Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a keyless entry device, and more particularly to an improved keyless entry device that allows modification of a password within a single room.

[Prior art] Instead of a door lock device using a general key, recent vehicles use a PIN number known only to the user to unlock the vehicle door without using any keys. Keyless entry devices have been put into practical use.

According to this keyless entry switch, it is no longer necessary for the user to possess the key, and thereby the trouble caused by the loss or theft of the key can be avoided.

Furthermore, the electronic lock line of such a keyless entry device is used not only to simply unlock the door, but also to perform various additional functions such as opening/closing the trunk room or window, as well as providing an alarm against theft. This provides many conveniences for vehicle users.

Conventional J3 keyless entry devices have an entry switch installed on the outside of the vehicle, usually in a relatively inconspicuous part near the doorknob, accept the user's PIN III number, and check whether this matches the registered value. The release of the door lock is controlled by this.

However, the above conventional keyless entry device
t) Correctly modifying and inputting the 11 number must be done using an entry switch installed outside the vehicle, and in either case, if someone is nearby during operation, there is a possibility that the password will be leaked. Furthermore, even under conditions of use where there is a risk of leakage, conventional devices require the registration number to be corrected again outside the vehicle, which is a drawback in that it is not a fundamental solution to preventing accidents due to theft or mischief. was there.

[Object of the invention] The present invention has been made in view of the above-mentioned conventional problems, and
The purpose is to provide an improved keyless entry device that allows the user to register his/her personal identification number inside the vehicle and thereby modify the identification number without the knowledge of others.

[Structure of the Invention] In order to achieve the above object, the present invention includes a password correction device provided inside the vehicle interior separately from the entry switch, and a password correction device provided inside the vehicle interior for displaying the password. a display, and the password correction device allows the password code to be set in the vehicle interior.
A feature is that the F number can be modified.

[Description of Embodiments] Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a schematic composition of a vehicle to which the present invention is applied, including a part of the driver's seat and a part of the driver's side door.

In the figure, the switch 12 is made up of one or more switches for starting the system and inputting the password during keyless entry, and is located on the outside of the vehicle, for example on the driver's side door 1. The number is printed near the doorknob, etc.

The entry switch 12 is electrically connected to the control unit 14, and the control unit 14 compares the pre-stored password and the input number input from the entry switch 12, and if it is determined that they are the same, locks the door ljM 8416. to unlock the door.

A feature of the present invention is that the password can be corrected inside the vehicle, and for this purpose, the password correction device 18 that corrects the password stored in the control unit 14 is different from the entry switch 12. It is installed separately inside the vehicle.

Here, the password modification switch 18 is preferably composed of two types of switches, one for incrementing and one for decrementing, in order to enable arbitrary modification of the password.

It is also preferable that the password correction device 18 be used in combination with a switch having other functions that cannot be easily operated by anyone other than the vehicle owner, or as an accessory switch.

The display 20 is connected to the control unit 14 and is configured to display the password at least when the password is modified. Here, a digital car clock, which is turned off when the engine is stopped to prevent battery loss, is suitable as the display for the vehicle keyless entry device. Of course, in the present invention, other digital displays such as a speedometer, distance meter, or television monitor may be used, and furthermore, a display dedicated to the keyless entry device may be used.

In this embodiment, in order to prevent the driver from forgetting the PIN number due to modification of the PIN number, the ignition key switch 22 is connected to the control unit 14, and the number of seconds immediately after the ignition key switch 22 is turned on. It is also preferable to configure the display 20 to display the password for only seconds.

The keyless entry device according to this embodiment is configured as described above, and the password correction function and display function are performed as follows.
This will be explained based on the diagram.

In the figure, when the ignition key switch 22 is turned on, the timer is reset to -H in step 102 and started, and the elapsed time of the timer is compared with a preset time TI (several seconds) in step 104. Iaii on the display 20 repeating 104 and 106
Continue displaying the LE number. When the timer predetermined time T1 has elapsed, the process proceeds to step 108, where the timer is stopped, and as is clear from step 110, the f-digital car clock used as the display 20 returns to the normal time display.

In cases other than when modifying the 111'J identification number, step 1
12.114 moves in the "N O" direction and the display 20 continues to display the time, but when correcting the password, the increment switch or accremen 1 to switch provided in the password correction device 18 is turned on. So, in any case, from step 112 or step 114'
In the YES direction, the process proceeds to step 116.

In step 116, once the timer for preventing erroneous correction operation has been reset, the star 1-su1 step 11 is restarted.
At step 8, the elapsed time of the timer is compared with a preset time T2, and the display of the password is continued as at step 120 until the two match.

When the timer has elapsed for a predetermined time T2, the process advances from step 118 to step 122 to stop the timer, and further, in steps 124 and 126, it is confirmed whether or not the increment switch or the increment 1 switch is kept pressed.

When it is confirmed in step 124 or 126 that the -C increment 1 or decrement switch continues to be pressed, the dark-Y number is incremented or decremented in step 128 or 130.

Then, from step 128 or 130, Stella 1116
If the user returns to , and if the password needs to be further modified, the increment or decrement switch Gj is held down to continue modifying the password in the same manner as described above.

On the other hand, if the switch has not been pressed in steps 124 and 126, the process returns to step 110 and the display 20
starts displaying the normal time again and no corrective action is performed. In this way, by requiring the IO identification number correction device 18 to continue operating for a certain period of time to correct the PIN, even if the PIN correction IJI device 18 is activated by mistake, the PIN can be changed immediately. There's no need to put it away.

As described above, according to this embodiment, the driver can safely and securely modify the PIN number inside the vehicle.
Ij3 i:II This has the advantage that even if the M number is revised, it will not be forgotten.

In this embodiment, a keyless entry switch for unlocking a door has been described, but it goes without saying that the present invention can also be applied to other functions such as opening and closing a trunk room or a window.

[Effects of the Invention 1] As explained above, according to the present invention, the password correction device is provided in the vehicle interior separately from the entry switch, and the dark M number display is also provided in the vehicle interior. This has the effect that the number can be corrected safely and reliably.
