The present invention relates to a cooperative adaptive cruise control (CACC) system that acquires a driving pattern of a target vehicle and variably provides an inter-vehicle distance and a responsible speed level of a subject vehicle that are followed by the CACC system based on the driving pattern. The CACC system includes a communication unit configured to receive vehicle information including positions of neighboring vehicles and driving information and road information of a region in which the subject vehicle travels using V2V (Vehicle to Vehicle) and V2I (Vehicle to Infrastructure) communications; an information collection unit configured to collect driving information of a forward vehicle, vehicle information of the subject vehicle, and the road information of the region in which the subject vehicle travels using sensors provided on the subject vehicle; and a control unit configured to select a target vehicle to be followed by the subject vehicle based on the vehicle information of the neighboring vehicles that is acquired by the communication unit and the driving information of the forward vehicle that is collected by the information collection unit, to generate a plural pieces of case information using the road information collected by the communication unit and the information collection unit, to generate control information for the generated plural cases using driving information of the target vehicle and the vehicle information of the subject vehicle, and to control an inter-vehicle distance and a responsible speed level of the subject vehicle in the CACC system based on a driving pattern of the target vehicle according to the generated control information. The CACC system according to the present invention can improve the convenience of use for a driver by simplifying a driver setting menu, and can improve the autonomous running safety of the CACC system.

    본 발명은 목표차량의 운전패턴을 파악하고, 이를 바탕으로 CACC 시스템이 추종하는 차간거리 및 응답성을 가변적으로 제공하는 CACC 시스템에 관한 것으로, V2V(Vehicle to Vehicle) 및 V2I(Vehicle to Infrastructure) 통신을 이용하여 주변차량의 위치 및 주행정보를 포함하는 차량정보 및 상기 자차량이 주행중인 지역의 도로정보를 수신하는 통신부, 자차량에 구비된 센서들을 이용하여 선행차량의 주행정보, 상기 자차량의 차량정보, 및 상기 자차량이 주행 중인 지역의 도로정보를 수집하는 정보수집부, 및 상기 통신부에서 획득한 주변차량들의 차량정보 및 상기 정보수집부에서 수집한 선행차량의 주행정보를 바탕으로 상기 자차량이 추종하기 위한 목표차량을 선정하고, 상기 통신부 및 상기 정보수집부에서 수집한 상기 도로 정보를 이용하여 복수의 케이스 정보를 생성하고, 상기 목표차량의 주행정보, 상기 자차량의 차량정보를 이용하여 상기 생성된 복수의 케이스 각각에 대한 제어정보를 생성하고, 상기 생성된 제어정보에 따라 상기 목표차량의 운전패턴에 기초하여, 차간거리 및 CACC 시스템의 응답성을 제어하는 제어부를 포함할 수 있다. 본 발명에 따른 CACC 시스템은 운전자 설정 메뉴를 간소화하여, 운전자 사용 편의성을 향상시킬 수 있고, CACC 시스템의 자동 주행 안전성을 도모할 수 있는 효과가 있다.
