Vehicle navigation system and route guidance method

摘要

A vehicle navigation system includes a road-between-guidance-target-points configuration determining unit ( 9 ) for determining a configuration of a road between two successive guidance target points whose information is extracted from information stored in a guidance target point storing unit ( 8 ). A continuous guidance threshold distance setting unit ( 10 ) sets a threshold distance for continuous guidance based on the road configuration by using a table or the like. A distance-between-guidance-target-points calculating unit ( 11 ) calculates a distance between the two successive guidance target points. When the calculated distance between the two successive guidance target points is shorter than the set threshold distance for continuous guidance, a route guidance unit ( 12 ) provides continuous guidance for users through a guidance unit ( 16 ).
