Abstract
A vehicle-control communication system, in which a plurality of control function units such as ECI (engine control) are separated into an I/O processing function and an operation control function, and the I/O processing function for each control function unit comprises I/O processing nodes, while the operation control function is formed as one of the operation control nodes for each of vehicle control groups each obtained by integrating control function units with a relation therebetween into one group. Transmit-receive of information within each of the vehicle control groups is executed via any of first communication lines, while transmit-receive of information between the vehicle control groups is executed via a second communication line.
