For example, when the telephone number or the postal code is in the numeric input state, the number assigned by the cellular phone is input by operating the numeric key of the cellular phone 17.
[0069]
In other words, 1 is input when the 1 key of the mobile phone is operated, and 2 is input when 2 is operated. In the case of a 50-sound input state, a string of 50-sounds (“A, K, S, T, N, H, M, R, W, N, Symbol”) is assigned to the numeric keys of the mobile phone 17. An input that determines a line of 50 sounds depending on the number of operations, for example, if a key 1 (corresponding to that line) of a mobile phone is operated three times and a confirmation operation is performed, “U” is input. . Such an input method can be applied to various key operations of the mobile phone 17.
[0070]
Further, when the display unit of the screen displayed on the navigation device 1 display unit 14 is selected by the input unit 21 of the mobile phone 17, first the specific button of the mobile phone 17 is operated and then the cursor movement key is used. If a display button is selected and the operation (control) is set so that the direction is immediately indicated by the cursor movement key at the time of a direction instruction operation such as a map movement operation (destination setting), it is displayed on the map. Even when buttons are displayed (destination surrounding map display screen in FIG. 9), it is possible to selectively perform display button selection operation and map movement with the cursor movement key of the mobile phone 17. .
[0071]
When the navigation operation mode is switched, the display of the display unit 14 of the navigation device 1 has a character display “Now in the navigation operation mode by the mobile phone” or a mark indicating that, for example, a mark shaped like a mobile phone. It is displayed on the screen where it is easy to see. On the display unit of the mobile phone 17, a character display “Navi mode: call cannot be made” or a mark indicating that appears on the screen where it is easy to see.
[0072]
Also, when a call is received during the navigation operation mode, a message such as “I cannot talk now” is sent to the other party, and the other party's phone number, the other party's phone number, and the other party's voice The contents such as messages are stored in the memory.
[0073]
When the navigation operation state is released as described above, the mobile-side input unit 21 of the mobile phone 17 is switched to the call operation state for mobile phone operation. Accordingly, the character display “Now in navigation operation mode by mobile phone” displayed on the display screen of the display unit 14 of the navigation device 1 and the “Navi mode: call” displayed in the display scene of the mobile phone are displayed. The display of “Cannot make a call” is deleted. When a specific button (received call display button) of the navigation side input unit 11 is operated, the contents of the call that has been received during the stored navigation mode are displayed on the display screen of the mobile phone.
[0074]
In addition, just before this mode is canceled and the outgoing call operation state is switched from the navigation operation mode described above, “the navigation operation mode of the operation unit of the mobile phone is terminated” or “the outgoing call of the mobile phone becomes possible” Can be displayed on the screen of the mobile phone and voice guidance can be provided.
[0075]
Next, processing performed by the microcomputer that realizes such a navigation system 100 will be described.
[0076]
FIG. 10 is a process of switching to the navigation operation mode by the mobile phone 17 performed by the microcomputer 7 of the navigation apparatus 1 according to the present invention, and is repeatedly executed together with other processes during the operation of the navigation apparatus 1.
[0077]
In step S1, it is determined whether or not a specific operation state for shifting to the navigation operation mode has been detected. If the specific operation state is detected, the process proceeds to step S2. If not, the process proceeds to step S5. In step S2, a navigation mode switching signal is transmitted to the mobile phone 17, and the process proceeds to step S3. In step S3, a signal from the mobile phone 17 is received, and the mobile phone operable mode for performing control according to the operation signal is set, and the process proceeds to step S4. In step S4, a character display of “Navi operation mode is being set” or a “mobile phone symbol mark” or the like is displayed where it is easy to see on the screen of the display unit 14 of the navigation device 1, and the process ends.
[0078]
In step S5, it is determined whether or not there is an operation that should cancel the navigation operation mode. In step S6, a switching signal for canceling the navigation operation mode and setting the call operation mode is transmitted to the mobile phone 17, and the process proceeds to step S7. In step S7, the display indicating that it is the navigation operation mode is erased, and the character display of “end of navigation operation mode” is displayed for a certain period of time in a place where the screen of the display unit 14 is easy to see, and the process proceeds to step S8. In step S8, the portable operation enabling mode is canceled and the process is terminated.
[0079]
In this example, the navigation device 1 accepts the operation signal of the mobile phone 17 only in the navigation operation mode, but the navigation device 1 may be controlled to always accept the operation signal.
[0080]

In step T1, it is determined whether or not a navigation mode switching signal has been received from the navigation device 1, and if there is, the process proceeds to step T2, and if not, the process ends. In step T2, the navigation operation mode is switched to step T3. In step T3, the call function (transmission and telephone operation) is stopped and the process proceeds to step T4. In step T4, a character display of “In navigation operation mode: outgoing call cannot be made” or “symbol mark of mobile phone” is displayed in an easily visible place on the display unit of the mobile phone 17, and the process proceeds to step T5. In step T5, the operation content by the portable side input part 21 is input, and it moves to step T6. In Step T6, it is determined whether or not the input of the operation content in the navigation operation mode has been completed (operation for transmitting an operation signal to the navigation device 1). If there is, the process proceeds to Step T7, and if not, the process proceeds to Step T8. In step T7, the operation content is transmitted to the navigation device 1, and the process returns to step T5. In step T8, it is determined whether or not there is an operation for canceling a specific navigation operation mode, and if there is, the process proceeds to step T9, and if not, the process proceeds to step T12. In step T9, a cancellation signal indicating cancellation of the navigation operation mode is transmitted to the navigation apparatus 1, and the process proceeds to step T10. In step T10, the navigation operation mode is switched to the call operation mode, and the process proceeds to step T11. In step T11, all the operations / operations related to the mobile phone are resumed, and the process ends. In step T12, it is determined whether a navigation operation mode release signal from the navigation device 1 has been received. If it has been received, the process proceeds to step T10, and if not, the process proceeds to step T13. In step T13, it is determined whether or not a telephone call has been received.
