Description

FIELD OF THE INVENTION

This invention relates to the field of protection of vehicles against theft.

State of the art

Currently, automobile anti-theft systems are widely used, in which the determination of the fact of theft is based on the owner identification system. This can be, for example, identifier tags, remote controls, hidden buttons, etc. In such systems, in the absence of identification, the start and operation of the engine are blocked. A significant drawback of such systems is the inability to distinguish between the fact of real hijacking from the erroneous identification of the owner or its impossibility due to a malfunction of the identification unit (for example: battery of a remote keyfob). In these systems, all blocked car circuits remain broken from the moment of arming to a successful authorization. This allows the hijacker to find locked circuits using diagnostic equipment.

In US patent No. 5061915 (publ. 29.10.1991) describes a device whose distinctive feature is the correct sequence of actions of the owner of the car to disarm the anti-theft system. In Japanese laid-out application No. 2000-038113 (publ. 08.02.2000), in Russian patents No. 2185297 (publ. 20.07.2002), 2198801 (publ. 02.20.2003), 2179122 (publ. 10.02.2001), 2124992 ( publ. 01/20/1999) devices are described that are distinguished by methods for disarming systems by owners, features of interaction between control units and executive relays, parameters of executive relays (wired, wireless), types of data transmission channels from control units to executive devices, types of channels communication between owner authorization devices and control units s by means of protection from destruction blocking relay thief, etc.

The closest analogue is the anti-theft device described in the patent of the Russian Federation No. 2160196 (publ. 10.12.2000). It includes a processor unit and several locking device 3 lock. The system includes a motion sensor. When trying to steal, the system allows you to start the engine, but blocks it after the start of movement. The disadvantage of this device is that in any case, it allows you to start the engine. If the start was made not by the hijacker, but by the owner without disarming the system, all relays will be blocked after the start of movement. That is, the system does not distinguish between the fact of theft and erroneous operation. The engine can lock on the go, even if the owner is driving, which may cause a dangerous situation for the owner. In addition, in this case, it is impossible to block the vehicle circuits, the break of which causes damage to the car. Since on-board computer registers everything, even short-term malfunctions (“errors”) in modern cars, a situation may occur when, due to such a malfunction, the vehicle will not be allowed to start until information about it is deleted from the computer’s memory.

DETAILED DESCRIPTION OF THE INVENTION

The claimed method can be implemented in the anti-theft system of the vehicle, the General block diagram of which is presented in figure 1. The vehicle may be, for example, a car, boat, helicopter, etc., i.e. any self-propelled vehicle with any engine in which the ignition system is used. The anti-theft system of a car is described below as an example, however, it should be understood that this example is purely illustrative and does not limit the claimed invention, the scope of which is determined only by the claims, taking into account equivalents.

The anti-theft system of figure 1 contains a control unit 1 connected by a communication channel 2 with devices 3 for blocking a functional organ. Each of the functional organ blocking devices 3 is connected to its functional organ 4. In FIG. 1, this is displayed by the same indices i at the reference positions of the locking devices 3 and the functional organs 4, where i = 1, 2, ..., N, a N is equal to the number functional bodies 4 of the vehicle on which the device 3 blocking the functional body. 1, the control unit 1 also shows the ignition input 5, the control input 6 and the authorization input 7, the purpose of which is explained below.

As functional bodies 4, any of the following group of devices can be used: ignition circuit, starter, fuel pump, engine control unit. In principle, this group may include any other devices involved in the operation of the vehicle.

The implementation of the control unit 1 is illustrated in figure 2. The control unit 1 is connected to the on-board power supply network 8 of the vehicle and contains a node 11 for determining the fact of engine operation, a node 12 for transmitting commands, a node 13 for determining the fact of movement, and a node 14 for analyzing information and synthesizing commands. In addition, the control unit 1 may include an identifying data verification unit 15, specially shown in FIG. 2 by a dashed line to emphasize the optionality of its presence in the control unit 1.

The node 11 determining the fact of engine operation, the node 13 determining the fact of movement and the node 15 for verifying identifying data (if it is present in the control unit 1) are connected by a bus to the node 14 for information analysis and command synthesis, the output of which is connected to the node 12 for transmitting commands. Figure 2 shows the output of the command transmission unit 12, connected to the communication channel 2 (figure 1). In addition, figure 2 in the control unit 1 specifically shows the connection of the node 11 determining the fact of the engine to the on-board power supply network 8 of the vehicle.

The site 11 determine the fact of the engine is made with the possibility of determining the fact of the engine, for example, by the presence of voltage ripples in the on-board power supply of the vehicle. Such voltage ripples are caused by the operation of an electric generator in a vehicle. The node 11 determining the fact of engine operation may contain, for example, a band-pass filter at frequencies from 150 Hz to 10 kHz, the output of which is connected to the comparator. Such a circuit makes it possible to measure the frequency of pulses at the output of the comparator that appear as a result of the operation of the electric generator and arrive at the information analysis and command synthesis unit 14, which in turn makes it possible to determine the state of the engine “wound up” or “not wound up”, as well as the moment of transition state to another.

The command transmission unit 12 is configured to transmit the commands generated by the information analysis and command synthesis unit 13 to the functional organ blocking devices 3. These commands are transmitted in encoded form on the communication channel 2. As the communication channel 2, you can use any known communication channel, the type of which determines the device and the principle of operation of the command transmission unit 12.

In a preferred embodiment of the illustrated anti-theft system, a vehicle power supply network 8 is used as the communication channel 2. The advantages of this communication channel are stealth and noise immunity, because interception of commands is impossible without penetration into the vehicle (car in this example) and there are no conflicts with the radio-channel devices of the car. However, the vehicle’s on-board power supply network 8 has an extremely low AC resistance, which makes it difficult to create a signal of sufficient amplitude in it to be perceived by the device 3 to block the functional organ.

Therefore, the command transmission unit 12 in the anti-theft system under consideration contains a push-pull key stage, the output of which is connected through a isolation capacitor to one of the terminals of the primary winding of a step-down pulse transformer, the second terminal of which is connected to a common wire. The secondary winding of the step-down pulse transformer with one output through another isolation capacitor is connected to the positive wire in the vehicle's on-board power supply network 8, and its second output is directly connected to the common wire. This capacitor and the secondary winding of the transformer are an oscillatory circuit with a resonant frequency almost equal to the frequency of the carrier oscillation. Such a circuitry solution allows you to create a large amplitude signal with high efficiency in the on-board power supply network 8.

Node 13 determining the fact of movement is made with the possibility of determining the fact of movement of the vehicle, regardless of the reason for such movement. To this end, the displacement fact determination unit 13 may comprise, for example, a displacement sensor configured to generate random frequency pulses in the presence of vehicle vibration, and a medium frequency meter configured to measure the average pulse repetition rate from the displacement sensor.

The displacement sensor can be implemented on the basis of a metal ball freely lying on the contacts in a certain limited volume. When the car (or other vehicle) vibrates due to its movement (for any of the possible reasons: moving on its own, towing, moving on a tow truck, etc.), the ball starts moving and randomly closes and opens contacts. The frequency and duration of the pulses generated in this case will be random functions of time due to the fact that the vibration of a car (or other vehicle) is random. The pulses formed in this case pass through a differentiable RC chain, which forms a fixed charge for each pulse from the displacement sensor, determined by its time constant. This charge is supplied through a transistor switch to an integrating RC circuit with a sufficiently large time constant, so that the voltage on this integrating RC circuit is proportional to the average pulse frequency from the displacement sensor. The generated voltage is measured by the node 14 information analysis and synthesis of commands.

The information analysis and command synthesis unit 14 is configured to analyze the information received from the engine operation fact determination unit 11 and the movement fact determination unit 13, as well as a signal of a positive result of checking the identification data of the driver and (or) the authorized vehicle user (described later) , and with the possibility of synthesizing the corresponding commands and issuing them to the node 12 transmitting commands. As the node 14 for information analysis and command synthesis, you can use the microcontroller (microprocessor with memory), programmed to run the program, determined by the following algorithm of the anti-theft system of the present invention. The output signal of the node 14 information analysis and synthesis of commands can be a rectangular signal of broadband frequency manipulation, which ensures high noise immunity.

The aforementioned signal about a positive result of verification of the identification data of the driver and / or authorized user of the vehicle can be sent to the information analysis and command synthesis unit 14 from input 7 of the control unit 1 if an external authorization device is used. Otherwise, the vehicle’s anti-theft system may include an identifying data verification unit 15, for example, a radio receiver for receiving signals from remote controls, RFID tags and other well-known means of authorizing a driver or an authorized user of a vehicle. When this input 7 authorization becomes unnecessary.

The control input 6 shown in FIGS. 1 and 2 serves to supply to the control unit 1 a signal containing information about opening the doors of the vehicle. Such a signal can come from any well-known sensor used in a vehicle, for example, from a simple contact sensor, which is triggered when the contacts open due to opening the door.

The ignition input 5 shown in FIGS. 1 and 2 serves to supply to the control unit 1 a signal containing information about the ignition on.

A block diagram of a functional organ blocking device 3 is shown in FIG. This functional organ blocking device 3 comprises a command receiving unit 16, a displacement fact determination unit 17, an information analysis and command generation unit 18, and a switching unit 19 connected to the output of the information analysis and command generating unit 18, to the inputs of which a command receiving unit 16 is connected, and node 17 determining the fact of movement.

The command receiving unit 16 is configured to receive commands from the control unit 1 (command transmitting unit 12). In the considered example of a vehicle (automobile), the command receiving unit 16 receives signals from the on-board vehicle power supply network 8. It consists of a double-circuit bandpass filter with intracapacitance communication with the on-board power supply network 8 and externally capacitive coupling between the circuits, which provides high selectivity and sufficient bandwidth. The signal from such a filter is fed to a frequency detector implemented in the form of a phase locked loop, which ensures high noise immunity.

Node 17 determining the fact of movement is made with the possibility of determining the fact of movement of the vehicle, regardless of the reason for such movement. This node 17 determining the fact of displacement can be completely identical to the node 13 above determining the fact of displacement in the control unit 1, although any other implementation that ensures the proper functioning of this node is quite acceptable.

The node 18 analysis of information and the formation of commands is configured to analyze information received from the node 16 receiving commands from the node 17 determining the fact of movement and from the control unit 1 (from the node 12 transmitting commands) and with the possibility of forming the corresponding commands and issuing them to the node 19 switching. The node 18 of the analysis of information and the formation of commands can be completely identical to the above node 14 of the analysis of information and synthesis of commands in the control unit 1, although any other implementation is quite acceptable, ensuring the proper functioning of this node.

The switching unit 19 is configured to enable or disable the device 3 blocking the functional body. This may be a conventional electromagnetic relay, connected to the respective circuits of the vehicle to block or enable their operation in accordance with the following algorithm of operation of the anti-theft system of the present invention.

The implementation of the claimed method of protecting a vehicle from theft can be illustrated by the operation of the considered anti-theft system in accordance with the algorithm, a block diagram of which is shown in figure 4.

Of course, in the beginning it is necessary to install an anti-theft system on the vehicle (Fig. 1), which includes at least two functional organ blocking devices and is configured to sequentially initiate the operation of each of these functional organ blocking devices. In this case, you must also install each of these devices blocking the functional body on the corresponding functional body in the vehicle.

The algorithm for the operation of the system is illustrated in figure 4.

Accepted in Fig. 4 designations: the variable i denotes the number of the currently locked functional organ blocking device 3. If i = 0, then all the devices 3 lock unlocked, the system is disarmed; if i = 1, then the locking device 3.1 is locked, the remaining 3 locking devices in the system are unlocked, the system is in armed mode; if i = 2, then devices 3.1 and 3.2 are blocked, the system is in armed mode, the rest are unlocked, etc. The variable N represents the number of locking devices 3 in the system. K is a parameter, the meaning of which is clear from further explanations.

Let the system be in the armed state in the initial state, while the control unit 1 sent a command with i = 1: all the locking devices 3 are unlocked, except for the first one (block 20). In this mode, the system expects the following events to occur: activation of input 6 (Fig. 2) (for example, a signal from an external security system or a signal to open a car door), ignition on (input 5 in Fig. 2), operation of the determination unit 13 movement (figure 2), the operation of the node 11 determining the fact of the engine (Figure 2). Parameter K is assigned the value 1 (block 21).

Next, using its own node 15 verification of identifying data or by a signal from an external security system at input 7 (Fig.2), the system checks for authorization. If the authorization is successful, then signals are sent to the switching nodes 19 through all the command transmission units 12 in all locking devices 3 (Fig. 2) with i = 0 (block 30) (“the system is not armed, all locking devices 3 will be unlocked”). This state continues until the input 6 is active (FIG. 2) (block 31) and / or the ignition is turned on (block 32). Then commands with i = 1 are sent (block 33), the system is put into armed mode (block 20).

If authorization has not occurred (NO output in block 22, where authorization is checked), commands are sent with i = К = 1 (block 23), it is checked whether the car is started or not using node 11 to determine the fact of engine operation (Fig. 2) ( block 24). This cycle continues until authorization has occurred (YES output in block 22) or until the car is wound up (NO output in block 24, where it is checked whether the car is wound up using node 11 for determining the fact of engine operation in FIG. 2).

In this mode, the car owner cannot start the engine, since the first lock device 3.1 is locked, and the hijacker can start the car only after finding and eliminating the first lock device 3.1. The remaining devices 3 lock remain unlocked, because i = 1. If the car is started (YES output in block 24), parameter K is increased by 1, commands with i = K = 2 (block 27) are transmitted until the engine is turned off (NO output in block 28, where it is checked whether it has stalled engine), as the second locking device 3.2 is now locked. If authorization is successful in this case, it is also possible to disarm the system (YES output in block 26). After the engine is turned off by the second locking device 3.2 (YES output in block 28), the sequential blocking cycle of the locking device 3 is repeated (YES output in block 28), provided that not all locking devices 3 in the system are blocked yet (NO output in the block 29).

Thus, the algorithm is designed so that the system blocks the next lock device 3. (i + 1) only after the hijacker has removed the previous lock device 3.i.

A feature of the operation of the functional organ blocking device 3.1 is that it blocks the corresponding functional organ 4.1 upon receipt of a command from the control unit 1 with the corresponding parameter i (i≥1). The locking device 3.2 locks the corresponding functional body 4.2, if parameter i≥2, the locking device 3.3 locks its functional body 4.3, if i≥3, etc. and there is a movement of the car, determined by the node 17 determining the fact of movement (figure 3). In this case, the first locking device 3.1 does not have a node 17 determining the fact of movement.

An important consequence of such a device and such an algorithm of the proposed system is that if it is used in conjunction with an external security system (for example, satellite, with the ability to send messages to a control center), the claimed system continues to protect the car in accordance with its algorithm, even if the main (satellite or any other) system is destroyed by the hijacker. This is due to the presence of inputs 5, 6, 7, 8 of the control unit 1, as well as nodes 13, 11 (FIG. 2) and 17 (FIG. 3).

So, if the disconnection of any initiated functional device blocking device 3 occurred unauthorized, for example, the hijacker disconnected the locking device 3.1 installed on functional body 4.1, which is the starter circuit, the anti-theft system initiates the operation of another functional organ blocking device, in this case, device 3.2 , - for example, an ignition blocking device (NO output in block 24).

If an unauthorized (i.e., in the absence of a user authorization signal) disconnection of this functional organ lock device 3.2 occurs, the anti-theft system initiates the operation of the next functional organ lock device, in this case device 3.3, for example, a fuel pump lock device.

Thus, if the information analysis and command synthesis unit 14 in the control unit 1, having not received a signal from the authorization input 7 or from the identification data verification unit 15, receives a signal from the engine operation fact determination unit 11, it will issue a corresponding signal to the command transmission unit 12 , which will send an encoded signal to all devices 3 blocking functional body. However, only the command receiving unit 16 in that device 3 for locking the functional unit to which this signal is intended in accordance with the encoding selected by the information analysis and command synthesis unit 14 will “respond” to this signal. As a result, this functional organ blocking device 3 will block the operation of the functional organ 4 to which it is connected, for example, by closing or opening an electromagnetic relay (i.e., by correspondingly activating the switching unit 19 of this functional organ blocking device 3).

Each time the hijacker restores the operation of the blocked functional unit 4, the control unit 1 initiates the operation of the next device 3 for locking the functional unit at the next start of the vehicle by the hijacker.

If the hijacker manages to destroy the control unit 1 before the engine is started (i.e., before the ignition is turned on for the first time), then the function blocking device 3 of the functional unit, initiated at that time, will actually take over its functions. Such a system operation is possible as one of the options. But if the car starts to move, each device 3 blocking the functional body will determine by its node 17 determining the fact of movement that the car is moving, and, having not received any commands from the control unit 1, will block the corresponding functional body 4 after a certain period of time.

In the absence of a signal from the node 11 determining the fact of engine operation, this fact of engine operation is determined by the presence of ripples in the on-board power supply network. The node 14 for information analysis and synthesis of commands will receive a signal from the node 13 for determining the fact of movement, for example, when towing a vehicle, the node 14 for information analysis and synthesis of commands in the control unit 1 will not issue a command to block the next (in this case, second) device 3.2 blocking a functional organ.

In the operation of the control unit 1 or devices 3 blocking the functional body, you can consider the fact of opening the door of the vehicle by the presence of a signal at the input 6 of the control (see figure 1). Say, in the absence of an authorization signal, the signal at control input 6 will additionally indicate an attempted theft.

In principle, other options can be provided in the vehicle anti-theft method and in the vehicle anti-theft system of the present invention. For example, if a hijacking is detected (opening the door in the absence of an authorization signal, turning on the ignition when the control unit 1 is destroyed, etc.), a warning signal (for example, an audible one) or a message is sent to the security service in the system. An important option is the ability to integrate the claimed anti-theft system into other anti-theft systems, such as satellite anti-theft systems. Then the signal to the control input 6 can come from the satellite anti-theft system, it can also identify the owner with the issuance of identification confirmation for the proposed anti-theft system.

It should be added that if the car was not started in the guard mode and the ignition did not turn on, but the car moves, then the control unit 1 and the functional organ blocking device 3 determine the presence of displacement on its nodes 17 for determining the fact of displacement. The control unit 1, having verified that the vehicle is not started, sends commands to the first locking device 3.1 to remain locked and the rest to remain unlocked.

It is further assumed that when the owner gives the car for service, he puts the security system in a state where all the 3 locking devices are turned off (the so-called service mode), and after carrying out maintenance work puts the system back into working condition.

Thus, the claimed method and system can significantly increase the time required by the hijacker to carry out theft of the vehicle, and reduce the likelihood of negative consequences for the vehicle in case of improper operation. Since the locking devices of a functional organ with numbers 3.2 and higher are not initiated under normal conditions, they can be installed on circuits whose locking under normal conditions can cause damage to the vehicle. This dramatically increases the number of functional organs that can be blocked, which will create additional difficulties for the hijacker.
