| 摘要 |
The invention relates to a navigation device and a method for position determination by means of coupled navigation, wherein a comparison is made between a position calculated by a processor (12) on the basis of measured values provided by a distance sensor (13) and a direction sensor (14) and a probable position stored in a digital road map. The deviation between the calculated position and the corresponding position are stored in the digitized road map. The stored deviations are used to generate a correction value serving to correct the calculated position.
