The present invention relates to a method for improving fuel efficiency in a cruise operation using a system cooperation and a cruise control system. In accordance with the present invention, the method for improving fuel efficiency in a cruise operation using the system cooperation applied to the cruise control system (10) is able to, when an engine control unit (300) detects a cruise resume request of a vehicle (1), in case of a neutral control coasting driving, control a brake (700), reduce the vehicle speed, and control the cruise torque of an engine (200) by engaging a clutch, or in the case of start stop control (SSC) driving, control the brake (700), reduce the vehicle speed, drive the engine (200), and control the cruise torque of the engine by engaging the clutch. Accordingly, the present invention is able to, for a direct request for reducing speed of a driver who has no will to accelerate, reduce the wasted power in the NCC driving, reduce an unnecessary engine driving process in the SSC driving, and improve fuel efficiency.

    본 발명의 크루즈 컨트롤 시스템(10)에 적용된 시스템 협조를 이용한 크루즈동작 연비개선제어 방법은 엔진 제어기(Engine Control Unit)(300)가 차량(1)의 크루즈 Resume 요청 검출 시 NCC(Neutral Control Coasting) 주행인 경우 브레이크(700)의 제어로 차속을 감속한 상태에서 클러치 체결로 엔진(200)의 크루즈 토크를 제어하거나 또는 SSC(Start Stop Control) 주행인 경우 브레이크(700)의 제어로 차속을 감속한 후 엔진(200)을 구동한 상태에서 클러치 체결로 엔진(200)의 크루즈 토크를 제어함으로써 가속 의지가 없는 운전자의 직접적인 감속 요청에 대해 NCC에서 동력 낭비를 줄이면서 SSC에서 불필요한 엔진 구동을 줄여 연비가 개선되는 특징이 구현된다.
