Description

Voice guidance device for vehicles

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice guidance device for a vehicle, and in particular, the geographic information is recorded in order in a memory device before driving, and whenever necessary, the voice information can be provided by voice by simple switch operation, and can be implemented at a low price. To a voice guidance device for a vehicle

In general, it will be geographic information that must be accompanied to drive the vehicle. When driving on unfamiliar roads, most drivers have no choice but to use the map. Conventional vehicles do not have the ability to voice geographic information, so if there are no passengers, the driver may stop the vehicle and view the map, or It's a hassle for the driver because you have to drive while looking at the map, which can cause serious accidents.

On the other hand, in the vehicle navigation system, which is currently commercialized to provide the convenience of geographic information, indicates the current position of the vehicle on the map appearing on the display unit by the transmission and reception between the satellite and the vehicle, and the target point at the current vehicle position when the target point is input. By displaying the trajectory of the shortest distance to the driver, the driver can easily understand the geography, thereby providing better geographic information.

However, such a vehicle navigation system is equipped with a function to inform the driving method by a high-end model or by voice, and they also can not provide information about the major junctions by voice guidance, and because the price of the system is quite expensive, the general user It is a burden to them.

An object of the present invention is to record the geographic information in order to the memory device before driving in order to solve the above problems, and can provide the guidance of the geographic information by voice whenever necessary by simple switch operation, can be implemented at a low price The present invention provides a voice guide device for a vehicle.

In order to achieve the above object, the apparatus of the present invention comprises a command input unit for generating a command signal for recording and playback; A voice input unit converting and amplifying the input voice into a voice signal and outputting the amplified voice; A memory unit for storing the voice data; A voice reproducing unit for reproducing and outputting voice data read from the memory unit by the reproducing command; And converting a voice signal output from the voice input unit into voice data in response to the recording command signal, sequentially writing the converted voice data into a predetermined address area of the memory unit, and responsive to the recording command signal. And a control unit which sequentially reads the voice data written in the unit, converts the voice data into a voice signal, and provides the voice signal to the voice reproducing unit so that the converted voice signal is reproduced.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a voice guidance apparatus according to the present invention, as shown, a command input unit 10 for generating a command signal for recording and playback, and converts and amplifies the input voice into a voice signal A voice input unit 20 for outputting, a memory unit 40 for storing the voice data, a voice reproducing unit 60 for reproducing and outputting voice data read out from the memory unit 40 by the reproducing command; And converting the voice signal output from the voice input unit 20 into voice data in response to the recording command signal, and sequentially converting the converted voice data into a predetermined address area of the memory unit 40, and recording the signal. In response, the voice data written in the memory unit 40 is sequentially read and converted into a voice signal, and the voice signal is provided to the voice reproducing unit 60 so that the converted voice signal is reproduced. It consists of a control unit 80.

Referring to the overall operation of the embodiment configured as described above are as follows.

Referring to Figure 1, the command input unit 10 includes a recording switch and a playback switch for recording and playback, these switches are installed on the steering wheel in a position that is easy for the driver to operate, reference numeral 1 is a microphone It is preferable to be installed in a position where reception is easy.

In the present invention, the driver may store geographic information about the main branch point to the target position before driving in the memory. For this purpose, the driver simply presses the recording switch of the command input unit 10 and the device of the present invention is ready for recording. In this state, the driver may input the geographical information about the branch point by voice through the microphone 1 by voice.

Once the voice geographic information is input, the voice input unit 20 converts the voice signal into an audio signal corresponding to the input voice, amplifies the voice signal to a predetermined level, and outputs the voice signal to the control unit 20, that is, the microcomputer.

In this case, since the amplified voice signal is an analog signal, the controller 80 generates voice data obtained by converting the signal into a digital signal and generates a predetermined address signal to generate an address area of the memory unit 40 corresponding to the address signal. The audio data is written in the following. After that, if the driver presses the recording switch again to toggle, the recording function is released.

In the recording function of the present invention, during the second recording, the recording switch may be repeated by pressing the recording switch twice within a predetermined time. In this way, you can record as many as the number of major branches.

On the other hand, during regeneration, the driver presses the regeneration switch of the command input unit 20. If the playback switch is pressed, the command input unit 10 generates a playback command signal to the control unit 80, and the control unit 80 responds to the first of the plurality of audio data written in the memory 40 address areas. The written audio data is read out and converted into an audio signal, which is an analog signal, and the converted audio signal is provided to the audio reproducing unit 60.

Then, the voice reproducing unit 60 amplifies and converts the voice signal provided from the control unit 80 into voice, and reproduces the reproducing command after reproducing through the speaker 2.

If you want to listen to the next recorded voice, press the play switch once more to read and play the next voice data.

According to the present invention, since the recording quality required by the vehicle may be considerably low, a large amount of content can be stored using a small capacity semiconductor memory. In addition, by using a semiconductor memory, a power source for driving a motor is not required as in a general cassette, and it is possible to operate at low power.

In addition, the device of the present invention can be used to improve the car audio.

Accordingly, in the present invention, as described above, the geographic information is recorded in the memory device in order before the driving, and the guidance of the geographic information can be provided by voice by a simple switch operation of the driver whenever necessary. In addition, there is an effect to reduce the possibility of accidents.

In addition, since the voice guide device can be implemented at a low price, there is another effect of reducing the burden on the user.
