A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a block diagram of the overall configuration of a driving information display device according to the present invention, and in the center of FIG. It also contains a memory circuit.

Various devices are connected to the arithmetic and control circuit 1, and first of all, considering the vehicle as a car with a carburetor, the input side includes a distance sensor 2a provided in the odometer 2, and a residual fuel detection device provided in the fuel tank 3. The sensor 3a and a fuel flowmeter 5, which is a flow rate sensor provided in the middle of the fuel supply pipe 4, are connected to the arithmetic control circuit 1 via their respective waveform processing circuits 6. Further, on the output side, a display 7 and a drive circuit 8 for driving the display 7 are connected, as well as an audio signal generation circuit 10 for generating audio from a speaker 9 and a circuit 11 for synthesizing audio. In addition, 12 is a keyboard, which is disposed at a location in the driver's seat where it can be easily operated by the driver, and includes operation keys for causing the display 7 to display a predetermined display.

Further, 13 is an oscillation circuit, and 14 is a power supply circuit, both of which are circuit elements required for the operation of the arithmetic control circuit 1.

In the above configuration, the arithmetic control circuit 1 has the distance -t=
7 via a, information on the remaining fuel from the residual fuel detection sensor 3a, information on the fuel flow rate from the fuel flow meter 5, which is a flow rate sensor, and input the information related to the driving distance on the keyboard 12. The speaker 9 is operated according to a preset program by the operator's operation of the operation keys.
The display 7 operates to display predetermined travel information on the display 7 while generating sound.

In the EF ■ specification vehicle, instead of the signal from the flow sensor, the signal sent from the electronically controlled fuel injection circuit unit 15 to the fuel injection nozzle 16 is input to the waveform processing circuit 6, and then input to the arithmetic control circuit 1. .

Next, a specific operating mode will be explained.

First, FIG. 2 specifically shows the display 7, and FIG. 3 specifically shows the keyboard 12. When normal running information is not displayed, the display section 7a of the display 7 displays the time and functions as a clock.

Suppose you drive a car towards the destination to be synthesized. Information about the fuel for this drive.

The information is displayed to the driver separately before departure, while driving, and after arrival. The display will be as shown below.

Before departure, when the key 12a on the keyboard 12 is operated, the speaker 9 produces a voice saying "Please enter the distance to the destination" after the pronunciation "Bing-pon". When the driver inputs the distance by operating the key 12b in response to this, the input distance value is displayed on the display 7a, and then a beep is heard followed by a voice saying, ``Required fuel is approximately.'' A numerical value representing the required fuel is displayed on the display section 7a in units of liters. Next, after a "beep" sound, a voice saying "Current residual fuel level" is heard and the display 7 appears.
A value representing the residual fuel is displayed in liters. Next, there is a beep sound, followed by a voice that says "You have arrived at your destination", then a beep sounds and the display 7a starts displaying the time again, and the drive continues for more than 2 degrees, returning to the clock. Before departure, when the driver inputs predetermined information related to the drive according to voice instructions, the predetermined fuel information for the drive is displayed on the display section 7a along with the voice guidance under certain operations. be done.

Similarly, when trying to obtain fuel information while driving, by operating the key 12C on the keyboard 12, the following messages will appear: "Ping-dong", "What is the fuel consumption so far?"``Beep'', ``Required fuel is approximately''``Beep'', ``Current residual fuel is''``Beep'', ``Refueling is required'' Degree display section 7-
After the information is displayed, the display section 7a returns to the clock.

If the key 12d associated with the fuel consumption monitor is operated while the vehicle is running, the fuel consumption will be displayed on the lower display section 7b of the display 7.

When attempting to obtain fuel information after arrival, the key 12C is operated. In this way, a sound and a voice will be heard from Hepica 9 saying, ``Ping-dong'', ``I have traveled the entered distance.'' The display section 7a displays the information each time, and after the information is displayed, the display section 7a returns to the clock. If you arrive at a destination different from the distance originally entered and you operate the above key 12c, the above voice guidance saying "ping-dong" and "you have traveled the entered distance" will not be provided. Instead, the following operations are performed.

In the above case, if you want to maintain the display while the vehicle is running, you can operate the key 12e.

If the key 12e is operated again, the display section 7a returns to the clock.

Through the above-described operations, the driver can easily determine the fuel consumption status, whether refueling is necessary, etc.

Next, another method of using the keyboard 12 will be explained.

The operation key 12f is a key that can input the vehicle speed.1 For example, before departure, operate the key 12b to input the distance to the destination, and operate the key 12f to input the vehicle speed as the planned average vehicle speed. , the estimated time of arrival at the destination is displayed on the display section 7a. While driving, press key 12q.
Each time you operate, the distance traveled up to that point, average vehicle speed,
The expected time of arrival, progress toward the schedule, degree of delay, average vehicle speed for arriving on schedule, etc. are displayed on the display section 7a. When you arrive at your destination and press key 12 (J), you will receive a message informing you that the entered distance has been traveled.
The average vehicle speed, elapsed time, and distance traveled are displayed, and when the vehicle arrives at a location other than the destination, there is no notification that the entered distance has been traveled. In the above, when the above-mentioned display items are displayed, a sound is produced and a sound informing the display contents is played in the same manner as described above. When the display on the display section 7a ends, the display section 7a displays the time. Furthermore, by operating the operation key 12h as an independent key, it is possible to display the speed per second of the own vehicle.

In the above usage method, only one average vehicle speed was specified, but by dividing the driving section to the destination into two and specifying a separate average vehicle speed for each section, the average vehicle speed can be adjusted while driving. It is also possible to switch to display driving information. In this case, after operating the key 12f related to vehicle speed, operating the key 121 to divide the section, then inputting the first average vehicle speed using the key 12b, then operating the key 12f again, and then operating the key 12j. Then, the second average vehicle speed is input by operating the key 12b. Key 12i before departure
is set to obtain driving information based on the first average vehicle speed by operating the key 12j, and while driving, the average vehicle speed is changed from the first to the second by operating the key 12j. do. In the above, the operation of the display device is as explained above.

In addition to the above, it is also possible to change the initially set distance and the initially set average vehicle speed while driving.

Furthermore, if an operation error is made, for example, if the keys 12c or 12g are operated even though no data has been input, the system is configured so that the content of the operation error is announced by voice.

As is clear from the above □ explanation, according to the present invention, a voice generating device is attached to a driving information display device for a vehicle, and such a display device The ease of use has improved, which in turn has made it possible to improve vehicle drivability and reduce fuel consumption.
