Description

Vehicle Radar Cover and Operating Method for the Same The present invention relates to a radar cover and a method of operation thereof, and more specifically, to a radar cover including a heating function for snow removal and defrosting on a vehicle radar and a method of operation thereof. Recently, research and development of automotive radar has been underway. For example, vehicle radar can be utilized in technologies such as Forward Collision Warning, Rear Cross-Traffic Collision-Avoidance Assist, Lane Departure Warning systems, Advanced Emergency Braking System, and Adaptive Cruise Control. In particular, vehicle radars can be divided into front radars and rear-side radars. Front radars can be sensors designed to assist the driver, while rear-side radars can be sensors designed to ensure the driver's safety. Conventional vehicle radar sensor modules are covered with protective covers to mitigate external impacts. However, due to the driving environment, mist caused by moisture, snow, ice, or frost can accumulate on these covers, potentially leading to performance degradation of the radar sensor modules. Consequently, there is a need for vehicle radar covers designed to address this issue. FIG. 1 is a drawing illustrating a vehicle radar cover according to an embodiment of the present invention positioned at the front of a vehicle. FIG. 2 is a perspective view of a vehicle radar cover according to an embodiment of the present invention. FIG. 3 is an exploded perspective view of a vehicle radar cover according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a vehicle radar cover according to an embodiment of the present invention. FIG. 5 is an example of a heating wire (110) of a heating film (100) according to an embodiment of the present invention. FIG. 6 is a flowchart of the operation method of a vehicle radar cover according to an embodiment of the present invention. FIG. 7 is a detailed flowchart of the operation method of a vehicle radar cover according to an embodiment of the present invention.
