Abstract

The invention relates to an anti-theft security system for any vehicle, in which only original or optional components provided in the passenger compartment of the vehicle are used in order to introduce the key, without adding to or altering said passenger compartment in any way. The key is introduced using the components provided in the passenger compartment, one of the effects thereof being to change the voltage at some point of the electric circuit of the vehicle. Once introduced, the key is identified by an identifier circuit installed inside the vehicle. Said identifier circuit interrupts the electric circuit at one or more points that are critical for starting the vehicle. The identifier circuit is only deactivated when the key is introduced in the order programmed by the owner, thereby allowing the engine and thus the vehicle to start.

Description

Anti-theft system for vehicles activated by voltage changes, by executing actions on the original and optional components, provided in the vehicle's interior.

The present application refers to an antlrmbo security system for any vehicle class, in which, to enter the key, it uses only the original or optional component components provided in the vehicle interior, without adding or altering in any way said cabin

The introduction of the key is generated by using those operable components provided in the passenger compartment, in a predetermined order by the owner, which have as one of its effects the change of voltage at some point in the electrical circuit of the vehicle.

Once this key is introduced, only in the order previously determined by the owner, a circuit identified "that interrupts the electrical circuit of the vehicle at one or more critical points for the arrival of the vehicle, through dry contacts or semiconductors, It is deactivated allowing the engine to start and therefore the vehicle.

State of the Art

At present there are several systems that prevent the total theft of a vehicle, the strategies for achieved are diverse and can be classified into five categories.

The first is mechanical, and consists of a visible solution based on obstacles that prevent the use of the handlebar, the gearbox or the accelerator .. Its mechanical operation requires additional keys _. , being in many cases a factor that hinders the departure of the vehicle even for its own owner. On the other hand, this solution is visible and generates a deterrent effect that the antisocial perceives as an additional difficulty, which in some cases allows it to seek an easier-to-address alternative. Its weakness lies precisely at that point, since by being visible the antisocials have developed ways to violate its effectiveness and the press has spread that those antisocials who know how to break the sheet or open it take between three to five minutes to do so.

The second refers to those systems that interrupt the starting motor through a hidden switch. This method has become popular and has been dubbed "breakers" for this reason, however its biggest weakness is that by interrupting only the starting engine, antisocials can steal the vehicle by finding the switch or simply by packing the car by putting the box of changes in neutral. The third refers to those systems that use the alarm signal or central locking so that a switch that is inside the cabin is activated by means of a relay, This system generates the same type of safety as the "current cutter" and by therefore it has the same weakness when pushing the car also consumes battery power while the vehicle's engine is off since it needs a receiver that can capture the coded serial, so it is active, a subject that is not indifferent to the brands at the moment gives homolog to the system.

The fourth refers to those systems where the vehicle key has a "chip" with a unique binary code that enables the vehicle to start when it is inserted into the key slot. Its main weakness is that it depends on the key, so if it is stolen or stolen from the owner, the vehicle can easily be stolen as well. On the other hand, if for some reason the chip would break down, a copy should be requested from the manufacturer in the country of origin. This entails high costs and delays that can be annoying for the owners.

Finally, there are those systems that use a programmable microcontroller (PIC) and a numeric keypad that allows you to generate a security code like the one you have with the bank cards. Such a system does deliver a solution that can interrupt more than one starting source for the motor (unlike the current cutters) tends to be sensitive to static energy, so that failures that prevent even its own owners have been observed , the use of their vehicles. The only way to correct the problem is to change the damaged device for a new one with the cost in money and time that this generates for the owner.

A final dilemma that the procedures described have is that they are designed for antisocials with a culture different from the local one. Therefore, although their solution may be efficient for the culture that designed them, they do not necessarily respond to domestic needs.

The solution proposed in this application is based on the objective of generating a procedure that does not depend on components other than those of the original vehicle configuration. That is passive (do not use battery power while the vehicle's engine is off), low cost and that responds to the needs of our culture. Being a new technique that assures the owner of a vehicle that it will not be stolen while it is parked and that the security depends on the interaction that it has with the existing components inside the cabin where the appearance or disappearance is obtained as a result of voltage at some point in the electrical circuit of said vehicle.

Therefore, the system consists in the generation of a sequence from the original and optional aoeionabíes components of the vehicle to generate an invisible key that allows the security of any device outside the vehicle to be released and to transfer the security to the owner of the vehicle or to whom it I want you to drive it. It will be understood as optional sectional components to those components such as electric windows, around conditioning, radio, automatic transmission, cruise control etc., that is to say those components that the owner chooses to voluntarily incorporate into his vehicle.

The key will be encoded through an electronic circuit, which is installed, however, as the result of said coding can be achieved in various ways, the circuit does not constitute a contribution to the electronic state of the art, but a means to achieve the safety of the vehicle that uses the components to secure said asset.

The main advantages of the system are, for this reason, being invisible to the eyes of the antisocial and on the other hand being passive (do not use battery power while the vehicle's engine is turned off). This eliminates those foreign components that generate insecurity by depositing their viability in components that can be stolen or stolen from the owner.

Brief Description of the Figures

Figure 1: Graphical representation of the interior of a vehicle with its most representative components.

Figure 2: Components described for example 1 of the interaction between the key identification circuit generated through a sequence from the original and optional vehicle components.

Figure 3: Graphical representation showing the three parts of the system in the form of related sets.

With reference to the figures, Figure 1 is a scheme representing the components described through numbers 1 to 26. However, more optional components could be installed that can serve as a source for the potential key.

Figure 2 is a diagram showing the interaction of the vehicle contact switch with the components that can be used to generate a key from the change in voltage they produce. The key components show that the mechanical element where the owner executes an action has, in turn, an electrical derivative that generates a voltage change. Said derivative is the one that the identifying circuit recognizes when the voltage changes, but it needs the mechanical component so that the action can be executed by the owner. Figure 3 is. a scheme that seeks to exemplify the system in three subsets, where A represents it to all existing components within the interior of a vehicle; B to the identifying circuit that blocks the start of the vehicle's engine until the key is properly entered and C the critical points that could potentially be interrupted in the vehicle's electrical circuit. The black zone represents that portion of the components chosen by the owner of the vehicle that are recognized by the identifier circuit, which when executed in the order previously defined by it, cancel the interruption of the critical points of the vehicle's electrical circuit, thus allowing the Vehicle engine start.

Detailed Description of the Invention,

An anti-theft security system for any vehicle in which, to enter the key, only the original or optional actionable components provided in the passenger compartment for driving the vehicle are used, without adding or altering in any way said passenger compartment. It consists of:

A. - A set of electrical signals, in the form of voltage, that come from the original or optional components of a vehicle, as detailed in paragraph nine of the "State of the art", constituting the source from which the power will be generated. key that each owner will choose, enabling the engine to start if he properly executes said personal key. This set of electrical signals are described in Figure 1 numbered from 1 to 25. (1) represents the front electric glass lifts; (2) represents the rear electric glass hikes; (3) represents the position controller of the external rearview mirrors; (4) represents the switch of the foggers; (5) represents traction control; (6) represents the controller of the position and shape of the seats; (7) represents the horn or horn; (8) represents whether switch of interior lights; (9) represents the brake pedal; (10) represents the handbrake indicator; (11) represents the cigarette lighter switch; (12) represents the fan switch; (13) represents the indicator of changes; (14) represents the radio power on command; (15) represents when extracting cassette or "CD"; (18) represents the "defrost" command of the rear glass; (17) represents emergency lights; (18) represents the switch of the conditioned conditioner; (19) represents the turn signaling controller; (20) represents the seat belt indicator; (21) represents the low light switch: (22) represents the high light switch; (23) represents the windshield wiper switch; (24) represents the remote control of the central locking; (25) represents the alarm remote control.

It also interacts with the battery (28) which is the power source of the system and with the contact switch (27) that enables the electrical commands to enter the key,

B. - An electronic identifier circuit (28) that interprets said voltage changes and the order in which they have been introduced. The programming of said circuit identifier It can be generated by an electromechanical device included in it or by software that interacts with the circuit identified. This order is programmed by the owner.

C.- The interruption of the electrical circuit of the vehicle at one or more points, critical for the starting of the vehicle, such as the starting motor solenoid, fuel injectors, fuel pump or others through dry contacts or semiconductors.

System application example: Describes the set of original and optional components from which the owner can choose his password.

Example 1

In the case represented in Figure 2, the actions of: squeezing the brake, running the linipiaparabrlsaa and honking the horn have been chosen. It must be made explicit that the patent application is not made by the use of the three specific actions indicated in this example, but by all the actions that exist or may exist in a vehicle and whose execution has as one of its results the change of the voltage with which the vehicle operates, or a derivative of it, that exists at some point in the electrical circuit of the vehicle.

As mentioned in the description of example 1, in this case the actions taken on the following three components have been taken as a key to start the engine of a vehicle: a) press the brake pedal (9) - start the brake lights;

b) move the lever to run the windshield wiper (23) - operation of the corresponding motor and

c) tighten the part of the handlebar that activates the horn (7) - horn activation

Once these actions have been executed in the order programmed by the owner and, therefore. When the key has been entered correctly, the electronic identification circuit (28) is deactivated, allowing the engine to start and therefore the vehicle.
