<p>The method involves implementing navigation of a vehicle in dependent upon stored navigation data (1), which comprises confidence levels (V, V1-Vn) that indicate confidence of correctness of the navigation data. The navigation data includes data objects (D) e.g. roads, which comprise attributes. A geographical position of the vehicle is determined, and an actual surrounding area of the vehicle is monitored. An actual attribute of the surrounding area is determined, and the geographical position is compared with the objects for identifying actual data objects. The attributes are selected from a group that includes a land attribute (D1), region attribute (D2), location attribute (D3), geographical data attribute (D4), map mistake attribute (D5), road name attribute (D6), road class attribute (D7), recording type attribute (D8), data source attribute (D9) and recording data attribute (D10). Independent claims are also included for the following: (1) a navigation system for a vehicle (2) a computer program with program code units for implementation of a navigation method.</p> |
