Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention provides a navigation system for guiding a user to a destination via a waypoint on the way.ToIn particular, the present invention relates to route re-setting (re-routing) such as when the route previously set is departed during the movement.
[0002]
[Prior art]
  Conventionally, as a navigation system of this type, for example, as shown in Patent Document 1, the current location of a user who has a mobile device is specified using GPS (Global Positioning System) or the like. A device that guides a user to a target position in a predetermined area based on map data is known. In this device, information on the current position of the user specified by GPS or the like and information on the target position in the predetermined area are transmitted to the position management computer by the communication means, and from the current position to the target position by the position management computer. The guide route is determined with reference to the map data and transmitted to the portable device as guide information. Thereby, guidance information for reaching the target position can be given to the user reliably and in detail.

[0004]
[Problems to be solved by the invention]
  By the way, in general, when a user uses a navigation system, the user may go directly to a final destination or may go to a final destination after passing through a plurality of points. If it is used, it is possible to determine a useless route that reaches the destination as soon as possible while passing through all planned destinations by a conventionally known mathematical method based on the map information.
[0005]
  However, in the case of a system using a portable device as in the conventional example, once a set route is deviated during the movement, a new route from there to the destination should be set appropriately. There is a big problem that can not be. That is, in the case of a well-known car navigation system (hereinafter referred to as “car navigation system”), the current location of the user is continuously measured by GPS, and the user has information on the movement history. Even if it stops, the point that has been routed so far is clear, and a route from the current location to the destination via the unscheduled transit location may be set.
[0006]
  On the other hand, in general, in the case of a system using a portable device, it is necessary to suppress the power consumption in the portable device so as not to be compared with a car navigation system or the like, even if a GPS receiving circuit is mounted. As a result, it is not realistic to continuously measure the current location of the user, and therefore information on the continuous movement history of the user cannot be possessed. Therefore, when the user deviates from the route, it cannot be determined whether the user has been to the route planned place by that time. It cannot be set.
[0007]
  The present invention has been made in view of such a point, and the object of the present invention is to reduce the power consumption of the user terminal in the navigation system so that it can be applied to a mobile device while moving the user. Even if there is no history information, it is possible to improve the convenience of the user by enabling appropriate resetting of the route.
[0008]
[Means for Solving the Problems]
  In order to achieve the above-mentioned object, the present invention suppresses power consumption by not performing continuous positioning of the current location, and at the time of resetting the route, information on the current location obtained by positioning means, etc. Based on this, it is now possible to identify unscheduled via-routes even if there is no travel history information, so that appropriate routes to the destination can be reset.
[0009]
  Specifically, according to the first aspect of the present invention, when at least the destination and the planned route to that point are input to the terminal used by the user, the destination is routed through all the planned routes. When a predetermined positioning operation is performed at least on the terminal without continuously positioning the current location of the user for a navigation system that sets a route to reach and guides the user along this route When a predetermined route resetting operation is performed at a positioning means for performing positioning and a terminal used by the user, an unscheduled via route is identified without using information on the movement history of the user up to that point. And a route resetting means for setting a new route to the destination via the unscheduled via route destinationShall. The positioning unit has a function of displaying a map of the user's current location on the terminal, and the route resetting unit displays the current location on the terminal used by the user when the current location is displayed. Oh A route resetting operation is received, and when the route resetting operation is received, a list of planned destinations and destinations is selectably displayed on the terminal, and at least one unarrived point is designated by the user. To identify unscheduled transit locationsThe configuration.
[0010]
  With the above configuration, first, the user's current location can be specified by the positioning means, and continuous positioning by the positioning means is not performed, for example, continuous positioning like a car navigation system is performed. In comparison, the power consumption can be remarkably reduced.
[0011]
  In addition, when a route resetting operation is performed at the terminal, the route resetting unit has not yet arrived by the route resetting unit based on the current location information obtained by the positioning unit, even if there is no information on the movement history of the user up to that point. It is possible to specify the route planned place and set a new appropriate route to the destination via the route route that has not yet arrived.
[0012]
  In particular, The positioning meansTheThe route resetting unit accepts a route resetting operation at the terminal when the current location is being displayed on the terminal used by the user. things andBecausePrior to the resetting of the route, positioning of the current location is always performed, and it is possible to identify a planned transit location that has not arrived based on the information on the current location. Ie, The sutraWhen a route resetting operation is accepted, the route resetting means displays a list of route destinations and destinations in a selectable manner on the terminal, and allows the user to specify at least one unarrived point from among them, Identify unscheduled transit locationsThe
[0013]
  In this way, the user can easily specify a non-arrival point from the list of via-route destinations and destinations displayed in a list, thereby reliably specifying an unarrival via-route destination. In addition, since the current position is displayed on the map prior to the route resetting operation, the user can cancel a part of the planned via-route in consideration of the relationship with the current location. It is possible to set a more appropriate route reflecting the will of the person.
[0014]
  Note that when the user selects one unscheduled via-route place, the selected via-route place and all the subsequent via-route places in the arrival order may be specified as unarrived via planned places. Good.
[0015]
  Here, the route resetting means, when a predetermined arrival order changing operation is performed together with the route resetting operation at the terminal used by the user, changes the arrival order to the unscheduled via route according to this operation. Is preferred (claims)2Invention). When resetting the route, it is not the route that was set earlier, so it is better for the user to change the arrival order from the previous schedule, for example, to stop from the planned route closest to the current location at that time. This is because convenience may be improved.
[0016]
  Furthermore, it is preferable that the navigation system includes a computer device connected to a terminal used by a user via a network and capable of accessing at least a map information database.3Invention). In this case, the computer apparatus is provided with the route resetting means, and receives information on at least the destination and the planned route place transmitted from the terminal used by the user, and based on this information and at least the map information A route setting means for setting a route to reach the destination via all of the route planned destinations, and a terminal using the information of the route set by either the route setting means or the route resetting means And presenting means for transmitting and presenting. Further, the route resetting means, when receiving a request corresponding to the route resetting operation from the terminal used by the user, at least via the route planned location that has not arrived from the current location while referring to the map information A new route to the destination may be set.
[0017]
  In this way, it is not necessary for the user terminal to have a map information database, and the computation processing for route setting is performed by a computer device on the network, so the processing burden on the terminal side is extremely small. It will be a thing. Therefore, it can be easily applied to portable devices that can be carried, thereby improving convenience..
[0018]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a navigation system according to an embodiment of the present invention, and shows a state in which a server 1 (hereinafter referred to as a navigation server) that supports creation of a travel route (route to a destination) is connected to a user terminal 2. The navigation server 1 and the user terminal 2 are connected to each other via the Internet 6 (network) and the wireless communication antenna 7 so as to be able to communicate bidirectionally. The navigation server 1 is a server computer installed in the information center, and receives a request from the user terminal 2 to assist the user in creating a travel route as will be described later.
[0019]
  As shown in FIG. 2, the navigation server 1 includes a CPU 21 that performs control processing of various signals. The CPU 21 includes a communication interface 22 for communicating with the user terminal 2, and the navigation server 1. A ROM 23 that records a control program (navigation program) for controlling the image, a RAM 24 that temporarily stores various types of information, and a map database 25 that stores map information are connected to be able to exchange signals. The navigation program may be recorded on a recording medium such as a magnetic disk or an optical disk, and read by the CPU 21 via a disk drive device.
[0020]
  On the other hand, as shown in FIG. 3, the user terminal 2 includes a CPU 31 that performs control processing of various signals. The CPU 31 includes a display 33 that displays various information, and an operation switch 34 that is operated by a user. A communication device 35 that transmits and receives signals to and from the communication interface 22 of the navigation server 1, a ROM 36 that stores a program and the like for controlling the user terminal 2, and a RAM 37 that temporarily stores various information and the like. Are connected so that signals can be exchanged.
[0021]
  Further, the user terminal 2 is provided with a GPS module 38 in which a GPS (global positioning system) antenna and a receiving circuit are integrated, and a user performs a predetermined positioning operation (described later) by an operation switch 34. In response, the current location is determined. That is, the CPU 31 reads and executes the control program of the GPS module 38 from the ROM 36, and as is well known, using the carrier waves (radio waves) from a plurality of artificial satellites that can be captured from the current location, Get longitude and height information. Then, the information is displayed as a map on the display 33 of the terminal 2 (see FIGS. 11 to 13).
[0022]
  Furthermore, although the user terminal 2 is a mobile phone carried by the user in this embodiment, it may be a personal digital assistant (PDA) other than that. In addition, positioning by GPS may be performed intermittently after a certain period of time even when the user's operation is not performed. However, in mobile devices, it is extremely necessary to suppress power consumption. Because it is high, continuous positioning of the current location is not performed.
[0023]
  The CPU 21 of the navigation server 1 supports the creation of a travel route by the user by executing a navigation program. That is, the CPU 21 first inputs at least a travel destination and a scheduled route via the user terminal 2 and, when this information is transmitted from the user terminal 2, based on this information and at least the map information, A travel route to the destination via all of the planned route points is set (route setting step). Then, the travel route information is transmitted to the user terminal 2 and displayed on the display 33 as a map (presentation step).
[0024]
  Further, when a predetermined route resetting operation is performed at the user terminal 2 and a route reset request corresponding to this operation is transmitted from the user terminal 2, the CPU 21 of the navigation server 1 is mainly obtained by GPS. Based on the current location information, etc., even if there is no travel history information up to that point, the unscheduled via location is identified (unarrived via location identifying step), Then, a new route to the destination is searched and set (route reset step). Then, the new route information is transmitted to the user terminal 2 and displayed on the display 33 as a map (presenting step).
[0025]
  Hereinafter, the processing by the CPU 21 will be specifically described with reference to display examples on the display 33 of the user terminal 2 (FIGS. 4 to 13).
[0026]
  First, FIG. 4 shows an example of a top screen. This top screen is first displayed on the display 33 of the terminal 2 when the user terminal 2 is connected to the navigation server 1. The top screen includes various menu items. Each of these items is an operation button, and can be selected and operated by operating the input switch 34 of the user terminal 2. For example, “Drive Navi” supports travel route creation according to the user setting specific destinations and waypoints on the premise of traveling by car, while “Omakase Route” "", Instead of setting a specific destination, the user provides a candidate such as a destination from the navigation server 1 to the user terminal 2, and the user has selected from the provided candidates such as the destination A travel route is created by adopting something. In addition, “walking navigation” supports creation of a travel route on the premise of movement on foot.
[0027]
  Then, when the user selects, for example, “Drive Navi”, the travel route creation support process starts. First, as shown in FIG. 5, a screen for designating a departure place and a destination is displayed on the user terminal 2. It is displayed on the display 33. On this display screen, the user can select “departure place” and set, for example, the vicinity of the current location, a station, an airport, a port, or the like as the departure place. The user can also set the facility registered in the database as the departure place. However, in this embodiment, the user does not necessarily have to set the departure place, and the “departure place” is the current place by default. On the other hand, the “destination” must be set by the user, and this can be set in the same manner as the “departure place”. If “To TOP” is selected on the screen shown in FIG. 5, the top screen is displayed on the display 33 (the same applies to the following screens).
[0028]
  Then, if the user sets the departure point and the destination, a route search screen as shown in FIG. This route search screen is for setting search conditions for a travel route, and the set departure point and destination are displayed for confirmation by the user (in the example shown in the figure, the present location, the destination are shown as the departure points). As XX station). In addition, the route search screen includes “Departure point”, “Destination”, and “Via-point” operation buttons. When these operation buttons are selected, the departure point, destination, and so on are displayed. It is possible to change the planned route location (hereinafter also simply referred to as a transit location) or add a transit location.
[0029]
  Further, the route search screen includes a pull-down menu for “priority road conditions” and a pull-down menu for “route order designation”. The priority road condition setting is to set whether to use toll roads when moving from the departure point to the destination (including transit points). The menu selects either “toll road priority” or “general road priority”. The “toll road priority” is to create a travel route using a toll road, and the “general road priority” is to create a travel route that does not use a toll road.
[0030]
  In addition, the route order designation is to set the order in which multiple route points are routed. The pull-down menu for this “route point order designation” is “optimum route” or “via route number designation”. The user selects either one of "". The “optimal route” is the most efficient (the shortest travel distance and travel time) is created by ignoring the order of the number of each transit point (number of transit point 1, transit point 2, etc.). “By route number” is to create a travel route that goes through each waypoint in the order of the number.
[0031]
  Even when “Random Route” is selected on the top screen, the waypoint can be set after setting the departure point and the destination, as in the case of “Drive Navi”.
[0032]
  Then, when the user sets the departure point on the route search screen and performs selection operation of each pull-down menu, the navigation server 1 selects a travel route from the departure point to the destination based on the selected condition. The travel route information is searched and transmitted to the user terminal 2. In response to this, a route search result screen as shown in FIG. 7 is displayed on the display 33 of the user terminal 2. This route search result screen is a screen for presenting the outline of the created travel route to the user, and is “travel distance” (50 km in the example) as the total travel distance in the travel route, and “travel time” as the time required for travel. Each display (80 minutes in the example) is included.
[0033]
  Further, the route search result screen includes the display of the priority road condition selected on the route search screen (see FIG. 6), and in the example shown in FIG. Corresponding to this, an operation button “change to a general road” is displayed, and if this operation button is selected, the server 2 searches again for a travel route under the condition of “general road priority”. .
[0034]
  The route search result screen includes “S: present location” as a departure point, “G: XX station” as a destination, and “1: XX park” as a transit point 1 and a transit point 2. Each “2: OO Zoo” operation buttons are included. By selecting and operating each of these operation buttons, sightseeing information corresponding to the selected one is provided from the navigation server 1 to the user terminal 2.
[0035]
  These operation buttons are arranged in the order in which the user moves on the travel route, and the section from the departure point to the waypoint 1 (S- The travel distance and travel time (1 km) in the example (4 km, 12 minutes in the example), and between the waypoint 1 operation button and the waypoint 2 operation button, In the section 1-2, the travel distance and travel time (in the example shown, 30 km, 30 minutes) are further between the operation button at the waypoint 2 and the operation button at the destination. The travel distance and travel time (46 km, 38 minutes in the example) in (2-G section) are displayed.
[0036]
  The route search result screen includes operation buttons for “Register to route collection”, “Route weather”, “Send to friends”, and “Return to condition setting”. If the “Return” operation button is selected and operated, the route search screen is displayed on the display 33, resetting the starting point and destination, etc., and resetting the “priority road condition” and “route order designation” conditions. Setting is possible.
[0037]
  Further, the route search result screen includes an operation button “display route map”. When this operation button is selected, a route map screen as shown in FIG. 8 is displayed on the display 33. Is done. This route map screen includes an entire map showing the entire travel route. On this entire map, in addition to the thick line indicating the travel route, the sign of “S” indicating the departure place (current location) and , “G” indicating the destination “XX station”, “1” and “2” indicating “XX park” as the transit point 1 and “XX zoo” as the transit point 2 Each of the symbols is displayed.
[0038]
  In addition, the route map screen includes operation buttons “LEARN MORE!” For the above-described S-1 section, 1-2 section, and 2-G section. A corresponding section route map screen is displayed on the display 33. In addition, the display of the operation button of “Read more!” For each section is changed according to the travel route. For example, in the case where the travel route is only the departure place and the destination and there is no transit point, Omitted. For example, if the travel route has only the transit point 1 in addition to the departure point and the destination, only the operation buttons corresponding to the S-1 section and the 1-G section are displayed.
[0039]
  Each section route map screen of the S-1 section, 1-2 section, and 2-G section includes a section map showing only the corresponding section. FIG. 9 shows an S-1 section route map screen displayed on the display 33 of the user terminal 2 when, for example, the “Look in detail!” Operation button for the S-1 section is selected on the route map screen. The -1 section route map screen includes a section map of the S-1 section in which a travel route from the departure point to the waypoint 1 is indicated by a bold line.
[0040]
  Further, the “next” operation button is included in the S-1 section route map screen, and if this operation button is selected and operated, the next section of the S-1 section, which is the next section, from the intermediate point 1 to the intermediate point 2 is displayed. A 1-2 section route map screen (not shown) including the section map of the 1-2 section up to is displayed. Since the S-1 section route map screen shows the first section of the travel route, the operation button “Previous” is not displayed on this screen. Both “previous” and “next” operation buttons are included, and the S-1 section route map screen can be displayed by selecting and operating the “previous” operation button.
[0041]
  The S-1 section route map screen also includes an operation button “Look in detail!”. If this operation button is selected and operated, a detailed guidance screen (see FIG. 10) for a section obtained by further subdividing the section from the departure point to the waypoint 1 is displayed. The same applies to the 1-2 section route map screen and the 2-G section route map screen. The section detailed guidance screen shown in the drawing includes a detailed map showing a range including a predetermined number of intersections along the route among the intersections existing on the route from the departure point to the waypoint 1.
[0042]
  Each of the section route map screen and the section detail guidance screen includes an operation button “present location display”, and the user presses the operation button “present location display” on the screen using the operation switch 34 of the terminal 2. By performing the selection operation (predetermined positioning operation), positioning of the current location using the GPS module 38 is performed. Then, a current location display screen as shown in FIG. 11 is displayed on the display 33 of the user terminal 2. Similar to the route map screen (see FIG. 8), the current location display screen includes an entire map of the travel route. On this entire map, the departure place “S”, the waypoints “1” and “2” are displayed. In addition to the sign of destination “G”, a star mark indicating the current location of the user is displayed.
[0043]
  The current location display screen includes an item “Do you want to search again”, and this item includes operation buttons “Yes” and “No”. If the “No” operation button is selected, the screen returns to either the section route map screen or the section detail guidance screen, and each screen is displayed on the display 33, while the “Yes” operation button is selected. If operated, a route re-search screen as shown in FIG. In this route re-search screen, as in the route map screen, there is an entire map on which the departure place “S”, the transit points “1” and “2”, the destination “G”, and the current location symbol are displayed. include.
[0044]
  In the route re-search screen, radio buttons “S: departure place”, “to select and specify any one of the starting point, waypoint 1, waypoint 2 and destination point. 1: XX Park "," 2: XX Zoo "and" G: XX Station "are included, and the user selects and operates one of them, as described later. The ground can be specified. Further, the route re-search screen includes pull-down menus of “priority road condition” and “route place order designation”, respectively, as in the route search screen (see FIG. 6), and these conditions can be reset. It is like that.
[0045]
  Further, the route re-search screen includes an operation button for “re-search”, and when the user operates the operation button for “re-search” after designating an unarrived point by the radio button. Corresponding to this operation, the information on the selected point and the route re-search request by the user's radio button operation are transmitted from the user terminal 2 to the navigation server 1. In response to this, if the selected point is one of the transit points 1 and 2, the navigation server 1 selects the transit point in the order of arrival after that point (route point 1 and transit point 2 in the example). The route is identified as a non-arrival waypoint, and a new travel route that reaches the destination via these points is searched.
[0046]
  In other words, by specifying at least one point that has not arrived from among the points displayed in the list on the route re-search screen, it is possible to identify a route point that has not arrived even if there is no information on the movement history of the user. Thus, it is possible to determine a new travel route to the destination via the unarrived waypoint identified in this way without omission. Then, information on the travel route is transmitted from the navigation server 1 to the user terminal 2, and in response to this, a route re-search result screen as shown in FIG. 13 is displayed on the display 33 of the user terminal 2.
[0047]
  The route re-search result screen is a screen for presenting the outline of the newly created travel route to the user, and similarly to the route map screen shown in FIG. 8, the travel distance and travel time of the new travel route are displayed. The entire map showing the entire new travel route, and the “Look in detail!” Operation button for displaying the route map for each section from the current location to the destination are included (in the example shown, the current location To “1: XX Park”, “1: XX Park” to “2: XX Zoo”, and “2: XX Zoo” to “G: XX Station”. Is included)).
[0048]
  In this way, it is possible to newly set an appropriate travel route from the current location specified by the GPS to the destination “G” via all of the unscheduled transit locations (in this example, the transit locations 1 and 2). Even if the user once deviates from the set travel route, he / she can pass through the uninterrupted transit points 1 and 2 from the current location without any omissions and promptly reach the destination without making a detour. Can be reached.
[0049]
  In this embodiment, the CPU 21 of the navigation server 1 receives at least information related to the destination and waypoint from the user terminal 2, and based on this information and the map information, it passes through all the waypoints to the destination. When the user terminal 2 is displaying the current location by GPS in the route setting means for setting the route to reach, an operation for re-searching the route in the terminal 2 is accepted, and the display 33 of the terminal 2 A list of transit points and destinations is selectably displayed, and by specifying at least one unarrived point from among them by the user, the undeparted transit point is specified, and referring to the map information, A route resetting means for searching and setting a new route from the current location to all destinations that have not arrived, and the route setting means or the route resetting means Transmitting information of the set route by determining the deviation to the user terminal 2, and presentation means for displaying on the display 33 is constructed.
[0050]
  Therefore, according to the navigation system according to this embodiment, first, by the navigation server 1 connected to the user terminal 2 via the network, an appropriate travel is performed based on the information related to the user's destination or waypoint and the map information. The route is searched, and information on the travel route is transmitted to the user terminal 2 so that the map is displayed on the display 33. For this reason, it is not necessary for the user terminal 2 to be equipped with a map information database or the like, and the calculation process for searching for a travel route is performed by the CPU 21 of the server 1, so that the load on the CPU 31 of the user terminal 2 is extremely high. Therefore, it becomes easy to make a portable device that can carry the user terminal 2 as in this embodiment.
[0051]
  Further, since the user terminal 2 includes the GPS module 38 and displays the current location on the map, the user can easily grasp the relationship between the current location, the departure location, the waypoint, and the destination. .
[0052]
  Further, even if the GPS module 38 is provided in this way, continuous positioning is not performed by this, so that the power consumption is remarkably higher than that of continuous positioning such as car navigation. Can be reduced. This is extremely important when a mobile device is used as the user terminal 2.
[0053]
  Furthermore, as the most significant feature of the present invention, when a route re-search operation is performed at 2 in the user terminal, even if there is no information on the movement history up to that point, it is based on the current location information obtained by GPS, etc. Thus, it is possible to specify an unarrived route and newly set an appropriate route to reach the destination via the unarrived route.
[0054]
  That is, in this embodiment, the “present location display” operation is performed on the user terminal 2 and the current location display screen is displayed on the display 33, and “Do you want to search again” → “Yes” is performed on the screen. Then, a list of transit points and destinations is displayed on the subsequent route re-search screen so as to be selectable, and the user himself / herself designates at least one unarrived point. In this way, the user can easily specify an unarrived point from the list-displayed points, and the navigation server 1 can determine the unarrived waypoints based on the information on the points thus specified. It can be accurately identified.
[0055]
  In addition, prior to the execution of such a re-search, the user's current location is displayed on the entire map of the route re-search screen. It is also possible to cancel the transit point 1), which makes it possible to set a more appropriate travel route reflecting the user's will.
[0056]
  Thus, according to the navigation system of this embodiment, when the user deviates from the travel route while suppressing the power consumption of the user terminal 2 so as to be applicable to a portable device, the current location is measured by GPS, and the rest It is extremely convenient because a new travel route that reaches the destination via the route can be reset without omission.
[0057]
  In the above-described embodiment, when a travel route is re-searched, one non-arrival waypoint is designated by the user, and this waypoint (passage point 1 in the above example) is more than that. A transit point with a late arrival order (route point 2 in the above example) is identified as an unarrival transit point, and they are routed in the arrival order set earlier, but this is not restrictive. For example, if the route re-search screen is configured so that the arrival order of unarrival via points can be changed, for example, as shown in FIG. 14, the via point closest to the current location (in the example shown, via point 2) In some cases, the convenience of the user can be further improved by changing the arrival order such that the user stops at first and then travels to another destination (route 1 in the example in the figure) toward the destination..
[0058]
  Also,in frontIn the embodiment described above, the terminal used by the user is limited to the user terminal 2 which is a portable device. However, particularly regarding the setting of the first travel route before departure, the terminal used by the user is the user terminal 2. It is not limited to. That is, for setting the first travel route, the user can use a personal computer connected to the navigation server 1 via a telephone line or the like, or can use a car navigation system. .
[0059]
【The invention's effect】
  As described above, the navigation system according to the present invention has been described.ToAccording to the above, it is possible to specify the current location of the user by the positioning means, and it is practical to apply to mobile devices while suppressing power consumption by not performing continuous positioning by the positioning means. It can be. On the other hand, the information on the current location of the user obtained by the positioning means when the route is reset despite the fact that the user's movement history information is not obtained because continuous positioning is not performed. Based on the above, the route resetting means can identify the unscheduled via route, and set a new route to the destination via the unscheduled via route. Can be improved.
