Abstract

PURPOSE:To surely protect a vehicle from theft by having a driver's seat operate to protect accessories of the vehicle and locking said seat in the inoperable state if a man enters the vehicle by an unfair means. CONSTITUTION:When a vehicle is parked, that is, the vehicle is held stationary and all doors are kept locked, a driver's seat driving device 3 is driven by the output of an electronic controller 5 to slide the driver's seat 1 until the seat reaches a point of a theft-proof pattern. The pattern is the state where the driver's seat 1 is slided to the most forward position and the seat back 1A thereof is inclined to the maximum. The controller 5 then determines whether some unfair behavior has been down on the vehicle or not. If the controller 5 identifies the unfair behavior, a theft-proof alarm will be given, namely, the controller 5 has a front lamp flash and a klaxon sound. When a driver goes back to the vehicle and inputs releasing data by the operation through a ten-key 10, such theft-proof system can be released. And then the vehicle will be returned to the normal state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle theft prevention device that protects a vehicle from theft while the vehicle is parked or stopped.

[Prior Art] Conventionally, when a legitimate owner of a vehicle, such as a driver, leaves the vehicle while the vehicle is stopped, it has been common practice to lock the vehicle's doors to prevent theft.

However, there have been many reports of cases in which the locked door is opened using some method and the vehicle is stolen.

Therefore, a so-called vehicle theft prevention device has been proposed, which adds a new configuration to the vehicle that makes it impossible to drive, and when the legal owner of the vehicle inputs special cancellation data, the operation is canceled and the vehicle can be driven. has been done.

[Problems to be Solved by the Invention] However, the above-mentioned vehicle theft prevention device has the following problems and is still not satisfactory.

That is, the IIJm system is concentrated on the front panel in front of the driver's seat and under his feet so that the driver can easily operate all the equipment of the vehicle, thereby improving operability. Vehicle anti-theft devices are no exception, especially in systems using microcomputers that have become mainstream in recent years, as the CPU part, which is susceptible to heat and mechanical vibration, is located near the vehicle interior, making it difficult to centralize control near the driver's seat. This is even more noticeable.

Therefore, once the door of the vehicle is opened by illegal means and the driver gets into the driver's seat, there is a possibility that the control system may be destroyed and the operation of the vehicle anti-theft device may be stopped, leading to theft.

Moreover, once the vehicle is boarded, it cannot be discovered from the outside even if the worker crawls under the driver's seat to perform work.
Unauthorized intruders could carry out destructive work over a long period of time, which was extremely inconvenient.

[Object of the invention] The present invention has been made to solve the above problems,
A 1F vehicle theft prevention device that can more completely prevent vehicle theft by protecting the control system of equipment including the vehicle theft prevention device from destruction, even if the vehicle is illegally infiltrated by some method. Its purpose is to provide.

[Means for Solving the Problems] The configuration of the present invention to achieve the above object, as shown in the basic configuration diagram in FIG. A driver seat locking means (■) that locks when the driver is unable to drive, a release data input means (2), and a lock that releases the operation of the driver's seat locking means when the release data from the release data input means (■) is predetermined. The gist of the present invention is a vehicle theft prevention device characterized by comprising: a release means IV;

[Function] The driver's seat lock means of the present invention is a device that covers various devices installed near the front panel or under the driver's seat, whose position and shape are variable, so that they cannot be manipulated or destroyed. This locks the driver's seat so that it does not return to its normal drivable state. Therefore, the rotation of the electric motor is transmitted to the seat via the four-wheel drive mechanism and the seat is moved. In the case of a so-called power seat, the seat is pulled as far forward as possible to prevent pressure from getting under the driver's seat, and a reclining mechanism is used to tilt the seat back as far forward as possible to cover the front panel and steering wheel. This effect can be achieved by separating the driver's seat, which makes it impossible to operate the steering wheel, from a power mechanism such as an electric motor.

The release data input means is used to input information for unlocking the driver's seat lock means. Therefore, techniques such as a release switch hidden inside the vehicle or combination input from a numeric keypad are used.

Further, the lock release means determines whether the input from the release data input means is a predetermined one, and
When it is determined that it is the designated seat, the driver's seat 1 mentioned above
This makes it possible to release the lock of the locking means and return the driver's seat to its normal state.

That is, the locked state of the driver's seat is released only when the rightful owner of the vehicle inputs a release command. Therefore, as mentioned above, if the release data input means is a hidden switch installed inside the vehicle, it is determined that only the legitimate right holder can operate the switch, and if the combination signal is from the numeric keypad, the combination is When it is a predetermined item, it determines that the user is the rightful owner and releases the lock.

EXAMPLES Hereinafter, in order to explain the present invention more specifically, the present invention will be described in detail with reference to Examples.

[Example] FIG. 2 shows a perspective view of a vehicle equipped with a vehicle anti-theft device according to an example.

It is composed of door lock key operation confirmation switches 11B and 13B1 and door lock operation confirmation switches 11G and 13C.

It should be noted that each of the above [J's] is configured to receive power directly from the valve holder without going through an ignition switch so that it can be operated even after the ignition key is turned off.

FIG. 3 is an explanatory diagram of the driver seat drive device 3, and FIG. 3(A) is a perspective explanatory diagram thereof. As shown in the figure, this device is comprised of four electric motors 3A, 3B, 3C, and 3D and a transmission system that transmits their rotational force to the driver's seat 1. In the figure, 3A represents a reclining electric motor for tilting the seat back 1Δ of the driver's seat 1 forward and backward as shown in Figure (B), and 3A-1 represents its transmission mechanism consisting of gears.

3B is a rear vertical adjuster electric motor that moves only the rear end of the driver's seat 1 up and down as shown in FIG.
3B-2 is the torque cable, 3B-2 is the worm gear housing that is the transmission mechanism, and 30 is the electric motor for the front vertical adjuster that moves only the front end of the driver's seat 1 up and down as shown in (D). 1 indicates its torque cable, and 30-2 indicates a worm gear housing. Further, by driving these two electric motors 13B and 3G in synchronization, the entire driver's seat 1 can be moved up and down as shown in FIG. 3D is the seat slide Kawagiri ff1lJIfi to slide the driver's seat 1 back and forth as shown in figure (F), and 3D-1 is the torque cable.
3D-2 represents the worm gear housing.

Further, each worm gear housing is provided with a driver seat position sensor 3E that detects the movement state of the driver seat 1 by detecting the rotational speed of the worm gear.

By appropriately driving the four electric IJIs 3A, 3B, 3C and 3D mentioned above, the driver's seat 1 can be moved and adjusted as desired. The electronic control device 5 shown in FIG. 2 is responsible for appropriately driving this electric motor.
Electric power is supplied to the electric motor by a drive switch 7 disposed below the side surface of the motor and by a control program to be described later.

The three switches in the switch group 11.13 attached to the two doors perform the following switch operations.

First, what are the courtesy lamp switches 11A and 13A?
This is to turn on the courtesy lamp attached to the door only when the door is opened, and when the door is opened, the rO
NJ state, when closed it becomes rOFFJ state.

The door lock key operation confirmation switches 11B and 13B are for determining whether or not the key for executing the door lock operation has been inserted into the keyhole of the door and turned, and the door has been unlocked using the key. When it is in the rONJ state, it is in the rOFFJ state when locked or in the neutral position. This switch is provided to distinguish between a simple locking operation in which the door is locked without using a key and a locking operation using a key when locking the door.

The door lock operation confirmation switches '11c and 13C are switches that determine whether the door is locked or not.
rONJ state when unlocked, ro'F' when locked
It is configured to be in the FJ state.

FIG. 4 shows a block diagram of the control system of the vehicle anti-theft device of this embodiment. As shown in the figure, the electronic control unit @5 has an input port 5A that receives signals from two switch groups 11 and 13, a driver seat position sensor 3E, a numeric keypad 10, and a drive switch 7, and outputs a drive signal to the driver seat drive device 3. It is composed of two ports of an output port 5B, a ROM 5C1 that stores a control program (to be described later), a CPJ5D that executes information processing according to the control program, and a RAM 5E that temporarily stores information.

The vehicle anti-theft device of this embodiment configured as described above executes processing according to the control program shown in FIG.

The processing of each step of the theft prevention routine, which is the control program shown in FIG. 5, will be explained below.

This routine is interrupted by the CPU 5D at predetermined intervals, and the CPU 5D
, step 100 is executed first.

Step 100 is a step for determining whether or not the internal combustion engine, which is the drive source of the vehicle, has stopped operating. If it is detected that the ignition key has been turned OFF, the process moves to the next step 110, and the ignition key is still in the C position. )FF
If the status is not the same, this step is repeatedly executed.

In step 110, the door on the passenger seat side is locked, and the door lock operation confirmation switch 11C on the driver seat side
1 has changed from the "ON" state to the rOFFJ state. That is, if the driver's door is closed last after all doors have been locked without a key, the process continues to put the driver's seat into the anti-theft pattern as described below, and if it is not Step 10
It returns to 0.

Step 120 is a step for determining whether or not the doors on the driver's and passenger's seats are securely closed. If the courtesy lamps of all the doors are off, the process proceeds to step 130. When the door is opened, the light shines under your feet! For l-, the courtesy lamp switch 11A or 13A is rO.
If the door is closed after exiting the vehicle, the switch will be in the 0FFJ state, so this switch must be turned OFF.
It judges the state. With the above steps, all doors are locked, the driver exits the vehicle, and
When it is determined that all doors are closed, proceed to the next step 13.
0 is executed, otherwise step 10 is executed as described above.
Return to 0.

Step 130 moves the driver's seat 1 into an anti-theft pattern to prevent the vehicle from being stolen.

In other words, since the vehicle was stopped and all doors were locked, and the driver's side door was opened and then closed, it is determined that the driver exited the vehicle after locking all doors. . When it is detected that the vehicle has entered the parking state in this manner, the CPU 5D outputs an output to the driver's seat drive device 3 via the output boat 5B, and moves the driver's seat rM1 until the theft prevention pattern is reached. Here, the anti-theft pattern is a state of movement of the driver's seat 1 that is stored in advance in the ROM 5C, and refers to a state in which the driver's seat 1 is moved furthest forward and the seat back 1A is tilted forward as much as possible. CPLJ5D continues to output until this state is reached, and the detection result of driver seat position sensor 3E becomes RO.
When it becomes the same as the anti-theft pattern stored in the M5C, its output is stopped.

When the movement of the driver's seat 1 is completed in this manner, the next step 140 is executed, and it is determined whether the door lock key operation confirmation switch is in the rONJ state.

That is, it is determined whether the driver returned to the vehicle and unlocked it using the key. When it is determined in this step that the door is unlocked by the key, the next step 150 is executed to return the driver's seat 1 to the normal pattern. Here, the normal pattern is the ROM
This is the most suitable position of the driver's seat 1 for the driver to drive the vehicle, which is stored in the ROM 5C, and the CPU 5D drives the driver's seat until the output of the driver's seat position sensor 3E becomes the same as the normal pattern in the ROM 5C. The operation is completed by continuing to output to device 3.

On the other hand, if it is determined in step 140 that the door lock has not yet been unlocked with the key, that is, that the driver has not yet returned to the vehicle, step 200 is executed.

In step 200, it is determined whether the door lock is released or not based on the operating state of the door lock operation confirmation switch 11C113C. If the door is unlocked here, it is assumed that it was not done with the key in the previous step 140, but by some illegal means, and the next step 210 is skipped and the process proceeds to step 22.
0 is executed, otherwise the process moves to step 210.

In step 210, the courtesy lamp switch 11A,
It is determined whether or not 13A has changed from the OFF state to the ON state, that is, whether the door has been opened. here,
If the judgment is true, it means that the door was pounded with the same number even though the door lock was not released, so proceed to the next step 2.
Otherwise, the process returns to step 130 and repeats the above steps. ``Step 220 is executed when some kind of illegal act is committed against the vehicle as described above, and an anti-theft alarm is executed. This warning is, for example, by flashing the headlights or sounding the horn to notify the driver that someone has committed an illegal act against the vehicle.

In the following step 230T-, it is determined whether release data has been input using the numeric keypad 10 or not.

That is, if the vehicle anti-theft alarm is executed and the driver inputs the return release data, the CP goes to step 150 described above.
As the execution of U5D progresses, the anti-theft system is canceled and the normal state is restored. Otherwise, the process returns to step 220 and the anti-theft alarm is executed.

The vehicle anti-theft device of this embodiment configured and operated as described above has the following effects.

First, the driver's seat 1 of the vehicle is moved to the anti-theft pattern to prevent the vehicle from being stolen, so even if someone illegally enters the vehicle, the anti-theft device must be deactivated. This is impossible because the front panel and steering wheel that control the vehicle's equipment, including this device, are covered and protected by the driver's seat 1.

In addition, even if the power supply line of the battery that supplies power to all the equipment is cut before entering the vehicle, the driver's seat 1 that has been moved to the anti-theft pattern will be moved by the electric IJ machine via the worm gear. Since it is impossible to move the vehicle manually unless the vehicle is intruded, it is impossible to carry out any other work after the vehicle has entered the vehicle. It is impossible to drive on the road.

Furthermore, although the device perfectly protects the vehicle from theft in all cases, the driver does not feel any trouble in operating it. That is, when the operation of the internal combustion engine is stopped and all the doors are locked, and the driver closes the door on the driver's seat side, it is automatically determined that the vehicle is parked, and the driver's seat 1 adopts the anti-theft pattern. As long as the driver returns to the vehicle and unlocks the door with the key, the driver's seat 11 automatically returns to the normal pattern.

Therefore, the driver only needs to operate the numeric keypad 10 when there is an unauthorized intrusion into the vehicle; otherwise, theft can be prevented without any special operation.

In this embodiment, only the driver's seat was controlled, but it would be more effective if the passenger's seat was also controlled at the same time.

[Effects of the Invention] As described above in detail with reference to the embodiments, the vehicle anti-theft device of the present invention is characterized in that it prevents theft by locking the driver's seat in a drivable state.

Therefore, even if someone infiltrates into the vehicle by some illegal means, the driver's seat acts to protect the vehicle's equipment, preventing the intruder from carrying out any other illegal operations. and.

This state can be easily restored to normal by inputting cancellation data that only the legal right holder of the vehicle, such as the driver, can know, so the legal right holder of the vehicle can completely steal the vehicle without having to feel the trouble of having to set up a separate vehicle. Prevention can be achieved.
