METHOD AND APPARATUS FOR CONTROLLING STEERING OF AN AUTONOMOUS VEHICLE FOR DRIVING BETWEEN FLOORS

An apparatus calculates a steering angle of a vehicle and includes: an obstacle-information acquisition unit configured to acquire obstacle information related to an obstacle of an inter-floor connection ramp within an area of interest of the vehicle; a safe-area-direction acquisition unit configured to acquire a front area having a predetermined width in a width direction and a length as long as a length of an area in contact with the obstacle in a longitudinal direction with respect to a center point of a front end of the vehicle, and to acquire a safe area direction vector heading from the center point of the front end towards an end of the front area; a movement-direction acquisition unit configured to determine a movement direction of the vehicle according to the safe area direction vector, the obstacle information, and driving direction information depending on a current steering angle of the vehicle; and a steering-angle calculation unit configured to calculate a target steering angle of the vehicle based on the movement direction and the current steering angle.
