Problems solved by technology

[0010] However, in the above-mentioned prior art, there is a problem that the scale of the program for realizing the navigation function is too large, resulting in a decrease in processing capacity, and it is impossible to quickly provide route information or guidance information to the user.
In addition, there are also problems in that since the program becomes complicated, it takes a lot of time to create the program, and program failures often occur

Abstract

Provided is a navigation device comprised of a map data storage unit (12) for storing flags which include only the information required for executing a navigation function created on the basis of map data, and a controller (10) which reads out the flags from the map data storage unit and uses the flags which have been read out to execute the navigation function.

Description

technical field [0001] The present invention relates to a navigation device that guides a user to a destination, and in particular relates to a technique for efficiently performing navigation functions such as route search or guidance. Background technique [0002] In a conventional navigation device, the current position of the own vehicle obtained by the own-vehicle position calculation unit is superimposed on a map and displayed on a display device. In addition, a route search is carried out in which a recommended route from the current position of the own vehicle to the destination via a passing point is searched based on the map data and displayed on the map. Further, according to the data of the road sections included in the map database, the guidance is implemented according to the recommended route obtained through the route search. [0003] Such a navigation device uses data such as road width, road class, and speed limit of each road contained in a map database wh...
