Abstract

FIELD: transportation.

SUBSTANCE: invention relates to protection of vehicles (transport facilities) from unauthorised use and is intended for prevention of theft of transport facilities. The procedure is as follows. The first step is authorising the transport facility protection condition. Then the first unit and one of the portable tracking appliances get cut in to identify a user outside the vehicle. Given the positive condition, the protection is cut off and the User is allowed an access into the vehicle. After cutting in the ignition, the first unit of reading out the data and the transponder (a marking), the User inside the vehicle is identified and in case of a negative result the engine is blocked. If the user lost its trinket or a transponder or if they were stolen, or if the first readout unit fails but the user needs its car, the car door is opened and the activated protection circuit is cut out to prevent operation of the sound and light alarm signals. Also, blocked is the operation of the antitheft system aimed at locking the engine operation. For this, inside the vehicle one more readout unit is installed and the User is provided with an extra transponder. To stop the alarm signalling activated by the User, an emergency transponder is carried into the zone of action of the second data readout unit. The emergency transponder code is identified to cut off signaling whatsoever and the engine is unlocked.

EFFECT: invention allows simplifying the procedure of removing the protection without decrease in safety.

Description

The invention relates to techniques for electronic protection of vehicles (TC) from unauthorized use and is intended to prevent theft (theft) of the vehicle.

Known anti-theft device for vehicles according to patent RU No. 2090395, B60R 25/00, containing a central control unit and sensors of unauthorized impact on the vehicle, as well as nodes of sound and / or light alarm and nodes for blocking doors and functional bodies of the vehicle connected to the onboard power supply, respectively, before and after the ignition switch is inserted into it.

The specified anti-theft device for the vehicle also includes an identification unit, made in accordance with patent RU No. 2099904, H04Q 7/00. The identification unit includes a wearable part - an electronic key (tag or keyfob) and a transportable part - a reading unit connected to the start-up input of the central control unit, the signal input of which is connected to the outputs of sensors and blocking units, the first output is connected to the control inputs of sensors, nodes alarm and door blocking units, and the second output with control inputs of the blocking units of the vehicle functional bodies, while the input and first output of the central control unit, control inputs and outputs sensors, the control inputs of the alarm nodes, the control inputs and outputs of the blocking nodes are combined with their power inputs, and the second output of the central control node with its feedback input connected to the on-board power supply after the ignition switch, while the alarm nodes are configured to reception from the on-board power supply network, and sensors, blocking units and a central control unit - with the possibility of forming, transmitting to the on-board power supply network and receiving code from persecuted.

The disadvantage of the above anti-theft device for the vehicle is the inability to program the operating modes of the security and anti-theft nodes of the vehicle.

This drawback is eliminated in the BLACK BUG SUPER VT-8 5, BT-85W, BT-85L security and anti-theft systems commercially available by the applicant enterprise (Automotive Security Systems catalog, Altonika LLC, issue 9, 2006, p.4- 6), in which the method of protecting the vehicle from unauthorized use according to patent RU No. 2179122, 60R 25/00 is implemented. According to this method, the security part of these security and anti-theft systems is controlled by a key fob and / or transponder, and their anti-theft part is controlled by a transponder, and when trying to unauthorized access to the vehicle using the security part of the complex, light and / or sound alarms are activated, and using the anti-theft alarm parts of the complex block the operation of the engine and enter the anti-theft alarm system in a panic mode with the connection of additional, previously not shown, means of alarm. Remote recognition of transponder codes and remote controls is carried out by the information reading unit installed on the vehicle.

Each of the transponders has a unique code. The information reading unit remotely determines the presence or absence of a transponder in its coverage area and reacts accordingly. So, when identifying a transponder, the security and anti-theft complex allows you to freely use the vehicle. The range of the transponder is such that you can control the security and anti-theft complex without removing the transponder from your pocket. In the event that the vehicle user is not identified, the anti-theft alarm system keeps the vehicle engine in a locked state.

The memory of the security and anti-theft complex can be written codes of three different transponders. It is possible to delete codes of lost transponders. The recording of new transponders in the memory of the anti-theft alarm system is carried out using the so-called Master-tag, the information in which is entered using a special programmer. The transponder can be made, for example, in the form of a plastic card, which does not require a power source.

With the help of remote controls, the vehicle is armed, disarmed, mode control (silence alarm, search, panic), as well as control of programmable channels. In relation to the transponder, the key fob is an additional control element.

In critical situations (in cases of loss, malfunction or theft of transponders and remote controls), the security part of the complex can work without them - using a personal secret code. In case of unauthorized opening of the hood, trunk, interior doors or when the brake pedal is pressed, accompanied by the corresponding sensor responses, the anti-theft part of the complex goes into alarm mode and keeps the engine in a locked state.

The vehicle protection method described above is the closest analogue of the proposed technical solution.

Its fundamental drawback is as follows.

In case of a malfunction of the recognition unit for some reason (for example, in case of failure of the information reading unit or in case of a radio contact with the transponder due to strong external interference radiation), an emergency occurs when the user cannot use his vehicle and is forced to call a tow truck.

In order to avoid such a situation, the so-called service mode (VALET mode) is provided in the aforementioned security and anti-theft complex - that is, the procedure for disarming and unlocking the engine. The security and anti-theft complex can be switched to VALET mode by the following methods ("Security and anti-theft complex BLACK BUG SUPER BT-85W", User Manual, LLC Altonika, p.23, 24):

1. If the arming of the vehicle was carried out using a transponder, then using one of the transponders of the security and anti-theft complex, you can automatically turn off the security mode. To do this, the user must approach the vehicle by the transponder identification distance. The security mode will be automatically disabled, and the user will be notified about this by two sound and light signals. After disabling the security mode, the actions specified during the programming of the security and anti-theft parts of the security and anti-theft complex will be performed: door locks are open, interior lighting is turned on, windows and other possible similar actions are lowered.

2. If the user has a keyfob, he can disable the security mode by pressing one of the keyfob buttons. After disabling the security mode when there is no transponder in the recognition zone and when the conditions for automatic arming of the vehicle are fulfilled, after a period of time set during programming, the security mode will be automatically activated.

3. The security mode can be disabled without the use of a transponder and a key fob - by entering a special code (PIN-code). To do this, the user, opening the driver’s door, automatically enters the anti-theft alarm system in alarm mode. After that, the user takes his place in the vehicle interior, turns on the ignition, presses the VALET button (located on a special indicator) and holds it until a sound signal appears. Further, the user releases the VALET button and no later than twelve seconds later starts entering the PIN code by briefly pressing the VALET button the number of times corresponding to the number being dialed. In this case, the numbers from 1 to 9 and then 0 will light up sequentially on the indicator. The indicated numbers are fixed by pressing / releasing the brake pedal. In this case, the digit on the indicator screen goes out and a special sound signal confirms the entry of this digit. After entering all the digits of the PIN code correctly, the alarm mode is turned off and the vehicle is disarmed, as indicated by the appearance of a dot on the indicator screen. If the engine was blocked, then the engine is unlocked at the same time, that is, the vehicle is allowed to move.

On the one hand, the procedures for disabling the security mode described above allow avoiding situations in which the user would be forced to call a tow truck, but, on the other hand, they reduce the degree of protection of the vehicle. For example, having selected a key fob and having instructions on how to use it, an attacker can disarm the vehicle at the touch of a button and penetrate the vehicle without hindrance. It is likely that the attacker may also know the PIN code. Then the attacker will be able to use it to disarm the vehicle.

The present invention addresses these drawbacks. The purpose of the proposed technical solution is to simplify the procedure for transferring a security and anti-theft system into VALET mode without reducing the degree of protection of the vehicle from intruders.

The subject of the invention is a method of protecting a vehicle from unauthorized use, in which the vehicle is protected, using the first information reading unit and one of the key fobs, a user who is outside the vehicle is identified, if the procedure is positive, the security mode is disabled and the user is allowed access to the vehicle, and after turning on the ignition using the first information reading unit and the transponder (tag), the user identification procedure is carried out inside the sal it is a vehicle, and in case of a negative result of this procedure block the operation of the engine of the vehicle, in the case of loss (theft) of the key fob and transponder or the inoperability of the first information reading unit, if the user needs to use the vehicle, the driver’s door is opened and the alarm mode activated by opening the driver’s door the security part of the complex with sound and / or light alarms and radio alerts, and with the anti-theft part of the complex and by blocking the operation of the engine, in this case, the second information reading unit is covertly installed in the vehicle cabin, the vehicle user is equipped with an emergency transponder, and to stop the alarm mode activated by opening the driver’s door, the specified emergency transponder is brought into the coverage area of the second information reading unit, the emergency transponder code is recognized, after which stops the supply of sound and / or light signals and radio alerts and unlocks the engine.

Particular features of the invention are as follows.

The emergency transponder is stored in a hidden place on the vehicle.

A blocking command is sent to the vehicle over the air, by which the operation of the engine of the vehicle is blocked and recognition is prohibited by the first information reading unit, while the blocking command is canceled either by identifying the emergency transponder code or by sending the blocking cancellation command over the vehicle over the air.

A blocking command is sent to the vehicle over the air, by which the operation of the engine of the vehicle is blocked and recognition by means of the first and second information reading blocks is prohibited, and the blocking command is canceled by issuing the blocking cancellation instruction over the vehicle over the air.

The objective of the present invention is to provide a technology for protecting the vehicle against unauthorized use, which would simplify the process of disarming the vehicle without reducing the degree of protection of the vehicle against intruders.

The technical result provided consists in using the procedure for forcibly transferring the vehicle to alarm mode by opening the door and the procedure for additional identification of a special code used to disarm the vehicle. The specified code is recorded in the emergency transponder, located at the user of the vehicle, or stored in a secret place of the vehicle.

The essence of the invention is illustrated in the drawing, which shows a structural diagram of a security and anti-theft complex that implements the claimed method of protecting the vehicle from unauthorized use.

In the specified drawing, the following notation is used:

1 - transponder; 2 - remote control; 3 - the first block of reading information; 4 - control unit of the security part of the complex; 5 - control unit anti-theft part of the complex; 6 - security part of the complex; 7 - anti-theft part of the complex; 8 - transportable transceiver; 9 - wearable transceiver; 10 - Master tag; 11 - the second block of reading information; 12 - emergency transponder.

The first block 3 of information reading is connected by radio with the transponders 1 and the Master-tag 10 located at the users’s site. Using them, users can control the security 6 and anti-theft 7 parts of the complex while inside the vehicle.

In addition, when arming and disarming the vehicle, each user uses his keyfob 2, configured to transmit various commands over the air to the first information reading unit 3. In this case, the user can be at a sufficiently large (up to 250 m) distance from the vehicle. In the security and anti-theft complex, which is the closest analogue of the security and anti-theft complex under consideration, up to three transponders (tags) 1 and up to three remote controls can be used.

The output of the first information reading unit 3 is connected to the first inputs of the control unit 4 of the security part of the complex and the control unit 5 of the anti-theft part of the complex. The first output of the control unit 4 of the security part of the complex is connected to the second input of the control unit 5 of the anti-theft part of the complex and to the input of the security part 6 of the complex, the output of which is connected to the second input of the control unit 4 of the security part of the complex. The control unit 4 of the security part of the complex is connected, in addition, with a radio broadcasting channel consisting of transportable 8 transceivers connected with each other via radio. The output of the anti-theft part control unit 5 of the complex is connected to the input of the anti-theft part 7 of the complex and to the third input of the control unit 4 of the security part of the complex.

An emergency radio channel has been introduced into the security and anti-theft complex. It is formed by a second information reading unit 11, the output of which is connected to an additional input of the anti-theft part of the complex control unit 5, and an emergency transponder 12, configured to interact over the air with the second information reading unit 11, if the emergency transponder 12 is close enough (no more meter) the distance from the second block 11 of reading information.

All the blocks and units of the security and anti-theft complex shown in the drawing are also used in the closest analogue - in the security and anti-theft complex "BLACK BUG SUPER" BT-85 (Complex "BLACK BUG SUPER" BT-85. User manual, LLC Altonika, 2002, www.altonika.ru).

The differences are only in the presence of the second information reading unit 11 and the emergency transponder 12, structurally made in the same way as, respectively, the first information reading unit 3 and the transponder 1, as well as in the presence of an additional input to the anti-theft part control unit 5.

These changes cause differences in the order of actions and in the conditions of their implementation, which relates to the features of the method. Therefore, the possibility of practical implementation of the scheme shown in the drawing, which implements the claimed method, is not in doubt.

Security and anti-theft complex that implements the considered method of protecting the vehicle from unauthorized use, works as follows.

The principle of operation of the security and anti-theft complex is based on remote identification of the "electronic key" code. The recognition principle used is radio frequency. As an "electronic key" transponders 1 are used - devices made in the form of a plastic card without buttons, or devices with push-button control - remote controls 2. These devices are available to users of the vehicle. In this case, for identification with the help of transponder 1, the user only needs to occupy such a place in the vehicle compartment at which transponder 1 falls into the coverage area of the first information reading unit 3. Unlike the keyfob 2, transponder 1 does not require a power source. In the security and anti-theft complex, several transponders 1 and remote controls 2 can be used. Code information is recorded in them using a programmer (not shown in the drawing).

For greater clarity, the controls of the security and anti-theft complex are divided into control unit 4 of the security part of the complex and control unit 5 of the anti-theft part of the complex, with which the user controls, respectively, the security 6 and anti-theft 7 parts of the complex.

The security part 6 of the complex includes sensors of unauthorized influence (for example, motion or shock sensors) and alarm blocks (sound and / or light).

A high level of vehicle protection against theft is achieved by the use of a set of remotely controlled relays in the anti-theft part 7 of the complex, which are installed anywhere in the vehicle without laying additional wires.

Remote-controlled relays are controlled by special coded signals via standard vehicle power wiring.

The transportable transceiver 8, connected over the air with a portable transceiver 9, performs both a security and anti-theft function. So when a sensor is triggered in the security part 6 of the complex, an alarm signal comes from the security part 6 of the complex to the control unit 4 of the security part of the complex. Upon an alarm, the control unit 4 of the security part of the complex generates a command that is sent to the transportable transceiver 8, emitting a signal corresponding to the received command. This signal is received by the wearable transceiver 9 and serves the user (or special operator) as an alert that an unauthorized impact on the guarded vehicle has occurred. Using the reverse radio channel "wearable transceiver 9 → transportable transceiver 8 → security unit 4 control unit", the user can remotely block the engine and thereby prevent unauthorized movement of the vehicle.

The radio channel for notifying the user (or operator) and transmitting the vehicle blocking signals can be performed, for example, in the form of a paging, cellular or trunking channel. The choice of type of radio channel for this invention is not significant.

Blocking is carried out as follows. The blocking command sent over the air by the wearable transceiver 9 arrives at the transportable transceiver 8. The transportable transceiver 8 analyzes the received command, identifies it with a specific blocking command and transmits a special signal to the control unit 4 of the security complex. In the control unit 4 of the security part of the complex, a forced blocking command is generated by the received signal, which enters the security part 6 of the complex and in the control unit 5 of the anti-theft part of the complex. Security part 6 of the complex, on this command, generates special light and / or sound signals warning that in the near future the vehicle engine will be forcibly blocked. The control unit 5 of the anti-theft part of the complex, after several (no more than ten) seconds after the receipt of a forced blocking command, prohibits the receipt of signals from the first information reading unit 3 and generates a command to block the vehicle engine. This command enters the anti-theft part 7 of the complex. After the receipt of this command, the anti-theft part 7 of the complex blocks the vehicle engine. This lock can only be removed with the help of another command formed by the wearable transceiver 9. Using the transponders 1, remote controls 2 or Master tags 10, it is impossible to unlock the vehicle engine. This mode is designed for the case when hijackers capture the vehicle, take possession of the transponder 1 and / or the keyfob 2 of the user, after which the user is thrown out of the vehicle.

In the memory of the first information reading unit 3, codes of several transponders 1 and key fobs 2 can be recorded. It is possible to delete codes of lost (stolen) transponders 1 and key fobs 2. Recording of codes of "new" transponders 1 and key fobs 2 is carried out using Master Tag 10, multi-page memory which stores all the information about the settings of the security and anti-theft complex. To make changes to the algorithm of the security and anti-theft complex using the special software and programmer, the contents of the Master tag 10 are changed, and then the contents of the Master tag 10 are copied to the memory of the first information reading unit 3.

In special cases, disarming the vehicle is implemented due to the introduction of a second information reading unit 11 and emergency transponder 12 into the security and anti-theft complex.

Interacting with each other over the air, they form an emergency radio channel, acting on the same principles as the radio channel "first block 3 for reading information - transponder 1". The difference lies only in the special code recorded in the memory of the second block 11 for reading information using the Master tag 10, specially brought to the second block 11 for reading information for this operation. In emergency transponder 12, the specified special code is recorded using the programmer.

The disarming mode is implemented as follows.

The user, having discovered that the anti-theft alarm system does not respond to the key fob 2 (for example, due to a malfunction of the first information reading unit 3) or that both the transponder 1 and the key fob 2 have been stolen from it, opens the driver’s door and enters the vehicle interior. In this case, the limit switch of the driver’s door is activated, which is part of the security part 6 of the complex, and the alarm starts to work. Further, the user detects that he does not have transponder 1 or is convinced that the anti-theft alarm system does not respond to his transponder 1 (for example, due to a malfunction of the first information reading unit 3). Knowing the location of the second block 11 for reading information, the user brings to it an emergency transponder 12, taken by him, for example, from a secret place known to him in the vehicle. After that, the second information reading unit 11 reads from the emergency transponder 12 a special code designed to put the anti-theft alarm system into VALET mode. This special code in the second information reading unit 11 is compared with a special code previously recorded in its memory. If these special codes coincide, the second information reading unit 11 includes an anti-theft part control unit 5, which sends an unlock command to the anti-theft part 7 of the complex. This command is sent to the authorities providing engine blocking in the guard mode (immobilizer and / or controlled relays). As a result of the operation of these organs, the engine is unlocked, and the vehicle can begin to move. At the same time, the unlock command is sent to the third input of the control unit 4 of the security part of the complex. According to this command, the control unit 4 of the security part of the complex generates a command to turn off the sound and / or light alarm signal that is sent to the security part 6 of the complex, as well as the command to turn off the alarm broadcasting sent to the transportable transceiver 8. For these commands, the security part 6 of the complex interrupts the sound and / or light signals, and the transportable transceiver 8 interrupts the supply of alarm signals.

Above, it was considered blocking the engine of the vehicle by a command received by radio on the transportable transceiver 8, and it was indicated that the transportable transceiver 8 identifies the received command with a specific blocking command. Now, after considering the operation of the second information reading unit 11 and the emergency transponder 12, it is necessary to clarify the concept of a “specific blocking command”. There are two different locking commands:

- according to the main blocking command, the engine is blocked and the entry to the control unit 5 of the anti-theft part of the signal complex from the first information reading unit 3 is blocked. This command does not prohibit the receipt to the control unit 5 of the anti-theft part of the signal complex from the second information reading unit 11;

- by an additional blocking command, the engine is blocked and the entry to the control unit 5 of the anti-theft part of the signal complex is blocked both from the first 3 and from the second 11 information reading blocks.

It should be noted that one has to resort to the issuing of a blocking command in critical cases when an attack by an attacker took place on a disarmed vehicle, as a result of which the transponder 1 and key fob 2 were taken from the user, and the user was deleted by the attacker from the vehicle. In this case, the user submits one of the blocking commands (for example, by contacting the operator of a cellular mobile communication network).

The main blocking command does not prohibit the arrival of signals to the control unit 5 of the anti-theft part of the complex from the second information reading unit 11. Therefore, after the attackers make sure that the vehicle’s engine is locked and using the transponder 1 and remote control 2 taken from the user it is not possible to unlock it, they will be forced to leave the captured vehicle. The user, having found his vehicle, can open his door, remove the emergency transponder 12 from a secret place in the vehicle and use the second 11 information reading unit to switch the vehicle to VALET mode, while unlocking the vehicle engine.

An additional blocking command prevents the user from unlocking the vehicle engine.

However, with any blocking command, the user still has the opportunity to unlock the vehicle engine by issuing the command to cancel the blocking. This command is received by the portable transceiver 8, enters from it into the control unit 4 of the security part of the complex and is transmitted further to the security part 6 of the complex and to the control unit 5 of the anti-theft part of the complex. The control unit 5 of the anti-theft part of the complex unlocks the engine of the vehicle and allows the reception of signals from the first 3 and second 11 information reading units, the security part 6 of the complex gives special light and / or sound signals.

Thus, the features of the security and anti-theft complex that implements the inventive method are fully considered.

The combination of the above essential features allows us to solve the problem - to create such a technology for protecting the vehicle against unauthorized use that would simplify the procedure for removing the vehicle from protection (transferring the security and anti-theft system to VALET mode) without increasing the risk of intruders entering the vehicle.

The provided technical result consists in using the procedure for the forced transfer of the security and anti-theft complex of the vehicle to alarm mode by opening the door of the driver of the vehicle and the procedure for additional identification of the special code used to put the security and anti-theft complex into VALET mode. The specified special code is recorded in the second block 11 for reading information and in the emergency transponder 12, located at the user of the vehicle or stored in a secret place of the vehicle.
