VEHICLE COMMUNICATION NETWORK INCLUDING WIRELESS COMMUNICATIONS

摘要

A wired and wireless vehicle communication network includes network node modules, switch modules, bridge-routing modules, and a network manager. The network manager is operable to determine a wired packet communication mode and/or a wireless packet communication mode. When the network is in the wireless packet communication mode, the network manager coordinates wireless communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on individual content of the packets and wireless channel mapping. When the network is in the wired packet communication mode, the network manager coordinates wired communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on the individual content of the packets and in accordance with a global vehicle network communication protocol.
