Problems solved by technology

[0007] Since the conventional CACC system sets the immediately preceding vehicle as the target vehicle and then adjusts the speed of the host vehicle based on the determined speed of the target vehicle, there may be a problem in that sudden acceleration or sudden start often occurs
That is, in the case where the first vehicle in front is following the second vehicle in front, and the second vehicle in front is following the host vehicle, since the conventional CACC system adjusts the speed of the host vehicle by considering only the speed of the second vehicle in front, it is different from Compared with the case where the speed of the host vehicle is adjusted by considering the speeds of both the first vehicle in front and the second vehicle in front, there may be a problem in that sudden acceleration or sudden start often occurs

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0092204 filed with the Korean Intellectual Property Office on Jun. 29, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure generally relates to an apparatus and method for controlling the speed of a Coordinated Adaptive Cruise Control (CACC) system, and more particularly, to a vehicle-to-external (V2X) communication and radar-based CACC system. A technique of collecting information about a preceding vehicle traveling in the same lane (such as route information) and controlling the speed of the vehicle (such as acceleration and deceleration) using the collected information. Background technique [0004] The Smart Cruise Control (SCC) system is a system for maintaining a constant distance from the vehicle ahead. The SCC system provides a cruise functio...
