Abstract
A control system for a vehicle which has a first controller for storing navigation map data and a separate second controller for storing update data. The navigation map data are updated outside of the first controller. The first controller or at least the navigation system is designed to perform map matching and to ascertain a possible location area for the vehicle on the basis of an evaluation of a travel history for a travel angle, or other measurement data which characterize the movement or the location of the vehicle.
