Abstract: Disclosed herein are an apparatus and a method for providing road guidance information to a vehicle. The apparatus may include: a position measurer configured to measure a position of the vehicle; a communicator configured to receive event information from an outside of the vehicle; and a processor configured to perform guidance and a warning for an event depending on whether or not the vehicle is scheduled to pass through an event occurrence point using a travel route history recorded by the position measurer and the received event information, when absence of map data is confirmed on the basis of the event information.

Abstract: The present inventive concept relates to a method for implementing surround sound system using a plurality of vehicles, which implements the surround sound by outputting a sound source corresponding to a surround sound node of itself according to a synchronization signal after each vehicle located in a local area (AVN system: Audio, Video, Navigation system) identifies the surround sound node of itself based on its position.

Abstract: The present disclosure provides an apparatus and method for controlling a cooperative adaptive cruise control (CACC) system capable of reducing a width of deceleration and acceleration to improve fuel efficiency by collecting information on preceding vehicles which are being driven on the same lane and using the collected information to control speed of a vehicle, in the CACC system on the basis of vehicle to everything (V2X) communication and radar.

Abstract: A method for issuing a certificate signing request (CSR) certificate in a vehicle-to-anything (V2X) communication environment includes: receiving, at a first server, a certificate issuance request message including vehicle identification information transmitted from a communication module of the vehicle; determining, by a second server, whether a CSR certificate corresponding to the vehicle identification information has already been issued with reference to a database; and determining, by the second server, whether to issue the corresponding CSR certificate or whether to generate an error message, based on the determination of whether the corresponding CSR certificate has already been issued.

Abstract: The present disclosure relates to an apparatus and a method for avoiding a collision including: a communication module receiving location information from another vehicle; a sensor module obtaining a location of a user's vehicle; and a control module checking a central node of an intersection that exists in a road on which the user's vehicle and the other vehicle drive, determining whether a collision between the user's vehicle and the other vehicle at the intersection is possible, based on pre-stored map data and locations of the user's vehicle and the other vehicle, and outputting an alarm when it is determined that the collision is possible.

Abstract: An on-board unit of a vehicle communication system includes: a reception module receiving a message including driving information of a nearby vehicle from the nearby vehicle; and a misbehaving vehicle detection module analyzing the received message and detecting a misbehaving vehicle based on the analyzed message.

Abstract: A method for issuing a reliable certificate to a vehicle for a vehicle-to-anything (V2X) communication in a server on a network comprises receiving a certificate issue request including vehicle identification information and road-side unit (RSU) identification information from an RSU. Log information for the certificate issue request is extracted from a database. Normality or abnormality is determined according to whether a predetermined certificate issue criteria is satisfied by analyzing the certificate issue request and the log information. The certificate is issued and the certificate is transmitted to a vehicle communication module according to determination of normality, or certificate revocation information is registered according to determination of abnormality.

Abstract: A method for transmitting traffic information includes detecting an occurrence event by a first vehicle terminal; generating a traffic information message including information for the occurrence event by the first vehicle terminal; transmitting the traffic information message through vehicle to vehicle (V2V) communication by the first vehicle terminal; receiving and analyzing the traffic information message by the second vehicle terminal which drives in an opposite direction as compared to the first vehicle terminal; retransmitting the traffic information message to a third vehicle terminal located behind the first vehicle terminal depending on an analysis result of the traffic information message by the second vehicle terminal; and outputting an alert based on the event occurrence information of the traffic information message transmitted from the second vehicle terminal to the third vehicle terminal.
