1. A method of controlling automatic cruise system which automatically controls a traveling vehicle speed of a hybrid vehicle to a predetermined target vehicle speed, the method comprising:
calculating, by a controller, request torque for the automatic cruise control system based on the target vehicle speed and the inclination angle of a road on which the vehicle is traveling; distributing, by a controller, the calculated request torque into engine torque and motor torque at a predetermined ratio and then controlling engine and a motor so that the engine and the motor generate torque at the predetermined ratio; calculating, by a controller, a speed difference between the traveling vehicle speed and the target vehicle speed; calculating, by a controller, a following motor torque that follows the target vehicle speed based on the calculated speed difference and then adding the following motor torque to the distributed motor torque; and controlling, by a controller, the traveling vehicle speed to the target vehicle speed by controlling the motor based on the summed motor torque. |
