In this case, if the key fob is illuminated for a long period of time, the battery will be wasted, so if the key fob is illuminated only for a predetermined period of time during which the password is entered, the battery will be consumed or saved.

This invention has been made in view of the above circumstances, and it sets a verification mode for verifying a PIN number for a predetermined period of time.
It is an object of the present invention to provide a power supply input device for a vehicle that can return to an initial state when an accident occurs, thereby reducing battery consumption.

(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 an electrical system by inputting a password from a keyboard equipped with an illumination light. ) Equipped with a control circuit that maintains a verification mode for a predetermined period of time in which the password entered from the F keyboard is verified by turning on the NFF lighting lamp, and then turns off the lighting lamp and returns to the initial state after the predetermined period of time has elapsed. It is characterized by

(Function) In this invention, the electric system including the two ignition systems is driven by inputting a password from the keyboard. A verification mode is set for a predetermined period of time, in which the illumination light is turned on when a PIN code is entered using the key fob, and the entered PIN number is compared with the official PIN number, and after this predetermined period of time has elapsed, the illumination light is turned off and initialized. restore the condition. Therefore, when entering a password at night, the consumption of the battery used to illuminate the keyboard can be minimized.

(Example) Hereinafter, an example in which the present invention is applied to a motorcycle will be described in detail based on the accompanying drawings.

is a speed sensor, which constitutes an input means of the control circuit 4. The mechanical keys 1 and the keyboard 2 are power input means for the electrical system including the ignition system of the vehicle.

The output signal of the mechanical key 1 is input to an on/off operation state determining means 5 forming a control circuit 4. The on/off operation state determining means 5 determines whether the output signal of the mechanical key 1 is input or not, and outputs the output signal to the system operation/inoperation setting means 6 when the output signal is input. This system operation/inoperation setting means 6 drives a main switch relay 7, and when the mechanical key 1 is operated, power is input to the electrical system.

Output signals from the keyboard 2 are inputted to a password verification mode switch input determination means 8, a password determination means 9, and a password change determination means 10.

When the verification mode switch for verifying the password of the key fob 2 is operated, the operation is judged by the password verification mode switch input determination means 8, and the password determination means 9 is activated for the time set by the timer 11, and the key fob illumination is activated. Drives relay 12. The time set in Tie 7]1 is the time to maintain the verification mode for verifying the PIN number.
After the predetermined period of time has elapsed, the operation of the password determining means 9 is stopped to restore the initial state of deafness.

Therefore, when entering your PIN code at night, the keyboard 2
Battery consumption for lighting can be minimized.

When a password is input from the keyboard 2, the password determination means 9 determines whether the password is appropriate, and when a setting password is input, it outputs it to the system operation/inoperation setting means 6, and the main Drive switch relay 7.

This PIN number determination means 9 determines whether the F@ID number has been input from the keyboard 2, and if the PIN number does not match more than a predetermined number of times in a row, for example, 3 or more times, the PIN number consecutive mismatch number determination means 1
3 drives the horn relay 15 via the alarm output drive circuit 14, and the horn is set to [B] to issue an alarm.

Therefore, even if a user attempts to steal a vehicle and inputs a password more than a predetermined number, the horn will sound, which is effective in preventing theft of the vehicle.

Additionally, if the user makes a mistake when entering the PIN, the horn will sound, clearly informing the user of the error, prompting the user to enter the correct PIN, and providing other means such as , mechanical key 1
In a vehicle in which the main switch can also be input, input can be performed using the mechanical key 1. Further, the PIN number consecutive mismatch count determination means 13 simultaneously outputs a signal to return the PIN number determination means 9 to its initial state.

Therefore, there is an advantage that no special key operation is required to cancel an erroneous key input, and that the operation can be performed from the initial state, and the operation is simple and easy to understand.

After the vehicle has stopped, the password change determination means 10 determines the output signal from the speed sensor 3 using the speed signal determination means 16, and the system operation/inoperation setting means 6 is activated based on the output signal from the mechanical key 1. When you are
A signal is output to the password writing means 17. The password writing means 17 writes a new password into the password memory 18, and thereafter, based on this password, the password determining means 9 determines whether or not the password has been entered properly.

42 etc.

The running speed signal of the speed sensor 3 is obtained by transmitting the rotation of the surface width as rotation through a meter cable to rotate a magnet, and turning on and off a leet switch provided near the magnet. This on/off pulse is waveform-shaped by the input interface 20, and the 8-bit microcomputer 22 measures the pulse period at the onset or fall of the pulse, converts it to a heavy speed, and sends the calculation result to the liquid crystal drive IC 42. Then, the segment output is converted into a segment output necessary for driving the liquid crystal of the meter device 25, and an annular zone is displayed on the traveling speed display section 32.

The level signal of the fuel sensor 45 is obtained by a float-type variable resistance sensor provided in the fuel tank, and level changes are obtained as resistance value changes by upward driving of the float.

sound.

This horn relay 15 also sounds a horn 54 when a proper password is not input for a predetermined period of time or more when inputting a password from the keyboard 2. In addition, electronic buzzer 4
3 sounds when an input is made from the keyboard 2 to notify the user of the key input.

Next, the operation of the present invention will be explained in detail with reference to FIGS. 3 to 5.

First, in the off mode shown in FIG.
enters the operation to verify the PIN number, and checks whether or not the PIN number has been matched (step b).
. This is due to the battery 37 being disconnected, etc., causing the PIN number to change to the 8-bit password memory 18 of the microcomputer 22.
If the password is missing, the mechanical key 1 is input (step C).

By inputting the mechanical key 1, the relay 44b of the switch 44 is actuated to turn on the contact 44a, thereby shifting to the on mode.

If the password is rejected in 711, the meter device lighting relay 52 is driven to turn on the lighting lamp that illuminates the keyboard 2, and the initial operation of setting the timer 11 is performed to shift to verification mode. (Step d).

This timer 11 is set with the time during which the verification mode operates, and when a predetermined period of time has elapsed, the illumination light is automatically turned off and returned to off mode (step k), and the illumination light can be turned on by key operation at night. We make it easy.

Enter the specified password using the input key 28 within 30 seconds after the on/off key 26 is pressed.Steps e, f, g
), when the set key 29 is pressed, the password is checked against the pre-stored password in the 8-bit microcomputer 22,
If they match, the mode immediately shifts to off-mode (step h). If they do not match, enter a new PIN in verification mode and repeat the verification. In case of this mismatch,
Since the initial state of the verification mode is restored, no key operation is required to cancel an erroneous key input.

If there is a mismatch in the input of the password, for example, three or more times (step i), the horn 54 is sounded for three seconds as a warning, the lighting is turned off, and the mode returns to off mode (steps j, k).

Next, the on mode and wait mode will be explained in detail with reference to FIG. 4.

In on mode 2, all power supplies of both ili are turned on in the same way as when the mechanical key 1 is turned on. That is,
When the password is input from the keyboard 2 to the 8-bit microcomputer 22 from the input interface 20,
Relay 44b of switch 44 moves, contact 44a closes, and power supply Vcc2 is supplied. As a result, the ignition circuit relay 4 is controlled via the 8-bit microcomputer 22.
9. Drive the main switch relay 7 (step a.

b).

Even when the mechanical key 1 is operated, the operation signal is sent to the 8-bit microcomputer 22 via the input interface 20.
When the password is input, this signal is accepted and the switch 44 can be operated as if the password had been input.

In this on mode, the password is changed. This flowchart is shown in FIG.

In Fig. 5, first, if the speed is set to OK m/h and the input of the set key 29 on the keyboard 2 is continued for more than 3 seconds, the ID number can be changed (steps a and b).
. The reason why the set key 29 is required to be input for 3 seconds or more is to prevent the password from being changed when the set key 29 is pressed by mistake.

The timer 11 is started by inputting the set key 29, and the numbers of the password are inputted by using the large key 28 (step c
, d). The digits of this password are determined by the number of keys entered, and can range from 1 to 10 digits. Enter the number and press set key 2
When 9 is input, the password is changed, and if the set key 29 is not input for 15 seconds or more, the process returns to the start (steps e and f).

When the set key 29 is input, the password memory 18 of the 8-bit microcomputer 22 stores the password as well as the stored identification code 16 of the FA50.
The change is completed by writing in base numbers (step g).

When changing the PIN number, for example, if the battery 37 is removed, the PIN number and the f'lJ code will disappear from the 1st prefecture code memory 18, and only the mechanical key 1 can be operated. If you remove it, you will need to enter your PIN again.

Therefore, if you know the master code, for example, if you have an 8-bit microcomputer or master code, you cannot remove the battery and input the master code to move the vehicle, making it difficult to steal the vehicle. .

When stopping the operation of the internal combustion engine in the on mode, press the on/off key 26 once as shown in FIG. Off step d, e.

f), the headlights go out.

At this time, the display on the meter device 25 disappears, but the illumination lamp remains on and the keyboard 2 remains illuminated for a predetermined period of time.

When the mechanical key 1 is used, the operation from on to off has the same effect.

In wait mode, the speed is set to 0 to detect m/h (steps e, f, g), and at the same time, the timer 11 is turned on (step h), and 30 seconds later, the meter illumination light relay 52 is turned off, and the mode is shifted to off mode (step m, 0). It automatically moves to off mode, but key operations are required to access other motes.

In this wait mode, use the input key of keyboard 2 to steal W.
If lf1 is set and the vehicle slopes over a predetermined level 1-, theft f
i! The alarm device is activated (step i.

j). Further, when the No. 1 key of the large key 28 of the keyboard 2 is pressed, the helmet holder 50 is unlocked and locked again after a few seconds (step 1). Therefore,
After key-in, it is necessary to immediately remove the helmet from the holder. The helmet holder 50 normally has an electrical 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 37 is disconnected.

By turning on the mechanical key 1 in this wait mode, it is possible to shift to the on mode, and by pressing the on/off key 26 once, it is possible to shift to the collation mode.

(Effects of the Invention) As described above, in a power input device of a vehicle that drives an electrical system by inputting a password from the keyboard, the control circuit turns on the lighting lamp by inputting the password from the keyboard. The verification mode is maintained for a predetermined period of time, and when the predetermined period of time has elapsed, the illumination light is turned off to return to the initial state, so when entering a PIN code at night, etc., the battery that illuminates the keyboard can be used. Consumption can be minimized.
