Claim 11:
12. A method for determining an angle between a vehicle and a trailer connected to the vehicle, having the following steps:
sensing the trailer by a sensing unit including a camera which is arranged outside of a center of the vehicle toward the trailer;
determining, by an evaluation unit having a first input connected to an output of the camera and a second input connected to an output of a computer-readable medium on which a program is stored, a distance between the sensing unit and the center of the vehicle by an evaluation unit;
sensing, by the evaluation unit, symmetrical feature pairs of the trailer with respect to a longitudinal axis of symmetry of the trailer;
determining, by the evaluation unit, a distance between the vehicle and the trailer if the longitudinal axis of symmetry of the trailer and the center of the vehicle are in a line; and
determining, by the evaluation unit, the angle between the vehicle and the trailer on the basis of the symmetrical feature pairs of the trailer and the determined distance between the sensing unit and the center of the vehicle for use by a driver assistance system of the vehicle,
wherein the sensing unit senses image data of the trailer, and the evaluation unit is configured by the program to determine the distance between the trailer and the vehicle on the basis of the distance between the sensing unit and the center of the vehicle and the positions of the sensed symmetrical feature pairs of the trailer in the image data.
