1. A method for determining a position of a motor vehicle, comprising: optically capturing at the vehicle an object having a known geographic position and distance information, with the distance information showing a relative distance to a first reference point having a known geographic position, matching the geographic position of the object with map data stored on a digital road map, optically recognizing the object at the vehicle and evaluating the distance information using optical character recognition, matching the first reference point with a second reference point represented by the map data of the digital road map, and determining the position of the motor vehicle when the first reference point and the second reference point correspond to the same geographic position.
