Abstract

An apparatus and method for controlling a vehicle speed based on information about forward vehicles that travel in the same lane may be acquired using Vehicle to Everything (V2X) communications in a cooperative adaptive cruise control (CACC) system. The CACC system includes a communication unit receiving vehicle information from neighboring vehicles using V2V communications; an information collection unit collecting vehicle information of the neighboring vehicles and the subject vehicle using sensors; and a control unit determining a forward vehicle and a far-forward vehicle using the sensors,selecting first and second target vehicles for being followed by the subject vehicle based on the vehicle information of the forward vehicle and the far-forward vehicle and the vehicle information ofthe neighboring vehicles, and controlling the driving speed of the subject vehicle based on speed information of the first and second target vehicles.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to an apparatus and method for controlling speed in a Cooperative Adaptive Cruise Control (hereinafter referred to as "CACC") system, and more particularly, to a method for obtaining information based on V2X (vehicle-to-everything) communication. Apparatus and method for controlling vehicle speed based on information about a plurality of preceding vehicles traveling on the same lane. Background technique [0002] An adaptive cruise control (hereinafter referred to as "ACC") system is a system that operates to perform automatic driving at or below a speed set by a driver and maintain an inter-vehicle distance from a target vehicle at or above a predetermined distance. The ACC system provides a function for maintaining a sufficient vehicle distance to prevent a collision with a front target vehicle acquired by a distance and / or position measuring sensor mounted on the vehicle, or performs a cruise fu...
