A system and method for controlling automatic cruise control system is provided. More specifically, a request torque for the automatic cruise control system is calculated based on the target vehicle speed and the inclination angle of a road on which the vehicle travels, and the calculated request torque is distributed into engine torque and motor torque at a predetermined ratio. The engine and a motor are then controlled so that the engine and the motor generate torque at the predetermined ratio, and a speed difference between the traveling vehicle speed and the target vehicle speed are calculated. Additionally, a following motor torque is calculated for following the target vehicle speed based on the calculated speed difference and then is added to the distributed motor torque. The traveling vehicle speed is then controlled to the target vehicle speed based on the summed motor torque.
