When driving the automobile, the user of the mobile phone 10 normally connects the mobile phone 10 to the in-vehicle device 30 via the connection unit 20 and turns on the setting of the driving mode by the driving mode setting means 16. And

Mobile phone 1 in standby state while driving
For 0 (step 41 in FIG. 2), assuming that the reception signal is received from the antenna 11 to the transmission / reception unit 12 and there is an incoming call (step 42 in FIG. 2), the control unit 14 turns on the operation mode setting. / Off is determined (step 4 in FIG. 2).
3). As described above, since the setting of the driving mode is ON while the user of the mobile phone 10 is driving, in this case, the control unit 14 determines whether or not there is a connection to the in-vehicle device 30 (step 44 in FIG. 2). . As described above, the mobile phone 10
Since the user is connected to the in-vehicle device 30 while driving, the control unit 14 receives the connection detection result from the in-vehicle device connection detection unit 18, and in this case, is prepared in advance.
An announcement (message) indicating that the vehicle is driving is transmitted to the caller via the transmitting / receiving unit 12 and the antenna 11 (step 45 in FIG. 2).

Subsequently, the control unit 14 determines whether or not the answering machine is set by the input means (not shown in FIG. 1) (step 46 in FIG. 2). Since the above-mentioned announcement also includes the content urging the sender to send a message, the message transmitted from the sender based on this is transmitted and received by the transmitting / receiving unit 12.
Is received, the message is recorded in the recording memory 17 (step 47 in FIG. 2), the communication is terminated (step 48 in FIG. 2), and the process returns to the standby state in step 41.

On the other hand, when the answering machine is set to OFF, the above-mentioned announcement does not include a content for prompting the caller to send a message, so that the communication is terminated (step 49 in FIG. 2) and step 41 Return to the standby state.

As described above, in this embodiment, the user of the mobile phone 10 can connect the connection unit 20 when driving the automobile.
The mobile phone 10 is connected to the in-vehicle device 30 via the, and the setting of the operation mode is turned on by the operation mode setting means 16, so that the vehicle stops during the low speed operation or at the red light as in the high speed operation. Even when there is, the other party can be notified that the vehicle is being driven and there is no incoming call, so that the possibility of a traffic accident can be greatly reduced as compared with the related art.

If the user of the mobile phone 10 forgets to connect the mobile phone 10 to the in-vehicle device 30 via the connection unit 20 when driving the automobile, or does not connect, the driving mode setting means can be used. If the setting of the operation mode has been turned on by the control unit 16, the control unit 14 compares the speed of the mobile phone 10 detected by the speed detection unit 15 with a preset threshold value (step 50 in FIG. 2). If the speed is higher than the threshold value, it is determined that the vehicle is moving together with the car, and a prepared announcement (message) indicating that the vehicle is driving is transmitted to the caller via the transmitting / receiving unit 12 and the antenna 11. Thereafter (step 45 in FIG. 2), the above-described processing of steps 46 to 48 or step 49 is performed, and the process returns to the standby state. If the speed is lower than the threshold value in step 50, the control section 14 sends a calling signal to the calling means 13 to start calling (step 51 in FIG. 2). By this call, the user knows that there is an incoming call to the mobile phone 10,

As a result, the possibility of a traffic accident can be significantly reduced as compared with the related art.

On the other hand, when the setting of the operation mode is turned off by the operation mode setting means 16, the control unit 14 compares the speed of the mobile phone 10 detected by the speed detection means 15 with a preset threshold value. A comparison is made (step 50 in FIG. 3). If the speed is higher than the threshold value, it is determined that the vehicle is moving together with the car, and a prepared announcement (message) indicating that the vehicle is driving is transmitted and received by the transmitting / receiving unit 12 and the antenna. 11 to the caller (step 4 in FIG. 3)
5), the above-described processing of steps 46 to 48 or step 49 is performed, and the process returns to the standby state.

If the speed is lower than the threshold value in step 50, the control section 14 sends a calling signal to the calling means 13 to start calling (step 51 in FIG. 3). By this call, the user knows that there is an incoming call to the mobile phone 10 and, for example, starts a hands-free call.

In this embodiment, the portable telephone 1
