  As a conventional technique related to a navigation apparatus, a technique is known in which position information acquired by a mobile phone is transmitted to a navigation apparatus, and a destination is set based on the transmitted position information. According to this technology, it is possible to reduce the trouble of inputting position information or the like to the navigation device. That is, the destination can be set without setting the destination from the operation unit. However, in such a conventional technique, transmission of position information is mainly performed by infrared communication, and in this case, a setting for enabling infrared communication is required on the navigation device side each time.

  On the other hand, Bluetooth (registered trademark) is known as a technique related to wireless communication that enables information to be exchanged between adjacent devices using a frequency band of 2.4 GHz. In addition, navigation devices having a Bluetooth function are gradually spreading in navigation devices mounted on vehicles. Most of the navigation devices having a Bluetooth function that have been widely used in recent years are compatible with a so-called hands-free function in which a user (driver) can talk without holding a mobile phone while the vehicle is running. In addition, during the execution of the hands-free function, the navigation device and the mobile terminal are always connected by using a dedicated profile. In other words, in order to execute the hands-free function, it is necessary to always maintain a connection state. Therefore, when position information is transmitted from the mobile terminal to the navigation device using the Bluetooth function, it is required to be able to transmit the position information while ensuring the hands-free function.

  In the present invention, in view of the above-described problems, in a navigation device capable of setting a destination based on position information transmitted from a mobile terminal by wireless communication, a function already executed by wireless communication is ensured and navigation is performed. It is an object of the present invention to provide a technology related to a navigation device that reduces the destination setting operation on the device side as compared with the conventional device.

  In the present invention, in order to solve the above-described problem, when a transmission request for position information is made from the mobile terminal to the communication unit of the navigation device, a predetermined process being executed using the communication unit is interrupted, and the route search unit The navigation device is controlled so that the processing necessary for the route search based on the position information is executed.

  Specifically, the present invention is a navigation device that performs route search and can transmit / receive information to / from a portable terminal by wireless communication, and is capable of transmitting / receiving predetermined information to / from the portable terminal. A route search based on location information from the mobile terminal, an execution control unit that controls the navigation device so that predetermined processing according to predetermined information received by the communication unit is executed A route search unit. Then, when there is a request for transmission of the location information from the mobile terminal during execution of the predetermined process using the communication unit, the execution control unit interrupts the predetermined process being executed, and the route search The navigation device is controlled so that processing necessary for route search based on the position information by the unit is executed.

  According to the present invention, the route search is performed based on the position information sent from the mobile terminal, so the route search can be performed without setting the destination on the navigation device side. According to the present invention, the execution of the predetermined process using the communication unit is interrupted, and the process necessary for the route search is executed. In other words, the predetermined process being executed is interrupted, that is, only temporarily disconnected, and the interrupted function is resumed when the process necessary for the route search is completed. Therefore, according to the present invention, it is possible to automatically perform a route search while ensuring a function being executed that uses the communication unit. Furthermore, according to the present invention, since the route search of the navigation device is automatically executed based on the position information from the mobile terminal, for example, the mobile terminal of the person who is waiting is waiting for the mobile terminal of the driver of the vehicle By transmitting the location (current location) and further transferring the current location to the navigation device, the vehicle can be smoothly guided to the meeting location.

  The navigation device according to the present invention can perform route search and transmit / receive information to / from a mobile terminal by wireless communication. Transmission / reception of predetermined information is performed by the communication unit. The predetermined information includes not only data such as position information and music information, but also a common profile determined in advance for realizing predetermined processing between the navigation device and the portable terminal. Examples of the common profile include those that enable transmission / reception of position information between the portable terminal and the navigation device, and those that execute reproduction of received music information. The profile that enables transmission / reception of position information may include a command for setting a destination based on the transmitted / received position information. In addition, the navigation device according to the present invention can be suitably used as a navigation device mounted on a vehicle. In this case, a user (driver) holds a mobile terminal while the vehicle is traveling in a common profile. It is also possible to execute a so-called hands-free function that allows the user to make a call without having to. The location information is exemplified by longitude / latitude information on the longitude / latitude of the destination and the current location, and information on the name of the shop, but is not limited to these, and can be used for route search of the navigation device. Any information can be used.

The execution control unit controls the navigation device so that predetermined processing according to predetermined information received by the communication unit is executed. Controlling the navigation device means controlling each functional unit constituting the navigation device, for example, controlling a route searching unit constituting the navigation device. Each function unit includes a communication unit that transmits / receives predetermined information to / from a portable terminal, a route search unit that performs route search, a hands-free execution unit that performs a hands-free function, and a reproduction that executes reproduction of content such as music The part etc. are illustrated. Further, the predetermined processing includes processing performed by each functional unit constituting these navigation devices. That is, the predetermined process includes transmission / reception of predetermined information to / from a portable terminal performed by the communication unit,
Examples include a route search performed by the route search unit, a process for realizing a hands-free function by the hands-free execution unit, and the like. Note that the transmission / reception of the predetermined information is a process using the communication unit, but the process for realizing the hands-free function also corresponds to the process using the communication unit because a constant connection state is necessary.

  Here, in the navigation device according to the present invention, when there is a transmission request for the location information from the portable terminal during execution of the predetermined process using the communication unit, the execution control unit The processing is interrupted, and the navigation device is controlled so that processing necessary for route search based on the position information by the route search unit is executed. Thereby, according to this invention, while performing execution of the predetermined process in execution using a communication part, it becomes possible to perform a route search automatically. The term “interrupt” means to temporarily stop, and to resume when processing necessary for route search based on position information by the route search unit is completed. The completion of the processing necessary for the route search means, for example, that the reception of the position information is normally completed.

  Even if there is a predetermined process that is being executed using the communication unit, depending on the type (content) of the process that is being executed, the process will end immediately and may or may not be interrupted. It is also assumed that this is not possible. Therefore, the navigation device according to the present invention may further include a determination unit that determines a type of a predetermined process being executed. The case where the processing ends immediately and does not need to be interrupted is, for example, transmission / reception of information. On the other hand, the case where the process does not end immediately and the process needs to be interrupted is, for example, a process for realizing a hands-free function that needs to maintain a constantly connected state.

  Here, in the navigation device according to the present invention, the execution control unit, when executing a predetermined process using the communication unit, when there is a transmission request for the location information from the portable terminal, Is transmitted to the portable terminal via the communication unit, and the position information sent from the portable terminal after the transmission is transmitted via the communication unit. When the reception is completed, the completion of reception of the location information is transmitted to the portable terminal, and the navigation device is controlled so that the predetermined process using the communication unit executed before the interruption is resumed. You may make it do. The present invention is a more specific example of the contents of processing performed by the execution control unit described above, and can automatically execute a route search while ensuring a function being executed using the communication unit.

  As described above, the navigation apparatus according to the present invention is characterized in that a route search is automatically performed based on position information from a mobile terminal. Therefore, in order to make such characteristics clearer, in the navigation device according to the present invention, the route search unit receives the communication unit when the communication unit completes reception of the position information from the mobile terminal. Based on the position information, at least a destination may be set and a route search may be started. In the navigation device according to the present invention, the route search is automatically started after the destination is set, but it is also assumed that the position information is sequentially transmitted from the mobile terminal. In this case, for example, position information can be stored in the storage unit of the navigation device, and the route search can be sequentially performed. Setting at least the destination means that the current position can be set in addition to the destination.

As described above, the predetermined process according to the present invention includes a process for realizing a so-called hands-free function. However, when the hands-free function is executed, the connection state is always set due to the characteristics of the function. Need to be maintained. According to the navigation device of the present invention, even when such a function requiring constant connection has already been executed, it can be temporarily interrupted and resumed. Therefore, the navigation apparatus according to the present invention can be suitably used as a navigation apparatus having a function that requires such a constantly connected state, for example, a hands-free function.

  Here, Bluetooth (registered trademark) can be used as a wireless communication means in the navigation device according to the present invention. In Bluetooth, a predetermined process is usually executed using a common profile between devices. Therefore, in the navigation device according to the present invention, a common profile determined in advance between the navigation device and the mobile terminal may be used as the predetermined information.

When the transmission of the position information is started, the navigation device 2 notifies the portable terminal 3 of the reception of the position information and the reception completion in step S13. During reception of the position information, for example, a display such as “Communicating. Please wait until communication is completed” may be displayed on the display 25. FIG. 6 shows a display state of the display during communication. Such a display can be realized by causing the execution control unit 202 to display predetermined character information or the like on the display 25. In this aspect, “Cancel” is displayed on the display 25 in addition to the above. This “cancel” enables the transmission / reception of the position information to be interrupted. When the “cancel” portion displayed on the display 25 is touched by the user, the transmission / reception of the position information is interrupted. After the interruption, a display such as “data reception has been interrupted” may be displayed on the display 25 in order to notify the user that the transmission / reception of the position information has not been completed. In addition, when the location information cannot be obtained due to some reason, the display 25 displays “Could not communicate. Please operate again” to notify the user that the transmission / reception of the location information could not be completed. May be displayed. When the position information can be normally received, the mobile terminal 3 is notified of the completion of reception of the position information. When the notification of the completion of reception of the position information is completed, the process proceeds to step S05.

  In step S <b> 05, the mobile terminal 3 receives a notification of completion of reception of the position information, and transmits a command for terminating the transmission / reception of the position information (also referred to as an OPP disconnection command) to the navigation device 2. When the transmission of the OPP disconnection command is completed, the process proceeds to step S14.

  In step S <b> 14, the navigation device 2 receives the OPP disconnection command and notifies the mobile terminal 3 of the end of the OPP connection and the end of the OPP connection. When the notification of the end of the OPP connection is given, the process proceeds to step S06.

  In step S06, the portable terminal 3 receives a notification of the end of the OPP connection, and a hands-free connection command is transmitted to the navigation device 2. When the hands-free connection command is transmitted, the process proceeds to step S15. In step S15, the hands-free connection is resumed in the navigation device 2. When the position information is acquired again in the mobile terminal 3, the process from step S01 to step S06 is executed in the mobile terminal 3, and the process from step S11 to step S15 is executed in the navigation device 2.
