Abstract

<P>PROBLEM TO BE SOLVED: To provide own vehicle mark display device which can easily obtain attributes of the road on which the vehicle is currently being map-matched and which has high visibility and usefulness. <P>SOLUTION: This own vehicle mark display device has a running road attribute discriminator 1, which discriminates the attributes of the road (general roads, expressways, toll roads, etc.) on which the vehicle is currently being map-matched from the vehicle's current position information detected by a navigation device N, based on the current position, running direction and the road map data. The device has an own vehicle mark selecting section 2 which picks up own vehicle mark, matching the attribute of the road the vehicle is being map-matched, from own vehicle marks set in advance for each attribute of the road, and sends it out to the display controller 3 which is described later. Further, it has a display controller 3 which changes the display method so as to display own vehicle mark picked up by the selector 2 as the vehicle's mark to display on the display device D according to the attribute of the road the vehicle is running in a map. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  For example, in a navigation device that guides and guides a moving route of a moving body, the present invention can display the vehicle mark in a different display form according to the attribute (type) of the road that is currently map-matched. The present invention relates to an own vehicle mark display device, an own vehicle mark display method, and an own vehicle mark display program.

  In recent years, with the generalization of automobiles and the development of information processing technology, navigation devices represented by in-vehicle use are rapidly spreading. Such a navigation device uses a road map data stored in a DVD, HDD, or the like to display the current position (latitude, longitude, etc.) of the vehicle that is sequentially detected by a geomagnetic sensor, a vehicle speed sensor, a GPS sensor, and the like. In addition to being displayed on the screen, based on the route data included in the road map data, the optimum guidance route from the current position to the specified destination is calculated, and guidance is provided by specific display or voice synthesis. In general, in order to indicate the current position of the vehicle, the vehicle mark is displayed on a map displayed on a display device such as a display.

By the way, in the above-mentioned navigation apparatus, in the navigation device as described above, a technique is proposed in which the display color of the vehicle mark is changed to a preset color according to the altitude of the current position of the vehicle. ing.

  Next, the best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be specifically described with reference to the drawings. In addition, although this embodiment is realizable by controlling the computer provided with the peripheral device by the program, the implementation | achievement aspect of the hardware and program in this case can be variously changed. Further, the present invention can be grasped as a program as described above and a computer-readable storage medium storing such a program in addition to the vehicle mark display device and method. Therefore, in the following description, virtual circuit blocks that implement the functions of the present invention and this embodiment are used.

(1) Configuration As shown in FIG. 1, the vehicle mark display device according to the present embodiment is based on the current position information of the vehicle detected by the navigation device N or the like, and the road where the vehicle is currently map-matched. A traveling road attribute discriminating unit 1 that discriminates attributes (general roads, expressways, toll roads, etc.) based on the current position, traveling direction, road map data, etc., and a vehicle mark set in advance for each road attribute The vehicle mark selection unit 2 that selects the vehicle mark corresponding to the attribute of the road on which the vehicle is currently map-matched, and sends the information to the display control unit 3 to be described later, and the display device D Display that changes the display method as needed, such as displaying the vehicle mark selected by the vehicle mark selection unit 2 according to the attribute of the road on which the vehicle is map-matched as the vehicle mark to be displayed And a control unit 3.

  In addition, the road by which the map matching is carried out means the road where it is detected that the vehicle exists, such as a running road. In addition, any known technique can be applied to the traveling road type determination method in the traveling road attribute determination unit 1, and the method is not limited to a specific one. For example, it is possible to use a method of discriminating from the VICS reception signal, a method of discriminating that the vehicle has entered the expressway by receiving ETC radio waves from the tollgate on the expressway, and the like. The vehicle mark selection process in the vehicle mark selection unit 2 refers to, for example, road type data attached to each road stored in advance in the road map data and the vehicle mark corresponding thereto. Is executed.

Road attributes include general roads, highways (highways using ETC entry / exit information), free roads, toll roads, ground roads, elevated roads, one-way roads, two-way roads, national roads, prefectural roads, There are city roads, private roads, school roads, bus-only roads, etc. Also, as the display form of the own vehicle mark, it is possible to change the color, shape, size, pattern, etc. of the own vehicle mark, whether blinking or not. For example, if the road you are currently driving is a “general road”, the vehicle mark is displayed in “red”, and if it is a “highway”, it is displayed in “blue”. The display form is changed.
In addition, the structure of the navigation apparatus N is not specifically limited, What is necessary is just the thing which can acquire the present location information of the own vehicle and / or the classification of a traveling road.

(2) Operation Details of processing in the vehicle mark display device of the present embodiment having the above-described configuration will be described with reference to the flowchart of FIG.
First, the traveling road attribute discriminating unit 1 discriminates the attribute (type) of the road on which the vehicle is currently map-matched by checking against a map database or the like provided in the navigation device N (step 201).

  Subsequently, the own vehicle mark selection unit 2 selects an own vehicle mark set in advance for each attribute of the road on which the own vehicle is currently map-matched from the road map data (step 202). Then, the vehicle mark selected in step 202 is displayed as the vehicle mark displayed on the display device D (step 203). In addition, the specific content of this display method shall be preset for every road attribute as mentioned above.

  Next, it is determined whether or not the attribute of the road on which the vehicle is currently map-matched has changed (step 204). For example, the road of the road on which the vehicle is currently map-matched, such as entering a highway from a general road. If it is determined that the attribute has changed, the process returns to step 201 and the same processing as described above is performed. On the other hand, if it is determined that the attribute of the road on which the vehicle is currently map-matched has not changed, it is determined whether or not to end the display of the vehicle mark (step 205). , Step 204 to Step 205 are repeated.

(3) Effect According to the present embodiment as described above, for example, even in a place where a general road and a highway run in parallel up and down or left and right, the own vehicle according to the attribute of the road Since the mark is changed, it becomes possible to easily determine which road the vehicle is currently map-matched to.

(4) Other Embodiments The present invention is not limited to the above-described embodiment. In addition to the road attributes as described above, the road width is a road having a certain width or more and a road having a certain width or less. It can be set as appropriate, such as changing the display form of the vehicle mark. For example, if you enter a road that is narrower than the road you are currently driving, you can easily determine that the road has become narrower even if you are not used to driving by changing the display method of the vehicle mark. You can drive with confidence.
