Abstract
A driver assistance system that may rapidly determine cutting out of a preceding vehicle based on lane information obtained from a camera, the driver assistance system includes: a first sensor mounted on a vehicle and configured to acquire front image data; a second sensor selected from a group comprising a radar sensor and a lidar sensor, mounted on the vehicle, and configured to acquire front detection data; and a controller configured to select a preceding vehicle as a target vehicle based on the front image data and the front detection data and control a speed of the vehicle to follow the target vehicle, wherein the controller is configured to: recognize a left land and a right lane of a driving lane based on the front image data, calculate a lateral speed of the preceding vehicle based on the front detection data, when a difference between a length of the left lane and a length of the right lane is greater than or equal to a preset value and the lateral speed of the preceding vehicle is greater than or equal to a preset speed, recognize the preceding vehicle as a cut-out vehicle, and recognize a preceding vehicle of the cut-out vehicle as the target vehicle.
