1. A method for controlling the steering of a vehicle during a parking maneuver, said method comprising: measuring a parking spot selected for parking the vehicle; generating an orientation field, which determines a number of position points within the selected parking spot and in the environment of the selected parking spot and assigns a target orientation to each position point; determining a position and orientation of the vehicle to be parked relative to the position points of the orientation field; and controlling a steering angle of the vehicle in such a way that the orientation of the vehicle at a position point assumes essentially the target orientation assigned to this position point in the orientation field, wherein as soon as it is recognized that there is a risk of collision with an obstacle if the target orientations of the orientation fields are followed, the vehicle is driven along an orientation leading around the obstacle until there is no longer a risk of collision.
