Abstract

PURPOSE:To perform a dial operation with high safety and no error even under driving of a vehicle, by delivering in the data of the remote side corresponding to a dial code accordant with a key operation. CONSTITUTION:A control board provided on a steering wheel is connected electrically to a fixed control unit attached to the main body of a vehicle by means of brushes BA1-BA2. When the telephone number of the remote side is supplied via a key switch 90, a CPU1 transfers this telephone number to a CPU2. The CPU2 delivers the telephone number in voices through a sound output unit 200. At the same time, the name of the remote side is delivered in voices if it is previously registered. The operator confirms these voices and has a calling operation. Then the CPU2 calls automatically the remote side via a mobile device. Thus the operator can talk to the remote side via mikes MC1 and MC2 and a speaker SP set to the main body of the vehicle.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an on-vehicle telephone device in which a dial key provided on a steering wheel near the steering wheel is used to manually dial the telephone device. .

In ItL vehicles, the steering wheel is closest to 1-lime, and it is also closest to 1-lime, so it takes 1-lime to operate.
In order to improve this, it is desirable to install an operation board equipped with key switches for controlling vehicle equipment in the center of the steering link wheel.

However, since the steering mechanism that transmits the rotation of the wheel to the steering shirt 1- is complicated, the wiring of the signal cable connecting the operation boats 1 to (steering operation boat) installed in the center of the steering link wheel and the fixed control unit 1- is complicated. However, in order to make the wiring easier, the steering mechanism must be replaced! In addition, wiring pipes and/or slip rings for connection must be installed in a manner that does not interfere with the operation of the steering mechanism, and the space allotted to the steering mechanism is limited. Wiring is quite difficult.

Therefore, the present applicant proposed a method (1) in which the operating board 1- and the fixed control unit 1- are connected using slip links and printing lines, and power transmission and signal transmission are carried out via the lines.
We proposed patent application No. 13292 (Sho 5). child,!
Accordingly, it is possible to transmit the power supplied to the operating board and a large amount of information generated from the operating board 1 without using a large number of lines.

By the way, when a telephone device is installed on a vehicle, the telephone is generally placed in the center between the driver's seat and the passenger seat so that the person in the passenger seat or the rear seat can also use the telephone. However, when 1-Lime tries to dial the phone, he must hold the receiver with one hand and dial with the other hand, so he cannot dial the phone while driving the vehicle. Therefore, the present applicant proposed a steering control board 1-dial signal transmission system (Japanese Patent Application No. 188723/1983), which facilitates the dial operation of the driver by providing a tire key on the steering control board 1- near the steering wheel. Proposed. However, even when this is used, it is necessary to manually operate the dial while driving the vehicle, and it is easy to operate the dial incorrectly. If you make a mistake when dialing a phone, it will cause trouble for the person on the other end, so it is best to dial when the vehicle is stopped.

The present invention is a vehicle whose primary purpose is to have a dual-talk device that allows the driver to operate the dials safely and without error while driving the vehicle, and to confirm the details of the dial operations. - having a secondary purpose of providing a telephone device;
The third purpose is to provide a telephone device that allows you to make a call to a specified destination even if you do not remember the telephone number of the other party, and the third purpose is to provide a telephone device that allows you to make a call without having to hold the receiver. To accomplish this purpose,
In the present invention, a dial key is arranged on the operation board 1 on the steering wheel, and a dial key corresponding to the key operation is applied to the telephone device, and a dial key corresponding to the key operation is applied to the telephone device. Data, that is, phase-[a destination data storage means for storing destination data such as the name of the destination, and ? 'fμ synthesis means is provided to output the data of the other party as voice according to the dial code. Then, if there is no key operation for J-Confirmation after a predetermined period of time, or if there is a key operation that invalidates the dial code 1~, the generated dial code is updated to a different value. That is, for example, if voice data of the name of the other party is registered in advance in the other party's data storage means, the name of the other party is outputted by voice by performing a predetermined dial operation. If the voice output destination name, etc. is different from the desired destination, 5 If you do not proceed with the confirmation operation, the tying code will be automatically updated and the tying code will be automatically updated and the tying code will be automatically updated. The name, etc. will be output aloud again. Note that the dial code 1- in the present invention includes an ordinary dial coat made of a silk combination of abbreviated dial codes 1-5, an area number, and a user number -y. According to this, you can hear and confirm the person you are about to call, so you can use the dial key.
When operating 1-Lime, there is no need to confirm the key to be operated with 11. Therefore, 1-Lime can safely dial a telephone device without making a mistake while driving a vehicle. Also, even if Trime forgets the phone number of the other party that is registered in the device, if you key in the number or low number and wait, the name of the other party you want will eventually be output by voice. At that time, by performing a confirmation operation, you can make a call to the desired destination.

1-Rime 1-When dialing a telephone, the driver operates the dials by hand, so he often uses abbreviated dials that require fewer keystrokes. Therefore, in one preferred embodiment of the present invention, the destination data and voice output for speed dialing are performed.

The destination data varies depending on the user, and a huge amount of memory is required to store in advance the destination data that satisfies all the user's requests in the destination data storage means. Also,
When audio data is provided for each character, the transition between the characters in the output audio becomes unnatural, so the audio is best kept short.

Accordingly, in one aspect of the present invention, the destination data storage means is a non-volatile read/write memory, and an acoustic-to-electrical converter lower stage such as a microbon is provided.

To enable a user's voice to be converted into data and input into a destination data storage means.

The pulse signal with a period of 2'F divided by 8 by the counter C○1 of "io) is applied to the J input terminal of [79, etc.".Primbuflow knob F9.
At the output end of the inverter TN+9, a reference signal with a pulse width (period of high level H) of i'/4 and a cycle of 21 is obtained. This reference signal has a period less than 2, so when it is applied to a separate path from the frequency band described above, the 1-frequency discrimination circuit distinguishes this signal as data rOJ and lowers the demodulated output signal. Sera 1-.

FIG. 5c shows the operation timing of the external input priority circuit.

This will be explained with reference to FIG. 5c. The FSK signal from the waveform shaping/differentiation circuit (signal output from NA3) is applied to the inverter INIC+ and the Nant gate -NA3. The output signal of the inverter [N10 is
A13, and the output signals from Chin1-games1 to NA8 are applied to the reseller 1-input terminal R of counter 02. A clock pulse of T/4 period is applied to the input terminal CK of the color CO2 and the flip-flop F7.

1” S K signal is applied to the external input priority circuit Jt,,
Inverter [NIO input terminal is low level] 7, etc.

``In synchronization with the clock pulse of /4 period, the output terminals of the flip-flop F7 and Q are set to H and ■, respectively.
, is set to . The signals from the output terminals of gate 27 and Q are respectively connected to
5. Nandoge-1-NAl4. NA15 and NAl6 are signal selection circuits that selectively select the FSK signal or the reference signal from the n1i reference signal generation circuit according to the states of the outputs 1XAf Q and Q of the flip-flop F7. Apply to the frequency discrimination circuit shown below. When the Q of the Furinozo and Norono knob F7 is set to (), the FSK signal from the inverter IN17 is applied to the frequency brake r circuit. Then, the reseller 1 of the counter CO2 is set to 1 or 1, II.

CO2 starts counting the clock.

If the period of the FSK signal is 1', the counter C'l 02
When the count is 0, ], 2.3, it is reset to 1- again due to the state change of the primary 1・゛SK signal, and it becomes 0 again.

5.6 and Karan 1~ and reseller 1~.

In other words, when there is an FSK signal, regardless of whether the period of the FSK signal is T or 2T, the reset signal () is not applied to the reset 1-input terminal R of flip-flop F7, so the door output terminals and Q are held in the state of t1 and I-, respectively.In addition, in this state, a high level tl is outputted at a predetermined timing to the output end Q of the control flow knob F8, so that the inverter lNl
The FSK signal manually input to 0 is the Nant gate NΔ1

Applied to Δ14. Here, the high level l-1 is applied to the other input terminal of the Nant gate NΔ14, so the FSK signal is applied to the frequency discrimination circuit via NA14 and NΔ1G. Also at this time, Nanto game
Since one input terminal of 1-NA 15 is at low level T, the reference signal from the reference signal generation circuit is not output from NA 5.

When the FSK signal is no longer applied, the counter CO2
The counter CO2 is O, ], 2, 3, 4° 5.6, 7, 8 since the Cera 1- is no longer applied to the counter 1 at 6.
．． 9 and continue counting. CO2 count value is 9,
That is, when 3T has elapsed from the start of counting, a high level (reset level) H is applied to the input terminal R of the reseller 1 of the flip-flop F7 via the NAND game l-NA3 and the inverter IN1.6, and F7 is reset. 1
- to be done. As a result, the output terminals and Q of the flip-flop F7 are inverted to L and 1-1, respectively.

When C5 of 1.'7 becomes H, a reset signal is applied to counter CO2. This reset signal is then applied to the inverter lNl0 at a low level L, causing the Q of F'7 to be low.
It continues until it is set to 1 again. When the levels of the output terminals Q and Q of the Noritsubflonobu F7 are inverted, the Nandt gate NA I /I is closed, and NA15 is opened instead, and the reference signal from the inverter IN19 is transferred to the frequency block via the Nandt gate NA I G. ? Applied to a separate circuit.
