There is one described in vice Bul 1et111.

Based on this device, the applicant of the present application previously applied for patent application No. 58-1.
Nos. 58037-158040 (unpublished) propose a vehicle theft prevention device with improved quality performance such as ease of use. First, the proposed device will be explained based on the circuit diagrams shown in FIGS. 1 to 5 and Fucco sheet 1.

In FIG. 1, a battery 1 is mounted on a vehicle, and the vehicle is being driven using this battery 1.

The microcomputer 2 is made operable regardless of what happens after the vehicle is left parked.

Place the ignition switch 3 on the driver's seat of the vehicle.
This is a switch that turns on when the key switch is turned to the ignition position.

The unlocking operation detection switch 4 is installed on a vehicle door or trunk, etc., and when the lock IXi 4M is unlocked by inserting the cylinder into the cylinder and turning it to the unlocking side. These are switches that turn on almost simultaneously.

Similarly, the locking operation detection switch f-5 is a switch that turns ON at 11J1 when the key is similarly inserted into the key cylinder and rotated toward the locking side, which is approximately the same as when the lock I is locked.

The door switch 6 is turned on when one of the interior doors 7 is listening to fdj, '? When the I-pet is completely at 1311, it is an A-turn switch.

The foot switch 7 is turned on when the vehicle's notebook (bonnet) is turned on, and is fully turned on (A when the foot switch is turned on).

The 1-rank switch 8 is a switch that is on when the 1st to rank of the vehicle is listening, and is off when it is completely closed.

The lock state detection switch 1] is a switch that turns on when any of the locks installed on the vehicle interior sound door is unlocked, and turns off when all of the locks are locked.

As will be described later, the indicator lamp 10 is used to warn the door ajar or to display the status of an anti-theft device during operation. There is.

The relay 11 is driven by the output of the microcomputer 2 and energizes the alarm lamp 12J3 and alarm horn 13.

The alarm lamp 12 and the alarm horn 13 are used to issue a warning when opening/closing parts of the vehicle body, such as vehicle doors, L-ranks, hoods, etc., are accessed by unauthorized means, respectively.

Next, the basic 4T operation of this vehicle anti-theft device will be schematically explained with reference to FIG.

In order to prevent this type of anti-theft device for vehicles from functioning properly, it is necessary to set the operation of the device to a state that prevents unauthorized intrusion.
Alternatively, it must be impossible to escape from the unauthorized intrusion standby state.

This is done when passengers get on or off the vehicle, or when they return to an unattended vehicle from the vehicle station, insert the key into the key cylinder, release 1 and 1, and lock the vehicle. This is to prevent an alarm from being flashed by jL't when asking the rank etc. to 11.

Also, taking into consideration that you may forget or forget to read Let's 1, let's rehich (・
It would be unreasonable to require the person at the vehicle yard to perform special operations such as ``Swift f operation'' when parking the vehicle and leave it there, so it is difficult to require the person at the vehicle yard to perform special operations such as Returning to the vehicle inside the vehicle, the left and right of the vehicle are 1" 41 m 5! l [Prevention equipment automatically activates] -
It is preferable to be set or reset.

Therefore, in this Y-head, following the initial processing in the J, the, or F section (10), it is checked in the SEDIT section (20) whether or not the car operation has been performed as described above.

For example, the vehicle driver turns off the engine, locks the locking mechanism on each door except the driver's door, gets out of the vehicle, and starts driving. Close the door, insert the key into the key cylinder installed on the driver's door and turn it in the locking direction, or turn off the engine and lock each door except the driver's door. This is done by sequentially confirming that the driver has locked the vehicle, gotten out of the vehicle, pushed down the lock knob on the driver's door to lock it, and then closed the door using the so-called A-less lock operation41.

In the next step (30), IIT approves the fact that the vehicle was left unattended after being parked! First, we will confirm that there are no crew members onboard.

This M[authentication process is performed in step (20) with
During operation (11f is confirmed, the engine is started within a certain period of time, or if the 1-1 cylinder is turned on again, 1-1 is
This is done by determining whether the door is closed or not.

In this way, when the vehicle operation (lir recognition, @(1 absence confirmation) is completed, the operation of the device is automatically rested to the unauthorized intrusion standby state, that is, the theft prevention process in step (40) is started. will begin on 17jf.

This theft alarm will immediately issue an alarm if any of the vehicle doors, trunks, hoods, etc. are stolen by unauthorized means.

On the other hand, 1) J'3 is in the middle of the 1-width operation I'l II "recognition processing (20), the correct position error (1-ru I C recognition processing (30)), and the i '] or to indicate the presence of a crew member 11), the operation of the device 6 is resumed as shown by the dotted line in the figure.
Returned to 11 3゜Also, theft prevention l2 place (!l! <
4.0) -) In 1111, for example, a train station goes to the key ring and inserts 1- into the door or I.
- When a proper act such as asking for rank snow was committed, as shown in the dotted line 1, the theft 11 prevention process (40) is returned to the M vehicle inspection fI l+1c recognition process (20>), and the device The operation is re-hit from the F'+I intrusion standby state f-saw.

Therefore, if the vehicle owner hears the door or 1-rank by normal means, a warning will not be issued inadvertently.

Next, the 6Y details of the gl-width operation Louis recognition process will be specifically explained with reference to FIG.

This 151 car operation confirmation 82 process is performed when the driver's fortune is 1: i- to park the vehicle, enters 4- into the key ring and presses 1'' on door 7, and 1'' turns the door 7 without using the key. Press and hold L to close the door (so-called -1-)
Two methods are used to deal with the two cases: one is locked by a single slotter operation, and the other is a case where the slotter is locked.

Now let's assume that the vehicle is running.

In this state, steps (100)→(101)-.

Here, Parking Operation Confirmation Office]] 1-1111: If the verification result is incorrect, for example, if the door is closed and the locking machine (1°4) is locked for both Φ ITJ departures, Assuming that, in such a case, the ignition switch (j) would normally be turned on before the lamp timer's secondary time is completed.

Then, the execution result of step (203>) becomes Y[-8, and the occupant absence confirmation process is reset and returns to the vehicle operation confirmation process, which prevents the vehicle from erroneously transitioning to the unauthorized intrusion standby process. is prevented.

21k, In the middle of the occupant absence confirmation process, the vehicle owner returns to the vehicle and inserts the key into the key cylinder to release the lock mechanism. It will be set.

On the other hand, J3 Ruru 1 is required for Ru 1 vehicle operation 4 + IC recognition processing.

Also, when the alarm timer ends, step (306
)'s conclusion is YES and 4j, then the sweep (307) is executed, the alarm is temporarily stopped, and the operations from the J-slap (301) are repeated.

On the other hand, when the vehicle owner returns to the vehicle and inserts the key into the key cylinder while waiting for unauthorized intrusion or when the alarm is activated, the unlock operation detection switch is activated. Step (301) fl:
The execution result of (305) is YES, and the unauthorized intrusion standby state returns to the unauthorized intrusion standby state, and the alarms are stopped.

By the way, in such a vehicle anti-theft device,
In general, the door 1 cock is located quite far away from the door 1 cock machine 4:4, and the key cylinder that has been pressed is placed at a considerable distance from the door 7.
The connection between the two is via a transmission mechanism consisting of levers and links.
C-connected.

For this reason, one vehicle has one production! Considering IT, it is necessary to consider obtaining the operational play of the system from the key cylinder to the lock device 474 with uniform accuracy for each product.If this is not taken into account, the key cylinder ’ After inserting the key and performing a locking operation, if the key cylinder is turned too far in the unlocking direction when pulling the key out of the key cylinder, the unlocking operation detection switch may be turned on by mistake. , the occupant is absent (i [1 place j (11) is reset, and there is a risk that a failure to enter the unauthorized intrusion standby state may occur.

Above; 5 improvements to correct setting errors caused by operating the key cylinder without intending to unlock the lock:

(Description of Embodiments) Figures 7 to 0 are flow diagrams -1 showing the control f order of the dual-use anti-theft device according to the present invention.
JO, in Figures 7 to 9, at 13, the above Figures 3 to 5.
Explanation of the same components as those shown in the figure will be omitted.

In addition, regarding the bird core configuration of the device of the present invention, the first
161-, so the explanation will be omitted.

In this example device, the original problem of the invention is
Inserting the key into the key cylinder (・After locking, when pulling out 4-, the unlock operation detection switch is turned on incorrectly (A) In addition, the following three embodiments solve special problems.

This is because when the key is inserted into the key cylinder of the trunk, the unlock operation detection switch malfunctions when you pull it out. To prevent the confirmation process from being replayed, and when the device is in the unauthorized intrusion state, the key cylinder 15' To prevent an anti-theft operation from being erroneously removed when a fraud is committed, such as accidentally activating an unlocking operation detection switch by approaching a strong magnet to a J. The purpose is to prevent the alarm from sounding even if the unlocking operation detection switch is erroneously operated using the powerful F41ri when unauthorized intrusion is detected in the theft ff111 prevention device line and the alarm is sounding.

The embodiments shown in FIGS. 7 to 9 will be described below, focusing on how these problems are solved.

First, insert the key into the 1-rank key cylinder to unlock the lock, open the trunk, or similarly insert the key into the door key cylinder.
s, then use the keyless lock operation to lock the lock device 41.
When the door is in the state where the knob lock is pressed down to lock the door (the door is still open), the parking operation confirmation process shown in Fig. 7 is executed, and steps (100) → (101) → (1
02) → (103) → (104) → (1050) → (
1'051)→(1060-)(103) are executed repeatedly, and the indicator lamp is continuously lit.

In this state, when you pull out the key from the key cylinder of ranks 1 to 3 or the key cylinder of the door, you accidentally
Assume that the C key cylinder is turned too far in the unlocking direction, thereby accidentally turning on the key cylinder unlocking operation detection switch 4.

In this case, the execution result of step (1051) is YES, and then step (1052) is executed and the timer is started.

Thereafter, step (1053) is repeatedly executed until the end of the timer is detected in step (1055>), but in this state, the door is locked; The execution result of > is NO, so the operation confirmation process during 51 is executed.
1. There's no way you'll be let down.

Then drive, for parking operations! 19 Close the door, insert the key into the key cylinder, and then lock the lock mechanism.
If the key cylinder is turned too far in the unlocking direction when pulling the key from the key cylinder and the unlock operation detection switch 1 is turned on by mistake, or when the user is trying to retrieve luggage, the key cylinder is turned too far in the unlock direction. To the vehicle inside: 3. After inserting the key into the key cylinder of 1 to rank lυ and unlocking it, when entering the 1 to rank again and subtracting 4- from the key cylinder to leave 1, the above Similarly, assume that the unlocking operation detection switch 4 is turned on by mistake.
5, Suup (2031) fruit (j unity t, l

], the timer is heard, and C″l is executed.

Thereafter, until it is determined that the timer has ended in step (2035), steps (2033) → (203/I) → (
2035) → (2033) is executed repeatedly, but in the same 4iK as mentioned above, this state C is a slap (2033 >.

The execution result of (20371) is No and 41, so there is no possibility that occupant absence 1i1f recognition 11: will be erroneously let.

Next, while the anti-theft device is in the state of preventing intrusion, a strong magnet is used to
~Rank unlocking operation 1' [Detection switch was turned on by mistake]
Let's consider such a case.

In this case, J3 is at the theft prevention station J'1 in Fig. 9, the actual result of step (3011) is YES, I: I, and then step 7 (3012> is a3 and the timer is is started.

Thereafter, steps (3013) → (3014) → (
3015) → (3013) is repeatedly executed, but as described above, in this state the door locking mechanism is in the locked state, and the rank b IW] is known (to 1), so steps <3013> and (3014) are executed. ) is the execution result b
No, therefore, the rδ+f11 prevention process will not cause unauthorized intruder samurai state hsI etc. to be recalled by mistake.

In general, when J3 was in the process of preventing theft, an unauthorized entry was detected, and the 7 alarm was sounding, the door and 1
-Rank -1--Cylinder If? Assume that the lock operation detection switch f is operated by a strong magnet.

In this case, the execution result of the mail order (3050) at J3 in the theft protection 11 J11 in FIG.

Thereafter, until the end of the timer is determined in step (,3054), step (3054,) → (30b 3
) → (3054) → (3052) are repeatedly executed, but in this state J5 is in the locking machine 4115 of each door is IJ11! Since the trunk in the locked state is also closed, steps (3054) (3053)
The execution results of both are No, and therefore the alarm never stops sounding.

In addition, if a normal M operation is performed, the anti-theft device will go through the parking operation confirmation process and the occupant absence confirmation process, and will be in the unauthorized intrusion i3i1 state, and will not detect any unauthorized intrusion. Of course, Ala-1\ will be illuminated.

(Effects of the Invention) It is clear from the above description of the embodiments that, according to the present invention, in the anti-theft loading for small vehicles, it is possible to apply this to the door and the key cylinder of ranks 1 to 1 for the vehicle 1i11 city. After inserting the key and locking the lock mechanism, when pulling out the key from the key cylinder, the key cylinder was turned too far in the unlocking direction, which caused the unlock operation detection switch to malfunction. In addition to preventing ζ placement mistakes, there is no need to modify the device for multiple purposes, so there is no loss of equipment.
It has 9 effects.
