Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a so-called antitheft device for a vehicle for construction work, which is equipped with vehicle-mounted equipment such as a blade (earthwork board) and a backhoe (drag excavator).
[0002]
[Prior art]
Conventionally, in construction vehicles, an ignition switch consisting of a mechanical cylinder lock is provided in the drive power circuit from the power battery to open and close the drive power circuit so that the engine can be driven by those who do not have a unique cylinder key. It was prohibited.
[0003]
However, since the driving power supply wiring connected to the ignition switch is connected to the back of the ignition switch, it can be easily taken out. For this reason, if these drive power supply wirings are connected, the voltage from the power supply battery can be applied to the drive power supply circuit, and even the person who does not have a key unique to the vehicle can start driving the engine. I was able to steal.
[0004]
An engine start control device disclosed in, for example, Japanese Patent Application Laid-Open No. 61-229645 is a device for preventing theft of a vehicle by a person who does not have such a vehicle-specific key. This engine start control device holds a fuel supply means for supplying fuel to the engine, an electric driver for energizing the fuel supply means, a specific electronic code, compares the input code with this specific code, and matches. A control means for instructing the electric driver to energize, and a code input means for inputting an input code to the control means.
[0005]
According to this engine start control device, in addition to the operation of the ignition switch, if the specific code is not input from the code input means, the control means does not instruct the electric driver to energize, and as a result, the fuel supply means is not driven. The fuel is not supplied to the engine. As a result, the engine can be prevented from being driven by short-circuiting the drive power supply wiring, and the vehicle can be prevented from being stolen.
[0006]
[Problems to be solved by the invention]
However, the above-described conventional engine start control device enables the engine to start when a specific code is input in addition to the ignition switch, but the drive control target is still the old engine only. However, although it takes more time than unauthorized connection of only the ignition switch, the engine can be driven by performing unauthorized connection to the fuel supply means. Since only the engine is subject to drive control, once the engine is started, all other on-vehicle equipment (blades, backhoes, etc.) other than the travel drive equipment can be operated, and there is no problem with travel. Since it was not given, theft was relatively easy, which was insufficient to reliably prevent theft.
[0007]
The present invention has been made in view of the above situation, and by making other vehicles mounted on the vehicle at the same time impossible to drive at the same time, even when only the engine is illegally driven, overall travel is restricted. An object of the present invention is to provide a vehicle theft prevention device that makes it difficult to steal a vehicle.
[0008]

[0009]
In this vehicle antitheft device, the on-vehicle equipment cannot be operated unless all the switching means (for example, relays) are illegally connected. If all the relays are illegally connected, extremely complicated work is involved. This effectively makes it impossible to drive the engine through unauthorized connection. Even if only the engine is in a drivable state, other on-vehicle equipment remains in an inoperable state, so that travel is restricted and the vehicle is reliably prevented from being stolen. Further, only when all of the switching means are operated, the closed contact during operation is closed, and when one or more of the arbitrary switching means is not operating, the starter motor cannot be started. As a result, the starting circuit and the starter motor are double-blocked, and it becomes more difficult to start the vehicle by unauthorized connection, and the vehicle is more reliably prevented from being stolen.
[0010]

[0014]
The vehicle antitheft device according to claim 4 is characterized in that the auxiliary input means is a radio wave type or infrared type remote control key.
[0015]
In this vehicle antitheft device, a unique electronic code is transmitted by radio or infrared using a remote control key and read into the control means without contact. Therefore, as in the case of the contact type name card, deterioration of the code reading performance due to wear is prevented, and the code signal transmission distance is also increased.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of a vehicle antitheft device according to the present invention will be described in detail with reference to the drawings.
[0017]
FIG. 1 is a block diagram showing a configuration of an embodiment of a vehicle antitheft device according to the present invention, and FIG. 2 is an explanation showing a vehicle equipped with the vehicle antitheft device and a vehicle-mounted device to be controlled mounted on the vehicle. FIG. 3 is a circuit diagram showing an example of a starter circuit blocking means.
[0018]
As shown in FIG. 2, the vehicle 1 for construction work includes various vehicle-mounted devices for driving assistance or work in addition to the driving motor 3 as the driving device. Examples of the vehicle-mounted device include an engine cut solenoid 5, a starter motor 7, an unload lever 9, a travel unload 11, a computer 13, and the like.
[0019]
In this example, the traveling motor 3 of the vehicle 1 is hydraulically driven. Further, the engine cut solenoid 5 is interposed in a fuel supply piping system that connects the fuel tank and the engine, and is opened during normal operation to enable fuel supply, but it is determined that fuel supply is not necessary. When the operation is stopped, that is, when the running is stopped, the fuel supply stop signal is received and the valve is closed to cut the fuel.
[0020]
The starter motor 7 starts the engine, and starts the engine by rotating a ring gear carved around the flywheel with a pinion (not shown) fixed to the output shaft. When the starter motor 7 is turned on, the pinion jumps out by the suction force of the magnetic switch and meshes with the flywheel. A current from a power supply battery is applied to the starter motor 7 via a starting circuit (not shown).
[0021]
The unload lever 9 is a safety lever for preventing accidents, and the boom 15 and the hydraulic system can be operated by lowering the unload lever 9. The passenger always operates the vehicle 1 with the unload lever 9 lowered. Therefore, the hydraulic system does not operate when the unload lever 9 is raised.
[0022]
The travel unload 11 sends hydraulic pressure to the travel motor 3 to drive the travel motor 3, and controls supply stop of hydraulic pressure by a solenoid.
[0023]
The computer 13 controls the operations of the above-described traveling device and vehicle-mounted device mounted on the vehicle 1.
[0024]
Further, the vehicle 1 is provided with an ignition switch 17 made of a mechanical cylinder lock similar to the conventional one. The ignition switch 17 can be opened and closed by operating only the unique cylinder key 17a.
[0025]
And the vehicle antitheft device 21 as shown in FIG. 1 is mounted on the vehicle 1 provided with the above-described travel drive device, various travel-mounted devices for driving assistance, or work. The vehicle antitheft device 21 includes a name card holder / power switch (hereinafter abbreviated as a card holder) 23 as auxiliary input means, a password input device 25 as key input means, and a relay as switching means. A main operation control relay group 27, an input device signal processing main board (hereinafter abbreviated as a main board) 29 as a control means, a DC converter 31 as a power supply unit, and a starter circuit cutoff means 33 shown in FIG. In preparation for the main components.
[0026]
The DC converter 31 changes a power supply voltage from a power supply battery (not shown) of the vehicle 1 to a predetermined voltage and supplies it to the main board 29. The main board 29 applies an operating voltage to the card holder 23 and the password input device 25 simultaneously when power is supplied. The above-mentioned ignition switch 17 is interposed in the drive power supply circuit between the DC converter 31 and the power supply battery. Therefore, the vehicle antitheft device 21 can be operated by operating the ignition switch 17 with the unique cylinder key 17a and supplying power to the main board 29.
[0027]
As shown in FIG. 1, the card holder 23 is electrically connected to the main board 29 via, for example, a password input device 25. A unique name card 23 a is inserted into the card holder 23. In the name card 23a, an ID code as a unique electronic code is written in a format such as magnetic information.
[0028]
The personal identification number input device 25 has a numeric keypad 25a, and number information corresponding to the depressed numeric keypad 25a is input. The input information input by the card holder 23 and the password input device 25 is output to the main board 29.
[0029]
The main operation control relay group 27 controls opening and closing of the power supply to the travel drive device and the vehicle mounted device or the control power supply to the hydraulic control solenoid. In this embodiment, the main operation control relay group 27 controls opening and closing of a first relay 35 that controls the engine cut solenoid 5, a second relay 37 that controls the starter motor 7, and a signal circuit from the unload lever 9. The third relay 39, the fourth relay 41 for controlling the traveling motor 3, the fifth relay 43 for controlling the solenoid of the traveling unload 11, and the sixth relay 45 for controlling the power supply circuit of the computer 13. .
[0030]
The first relay 35 to the sixth relay 45 may be ones that are closed at the time of operation or ones that are open at the time of operation, depending on the secondary side opening / closing control target. In addition, operation state detection signal lines 35a, 37a, 39a, 41a, 43a, 45a for detecting the state of the contacts during operation are led out to the first relay 35 to the sixth relay 45, respectively. All of these operation state detection signal lines 35a to 45a are connected to a starter circuit blocking means 33 described later.
[0031]
The main board 29 is supplied with power via the DC converter 31 when the ignition switch 17 is turned on. The main board 29 to which power is supplied receives the ID code of the name card 23a inserted into the card holder 23 and the password entered from the password input device 25, and specific information for verification is input in advance. The ID code and the unique information are collated and the personal identification number is collated, and when the result is matched, a drive permission signal is output to the plurality of main operation control relay groups 27 described above. .
[0032]
As shown in FIG. 3, the starter circuit interrupting means 33 includes an operation closing contact 47 and a contact controller 49. The closing contact 47 during operation is interposed in series between the starting circuit and the starter motor. Therefore, the above-described second relay 37 and this operation closing contact 47 are interposed in series between the starting circuit and the starter motor. The non-operating closing contact 47 shuts off the starter circuit and the starter motor when not in operation, and disables the starter motor from starting. The operating contact 47 is provided with a movable contact (not shown) and a coil portion 47a for driving the movable contact. For example, a relay can be used as the closing contact 47 during this operation. When the operation closing contact 47 receives a control signal from the contact control unit 49, the coil unit 47a is excited to operate, and the movable contact is moved to close the contact. Thereby, a starting circuit and a starter motor will be in a conduction state.
[0033]
The contact control unit 49 includes a plurality of logic elements 49a1, 49a2, 49a3, 49a4, 49a5, 49a6 corresponding to the first relay 35 to the sixth relay 45, and an output element 49b. The contact control unit 49 can be configured as one integrated circuit. In addition, this integrated circuit may be incorporated in the closing contact 47 during operation. That is, the starter circuit interrupting means 33 can be configured as a relay including the contact control unit 49.
[0034]
The logic elements 49a1 to 49a6 have two input terminals IN1 and IN2 and one output terminal OUT. Operation state detection signal lines 35a to 45a of the first relay 35 to the sixth relay 45 are connected to one input terminal IN1. Further, for example, a signal corresponding to the operation of the first relay 35 to the sixth relay 45 from the computer 13, that is, a high level (H) signal when opened or a low level (L) signal when closed is applied to the other input terminal IN 2. It is designed to be entered.
[0035]
The logic elements 49a1 to 49a6 send out individual output signals from the output terminal OUT when the input signals to the input terminal IN1 and the input terminal IN2 match. When individual output signals are sent from all of these logic elements 49a1 to 49a6, a general output signal is sent to the output element 49b. The output element 49b operates when a general output signal is input, and applies a current from the power supply battery to the coil portion 47a. That is, the contact controller 49 as a whole constitutes an AND circuit.
[0036]
Next, the operation of the vehicle antitheft device 21 configured as described above will be described.
FIG. 4 is a flowchart showing the operation procedure (1) of the vehicle antitheft device according to the present invention, and FIG. 5 is a flowchart showing the operation procedure (2) of the vehicle antitheft device according to the present invention.
[0037]
As shown in FIG. 4, in order to make the vehicle 1 travelable, first, the operator uses the unique cylinder key 17 a corresponding to the ignition switch 17 attached to the vehicle 1 to use the ignition switch 17. Is turned on (st1). As a result, as a first step, driving of the vehicle by a person who does not have the unique cylinder key 17a is prohibited and theft is prevented.
[0038]
Next, when the ignition switch 17 is normally turned on, power is supplied from the vehicle battery to the main board 29 via the DC converter 31 (st2). As a result, the card holder 23 waits for insertion of the name card 23a (st3).
[0039]
Next, when the name card 23a is inserted into the card holder 23 by the operator, the card holder 23 as an auxiliary input device is turned on (st4). This prevents theft by a person who does not have the name card 23a as the second stage.
[0040]
In the inserted name card 23a, the ID code written in the form of magnetic information or the like is read by the card holder 23, and the main board 29 reads the ID code as an electric signal through the card holder 23 (st5 ).
[0041]
The main board 29 takes out the “stored password” as the unique information stored in advance corresponding to the ID code read from the name card 23a (st6).
[0042]
Next, the operator inputs a unique “password” by the password input device 25 using the numeric keypad 25a (st7). This “password” is unique, for example, determined by the driver himself, and is stored in advance in the main board 29 in correspondence with the ID code of the name card 23 a possessed by the driver. The password stored in advance is “stored password”.
[0043]
If the “password” is input from the numeric keypad 25a, the main board 29 makes an inquiry with the “stored password” taken out corresponding to the ID code of the name card 23a (st8). If these “password” and “stored password” match, it is determined that the name card 23a and the driver are authentic, and a drive permission signal is output to the main operation control relay group 27 (st9). . Thus, as a third step, driving of the vehicle by a person who does not know the “password” is prohibited, and theft is prevented even if the name card 23a is carried and used.
[0044]
If the input “password” does not match the “stored password”, the process returns to the “password” input procedure st7. For example, the count is performed so that the number of re-inputs of the “password” is limited to about 3 times, and when the number is further input, the input of the “password” is rejected. Therefore, in this case, the vehicle 1 cannot be driven at this time.
[0045]
The main operation control relay group 27 to which the drive permission signal is input closes the drive circuits of the travel drive device, the travel assist device, and the vehicle mounted device. As a result, the on-vehicle equipment other than the starter motor 7 including the travel drive equipment can be driven.
[0046]
Next, when all of the first relay 35 to the sixth relay 45 of the main operation control relay group 27 are operated, the operation state is detected from the operation state detection signal lines 35a to 45a to the logic elements 49a1 to 49a6 as shown in FIG. A signal is input (st10). When the operation state detection signal input to the input terminal IN1 matches the input signal input to the input terminal IN2, the logic elements 49a1 to 49a6 output individual output signals from the output terminal OUT (st11).
[0047]
The contact controller 49 determines whether or not individual output signals are output from all these logic elements 49a1 to 49a6 (st12), and outputs all output signals to the output element 49b when all the individual output signals are output. (St13).
The output element 49b operates when the overall output signal is input, applies current from the power supply battery to the coil unit 47a, and operates the closing contact 47 during operation (st14).
[0048]
As a result, both the second relay 37 and the contact point of the closed circuit contact 47 during operation are closed, the starting circuit and the starter motor are brought into conduction, and the starter motor 7 can be started. As a result, as a fourth stage, starting of the vehicle 1 is prohibited when all of the first relay 35 to the sixth relay 45 do not operate.
[0049]
Thus, according to the vehicle antitheft device 21 described above, the first relay 35 to the sixth relay 45 are interposed in the drive power supply circuit of the travel drive device and other vehicle-mounted devices, and the drive power supply is shut off. Since it was made possible, the drive control object can be extended not only to the travel drive device but also to other vehicle-mounted devices. Therefore, even if only the engine is illegally driven, other vehicle-equipped devices are not supplied with driving power, which causes trouble in traveling and makes traveling impossible.
[0050]
In other words, in the conventional vehicle antitheft device, the engine is the only object to be controlled, and therefore the engine can be driven if the ignition switch and the fuel supply means are improperly connected. It becomes operable and does not interfere with running. On the other hand, in the vehicle antitheft device 21 according to the present invention, other vehicle-mounted devices cannot be operated unless all of the main operation control relay groups 27 are illegally connected, which involves extremely complicated work. In effect, it becomes impossible to drive the engine by incorrect connection. As a result, even if only the engine becomes drivable, other vehicle-mounted devices remain inoperable, and thus travel is restricted. For example, for vehicles in which blades and backhoes are used as vehicle-mounted devices. In this case, since the blades and the backhoe are in contact with the ground, the vehicle 1 can be reliably prevented from being stolen.
[0051]
Further, in addition to the second relay 37 described above, an operation closing contact 47 of the starter circuit breaking means 33 is connected in series between the starting circuit and the starter motor 7, and the first relay 35 to the sixth relay 45. Since the closing contact 47 at the time of operation is closed only when all of the above have operated, if any one of the first relay 35 to the sixth relay 45 is not operating, the starter motor 7 cannot be started. can do. As a result, compared to the case where the starting circuit and the starter motor 7 are interrupted only by the second relay 37, it is possible to make it difficult to start the vehicle by unauthorized connection, and to more reliably prevent the vehicle 1 from being stolen. Can do.
[0052]
By the way, the starter circuit shielding means 33 in the above embodiment is not limited to the circuit configuration shown in FIG. That is, the starter circuit shielding means 33 is configured to operate so as to conduct between the starter circuit and the starter motor 7 only when all of the plurality of relays that control opening / closing of the power supply to the travel drive device and the vehicle mounted device are operated. If it is.
[0053]
In the above embodiment, the case where the card holder 23 is used as an auxiliary input device has been described as an example. However, as shown in FIG. 6, the auxiliary input device is an electromagnetic induction non-contact card (ID card). 51 or a remote control key 53 of radio wave type or infrared type.
[0054]
When these auxiliary input devices are used, an auxiliary input device signal processing board 55 for receiving a code signal from the ID card 51 or the remote control key 53 is connected to the main board 29.
[0055]
When such an ID card 51 is used, it is possible to prevent deterioration of the ID code reading performance due to wear as compared with the case where the contact type name card 23a is used.
[0056]
Further, if the remote control key 53 is used, it is possible to prevent the deterioration of the ID code reading performance as in the case of the ID card 51, and the code signal transmission distance is increased as compared with the non-contact type ID card 51. It is also possible to send a code signal from a remote location, and for example, the ID code can be sent while being worn on the body, and convenience can be improved.
[0057]
Further, in the above-described embodiment, the “stored password” as the unique information for verification is extracted from the ID code of the name card 23 a serving as the auxiliary input unit, and the “stored password” and the key input unit 25 “ In the above description, the ID code, the password number, and the stored password number stored in advance are compared and determined at the same time. The control means for outputting a drive permission signal to a plurality of relays, such as a configuration having a plurality of relays corresponding to a code and a code number, is input from each of an auxiliary input means and a key input means. The configuration is not limited as long as information is obtained.
[0058]
Furthermore, in the above-described embodiment, the vehicle-mounted devices that are driven and controlled by the main operation control relay group 27 are the engine cut solenoid 5, the starter motor 7, the unload lever 9, the travel motor 3, the travel unload 11, and the computer 13. Although described as an example, vehicle-mounted equipment that is driven and controlled by the main operation control relay group 27 regulates traveling even if it is other work equipment such as blades and backhoes, and has the same effect. It is.
[0059]
【The invention's effect】
As described in detail above, the vehicle antitheft device according to the present invention includes a switching power supply circuit for driving drive devices and other vehicle-mounted devices, and an electronic code for auxiliary input means. Since the drive power is supplied to all on-vehicle equipment only when the collation result with the specific information for collation that is set in advance is determined as the input information using the PIN number by the key input means, the engine Even if only the power is illegally driven, if the matching result between the electronic code and the personal identification number is not determined to match the preset unique information, the drive power to other on-vehicle equipment is It can be shut off to disable running.
[0060]
That is, in this vehicle antitheft device, not only the ignition switch but also the auxiliary input means and the key input means are provided, so that multiple antithefts can be prevented. If the vehicle is not properly operated, it becomes impossible to handle the vehicle, and if all the switching devices are illegally connected, it is extremely complicated. In addition, it is impossible to drive each device due to unauthorized connection, and even if only the engine is in a driveable state, other on-vehicle devices remain in an inoperable state, and travel is restricted. Thus, theft of the vehicle is surely prevented.
[0061]
In addition, since the closing contact for operation of the starter circuit shut-off means is connected in series between the starter circuit and the starter motor, the closing contact for operation is closed only when all of the switching means are operated. If any one of the means is not operating, the starter motor can be disabled. As a result, the starter motor and the starter motor are cut off from each other in a double manner, and it is possible to make it difficult to start the vehicle by unauthorized connection, and the vehicle can be more reliably prevented from being stolen.
[0062]
Further, in the configuration in which the auxiliary input means is a name card holder, a unique name card is inserted so that, for example, a unique electronic code written in the name card in the form of magnetic information or the like is transferred to the name card holder. It is possible to read the control means via the control means, that is, it is possible to specify the driver of the vehicle.
[0063]
Further, in the configuration in which the auxiliary input means is a contactless card, a unique electronic code written in the contactless card is read into the control means in a contactless manner, and thus the contact type name card is used. Compared to the case, deterioration of the code reading performance due to wear is prevented.
[0064]
In addition, in the configuration where the auxiliary input means is a radio wave type or infrared type remote control key, a unique electronic code is transmitted by the radio type or infrared ray by this remote control key, and is read into the control means without contact, Accordingly, as in the case of the contact type name card, deterioration of the code reading performance due to wear is prevented, and the code signal transmittable distance is increased.
