration to the sensor window, and a computer communicatively coupled to the sensor and the piezoelectric vibrator. The computer is programmed to identify a type of obstacle of the sensor window based on data from the sensor and instruct the piezoelectric vibrator to vibrate the sensor window with vibration having a vibration profile. The vibration profile has at least one of a frequency or a phase velocity selected according to the identified obstacle type.
本公开提供了“具有清洁功能的传感器组件”。一种系统包括传感器窗口、具有穿过所述传感器窗口的视场的传感器、定位成向所述传感器窗口施加振动的压电振动器以及通信地联接至所述传感器和所述压电振动器的计算机。所述计算机被编程为基于来自所述传感器的数据来识别所述传感器窗口的障碍物的类型,并指示所述压电振动器以具有一定振动曲线的振动来使所述传感器窗口振动。所述振动曲线具有根据所识别的障碍物类型选择的频率或相速度中的至少一个。
