JP 2004-102332 A

  In the above-described prior art, the in-vehicle device can be connected to the center server by using a mobile phone as a communication means, and receives an operation menu that matches the preferences of the user of the in-vehicle device from the center server.

  As described above, in the conventional technology, when the mobile terminal is linked with another device, only the communication function is provided, and main processing is generally executed by the other device of the linkage destination.

  However, as the processing capability of the mobile terminal device is improved, a configuration in which main processing is executed by the mobile terminal device and the cooperation destination device is used as a secondary device such as display output or audio output has been studied.

  Since it can be expected that the mobile terminal device is always around the user, the mobile terminal device functions as a main, so that an appropriate service can be selected and executed in accordance with changes in the situation around the user. . Further, by using the portable terminal device as the main, it is possible to reduce the cost of the cooperation destination device and to suppress the obsolete performance.

  Therefore, the realization of a mobile terminal device and a communication program that automatically select an appropriate operation based on a cooperation state with another device has been an important issue.

  The present invention has been made to solve the above-described problem, and in a mobile terminal device that operates in cooperation with an external device, a mobile terminal device that automatically selects an appropriate operation according to the state of cooperation with the external device. And its communication program.

  In order to solve the above-described problems and achieve the object, in the portable terminal device and the communication program according to the present invention, when information is transmitted to a predetermined communication destination using the second communication means, It is detected whether or not the first communication means for performing communication is connected. If the first communication means is not connected, information created from information about the own device is transmitted, and the first communication means is connected. In some cases, information created from information related to the communication partner of the first communication means and information related to the device itself is transmitted, and data suitable for the transmitted information is received from a predetermined communication destination.

  Whether the information about the communication partner of the first communication unit is acquired when the first communication unit is connected, and the information about the communication partner of the first communication unit is transmitted based on the acquired information. It may be configured to determine whether or not.

  Further, after receiving data suitable for the transmitted information, when outputting the data, the connection partner of the first communication means may be used as the output means.

  According to the present invention, the mobile terminal device and the communication program transmit different information according to the connection state with the other device that cooperates with the first communication function by the second communication function, and data that matches the transmitted information. Since it is received from a predetermined communication destination, there is an effect that it is possible to obtain a portable terminal device that automatically selects an appropriate operation according to the cooperation status with an external device and a communication program thereof.

  In addition, it is possible to establish a communication connection with the second communication destination only when necessary by selecting whether or not to request data by the second communication function based on the information about the counterpart device of the communication destination acquired by communication. It is possible to obtain a portable terminal device and a communication program thereof.

  In addition, after receiving data suitable for the transmitted information, when outputting the data, if the communication partner of the first communication means is used as the output means, the screen or speaker of the external device is used. There is an effect that it is possible to obtain a portable terminal device that performs output and its communication program.

  Exemplary embodiments of a communication program and a mobile terminal device according to the present invention will be explained below in detail with reference to the accompanying drawings.

1. First, an overview of the present invention will be described with reference to FIG. In the present invention, the mobile terminal 10 is connected to the server 20 via a mobile phone network provided by a mobile phone carrier. The cellular phone 10 transmits a profile such as identification information and position information of the terminal itself to the server 10 and receives data conforming to the transmitted profile from the server 20.

  In addition, the mobile terminal 10 has a communication function using Bluetooth, a USB cable, or the like, and can be connected to an external device such as an in-vehicle device mounted on the vehicle. When the mobile terminal 10 is not connected to the external device, the mobile terminal 10 transmits only the mobile phone profile that is the information of the mobile terminal 10 to the server. When the mobile terminal 10 is connected to the external device, the external terminal acquired from the external device is transmitted. Both the device information and the own terminal information are transmitted to the server 20.

  In the figure, when the mobile terminal 10 is connected to the vehicle C1, the mobile terminal 10 acquires information on the vehicle C1 or a vehicle profile that is information on an in-vehicle device mounted on the vehicle C1, and The information is transmitted to the server 20 together with the mobile phone profile that is information.

  In this way, the mobile terminal 10 transmits different information to the server 20 based on the connection state with the external device by short-range wireless, and receives data suitable for the transmitted information from the server 20, thereby The main feature of the present invention resides in that an appropriate operation is automatically selected according to the cooperation status.

2. Configuration Example of the Present Invention Next, the main functional configuration of the present invention will be described with reference to FIG. Although some of the functional elements in the present invention can be realized by software, in the configuration shown in the figure, it can be appropriately selected whether the function is realized by hardware or software.

  As shown in the figure, the mobile terminal 10 is connected to the center server 20 via a network N1 provided by a mobile phone carrier, and is connected to the in-vehicle device 40 by short-range wireless communication. In this embodiment, an example in which the mobile terminal 10 and the in-vehicle device 40 are connected by short-range wireless communication will be described. However, the present application is not limited to this mode, and other communication functions that can be executed simultaneously with communication with the network N1. If so, it is not limited to short-range wireless communication.

  The center server 20 includes a profile determination unit 21 and a provision data creation unit 22 therein. The profile determination unit 21 receives a profile via the network N1 and determines the content thereof. Then, the provision data creation unit 22 creates data that conforms to the profile as provision data, and transmits the provision data to the mobile terminal 10 via the network N1.

  The in-vehicle device 40 is a device mounted on a vehicle, and includes a main control unit 41, a short-range wireless communication unit 42, a profile storage unit 43, a display 44, and a speaker 45 therein.

  The main control unit 41 is a control unit that totally controls the in-vehicle device 40, and the short-range wireless communication unit 42 is a communication processing unit that performs wireless communication with the mobile terminal 2. The profile storage unit 43 is a storage unit that stores information about the in-vehicle device 40 and the vehicle as a vehicle profile, and the display 44 and the speaker 45 are output units that perform display output and audio output, respectively.

  The in-vehicle device 40 can transmit the vehicle profile stored in the profile storage unit 43 to the mobile terminal 10 by short-range wireless communication. Similarly, by outputting display data and audio data received by short-range wireless communication from the display 44 and the speaker 45, the mobile terminal 10 can function as an external output means.

  The mobile terminal 10 includes a main control unit 11, a short-range wireless communication unit 12, a profile storage unit 13, a line connection unit 16, a display 14, and a speaker 15 therein.

  The short-range wireless communication unit 12 is a first communication unit that wirelessly communicates with the in-vehicle device 40. On the other hand, the line connection unit 16 is a second communication unit that connects to the network N1. The profile storage unit 13 is a storage unit that stores information about the terminal as a mobile phone profile, and the display 14 and the speaker 15 are output units that perform display output and audio output, respectively.

  The main control unit 11 is a control unit that controls the mobile terminal 10 as a whole, and includes a wireless communication detection unit 11a, a request message creation unit 11b, and an output processing unit 11c.

  The wireless communication detection unit 11a is a communication detection unit that detects whether the short-range wireless communication unit 12 is communicating with the in-vehicle device 40 or not. The request message creating unit 11b selects a profile that the mobile terminal 10 transmits to the center server 20, and performs a process of creating a request message.

  Here, based on the detection result of the short-range wireless communication unit 12, the request message creating unit 11 b uses only the mobile phone profile stored in the profile 13 to connect to the center server 20 when not connected to the in-vehicle device 40. Create a request message to send. On the other hand, when connected to the in-vehicle device 40, the request message creation unit 11b uses the mobile phone profile stored in the profile storage unit 13 and the vehicle profile received from the in-vehicle device 40 to the center server 20 together. Create a request message to send.

  Since the center server 20 creates provision data that conforms to the profile of the received request message and transmits the provision data to the portable terminal 10, the portable terminal 10 communicates with the in-vehicle device 40 by receiving and processing the provision data. Different processing is executed depending on whether or not it is in the middle.

  The output processing unit 11 c is a processing unit that controls output from the mobile terminal 10. When the portable terminal 10 is not connected to the in-vehicle device 40, the output processing unit 11c performs output using the display 14 and the speaker 15. Further, when connected to the in-vehicle device 40, the output processing unit 11 c can also output using the display 44 and the speaker 45 of the in-vehicle device 40. Furthermore, when the output content assumes only the output from the in-vehicle device 40, the output content may be discarded when the output from the in-vehicle device 40 cannot be performed.

  Next, the processing operation of the mobile terminal 10 will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart for explaining processing contents when the mobile terminal 10 starts communication with the center server 20, and it is preferable to repeatedly execute the main process of the mobile terminal 10 or a part thereof.

  First, the mobile terminal 10 confirms whether or not it is connected to the in-vehicle device 40 from the output of the wireless communication detection unit 11a (step S101), and automatically when it is connected (step S101, Yes). Center connection processing (step S103) is executed.

  Further, even when the connection to the in-vehicle device 40 is not being made (No at Step S102), the center connection process (Step S103) is executed when an operation for requesting the center connection is received from the user (Yes at Step S102). To do.

  FIG. 4 is a flowchart for explaining a specific example of the center connection process. As shown in the figure, the mobile terminal 10 first determines whether or not it is connected to the in-vehicle device 40 (step S201). A vehicle profile is acquired (step S202).

  In addition, after acquiring the vehicle profile (step S202) or when not connected to the in-vehicle device (step S201, No), the mobile phone profile that is the profile of the mobile terminal is acquired (step S203).

  Then, a request message is created using the acquired profile and transmitted to the center server 20 (step S204).

  As a result, if data is sent from the center server (step S205, Yes), a process using the received data is executed (step S206), and the process is terminated.

  Next, specific application examples of the present invention will be described. FIG. 5 shows an example of processing when a menu for vehicle services such as navigation and position information is displayed on the display of the in-vehicle device 40.

  In a vehicle, various services such as navigation, location information, address book, and mail can be used using an in-vehicle device. Here, when one person owns a plurality of cars, the menu formats displayed on the in-vehicle devices 40 are different, and it is troublesome to learn how to use both. Also, even if you rent a car, it may be difficult to use because it is different from the in-vehicle menu of the vehicle you normally ride.

  Further, contrary to the case where a single person uses a plurality of vehicles, there are cases where a plurality of people drive a single car or ride for a plurality of purposes. For example, if you ride a car for business or ride as a personal means of transportation, it is necessary to display both the business menu and the personal menu on the in-vehicle device menu, and the contents in the address book In addition, information on customers visiting for business and information on personal acquaintances are stored in a mixed manner, making it difficult to use separately.

Therefore, as shown in FIG. 5, the mobile phone brought into the vehicle and the vehicle-mounted device are connected by short-range wireless communication such as Bluetooth, and the mobile phone and the center server are connected by the communication means of the carrier network. To display the menu for the in-vehicle device.
(1) Send the in-vehicle device profile to the mobile phone.
Note that as the vehicle profile, it is possible to set arbitrary information related to the vehicle and the vehicle-mounted device, such as vehicle type information for specifying the vehicle type and screen size information indicating the size of the display of the vehicle-mounted device.
(2) Mobile phone profile including user information and in-vehicle device profile are sent to the center server.
As the user profile, for example, arbitrary information related to the mobile terminal and the user such as model information indicating the type of the mobile terminal and a user ID for identifying the user can be set.
(3) Center server sends access information (URL) for menu retrieval
(4) Mobile phone accesses URL and takes out menu screen
(5) Menu screen creation (rendering) on a mobile phone
(6) Send the menu screen from the mobile phone to the in-vehicle device
(7) Display the menu screen on the in-vehicle device

  By such processing, a vehicle-mounted menu based on the profiles of the vehicle-mounted device and the mobile phone can be displayed.

  In addition, by providing a function to edit the screen layout of the in-vehicle menu for the mobile phone in the center server, the in-vehicle menu that suits the user can be displayed, and the same in-vehicle menu can be displayed when riding in another car become able to.

  Therefore, compared to a method in which the in-vehicle device displays the in-vehicle menu by itself, when one person rides on a plurality of vehicles, any vehicle can display the in-vehicle menu familiar to that person. Also, when a single car is driven by multiple people or when riding for multiple purposes such as business / personal use, the mobile phone brought into the car can be used separately for business use or personal use. A suitable in-vehicle menu can be displayed.

  Note that the processing of (3) to (5) in FIG. 5 does not have to be performed in this way. For example, menu screen data is transmitted from the center server to the mobile phone in (3), and (4) and ( By skipping the process of 5), the menu screen received in (6) may be transmitted from the mobile phone to the in-vehicle device.

  FIG. 6 shows an example of processing when an application is acquired from the center server. Mobile phones can use various applications such as email, navigation, and business support systems. However, it is dangerous to operate a mobile phone while driving, so these applications cannot be used in the car.

  Here, if an application that supports hands-free input / output, etc. is provided on the network, you can download it and use it in the car, but if you find it from the network and download it, you must start it. It is troublesome. In addition, other normal mobile phone applications can be used, which is dangerous.

  For example, if you download music to a mobile phone and get in your car, it is convenient if you listen to the music with in-car audio, but find and download an application that plays back the mobile phone music with in-car audio and launch it There is a need.

  For business-related applications, it is convenient to automatically set the navigation route to the address after getting on the car after confirming the customer's address to be visited with the mobile phone. Must.

  As described above, there has been a problem that it takes a lot of time and effort to use the mobile phone solution used outside the car in the car.

  Therefore, in the processing shown in FIG. 6, by connecting the in-vehicle device 40 and the mobile terminal 10 by short-range wireless communication, static information such as the type and size of the car and dynamic information such as the vehicle speed are used as the vehicle profile. Send from the in-vehicle device to the mobile phone. In addition, as the vehicle profile to be transmitted, any other information such as information regarding business, private use, rental car, weight, shift state, steering angle, and vehicle operation state can be used.

  In addition, the mobile terminal 10 and the center server 20 are connected via a carrier network, information on applications used in the mobile terminal 10 (for business use, private use, etc.), application usage history, whether or not to use in the car, and priority. The cellular phone profile such as the degree is transmitted to the center server 20 together with the vehicle profile. In addition, information relating to the owner of the mobile terminal such as driver's license information can also be handled as a mobile phone profile.

  The center server 20 determines from the vehicle and mobile phone profiles whether the user is in a business vehicle or a personal vehicle, and what is the in-vehicle solution to be provided now. Then, the in-vehicle application that matches that is transmitted to the mobile terminal 10.

  The mobile terminal 10 receives the in-vehicle application and starts automatically. Here, the input / output interface of the mobile terminal 10 is shared with that of the in-vehicle device 40 so that the mobile phone application can display the mobile phone application. In addition to this, it is desirable to make the normal mobile phone application used outside the vehicle unusable at the same time.

  By performing the processing in this manner, an in-vehicle solution is automatically provided from the vehicle profile and the mobile phone profile, and the mobile phone application can be used smoothly in the vehicle. Conventionally, a normal mobile phone application can be used even in a car, which is dangerous. However, in this system, the use of the normal mobile phone application is regulated and safe in the car.

  FIG. 7 is a processing example in information collection when performing navigation for a vehicle with a portable terminal. In recent years, navigation systems have been developed in which GPS is installed in a mobile phone and the position information is used. However, since GPS positioning is used for position information, it has been difficult to use in building shadows and tunnels with poor visibility.

  The in-vehicle navigation system implemented as an in-vehicle device receives a signal (vehicle speed sensor) that detects the vehicle speed from the vehicle, and realizes autonomous positioning by using vehicle speed sensor information and Map matching technology even in locations where GPS positioning is difficult. Complements

  Therefore, if vehicle speed information is input to a mobile phone, autonomous positioning with the same accuracy as navigation in an in-vehicle device should be possible.

  However, since the mobile phone does not know what kind of vehicle the user holding the mobile phone rides on, the pulse width and amount of movement of the vehicle speed sensor in that vehicle and the initial position of the vehicle are unknown. Therefore, in order to output actual correct information, it is necessary to measure the movement amount by the GPS positioning and the movement amount by the pulse width and to grasp the initial position by the GPS positioning, which requires a lot of time.

  By the way, the place where the vehicle stops and the place where it starts are basically the same place. (If the vehicle is not moved at the time of stopping, the position at the time of starting is the same as at the time of the last stop.) Therefore, the car navigation system mounted on the vehicle displays the position at the time of the final disconnection as it is when the power is turned on. I can do things.

  However, in the case of a navigation system mounted on a mobile phone, it is difficult to specify a vehicle. Therefore, by storing the last vehicle stop position measured by the mobile phone by the mobile phone or the center server, it is possible to grasp the initial position without taking much time at the next mobile phone connection.

  At that time, the vehicle-specific information, for example, the movement distance per vehicle speed pulse unit, is also stored, so that the position correction according to the vehicle can be performed in a shorter time.

  Specifically, when the mobile terminal 10 performs navigation, the final position and an ID for identifying the vehicle (on-vehicle device 40) and information such as a vehicle speed pulse interval are stored in association with each other, and the center server 20 Register with. And in-vehicle device 40 memorizes ID which identifies the last connected portable terminal as last link portable ID.

  Thereafter, when the mobile terminal 10 is again connected to the in-vehicle device 40 via a short-distance wireless connection, the final link mobile ID is acquired from the in-vehicle device 40, and the ID is compared with the ID of the own terminal. If the IDs match, it can be considered that the vehicle on which the in-vehicle device 40 is mounted has not moved from the position stored in the portable terminal 10 last time.

  In addition, when the last link mobile ID and the ID of the own terminal do not match, it is possible to move from the position stored last time by connecting to another mobile terminal (or the vehicle that the own terminal has not connected to in the past) Therefore, the vehicle position and the vehicle speed pulse interval are acquired from the center server 20.

  In the process of the portable terminal 10 in this case, first, a vehicle profile is acquired from the in-vehicle device 40 as shown in FIG. Then, the final link ID included in the vehicle profile is read, and the final link ID is compared with the ID of the own terminal.

  As a result, when the final link ID and the terminal ID match, the terminal position and the vehicle speed pulse stored in the terminal are read out and used for the navigation service, but the terminal link ID is different from the terminal ID. Is confirmed, the mobile terminal 10 transmits the vehicle profile and the mobile phone profile (including at least information for identifying the vehicle) to the center server 20 from the mobile terminal 10.

  The center server 20 searches for the final position information of the vehicle using the received information as a key, and transmits it to the mobile terminal 10.

  The mobile terminal 10 starts the navigation service using the acquired final position information as the current position. Here, the mobile terminal 10 performs the identification of the current position, the search for the planned travel route, the generation of the map screen output and the guidance voice output by the own terminal, but the output contents of the map screen output and the guidance voice output are stored in the in-vehicle device 40. It transmits by near field communication and outputs using the display and speaker of the in-vehicle device 40.

  By such processing, when there is no connection record with the vehicle or when the vehicle has traveled by connecting to another mobile terminal after connection with the own terminal, the initial position when performing the navigation processing is quickly determined. While setting, it can adapt to the difference for every vehicles, such as a vehicle speed pulse.

  Since the vehicle may travel without being connected to the mobile terminal and its stopping position may change, if the mobile terminal is not connected to the mobile terminal at the start of travel, it is set to clear the final link mobile ID. Also good.

  As described above, the mobile terminal 10 according to the present embodiment can be connected to an external device such as the in-vehicle device 40, and transmits different information to the server 20 based on the connection state, and conforms to the transmitted information. By receiving the received data from the server 20, an appropriate operation is automatically selected according to the cooperation status with the external device.

  Therefore, it is possible to automatically acquire operation menus and applications suitable for the connection destination device and the own terminal, and to appropriately acquire information necessary for speeding up services such as navigation.

  It should be noted that the configuration and operation shown in this embodiment are merely examples, and the present invention is not limited thereto and can be appropriately modified and implemented.

  For example, in the present embodiment, the case where the mobile terminal is connected to the in-vehicle device by a short-distance wireless connection has been described as an example. However, the mobile terminal may be an external device mounted on an arbitrary moving body such as a train, or a display or the like. A publicly available terminal may be used as an external device.

  Further, in the present embodiment, the processing operation using the display and the speaker of the in-vehicle device as the output device of the mobile terminal is described assuming that the mobile phone owned by the vehicle driver is used as the mobile terminal. Even when the in-vehicle device is used as an external device, if the present invention is applied to the operation of the mobile phone terminal owned by the rear seat occupant of the vehicle, the display and the speaker of the mobile phone terminal itself may be used. Is preferred.

  As described above, the communication program and the mobile terminal device according to the present invention are useful for providing various services by the mobile terminal device linked with the external device, and in particular, the automatic operation of the appropriate operation according to the linkage status with the external device. Suitable for selection.
