JPH0692201A - Burglarproof device for vehicle - Google Patents

Abstract

PURPOSE:To lock a door by remote operation even if a hood or a trunk is opened and to discriminate the set condition of a burglarproof device from the outside of a vehicle. CONSTITUTION:When normal sending wave is received, a door is controlled to be locked and unlocked regardless of the opening and closing condition of the door (step 2-4 and 9). When all doors are closed and locked, a burglarproof device is set and the set condition is displayed (step 4-8).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antitheft device for a vehicle, and more particularly to an improvement of a device for controlling locking or unlocking of a door and setting or resetting of an antitheft device by remote control.

[0002]

2. Description of the Related Art Generally, in a system having a door control function and an anti-theft function, all doors (including a hood and a trunk) must be closed in order to set the anti-theft device. Therefore, when a remote control function is added, the door can be locked or unlocked when the door (including the hood and the trunk) is open, but the anti-theft device cannot be set. Therefore, the anti-theft device is set. There is a problem that it cannot be determined from outside the vehicle whether or not the vehicle is present.

Further, when the door is open, the lock of the door and the setting of the anti-theft device are prohibited, when the door is closed, the lock or unlock of the door and the setting or the reset of the anti-theft device are performed, and at that time. There is a system that blinks turn signals or tail lights, but in this case, for example, the door cannot be locked even if the remote control is operated with the trunk or hood open (the trunk or hood automatically locks when closed). There is a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and enables the door to be locked by the remote control operation even when the hood or the trunk is open, and the antitheft device can be set. When it is operated, it is possible to determine whether it is possible to control only the locking or unlocking of the door by displaying it by, for example, a turn signal of the vehicle.

[0005]

In order to solve the above problems, according to the present invention, there is provided a device for controlling the locking or unlocking of a door and the setting or resetting of an anti-theft device by remote control, the opening and closing of the door. A means for controlling the locking or unlocking of the doors regardless of the state, and setting the anti-theft device when all doors are closed and locked and indicates that the anti-theft device is set There is provided an antitheft device for a vehicle, which is provided with:

[0006]

According to the above construction, during remote control, when any door (including the hood and trunk) is open, the locking or unlocking of the door is controlled,
Also all doors (including hood and trunk above)
When the door is closed, locking or unlocking of the door is controlled, and when the door is locked, the anti-theft device is set, and the setting is indicated by, for example, blinking a turn signal (or tail lamp). To be done. Note that when the door is unlocked, the anti-theft device is reset, and at the time of the reset, a display different from that at the time of the setting (for example, a display having a different blinking number) is displayed, so that the anti-theft device is set and reset. Can be discriminated from outside the vehicle.

[0007]

1 shows the structure of a vehicle antitheft device according to an embodiment of the present invention. A battery power source B and a door are provided on the input side of a microcomputer 52 provided in the antitheft device 5. Door courtesy switch 2 that is turned on when opened, trunk courtesy switch 3 that is turned on when the trunk is opened, hood courtesy switch 4 that is turned on when the hood is opened, and reception that receives radio waves transmitted from the transmitter 1. The output side of the circuit 51 is connected. On the other hand, on the output side of the microcomputer 52, a door control 6 for controlling locking and unlocking of the door, an LED
The indicator 7, turn signal or tail lamp, horn, etc. are connected.

FIG. 2 exemplifies a processing procedure performed by the microcomputer shown in FIG. 1, in which initialization processing is performed in step 1, and in step 2, the transmitter 1 sends a regular identification code having its own identification code. It is determined whether or not the transmitted radio wave has been received. If it is determined in step 2 that there is a transmission radio wave, the process proceeds to step 3,
It is determined whether the flag is "0" (that is, the door is unlocked).

If the determination in step 3 is YES (door unlock), the process proceeds to step 4 and the door lock output is sent to the door controller, and then the flag is set to "1" in step 5. Furthermore, it is determined in step 6 whether all doors (including the trunk and hood) are closed. If yes (all doors closed), the anti-theft device is set in step 7 and the turn signal flashes once. To be done. Next, at step 8, the flag is set to "2".

On the other hand, if the determination in step 3 is NO (that is, the door is locked and the flag is "1" or "2"), the process proceeds to step 9 to unlock the door to the door controller. Output is sent.
Next, at step 10, it is judged if the flag is set to "2". If yes, the routine proceeds to step 11, where the anti-theft device is reset and, for example, the turn signal blinks twice, and the step 12 Then, the flag is set to "0". On the other hand, when the determination in step 10 is NO (when the flag is "1"), the process directly proceeds to step 12 and the flag is set to "0".

When the regular transmission radio wave is received in this manner, the door (including the hood and the trunk)
The door is locked or unlocked regardless of the open / closed state of the door, and the anti-theft device is set when the door lock output is sent with all doors closed,
Further, the set state is displayed, for example, by blinking the turn signal once. On the other hand, when the door unlock output is sent while the anti-theft device is set, the anti-theft device is reset, and the reset state is displayed, for example, by blinking the turn signal twice.

[0012]

According to the present invention, even when the hood or the trunk is opened, the lock of the door can be controlled by the remote control operation, and the operability can be improved. When the anti-theft device is set, the set state is displayed by, for example, a turn signal of the vehicle, so that it can be determined from outside the vehicle that the anti-theft device is being reset.
