1. A method for determining a position of a vehicle, comprising:
determining highly accurate localization data for positions of the vehicle when traveling along a route, wherein the highly accurate localization data are determined using a digital area map and a sensory detection of landmarks marked on the digital area map;
capturing odometric measured variables for an own odometry of the vehicle when traveling along the route;
jointly evaluating the determined highly accurate localization data and the captured odometric measured variables;
determining, if accurate localization data can be determined at the current position of the vehicle;
selectively correcting the own odometry of the vehicle based on the evaluation based on the joint evaluation of the determined highly accurate localization data and the capture odometric measured variables,
if accurate localization data can be determined; and
selectively correcting the own odometry of the vehicle based on the last corrected own odometry in case the vehicle is travelling in an area in which highly accurate localization data cannot be determined.
