ff and an input/output ink FF 5d are shown.

The input/output interface 5d of the controller 5 includes
Ignition switch 3.1 to switch 7, foot switch 9, trunk switch 11, door lock detection switch 13.4 to cylinder control switch 15 are connected, and the operating status of each of these switches is monitored by controller 1 to roller 5. Is it like that? Said 1-A suit differential is installed corresponding to each door (t, j), and when the 1-a is heard, it will turn ON, and when the door or the opening saw is heard, it will turn OFF. The switch from 1 to 2 is controlled by the open/closed state of the hood, and if the switch is opened or opened, the switch will turn ON.
It is a switch that makes OF+=sound when closed. ] - The rank switch 11, like 11j, monitors the open/closed states of the rank switches 1 to 1, and is turned on when the I-rank is heard, and turned off when it is closed. The door lock detection switch 13 is a switch that turns OFF when the door is locked in h color and turns ON when the door is unlocked. The key cylinder unlock switch 15 is
: is the switch that turns on when the door lock is unlocked. Further, an indicator lamp 17 and a relay 19 are connected to the controller 1 and the controller 5, which are controlled by the input/output interface 11 through the input/output interface 15d. The indicator lamp 17 is controlled by the controller 5 and displays various statuses, and the relay 19 is driven and operated by an alarm signal from the controller 5, thereby causing the It activates and generates an alarm.

Next, the use of P is explained using the reference 1 shown in FIG. 2. When the ignition switch f-3 is in the OFF state and the door, hood, and I-rank are closed, the corresponding switches 1 to 7, foot switch 9,
When the trunk switch 'l'1 is in the OFF state, the door lock is in the unlocked state, and the door lock detection switch 13 is in the A state, these states are detected by the controller 5 and the vehicle theft detection is detected. The preventer is in the released state (step 100) and the indicator light 17
has the 'a''l j:] state (step 110).
3. The indicator lamp 17 is installed in the meter, on the instrument panel, on the door trim, or on the door knob so that it can be seen from outside the vehicle. When the door is opened in this state, the door switch 7 is turned on and the indicator lamp 17 blinks (step 120).
, 130). Then, when the door is locked by operating the 1" knob on the door, the door lock detection switch 13 is turned OFF, and the indicator lamp 17 changes from a blinking state to a continuous lighting state (steps 140 and 160), thereby preventing theft. indicates that it is now possible to shift to alert state. If the door is closed without being locked in step 140, the door lock detection switch 13 is ON and the door switch 7 is OFF, so the indicator lamp 17 goes out and becomes unlocked (Step 150). ).

If all the doors are closed when the indicator lamp 17 is lit continuously to indicate that it is possible to move to the alert state, the door switch 7 is turned OFF and the indicator lamp 17 remains lit. However, at this point, the timer operates and -C (steps 180, 19
0>, the light will automatically turn off after a certain period of time, indicating that the anti-theft device has entered the alert state Step 2
10°220). Therefore, the indicator lamp 17
It is possible to confirm that the anti-theft device is fully alert by observing the display change, which lights up for a certain period of time after the door is closed and then turns off. In J5, step 190, when the ignition switch 3 is turned on while the timer is running or the door is unlocked by -1-1 and the key cylinder unlock switch 15 is turned on, the anti-theft device is in the released state (

The timer starts operating as soon as the alarm state occurs, and stops the alarm after a certain period of time (steps 250 and 270).
, 280). This is to prevent the battery from being consumed in driving the alarm 21 and horn 23 that display the alarm status.However,
If the key cylinder unlock switch is not turned on in the alarm state and the state where the alarm has stopped (steps 250 and 280), the system returns to the alert state again.
Do) Nosuichi again supervises rank switch 11 to foot switch 9.1? ! -=Jru (step 240). Therefore, if any of these switches is still in the ON state, the alarm state will occur again.

These operations are performed by the key cylinder unlock switch 15.
This is repeated until the key is turned on, the door is unlocked with the key, and the key cylinder unlock switch 1-15 is turned on.
Only when the anti-theft alarm is turned on, the anti-theft alarm status is canceled and returns to the canceled status.

By the way, in this conventional vehicle anti-theft device,
The display state of the indicator lamp is determined in steps 13o, 160. '+90 As shown in 90, the door first flashes when it is heard, then when the door is locked and the door lock detection switch is turned OFF, the light turns on, but then all the doors close. Beware of getting caught 1/
(Even when the timer starts operating to shift to the state, it remains lit and does not change, so at 11'J when I closed the door after operating the door lock knob and locking the door, the door did not close completely and was only partially closed.) When the platform is in the door state, the engine coolant lamp 17 will turn on 4g if it is left on continuously, and it is difficult to recognize this door ajar state.
In addition, there was a problem in that the anti-theft device was mistakenly set to the alarm state, and the alarm state was not set.

[Purpose and Summary of the Invention] This invention has been made in view of the above, and its purpose is to make the opening/closing body installed in the vehicle body open. In a vehicle anti-theft device that is set to the alert state once and issues an alarm when the theft occurs, the vehicle anti-theft device that prevents a mistake in setting the alert state due to the half-opening of the opening/closing body is provided. -!J thing.
