  • Method and arrangement for representing data in vehicle navigation systems
    Patent number: 6163752
    Abstract: A method and arrangement for representation of data in a navigation system includes an input unit, a data memory, a position-determining unit, an evaluating unit and a control unit to control a display. From a destination entered in the input unit and the current vehicle location determined by the position-determining unit, the evaluating unit determines a route to the destination from cartographic data stored in the data memory. The evaluating unit also selects reference points of decision and/or orientation along the route and the scale of the map section displayed in the display unit is adjusted as a function of the distance between the current vehicle position and the next point of decision and/or orientation.
