no. 1 Embodiment approach

[0046] figure 1The illustrated navigation device (NAVI APPA) 1 is mounted on a vehicle, and is composed mainly of a control device (CONT) 10 . The control device 10 is configured as a so-called computer system, and has a central processing unit (Central Processing Unit (CPU)), a read only memory (Read Only Memory (ROM)), a random access memory (Random Access Memory (RAM)), an input / Output interface (Input / Output Interface (I / O)), and the bus connecting them.

[0047] A geomagnetic sensor (GEOMAGN SENS) 11, a gyroscope (GYRO) 12, a distance sensor (DIST SENS) 13, a GPS receiver (GPS REC) 14, and a map data input unit (M-DATA IN) 15 are connected to the control device 10 , Operation switch group (SWITCH) 16, speed sensor (SPEED SENS) 17, G sensor (acceleration sensor: G-SENS) 18, external memory (EXT MEMO) 19, display device (DISPLAY) 20, sound controller (AUDI CONT ) 21, remote sensing sensor (REMOTE SENS) 22, camera (CAMERA) 23, and scanner (SCAN) 24.

no. 2 Embodiment approach

[0095] Next, according to Figure 7 and Figure 8 A navigation device 1 according to a second embodiment of the present invention will be described. In the second embodiment, the extended road setting process of the above-mentioned embodiment executed by the control device 10 is different. Therefore, according to Figure 7 and Figure 8 The extended road setting process executed by the control device 10 of this embodiment will be described. This extended road setting process is similar to the extended road setting process of the first embodiment, and is executed by the control device 10 at the timing when the IG switch is turned on. Of course, the processing execution timing is not limited to this. In addition, since there are processes added to the extended road setting process of the above-mentioned embodiment, the description will focus on these processes.

[0096]After acquiring the link in the first S200, the control device 10 acquires the road type, the road width,...

no. 3 Embodiment approach

[0111] Next, according to Figure 9 , Figure 11 to Figure 15 (b) The navigation device 1 according to the third embodiment of the present invention will be described. The navigation device 1 according to the present embodiment differs only in the switching of the map display on the display device 20 , so descriptions of the configuration and the like are omitted.

[0112] The control device 100 of the navigation control device 1 according to this embodiment includes a recognized road determination unit (RCG RD DETM) 100a, a recognized road determination unit (RCG RD SPCY) 100b, a switching unit (SW) 100c, and a notification unit (NOTIFY) 100e.

[0113] In the present embodiment, the "moving road" is a road that is actually traveled and the travel history information is set to "1", and the "extended road" is a road that extends from the travel road and the travel history information is set to "2". "Together they are called "knowing the road". In addition, the external memor...

Abstract

A navigation device is provided with a movement road identification unit (10a), a continuity determination unit (10b), and an extension road setting unit (10c). The movement road identification unit identifies the movement road that was actually travelled by a vehicle by acquiring the current location of the vehicle. The continuity determination unit determines whether there is continuity between the movement road and a first road connected to an end point of the movement road. When the continuity determination unit determines that there is continuity between the first road and the movement road, the extension road setting unit sets the first road as a first extension road. The end point of the movement road functions as a reference end point, the movement road functions as a reference road, and the first road functions as a road to be determined.

Description

[0001] Cross-references to related applications [0002] The present invention is based on Japanese application number 2012-147004 filed on June 29, 2012, Japanese application number 2012-147002 filed on June 29, 2012, and Japanese application number 2013-091514 filed on April 24, 2013. The description content of them is quoted here. technical field [0003] The present invention relates to a navigation device for learning road sections, a navigation device for displaying the current location of an own vehicle on a map, and a program product for displaying the current location of an own vehicle on a map. Background technique [0004] Conventionally, in order to optimize the amount of guidance such as route guidance and Point of Interest (POI), technology has been disclosed that learns roads that users know. For example, in Patent Document 1, the road section that the user has actually traveled is learned as the road recognized by the user. [0005] In addition, as another ...
