The conventional vehicle electric/electronic system architecture has become an obstacle of the booming development of in-vehicle electric and electronic devices. The surging number of these devices and the runup of the information exchange requirement among the devices call for a brand new system architecture.
In this paper, a completely distributed electric/electronic system architecture with a centralized coordinator is introduced. The new architecture concept features a set of hierarchy on-site serial buses together with a digitalized power supply network coordinated by a central controller. The basic functionality and diagnosis of all the in-vehicle electric devices are implemented as digitalized nodes with unified connection interface in the network, which execute commands and share information with the central coordinator.
The new architecture facilitates the information exchange, minimizes the cost and effort of vehicle harness, and reserves the configurability and expandability. The distributed structure with twin backup central coordinators ensures the system reliability.
