The present invention relates to a method for protecting an optical sensor (20) of a vehicle. When the sensor (20) is exposed to environmental pollutants, the sensor (20) is protected from the environmental pollutants attached to an optical surface (30) of the sensor (20), and the environmental pollutants are kept apart from the sensor (20) by an ultrasonic cleaning process on the surface of the sensor (20) using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning process is irradiated with the air by a protector apparatus (60) for providing a protective area (50) on a circumference of the optical surface (30) of the sensor (20), thereby avoiding the contact between the optical surface (30) and the environmental pollutants (40). When the environmental pollutants enter the protective area (50), the environmental pollutants (40) are destroyed in the air and/or are moved to be apart from the sensor (20), and the protective area (50) provides a non-contact cleaning process for the sensor (20).
본 발명은 차량의 광학 센서(20)를 보호하는 방법에 관한 것으로서, 센서(20)가 환경 오염물에 노출된다면 센서(20)의 광학 표면(30)에 달라붙는 환경 오염물로부터 센서(20)가 보호되고, 초음파 필드를 이용하는 센서(20) 표면의 초음파 세정에 의해 환경 오염물은 센서(20)로부터 멀어지게 유지된다. 초음파 세정의 초음파 필드는 센서(20)의 광학 표면(30) 둘레의 보호 영역(50)을 제공하도록 보호 장치(60)에 의하여 공기로 조사됨으로써, 광학 표면(30)과 환경 오염물(40)의 접촉이 회피되는데, 환경 오염물이 보호 영역(50)에 진입하면 환경 오염물(40)은 센서(20)로부터 멀어지게 공기중에서 파괴되고 그리고/또는 움직이며, 보호 영역(50)은 센서(20)의 비접촉 세정을 제공한다.
