Description

The invention relates to the field of transport, in particular anti-theft systems and electronic keys of self-propelled vehicles.

Most of the cars produced in the world for protection against theft and ease of use are equipped with immobilizers or keyless entry systems.

According to the information of the site "Behind the wheel" https://www.zr.ru/.

Immobilizer (https://wiki.zr.ru/ Immobilizer) is a device that prevents the car from moving on its own when trying to start it unauthorized. The effect is achieved by blocking the vital circuits of the car - ignition circuits, starter and fuel pump. Typically, an immobilizer consists of three main parts: a control unit from which control signals are received; relays that break the circuit and the key with the transponder, which is recognized by the control unit.

Keyless access (https://wiki.zr.ru/ Keyless access) is a system for accessing a car using a special electronic card, the so-called smart key. The car computer at a short distance exchanges codes with a smart key, identifies it and gives a command to open the doors. When removed for a distance, the computer loses the smart key from sight and locks the car. Smart keys can be made in the form of a card, bracelet or have a different shape.

However, according to the data of the portal auto.mail.ru https://auto.mail.ru/article/63823-eksperty_nazvali_samye_populyarnye_sposoby_vzloma_avtomobilei/ with reference to the Caesar Satellite JSC, the above systems ceased to provide protection against theft due to the widespread use of the so-called extension cords key "-" fishing rods ".

Such a criminal tool consists of two relay modules - the receiving and transmitting. The receiving module must be located at the vehicle, transmitting at the key. After the system is turned on, a high-speed digital data channel is installed between the modules, which allows relaying the car’s requests to the key and vice versa.

The present invention aims to make impossible the criminal use of any regular key repeaters.

This goal is achieved by complementing the design of standard keys with a transponder and smart keys with a transponder with mechanically controlled switches that break the electrical circuits (power, antenna and processor) of the electronic key. At the same time, the operability of the key transponder and other service functions performed by the key (smart key) become available only at the request of the owner.

To ensure durability and reliability, contact groups of the circuit breaker, electronic components and key batteries should be protected against moisture.

Mode of application

Having left the salon in an unsafe (public place), the owner can turn off the electronic components of the standard key (smart key) using the switch on his case.

After that, the receiver of the immobilizer and the standard car alarm system, without detecting the signal from the transponder, blocks the car door and makes it impossible to start the engine.

If it is necessary to use a vehicle, the owner must turn on the key, which will allow the car computer to detect the transponder and, in turn, open the doors and start the engine.

The advantages of the invention

1. Protects against criminal use of any regular key repeaters.

2. Does not require investments in expensive research and development.

3. It can be implemented immediately and used until the development of more reliable electronic security systems or in parallel with those.

4. It can be applied to any self-propelled vehicles.

Claims (1)

Safe vehicle electronic key, characterized by the presence of a hand-sealed switch that breaks the electronic circuit of the electronic key.
