VEHICLE SECURITY SYSTEM Russian patent published in 2005 - IPC

FIELD: transport engineering; security systems.

SUBSTANCE: invention is designed to protect vehicle from unauthorized use. User remote identification unit consists of vehicle-mounted part and carry-on part connected with processor unit whose control input is connected with supply bus through ignition switch. Display unit input is connected to first output of processor unit. Each functional member locking unit contains series-connected first matching unit whose input is connected by communication channel to second output of processor unit, decoder, memory element and relay connected through contact groups to functional member to be inter locked, and also series-connected relay contact group test unit, nonvolatile memory, coder and second matching unit whose output is connected to first input of processor unit by communication channel. Delay element and movement sensor are connected to corresponding inputs of memory unit. Input of delay element and contact groups of relay are connected to supply input of processor unit. Second output of nonvolatile memory is connected to second input of processor unit. Display unit is made for receiving signals from processor unit indicating provision of jumper parallel to contact group of relay.

EFFECT: improved efficiency of protection of vehicle owing to possibility of detection concealed jumpers installed in interlock circuits of functional members.
