VEHICLE CONTROLLER Russian patent published in 2002 - IPC

FIELD: transport engineering; electrical and electronic equipment of vehicles. SUBSTANCE: controller includes interface module and modules of engine, instrument cluster, left-hand, right-hand front and rear doors, trunk, steering column and central control unit and also carried-on computer and test system. Interface module is made with four-conductor bus. One pair of conductors is supply one, and other pair serves to transmit data and it is furnished with CAN-junctions. Each functional module has central processor coupled through individual CAN-junction with CAN-junctions of interface module and is connected by inputs of auxiliary contacts and limit switches of vehicle actuating members, mode parameter pickups and by outputs, to pilot lamps, instruments, indicators and actuating members of vehicle. Computer is made for showing vehicle mode parameters on display, and test system is designed for detecting and indicating failure of coupling of module of central control unit with other modules. EFFECT: improved efficiency of vehicles controller and optimum operation of vehicle mechanisms and sets. 9 cl, 11 dwg
