ELECTRIC VEHICLE DOMAIN ARCHITECTURE VEHICLE NETWORK SYSTEM, DOMAIN COLLABORATIVE PROCESSING METHOD AND DOMAIN CONTROL DEVICE

摘要

The present invention relates to the technical field of electric vehicles, in particular to a domain architecture vehicle network system, a domain collaborative processing method and a domain control device of an electric vehicle, comprising an on-board switching device, an on-board backbone network, an energy domain control device and sub network system thereof, a power chassis domain control device and sub network system thereof, a vehicle body domain control device and sub network system thereof, an intelligent/auxiliary driving domain control device and sub network system thereof, and an infotainment domain control device and sub network system thereof; the on-board switch device is connected to each domain control device by means of the on-board backbone network, and each domain control device is connected to the system thereof in a domain by means of the respective on-board sub networks; the on-board switching device manages interactions of each domain control device using the domain collaborative processing method, thus achieving the implementation of cross domain functions. The present invention can obviously improve the implementability of vehicle multi-function system integration, while effectively inhibiting network congestion and delay problems, and improving the reliability and real-time performance of vehicle control.
