CONSTITUTION:First closing bodies 3-5 are locked in the closed state and one of the first closing bodies 3 is finally closed by a keyless door lock so as to create a first warning state led by the action of an ultrasonic sensor 100, but when a second closing body (a back door) 4 is opened using a key in the above mentioned state, the action of the ultrasonic sensor 100 stops and the shifting to a second warning state takes place. When an engine is attempted to start without a key in this state, a horn 6, a flash light 8 and a cut switch are actuated at the time of an ignition switch 20 being turned on. When the shifting by a breakdown truck is attempted without starting up the engine, a burglary detecting means 115 is actuated by the output of wheel speed sensors 110F, 110R so as to drive the horn 6 and the like and emit an alarm.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an anti-theft device for a vehicle.

(Prior art) Generally, when a passenger leaves the vehicle, even if the door or other opening/closing body is closed and locked, a thief breaks the lock or window glass to unlock the door, opens the door, and steals the item. There are also cases where someone steals a vehicle by starting the engine by operating the ignition switch with a metal fitting, etc.

In response, each opening/closing body of the vehicle is sequentially closed and locked.
For example, if you lock the last door in the closed state without a key (keyless door lock), you will be in an unconditional alert state, and you will not be able to perform procedures other than the predetermined operating procedures, such as unlocking the door or other opening/closing object without a key. Anti-theft devices for vehicles have been known in the art, which are configured to issue a warning alarm or disable the vehicle if the ignition switch is turned on under such conditions. (Refer to Japanese Patent Application Laid-open No. 60-50050).

Reference numeral 11 denotes a bugler control unit that constitutes the central part of the vehicle anti-theft device.

In addition, for example, the room lamp 1 in the center of the ceiling of the vehicle l
01 is installed with an ultrasonic sensor (intrusion detection sensor) 100 that radiates ultrasonic waves uniformly over the entire interior of the vehicle and detects the reflected waves. In the case of this embodiment, the horn 6, the cut switch 7 and the flasher light 8 constitute a warning activation means, and the notification light 9 and the buzzer 10 constitute a notification means that informs the occupant of the status of the anti-theft device. In addition, wheel speed sensors 110F each detect the rotation speed of the front wheels and the rear wheels,
llOR are provided respectively.

Next, an abnormal state detection means of the vehicle for operating the anti-theft device will be explained.

First, the ignition 2 is provided with an ignition switch and a key switch for detecting the presence or absence of an engine key, and each of the first to third opening/closing bodies 3 to 5 is provided with a key switch for detecting the open/closed state thereof. - Third opening/closing detection means 13 to 15 are provided, and the first and second opening/closing bodies 3.4 are provided with a first detection means for detecting the use of a key to a key cylinder for locking.
The first opening/closing body 3 is further provided with a lock alarm means 18 for detecting locking by a manual lock knob linked to the locking means. In the case of this embodiment, it is determined whether the driver has left the vehicle l or not based on the presence or absence of the engine key.

Next, FIG. 2 shows the overall configuration of the control system section of the vehicle anti-theft device, and this device operates when at least one of the ignition switch 20 and the key switch 21 is turned on. It is in the released (inactive) state.

Now, the bugler control unit 11 has an initial state setting section 22 for entering the alert state, a first alarm preparation section 23 for creating the first alarm preparation state deaf, and a second alarm preparation state for entering the actual alarm state. a second alarm preparation section 24 for creating a first alarm state; a first alarm state setting means 25 for creating a first alarm state;
A second alarm state setting means 26 that creates an alarm state, and a return child vjt2 that returns from the second alarm state to the first alarm state.
7, an operation control means 29 for creating a first operating state and a second operating state for activating the warning operating means 28, an ultrasonic sensor 100, and wheel speed sensors ll0F and llOR provided on each front and rear wheel. and a theft detection means 115 that calculates the logical sum of these sensors.

The first alarm state setting means 25 and the second alarm state setting means 26 send a part of their output lines to the ultrasonic sensor 100, which is the intrusion detection means for detecting the intrusion of a person into the vehicle interior. The ultrasonic sensor monitor 00 and theft detection means 1 are connected to each other from the first alarm state setting means 25.
The ON command signal that activates the ultrasonic sensor 15 is also transmitted from the second warning state setting means 26 that turns the ultrasonic sensor OFF.
An I''F command signal is supplied to each.

The operating states of the above system, the conditions for continuation and transition of the operating states, and the output contents are described in the third section.
It is as shown in Figures (a) and (b).

Hereinafter, the operations and effects of each of the above-mentioned setting sections or setting means will be specifically explained.

First, the initial state setting section 22 receives off signals from both the ignition switch 20 and the key switch 21, and
The entire system of this device is set to the initial state upon receiving the closing signals from the first to third recessed/closed detection means 13 to 15, and then returned to the released state upon receiving an on signal from at least one of the ignition switch 20 and the key switch 21. .

The first warning preparation section 23 that receives the initial signal sets the device into a first warning preparation state when receiving an open signal from at least one of the first to third opening/closing detection means 13 to 15, and then sets the device to a first warning preparation state. When the off signal is received from the third opening/closing detection means 13 to 15 and the conditions for the next second warning preparation state are not satisfied, the state is returned to the initial state. Further, this main warning means sounds the buzzer IO for a short time when setting the first warning preparation state with the open signal of the first opening/closing detection means 13.

The second alert preparation state 24 receives the signal from the first alert preparation section 23 and the second! The alert state setting means 25 constitutes a first alert setting means 30. That is, the second alert readiness state 24
In the first warning readiness state, the second and third open/close detection means 14.15 close signals and the first and second key detection means 16 are detected.
．． 17 off signal (key not inserted),
In this state, the signal from the first key detection means 16 remains off, and the close signal from the first open/close detection means 13 and the lock detection means 18
When the lock signal is received, the device enters the second alarm preparation state. Then, the first alert state setting means 25 sets the device to the first alert state when the time TI (for example, 15 seconds) set by the first timer 31 has elapsed from the second alert preparation state.

Then, at the time point when the time T1 has elapsed, the ultrasonic sensor 1
00 to realize the unconditional first alert state.

Further, upon receiving the first warning signal, the operation control means 29 activates each opening signal of the first to third opening/closing detection means 13 to 15, the lock release signal of the lock detection means 18, and the ON state of the ignition switch 20. A first alarm state is entered in which the alarm activation means 28 is activated in response to all signals. In other words, all of these signals serve as triggers for alarm activation.

Further, the second vigilance preparation section 24 sets the set time ゛r,
If the condition for continuation of the second alert preparation state is no longer satisfied before the time elapses, the state of the device is left to the initial setting section 22 to determine. Further, the first alert state setting means 25 receives an ON signal from the first key detecting means 16 in the first alert state (
When cancel condition A) or an on signal is output from the key switch 21 and an on signal is output from the ignition switch 20 (cancel condition B), the state of the device is left to the initial state setting section 22 to determine.

Furthermore, in the second alarm preparation state 2.1, the notification lamp 9 is turned on in the first half of the set time 1'' of the first alarm preparation state, and the notification lamp 9 is blinked in the second half, and the first alarm preparation state Buzzer 10 sounds for a short time when transitioning to . On the other hand, the first
The alarm state setting means 25 causes the notification lamp 9 to blink in this first alarm state of deafness.

Next, when the second alarm state setting means 26 receives an ON signal from the second key detection means 17 in the first alarm state, it first stops the operation of the ultrasonic sensor 100 and controls the alarm operation control means. 29 is the second opening/closing detection means 1
When the cancel condition A or B is satisfied, the state of the device is left to the judgment of the initial state setting section 22. Once the return means 27 receives an open signal and then a close signal from the second opening/closing detection means 14 in the second alarm state, it returns the device from the second alarm state to the first alarm state. Further, the second alert state setting means 26 causes the notification lamp 9 to blink while the second alert status is being set.

Further, the operation control means 29 includes a first control section that operates all of the warning operation means 28, and a cut switch 7.
and a second control section that operates only the second control section. That is, when the trigger signal for activation is inputted in the first or second alert state, the first control unit starts the time T set by the second timer 32 (for example, 5 minutes) from that point on.
Only the horn 6.7 and the flasher light 8 are activated, which is the 11th warning. In this case, once the actuation trigger signal is manually input, the set time T will continue even if the trigger signal is no longer input.

All of the warning activation means 28 are activated, and the count value of this set time 'r is restarted from zero each time the trigger signal is input again.

On the other hand, the second control section releases the operation of the horn 6 and the flasher light 8 after the count of the set time T is completed, and sets the second alarm operation state in which only the cut switch 7 is operated. Also, even when this second control section is working,
When the trigger signal is input again, the operation control means 29
will be shifted to the operating state by the first control section.

Further, the operation control means 29 includes the second opening/closing detection means 14
When a close signal is output from the second key detection means 17 and an on signal is output from the second key detection means 17 (cancellation condition C), or when the above-mentioned cancellation condition A is satisfied, the state of the apparatus is left to the initial state setting section 22 to determine. Further, the operation control means 29 causes the notification lamp 9 to blink when the warning operation means 28 is activated.

The notification lamp 9 is connected to the first and second key detection means 1.
6. When an on signal is output from at least one of the devices 17, the device lights up regardless of the state of the device.

The control flow of this embodiment configured as described above is shown in FIG.

First, if at least one of the engine key switch 2I and the ignition (IG) switch 20 is on, the system is in a released state, and if both are off and the opening/closing bodies 3 to 5 are all closed, the system is in the initial state. Then,
If at least one of them is open, the first alert preparation state is entered (step sl).

St).

Next, when the first alert preparation state is reached, if the first opening/closing body 3 is opened by operating the lock knob, the buzzer IO sounds (steps SS, S4).

In other words, when the above-mentioned release state passes through the initial state and transitions to the first warning preparation state, the opening of the first opening/closing body 3 from the passenger compartment makes it presumed that the occupant will leave the vehicle l, and the buzzer is activated. 10 will prompt the occupant to perform an operation to shift to the alert state. Then, it is confirmed that the key switch 21 or the ignition switch 20 is not turned on, that only one of the first opening/closing bodies 3.3 is open, and that all other opening/closing bodies are closed or locked. If the first key detecting means 16 remains off and there is a lock signal from the lock detecting means 18 and a closing signal from the first opening/closing detecting means 3 for the first opening/closing body 3 which is opened, that is, keyless locking is performed. Then, the second alert preparation deafness occurs (steps S, ~S?).

In the second alert preparation state, the operation of the first timer 31 and the notification lamp 9 is started (step Sa,
S*). Then, the time T set by the first timer 31,
, at least one of the engine key switch 21, the first key detection means 16, and the second key detection means 17 is on (key detection), or the i-th to third opening/closing bodies 3 to 5
If at least one of the above is open, the notification lamp 9 is turned off and returns to the initial state. If not, the buzzer 10 is first sounded after the set time Lfl has elapsed, and the ultrasonic sensor lOO and theft detection means 115 are each turned on. and moves to the first alert state (step S, ~5tS).

In the first warning state, the notification lamp 9 is flashed, and the activation trigger (at least one of the first to third opening/closing bodies 3 to 5 without an ON signal from the first and second key detection means 16.17) is activated. If there is an open signal (lock release signal from the ignition switch 20 or a signal from the ignition switch 20), the second timer 32
The controller starts operating (turns on) and enters the first alarm operating state (steps S Ill to S1.). That is, the operation cut switch 7 of the pawn 6 is operated (cutting off the power supply to the starter) and the flasher light 8 is operated.

On the other hand, the above step Sl? When there is no activation trigger signal input, the first key detection means 16 does not detect a key (cancellation condition A), and the ignition switch 2 is activated after the key switch 21 detects the engine key.
If 0 is not turned on (cancellation condition B) and the second key detection means 17 detects the key, confirm that the second opening/closing body (back door) 4 is opened and only the ultrasonic sensor 100 is turned off. Then enters the second alert state (step S,.~
S.

4). When the above cancellation condition A or B is satisfied, the notification lamp 9 is turned off and the judgment system returns to the initial state of the work (step S□).If the second key is not detected in step Stt, the above-mentioned first Return to alert state.

In the second warning state, if there is a closing signal from the second opening/closing body 4, the state returns to the first warning state (step S).

. ), if this closing signal is not present, the presence or absence of other activation trigger signals other than the signal for the second opening/closing body 4 is checked (step S, 7). If there is no activation trigger signal, the second alarm state is continued, and if there is, the second timer 32 is activated and the first alarm operation state is entered (steps Sl?→S, .→5
ta).

In the above-mentioned first warning activation state, the cancellation condition A or C is met, that is, the first key detection means 16 detects a key, or the second opening/closing body 4 is open and the second key detection means 17 detects a key. If there is a detection, the operation of the warning activation means 28 is stopped, the notification lamp 9 is turned off, and the judgment system returns to the initial state (step S*s- to 5t5). If the above cancellation conditions A or C are not satisfied, the set time T
, and if the activation trigger signal is input again before the elapse of time, the operation of the second timer 32 is restarted from zero and the first alarm activation state is continued (step 5at=S *3
= S + aS + s), and when the set time T has elapsed, the second alert activation state is entered (step S, 4). That is,
The operation of the horn 6 and flasher light 8 is stopped, and only the cut switch 7 is allowed to continue operating.

Then, in the second warning activation state, cancellation condition A (step S*s) or C (step S3
a+S 3? ) is satisfied, the operation of the warning activation means 28 and the notification lamp 9 is stopped and the judgment system returns to the initial state. If the above-mentioned cancellation condition is not satisfied and the activation trigger signal is re-manufactured, the second timer is activated. 32 is restarted and the state shifts to the first alert operating state (step S, 8).

Therefore, in the vehicle anti-theft device according to the above embodiment, when the occupant locks all the first opening/closing bodies 3 to 5 in the closed state and leaves the vehicle l, one of the first opening/closing bodies 3 is locked last. When the door is closed with the keyless door lock, the first alert state occurs with the activation of the ultrasonic sensor 100 as described above.
When the second opening/closing body (back door) 4 is opened using the key in this state, the operation of the ultrasonic sensor loO is stopped and the state shifts to the second alarm state, and at least the alarm state itself is not canceled. Become. Therefore, even in this state, the theft detection means 115 is in operation.

That is, when the second opening/closing body (back door) 4 is first opened, the ultrasonic sensor 100 does not operate, but the occupant is in the vehicle!
Even if a thief enters the vehicle interior through the opening of the second opening/closing body (back door) 4 and tries to start the engine without the key while the thief is away from the ignition switch 20, the ignition switch 20
When the vehicle is turned on, the common pawn 6, flash light 8, and cut switch 7 are activated, making it impossible to start the engine and alerting the surrounding area that a thief has entered the vehicle compartment. In addition, even if an attempt is made to move by tow truck without starting the engine in this state, the theft detection means 115 is activated by the output of the wheel speed 110F, I I O)'1, drives the horn 6, etc., and issues an alarm. emanate.

Further, when in the first alert state, even if a thief forcibly removes the key cylinder of the second opening/closing body (back door) 4, turns on the second key detection means 17, and opens the second opening/closing body 4, the second opening/closing body (back door) Since the alert state is maintained, the vehicle l will be protected from theft.

Furthermore, even if the occupant enters the second alarm state himself, the vehicle automatically returns to the first alarm state by closing the second opening/closing body, so there is no need to perform a keyless lock to enter the alarm state again.

Furthermore, in the case of this embodiment, in addition to the anti-theft measures by operating the various operation parts as described above, a signal for detecting the rotation of the wheels is output from the wheel speed sensors 110F' and 11OR under the second warning state described above. In this case, the theft detection signal is input to the operation control means 29 via the theft detection means 115 as described above. Therefore, unlike the case described above, even if the vehicle is transported by tow truck without any operation of the vehicle's operating parts, opening/closing body, etc., as described above, of course, the pawn 6 It is possible to activate various alarm devices such as a flasher light 8 or the like. Therefore, it is extremely effective as a theft prevention device for tow trucks and the like.

In addition, this configuration is not only an anti-theft measure; for example, if the second alarm state is set according to a predetermined procedure, it will be possible for a vehicle without a driver to accidentally start driving when parked on a slope. It will also function effectively as a means of alerting the surroundings of danger in such situations.

In the above embodiment, the back door of a hatchback vehicle was selected as the second opening/closing body, but the opening/closing body may also be a trunk lid, and one side door may be the first opening/closing body.
The other is the second opening/closing body, or in the case of a four-door vehicle, the front door is the first opening/closing body and the rear door is the second opening/closing body. They can be freely selected as appropriate.

Further, in the above embodiment, removing the engine key is one of the conditions for the anti-theft device to enter the initial state, but instead of removing the engine key, the condition for the initial state may be that the vehicle speed drops below a certain speed. You can also do it.

In addition, FIG. 5 shows the wheel speed sensor t as described above, if necessary.
This is a tow truck movement detection device used in combination with I OF', l t on, and this configuration utilizes the fact that the damper rod 121 of the suspension damper 120 moves up and down due to the expansion and contraction of the suspension when the vehicle moves. A theft detection system is formed by attaching a magnet 122 to the tip of a damper rod 121 as shown in FIG. Therefore, as in the case described above, under the second alert state, the reed switch 124 is turned off for a certain period of time or more.
If it is N, it is determined that the vehicle is being transported by a tow truck, and various warning means such as the horn 6 and flasher light 8 can be activated based on the determination signal. If this is done, double detection means will be provided after all, and if the wheel speed sensor 11
Even if 0F, l10R is out of order, the anti-theft function can be maintained reliably.
