Guidance system and setting up method and program of same

Abstract

A program for a navigation system and a setting method of the navigation system, comprising an information acquisition and processing device (91) for acquiring map data and an entrance / exit interchange hub, a display unit (35), and displaying information based on the above-mentioned map on the display unit (35). A setting screen display processing device (93) including a map of an entrance and exit interchange hub and a simple route map of an adjacent interchange hub formed from the data. When the map is scrolled, the simple route map is updated correspondingly to the map, which can simplify the operation of setting the entrance and exit interchange hubs.

Description

technical field [0001] The present invention relates to a program of a navigation system and a setting method of the navigation system. Background technique [0002] In prior art navigation devices, for example, the current position of the vehicle is detected by GPS (Global Position System), that is, the current position, and at the same time, the orientation of the vehicle, that is, the self-position, is detected based on the rotational angular velocity of the vehicle detected by the gyro sensor, that is, the rotation angle. For the direction of the vehicle (own vehicle), the present position, the direction of the own vehicle and the surrounding map are displayed on the set map screen on the monitor of the display unit. Therefore, an operator, such as a driver, can drive the vehicle based on the present position and the direction of the vehicle displayed on the above-mentioned map screen. [0003] In addition, the driver can set the destination location. After setting the ...

Problems solved by technology

[0011] However, in the navigation device of the above-mentioned prior art, on the above-mentioned entrance and exit interchange hub setting screen, since only the searched entrance and exit interchange hub is displayed as a default value, the adjacent to the entrance and exit interchange hub is displayed as a default value. For interchange hubs, the driver cannot grasp the overall situation of the path, and it is very difficult to judge the positional relationship between the starting position, the destination position, and the entrance and exit interchange hubs, and it is impossible to set an appropriate entrance and exit interchange hub corresponding to the departure position and destination position
