本文公开了用于提高CACC系统中的燃料效率的控制装置和方法，其可以通过控制车辆速度，使得如果使用CACC系统的车辆感测到前方车辆并进入CACC激活模式，则考虑到目标车辆速度、当前车辆速度、车辆中设定的最小行驶速度和减速距离使用优化成本行驶车辆来提高燃料效率。用于提高CACC系统的燃料效率的控制方法包括基于主体车辆的目标速度和预期行驶路径来设定目标速度曲线、确定是否存在主体车辆要跟随的目标车辆，以及根据是否存在目标车辆根据所设定的目标速度曲线来控制主体车辆的行驶速度。 Disclosed herein is a control apparatus and method for improving fuel efficiency in a CACC system, which can improve fuel efficiency through control of a vehicle speed so that a vehicle travels using an optimized cost in consideration of a target vehicle speed, current vehicle speed, minimum driving speed set in the vehicle, and a deceleration distance if the vehicle that uses the CACC system senses a forward vehicle and enters into a CACC active mode. The control method for improving fuel efficiency in a CACC system includes setting a target speed profile based on a target speed of the subject vehicle and an expected driving path, determining whether a target vehicle to be followed by the subject vehicle exists, and controlling the driving speed of the subject vehicle accordin
