The invention is concerned with a method for protecting an optical sensor (20) of a vehicle (10), wherein the sensor (20) is protected from environmental pollutants (40) which adhere to an optical surface (30) of the sensor (20) if the sensor (20) is exposed to them, and wherein the environmental pollutants are kept away from the sensor (20) by an ultrasonic cleaning of the sensor (20) surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device (60) into the air to provide a protection zone (50) around the optical surface (30) of the sensor (20) such that a contact of the optical surface (30) with the environmental pollutants (40) is avoided, wherein the environmental pollutants (40) are moved and/or destroyed in the air away from the sensor (20) if they enter the protection zone (50), and wherein the protection zone (50) provides a contactless cleaning of the sensor (20).
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。
