본 발명은 선행차량 존재시 적응형 순항 제어 시스템 연비 향상 제어방법에 관한 것으로, 순항 제어 시스템을 이용하고 있는 차량에서 선행차량이 탐지된 경우, 선행차량의 속도, 상기 차량의 현재속도, 차량에 설정된 최저주행 속도 및 감속거리를 고려하여 주행 차량이 최적의 비용을 이용하여 주행을 수행하도록 설정되는바, 설정된 주행방법을 추정하도록 차량속도를 제어하여 연비를 향상시키는 선행차량 존재시 적응형 순항 제어 시스템 연비 향상 제어방법을 제공한다.
A control method for improving fuel efficiency in an adaptive cruise control system includes: setting a target velocity profile based on a current velocity and position when a vehicle is driven by the adaptive cruise control system; determining, by the controller, whether the preceding vehicle exists while driving by the target velocity profile; comparing, by the controller, a minimum distance for preventing a collision between the preceding vehicle and the following vehicle in a case of applying the target velocity profile with a first distance between the preceding vehicle and the following vehicle when the preceding vehicle exists; and performing, by the controller, fuel efficiency driving of the following vehicle when the minimum distance is larger than the first distance and performing driving of the following vehicle according to the target velocity profile when the minimum distance is smaller than the first distance.
