In the remote control BT connection state, the program 400 is executed.

  Here, consider a case where three mobile phones having the same configuration and operation as the mobile phone 2 are carried in a vehicle in which the vehicle navigation device 1 is mounted. Of these three mobile phones, one (hereinafter referred to as mobile phone 2a) is owned by a driver who normally operates the vehicle, and the other two (hereinafter referred to as mobile phone 2b and mobile phone 2c). Is assumed to be owned by a person who does not drive the vehicle. The mobile phone 2a is registered for hands-free registration and remote control in the vehicle navigation device 1, and the mobile phone 2b is neither registered for hands-free registration nor remote control in the vehicle navigation device 1, and the mobile phone 2c Assume that only remote control registration is performed in the vehicle navigation apparatus 1.

  Here, the hands-free registration of the mobile phone is to record identification information of the mobile phone as a device connectable for the hands-free call function in the storage medium of the external storage unit 18 of the vehicle navigation apparatus 1. Say. Specific methods for recording the identification information include a method of recording based on an input operation for inputting user identification information to the operation switch group 12 of the vehicle navigation device 1, and a portable device within the communicable range of the Bluetooth device 10. The identification information transmitted from the telephone is acquired, the acquired identification information is displayed in a list on the image display device 13, a selection operation using the user operation switch group 12 is accepted, and the selected identification information is displayed. There is a way to record.

  Also, the remote control registration of the mobile phone means that the identification information of the mobile phone is recorded in the storage medium of the external storage unit 18 of the vehicle navigation device 1 as a device that can be connected for the remote operation function. The specific method of recording the identification information is a method of recording based on an input operation for inputting user identification information to the operation switch group 12 of the vehicle navigation apparatus 1 as in the hands-free registration, or the current Bluetooth device 10. Acquires identification information transmitted from a mobile phone within a communicable range, displays the acquired identification information in a list on the image display device 13, accepts a selection operation using the user operation switch group 12 for the identification information, and selects There is a method for recording the identification information.

  Here, the user of the mobile phone 2a who is not in Bluetooth connection with the vehicle navigation apparatus 1 starts a remote operation function using the mobile phone 2a for the input key group 22 of the mobile phone 2. Assume that a predetermined operation is performed. This predetermined operation is called a remote control mode setting operation. In the idle state, the control circuit 29 waits until the remote control mode setting operation is performed in step 310, and when the remote control mode setting operation is performed, subsequently, in step 320, the vehicle navigation device 1 is used using the Bluetooth device 20. In response, a remote control Bluetooth connection request is transmitted. The remote control Bluetooth connection request includes the same identification information of the mobile phone 2a as that used in the above-mentioned hands-free registration and remote control registration.

  On the other hand, in the idle state, the control circuit 19 of the vehicle navigation apparatus 1 waits until the Bluetooth device 10 receives a remote control Bluetooth connection request from the mobile phone in step 110 of the program 100 and receives the remote control Bluetooth connection request. Subsequently, in step 120, it is determined whether or not the mobile phone is registered as hands-free by comparing the received identification information in the remote control Bluetooth connection request with the identification information registered as hands-free, If the hands-free registration has not been made, step 120 is subsequently executed. Here, since the cellular phone 2a is registered as hands-free, the control circuit 19 determines that it is registered as hands-free in step 120. Thereafter, in step 115, a connection rejection signal is carried using the Bluetooth device 10. A reply is made to the telephone 2a, and then step 110 is executed again.

  After transmitting the remote control BT connection request signal in step 320, the control circuit 29 of the cellular phone 2a waits for a reply from the vehicle navigation apparatus 1 in step 330, and from the vehicle navigation apparatus 1 based on the reply. It is determined whether or not the connection is rejected. Specifically, if the reply is a connection rejection signal, it is determined that the connection has been rejected, and if it is a connection permission signal, it is determined that the connection has not been rejected. In this case, when the connection rejection signal is received from the vehicle navigation device 1, the process returns to step 310.

  Due to the operation of the vehicle navigation device 1 and the mobile phone 2a, the mobile phone 2a is registered as a hands-free device. Therefore, the Bluetooth connection for functioning as a remote device of the vehicle navigation device 1 is used. Prohibited by device 1.

  Next, it is assumed that the user of the mobile phone 2b who is not in the Bluetooth connection with the vehicle navigation apparatus 1 performs a remote control mode setting operation on the input key group 22 of the mobile phone 2. At this time, as in the case of the mobile phone 2a, the control circuit 19 determines in step 310 that there has been a remote control mode setting operation, and then in step 320, the control circuit 19 uses the Bluetooth device 20 to switch to the vehicle navigation apparatus 1. In response, a Bluetooth connection request for remote control is transmitted.

  Then, the control circuit 19 of the vehicle navigation device 1 determines in step 110 that the remote control Bluetooth connection request has been received, and subsequently determines in step 120 whether or not the mobile phone is registered as a hands-free device. To do. Since the mobile phone 2b is not registered as a hands-free device, the control circuit 19 subsequently determines in step 125 whether or not the mobile phone is registered as a remote controller, the received identification information in the remote control Bluetooth connection request, and the remote controller. Judgment is made by comparing the registered identification information. Since the mobile phone 2b is not registered with the remote controller, the control circuit 19 determines that the remote controller is not registered in step 125, and then returns a connection rejection signal to the mobile phone 2b using the Bluetooth device 10 in step 115. Then, step 110 is executed again.

  Then, the control circuit 29 receives the connection refusal signal from the vehicle navigation device 1 and then returns to step 310.

  Due to the operation of the vehicle navigation device 1 and the mobile phone 2b, the mobile phone 2b is not registered as a remote control. Therefore, the Bluetooth connection for functioning as a remote device of the vehicle navigation device 1 is used. Forbidden by 1.

  Next, it is assumed that the user of the mobile phone 2c that is not in a Bluetooth connection with the vehicle navigation apparatus 1 performs a remote control mode setting operation on the input key group 22 of the mobile phone 2. At this time, as in the case of the mobile phone 2a, the control circuit 29 determines in step 310 that there has been a remote control mode setting operation, and then in step 320, the control circuit 29 uses the Bluetooth device 20 to switch to the vehicle navigation apparatus 1. In response, a Bluetooth connection request for remote control is transmitted.

  Then, the control circuit 19 of the vehicle navigation device 1 determines in step 110 that the remote control Bluetooth connection request is received, and subsequently determines in step 120 that the mobile phone is not registered as a hands-free device. In step 125, it is determined whether or not the mobile phone is registered as a remote control. Since the mobile phone 2c is registered as a remote controller, the control circuit 19 determines that the remote controller is registered. Subsequently, at step 130, a connection permission signal is transmitted to the mobile phone 2c, and the mobile phone 2c is connected to the mobile phone 2c via Bluetooth connection. Send and receive data for. In step 330, the control circuit 29 determines that the connection has not been rejected by receiving the connection permission signal. Subsequently, in step 360, the control circuit 29 exchanges data for connecting the vehicle navigation apparatus 1 and the remote control BT. I do.

  When the remote control BT connection is established between the vehicular navigation device 1 and the mobile phone 2c as a result of the remote control BT connection processing in steps 130 and 360, the control circuit 29 of the mobile phone 2 in step 370 displays the image display device. 23 is displayed to indicate that the connection is complete, and then in step 380, the state of itself is shifted to the remote control BT connection state, thereby ending the execution of the program 300 and starting the execution of the program 400. Further, after establishing the remote control BT connection, the control circuit 19 of the vehicle navigation apparatus 1 subsequently transitions its own state to the remote control BT connection state in step 140, thereby terminating the execution of the program 100. 200 execution is started.

  In the Bluetooth connection state, the control circuit 19 of the vehicle navigation device 1 first requests the remote control BT connection in step 210 from a mobile phone other than the mobile phone 2 to which the Bluetooth device 10 is currently connected to the remote control BT. If it has been received, step 220 is executed. If it has not been received, step 230 is executed. In step 220, a connection rejection signal is transmitted to the mobile phone that has transmitted the remote control BT connection request, and then step 230 is executed.

  In step 230, it is determined whether or not a remote control command (corresponding to a remote operation command) has been received from the mobile phone 2 (hereinafter referred to as the counterpart mobile phone 2) connected to the remote control Bluetooth. If so, step 250 is executed, and if received, then in step 240, processing corresponding to the received remote control command is executed, and then step 250 is executed. Here, as will be described later, the remote control command is a command for remotely operating the vehicle navigation device 1 based on the user's operation on the counterpart mobile phone 2, and the operation requested to the vehicle navigation device 1 is requested. Contains content. Here, examples of processing according to the remote control command include enlargement, reduction, scrolling of the display screen, destination input for route search for guidance route calculation, screen switching, and the like.

  In step 250, it is determined whether or not the Bluetooth device 10 has received a Bluetooth disconnection request from the counterpart mobile phone 2. If received, step 260 is executed. If not, step 250 is executed. Execute.

  By executing the steps 210 to 260, the control circuit 19 can receive a remote control BT connection request from another mobile phone until receiving a Bluetooth disconnection request in the Bluetooth connection state (see step 250). The connection request is rejected (see steps 210 and 220), and when a remote control command received from the counterpart mobile phone 2 is received, an operation designated by the received remote control command is executed (see steps 230 and 240).

  Further, in step 260, the control circuit 19 performs a process of disconnecting the Bluetooth connection with the counterpart mobile phone 2, and then in step 270, changes its own state to the idle connection state, thereby executing the program 200. End and start execution of the program 100.

When the control circuit 19 executes the program 100 and the program 200 as described above, the vehicular navigation apparatus 1 receives the remote control BT connection request from the mobile phone 2 (see step 110), and the mobile phone 2 is handled. Only when the mobile phone 2 is not a free-registered mobile phone (see step 120) and the mobile phone 2 is a remote-registered mobile phone (see step 125), the remote control BT connection with the mobile phone 2 is permitted. Then, based on the reception of the remote control command from the mobile phone 2, the operation designated by the received remote operation command is executed (see steps 230 and 240). Here, the fact that the mobile phone 2 is registered as hands-free means that it is highly likely that the owner of the mobile phone 2 is a person who frequently drives a vehicle equipped with the vehicle navigation device 1. Therefore, there is a high possibility that the mobile phone 2 is a mobile phone owned by the current driver. Accordingly, the vehicular navigation device 1 checks whether the mobile phone is owned by the driver by checking the identification information of the mobile phone registered hands-free with the identification information in the remote control BT connection request. Only when it is determined whether or not it is not owned by the driver, the operation of accepting a remote operation command from the mobile phone is substantially performed. In this way, the vehicle navigation device 1 can limit the act of the driver operating the vehicle navigation device 1 using the mobile phone while driving.

  Further, the vehicle navigation apparatus 1 accepts a remote operation command only from the partner mobile phone 2 that has established the remote control BT connection (see steps 230 and 240), and during that time, the remote control BT from another mobile phone is received. The connection request is rejected (see steps 210 and 220). That is, the vehicle navigation apparatus 1 accepts a remote control command from the requesting mobile phone in response to the remote control BT connection request only when the remote control BT connection is not established with another mobile phone. In this case, for the mobile phone 2 that transmits the remote control BT connection request, the remote operation command reception period of the other mobile phone is long while the vehicular navigation device 1 is performing the remote control BT connection with the other mobile phone. It can be said that it is inside.

  As described above, the vehicle navigation apparatus 1 accepts a remote control command from the mobile phone 2 only when it is not during a period for accepting a remote operation command by another mobile phone, thereby at least one mobile phone 2 at a time. It is possible to perform an operation that only accepts remote operation from the remote control.

  Further, the control circuit 29 of the mobile phone 2 determines whether or not there is a remote control key input in step 405 when executing the program 400 in the Bluetooth connection state. The remote control key input is a key assigned for remote operation in the input key group 22. If there is no remote key input, step 415 is subsequently executed. When there is a remote control key input, in step 410, a remote control command including an operation request corresponding to the key is transmitted to the vehicle navigation apparatus 1 via the Bluetooth device 20, and then step 415 is executed.

  In step 415, it is determined whether or not there is an operation of a key assigned as a Bluetooth connection end key in the input key group 22, and if there is an operation, then step 420 is executed. Subsequently, step 430 is executed.

  In step 420, the Bluetooth connection with the vehicle navigation device 1 is disconnected, and then in step 425, the state of the program 200 is ended and the execution of the program 100 is started by transitioning to the idle connection state. .

  In step 430, it is determined whether or not the reference time has elapsed since the last time the input key group 22 was operated. If so, step 420 is executed. If not, the operation continues. Step 435 is executed. The reference time may be a constant value stored in advance, a value that varies based on various conditions, or a value that is randomly determined within a certain range.

  In step 435, it is determined whether or not an e-mail has been received via the telephone wireless communication circuit 21. If there is no incoming e-mail, then step 445 is executed, and if there is an incoming call, the Bluetooth connection is disconnected. Otherwise, in step 440, the mail is received, and then step 450 is executed.

  In step 445, it is determined whether or not there is an incoming call via the telephone wireless communication circuit 21, and if there is no incoming call, then step 405 is executed, and if there is an incoming call, then step 445 is executed. .

  In step 450 after receiving a telephone call, it is determined whether or not a call key is operated. If there is an operation, step 460 is subsequently executed, and if not, step 455 is subsequently executed. In step 455, it is determined whether or not the incoming call has been interrupted because the other party has interrupted the call. If there is an incoming call interruption or no incoming call interruption, step 460 is executed.

  Subsequently, in step 460, the Bluetooth connection is disconnected by the same operation as in step 420, and then in step 470, the above-described telephone call processing is executed. After the telephone call process is completed, the execution of the program 400 is ended and the execution of the program 300 is started in step 480 by changing its own state to the idle connection state.

  When the control circuit 29 executes the program programs 300 and 400 as described above, the mobile phone 2 accepts a remote control mode setting operation (see step 310), and sends a remote control BT connection request to the vehicle navigation apparatus 1. By transmitting (see step 320) and receiving connection permission from the vehicle navigation device 1 (see step 330), the state shifts to the remote control BT connection state with the vehicle navigation device 1 (see steps 360 to 380). The mobile phone 2 remotely controls the vehicle navigation device 1 by transmitting a remote control command based on the operation of the remote control key by the user to the vehicle navigation device 1 in the BT connection state for the remote control (steps 405 and 410). reference).

  Further, the mobile phone 2 establishes the Bluetooth connection when the user inputs a key for ending Bluetooth connection (see step 415) or when the operation of the input key group 22 is not continued for a reference time or longer (see step 430). Disconnect. As a result, another mobile phone 2 can remotely control the vehicle navigation device 1. Since it can be said that there is a key input for terminating Bluetooth connection and that the operation of the input key group 22 is not continued for a reference time or more, this is a break in a series of remote control operations by the user. Based on the detection of a break between a series of remote control operations performed by the user, the remote operation period of the vehicle navigation device 1 (remote command reception period when viewed from the vehicle navigation device 1) can be terminated.

  Further, when there is an incoming call (see step 445), the cellular phone 2 waits for an operation of the call key (see step 450) until the incoming call is cut off (see step 455). Is disconnected (see step 470) and telephone call processing is performed (see abandoned woman 480).

  In this way, while the mobile phone 2 that has been connected to the remote control BT makes a telephone call, the other mobile phone 2 performs the remote control BT connection to remotely control the vehicle navigation device 1. Will be able to.

  In the above embodiment, the vehicle navigation device 1 corresponds to a vehicle-mounted receiving device, and the BT device 10 corresponds to a receiving circuit. The BT device 20 corresponds to an interface for establishing a Bluetooth wireless connection with the in-vehicle receiving device, and the input key group 22 corresponds to an input device. The programs 100 and 200 correspond to the in-vehicle receiving device program, and the program 300 and the program 400 correspond to the mobile phone program.

  Further, the control circuit 19 functions as a non-registration detection unit by executing step 120 of the program 100, and functions as a remote operation command handling unit by executing steps 230 and 240 of the program 200. Further, the control circuit 19 executes steps 210, 220, 250, 260, and 270 of the program 100 and the program 200, thereby functioning as a connection unit. Further, the control circuit 19 performs hands-free processing to function as a hands-free call means.

Further, the control circuit 29 functions as a connection establishment unit by executing the program 300, and functions as a remote operation command transmission unit by executing steps 405 and 410 of the program 400, and executes step 460. Thus, it functions as a cutting means.

That is, when the vehicle navigation device 1 receives a remote control Bluetooth connection request from the mobile phone 2, the mobile phone 2 is not a hands-free registered mobile phone, regardless of whether the remote control is registered or not. A Bluetooth connection for remote control with the mobile phone 2 may be permitted.

  In addition, the control circuit 29 of the mobile phone 2 transmits the Bluetooth connection request for the remote control again until the connection reject signal is continuously received for the reference number of times (for example, three times) or more in the determination in step 330 of the program 300. When the connection rejection signal is continuously received as described above, it may be determined that the connection is rejected for the first time.

  In addition, it is necessary to detect whether or not the mobile phone that is the source of the Bluetooth connection request for remote control is owned by the driver by determining whether or not the mobile phone has been hands-free registered. For example, if the storage medium of the external storage unit 18 records the identification number of a mobile phone owned by a person who frequently drives the vehicle mounted on the vehicle navigation device 1, the identification is performed. You may detect by collating a number with the identification information in the Bluetooth connection request | requirement for remote control.

  Further, when receiving an incoming call in the Bluetooth connection state, the control circuit 29 may disconnect the BT connection for remote control before receiving the call key input.

  In addition, the control circuit 29 may execute the program 300 from step 320 in the process of transitioning to the idle state after the telephone call process is completed in step 480 of the program 400. In this way, the cellular phone 2 attempts to automatically recover the Bluetooth connection for remote operation that is disconnected by the incoming call after the call ends.

  Further, the control circuit 19 may disconnect the Bluetooth connection with the mobile phone 2 when the remote control command is not received from the counterpart mobile phone 2 for a reference time or longer in the Bluetooth connection state.

  Further, the identification information (corresponding to the registered mobile phone information) recorded in the hands-free registration and the remote control registration and the identification information included in the remote control Bluetooth connection request transmitted in step 320 of the program 300 may not be the same. It is enough if you can understand that they correspond to each other.
