Description

The technical solution relates to an electromechanical security device which interrupts a plurality of electric and / or electronic circuits of a motor vehicle, in particular an engine control circuit, and which may include an authorized user biometric identification function. The electromechanical safety device is particularly suitable for retrofitting into already manufactured motor vehicles.

BACKGROUND OF THE INVENTION

Various systems and connections are known which interrupt the electrical or electronic circuits of a motor vehicle to prevent unauthorized use or theft of the vehicle. Series mounted security devices, immobilizers cooperate with the central control unit. Without the appropriate instruction from the central control unit, the vehicle engine is unable to start. The disadvantage of such immobilizers is the consistent standard in an extensive series of vehicles, which always leads to the creation of a uniform procedure to overcome the vehicles of the whole series.

The retrofitted immobilizers and security devices use a box in which different circuits are interrupted, for example by means of relays for each circuit. The relay is controlled by an evaluation unit which switches the relay in case of authentication of the authorized user, for example by means of a contactless key, by entering a PIN and the like. The disadvantage is that the verification process takes place in a device that is stored in the vehicle and is therefore accessible to a potential thief. Another disadvantage is the constant power consumption of the signaling equipment.

US2015217726 discloses a comprehensive security system which also includes fingerprint scanning. The system is complex and is not suitable for retrofitting already in use in motor vehicles. Several patents such as CN106585564, CN206012546, KR20170000908,

US2008030301, discloses fingerprint scanning systems where the scanner is part of a motor vehicle interior.

A security device solution having zero power consumption in the guarding mode that is able to identify the authorized user based on biometric features is desired. The solution should be universally applicable to various motor vehicles.

The essence of the technical solution

The aforementioned drawbacks are substantially eliminated by the electromechanical security device of motor vehicles, in particular for the interruption of electrical and / or electronic circuits, which comprises a removable element according to the present invention, which is based on the removable element having a contact interface with a group of contacts for connection to a plurality of surface contact surfaces in a motor vehicle, the pairs of interior contact surfaces are connected to the electrical and / or electronic circuits of the motor vehicle such that the branch of the electric or electronic circuit of the motor vehicle is interrupted and one end with the first contact of the pair, the second end formed by the break of the branch is connected to the second contact of the pair, the removable element comprising fixed conductive connections which interconnect the pairs of contacts of the respective electrical and / or el. the electronic circuit of a motor vehicle. Thus, within the removable element, the first contact is connected to the second contact of the pair of the respective branch.

The interior surface of a motor vehicle is a location that is accessible to the user of the motor vehicle, usually from the control point. Such a surface shall also be understood to mean a place on a motorcycle or other motor vehicle which does not have an interior designed as an interior space enclosed by the bodywork. The electromechanical safety device according to the present invention is therefore also applicable to motorcycles, tricycles or other motor vehicles. The term surface in the interior of a vehicle is therefore to be understood in this document generally and broadly as a place accessible to the user without special tools, it may also be a space in the luggage compartment.

An essential feature of the present invention is that the removable element comprises a portion of the conductive connection of the individual circuits. Disconnecting the detachable element makes the wiring part, usually the wiring part, incomplete. Thus, an open circuit is not a relay state but is physical. The electromechanical security device according to this technical solution has no evaluation unit placed in the motor vehicle, which brings important technical and safety advantages. In guarding mode, the circuits are disconnected, missing the connection that is made within the removable carrier circuits. In the guarding mode, the electromechanical security device has zero power consumption. The absence of an evaluation unit in the vehicle prevents attempts to overcome its decision algorithm, for example through a service re

S K 8346 žί, through keys that are redefined as justified and the like. The removable element need not have any own power source, such as a battery or accumulator.

The term 'electromechanical' means that the device cooperates with the electrical or electronic circuits of a motor vehicle, mechanically disconnecting them, mechanically dividing them into a section which the authorized user takes from the motor vehicle with him. The electromechanical security device also functions as an immobilizer. The term 'electromechanical' is therefore to be understood in its broadest sense as a connection between a mechanical connector and electrical connections.

The contact interface may take the form of an electrical connector with a sufficient number of contact pairs. In principle, a connector with an odd number of contacts (pins) can also be used, using only an even number of contacts that form pairs to connect the branches of the respective circuits. It is also possible for one input contact of the removable element to be connected to two or more output contacts. In a preferred embodiment, a pair of connectors may also be used that fits into the respective pair of connectors on the interior surface of the motor vehicle. A pair of connectors creates an even number of contacts, but depending on their number, not all contacts can be used for connections inside the removable one.

The interconnections of the first and second contacts of the individual pairs within the removable element may be made by means of wires, cables or preferably by means of a printed circuit board (PCB). Connectors can be soldered to the PCB and the necessary combination of connections will be created on the PCB's conductive paths. This also makes it possible to easily create different combinations of connections within the removable element. PCBs for detachable elements of various electromechanical security devices will be created as individual designs, for which a computer program with gradual or random generation of combinations can serve. The code of the detachable element in such an arrangement is stored in the graphic of the conductive connections to the PCB, but this does not present a safety risk because the code is not accessible in the vehicle device. At the same time, it is possible to cover the PCB with an opaque layer after establishing the conductive connections, so that even after removing the detachable element it is not possible to read the connection scheme of the first and second contacts of individual pairs.

In the manufacture of the electromechanical interlocking device of the present invention, a high number of unique interconnections can be made, i.e. the removable element i of the electromechanical interlocking devices of different vehicles has different arrangement of pairs of first and second contacts within the contact interface. In practice, this means in particular that the first and second contacts of one pair have a different position for each motor vehicle within the geometry of the connector or several connectors. As the number of contacts used increases, the number of available combinations increases exponentially.

Another advantage of the present invention is that the contact interfaces, for example in the form of a conventional connector, are capable of carrying relatively high current loads. As a result, the removable element is capable of directly switching on and off the power circuits, no relays that are commonly used in electronic immobilizers are required. The relays are not only a power consumer but can also be a source of faults.

The device according to the invention may also comprise an element for blocking the removable element in the connection position of the contact interface. This blocking element ensures that the contact interface does not trip by mistake or vibration while driving. The locking element may be in the form of an electromagnetic lock that mechanically blocks the ejection of the connector, or may prevent gripping of the removable element and the like.

The removable element according to the present invention may, in a preferred embodiment, also comprise a biometric sensor which is connected to the opening control. The biometric sensor is only activated after the removable element has been inserted into the contact interface, so even in this embodiment, the removable element need not have any battery, accumulator or similar power source. The biometric sensor can connect conductive connections directly or via relays. Usually, the relay will only be used on one branch that does not require a high current load.

An arrangement in which the biometric sensor is a fingerprint sensor or a fingerprint sensor has proven advantageous. fingers. The fingerprint sensor may be located on the removable member at a location that corresponds to the finger position, for example, the thumb while holding and handling the removable member. When the removable member is inserted into the contact interface, the fingerprint sensor is activated. The user holds the finger on the sensor and, after reading the fingerprint, can move the hand away from the removable element. The removable element may be provided with a light signal so that the user can see when the fingerprint reading is complete.

An essential advantage of embodiments with a biometric sensor, in particular a fingerprint sensor, is to eliminate the risk that the removable element will be stolen from the authorized user and the motor vehicle will be used with the original removable element but without the authorized user's consent. It is advantageous to place the biometric sensor in the body of the removable element. By examining a motor vehicle in the inactive state, it cannot be established that the securing device also includes a biometric sensor. It is also an advantage that when retrofitting in a vehicle, it is not necessary to place the biometric sensor on an interior surface, for example in the dashboard, which simplifies assembly. The biometric sensor in the removable element in the inactive state, ie outside the connection to the contact interface in the vehicle, does not remove any

S K 8346 Shields electrical energy. By handling in a motor vehicle without a removable element, the authorized user's biometric data profile cannot be ascertained as it is stored in the removable element.

In a preferred embodiment, the fingerprint sensor will be positioned within the removable element at a location that corresponds to the finger position while naturally holding the removable element. Typically, the finger to be scanned will be the thumb, and the position of the fingerprint reader will correspond to the location of the thumb while holding the particular shape of the removable member. The shape of the removable element can be ergonomically designed to assist in a natural and easy grip between two or three fingers.

In order that the removable element does not protrude all the way into the interior of the motor vehicle, it will be appropriate if the contacts for connection to the contact interface are located inside the shaft of the motor vehicle. The shaft has a cavity adapted to receive the removable element. By means of a manhole, the device can be appropriately designed to act as a non-intrusive interior and does not protrude outward, for example out of the dashboard surface, which by its outer contour forms the interior surface. In order to enhance both user and aesthetic properties, the shaft can be provided with illumination, preferably illumination, the color of which can be adjusted according to the color of the lighting of a particular motor vehicle. Lighting will facilitate the insertion of the removable element in the dark. At the same time, the lighting of the shaft or also lighting within the removable element can serve to identify the activated or unlocked state of the device. For example, the shaft may glow red when the device is in a guarded state, and green if the device is deactivated, an authorized user's fingerprint, etc., is taken.

In order to enhance the user functions, the electromechanical security device according to this invention can be supplemented with a GPS module which detects the position of the motor vehicle. The electromechanical interlocking device according to this technical solution can also cooperate with the GPS module, which was already part of the motor vehicle before the assembly of the electromechanical interlocking device, while being connected to the shaft. The GPS module is located within the motor vehicle, not bound to the removable element, but cooperates with it, for example, so that the GPS module is able to identify whether the removable element is inserted and interconnects the electrical or electronic circuits of the motor vehicle. The GPS module may be connected to a wireless communication module, for example a GSM or GPRS communication module, through which current position and condition data of a motor vehicle are sent. If a biometric sensor is used within the removable element, the communication module can also send driver identity messages. The electromechanical securing device according to this technical solution can also serve for creating a logbook in such an embodiment.

The branches which are interrupted by the device according to the present invention may be part of any electrical or electronic system of the motor vehicle. Usually this will be the connection between the engine and its control unit, between the sensors and the control unit. It may also be a transmission circuit, preferably an automatic transmission, unlocking the electrically operated handbrake, controlling the starter, the fuel pump, the booster, and the like.

An important advantage of the present technical solution is the high reliability and safety of the device. The use of a biometric sensor also eliminates the risk of a motor vehicle being abducted and, for example, misused for terrorist attacks. Although the motor vehicle itself does not provide any indication of biometric identification on the outside, it is not possible to start the vehicle after unauthorized theft or robbery, even if the vehicle has an original detachable component. is part of the removable element.

The present invention has a simple and operationally reliable construction, is capable of carrying a high current load directly and has no power consumption in the activated state. It is also advantageous that the device code based on the particular geometry of the conductive connections can be detected with the participation of the detachable element and the dismantling of the components in the vehicle.
