However, the above conventional example has the following disadvantages. That is, when an incoming call arrives at the mobile phone while driving, the driver takes his / her line of sight out of the front view of the car in order to take out the mobile phone. Was.

[0005] In addition, when a user talks while holding a mobile phone while driving, other driving operations are hindered. In addition, even with a system in which a microphone or the like is provided on the vehicle body, the driver's hands are free, but since the driver's consciousness concentrates on the call, the driver's attention is distracted, and There has been an inconvenience that it is not possible to respond quickly to changes in the situation ahead.

[0006] In addition, when there is an incoming call to the mobile phone,
If the driver does not perform any operation, there is an inconvenience that the message of the caller is not transmitted to the driver.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automobile portable telephone system which can solve the disadvantages of the prior art and, in particular, can restrict the use of a portable telephone while driving and can surely communicate the requirements.

On the other hand, when the car stops, the call signal recorded in the call signal recording means can be output. Therefore, when the driver operates the call signal output means, the call signal can be appropriately heard later.

According to the third aspect of the present invention, when the mobile phone system detects from the output of the running state detecting means that the car is running, the predetermined incoming call answering means outputs an unanswerable signal to the incoming call. With a configuration that includes
Other configurations are the same as those of the first or second aspect. With the above-described configuration, when an incoming call is received while the automobile is running, the call signal recording unit records the call signal, and the incoming call response unit transmits an unresponsive signal to the base station. . This allows the caller to divert that the recipient will not be able to answer the mobile phone.

According to a fourth aspect of the present invention, the portable telephone system comprises a predetermined portable telephone body and a transmitting / receiving unit provided with a predetermined transmitting / receiving device, and the communication signal recording means and the communication signal output means are included in the transmitting / receiving unit.

[0012]

An embodiment of the present invention will be described with reference to the drawings.

In the automobile portable telephone system 1 according to the present invention, traveling state detecting means 3 for detecting the traveling state of the automobile.
A call signal recording means 5 for storing a call signal received based on an output of the traveling state detecting means 3; and a call signal output for outputting information of the call signal recording means 5 based on an output of the traveling state detecting means 3. Means 7 are provided. This will be described in detail below.

The mobile phone body 9 transmits and receives a call signal to and from a predetermined base station (not shown), and a predetermined telephone battery (not shown) provided in the mobile phone body 9. Driven by The telephone battery is rechargeable, and a telephone terminal (not shown) for charging is provided on the surface of the mobile phone body 9.

The mobile phone body 9 is held by a predetermined holder 11 installed in the vehicle while the vehicle is running. The holder 11 has a function of supplying charging power to a telephone battery of the mobile phone main body 9 in addition to a function of holding the mobile phone main body 9. Therefore, the holder 11 is also provided with a holder-side terminal (not shown) for charging. The holder-side terminal is positioned so as to come into contact with the telephone-side terminal when the mobile phone main body 9 is held by the holder 11. Note that the holder 11 is installed on a dashboard or instrument panel in an automobile (see FIGS. 2 and 3).

The holder 11 is supplied with electric power from a vehicle battery 13 mounted on a vehicle. The voltage of the vehicle battery 13 is usually 12 V or 24 V in many cases. However, the mobile phone body 9 is generally 3V to 4V
Charging is performed at a voltage of the order of magnitude. For this purpose, a predetermined voltage dividing circuit (not shown) is provided between the vehicle battery 13 and the holder 11, and the voltage is reduced to about 3V to 4V. Note that the charging voltage is an example, and is not limited to 3V to 4V.

The traveling state detecting means provided in the automobile portable telephone system 1 of the present invention detects whether or not the automobile is traveling. This is for controlling the operation of the automobile mobile phone system 1 according to the traveling state of the automobile, as described later. In the present embodiment, as a technique for detecting the running state of the vehicle, the detection is performed by detecting the voltage of the vehicle battery 13. Therefore, the driving state detecting means receives the voltage of the vehicle battery 13. This is because, while the vehicle is running, power is generated by a generator (not shown), and this power is supplied to the vehicle battery 13, and the voltage of the vehicle battery 13 rises more than when the engine is stopped or idling. It is. For example, when the voltage value at idling is set as a reference voltage and the voltage is higher than this,
It can be determined that the vehicle is running.

Although the running state detecting means 3 uses the voltage of the vehicle battery 13, the present invention is not limited to this. It is also effective to use the output of a speedometer mounted on an automobile. This is because a state close to idling of the engine may continue during traveling on a downhill or the like. Further, in the case of a so-called automatic vehicle, the vehicle runs in a creep state. In addition to the speedometer, the traveling state may be detected based on the number of revolutions of the engine. Furthermore, some automobiles are controlled so that the engine speed is automatically increased when the air conditioner is operating. Therefore, it is also effective to set a higher reference voltage value in consideration of this. In addition, the traveling state detecting means 3 may be constituted by a vibrometer, and it may be determined that the vehicle is traveling when vibration of a specific frequency is detected while the vehicle is traveling.

The mobile telephone system 1 according to the present embodiment is provided with a predetermined transmitting / receiving unit 2. The transmission / reception unit 2 has a role of recording and outputting a call signal received from a nearby base station and transmitting a predetermined response signal to the base station. Therefore, the transmitting and receiving unit 2 includes a transceiver 15 for transmitting and receiving a call signal, and a call signal recording unit 5 for recording a call signal and the like.
And call signal output means 7 are provided. Hereinafter, the transmission / reception unit 2 will be described in detail.

The transceiver 1 in the transceiver unit 2 described above
5 is the same as that used for the mobile phone body 9. That is, a communication signal of a predetermined frequency can be transmitted to and received from the base station. Therefore, if an incoming call is received while the automobile is running, the transmitting / receiving unit 2 may automatically respond. And this transceiver 1
The output of 5 is transmitted to the communication signal recording means 5.

The call signal recording means 5 is constituted by a predetermined memory (not shown), and can record a voice signal such as a message from a caller like a so-called answering machine. The memory of the call signal recording means 5 has a function of preferentially holding a newer one of the incoming call signals. Therefore, when a call signal is recorded in the entire memory, the call signal that arrives thereafter is
It is recorded by replacing the oldest call signal in the memory. As will be described later, if the call signal is read once by the driver, the call signal may be positively deleted from the memory, or a specific call signal may not be deleted. It is also effective to do so. Further, the call signal recording means 5 is not limited to a memory,
A normal answering machine or a recording tape partially used may be used.

Further, the communication signal recording means 5 includes:
A predetermined call signal output means 7 is connected. The call signal output means 7 outputs a call signal recorded in the call signal recording means 5 as a voice signal at a predetermined timing. Specifically, like an answering machine,
It has a function of reproducing the recorded call signal like an answering machine. Therefore, the communication signal output means 7 is provided with a predetermined A / D converter, an amplifier, a speaker and the like (all not shown). The call signal output means 7 is provided with a predetermined operation means 17, and the driver can operate the operation means to selectively control the output timing of the call signal and a specific call signal. ing.

Next, the operation and operation of the present embodiment configured as described above will be described in detail.

First, the traveling state detecting means 3 determines whether or not the vehicle is traveling (step S1 in FIG. 4).
This determination is made based on the increase in the voltage of the vehicle battery 13 described above. Next, when it is determined that the automobile is running, it is determined whether or not the mobile phone main body 9 is held by the holder 11 (step S2 in FIG. 4).
The determination of the presence or absence of the mobile phone body 9 can be made based on the energized state of the telephone terminal or the holder terminal. That is, it can be determined by detecting the current flowing through the holder-side terminal. If current is flowing, the mobile phone body 9
Is charged.

In the mobile cellular phone system 1, it is determined whether there is an incoming call (step S in FIG. 4).
3). The presence or absence of the incoming call may be detected by the mobile phone main body 9 or may be detected by the transceiver 15 of the transceiver unit 2. Specifically, when the mobile phone main body 9 detects an incoming call, a change in the voltage of the telephone terminal may be detected. This is because, when there is an incoming call on the mobile phone body 9, the voltage of the telephone terminal changes. Further, since this voltage change is sharper than in the normal incoming call waiting state, an incoming call can be detected accurately. Note that a voltage detection circuit (not shown) for detecting this voltage change may be provided on the holder 11 side. Then, the output of the voltage detection circuit is transmitted to the communication signal recording means 5 described above.

On the other hand, the transmission / reception unit 2 may detect an incoming call. That is, since the transmitting and receiving unit 2 is provided with the transceiver 15 for receiving the call signal, it has the same function as described above.

Then, when there is an incoming call, the incoming call response means 19 of the transmission / reception unit 2 transmits a response impossible signal to the base station (step S5 in FIG. 4). This is similar to the answering function of a general answering machine. Specifically, it transmits a non-response signal indicating that a call cannot be made because the vehicle is driving. Then, if necessary, a non-response signal indicating that a predetermined message can be left is transmitted to the caller. If the caller leaves a message, the call signal of this message is recorded in the call signal recording means (step S6 in FIG. 4). Then, it is determined whether or not the call is disconnected (step S7 in FIG. 4).

When a plurality of incoming calls are received while the automobile is running, the above-described series of recording steps is repeated. As a result, a plurality of messages are recorded in the call signal recording means 5. As described above, while the vehicle is running, the call of the mobile phone body 9 is automatically restricted, and the call signal received by the transmission / reception unit 2 is recorded, so that the driver does not need to deal with the mobile phone. You can concentrate on driving. At this time, it is effective for the purpose of the present invention to display some signal to the driver when an incoming call is received and a call signal is recorded. For example, it is conceivable that an indicator lamp (not shown) is provided at a predetermined location in the vehicle and blinks. In addition, as a method of restricting the telephone call of the mobile phone main body 9, when the voltage applied to the telephone terminal is equal to or higher than a predetermined value, the restriction may be performed. This is the same as the case of the traveling state detecting means.

Next, the step of reproducing the call signal recorded in the call signal recording means 5 will be described. In the mobile cellular phone system 1, when it is determined from the output of the traveling state detecting means 3 that the vehicle is stopped (step S8 in FIG. 4), the communication signal of the communication signal recording means 5 can be output. . This is because, when the car is stopped, there is no problem in operating the mobile phone main body 9 or listening to the message.

More specifically, when it is determined that the vehicle is stopped, it is determined whether or not a call signal is recorded in the call signal recording means (step S9 in FIG. 4). When it is determined that the call signal is recorded, the call signal recording means 5 transmits the call signal to the call signal output means 7 in response to the driver's operation on the operation means 17. Then, the call signal output means 7 outputs a call signal (step S10 in FIG. 4). At this time, the operation unit 17 can selectively perform control such that the latest call signal is output in order, or control that sequentially outputs only the call signals that have not been output. It should be noted that, even when the vehicle is stopped, it is possible to set so that the call signal is recorded in the call signal recording means, like a normal answering machine. This is because the driver may not be able to reach his hand even while the vehicle is stopped.

As described above, in the mobile phone system 1 according to the present embodiment, while the owner of the mobile phone is driving the car, transmission / reception of the mobile phone body 9 is restricted and separate. Transmission / reception unit 2 provided in
Performs the function of an answering machine. For this reason, it is possible to concentrate on driving without being deprived of attention by the mobile phone during driving, and it is possible to reliably record necessary call signals. In particular, the present embodiment is characterized in that the mobile phone main body 9 and the transmission / reception unit 2 are separately provided. For this reason, there is an advantage that the mobile phone main body 9 which has been widely used conventionally can be used as it is with a slight modification.

The case where the portable telephone body 9 and the transmission / reception unit 2 are separately provided as described above has been described. However, the mobile phone system of the present invention is not limited to this. That is, by improving the mobile phone main body 9, it is possible to configure an automobile mobile phone system that functions similarly.

More specifically, a running state detecting means and a communication signal recording means are provided in the portable telephone body. The running state detecting means can be realized by providing a voltmeter capable of detecting the voltage of the telephone terminal. Also, a predetermined memory may be provided as the call signal recording means. In this manner, by providing the necessary components in the mobile phone main body, it is not necessary to separately provide a transmission / reception unit and the like, and the manufacturing cost can be reduced.

In particular, according to the first aspect of the invention, a call signal recording means for storing a call signal received based on an output of the traveling state detecting means, and information of the call signal recording means based on an output of the traveling state detecting means. It is characterized by having a call signal output means. For this reason, according to the running state of the car, the driver can automatically record a predetermined call signal without operating the mobile phone, and can output the signal when necessary, so that the driver can respond to the running state of the car. An excellent effect that an answering machine function can be realized is produced.
Also, there is an excellent effect that it is not necessary to call the base station every time to listen to the recorded call signal.

According to the second aspect of the present invention, the call signal recording means records a call signal received when it is detected from the output of the traveling state detecting means that the vehicle is running, and the call signal output means. Is characterized in that a call signal is output at a predetermined timing when it is detected from the output of the running state detecting means that the vehicle is stopped. As a result, the driver does not need to answer the mobile phone while driving, and can concentrate on driving, and can listen to the call signal recorded by the driver's own operation while the vehicle is stopped. Can be reliably obtained.

According to the third aspect of the present invention, when the mobile phone system detects that the automobile is running from the output of the running state detecting means, the predetermined incoming call answering means outputs an unanswerable signal to the incoming call. It is characterized by having. For this reason, if a message such as a normal answering machine response is transmitted as an unanswerable signal, the caller can know that the called party cannot answer the call, and can send a predetermined message. Can be left.

According to the fourth aspect of the present invention, the portable telephone system is constituted by a predetermined portable telephone main body and a transmitting / receiving unit provided with a predetermined transmitting / receiving device, and the call signal recording means and the call signal output means are included in the transmitting / receiving unit. It is characterized by being equipped. For this reason, there is an excellent effect that the mobile phone main body that has been used more frequently than before can be used as it is.
