  • Patent number: 12117301
    Abstract: Disclosed are an apparatus and method for controlling a vehicle. The apparatus may include a sensor that detects a boundary of a road, storage that stores a road map, and a controller. The controller may determine start and end points of a first U-turn path based on a U-turn lane link in the road map, determine an arc path based on the start and end points, determine a second U-turn path centered on a front bumper based on the arc path, determine an offset based on a center point of the turning path and a center point of the road boundary, and determine a third U-turn path by applying the offset to the second U-turn path. Accordingly, stability of autonomous driving may be improved by accurately determining a road boundary in a U-turn area and generating a U-turn driving path in consideration of the turning radius of the vehicle.
