Absence detecting means 2 detects that the ignition switch has been turned off, that the key has been removed from the ignition key cylinder, that the door is closed, and that the trunk is closed. Based on the detection that the engine hood is closed and the door being locked from the outside, the AND logic of each detection recognizes that the regular occupant of the vehicle is away from the vehicle and outputs the absence signal. Generates a detection signal that becomes This detection signal does not occur unless the above AND logic is established. The generated detection signal is transferred to the controller 4. Detection that the ignition switch has been turned off is made by the ignition off detection switch built into the ignition key cylinder, and detection that the door is closed is provided between the door and the door opening of the vehicle body. The door switch is used to detect that the trunk is closed, and the trunk switch that is provided between the trunk lid and the trunk lid opening of the vehicle body detects that the engine hood is closed. The hood switch provided between the ridge panel and the ridge panel detects the door being locked from the outside by an outside key lock switch built in a door key cylinder attached to the door.

To detect when the hood of the engine is open, when the windshield is broken, when the tire is removed, and when the audio in the car is removed. On the basis of any of the detections, it is recognized that a non-steady-state action is being performed, and a detection signal which is a non-steady-state action signal is generated. The generated detection signal is transferred to the controller 4. The detection that the key cylinder of the door is broken is made by the cylinder switch built in the door key cylinder attached to the door, and the detection that the key cylinder of the trunk is broken is built in the key cylinder of the trunk. A trunk key cylinder switch is used to detect that the door is open, and a door switch provided between the door and the door opening of the vehicle body is used to detect that the trunk is open. It is made by the trunk switch provided between the opening of the trunk lid and the detection of the opening of the engine hood is made by the hood switch provided between the hood and the hood ridge panel, which destroys the windshield. Detection of being done is a windshield The wind glass presence detection sensor mounted on the vehicle body side detects that the tire has been removed by the tire sensor mounted between the wheel of the tire and the vehicle body, and the audio inside the vehicle has been removed. Is detected by, for example, an audio presence detection sensor mounted between the CD player and the console.

On the other hand, the mode setting means 8 provided in the controller 4 determines whether the mode is the theft warning mode or the theft warning cancellation mode, and sets based on the result of the judgment. The mode setting means 8 sets the theft warning mode when there is a detection signal transferred from the absence detection means 2, and sets the theft warning cancellation mode when there is no detection signal from the absence detection means 2. The theft warning mode and the theft warning cancel mode set by the mode setting means 8 are recognized by the warning signal output means 10 also provided in the controller 4.

The discriminating means 9 provided in the controller 4 discriminates the presence or absence of the detection signal from the non-steady-state action detecting means 3, and if the non-steady-state action detecting means 3 determines that there is a detection signal, the non-steady-state action is detected. Generate a discrimination signal. This unsteady behavior discrimination signal is recognized by the alarm signal output means 10 also provided in the controller 4.

The alarm signal output means 10 is a mode setting means 8
Has a timer for determining whether the unsteady behavior discrimination signal from the discrimination means 9 is the first time or the second time or later when the anti-theft behavior mode is set. The first alarm signal is generated when it is recognized that it is the first time, and the second alarm signal is recognized when the unsteady action determination signal is recognized by the timer after the second time.
The alarm signal of is generated. The first alarm signal and the second alarm signal generated by the alarm signal output means 10 are recognized by the antitheft output means 11 provided in the controller 4.

The anti-theft output means 11 provided in the controller 4 recognizes the first alarm signal and the second alarm signal generated by the alarm signal output means 10. When there is a first alarm signal generated by the alarm signal output means 10, the first
The first anti-theft output is generated based on the alarm signal and the second alarm signal generated by the alarm signal output means 10 generates the second anti-theft output based on the second alarm signal.
The first anti-theft output generated by the anti-theft output means 11 is transferred to the traveling prevention means 5 and the first alarm means 6
The second antitheft output generated by the antitheft output means 11 is also transferred to the second alarm means 7.

Here, the traveling prevention means 5 is a switch provided in the starter circuit of the engine, and the traveling prevention means 5 is the first anti-theft output means 11 which generates the antitheft output means 11.
When a current is supplied by the anti-theft output of the above, the switch is turned on and the switch is opened. Therefore, the starter circuit is cut off to make the starter motor non-rotating so that the engine cannot be started.

The first alarm means 6 is an antitheft output means 1
1 is turned on when a current is supplied by the first anti-theft output generated, the function of turning on a vehicle lighting device such as a headlight, a taillight, and an interior light and driving a buzzer arranged in the vehicle interior is provided. Have. Since lighting of the vehicle lighting device and driving of the buzzer are intermittently performed within a predetermined time T when current is supplied, the lighting and the buzzer of the vehicle blink and drive through a predetermined intermittent rest time. To do.

The second alarm means 7 is the theft prevention output means 1
When a current is supplied by the second anti-theft output generated by No. 1, it has a function of being turned on to turn on a lighting device such as a headlight, a taillight, and an interior light, and at the same time operate a vehicle horn. Since the lighting device is turned on intermittently within a predetermined time T when a current is supplied, the lighting device blinks through a predetermined intermittent rest time, and the horn turns on a predetermined time T. Since it operates intermittently within, it resonates intermittently.

The vehicle antitheft device 1 having such a structure operates as shown in FIG.

When the ignition switch is turned off, the key is removed from the ignition key cylinder, the door is closed, the trunk is closed, the hood of the engine is closed, the door is locked from the outside, and the owner of the vehicle receives the time A.
When the vehicle is separated from the vehicle, the absence detecting means 2 generates a detection signal which is an absence signal. At time A, the absence detecting means 2 generates a detection signal, so that the mode setting means 8 in the controller 4 changes the setting from the warning release mode to the warning mode.

After that, at time B, the door key cylinder is destroyed or the trunk key cylinder is destroyed.
Unsteady behavior if the door is opened, the trunk is opened, the hood of the engine is opened, the windshield is destroyed, the tires are removed, or the audio in the car is removed. A detection signal is generated by the detection means 3 in order to recognize that an unsteady action is being performed.

A detection signal is generated by the non-steady-state action detection means 3, and the detection signal is transferred to the determination means 9 in the controller 4. Therefore, the determination means 9 generates the non-steady-state action determination signal, and the non-steady-state action determination is performed. The signal is an alarm signal output means 10
Be recognized by. At this time, the mode setting means 8 sets the theft warning mode, and it is recognized that the unsteady behavior determination signal from the determination means 9 is the first time, so the alarm signal output means 10 generates the first alarm signal. However, since the antitheft output generating means 11 generates the first antitheft output in response to the first alarm signal, the first antitheft output prevents the running preventing means 5 from shutting off the starter circuit and starting the engine. In addition, the first alarm means 6 causes the vehicle lighting and the buzzer arranged in the vehicle interior to blink for a time T through a predetermined intermittent rest time. Illumination of the vehicle blinks and the buzzer drives to prompt the exclusion of unsteady behavior to the vehicle and to visually display to regular occupants and other people that the vehicle is performing unsteady behavior. The alarm by the first alarm means 6 is automatically turned off after the time T has passed.

If the unsteady act on the vehicle is continued even at the time C after the time B, the detection signal by the unsteady act detection means 3 is continuously generated, and the detection signal is determined by the discrimination means 9. , The discrimination means 9 generates an unsteady behavior discrimination signal, the unsteady behavior discrimination signal is recognized by the warning signal output means 10, and the mode setting means 8 sets the anti-theft mode. Since it is recognized that the unsteady action discrimination signal from 9 is the second time, the alarm signal output means 10 generates a second alarm signal,
The antitheft output generation means 11 generates the second antitheft output by the second alarm signal, so the travel prevention means 5 keeps the starter circuit in the cutoff state by the second antitheft output and the second alarm means. 7 blinks the lighting device for a predetermined intermittent rest time, and intermittently activates the horn within a predetermined time T to cause the horn to ring intermittently. The lighting of the vehicle blinks and the horn sounds intermittently to help eliminate unsteady behavior on the vehicle and to visually and audibly inform the regular occupants and other people that the vehicle is performing unsteady behavior. To display. The alarm by the second alarm means 7 is automatically turned off after the time T has passed.

At time C, the second warning means 7 shuts off the starter circuit of the travel prevention means 5, blinks the lighting device for a predetermined intermittent down time, and intermittently blows the horn. When the non-steady-state action with respect to is not eliminated and the time reaches D, the detection signal by the non-steady-state action detection means 3 is continuously generated, and the detection signal is determined by the determination means 9.
, The discrimination means 9 generates an unsteady behavior discrimination signal, the unsteady behavior discrimination signal is recognized by the warning signal output means 10, and the mode setting means 8 sets the anti-theft mode. Since it is recognized that the unsteady behavior discrimination signal from 9 is the second or later, the alarm signal output means 10 generates the second alarm signal, and the antitheft output generation means 11 causes the second alarm signal. Since the second antitheft output is generated, the second antitheft output causes the travel prevention means 5 to keep the starter circuit in the cutoff state, and the second alarm means 7 sets the illumination device to a predetermined intermittent down time. The horn is flickered through and the horn is intermittently operated within a predetermined time T to intermittently ring the horn. The lighting of the vehicle blinks and the horn sounds intermittently to help eliminate unsteady behavior on the vehicle and to visually and audibly inform the regular occupants and other people that the vehicle is performing unsteady behavior. To display. The alarm by the second alarm means 7 is automatically turned off after the time T has passed.

When the unsteady action on the vehicle is continued from time B through time C and time D, at time B, the running prevention means 5 prevents the engine from starting and the first warning means 6 causes the vehicle to start. A visual warning is given by lighting, and at time C and time D, the second warning means 7 keeps the engine from being started by the travel blocking means 5, and the second warning means 7 illuminates the vehicle visually and audibly. An alarm is given.

At time E after time D, when the door is unlocked from the outside by the regular occupant of the vehicle and the detection signal from the absence detecting means 2 stops, the mode setting means 8 in the controller 4 becomes alert. The alarm release mode is set from the mode, and the first antitheft output from the antitheft output generating means 11 is set to the second without outputting the first alarm signal and the second alarm signal from the alarm signal output means 10. Since the anti-theft output is not generated, the traveling prevention means 5 stops the interruption of the starter circuit and allows the engine start by the regular passenger.

FIG. 3 and FIG. 4 show another embodiment of the vehicle antitheft device according to the present invention.

The vehicle anti-theft device 1 in this case is provided with a start blocking means 5a and a transmission lock means 5b in the travel blocking means 5, and other parts are similar to those of the embodiment shown in FIG. There is. The starting cut means 5a has a function of turning on when a current is supplied by the first antitheft output based on the first alarm signal and cutting the current to the starter relay circuit of the engine. The starting cut means 5a can be turned on by the supply of electric current to cut off the supply of fuel to the fuel pump and electric current to the ignition system of the engine. The transmission lock means 5b is turned on when a current is supplied by the first antitheft output based on the first alarm signal, and locks the selector of the automatic transmission in the stationary position of the vehicle which is the parking position. The starting cut means 5a and the transmission lock means 5b continue to be turned on while the warning mode is set by the mode setting means 8, and turned off when the warning mode is changed to the warning release mode.

In this case, if there is an unsteady action on the vehicle from time A to time B and time C in FIG. 4, a detection signal is generated by the unsteady action detection means 3 at time A, and the detection signal is Since it is transferred to the discrimination means 9 in the controller 4, the discrimination means 9 generates an unsteady behavior discrimination signal, and the unsteady behavior discrimination signal is the alarm signal output means 10.
Is recognized by the mode setting means 8 to set the anti-theft mode, and it is recognized that the unsteady behavior discrimination signal from the discrimination means 9 is the first time. Therefore, the alarm signal output means 1
0 generates a first alarm signal, and the anti-theft output generating means 11 generates a first anti-theft output in response to the first alarm signal, so that the starting cut means 5a outputs the first alarm signal based on the first alarm signal. The current to the starter circuit of the engine is cut by the current supplied by the anti-theft output of the engine, and the transmission lock means 5b supplies the current of the first anti-theft output based on the first alarm signal to the automatic transmission selector to the parking position. At the same time, the first alarm means 6 blinks the illumination of the vehicle to prompt the exclusion of the non-steady-state action on the vehicle, and confirms that the non-steady-state action is performed on the vehicle for the regular occupants and other persons. Display visually.

If the non-steady-state action is not excluded even at the time B after the time A or at the time C after that, it is recognized that the non-steady-state action determination signal is the second time or later, and the alarm signal is output. The second alarm signal from the means 10 causes the anti-theft output generation means 11 to generate a second anti-theft output so that the second alarm means 7 illuminates the vehicle and the horn provides a visual and audible alarm. .

After time C, the door is unlocked from the outside by the regular occupant of the vehicle, and the absence detecting means 2
When the detection signal is no longer generated, the mode setting means 8 in the controller 4 changes the warning mode to the warning cancellation mode, and neither the first warning signal nor the second warning signal from the warning signal output means 10 is generated. Without the theft prevention output generating means 11
Since neither the first anti-theft output nor the second anti-theft output from the vehicle is generated, the traveling prevention means 5 stops the interruption of the starter circuit and allows the engine start by the regular passenger.

FIG. 5 and FIG. 6 show still another embodiment of the vehicle antitheft device according to the present invention.

The vehicle anti-theft device 1 in this case is provided with the hood lock means 13 and the controller 4 with the hood lock output means 12.
The hood lock means 13 has a function of being turned on when a current is supplied so that the lock mail attached to the hood cannot be unlocked from the lock mail attached to the vehicle body. The hood lock output means 12 has a function of generating an antitheft output at the same time when the antitheft mode is set by the mode setting means 8 and transferring the generated antitheft output to the hood lock output means 13. Therefore, when the mode setting unit 8 sets the anti-theft alarm mode to the anti-theft mode, the hood lock output unit 12 generates an anti-theft output, and the hood lock unit 13 sends the lock mail of the hood to the lock fee on the vehicle body side. The hood cannot be opened by the hood lock release lever from inside the room because the email cannot be unlocked, and the hood cannot be opened to connect the battery power directly to the starter motor, preventing the engine from starting. It

In this case, when there is an unsteady action on the vehicle from time A to time B and time C in FIG. 6, a detection signal is generated by the unsteady action detection means 3 at time A, and the detection signal is Since it is transferred to the discrimination means 9 in the controller 4, the discrimination means 9 generates an unsteady behavior discrimination signal, and the unsteady behavior discrimination signal is the alarm signal output means 10.
The hood lock output means 12 generates an anti-theft output because the mode setting means 8 sets the anti-theft mode by the hood lock output means 13. Recognizing that the lock mail of the hood cannot be unlocked with respect to the lock fee mail on the vehicle body side, the mode setting means 8 sets the anti-theft mode, and the unsteady behavior determination signal from the determination means 9 is the first time. Therefore, the alarm signal output means 10 generates a first alarm signal,
Since the antitheft output generating means 11 generates the first antitheft output in response to the first alarm signal, the travel preventing means 5 sets the starter circuit in the cutoff state to prevent the engine from starting, and the first alarm means. 6 blinks the vehicle lights to visually indicate to the vehicle that an unsteady behavior is occurring. The starting cut means 5a cuts the current to the starter circuit of the engine by supplying the current by the first anti-theft output based on the first alarm signal, and the transmission lock means 5b controls the first alarm signal based on the first alarm signal. The selector of the automatic transmission is locked in the parking position by supplying current with the anti-theft output. Since the non-steady-state action detection signal from the non-steady-state action detecting means 3 is generated by the mode setting means 8 until the warning mode is changed to the warning release mode, the starting cut means 5a continues to cut the electric current to the starter circuit of the engine and the transmission. Locking means 5
In b, the selector of the automatic transmission is kept locked in the parking position, and when the mode setting means 8 sets the warning release mode from the warning mode, the starting cut means 5a stops the cutting of the current to the starter relay circuit of the engine, and the transmission locks. Means 5b unlocks the selector of the automatic transmission.

If the non-steady-state action is not excluded even at the time B after the time A or at the time C after that, it is recognized that the non-steady-state action determination signal is the second time or later, and an alarm signal is output. The second alarm signal from the means 10 causes the anti-theft output generation means 11 to generate a second anti-theft output so that the second alarm means 7 illuminates the vehicle and the horn provides a visual and audible alarm. .

After the time C, the door is unlocked from the outside by the regular occupant of the vehicle, the hood and the trunk of the engine are closed, and the door is closed. The key is inserted into the ignition key cylinder, and the ignition key is inserted. When the switch is turned on, no detection signal is generated from the absence detecting means 2, so the controller 4
The mode setting means 8 therein changes the setting of the warning mode to the warning release mode, and neither the first warning signal nor the second warning signal from the warning signal output means 10 is generated and the anti-theft output generation means 11 outputs the first warning signal. Since neither the first anti-theft output nor the second anti-theft output is generated, the traveling blocking means 5 stops the interruption of the starter circuit and allows the engine start by the regular passenger.

[0037]

As described above, since the vehicle antitheft device according to the present invention has the above-mentioned structure,
If there is an unsteady action on the vehicle while the regular occupant of the vehicle is away from the vehicle, the vehicle is initially blocked by the traveling blocking means and the lighting device of the vehicle is illuminated by the first warning means. If the unsteady behavior continues, the traveling prevention means turns on the illumination device of the vehicle while the vehicle is in the traveling blocked state, and the horn of the vehicle is activated. Will give an alarm when the horn is not sounding and will prompt the exclusion of non-steady-state actions only with a visual alarm.If the non-steady-state actions are not stopped, the horn will also be added to alert. , At first, a visual alert is given to prevent noise to the surroundings, and if a non-steady-state action is continued, an unsteady action is given by adding an audible alarm in addition to a visual alert. In which an excellent effect that it is possible to prompt the excluded who are Tsu.
