Hereinafter, each of the commands C _{1 to} C ₅ will be described.
First, the command C ₁ will be described. When transmitting the command C ₁ to the in-vehicle device 1, the user is assigned the numeric key 30 to which the characters constituting the character string “CDPLAY” are assigned, that is, the character “C” as shown in FIG. "2" number key 302, "D" character assigned "3" number key 303, "P" character assigned "7" number key 307, "L" character assigned The number key 305 of “5”, the number key 302 of “2” to which the character “A” is assigned, and the number key 309 of “9” to which the character “Y” is assigned are sequentially set in the number input mode. By pressing each time, the command C ₁ can be input.

On the other hand, the vehicle-mounted device 1 receives the numeric six-digit number string "237529" corresponding to the input order of the key 302,303,307,305,302,309 as a command C _1. In the command table 20, the operation target to be selected, that is, “select CD playback unit” is associated with the upper two digits “23 (CD)” in the number string constituting the command C _1. The lower four-digit number “7529 (PLAY)” is associated with a specific operation content in the operation target, that is, “CD playback”. When the in-vehicle device 1 receives this command C ₁ , the control unit 10 controls based on the command table 20 to shift the operation mode to the CD reproduction mode and cause the CD reproduction unit 11 to reproduce the CD.

You can enter. Then, the in-vehicle device 1 receives a six-digit numeric string “261629” corresponding to the input order of the numeric keys 30 by the user as the command C ₂ . When the in-vehicle device 1 receives this command C ₂ , the control unit 10, based on the command table 20, operates the operation target associated with the first two digits “26 (AM)” of the command C ₂ , that is, “radio”. “AM tuner in receiving unit” is selected, and control is performed so that the radio receiving unit 13 receives an AM radio broadcast wave of 1629 kHz according to the operation content “receive 1629 kHz” associated with the lower four-digit number “1629”. .

Similarly, if the command C _3, the user by pressing by sequentially once a numeric key 303,306,300,309,308,301 the letter or number is assigned constituting the "FM0981" command C ₃ , you can enter the command C _3. The in-vehicle device 1 receives a six-digit numeric string “360981” corresponding to the input order of the numeric keys 300 to 309 by the user as the command C ₃ . Then, when the in-vehicle device 1 receives this command C ₃ , the control unit 10 selects the FM tuner in the radio reception unit 13 as an operation target based on the command table 20, and the radio reception unit 13 selects specific operation contents. Control to receive 98.1 MHz FM radio broadcast radio waves.

On the other hand, in the case of the command C ₄ , the user does not specify the frequency of the radio broadcast radio wave to be received by the radio receiving unit 13, but the vehicle-mounted device 1 receives the frequency assigned to the channel number 01 as the preset channel. Can be directed. This command C ₄ is “FMCH01 (FM channel number CH01)”. Similarly to the above, the user can use the numeric keys 303, 306, 302, 304, to which the letters or numbers constituting “FMCH01” are assigned. The command C ₄ can be input by pressing 300 and 301 once in order. The in-vehicle device 1 receives a six-digit numeric string “362401” corresponding to the input order of the numeric keys 30 by the user as the command C ₄ , and receives an AM radio broadcast wave having a frequency assigned to the channel number CH01 of the preset channel. The radio receiving unit 13 is controlled to receive.

In the present embodiment, the user can assign the frequency of the radio broadcast radio wave currently being received to the desired channel number as the preset channel. In this case, as in commands C ₅ and C ₆ , the user indicates ME (63) indicating MEMORY (memory, registration), CH (24) indicating a channel, and channel number (for example, 01, By transmitting a command indicating registration of the preset channel configured in (02) to the in-vehicle device 1, it is possible to assign a predetermined frequency to the designated channel number as the preset channel.

Next, the operation of the in-vehicle device 1 when the remote operation of the in-vehicle device 1 is performed by the mobile phone 3 will be described with reference to FIG. The operation shown in FIG. 5 is executed under the control of the control unit 10.
First, at the start of remote operation by the mobile phone 3, various settings for performing short-range wireless communication between the in-vehicle device 1 and the mobile phone 3 are performed, and the short distance between the in-vehicle device 1 and the mobile phone 3 is set. Wireless communication is started (step S1). Here, when short-range wireless communication is performed between the in-vehicle device 1 and the mobile phone 3 by Bluetooth (registered trademark), in step S1, verification of Bluetooth identification information (ID) assigned to each device is performed. Matching between models is performed.

  Next, the in-vehicle device 1 waits for reception of a command from the mobile phone 3 (step S2), and when the control unit 10 determines that the command has been received (step S2: Y), the control unit 10 refers to the command table 20. Then, it is determined whether or not there is a command whose upper two digits match among the commands included in the command table 20 (step S3).

  If a command that matches the first two digits of the received command is included in the command table 20 (step S3: Y), then the first two digits are “63 (ME, preset channel registration)”. It is discriminate | determined (step S4).

  If the first two digits are not “63” (step S4: N), an operation target corresponding to the first two digits is selected based on the command table 20, and an operation mode is determined (step S5). For example, as shown in FIG. 4, when the first two digits of the received command are “23”, the CD playback unit 11 is selected as an operation target, and the control unit 10 plays the operation mode of the in-vehicle device 1 as a CD. Control to be in mode. Similarly, when the first two digits of the received command is “26”, the control unit 10 selects the AM tuner of the radio reception unit 13 as an operation target, and the first two digits of the command is “36”. ", The FM tuner is selected as the operation target, and when the first two digits are" 38 (DV) ", the DVD playback unit 12 is selected as the operation target, and the first two digits are" 68 (NV) ". ", The navigation unit 14 is selected as an operation target.

  Next, it is determined whether or not the command in which the lower four digits of the received command match is included in the command table 20 among the commands in which the upper two digits match (step S6). When a command with a matching number is included in the command table 20 (step S6: Y), the control unit 10 performs a predetermined operation control according to the operation content corresponding to the lower four digits (step S7).

  On the other hand, when it is determined that the first two digits of the received command are “63” (step S4: Y), the control unit 10 then determines whether or not a radio broadcast is currently being received (step S8). If it is determined that the radio broadcast is being received (step S8: Y), it is determined whether or not a channel number is designated by the lower four digits of the received command (step S9). Here, whether or not a channel number is specified is determined by whether or not the last four digits of the command start with “24 (CH)”.

  If a channel number is designated (step S9: Y), the command table 20 is rewritten by assigning the frequency of the currently received radio broadcast wave to the designated channel number (step S10). Then, the above process is repeatedly executed until the short-range wireless communication between the in-vehicle device 1 and the mobile phone 3 is completed (step S11: Y). However, if a correct command cannot be received in the above processing (step S3: N, step S6: N, step S8: N, step S9: N), short-range wireless communication between the in-vehicle device 1 and the mobile phone 3 is performed. As long as it has not ended (step S11: N), it waits for reception of a command again (step S2), and repeats the above processing.

  According to the present embodiment described above, when the in-vehicle device 1 receives a command from the mobile phone 3 via the short-range wireless communication unit 15, the control unit 10 stores the command table 20 stored in the table storage unit 19. Based on this, as shown in step S7, control is performed so as to perform an operation corresponding to the operation content instructed by the received command. The mobile phone 3 that transmits a command has a numeric key 30 (300 to 309) to which a different number among 0 to 9 can be input and to which a character is assigned, that is, a so-called numeric keypad. Any device capable of performing short-range wireless communication between devices such as Bluetooth (registered trademark) and IrDA may be used, so that a command is transmitted to the in-vehicle device 1 using a general-purpose mobile phone 3 having these configurations. 1 can be operated remotely.

  Further, in the present embodiment, the command is composed of a data string representing the input order of the numeric keys 300 to 309 by the user, that is, a six-digit numeric string, and any character assigned to the numeric keys 300 to 309 or When numbers are arranged and expressed in the order of input of the number keys 300 to 309 used when inputting the command, a character string representing a predetermined instruction operation content for the in-vehicle device 1 or a combination of a character string and a number string is obtained. Therefore, the user inputs a command according to the characters or numbers assigned to the number keys 300 to 309 so as to be a character string representing a predetermined instruction operation content or a combination of a character string and a number string. , You can easily remember commands, enter them easily, and have high operability.

  That is, in the present embodiment, a command as a predetermined character string or a combination of a character string and a number string is input in the number input mode without using the character input mode. For this reason, when a plurality of characters are assigned to the respective numeric keys 300 to 309 as in the mobile phone 3 of the present embodiment, the predetermined numeric keys 300 to 309 are used to input a predetermined character. Since there is no need to perform troublesome operations such as pressing several times in succession, the user can easily input commands and the operability is high.

However, the present invention is not limited to the embodiment described above, and it is needless to say that the present invention can be changed as appropriate without departing from the spirit of the present invention.
For example, in the present embodiment, a mobile phone has been described as an example of the portable electronic device used to remotely control the in-vehicle device 1, but the present invention is not limited to this, and for example, a PDA ( A portable electronic device such as Persona Digital Assistance, which has a numeric input key (including a software key) and is capable of short-range wireless communication such as Bluetooth (registered trademark) and IrDA with the in-vehicle device 1 As long as it is a thing, of course, you may enable it to remotely control the vehicle-mounted apparatus 1 similarly using those portable electronic devices.

  Further, the command table 20 shown in FIG. 4 is an example, and it is needless to say that the command is not limited to the numeric string shown in FIG. In addition, since characters assigned to the numeric keys 30 (300 to 309) of the mobile phone 3 may differ depending on the model or the like, a plurality of characters are stored in advance when the command table 20 is stored in the table storage unit 19 in the in-vehicle device 1. A command table 20 is prepared for each model, and when short-distance wireless communication with the mobile phone 3 is started, model information is acquired from the mobile phone 3 and the command table 20 corresponding to the model of the mobile phone 3 is acquired. Of course, operation control may be performed based on the above.

  In the above-described embodiment, the case where the command and the operation content designated by the command have a one-to-one relationship has been described in the command table 20, but one operation for a plurality of commands in the command table 20 is described. The contents may be associated with each other. For example, a numerical string “237636 (CDRNDM)” and “237435 (CDSHFL)” corresponding to a plurality of character strings “CDRNDM (CD RANDOM)”, “CDSHFL (CD SHUFLE)”, etc. reminiscent of random reproduction of a CD are used as commands. The “random playback of CD” is associated with each command in the command table 20, and the in-vehicle device 1 may perform random playback of the CD regardless of which command is input. In this way, if a command corresponding to a plurality of character strings or the like is prepared for a predetermined operation content, the user only has to input a command corresponding to a character string that is easy to remember. .

In the above embodiment, as a general rule, selection of an operation target, that is, specification of an operation mode and specific operation content are associated with one command. However, the present invention is not limited to this. Is not to be done. For example, when the operation target is not changed, only the specific operation content may be instructed to the in-vehicle device 1. That is, when the CD playback unit 11 has already been selected as an operation target and it is desired to instruct playback of the next song, the command C “CDNEXT (237738)” is sent via the mobile phone 3 as shown in FIG. Instead of transmitting ₇ to the in-vehicle device 1, only “NEXT (7738)” may be transmitted.

  In this embodiment, the command is described as being input in the numeric input mode, but the present invention is not limited to this. On the in-vehicle device 1 side, a data string indicating the input order of the numeric keys 300 to 309 used when inputting the command is managed as a command, and any character assigned to the numeric keys 300 to 309 is managed on the user side. Alternatively, when numbers are arranged and written in the order of input, a character string representing a predetermined operation content instructed to the in-vehicle device 1 or a combination of a character string and a number string may be used.

  In the present embodiment, the character string representing the predetermined operation content has been described as a character string made up of English characters. However, the present invention is not limited to this, and a character string made up of kana characters may be used. Of course, it may be a character string including kana characters and English characters.

  Of course, the radio receiving unit 13 may be configured to receive not only AM radio broadcast waves or FM radio broadcast waves but also short wave broadcasts, and the operation mode of the in-vehicle device 1 is the above embodiment. For example, an MD playback unit that plays back MD (Mini Disc (registered trademark)) or the like may be provided, and an MD playback mode may be used as an operation mode. is there.

  In addition, as shown in FIG. 1, a call is made to the mobile phone 3 from the fixed phone 5 or another mobile phone, and the command is transmitted to the mobile phone 3 via the short-range wireless communication network via the fixed phone 5 or the like. Of course, the in-vehicle device 1 may be remotely operated. According to this embodiment, if the mobile phone 3 is arranged at a distance capable of short-range wireless communication with the in-vehicle device 1, even if the user is outside the range capable of short-range wireless communication, the fixed phone 5 or the like is used. The vehicle-mounted device 1 can be remotely operated.
