Abstract: A method is configured to generate a pre-derived ultra wide band (UWB) ranging secure key (URSK) according to the ranging result of a digital key, and a digital key authentication controller for a vehicle is configured to authenticate the URSK. The method for generating the pre-derived URSK includes steps of: determining a location of the digital key in relation to the vehicle according to a UWB ranging; determining a time of generating the pre-derived URSK according to the locations of the digital key; and generating the pre-derived URSK according to the time. The method may determine generation of the pre-derived URSK that is not interfered with the authentication of an active URSK according to the ranging result of the digital key, and may control the time of generating each pre-derived URSK according to first to third locations.

Abstract: A device for controlling a vehicle includes a communication circuit, a processor, and a memory, and the processor recognizes a trigger event for recognizing an external digital key corresponding to the vehicle, establishes wireless communication with a plurality of external terminals including the external digital key via the communication circuit using a first communication protocol, recognizes a received signal strength for each of the plurality of external terminals via the wireless communication, determines respective priorities of the plurality of external terminals based on the received signal strengths, and monitors a location of at least one of the plurality of external terminals based on the respective priorities using a second communication protocol via the communication circuit.

Abstract: An apparatus for controlling a vehicle includes a communication device that communicates with an authentication device of the vehicle, and a processor that searches for the authentication device inside the vehicle and prevents a guide message for authentication from being output when at least one authentication device found inside the vehicle.

Abstract: Provided is an image processing apparatus. When a plurality of images acquired by photographing different directions is input, a region search unit of the image processing apparatus may search for an overlapping region within the plurality of images. An outlier removal unit may remove an outlier within the retrieved overlapping region.
