ES2226555A1 - Electronic immobilizer for vehicle, has electronic circuit board equipped with card reader, and clock equipped in electronic circuit for preventing passage of current to deactivate starter engine until reader returns to read card - Google Patents

Abstract

The Immobilizer has an electronic circuit board (1) equipped with a card reader. A card activates the electronic circuit board. A chip (4) in the electronic circuit board connected with a closed relay (5) to pass current for activating a starter engine of a vehicle. A clock (2) is equipped in the electronic circuit board for preventing the passage of the current to deactivate the starter engine until the reader returns to read another card.

Description

Electronic vehicle immobilizer through coded tab reader.

Technical sector

The invention falls within the sector of Automotive

State of the art

Currently within the automotive sector and more  specifically in the mandatory insurance, there is no system that prevents driving a vehicle that lacks insurance required.

It could also be applied to any means of locomotion that requires the obligation to own insurance.

Detailed explanation of the invention.

The present invention relates to a reader of code sheet (6) which, when read, activates an electronic circuit (1) programmed for a year to close the circuit of a relay (5) allowing starter motor operation of the vehicle (10).

It basically consists of a card reader (6) encoded (8) that activates a chip (4) which puts in operation of an electronic clock (2) programmed so that Run for a year.

The electronic clock (2), although the engine is off, still working when a battery (3) is incorporated Estimated duration is about 15.

\hbox{(10)-,}

quedando cerrado el circuito de éste cada vez que se accione la llave de contacto (9), de forma que la corriente pasa a través de él y llega al motor de arranque (10), poniéndose en marcha el motor del vehículo.The chip (4) activates a relay (5) of 20 amps - intensity required by the starter motor

 \ hbox {(10) -,} 

the circuit of the latter being closed each time the ignition key (9) is operated, so that the current passes through it and reaches the starter motor (10), starting the vehicle engine.

After one year, the clock (2) deactivates the entire circuit (1), leaving the circuit of the relay (5) and preventing the passage of the current coming from the ignition key (9) and goes to the starter motor (10).

Next to the reader of the code sheet (6) a LED (7) is placed, which when the system is activated with the reading of the code sheet (8) turns on, acquiring a green color; When eleven months have elapsed -11- it changes to a flashing red light and once the 12 months have elapsed - time of validity of the insurance - the LED goes out.

The electronic circuit (1) is installed after the dashboard -imposing its manipulation-, except the reader of tab (6) and the led (7).

The ignition key (9) of the vehicle has a starter motor output (10); between the two is sandwiched this electronic circuit (1) - together with the card reader (6) -.

The electronic circuit (1) acts directly on the starter motor (10); if the vehicle is driving in the moment your insurance expires, this circumstance will not cause the vehicle stop at that time. When cutting the ignition, when the driver try to start again, the starter motor (10) does not it will work.

Brief description of the drawings

For the best understanding of how much is left described herein, some drawings are attached in the that just as an example is a case study of realization of the immobilizer.

In the drawing on page 7, figure 1 represents the electronic circuit - whose measurements are 5.5 x 5.5cm which is installed inside the dashboard and to which the starter key -figure 3-, the starter -figure 4- and the tab reader -figure 2-.

Between the key and the starter motor goes interleaved the electronic circuit.

The reader and the LED are installed in an area visible on the dashboard, indicating the status LED with its color of the circuit

The drawing on page 8 - Figure 5- represents The electronic components of the circuit.

Operating procedure of the vehicle immobilizer by means of an encoded card reader , according to claims 1 and 2, characterized by the following steps:

- The reader (6) reads the file (8), activating the circuit (1) for one year.

- The ignition key (9) of the vehicle has a  starter motor output (10). Between them, the electronic circuit (1), which, by means of the relay (5) that carries built-in, leaves the current flow that is open or closed feed the starter motor (10).

- Since the electronic circuit (1) acts directly on the starter motor (10), there is NO risk that due to this circuit (1) the motor will stop involuntarily.

Claims (2)

1. Electronic vehicle immobilizer by  coded token reader (6), composed of a token reader coded (6), a tricolor led (7), an electronic circuit (1) which incorporates an electronic clock (2) powered by a battery (3) built into it, a chip (4) programmed to Run for one year and one relay output (5). 2. Electronic vehicle immobilizer by means of an encoded card reader (6) (8) characterized in that when the reader (6) reads the card (8), the clock (2) is activated, which through the chip (4) makes that the relay (5) close its circuit, allowing the passage of the current that drives the starter motor (10). The reader (6) will only read that file (8) whose code matches yours, and once it has been read, it remains unused On the dashboard, next to the reader (6) goes installed a led (7) that for 11 months gives a green light  changing from that moment to flashing red and turning off at 12 months, so the circuit (1) is disconnected - leaving the relay circuit (5) open which prevents it from reaching starter motor current (10) -. By reading a new file (8) you reactivate the device for another year.
