Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention provides information-based electronics! The present invention relates to a power input device for a vehicle that drives a power system.

(Prior Art) For example, a main switch is used as a Φ power input device, and the main switch drives a power supply system.

This main switch connects the power supply system by directly actuating the contacts with the key, making the vehicle ready to drive, but in recent years,
A device has been proposed that includes a keyboard and connects the power supply system by indirectly driving the main switch by inputting password information from the keyboard.

(Problems to be Solved by the Invention) As described above, there are power input methods by inputting information from keys or a keyboard, but all of them are operated manually. Instead of such a manual power input operation, when the driver is in the vehicle and ready to drive, if input can be made by voice instead of manually, the power supply system will be automatically activated, making the operation extremely easy.

By the way, in this case, while it is necessary to ensure that the driver's voice is input into the voice input, it is also important to avoid inputting sounds other than voice, such as the driving sound of the internal combustion engine or noise from other vehicles, as much as possible. There is a need to.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a power input device for a vehicle that can automatically and reliably input power without having to manually input power, and that allows easy power input operation. .

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a power input device for a vehicle that drives a power supply system by inputting information, which is provided near the steering wheel, and which generates sound waves in response to vibrations. A voice input means that converts the voice signal into a voice signal with a directivity wide in the vertical direction and narrow in the horizontal direction, a voice recognition means that outputs recognition information from this voice signal, and collates this recognition information with registered information. The present invention is characterized in that it includes an information determining means that outputs an output when the information determining means matches, and a control means that drives the power supply system with the output of the information determining means.

(Operation) In this invention, when the driver gets in the car and emits predetermined voice information, the voice input means obtains a voice signal corresponding to the imaging of the sound wave, and the voice recognition means obtains recognition information from this voice signal. . At this time, the voice input means has a directivity that is optimal for inputting the voice emitted from the position where the driver is riding, and it is difficult to input the driving sound of the internal combustion engine, noise from other vehicles, etc. Then, the information determining means collates this recognition information with the registered information, and when the two match, the control means drives the power supply system, so the power input operation is easy.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

A step 5 and a seat 6 on which a rider 4 rides are provided between a front wheel 2 and a rear wheel 3 that are suspended on a body 1 of a motorcycle. A handle 7 for operating the front wheel 2 is covered with a fairing 9 having a screen 8, and the handle 7 is equipped with a meter device 10. This meter device 1
0, as shown in FIG. 3, a liquid crystal display section 11 is composed of a traveling speed display section 12, a remaining fuel amount display section 13, and a display switchable trip meter/time display section 14. Further, various display lamps 16 are arranged on the right side of the keyboard 15, and an electric distance meter 17 is arranged on the left side.

The keyboard 15 is also provided with an on/off key 18 which is an illuminated key switch, a mode key 20, a set key 21, a reset key 22, and a microphone 23 which is a voice input means.

This microphone 23 converts the sound waves of audio information of the code number emitted by the rider 4 into audio signals corresponding to vibrations, and this microphone 23 is provided in the meter device 10 provided on the handlebar 7, and is also shown in FIGS. 1 and 2. As shown in the figure, it has a directivity that is wide in the vertical direction and narrow in the horizontal direction, and can respond to changes in the sitting height of the rider 4, while also preventing the drive sound of the internal combustion engine and noise from other vehicles from being input. It has become.

The voice signal obtained by the microphone 23 is input to the voice recognition means 24, and the voice recognition means 24 obtains recognition information, which is input to the information determination means 25. The information determining means 25 compares this recognition information with the registered information registered in the information storage means 26, and outputs when the two match. With this output, the control means 27 drives the power supply system via the power supply input means 28.

A more specific control circuit of the meter device 10 is configured as shown in FIG.

29 is a mechanical key switch, 30 is a car battery,
31 is a regulator, which connects approximately 5cm through the power supply stabilization circuit.
is converted to The voltage [V
ccl is a power supply that is constantly supplied, and is supplied to the microcomputer 32 and the clock IC 33.

On the other hand, the power supply Vcc2 obtained through the regulator 34
is the power supply necessary to operate the system, which includes the input interface 35, the A-D converter 36, and the output interface 7A.
, 2, 37a, 37b, 38, the fail-safe circuit 39, the liquid crystal drive IC 40 of the meter device 10, the electronic buzzer 41, and other parts that require a power source other than the power source VcC1.

This regulator 34 is connected to the battery 30 via a switch 42, and a contact 42a of this switch 42 is closed when the output from the microcomputer 32 excites a relay 42b via an output interface 37b. The output signal of the microcomputer 32 is output when the information inputted from the microphone 23 via the input interface 35 matches the information registered in the microcomputer 32.

The running speed signal from the speed sensor 43 is obtained by transmitting the rotation of the front wheel 2 as rotation through a meter cable, rotating a magnet, and turning on and off a reed switch provided near the magnet. Input this on/off pulse to the interface 35
The microcomputer 32 measures the pulse period at the rising or falling edge of the pulse and converts it to vehicle speed.The liquid crystal drive IC 40 converts the calculation result into a segment output necessary for driving the liquid crystal of the meter device 10. ,
An annular zone is displayed on the traveling speed display section 12.

The level signal of the fuel sensor 44 is obtained by a float-type variable resistance sensor provided in the fuel tank, and level changes are obtained as resistance value changes by vertical movement of the float. This fuel level signal is converted into a voltage through an input interface 35 and sent to an A-D converter 36.
This makes it possible for the microcomputer 32 to read it.

The microcomputer 32 converts the calculation result into a segment output necessary for driving the liquid crystal of the meter device 10 using the liquid crystal driving IC 40, and displays the result in an annular zone on the remaining fuel amount display section 13. A reference frequency is provided to the clock IC 33 by a crystal oscillator, and the time is obtained by integrating time from this frequency. This time data is stored in the microcomputer 3.
The time is displayed on the liquid crystal via 2. This display is a switchable display with a trip meter, and the trip meter shares the reed switch signal used in the traveling speed display, which is processed by the microcomputer 32 as distance data, and drives the liquid crystal drive IC 40.

In addition, the microcomputer 32 takes out the input information as an output signal to the outside via the output interface 37a, and outputs signals to the respective on-vehicle devices, such as the ignition circuit relay 45, main switch relay 46, helmet holder 47, horn relay 48, and meter. The power supply system for the illumination light relay 49, electronic buzzer 41, electric distance meter 17, etc. of the device 10 is driven.

Next, the operation of this embodiment will be explained in detail with reference to FIGS. 5 to 7.゛First, in the off mode shown in Fig. 5, when the on/off key 18 is pressed (step a), the process advances to the next mode and determines whether or not a recitation number is registered (step b).
. If it is determined that the recitation number has been registered in advance, the meter device illumination relay 49 is driven and the keyboard 15 is activated.
Initial operations are performed to turn on the illumination lamp and set a timer, and the process shifts to verification mode (step C).

In this verification mode, if the rider 4 utters and inputs a recitation number within 30 seconds without pressing the on/off key 18 (steps d, e, f), the recitation number will be verified against the pre-registered recitation number and a match will be made. If so, it immediately shifts to on mode (step g). If there is a mismatch, a new code number is input by voice in the verification mode and the verification is repeated. If a discrepancy in the input of the recitation number occurs, for example, three or more times (step h), a warning is given by sounding the horn 50 for, for example, 30 seconds;
Turn off the lights and return to off mode (steps i, j)
.

Next, the on mode and wait mode will be explained in detail based on No. 6-.

In the on mode, all the power to the vehicle is inputted by the switch 42, similar to the on state by the normal mechanical key switch 29, the ignition circuit relay 45 and the main switch relay 46 are turned on (steps a and b), and the vehicle starts driving. be done. In this ON mode, the recitation number is changed (step C).

This flowchart is shown in FIG. First of all, speed is OK.
m/h, press the set key 21 on the keyboard 15,
For example, if it continues for 3 seconds or more, the password number can be changed (steps a, b). The timer is started by inputting the set key 21, and the numbers of the recitation number are input by voice (steps c and d).

This recited number is displayed on the clock display, and this recited number can have as many digits as the number of digits shown on the clock display. When this recitation number is input by voice and the set key 21 is input, the recitation number is changed, and if the set key 21 is not input for, for example, 15 seconds or more, the process returns to the start (steps e and f). When the set key 21 is input, the microcomputer 3
The memory discrimination code for which the password number has been input is written in hexadecimal numbers of the FA50 together with the password number in the memory of No. 2, and the change is completed (step g). Thereafter, the power supply system is driven with this changed password number.

When stopping the operation of the internal combustion engine in the on mode, press the on/off key 18 once as shown in FIG. 6 to shift to the wait mode and turn off the ignition circuit relay 45 as well as the main switch relay 46. (Steps e, f). If a mechanical key switch 29 is used, the operation from on to off will perform the same function.

In this wait mode, the speed oxm/h is detected in step g), a timer is turned on at the same time (step h), and after 30 seconds, for example, the illumination light relay 49 of the meter device 10 is turned off, and the transition is made to the off mode (in step 1
). It automatically shifts to off mode, but key operations are required to enter other modes.

In wait mode, for example, press input key 2 on keyboard 15.
When the 1st key of 0 is pressed, the helmet holder 47 is unlocked and locked again after a few seconds (steps i, j
). Therefore, it is only necessary to remove the helmet from the helmet holder 47 within a few seconds after the holder is unlocked. The helmet holder 47 normally has an electric signal turned off, and is energized for only a few seconds to release the electromagnetic lock, so the lock is maintained even if the battery 30 is disconnected.

By turning on the mechanical key switch 29 in this wait mode, the mode can be shifted to the on mode, and by pressing the on/off key 18 once, the mode can be shifted to the collation mode.

In this embodiment, voice input is performed using recited numbers, but it may also be performed using voice information such as alphabets or words.

(Effects of the Invention) The present invention, as in the Kanki, obtains an audio signal corresponding to the vibration of a sound wave of audio information using a directional audio input means, obtains recognition information from this audio signal using a audio recognition means, The information judgment means compares this recognition information with the registered information, and when the two match, the control means drives the power supply system, so when the driver gets in the car and makes a predetermined sound, the power input operation is activated. is performed automatically, making the operation of inputting power extremely easy. Moreover, the audio input means is provided near the handle, converts sound waves into audio signals corresponding to vibrations, and has a wide area in the vertical direction and a shape in the horizontal direction. Since it has a high directivity, it is possible to reliably input the voice from the driver, while reducing the input of other noises.
