The present invention discloses a system and method for cleaning a sensor lens. A lens-cleaning assembly includes an ultrasonic cleaning system configured to selectively generate vibrations in a lens. The ultrasonic cleaning system is operable to selectively generate cleaning vibrations at a plurality of pulse widths. The cleaning system also includes a controller in communication with the ultrasonic cleaning system. The controller is configured to automatically determine a target pulse width among the plurality of pulse widths in response to a detected characteristic of a detected occlusion on the lens, and to automatically control the ultrasonic cleaning system to generate a cleaning vibration having the target pulse width.
本发明公开了用于清洁传感器透镜的系统和方法。一种透镜清洁组件包括超声波清洁系统,该超声波清洁系统被配置成选择性地在透镜中产生振动。超声波清洁系统能操作以选择性地产生多个脉冲宽度的清洁振动。清洁系统还包括与超声波清洁系统通信的控制器。控制器被配置为响应于在透镜上检测到的遮挡的检测特性,自动确定多个脉冲宽度中的目标脉冲宽度,并且自动控制超声波清洁系统以产生具有目标脉冲宽度的清洁振动。
