A method for controlling cruise driving of a vehicle performed by a controller is provided. The method includes determining whether a turning section is present on a road in front of the vehicle based on information of the road included in navigation information. When the turning section is present on the road, the turning section is divided into an entry area and an escape area. The entry area is an area where speed of the vehicle is adjusted from cruise driving speed to target deceleration speed and the escape area is an area where speed of the vehicle is controlled from the target deceleration speed to the cruise driving speed. When the vehicle is located in the entry area a starter-generator connected to an engine is operated to perform regenerative braking to reduce the speed of the vehicle from the cruise driving speed to the target deceleration speed.
