Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a block diagram showing a schematic communication system of a car navigation device with a telephone function according to a first embodiment of the present invention, FIG. 2 is a block diagram showing a configuration of the car navigation device with a telephone function, FIG. 3 is a display screen diagram of an example of the car navigation device with a telephone function.

As shown in FIG. 1, a schematic communication system of a car navigation system with a telephone function according to the first embodiment has a telephone unit 5 built therein, and a navigation device body 6 mounted on an automobile, and a destination. (Telephone) 7 and V
An information providing source 8 such as an ICS center is provided, and a detection signal, that is, a control signal is applied to the navigation device main body 6 from a parking operation state detection unit 9 in the automobile.

Here, when the vehicle is stopped, the parking operation state detecting section 9 does not send a control signal to the navigation apparatus main body 6, and the navigation apparatus main body 6 operates normally, that is, the information providing source 8 More various information is collected, and a required navigation is displayed on the map screen of the display unit. The telephone unit 5 can make a general telephone call with the other party (telephone) 7.

Next, while the vehicle is running, the parking operation state detecting section 9 sends a control signal to the navigation apparatus main body 6 to control the telephone section 5 to be in a communication disabled state. That is, incoming calls are allowed, for example, handset 1
The transmission circuit of 0 is cut off to prevent transmission. Therefore, the driver does not operate the handset 10 during traveling, so that further safe driving of the automobile is ensured.

More specifically, as shown in FIG.
The navigation device body 6 includes a control unit 11, a telephone unit 5 with an answering machine function, a display unit 12 composed of an LCD, and an audio output unit 13 composed of a speaker. And
The control unit 11 receives a detection signal from the parking operation state detection unit 9, that is, a unit that identifies a stop or running state of the vehicle. Here, the parking operation state detecting unit 9 uses a switch of a parking brake lamp. The control unit 11 further includes a telephone unit 5, a display unit 12, an audio output unit 13, and a handset 1
0 is controlled to operate.

In the above configuration, when the vehicle is stopped, the parking operation state detecting section 9 turns off its lighting switch to GND, does not send a control signal to the navigation apparatus body 6, and the navigation apparatus body 6 performs a normal navigation operation. And the handset 10 can be used.

Next, while the vehicle is running, the parking operation state detecting section 9 disconnects the lighting switch from GND, sends a control signal to the navigation apparatus main body 6, and the navigation apparatus main body 6 performs road guidance and map display. ,
A menu operation such as a search cannot be performed, that is, a menu screen is not displayed on the display unit 12, and a circuit to the handset 10 is cut off to make a general call impossible.

Here, the telephone unit 5 having the answering machine function is switched to the answering machine function, and when there is an incoming call, the telephone information is recorded in the recording device, and the telephone information can be reproduced and heard later.

In the above-described embodiment, the answering machine function is used because a telephone call cannot be made during traveling. However, the incoming call is separately monitored by the control unit 11 and character display is performed in real time, that is, at the time of incoming call. Is displayed on the display unit 12 as shown in FIG. 3A, a message is displayed as shown in FIG. 3B, and a list is displayed as shown in FIG.
It is possible to notify the driver of telephone information while driving or stopping.

The telephone section 5 may have a small portable telephone function, that is, a pager function, in addition to the answering machine function. In this configuration, the control unit 11 switches the telephone unit 5 to the pager function while the vehicle is running, and when there is an incoming call, the message is displayed on the display unit 12 to notify the driver of the telephone information. it can.

As another means, while the vehicle is running, the control unit 11 controls the display unit 12 which is the output side to be in an inactive state and controls only the voice output unit 13 to be in an active state, so that the incoming telephone signal is transmitted by voice. The information may be transmitted only to the output unit 13 to notify the driver of the telephone information by voice only.

The telephone section 5 may have an automatic answering function in addition to the answering machine function and the pager function. In this configuration, the control unit 11 controls the telephone unit 5 while the vehicle is running.
Is switched to an automatic answering function, and when there is an incoming call, for example, "I am traveling and will call later" is automatically answered.

Further, the telephone unit 5 may have an automatic transfer function other than the above. In this configuration, the control unit 11 switches the telephone unit 5 to the automatic transfer function while the vehicle is running, and when there is an incoming call, the other party's telephone is transferred from the telephone unit 5 to another required telephone.

As described above, the car navigation apparatus with a telephone function according to the present embodiment does not carry out a call operation while holding a handset or the like while the automobile is running, and when a telephone call is received while the automobile is running, the operation is stopped. Incoming telephone information can be recorded, displayed on a display unit, or by voice, and can be notified to the driver and responded to the other party by automatic response, automatic transfer, and the like.

[0030]

As is apparent from the above description, the present invention automatically controls the telephone unit so that the telephone cannot be talked while the vehicle is running. There is no safe driving. Since calls cannot be made, when a call is received while driving, the incoming call information is recorded, displayed on the display unit, or informed by voice, and furthermore, the driver is notified and the other party is notified by automatic answer, automatic transfer, etc. And a highly convenient car navigation device with a telephone function can be provided, and the effect is great.
