Effects of the present invention (1) Since map information with a resolution corresponding to the search time and/or map information playback speed of the map information recording medium playback device and approximately the moving speed of the moving body is recorded on the map information recording medium, the movement This is a navigation device that can give directions to the pilot in real time, sequentially following the optimal route according to the movement of the body.

(2) Map information with a plurality of resolutions corresponding to a plurality of approximate moving speeds corresponding to the moving route of the moving object, and map information with corresponding resolutions depending on the moving speed and/or route of the moving object, to a map information recording medium. Therefore, it is possible to realize the navigation device that can handle a wide range of moving speeds.

(3) Since a plurality of substantially optimal routes corresponding to the same current location/same destination are recorded, a navigation device that appropriately reflects the driver's intentions can be realized.

(4) Since priority is given to the plurality of substantially optimal routes, the substantially optimal route can be specified even when there is no indication of the operator's intention.

(5) Since route guidance and/or marks of each station are displayed and selected by wireless communication from the key station and/or vehicle station, a navigation device with good operability can be realized.

6) Priority can be set for the plurality of substantially optimal routes depending on the driver's driving purpose, etc., so navigation can be performed in accordance with the purpose.

(7) Scenarios are written because one or more approximately optimal routes are recorded between the approximately optimal route of the upper resolution and any position corresponding to the approximately optimal route in a predetermined region and its vicinity corresponding to the lower resolution. and identification becomes efficient.

(8) Since a scenario in which the above-mentioned arbitrary position is set as the first return position of the moving body can be specified, the route can be confirmed by simulation.

(9) Since the outside area name is written in each arc surrounding an area of approximately predetermined size corresponding to each resolution, it is possible to easily shift from narrow-area absolute tracking to relative tracking when moving away from the travel route.

(10) Since the relative relationship of each position at each resolution is described, narrow-area absolute tracking at each resolution is possible, and position identification in areas where lower resolutions are not described on wide-area maps, etc. is possible.

(11) The standard required time/road distance for each regional scenario is recorded, so the standard required time/road distance is recorded according to the scenario specification.
The distance along the road can be calculated and displayed.

(12) The difference between the standard required time/distance for each current location scenario or each destination scenario and the standard required time/distance for each of the above-mentioned corresponding high-ranking scenarios is recorded, so it is possible to sequentially respond to the identification of lower-resolution scenarios. You can easily calculate and display the total standard travel time/total distance.

(13) Accurate estimated required time can be calculated because it is recalculated based on each required time information of a substantially optimal route such as a map information recording medium/wireless communication/storage medium, etc.

(I4) For example, the area name corresponding to the higher resolution is displayed on the outer periphery corresponding to the command executed when the area divided into predetermined areas is located at the boundary of the display screen, so even if the area is divided into a lower resolution, it can cover a wide area. A display suitable for grasping the approximate position of the diagram can be displayed.

(15) Various screen displays such as current position, 7th branch, branch position, etc. by various display commands according to the position of the moving object (signal, pedestrian bridge,
A destination bulletin board, etc.) can be created.

(16) Various screen displays (traffic lights, pedestrian bridges, destination bulletin boards, etc.) suitable for displaying the scenario can be created using various display commands corresponding to the scenario.

(17) A storage address can be processed based on the vicinity of the current location/near the destination of each map information and stored at a predetermined location in the storage device. .

(18)? Map information corresponding to the resolution of jj numbers can be combined and displayed on the screen/announcement.

(19) Map information with resolution corresponding to the character/figure/two-dimensional position displayed on the screen is displayed *β, so by specifying the position on the screen, the character/figure/two-dimensional position can be identified, and then the scenario/display Be able to specify the required resolution/area to be displayed.

(20)? ! Is it possible to run approximately the optimal route of the number with the corresponding running pattern? Since the information is stored together with the pattern display command, it is possible to specify the approximately optimal route and display the approximately optimal route at the same time.

(21) A plurality of substantially optimal routes can be identified and a plurality of substantially optimal routes can be displayed at the same time, making selection easy.

(22) Since each image data/each announcement data corresponding to each image display command/each announcement command is fertilized at the same time, each of the above-mentioned commands is immediately realized.

(23) Since the current location/destination and characters/figures of each decomposition are displayed, setting of the current location/destination becomes easy.

<24) Characters/figures of each resolution are selected for display and displayed/announced when the character/figure is located in the area/near the target object and/or at regular time intervals, making route selection easy.

(25) When a predetermined position is selected to display characters/figures corresponding to the current location/nearby, route selection is facilitated because the display/announcement is made when the current location/nearby changes and/or at regular intervals. .

(26) When a predetermined position for displaying characters/figures corresponding to the next branching point corresponding to each resolution of the scenario is selected, the display/announcement is made when the next branching point changes or/and at a fixed time. This makes route selection easy.

(27) When a predetermined position is selected to display characters/figures indicating the road ahead according to each resolution of the scenario:
Since the display/announcement is made when the road ahead changes and/or at regular intervals, route selection becomes easy.

(28) When the moving object travels outside the map information storage area, the position is estimated using lily navigation and when storing map information corresponding to the lower position, the position is specified using feature tracking and/or relative tracking. Therefore, even if the map information recording medium is not inserted, it is possible to set the optimum route without having to reset the current location.

<29) It is possible to efficiently specify the position to start tracking using map information with a resolution corresponding to the error predicted by the dead reckoning navigation.

(30) If you store multiple pieces of map information, the display screen corresponding to the lower resolution map information will be displayed on the display screen of your local resolution map information. Be able to do it.

(31) Since the map information of the lower resolution of the current position/next branch position/destination position is stored, the map information of the lower resolution map information is highly responsive to changes in the current position/destination position.

(32) While displaying a stored area of a lower resolution on the display screen, map information of the corresponding lower resolution can be displayed by selecting an area.

33) Since map information of multiple resolutions is stored in the same storage device, the circuit configuration is simplified.

(34) Map information of multiple resolutions is stored for 9 days, so it is possible to display/announce area names such as current position/next branch position/destination position, etc. as wide area name/narrow area name, etc.

(35) Display the road distance/standard required time (calculated including information from wireless communication/storage media) corresponding to each scenario.

36) The current location/year, month, day, hour, and minute are displayed as unset, so make sure to use a device that does not allow for erroneous operation.

(37) Diameter 5'3 guidance can be easily changed by displaying and selecting the direct/brief optimum route of the partner station in wireless communication.

(38) By displaying and selecting the destination/substantially optimal route specified by the inscription medium, the one-cabin route guidance can be easily changed.

(39) By shortening a portion of the specifically displayed substantially optimal route, the content of the display/announcement of the scheduled place for the first race can be displayed/announced in advance.

(40) The position at E8 is the current location; 5 Since multiple approximately optimal routes are recorded, 111
Route guidance can be performed while selecting a 0-order new approximately optimal route (
41) During route guidance to a destination on a slope different from the original destination, approximately optimal routes to the original destination are displayed sequentially according to the movement of the mobile object, so the route to the original destination is always displayed. Understand it.

(42) Detects and displays discrepancies with the year, month, day, hour, and current location information of the wireless communication partner station, and resets the settings by selection.

(43) Since all 2M double-sided display areas are made human-like, an easy-to-operate menu screen can be configured.

(44) Since the entire character/figure display area is a human canyon, a menu screen with good operability can be constructed.
