Position correction of a vehicle by referencing to objects in the surroundings

A system for correcting a position of a vehicle with a global satellite navigation system (GNSS) for determining the actual position comprising:

• a first position of the vehicle determined with the GNSS;
• a digital map and a computing unit, wherein the computing unit determines a second position of the vehicle by adjusting the first position into a road in the digital map;
• a device for identifying at least one object in the surroundings of the vehicle, the position of which can be referenced in the digital map;
• at least one sensor for determining a real distance between the vehicle and the respective object;
• wherein the computing unit is further designed for the calculation of a computed distance between the second position and the respective object;
• and
• wherein a corrected position of the vehicle can be determined by minimizing the deviation of the computed distance from the real distance.
