` [Detailed Description of the Invention]
` [0001]
` [Industrial Field of Application] The present invention
`relates to an on-vehicle and mobile navigation device
`(navigation system), and more particularly relates to a
`centralized information management navigation system.
` [0002]
` [Conventional Art] In recent years, development of so-
`called car navigation systems for giving course guidance to
`a driver in accordance with a course that has been set
`before
`driving
`has
`become
`prevalent.
` [0003] Conventionally, such car navigation systems and
`navigation systems that can be carried by people are
`generally realized using one component (there are products
`
`(2)
`
`JP H8-285613
`
`2
`wherein the display and the control unit are separate
`products, but these are seen as one component because they
`are installed together in the same location), and data
`management and the like is performed by a road network
`information map being stored on a storage medium such as
`a CD-ROM, memory card, and the like and directly stored
`in the navigation system. Furthermore, in conventional
`navigation systems, a road map of 25,000 to 1 or less
`detailed is generally used, and it is normal to only have
`road information of a specific reference (prefecture roads or
`the like).
` [0004]
` [Problem to be Solved by the Invention] The conven-
`tional navigation system above has the following problems.
`(1) When attempting to use a road network information
`map (for example, a scale of 1/2,500 or the like) at the level
`of a detailed residential map as map data, the amount of
`data is extremely large when compared to a road network
`information map (for example, a scale of 1/2,500 or the
`like) at the level of a road map, and a larger memory is
`required, which makes it extremely difficult to handle on
`each navigation system.
` [0005] (2) Therefore, a less detailed road map (25,000 to
`1 or even less detailed road map) is used in conventional
`navigation systems, but only general road guidance can be
`realized in this case. FIG. 8 illustrates this. Furthermore,
`FIG. 9 illustrates that because only the portion of the thick
`line has road network information on the road map, when
`attempting to realize route guidance using this, guidance is
`not possible between the information point of the nearest
`road network (2) from a current position (1) and between
`the information point of the nearest road network (3) from a
`destination (4).
` [0006] (3) Because road network information in the
`conventional navigation system only has road information
`of a specific reference (prefecture road and the like) or
`higher as described above, it is impossible to obtain the
`shortest route using a residential road or the like even if
`there is one, and it is impossible to give guidance. FIG. 10
`illustrates this. This is particularly unsuitable for navigation
`systems for pedestrians.
`[0007] (4) In the conventional navigation system, map data
`stored in a storage medium is bought, saved, and managed
`by a user, but it becomes necessary to repurchase if there is
`a new version of the map or the like, which requires a large
`amount of money. Additionally, such versions are only
`released once every several years and thus updates to the
`map which occur daily cannot be immediately reflected to
`the navigation system user.
` [0008] (5) Even when using a road network information
`map at the level of a residential map, when attempting to
`display such data in a manner that is easy to view on the
`display of the navigation system, it is only possible to
`display a narrow area because the display is small, which
`makes it even harder to understand because positional
`relationships become unclear. Furthermore, even if the
`scale is increased in an attempt to display even a slightly
`wider range on the display, the figures of the houses, roads,
`characters, and symbols are small and compressed, which
`makes it even more difficult to see.

`IPR2020-00408
`Apple EX1035 Page 3

`

`

`
`JP H8-285613
`
`3
` [0009] (6) Because a road network information map at
`the level of a residential map has a large amount of
`information, a user owns a large number of storage media
`because the region that can be stored in one storage
`medium (CD-ROM or memory card) is small. Furthermore,
`the number of storage media to replace during use also
`increases, which is inconvenient for the user.
` [0010] In light of the above, an object of the present
`invention is to use information at the level of a detailed
`residential map which takes in daily updates on a map to
`make it possible to edit and provide extremely in-depth
`route guidance in real time in a manner that is easy to view
`on a relatively small display, and to provide a centralized
`information management navigation system that can relieve
`the user of the burdens of saving and managing the map
`data and the like.
` [0011]
` [Means for Solving the Problem] As illustrated in FIG. 1,
`the centralized information management navigation system
`in the present invention is configured by a mobile terminal
`10 carried by a user and a center device 20 connected to the
`mobile terminal via a communication line 30, wherein: the
`mobile terminal 10 is provided with: display means 11 for
`displaying map data; start and destination position
`designation means 12 for designating a start position and
`destination position; current position obtaining means 13
`for obtaining a current position; map display control means
`14 for performing control for displaying map data on the
`display means 11; and sending and receiving means 15 for
`communicating with the center device 20, and the center
`device 20 comprises: a detailed road network information
`map (for example, a scale of 1/2,500) 21 at the level of a
`residential map; route search means 22 for searching for
`and obtaining a route to a destination by accessing the road
`network information map 21; surrounding map obtaining
`means 23 for obtaining a minimum amount of surrounding
`map data required for displaying on the display of the
`mobile terminal along the obtained route from the road
`network information map 21; map editing means 24 for
`performing a thinning of characters or thinning of building
`figures and the like to be able to display on the display of
`the terminal side in a manner that is easy to view; and
`sending and receiving means 25 for communicating with
`the mobile terminal 10.
` [0012] First, in the mobile terminal 10, the start and
`destination position designation means 12 designates a start
`position and a destination position, and respectively
`acquired coordinate data is transmitted to the center device
`20 using the sending and receiving means 15. In the center
`device 20, the sending and receiving means 25 receives
`coordinate data of the start position and destination position
`from the mobile terminal 10, and the route search means
`obtains a route by accessing the road network map
`information 21 based on this data. The surrounding map
`obtaining means 23 obtains a minimum amount of
`surrounding map data (figures, characters, symbols, and the
`like) required for displaying on the display of the mobile
`terminal 10 along this route from the road network
`information map 21, the map editing means 24 edits the
`characters or building figures
`in
`the obtained map
`information, and the sending and receiving means 25
`
`4
`transmits the edit results data to the mobile terminal side. In
`the mobile terminal 10, the sending and receiving means 15
`receives surrounding map data from the center device 20,
`and the map display control means 14 displays the current
`position obtained by the current position obtaining means
`13 or the surrounding map data focusing on the destination
`position on the display means 11.
` [0013]
` [Action] In the centralized information management
`navigation system of the present invention, the navigation
`system configuration is separated into a mobile terminal
`carried by a user and a center device connected to the
`mobile
`terminal via communication
`lines, and by
`transmitting a minimum amount of
`required map
`information to the mobile terminal from the center device,
`guidance is given for a route by relatively moving a map
`display along with the movement of the mobile terminal.
`[0014] This makes it possible to realize road network
`information at the level of a residential map in the limited
`memory of the mobile terminal, which is difficult to handle
`in the conventional navigation system, and obstacles such
`as figures or characters becoming compressed and difficult
`to see can be prevented because map editing is performed
`in the processing of the center device so that the map
`information is easy to view on the display of the mobile
`terminal.
` [0015] Furthermore, because a minimum amount of
`surrounding map data (figures, characters, and symbols)
`required for being displayed on the display of the mobile
`terminal along a set route are obtained from the road
`network information map on the center side in the
`processing in the center device, it is possible to realize a
`reduction of communication between the center device and
`the mobile terminal and a reduction of processing data on
`the
`center
`device
`and
`the mobile
`terminal.
` [0016] Additionally, the user is relieved from the burdens
`of managing and saving on the map storage medium
`because a road network information map at the level of a
`residential map
`is centrally managed and operated.
`Furthermore, modifications to the map that occur daily can
`be made simply by updating the road network information
`map centrally managed in the center device, and updated
`content can be instantly reflected to the user of the
`navigation system. Moreover, the user is not required to
`have a map storage medium at hand, and convenience is
`improved because a plurality of CD-ROMs separated by
`each region does not need to be switched while moving or
`the like.
` [0017]
` [Embodiments] One embodiment of the present invention
`will be described below with reference to drawings.
` [0018] FIG. 2 is a block diagram illustrating one
`embodiment of the center device of a system for carrying
`out the centralized information management navigation
`system according to the present invention. In FIG. 2, 200 is
`a CPU such as a microprocessor managing the control of
`the entire center device, 210 is an external storage unit such
`as a hard disk for storing a road network information map
`215 (corresponding to 21 in FIG. 1) at the level of a
`residential map, 220 is a route search unit (corresponding to
`22 in FIG. 1) for accessing the road network information
`
`IPR2020-00408
`Apple EX1035 Page 4
`
`

`

`
`
`
`
`5
`map 215 and obtaining a route to a destination, 230 is a
`surrounding map obtaining unit (corresponding to 23 in
`FIG. 1) for obtaining a minimum amount of surrounding
`map data (figures, characters, and symbols) required for
`being displayed on the display of a mobile terminal along
`this route from the road network information map 215, 240
`is a map editing unit (corresponding to 24 in FIG. 1) for
`performing a thinning of characters or thinning of building
`figures from the surrounding map data so that the map can
`be displayed on the display of the mobile terminal in a
`manner that is easy to view, and 250 is a sending and
`receiving unit (corresponding to 25 in FIG. 1) for
`performing the control and the like of a communication line
`30 for sending and receiving data with the mobile terminal.
`Note that the CPU 200 may also have the processing
`functions of the route search unit 220, surrounding map
`obtaining unit 230, and map editing unit 240.
` [0019] Here, the connection relationship of the roads is
`indicated by, for example, a graph structure in the road
`network information map 215 stored in the external storage
`unit 210, and data is used having various attributes relating
`to roads added thereto. The nodes of this graph structure
`indicate intersections, and the edges indicate roads. The
`roads have coordinate
`lists
`indicating name,
`level
`(indicating national highway, express way, and the like),
`length, width, and shape roads as the attribute values
`thereof, and the intersections have a name and coordinates
`as
`the attribute values
`thereof. These attributes are
`attributes that are required considering route searching and
`the like. Note that the curve points of roads and endpoints
`of roads
`that curve
`in an L-shape are considered
`intersections for convenience in addition to cross-shaped
`and T-shaped roads.
` [0020] Road network information in a graph structure is
`not only appropriate for expressing roads, but also has
`advantages such as being able to use knowledge of graph
`theory, and can therefore be considered to be data that
`forms the basis of all applications relating to maps
`(reference literature: Tanaka et. al “Extraction of Road
`Network via Road Tracking Algorithm,” Information
`Processing Society of Japan 45th National Convention, 1J-1
`(1992); and Horie et. al “Generation of Road Network from
`Vector Map” Shingakukai Spring Convention D-466
`(1994)).
` [0021] FIG. 3 is a block diagram illustrating one
`embodiment of the mobile device of the centralized
`information management navigation system according to
`the present invention. In FIG. 3, 300 is a CPU such as a
`microprocessor managing the control of the entire terminal,
`310 is a screen display device (corresponding to 11 in FIG.
`1) for displaying map data, and 220 is an input device
`(corresponding to 12 in FIG. 1) for designating a start
`position and a destination position. 330 is a current position
`obtaining unit (corresponding to 130 in FIG. 1) for
`obtaining current position coordinates of the mobile
`terminal, and is made up of a GPS 332 for obtaining current
`position coordinates of the mobile terminal, a travel
`distance sensor 334, a magnetic field sensor 336, and a
`sensor interface unit 338 for converting these sensor signals
`into signals that can be processed in the CPU 300. 340 is a
`map display control unit (corresponding to 14 in FIG. 1) for
`
`(4)
`
`JP H8-285613
`
`
`
`6
`performing control for displaying a map on a screen display
`device 310, and is made up of a map control unit that
`relatively moves a map display along with the movement of
`the mobile terminal focusing on the current position or
`destination position and displays an arrow or the like in the
`direction of travel, a graphic controller 344 for displaying
`map data on the screen display device 310 while being
`controlled by the map control unit 342, and a graphic
`memory 346 for storing map data. 350 is a sending and
`receiving unit (corresponding to 15 in FIG. 1) for
`performing the control and the like of a communication line
`for sending and receiving data with the center device. Note
`that the CPU 300 may also have a portion or all the
`functions of
`the map display control unit 340.
` [0022] FIG. 4 shows a flowchart of the mobile terminal
`side, and FIG. 5 shows a flowchart of the center device side.
`The operation of the embodiments in FIG. 2 and FIG. 3
`will be described with reference to the flowcharts in FIG. 4
`and FIG. 5.
` [0023] First, when processing begins, the user designates
`and inputs a start position and a destination position using
`the input device 320 on the mobile terminal side (step S1).
`The input device 320 may be a joystick, and the position
`may be designated using an address or the like. When a
`start position and destination position are obtained, the
`mobile terminal is connected to the center device via a
`communication line 30 using the sending and receiving unit
`350, and start position coordinate and destination position
`coordinate data is transmitted to the center device (step S2).
`Next, the flow transitions to the processing on the center
`side.
` [0024] Processing begins in the center device, which is
`always standing by, when there is a call from the mobile
`terminal side. The center device receives start position
`coordinate and destination position coordinate data from
`the mobile terminal using the sending and receiving unit
`250 (step S10), the route search unit 220 accesses the road
`network information map 215 in the external storage unit
`210 based on this coordinate information and searches and
`obtains a route from the start position to the destination
`position (step S11), and map data (characters, building
`figures, symbols, backgrounds or the like) in a range of X
`(m) on both sides of the obtained route is extracted from
`the road network information map 215 in the surrounding
`map obtaining unit 230 (step S12). Here, X is any
`predetermined value, and prescribes the minimum range of
`data required to fit onto the display on the mobile terminal
`side.
` [0025] FIG. 6 is a diagram describing the relationship of
`this route and the extracted map data, wherein 610 is the
`route, 620, which is surrounded by a broken line, is the map
`data (surrounding map data) extracted from the road
`network information map 215, and 630 is the size (display
`range) of the display.
` [0026] Next, the map editing unit 240 executes steps S13
`to S16 in the center device. First, a check is performed as to
`whether there is any overlapping of data when the extracted
`map data is displayed on the display of the mobile terminal
`side (step S11). If there is any overlap, one piece of the
`overlapping data is left and the other is removed (step S14).
`In such a case, a priority order (leaving symbols as much as
`
`IPR2020-00408
`Apple EX1035 Page 5
`
`

`

`
`
`
`
`7
`possible or the like) may be added to the deleted data. Steps
`S13 and S14 are looped until all overlap is gone. When the
`overlap is gone or if there wasn’t any in the first place, a
`check is then performed as to whether there is any
`compression of characters or building figures (they cannot
`be recognized because they are too small) when the map is
`displayed on the display of the mobile terminal (step S15).
`The check may be performed , for example, in accordance
`with the display capabilities of the display of the mobile
`terminal side so that a character height of a number of mm
`or less is removed for characters and symbols, and a
`building area of a number of m2 or less is removed for
`buildings. If there is any compression of the characters or
`building
`figures,
`these are
`removed
`(step S16).
` [0027] In this manner, the sending and receiving means
`250 transmits the road network information map data edited
`by the map editing unit 240 to the mobile terminal side
`(step S17). The processing on the center side is then
`complete, and it once again returns to a standby state.
` [0028] Meanwhile, the mobile terminal receives the road
`network information map data (route surrounding map
`data) transmitted by the sending and receiving unit 350
`from the center side, and disconnects from the center
`device (step S3). The received map data is stored in the
`graphic memory 346 of the map display control unit 340.
`Afterward, on the mobile terminal side, the current position
`coordinates where the mobile terminal exists is obtained in
`the current position obtaining unit 330 using the GPS 332,
`the travel distance sensor 334, and the magnetic field
`sensor 36 (step S4). The map control unit 342 of the map
`display control unit 340 determines whether it is near the
`destination using the current position coordinates obtained
`by the current position obtaining unit 330 and the
`destination position coordinates input from the input device
`320 (step S5). If it is not near the destination, the graphic
`controller 344 is controlled to display the surrounding map
`data on the screen display device 310 focusing on the
`current position, and a picture of an arrow or the like is
`displayed on the location of the current position pointing
`toward the direction of travel (step S6). Additionally, the
`map control unit 342 relatively moves map display data of
`the display along with the movement of the mobile terminal
`(step S7), and repeats this until this reaches an area near the
`destination. If it is near the destination, the map data is
`displayed focusing on the destination, and a picture of an
`arrow is displayed on the location of the current position
`pointing toward the direction of travel (step S8). This is
`repeated until the destination is reached, and processing is
`completed once the destination is reached (step S9).
` [0029] Note that when there are changes in the map
`information, it is possible for these to be instantly reflected
`to the navigation user of the mobile terminal simply by
`updating the road network information map 215 of the
`external storage unit 210 in FIG. 2.

`range corresponds to one of 630 in FIG. 6, and this display
`range sequentially moves along with the movement of the

` [Effect of the Invention] As described in detail above,
`according to the centralized information management
`navigation system of the present invention, it is possible to
`use information at the level of a detailed residential map
`which takes in daily updates on a map to edit and provide
`extremely in-depth route guidance in real time in a manner
`that is easy to view on a relatively small display, and it is
`possible to relieve the user of the burdens of saving and
`managing the map data.
