Document Type and Number:
WIPO Patent Application WO/2021/066211
Kind Code:
A1
Abstract:
Disclosed are a foreign matter removal device and an autonomous driving system using same. The foreign matter removal device includes: a sensor which receives radio waves from the outside; a cover which covers effective radio wave transmission and reception areas of the sensor through which the radio waves pass; a piezoelectric film which covers effective radio wave transmission and reception areas of the sensor cover; a driving unit which applies an oscillation signal to the piezoelectric film; and a control unit which controls the driving and oscillation period of the piezoelectric film by controlling the driving unit in response to at least one among a reception signal analysis result of the sensor and data received from a network. A LiDAR system and an autonomous driving system using same according to the present specification may be linked to an artificial intelligence module, an unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to a 5G service or the like.
