VEHICLE SECURITY SYSTEM REMOTE CONTROLLED RELAY Russian patent published in 2007 - IPC B60R25/00 

FIELD: transport engineering.

SUBSTANCE: invention is designed to protect automobiles from unauthorized use. Proposed remote controlled relay is controlled by central control unit in standard on-board circuit of automobile. Remote controlled relay contains motion sensor unit, delay element and electromechanical relay. Contacts of relay are designed for connection to functional members of automobile and to alarm signaling units. Motion sensor unit includes horizontal motion sensor on base of two-coordinate accelerometer and vertical motion sensor on base of one-coordinate accelerometer. Remote controlled relay includes also microprocessor and self-contained supply and control unit. Input of the latter is connected to supply bus, first output, to first control, input of microprocessor and second output is connected to microprocessor supply input and through relay winding, with functional input of microprocessor. First and second signal inputs of microprocessor are connected to first and second coordinate outputs of horizontal motion sensor, third signal input is connected to output of vertical motion sensor, and second control input is connected to output of delay element. Delay element is connected, through supply bus and ignition switch, to automobile storage battery. Proposed remote controlled relay provides both antitheft protection and alarm signaling at horizontal and vertical movements of vehicle.

EFFECT: provision of warning signals (sound, light or radio ones) at any movements of automobile, irrespective of switching on or off of ignition system.
