Description

System and method for controlling a charging door of a vehicle based on ultra-wideband The present invention relates to vehicle control, and more specifically, to a system and method for controlling a vehicle's charging door based on Ultra Wide Band (UWB). As vehicle control technology continues to advance, user demand for charging convenience and intelligence is steadily increasing. Conventional methods for opening vehicle charging doors mainly include opening using a car key, opening using an in-vehicle button, and opening using an in-vehicle button. These conventional methods are not convenient. In particular, since the user must operate it manually in cold or rainy weather, it is not only inconvenient but may also cause inconvenience to the user. In addition, if the instructions on the charging port are unclear, users may experience difficulties when charging, and the vehicle may even be damaged due to improper operation. Therefore, the design of vehicle charging doors must evolve in a more intelligent and human-friendly direction to provide a more convenient user experience. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. Hereinafter, exemplary embodiments of the present invention will be described in more detail by combining the drawings. For clarity, the same components in different drawings are indicated by the same reference numerals. It should be noted that the drawings are illustrative only and are not necessarily drawn in proportion.
