SYSTEM TO PROTECT VEHICLES AGAINST HIGHJACKING Russian patent published in 2009 - IPC B60R25/10 

FIELD: protection systems.

SUBSTANCE: protection system comprises first electronic mark operating in frequency range of 2400.0 to 2483.5 MHz and second electronic mark operating on frequencies of 125 or 134.2 KHz. There are interlocking modules, each comprising interlocking transceiver operating in frequency range of 2400.0 to 2483.5 MHz, control unit and controlled relay that can be connected to vehicle functional components. It uses indicator unit and readout unit. Control first inputs are connected with ignition bus. Interlocking transceivers allow dynamic identification data exchange with first electronic mark. Second electronic mark allows dynamic identification data exchange with readout unit, while indicator unit allows dynamic identification data exchange with first electronic mark, readout unit and interlocking modules. Thanks to simultaneous use of two ranges of operating frequencies, anti-hijacking system is produced.

EFFECT: higher reliability and ease of operation.
