NAVIGATION DEVICE AND METHOD FOR POSITION DETERMINATION BY MEANS OF DEAD RECKONING

The navigation device and the corresponding method for position determination utilize dead reckoning. A position is calculated by a processor on the basis of measured values from a distance sensor and a direction sensor. The measured values are compared with a probable position on a stored digital road map. The deviation between the calculated position and the corresponding position on the digitized road map can be saved. Saved deviations form the basis of a correction value with which the calculated position can be corrected.
