Patent ID: 7440850

Claim:
A vehicle navigation system, comprising: a memory unit for storing map data; an input unit for obtaining information related to an intersection that the vehicle approaches; a GPS unit for detecting a present position of the vehicle based on information from at least one GPS satellite; a sensor unit for detecting a direction in which the vehicle is traveling; a controller for using map data from the memory unit, information related to the intersection from the input unit, information related to the present position of the vehicle from the GPS unit and direction information from the sensor unit in order to generate a map of the intersection, an indication of the vehicle's progression along a road approaching the intersection and at least one road departing the intersection and an arrow indicating a suggested route for approaching and departing the intersection; and a display unit for displaying the map of the intersection, the indication of the vehicle's progression and the arrow, wherein the controller calculates a relative angle between the road approaching the intersection and the one road departing the intersection and generates the indication of the vehicle's progression by one of gradually filling the arrow with color and gradually removing color from the arrow.
