Embodiment approach 1

[0040] figure 1 It is a block diagram showing the configuration of the map information processing device according to Embodiment 1 of the present invention. The map information processing device includes: a navigation device 1 , a display device 40 connected to the navigation device 1 , an audio output device 41 , an input device 42 , a vehicle speed sensor 43 , an angular velocity sensor 44 and a GPS receiving antenna 45 .

[0041] Navigation device 1 comprises: display map calculation part 10, route calculation part 11, display control part 12, sound output control part 13, input receiving part 14, position measuring part 15, HDD (Hard Disk Drive, hard disk drive) 16, HDD access unit 17 , temporary storage unit 18 , new road detection unit 19 , new road generation unit 20 , road information update unit 21 , new road management unit 22 , new road editing unit 23 and central control unit 25 .

[0042] The central control unit 25 controls the display map calculation unit 10, t...

Embodiment approach 2

[0087] In the above-mentioned map information processing device according to Embodiment 1, new road information is edited by moving points on new roads, but in the map information processing device according to Embodiment 2, new road information is edited by adding new point coordinates to new roads. , or delete the location on the new road to edit the new road information.

[0088] The structure and figure 1 The configuration of the map information processing device according to Embodiment 1 shown is the same. In addition, in the map information processing device according to Embodiment 2, the method for realizing Figure 8 The block diagram shows the structure of the new road editing process. Next, point addition processing for adding a reference point and point deletion processing for deleting a reference point will be described.

Embodiment approach 3

[0105] The above-described map information processing device according to Embodiment 1 judges whether the destination of the moving point is an existing road or an intersection, but in cases such as when an elevated road and a general road exist side by side, the destination road may not be known. Which of the multiple roads should be connected to. In such a case, the map information processing device according to Embodiment 3 allows the user to confirm and select destination candidates.

[0106] The structure and figure 1 The configuration of the map information processing device according to Embodiment 1 shown is the same. In addition, in the map information processing device according to Embodiment 2, using the realization Figure 8 The structure used for the new road editing process is shown.

[0107] Next, refer to Figure 20 The shown flowchart explains the operation of the map information processing device according to the third embodiment. First, the point coordin...

Abstract

A map information processing device enabling normal map display and route guidance. When a road corresponding to a user's current position detected by position detection means (15) is not present in a map information storage section (16a), the road is defined as a new road. A new road detection section (19) creates new road travel history information representing a history of travel on the new road. A new road creation section (20) creates new road information based on the new road travel history information. A new road information storage section (16b) stores the new road information. A new road edit section (23) edits the new road information acquired from the new road information storage section (16b). A road information update section (21) adds the new road information edited by the new road editing section (23) to the map information storage section (16a).

Description

technical field [0001] The present invention relates to a map information processing device for processing map information, in particular to a technology for detecting new roads and writing map information. Background technique [0002] Conventionally, an in-vehicle navigation device is known. The map information processing device built in the navigation device displays a map on the display device based on the map information stored in advance. Since the driver can drive while confirming the position of the vehicle by looking at the map displayed on the display device, he can reach the destination reliably and quickly without getting lost. [0003] As such a navigation device, there is known a navigation device that detects a new road from the driving history when driving a road that does not exist in the map information it owns, and adds or updates the map information it has. (For example, refer to Patent Document 1). This navigation device performs processing to connect...
