JP 2004-267478 A

  In a company or a home, it is conceivable that a plurality of people board a single vehicle and use the navigation device by a plurality of people. If multiple people send information to the navigation device, problems may occur. For example, this is a case where a plurality of destinations are set at the same estimated arrival time. In this case, even if the newly input information is simply prioritized and set as the destination, if the set destination is not what the user desires, the input operation must be performed again, which is inconvenient.

  Therefore, an object of the present invention is to provide a navigation device with improved usability.

  A navigation device according to the present invention includes a communication unit that receives information from a first portable terminal and a second portable terminal, and destination information included in information transmitted from the first portable communication terminal. Prepare. In addition, the navigation device includes a control unit. When the destination information included in the information transmitted from the second mobile communication terminal indicates a common destination, the control unit sets the location indicated by the destination information as the destination. In addition, the car navigation device includes a display unit that displays a route from the current location to the set destination.

  The present invention can provide a navigation device with improved usability.

  Embodiments of the present invention will be described below with reference to the drawings. As user usage information stored in the portable terminal, e-mail, PIM (Personal Information Manager: personal information management software) information, or the like is used. PIM information is information such as individual schedules and to-do lists used in PIM. The PIM information is not limited to an individual schedule or the like, but may be group action schedule information managed by groupware or the like. Mail includes not only electronic mail but also short messages transmitted and received through a public network.

  This navigation device is used by being mounted on a vehicle, for example. Hereinafter, the case where this navigation apparatus is mounted on a car and used as a car navigation apparatus will be described as an example.

  FIG. 1 is a block diagram illustrating an example of a configuration of a navigation device.

  In FIG. 1, a control device 110 is a device having, for example, a CPU 111 that performs arithmetic processing, a ROM 112 that stores programs, a RAM 113 that functions as a working memory, and the like, and is connected to the following devices.

  The band terminal communication device 120 communicates with the portable terminal in response to a request from the control device 110. The mobile terminal communication device 120 realizes near field communication and narrow area communication such as Bluetooth / Wireless LAN (Wireless Local Area Network). Here, it is assumed that both Bluetooth and Wireless LAN are provided.

  The position detection device 130 detects the current position of the vehicle in response to a request from the control device 110. As the position detection device 130, a GPS (Global Positioning System) 131 is used. In addition, a device that recognizes the current position from a received beacon may be used.

  The storage device 140 is, for example, a hard disk 141, an optical disk or the like, stores map information or the like, and transfers requested map information or the like to the control device 110 in response to a request from the control device 110. The storage device 140 stores the input movement schedule information. The movement schedule information includes destination information or both destination information and scheduled arrival date / time information.

  The display device 150 is a display using a liquid crystal display (LCD) 151 or an organic EL, and the route searched by the control device 110 in response to a request from the control device 110, the course, the traveling direction, and the map information acquired from the storage device 140, The current position, destination, desired arrival time, etc. are displayed.

  The input device 160 is used when the user inputs information directly to the navigation device. As the input device 160, for example, a keyboard, various buttons, soft keys, a touch panel, a voice input device, or the like is used.

  In the example shown in FIG. 1, the navigation device includes a display device, but the present invention is not limited to this. A display device and an audio output device may be provided separately from the navigation device. In this case, an output device that outputs route information to the display device or the audio output device is provided in the navigation device.

  FIG. 2 is a block diagram showing an example of the configuration of the mobile terminal according to the first embodiment of the present invention. In FIG. 2, the control device 210 is a control device having an arithmetic device such as a CPU 211 or an MPU, a ROM 212, a RAM 213, or the like, and when the mobile terminal communication device 210 is notified that a destination information request has been received, The destination information stored in 230 is transmitted using the mobile terminal communication device 210.

  In addition, when the wide area wireless network communication device 250 receives the destination information, the control device 210 stores the destination information in the storage device 230 and displays it on the display device 240. The destination information received by the wide area wireless network communication device 250 is a received mail including a character string for specifying a place, such as a place name, an address, a latitude / longitude, and a common name of the place. The control device 210 stores the destination information input to the input device 260 in the storage device 230 and displays it on the display device 240. The destination information input to the input device 260 is an e-mail including a specific character string transmitted by the wide area wireless network communication device 250 or PIM information. The mobile terminal communication device 220 confirms whether or not a destination information request has been received, notifies the control device 210 if it is received, and transmits the destination information in response to the request from the control device 210.

  As the mobile terminal communication device 220, Bluetooth or Wireless LAN (Wireless Local Area Network) is used. The storage device 230 is a storage device such as a memory, and stores destination information in response to a request from the control device 210, and transmits destination information in response to a request from the control device 210.

  The display device 240 is a liquid crystal display 241, an organic EL display, or the like, and displays the contents of an e-mail or the contents of a PIM in response to a request from the control device 210.

  The wide-area wireless communication device 250 transmits and receives mail in response to a request from the control device 210. As the wide area wireless communication device 230, for example, a mobile phone wireless system 251 is used.

  The input device 260 is a keypad 261 and notifies the control device 210 of input from the user.

  When the portable terminal used in the navigation system is used as a part of the navigation system for the first time, an initial setting is required with the navigation device. This corresponds to pairing when the mobile terminal communication device 120 uses Bluetooth, and corresponds to setting a common encryption key when using the wireless LAN.

  By performing the initial setting such as pairing, the user can establish communication with the navigation device without inputting an address unique to the navigation device such as a mail address. This improves usability. Note that a plurality of portable terminals can make initial settings for one navigation device. The navigation device performs processing such as assigning an ID to each of the initially set mobile terminals to distinguish individual mobile terminals.

  When using the navigation system, the user may have decided which mail to set the destination. In this case, the user can mark a mail used for setting the destination (FIG. 3). In the example of FIG. 3, when a received mail is being browsed, a mark is added using the “add mark” soft key. In addition, “add mark” may be added to the submenu items. A mark may be added even when a list of received mails is displayed. The method of adding a mark by the user is not limited to this example.

  A person who creates a mail to be transmitted to the mobile terminal can include a specific character string in the mail. For example, when creating a mail, character strings “(location)” and “(date and time)” can be entered in the mail before the character string indicating the meeting place and time in the mail text. A mode in which this specific character string is used in this system will be described later.

  Next, an example of processing for setting a destination and a waypoint using the electronic mail data of the mobile terminal 200 will be described with reference to FIGS. 4 and 5.

  When the destination of the navigation device is not set, the control device 110 selects whether to use Bluetooth or W-LAN as the mobile terminal communication device 120 (S401). Bluetooth is used by default, and W-LAN is used when it cannot communicate with the mobile terminal. The user may decide whether to use Bluetooth or W-LAN with priority, or both. Moreover, you may decide whether to use Bluetooth or W-LAN according to the portable terminal of the communication partner.

  The control device 110 of the navigation device checks whether or not a portable terminal that has been initially set and can be used as a part of the present system exists in the communicable range through the portable terminal communication device 120 (S402).

  Here, the communicable range may be the inside of the vehicle body. The communication range is changed by adjusting the intensity of the signal transmitted from the mobile terminal communication device 120. As a result, when a user wearing the mobile terminal 200 gets on the vehicle, an information transmission request is sent from the mobile terminal communication device 120 to the mobile terminal 200 and communication is performed. Further, the communicable range is not limited to the inside of the vehicle body, but may be a distance near the vehicle body and capable of communication. The vicinity of the vehicle body is, for example, a space within a distance of 3 m from the mobile terminal communication device 120. The communicable distance is a range where a signal from the mobile terminal communication device 120 can reach. Information can be transmitted and received before the user wearing the portable terminal 200 gets into the car, and the destination setting process can be started quickly.

  If there is a portable terminal 200 that can be used as a part of this system, the control unit 110 checks whether communication with the portable terminal 200 is possible. If communication is possible, a request is transmitted to transmit information to the mobile terminal 200, and a predetermined number of received mails stored in the storage device 230 of the mobile terminal 200 are received from the latest one (S403). If there are a plurality of mobile terminals 200, the navigation device 100 receives a predetermined number of mails from each mobile terminal 200. Here, the predetermined number of cases is 10. However, the user can arbitrarily set the number of cases. The user may set the navigation device to receive only the mail with the mark added. The received mail is stored in the storage device 140. If communication cannot be performed, the process proceeds to S412.

  Next, the navigation device extracts the information indicating the destination from the received mail and the information indicating the estimated arrival date and time, and selects the information used for setting the destination and the route from the extracted information (S404). . If it cannot be extracted, the process proceeds to S411.

  Here, an example of processing in which the control device 110 extracts destination information from the received mail will be described. The control device 110 performs extraction by analyzing the subject and the part corresponding to the text in the mail. The analysis is divided into destination information analysis and estimated arrival date and time analysis. For analysis of destination information, the control device 110 performs morphological analysis and syntax analysis on the mail body, and character strings that may indicate places such as place names, building names, addresses, store names, and latitude and longitude are displayed. Extract and do.

  In the extraction, if there is a received mail to which a mark is added by the user, the control device 110 may be configured to analyze only the marked mail. With this configuration, the car navigation device can surely and quickly perform the process of selecting the mail to be used for setting the destination.

  FIG. 6 shows an example of a specific character string included in the mail. When a specific character string is included in the mail, for example, a character string such as “(location)”, the character string after the specific character string is analyzed in preference to other parts in the mail. . As shown in FIG. 6, if “(place) Yokohama station” and “(date and time) 12:00” are described in the mail, the control device 110 analyzes this part in preference to other parts of the text. Then, a character string indicating the place and time of “Yokohama Station” and “12:00” is extracted. The user can also set the navigation device 100 so as to analyze only the mail text including a specific character string. If a specific character string is included in the mail, the character string immediately after that is likely to indicate the location. In general, the search operation takes time. By analyzing in this way, the control device 110 can quickly and reliably extract a character string indicating the destination from the received mail. In addition, by using a specific character string, an e-mail creator can mix information used for setting a destination into a normal sentence.

  There is a high possibility that a sentence including a character string such as “gathered in” or “let's go” in the mail contains a character string indicating a place. The navigation device 100 analyzes the sentence with priority over other locations.

  The navigation device 100 compares the extracted character string with the contents of the database stored in the storage device 140 to identify the location. In the database, as shown in FIG. 7, address information is stored as character strings indicating addresses / addresses such as prefectures, municipalities, and addresses. The number of character strings that indicate a city varies depending on the location. The character string indicating the address / address is stored in order from the character string indicating the wide range. Therefore, for example, the control device 110 can determine with reference to the database that the place represented by the character string “Totsuka XX Town” is included in the place indicated by the character string “Yokohama City”.

  In the database of FIG. 7, common names, place names, abbreviations, common names, building names, common names of buildings, and the like assigned to the places are stored. This name or the like may be registered by the user. Examples of names registered by the user include “home”, “home of XX”, and “XX school”. The name of the place and the name that can be registered by the user are not limited to one. Position information for using the place for route search is also stored. For example, information indicating latitude and longitude is used as the position information. The position information of the destination is obtained from the mail by comparing the character string in the mail with the character string stored in the database.

  The location may not be uniquely identified from a single character string. For example, a station named “Hakusan Station” cannot be determined from only the character string “Hakusan Station” in Tokyo, Kagawa Prefecture, or Niigata Prefecture. In such a case, the current position or the like acquired by the position detection device 130 may be compared with the candidate location indicated by the character string, and a closer location may be set as the destination.

  The character string indicating the estimated arrival time is extracted based on a character string 110 such as a number, a symbol such as “:”, and a character string such as “hour”, “minute”, and “day”.

  The control device 110 stores destination information and the like obtained by analyzing the mail in the storage device 140 as movement schedule information. The travel schedule information includes the destination, the estimated arrival date and time, and the ID of the mobile terminal 200 that has input the information. This ID identifies from which portable terminal 200 the destination information and estimated arrival time information are input. If the destination information or the like cannot be analyzed from the mail received from the portable terminal 200 and the movement schedule information is not stored, the process proceeds to S411.

  The control device 110 selects information to be used for setting the destination from the stored movement schedule information (S406). If there is a mark added to the user, the selection is given priority. If there is something close to the estimated arrival date, give it priority. If there is information common to a plurality of terminals, priority is given to it. Hereinafter, an example of the movement schedule information selection process will be described with reference to FIG.

  First, the control device 110 determines whether any of the received movement schedule information is marked (S501). If there is, the control device 110 excludes other travel schedule information from the destination candidates (S502).

  Next, the control device 110 determines whether or not there is only one stored travel schedule information with a mark (S503). If there is only one, the control device 110 sets it as the destination (S515).

  When there are a plurality of pieces of movement schedule information, the control device 110 also stores the arrival schedule date and time of the movement schedule information with a mark, and further determines whether there is movement schedule information whose arrival time is within 24 hours from the present. Determination is made (S504). The number of 24 hours may be changed according to the user setting.

  If there is no travel schedule information for the latest 24 hours, the presence / absence of a common destination input by a plurality of terminals is determined (S510). If it exists, the latest one received by the mobile terminal 200 is used for setting the destination (S513). The case where the destination is common includes not only the case where the destination is the same as one destination but also the case where a certain destination includes another destination. For example, when the destination input from one terminal is “Yokohama City” and the information input from another terminal is “Totsuka Ward”, the control device sets the destination to Totsuka Ward. This inclusion relationship is determined by the control device 110 with reference to the database shown in FIG.

  In S510, if there is no travel destination information for which a common destination is input by a plurality of terminals, the latest date and time when the mobile terminal 200 received the mail is set as the destination (S514).

  In S504, when there is information whose estimated arrival date / time is within 24 hours, the control device 110 temporarily sets a temporary destination or waypoint using the information (S505). In S505, there may be a plurality of items whose estimated arrival time is within 24 hours. In this case, the control device 110 sets the destination and waypoint so as to satisfy all the movement schedule information. The control device 110 searches for a route by setting the farthest arrival time as the final destination via the destinations with the closest arrival times in order. For example, if the movement schedule information that is input as “estimated arrival time, 12:00. Destination, Tokyo” and the movement schedule information that is “scheduled arrival time, 15:00. Destination, Yokohama station” are input. For example, the control device 110 sets a route to Yokohama Station via Tokyo Station.

  The control device 110 calculates whether all destinations and transit points can be reached according to the scheduled arrival date and time (S505). If you can reach all destinations and stopovers. The destination and waypoint are set as provisional settings (S512).

Here, there are cases where the route cannot be set unless the movement schedule information is selected. For example, there is a case where travel schedule information having the same arrival time and different destination information is input. Also, for example, there are a plurality of destinations, but the difference in estimated arrival times may be too short to reach the plurality of destinations. As a specific example, when scheduled movement information “estimated arrival time, 12:00. Destination, Tokyo station” and scheduled movement information “arrival scheduled time, 12:05. Destination, Yokohama station” are input. There is. In this case, it is necessary to select one of the plurality of movement schedule information.
First, the control device 110 checks whether or not movement schedule information indicating a common destination is input by the plurality of mobile terminals 200 (S507). If there is something that is close to the scheduled arrival time and has the same destination information, the control device 110 sets the destination using the movement schedule information (S512). Each mobile terminal 200 is identified by the ID of the mobile terminal 200 in the database of FIG. If this function is used, even when a plurality of people use one car, the destination can be set with few operations. For example, the travel schedule information input from one mobile terminal 200 is “estimated arrival time, 12:00. Destination, Tokyo station”, and the travel schedule information input from another mobile terminal 200 is “scheduled arrival time”. Time, 12:00. Destination, Tokyo Station ”, and the movement schedule information input from another mobile terminal 200 is“ estimated arrival time, 12:00. Destination, Yokohama Station ”. In this case, the control device 110 sets the destination using the scheduled movement information “scheduled arrival time, 12:00, destination, Tokyo station”. For example, when a plurality of users have received an email having the same content, the location indicated by the destination information included in the email is set as the destination.

  The control device 110 assigns priorities to the mobile terminals 200 in the descending order of the usage frequency of the navigation device 100 and stores them in the storage device 140. If the control device 110 cannot select the destination information in S507, the travel schedule information input from the mobile terminal 200 having a higher priority is used for setting the destination (S508). Here, the usage frequency is determined by counting how many times information is transmitted from the portable terminal 200 to the navigation device 100 in a predetermined period.

If the destination cannot be set in S508, a plurality of pieces of movement schedule information whose estimated arrival time is included in a certain range are displayed on the display device 150 and selected by the user. (S509)
Through the above processing, what is desirable as the destination setting from the movement schedule information is set as the destination and set as the route (S407). Dijkstra method, A algorithm, etc. are used for route search.

  Next, route information for guiding the route / route to the destination is displayed on the display device 150 (S408).

  Even if the route is set, if the user of the navigation device 100 wants to change the destination, the user can input to the navigation device 100 to cancel the destination (S409). Further, a configuration may be adopted in which the user confirms the destination before the route information is displayed.

  When a change is input from the user, the control device 110 inquires of the user whether or not to directly select a mail to be used for destination setting through the display device 150 (S411).

  When selecting directly, the control apparatus 110 displays a mail subject list on the display apparatus 150 (S421). FIG. 8 shows an example of the display in S421, in which the subject of the mail, the date and time when the mobile terminal 200 received the mail, a list of senders who sent the mail to the mobile terminal 200, a cursor, and the like are displayed. The user selects an email to be used for destination setting from the list using the input device 160 (S422). Next, the control device 110 displays the acquired mail text on the display device 150 (S423). The user acquires and inputs destination information from the content of the mail text displayed on the display device 150 (S424). An example in which the user inputs destination information in S424 will be described with reference to FIG. The mail selected in S422 is displayed on the display device 150 (FIG. 9 (a)). The display device 150 displays a cursor for instructing the text of the mail and the character string to be input. The user designates the start point of the character string used for input with the cursor and the input device 160 (FIG. 9B), determines the range of the character string (FIG. 9C), designates the end point, and confirms the input ( FIG. 9 (d)). Similarly, the estimated arrival time is instructed and confirmed (FIG. 9 (e)). Further, by using a touch panel used together with the display device 150 as the input device 160, by moving a finger or the like while pressing it on the display from the start point to the end point of the character string input as destination information from the displayed mail text. It may be designated as destination information (FIGS. 10A and 10B).

  When the mail is not directly selected, the destination information is directly input using the user input device 160 (S412).

  As a result, when the destination information is input, a confirmation screen is displayed. FIG. 11 shows an example of a confirmation screen. A destination, a scheduled arrival time, a message for requesting a confirmation operation, and the like are displayed on the display device 150. When a confirmation operation is performed by the user, the control device 110 determines the desired arrival time from the map information stored in the storage device 140, the current position of the vehicle detected by the position detection device 130, and the destination position information. The optimum route for arriving at is searched (S413). Thereafter, the searched route, map information, vehicle current position, destination position information, and desired arrival time are displayed on the display device 150 (S414).

  In addition, even when the use of the car navigation device is terminated, the destination information with the estimated arrival time among the movement schedule information stored in the storage device 130 may be stored for a predetermined period. The predetermined period may be a period until the scheduled arrival date / time has elapsed for the movement schedule information including the estimated arrival date / time. In addition, movement schedule information that does not include the estimated arrival date and time may be 168 hours after input. If the user gets on the vehicle at a later date, the destination may be set using the movement schedule information input at that time and the movement schedule information previously stored in the storage device 140.

  According to this embodiment, the user can set the destination of the car navigation device without performing any operation. Even if the destination cannot be set, the user can set the destination with few operations. Further, when the user portable terminal 200 is operated, an appropriate destination can be set with few operations if it is attached to an e-mail used for destination setting in advance. Further, if the mobile terminal 200 receives the destination information as an email including a specific character string, the navigation device 100 can analyze the destination information more reliably. Also, when a plurality of information is sent from the mobile terminal 200 or when information is sent from a plurality of users, the navigation device 100 is suitable for use in setting a destination from the plurality of information. Information can be selected.

  In S403, when a predetermined number of mails are received, only the part related to “subject” and the part indicating the presence or absence of a mark may be received. In this case, if a specific character string is included in the subject by the user or if there is a mail with a mark, the navigation apparatus 100 acquires the mail text. The specific character string here is, for example, “(gathering)” or “(gathering)”. By receiving a part of the mail first, communication time and power consumption can be reduced.

  In this embodiment, a case where a specific character string is included in the mail is described. It is good also as a structure which adds the information which shows the location of the character string which shows the place in mail to a mail by a user. In this case, the control device 110 determines the location of the character string indicating the location based on the added information, and extracts destination information and the like.

  Further, instead of the mobile terminal communication device 120, a removable wide area network communication module may be used. FIG. 12 is a block diagram showing the configuration of the navigation device 100 in this case. The same parts as those in FIG. The control device 110 can use wide area wireless network communication by using the wide area wireless network communication module 170 connected to the navigation apparatus 100, and an e-mail transmitted to an e-mail address assigned to the wide area wireless network communication module 170. Can be used. The wide area wireless network communication module 170 performs communication through the wide area wireless network in response to a request from the control device 110.

  As the wide area wireless network communication system used by the wide area wireless network communication module 170, a mobile phone wireless system is used. The e-mail used for setting the destination is stored not only in the e-mail addressed to the e-mail address assigned to the wide area wireless network communication module 170 but also in the portable terminal 200 with which the portable terminal communication device 120 can communicate. E-mail may be good. The specific operation is the same as that of the first embodiment except that communication with the wide area wireless network communication module 170 is added to the communication method options in the portable terminal communication selection (S401) of FIG. The wide-area wireless communication module 170 may be a mobile terminal connected to a car navigation apparatus using a harness or the like.

  In the above embodiment, it is assumed that e-mail is used. However, the same applies to the case where PIM information is used. When PIM information is transmitted to the portable terminal 200 using a wide area wireless network, it is attached to the e-mail. Send. PIM information is often written in a specific format. Therefore, the control device 110 can extract the estimated arrival date and destination information and the destination information more easily than extracting from the mail.
