  • Method and apparatus for enhancing vehicle navigation through recognition of geographical region types
    Patent number: 5731978
    Abstract: A method for navigating with a vehicle navigation system using recognition of geographical region types in a map database. The system's map database stores information representative of a plurality of geographical region types. A geographical region type of a geographical region in which the navigation algorithm is operating is determined. At least one parameter related to the navigation algorithm is then set to correspond to the geographical region type. Navigation is performed using the navigation algorithm. Throughout the operation of the navigation algorithm, the system repeatedly determines whether the geographical region type has changed, and if so, changes the algorithm parameter(s) to correspond to the new geographical region type.
