In other words, the search information includes various information such as the prefecture name, municipality name, district name, point name, etc., guidance, and various information related to the store as a point, which are areas that are sequentially subdivided on the map information. The table structure has a tree structure in which item information is associated in a hierarchical manner. Then, for example, in response to a search request for search information set and input by the terminal input unit 130, stores, facilities, and the like are searched hierarchically based on item information and the like, and can be output as appropriate through screen display, audio output, or the like. Yes.

  The memory 170 stores setting items input by the terminal input unit 130, music data and image data, various information processed by the processing unit 180, and the like so that they can be read as appropriate. The memory 170 also stores various programs developed on an OS (Operating System) that controls the operation of the entire navigation apparatus 100. As the memory 170, it is desirable to use a memory having a configuration in which memory is retained even when the power is suddenly turned off due to a power failure, for example, a CMOS (Complementary Metal-Oxide Semiconductor) memory.

  The current position recognition unit 181 recognizes the current position of the vehicle. Specifically, a plurality of current pseudo positions of the vehicle are calculated based on the vehicle speed data and azimuth angle data output from the speed sensor and azimuth angle sensor of the sensor unit 110. Further, the current position recognizing means 181 recognizes the current pseudo coordinate value of the vehicle based on the GPS data related to the current position output from the GPS receiver. Then, the current position recognizing means 181 compares the calculated current pseudo position with the recognized current pseudo coordinate value, calculates the current position of the vehicle on the separately acquired map information, and recognizes the current position. .

  Further, the current position recognizing means 181 judges the inclination and height difference of the road on the basis of the acceleration data output from the acceleration sensor, calculates the current pseudo position of the vehicle, and recognizes the current position. That is, it is possible to accurately recognize the current position of the vehicle even at places that overlap on a plane such as a three-dimensional intersection or an expressway. In addition, when traveling on mountain roads and hills, the current distance is obtained by correcting the error between the travel distance obtained from speed data and azimuth angle data and the actual vehicle travel distance using the detected road slope. Recognize position.

  Note that the current position recognizing unit 181 can recognize, as the current position, the starting point that is set and input by the terminal input unit 130 as the pseudo current position, in addition to the vehicle current position described above. Various types of information obtained by the current position recognition unit 181 are stored in the memory 170 as appropriate.

  The destination recognizing unit 182 acquires destination information related to the destination set and input by an input operation of the terminal input unit 130, for example, and recognizes the position of the destination. As destination information to be set and input, various information for specifying a location such as coordinates such as latitude and longitude, an address, and a telephone number can be used. The destination information recognized by the destination recognition means 182 is stored in the memory 170 as appropriate.

  The traffic jam status recognition means 183 generates current traffic jam information related to the status of the traffic jam currently occurring. Specifically, the VICS data from the VICS output from the communication unit 120 is appropriately acquired. Then, based on the acquired VICS data, for example, based on traffic information regarding the traffic situation occurring in a region including the current position and the destination, or a predetermined range centered on the current position, recognize. In addition, the traffic jam situation recognition unit 183 calculates the time until it passes through the traffic jam section based on the traffic jam level, the traffic jam distance, and the like.

  The route processing means 184 is based on the setting item information for route setting set and inputted by the user and the map information stored in the storage means 160, and further considers traffic information according to the setting input. Then, the route search is performed by calculating the movement route to the destination of the vehicle. For example, a plurality of, for example, two moving route candidates are calculated based on various conditions such as the shortest time and the shortest distance in the setting item information for route setting, the presence / absence of toll road use, and the route without traffic congestion.

  The required time calculating means 185 calculates the required time for moving to the destination for each moving route candidate calculated by the route processing means 184. The calculation of the required time is performed not only for the total required time in the whole process to the destination but also for the continuous time corresponding to the movement to the destination. For example, the time required for movement is calculated for each of a plurality of intermediate points to the destination, for example, intersections in the real distance map information, and associated with each movement route candidate. Note that the required time is calculated based on terrain and each driving situation such as the position of the direction change such as a right or left turn or the position of the node N where the link L is switched to a different link L, not just an intersection as an intermediate point. Or, conversely, an intermediate point located every predetermined time may be associated with the required time. Furthermore, the required time calculation means 185 can calculate the required time not only by the moving distance but also by taking into account the traffic jam situation recognized by the traffic jam situation recognition means 183. That is, based on the degree of traffic information congestion, the distance at which traffic is jammed, etc., the time required to pass through the jammed section is calculated and added to the required time. The required time calculation means 185 also calculates the time difference of the time taken from the shortest travel route.

  The sound generation control means 186 is stored in the memory 170, and provides guidance related to vehicle movement based on the movement route information and feature guidance information acquired in advance corresponding to the vehicle driving condition, for example, contents for supporting vehicle driving. The guidance is notified by pronunciation by the voice output unit 150. For example, traffic information such as traffic conditions, feature information such as store information, etc. "700m ahead, right at the XX intersection in the direction of △△", "Departed from the travel route." . "," There is OO on the right side of 100m ", and the sound rises clearly from the sound of" Pong "from the speaker in the direction of turning as the turning angle approaches For example.

  For example, the display control unit 187 controls display of various display screens for prompting an input operation by the terminal input unit 130 and setting and inputting various information. Further, the display control unit 187 appropriately controls the terminal display unit 140 to display the real distance map information and the real time map information, and further calculates with the route processing unit 184 together with the real distance map information and the real time map information. The travel path candidate or the set travel path is displayed on the terminal display unit 140 in three-dimensional display, so-called 3D (3-Dimensional). This display form is appropriately switched and displayed by a predetermined input operation by the terminal input unit 130, for example.

  Specifically, when displaying the movement route together with the actual distance map information, the display control means 187 is three-dimensionally displayed as shown in FIG. 7, for example. For convenience of explanation, FIG. 7 shows a state in which two movement paths, that is, the movement path with the shortest time and the movement path with the second shortest time are displayed in a three-dimensional manner. The three-dimensional display shown in FIG. 7 uses the real distance map information as plane coordinates, intersects the real distance map information constituting the plane coordinates, for example, the Z axis direction which is the vertical direction passing through the current position is the axis of the required time. As shown in FIG. 8, as shown in FIG. 8, the terminal display unit 140 is controlled to provide a stereoscopic display so that the travel route candidates P1, P2 rise three-dimensionally in the Z-axis direction at the required time calculated by the required time calculating means 185. Let FIGS. 7 and 8 show examples of rising in the Z-axis direction in the required time for each predetermined distance. Further, for example, when there is a display request by an input operation of the terminal input unit 130, the moving route candidates K1 and K2 calculated by the route processing unit 184 are superimposed on the actual distance map information constituting the plane coordinates. Is displayed. In this display, as shown in FIG. 7, the movement path candidates K1 and K2 displayed on the real distance map information and the movement path candidates P1 and P2 that rise in the Z-axis direction taking the required time into consideration are Line segments between points corresponding to the Z-axis direction may be displayed continuously, for example, as a curtain. In the curtain-like three-dimensional display, it is preferable to display in a translucent state, such as a translucent state, so that a shadow area can be recognized from the viewpoint position.

  Further, when the moving route is displayed together with the real-time map information, for example, as shown in FIG. For convenience of explanation, FIG. 9 shows a state in which two movement paths, that is, the shortest movement path and the second shortest movement path, are displayed in a three-dimensional manner, as in FIGS. 7 and 8. The stereoscopic display shown in FIG. 9 uses the real-time map information as plane coordinates, intersects the real-time map information constituting the plane coordinates, for example, the Z-axis direction which is the vertical direction passing through the current position is the axis of the required time. As shown in FIG. 10, as shown in FIG. 10, the terminal display unit 140 is controlled by the time difference with the shortest time calculated by the required time calculation means 185 to control the terminal display unit 140 in a three-dimensional manner in the Z-axis direction. Display. That is, as shown in FIG. 10, the shortest travel path candidate P1 does not stand up in the Z-axis direction, and is superimposed on the real-time map information. FIG. 9 and FIG. 10 show examples of rising in the Z-axis direction with a time difference in required time for each predetermined distance. Note that the stereoscopic display using the real-time map information may be configured to superimpose and display the movement route candidate K2 calculated by the route processing unit 184 on the real-time map information, as in FIGS. Further, a three-dimensional display such as a curtain may be performed.

  Further, the display control unit 187 controls the terminal display unit 140 to change the viewpoint position, such as a state in which the stereoscopic display displayed on the terminal display unit 140 is rotated by a predetermined input operation by the terminal input unit 130, for example. To change the display state.

  The time measuring means 188 measures the current time based on a reference pulse such as an internal clock. Then, the time measuring means 188 appropriately outputs time information regarding the recognized current time.

[Operation of navigation device]
Next, the operation of the navigation device 100 will be described with reference to the drawings. In addition, as an operation | movement, although illustrated about the process which sets two movement paths on the time priority conditions to the destination, it is not restricted to this. FIG. 11 is a flowchart showing an operation of setting a movement route in the navigation device and performing a guidance guidance process. FIG. 12 is a conceptual diagram schematically showing a stereoscopic display screen in the real distance map information of the set travel route.

  First, when a passenger who is a user on the vehicle turns on the power of the navigation device 100 and supplies power, the processing unit 180 controls the terminal display unit 140 to display a main menu. That is, the terminal display unit 140 displays a display screen that prompts the user to input settings for content that the navigation device 100 operates. When the processing unit 180 recognizes an input operation for displaying map information from the main menu, the display control unit 187 performs processing for displaying the map information on the terminal display unit 140. At the time of this display, although details will be described later, the display control means 187 recognizes the vehicle position and displays the vehicle position icon superimposed on the map information of a predetermined scale ratio. In addition, the processing unit 180 performs processing for acquiring traffic information by the communication unit 120 by supplying electric power, and recognizes a traveling state by the sensor unit 110.

  Then, based on the main menu, when the user performs an input operation of the terminal input unit 130, as shown in FIG. 11, for example, a setting input is performed to perform a search process of a moving route for moving. When the processing unit 180 recognizes a setting input for performing the travel route search processing (step S101), the processing unit 180 determines various information necessary for the travel route search, for example, the destination, the shortest distance or the shortest time. The terminal display unit 140 displays a display screen that prompts input of setting information such as setting item information.

  Further, when the processing unit 180 recognizes various information necessary for the search for the movement route based on the input operation of the terminal input unit 130, the processing unit 180 first performs processing for recognizing the current position by the current position recognition unit 181 (step S102). The destination recognition unit 182 recognizes the destination set and input (step S103). Furthermore, the processing unit 180 controls the terminal display unit 140 to display a display prompting an input operation of setting items that are conditions for searching for a moving route. Then, when the user sets and inputs the setting items by the input operation of the terminal input unit 130 in accordance with the instruction on the displayed display screen, the processing unit 180 acquires the setting item information regarding the setting items that have been set and input (step S104). . The acquired current position information, destination information, and setting item information are stored in the memory 170 as appropriate.

  Thereafter, the processing unit 180 uses the route processing unit 184 based on the current position information, the destination information, the setting item information stored in the memory 170, and the traffic jam information recognized by the traffic jam situation recognition unit 183. Route search processing for searching for a travel route from the current position to the destination using the travel distance search map information of the real distance map information stored in the real distance map information storage area 161 of the storage means 160 and the matching data MM. (Step S105).

  In step S305, a plurality of, for example, two travel routes, a travel route having the shortest time to the destination, and a travel route having the shortest time next are searched. Further, the required time calculation means 185 sequentially calculates the required time to the right and left turn, for example, which is the intermediate point of these travel routes, and calculates the total required time to the destination. When calculating the required time to the right / left turn point, the calculation is performed by appropriately adding traffic jam information according to the setting item information set and input by the terminal input unit 130. In this way, the display control means 187 is based on the travel route calculated by the route processing means 184 and the required time calculated by the required time calculation means 185, and corresponding real distance map information and real time corresponding to a predetermined scale ratio. The map information is appropriately read from the storage unit 160, and the travel route is displayed on the terminal display unit 140. As this display form, it is displayed by superimposing on the real distance map information set and inputted at the time of setting input of the search process of the movement route by a predetermined input operation by the terminal input unit 130, and superposed on the real time map information. The three-dimensional display as shown in FIG. 7 in which the required time is taken into account in the form, the real distance map information, and the three-dimensional display as shown in FIG. 9 in which the time difference of the required time is taken into account in the real-time map information are set.

  When the display control unit 187 recognizes a predetermined input operation by the terminal input unit 130, that is, a display request for the scheduled time to reach the destination, the display control unit 187 determines the current time measured by the time measuring unit 188 and the required time of the travel route. Based on this, the estimated time to reach the destination is calculated. Then, the display control means 187 displays, for example, each scheduled time calculated in a state adjacent to each moving route candidate as text.

  Further, the display control unit 187 displays a message requesting selection of any travel route by the terminal input unit 130. When any travel route is set based on this display, the travel route is superimposed on the map information and displayed on the screen. For example, when a display request for stereoscopic display in consideration of the required time is set by a predetermined input operation by the terminal input unit 130, the required time is set in the Z-axis direction using the real distance map information as plane coordinates as shown in FIG. The movement route P set as is displayed in three dimensions. FIG. 12 shows an example of a three-dimensional display like a curtain, similar to FIGS. 7 and 9. Note that in FIG. 12, in the case of stereoscopic display considering the movement distance, the stereoscopic display may be performed with the Z-axis direction as the movement distance.

  Then, the processing unit 180 recognizes the moving state of the vehicle based on the data output from the speed sensor, the azimuth angle sensor, and the acceleration sensor of the sensor unit 110 and the GPS data output from the GPS receiving unit. In the display form in which the movement route is displayed on the terminal display unit 140, in the case of a planar display form in which the movement route is superimposed on the real distance map information or the real time map information, Based on the position information, for example, an icon representing the current position is displayed so as to be superimposed on the display data VM in a state that is substantially the center in the display area of the terminal display unit 140. Further, in the display form in which the movement route is displayed in three dimensions, as shown in FIG. 12, for example, an icon A representing the current position is displayed superimposed on a point where the Z axis intersects in the display data VM. Specifically, the travel route P (K) from the current position to the destination in the recognized travel situation is sequentially calculated, or the route that has already traveled based on the travel route P (K) that has already been calculated and set is calculated. The remaining time required and the distance traveled are recognized by performing the removal process. In the case of the three-dimensional display shown in FIG. 12, the three-dimensional state is sequentially changed to a state where the current position information in the recognized moving state rises at a required time or moving distance according to the remaining moving distance from the destination. Display. Further, the processing unit 180 displays or audios guidance information related to the movement of the vehicle based on the recognized movement status and the route guidance information included in the movement route information related to the movement route by the sound generation control means 186 and the display control means 187. To guide the movement of the vehicle (step S106).

[Operational effects of navigation device]
As described above, in the above-described embodiment, the travel distance from the current position to the destination is searched using the real distance map information, and the real distance map information is used as the plane coordinates as shown in FIGS. The Z axis direction orthogonal to the actual distance map information is displayed as a three-dimensional display in a state in which the movement path rises with the required time or movement distance axis. For this reason, the user can easily recognize the required time and travel distance to the destination. Therefore, by displaying a plurality of movement route candidates in a three-dimensional manner during the movement route search process, the user can easily compare the differences in the movement distances, and can easily set an appropriate movement route.

  Further, the time differences among a plurality of movement route candidates are calculated, and as shown in FIG. 9, each movement route candidate rises with the real-time map information as plane coordinates and the Z-axis direction orthogonal to the real-time map information as the time difference axis. The state is displayed in 3D. For this reason, the user can easily recognize the time difference between the movement route candidates, and the user can easily set the movement route.

  Then, not only the total time required for the entire journey to the destination, but also the required time is calculated almost continuously corresponding to the movement to the destination, for example, the required time is calculated for each of several intermediate points to the destination. ing. For this reason, it is possible to calculate a substantially continuous required time of the movement route, and to easily perform a stereoscopic display based on the required time by a simple calculation method.

  Furthermore, it obtains the traffic information that is traffic information and calculates the required time in consideration of the traffic situation. Therefore, a moving route candidate that matches the actual movement is displayed, and a more appropriate moving route can be set.

  In addition, the movement route corresponding to the movement route displayed in three dimensions is superimposed and displayed on the plane coordinates, that is, the real distance map information and the real time map information. For this reason, the user can easily recognize the state of the movement route and can easily set a more appropriate movement state.

  Furthermore, the movement path displayed in three dimensions and the corresponding movement path superimposed on the plane coordinates are displayed in a curtain-like manner. For this reason, the user can more easily recognize the state of the movement route, and more easily set a more suitable movement route.

  Further, in the curtain-like three-dimensional display, the shadow area from the viewpoint position is recognizable and is displayed in a translucent state. For this reason, the part which becomes a shadow from the viewpoint position and cannot be recognized can be recognized, and a more appropriate movement route can be easily set.

  The viewpoint position in the stereoscopic display can be changed. For this reason, a portion that cannot be visually recognized because it overlaps, or in particular cannot be visually recognized from the viewpoint position by displaying a plurality of movement path candidates in a stereoscopic manner, can be confirmed by changing the viewpoint position so that the stereoscopic display is freely rotated. Therefore, even if the movement route is displayed in a three-dimensional manner, the entire process can be properly recognized reliably, and a more appropriate movement route can be easily set.

  Also, for example, as shown in FIG. 12, when the set movement route is displayed in a three-dimensional display and guided, the current position is sequentially recognized and the movement route from the current position to the destination is sequentially calculated and displayed. Can be displayed properly even if you change your travel status, move out of the travel route, or change traffic conditions, such as when you stop by a gas station. Is obtained. On the other hand, in the configuration in which the display is sequentially changed according to the movement situation based on the already set movement route, the calculation load can be reduced, and the change of the three-dimensional display corresponding to the movement situation becomes quick and easy, and a good three-dimensional display is achieved. Is obtained.

  Furthermore, by the input operation of the display request for the estimated arrival time by the terminal input unit 130, the estimated time to reach the destination is calculated based on the current time measured by the timing means 188 and the required time of the moving route, for example, Text is displayed adjacent to each moving route candidate. For this reason, the situation of each moving route candidate can be recognized more easily, and a more appropriate moving route can be easily set.

  Further, the stereoscopic display in the real distance map information shown in FIG. 7 and the stereoscopic display in the real-time map information shown in FIG. 9 are appropriately switched and displayed by a predetermined input operation by the terminal input unit 130. For this reason, the situation of the movement route can be recognized in many ways, and a more appropriate movement route can be easily set.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

  That is, the moving body is not limited to a vehicle, and can be applied to any moving body such as an airplane or a ship. The moving body indicates the current position of a user carried to use the terminal device. The user may be targeted by recognizing it as the current position. Furthermore, as described above, a configuration in which a user directly carries, or a mobile phone or a PHS (Personal Handyphone System) as a terminal device, a mobile phone or a PHS base station as a server device, and a mobile phone or PHS as a base. It can also be applied to a configuration for acquiring information from a station.

  Each function described above is constructed as a program. As described above, for example, hardware such as a circuit board or an element such as one IC (Integrated Circuit), a configuration in which each program configuration is separately constructed as a network, etc. It can be used in any form. In addition, handling can be facilitated and use can be easily expanded by adopting a configuration in which a computer or the like is read from a program or a separate recording medium so as to function as the above-described configuration.

  In addition, the configuration of navigation that guides and guides by setting a movement route has been described, but any form in which map information is simply displayed on a display device can be used. For example, as described above, a program is read by a personal computer, and a travel route is searched using real distance map information or real time map information based on a pseudo current position and a destination set and input on the personal computer, and a stereoscopic display is performed. You may make it. You may apply to the process which displays such map information.

  The navigation apparatus 100 that displays the stored map information and constructs the navigation function alone has been described. For example, the map information is appropriately acquired from the server apparatus including the map storage unit that stores the map information via the network. Then, a system configuration in which a moving route is calculated by a vehicle-mounted terminal device and displayed stereoscopically, or a server device that acquires current position information of a vehicle from a vehicle-mounted terminal device via a network calculates a movement route via the network. As a system configuration for transmitting to a terminal device and displaying the stereoscopic display on the terminal device, or a system configuration for generating map information in a stereoscopic display form on the basis of the movement route by the server device and transmitting it via the network so that the terminal device can display it Also good. With such a system configuration, the map configuration information can be centrally managed by the server device, and the configuration of the terminal device can be simplified, and further, the productivity can be improved and the cost can be easily reduced. Furthermore, the configuration of the terminal device can be simplified by performing processing for searching for a moving route and stereoscopic display on the server device.

  Here, as the network, the Internet, an intranet, a LAN (Local Area Network) based on a general-purpose protocol such as TCP / IP, a communication line network or a broadcast in which a plurality of base stations capable of transmitting and receiving information via a wireless medium constitute a network Examples include a network such as a network, and a wireless medium itself that is a medium for directly transmitting and receiving information between the terminal device and the server device. Here, any medium such as radio waves, light, sound waves, and electromagnetic waves can be applied as the wireless medium.

  And as a display means, for example, the structure which can see a display screen three-dimensionally by holography technology, the structure which can be seen three-dimensionally by using 3D glasses, and the display panel are laminated and made three-dimensionally visible. Any display device such as a configuration may be used.

  Moreover, although the real-time map information storage area 162 which memorize | stores real-time map information was provided and the structure using this real-time map information was demonstrated, real-time map information does not need to be preset. For example, using real distance map information, the travel route, required time, time difference, distance difference, etc. are calculated, and at the time of display, real time map information obtained by transforming the real distance map information into a scale based on the required time is used. It may be generated and displayed. With this configuration, the configuration of the storage unit 160 can be simplified. Further, real-time map information may be generated in consideration of traffic jam information, and the use can be easily expanded. Note that the real-time map information may be configured with only display data. On the other hand, in the configuration in which the real-time map information storage area 162 described above is provided, it is only necessary to use preset real-time map information, the processing load can be reduced, and the processing time can be easily increased. Three-dimensional display using map information can be easily performed.

  In addition, the plurality of movement route candidates and the set movement route P (K) have been described in a three-dimensional display. However, for example, each movement route candidate may be displayed in a three-dimensional display as shown in FIG. In addition, in the case where the set movement route is displayed in 3D, it has been described that the 3D display sequentially changes with the movement with the point where the Z-axis intersects as the current point. For example, as shown in FIG. The icon A representing the current position may move on the three-dimensional display of the route.

  In addition, the display form shown in FIG. 7 for displaying the required time as the Z-axis direction in the real distance map information and the display form shown in FIG. 9 for displaying the time difference as the Z-axis direction in the real-time map information can be switched and displayed. However, only one of them may be used. In addition to these, for example, as shown in FIG. 14, a distance difference with respect to the shortest travel route candidate is calculated based on the travel distances of the plurality of travel route candidates using the real distance map information as plane coordinates, and this distance is calculated. The display may be switched to a display form that stereoscopically displays the difference as the Z-axis direction. FIG. 14 shows an example of a three-dimensional display like a curtain, similar to FIGS. 7 and 9.

  Then, during the stereoscopic display, the movement route K or the movement route candidates K1, K2 corresponding to the movement path P or the movement route candidates P1, P2 displayed in a three-dimensional display are superimposed on the real distance map information or the real time map information. It does not have to be. Furthermore, it is not necessary to display curtains. Further, for example, the display may be switched to display or non-display by a predetermined input operation in the terminal input unit 130.

  In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.
