Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle information providing system installed in a vehicle such as an automobile.

A vehicle information providing system is a device that provides information useful for driving to passengers such as drivers of vehicles.

Conventionally, as this type of device, a display device that displays a desired road map on a so-called instrument panel in response to a driver's selection operation is already known.

However, in recent years, the interior of a vehicle has come to be considered a type of living space for passengers of vehicles such as automobiles, and more sophisticated information provision capabilities have become necessary. be.

Therefore, the present invention aims to provide a vehicle information providing system (IIM) that can provide useful information such as anticipating various types of υ information desired by passengers.

The vehicle information providing system according to the present invention visually or audibly announces the internal information prepared in advance in the in-vehicle device according to the passenger's selection operation, and combines it with the notified internal information to make it more effective. It is a system that can receive external information such as
The external information may change over time.

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

FIG. 1 shows a vehicle information providing system according to the present invention, in which radio waves carrying at least one external information group are emitted via an antenna 2 from external information fi1 installed outside the vehicle. In this case, the term "external information group" refers to information located outside a group of vehicles that has a unified meaning as a whole; for example, it is a data group that does not represent traffic information, tourist information, popular information, etc. of a specific area. It is. The radio waves are supplied to a receiver 4 via a DI antenna 3. The receiving (8x4) selectively receives a radio wave carrying one of the desired external information BY in response to a reception command from the control circuit 5, demodulates it, etc., and converts it into the original external information group. The decoder 6 decodes the received external information group into a desired format and supplies it to the control circuit 5. Depending on the encoding mode of the received data group as external information, the decoder 6 may The control circuit 5 is formed by, for example, a so-called microcomputer, and causes the -H buffer 1 memory 7 to store a data group carrying external information supplied from the decoder 6.On the other hand, the control circuit 5 is formed by, for example, a so-called microcomputer. It receives supply of any one of the internal information data groups already stored from the internal information memory 8 formed by ROM etc. This internal information data group includes, for example, road maps by area or tourist information. This is video data that shows the scenery of the area, etc. It is also possible to combine this video data with A-dio data such as a general explanation of the tourist spot in question.In addition, internal information method 8 is Control circuit 5
If it is formed in a microcomputer, it is conceivable that it can also be used as a ROM included in the microcomputer. The selection command generation circuit 9 generates a selection command signal in response to the passenger's selection operation using a keyboard (not shown), etc., and the control circuit 5 first generates internal information in response to the selection command signal from the selection command generation circuit 9. One of the data groups is selected, read, and supplied to the buffer memory 7.

Further, the control circuit 5 supplies a reception command to the receiver 4 to receive external information suitable for the selected internal information data according to the content of the selection command signal. In this way, the internal information data and the external information data are stored in the buffer 1 memory 7 in combination.

On the other hand, the buffer memory 7 is supplied with a read timing pulse for controlling the data read timing from the +1114i number generating circuit 10. In this case, the buffer memory 7 also has the memory control al1 function, and the control circuit 5
The designated data is read in response to a control signal from the controller. In this case, the video data is supplied to the video generator 11, and the video generator 11 receives timing signals for video reproduction such as horizontal synchronization pulses and vertical synchronization pulses from the synchronization signal generation circuit 10. is generated and converted into an image t'ta of C, RT12, etc.
It supplies it to the ilTl and controls it to reproduce an image corresponding to the video data group in the buffer memory 7. In the reproduced image, a portion corresponding to the internal information data and a portion corresponding to the external information data may be folded in size, or may appear alternately. A-dio data is usually handled by encoding the limbling value of the audio analog signal and compressing it on the time axis. Depending on the timing signal supplied
Il, read out after the time axis is expanded by the inter-axis expansion circuit 13 'C1)/A change change circuit 14 and the speaker 1
5th class? It is regenerated by trigastric i1i bioregeneration means.

Note that it is also possible to create a configuration that does not use the buffer memory 7 by configuring the control circuit in a microcomputer with a C configuration and supplying the clock pulse to the synchronization signal generation circuit to synchronize the synchronization signal with the clock pulse. be.

Furthermore, if neither the internal information nor the external information includes A' dio data, the time axis expansion circuit 13 and D/
Audio A consisting of A conversion circuit 14' and speaker 15
Of course, there is no need for a regeneration system.

Furthermore, it is not necessary that the external information be fixed; rather, information that changes over time, such as road traffic information or weather forecasts, is more desirable. It would also be good to provide tourist information depending on the time of year.

Therefore, for example, when a passenger performs a selection operation f1 to select a road map of a region to which he or she is about to travel, the selection command generation circuit 9 supplies an appropriate selection command to the control circuit 5, and the system operates organically. Then, along with the road map of the area, road congestion conditions or weather forecasts for the area are superimposed and displayed on the °CRI- or announced audibly via a speaker.

Furthermore, instead of a road map, it is also possible to display colored images of sightseeing spots and attach sightseeing information as external information.

Although it is natural that a part of the in-vehicle anti-noise signal (3 or below) can be received, it is installed in the vehicle, but the external information transmitter 1 and external annana 2, which serve as external information sources, are installed in locations other than the vehicle. However, it is also possible that the external information source is installed on a different vehicle or artificial satellite, so the installation location of the external information source is especially important as long as it is within the range where the external information signal radio waves emitted from the external information source can be received by the on-vehicle antenna 3. It is clear that there is no limit.

Next, another embodiment of the present invention is shown in FIG. In this embodiment, as the external information transmission 1, A broadcasting station 2 is used.
0 is used, and an audio tuner 21 is used to receive audio broadcast radio waves, which are external information radio waves. 21 selectively receives radio waves from a broadcast station selected according to a selection command from the control circuit 5, demodulates the signals, and supplies the demodulated signals to the amplifier 22.Amplifier 22
The demodulated signal is amplified and the speaker 15 is driven to reproduce external information audio. Therefore, in this embodiment, the external information is announced to the passenger as voice without passing through the control circuit 5. Further, the internal information video reproduction system of this embodiment has the same structure as that of the embodiment shown in FIG. 1, and will not be described in detail.

Note that audio A as an external information source in this embodiment
It goes without saying that the broadcasting station 20 does not necessarily have to be an existing broadcasting station, but may be an A-D broadcasting station dedicated to the vehicle information providing system of the present invention.

In another embodiment shown in FIG. 3, the J3 utilizes a C-bit A broadcasting station 30 as an external information source, and the video signal radio waves sent from the in-vehicle amplifier 3 are demodulated by the video tuner 31 and the demodulated video A' The signal is supplied to a video amplifier 32, and the reverse JAA-fr O signal is supplied to an A-DIA amplifier 33 where it is amplified.

The demodulated audio signal amplified by the audio amplifier 33 is supplied as is to the speaker 15 and reproduced as sound. On the other hand, the video signal that has passed through the video amplifier 32 is supplied to the video generator 11 and also to the synchronization signal separation circuit 34, and the synchronization signal separation circuit 34 separates various timing signals such as vertical and horizontal synchronization pulses from the demodulated video signal. These signals are then supplied to the synchronizing signal generating circuit 10. The synchronization signal generation circuit 10 is a synchronization signal separation circuit 34 bX
Various timing signals such as horizontal and vertical pulses synchronized with these timing signals are generated to supply the dough to the puffer memory 7 and the video generator 11.

In this way, the video information as internal information and the external information obtained through the video tuner are the same as the CRT.
It is reproduced and displayed superimposed on or over the intersection. Other than the above, the configuration and operation are the same as those of the embodiment shown in FIG. 1, so a detailed description thereof will not be given.

Although it is conceivable to utilize the existing TV 1lis [transmission] as a video broadcasting station, the system of the present invention (l
River video broadcasting station II! It would be a good idea to put it there.

Furthermore, it goes without saying that an audio reproduction system is not required if the station is a dedicated video broadcasting station and broadcasts only the TA information.

FIG. 4 shows still another embodiment of the present invention, in which a telephone exchange lI4 is used as an external information source.
At least one code signal generating circuit 41 connected to the subscriber side or the trunk side of the mobile telephone 11i43 connected to the subscriber terminal is used. Therefore, the code signal generation circuit 41 and the car phone transmitter/receiver l1
143, the code signal generated from the code signal generating circuit 41 is radiated via the external antenna 2 on the car telephone radio wave. On the other hand, a car telephone device 44 equipped with an automatic dialing function is provided on the in-vehicle receiver side. The car telephone device 44 controls (1) dials an appropriate telephone number in response to a selection command from the circuit 5, captures the desired code signal generation circuit 41, receives the code signal as external information, and sends the code signal to the decoder 6. Other than the above configuration, the configuration is the same as that shown in FIG.

Note that the code signal is a digital signal that carries a variety of information such as road traffic information, weather forecast, and tourist information.

Further, in place of the code signal generation circuit 41, an audio signal generation circuit including a tape recorder or the like is used to amplify the audio signal that has passed through the car telephone device 44 on the receiving side, and the audio signal is reproduced as it is through a speaker. Therefore, the following transformations are possible.

In any of the embodiments of the present invention described above, external information from an external information source should not always be combined with internal information that is selected and notified to the passenger, but external information should be incorporated according to the passenger's will. It is also possible to decide whether or not to do so.

In such a case, the selection command circuit 9 may transmit the passenger's intention to the control circuit 5 by supplying the information in Table 1. The control circuit 5 then determines whether or not to avoid operating the receiving system in accordance with this information.

As is clear from the above, the vehicle information provision system according to the present invention combines internal information pre-stored in the on-vehicle device with external information from an external information source and notifies the passenger. Compared to the in-vehicle information provision III, it is possible to notify passengers of road traffic information that is richer and changes from time to time in accordance with the exit route map of the vendor station. This makes it possible to provide extremely useful information to passengers.

In other words, the in-vehicle information providing system according to the present invention provides external information that changes over time or is too loud to be stored in the in-vehicle device in advance, with respect to fixed information prepared in advance in the in-vehicle information providing device. This system makes it possible to add external information that requires memory or is too detailed and notify the passenger, providing a wide range of information to the passenger so that they can enjoy a more comfortable driving life. .
