VEHICLE DATA CONTROL SYSTEM

FIELD: transport engineering; security systems. ^ SUBSTANCE: invention relates to protection of vehicles against unauthorized action and control. Standard electronic modules connected to vehicle supply bus are coupled with vehicle functional members and provide checking of state and control of vehicle functional members. System includes local data network controller, of data exchange protocol, external radio network terminal and security lo-jack subsystem. The latter includes controller connected to vehicle supply bus, electronic modules connected to corresponding functional members of vehicle and remote identification unit coupled by radio with vehicle-mounted and carry-on parts. System includes control PLC-unit consisting of PLC-controller, PLC-transceiver and PLC-adapter connected with vehicle supply bus. PLC-modes are built into standard electronic modules, controller and electronic modules of security lo-jack subsystem, each PLC-modem being coupled with vehicle supply bus. Controller-converter of data exchange protocol and controller of vehicle local data network are made for data exchanger with PLC-controller. ^ EFFECT: provision of high degree of vehicle protection, possibility of control of service devices, ease of mounting and connecting of nonstandard electronic equipment to standard equipment of vehicle. ^ 4 cl, 3 dwg
