Method and apparatus for transmitting navigation information from a central data station to a vehicle-based navigation system

摘要

In a method for transmitting navigation information from a central data (5) to a vehicle-based navigation system (2), together with the optimal route (10a) from the actual position (a) of the vehicle (1) to a predetermined target (b) different alternative routes (10b, 10c, 10d) is calculated and the navigation system (2) transmits. In the case of the occurrence of an unexpected obstacle or in the case of a deviation from the preset route (10a) can be used immediately to an alternate route. The selection of the alternative routes is carried out according to the probabilities with which these routes for use are. These depend, for example according to the probability that particular sections of road the optimal route are disturbed.
