阅读说明：本技术 保护车辆的光学传感器免受环境污染物影响的方法 (Method for protecting an optical sensor of a vehicle from environmental pollutants ) 是由 N·比尔哈尔斯 于 2021-05-13 设计创作，主要内容包括：本发明涉及用于保护车辆(10)的光学传感器(20)的方法,其中保护传感器(20)不受环境污染物(40)的影响,如果传感器(20)暴露于环境污染物,则环境污染物粘附在传感器(20)的光学表面(30)上,并且其中通过使用超声场对传感器(20)表面进行超声清洁而使环境污染物远离传感器(20)。超声清洁的超声场由保护装置(60)发射到空气中,以在传感器(20)的光学表面(30)周围提供保护区(50),从而避免使光学表面(30)与环境污染物(40)接触,其中如果环境污染物(40)进入保护区(50),则环境污染物(40)在空气中移动和/或破坏以远离传感器(20),并且其中保护区(50)提供传感器(20)的非接触式清洁。(The invention relates to a method for protecting an optical sensor (20) of a vehicle (10), wherein the sensor (20) is protected from environmental contaminants (40) which adhere to an optical surface (30) of the sensor (20) if the sensor (20) is exposed to the environmental contaminants, and wherein the environmental contaminants are kept away from the sensor (20) by ultrasonically cleaning the surface of the sensor (20) using an ultrasonic field. An ultrasonic cleaning field is emitted into the air by a protection device (60) to provide a protection zone (50) around the optical surface (30) of the sensor (20) to avoid contacting the optical surface (30) with environmental contaminants (40), wherein the environmental contaminants (40) move and/or break in the air away from the sensor (20) if the environmental contaminants (40) enter the protection zone (50), and wherein the protection zone (50) provides a non-contact cleaning of the sensor (20).)
