Problems solved by technology

However, by only transmitting signal information, an automated driving system may not be able to detect information about which lane the host vehicle is traveling from to which lane
Further, since the signal information input through the V2X communication device uses the truth value (GroundTruth, GT) without separate verification, if an error occurs in the signal information, a major accident may occur at the intersection

Abstract

The invention provides an autonomous driving method of a vehicle using V2X communication. The method includes acquiring signal information about a plurality of traffic lights installed at an intersection, determining a signal error in at least one of the plurality of traffic lights by comparing signal information about at least two traffic lights intersecting or facing each other among the acquired signal information, and resetting a driving path of a host vehicle depending on a result of the determination.

Description

technical field [0001] The present invention relates to a vehicle automatic driving system and method using V2X communication. Background technique [0002] In order to pass through pedestrian crossings or intersections with traffic lights, conventional automatic driving systems mainly use cameras to recognize traffic lights and then determine whether to continue driving. However, if only the camera is used to recognize the signal, although the recognition performance of the camera is good, it may fail to detect when the traffic light is blocked by the vehicle in front of the host vehicle or when the corresponding traffic light cannot be seen due to the position of the host vehicle The signal state of a traffic light, or possibly mistaking the signal state of a traffic light for another signal. [0003] In another method, a V2X communication device installed on a traffic signal may transmit signal information to a host vehicle. However, the automated driving system may not...
