Vehicle network node module
First Claim
1. A vehicle network node configured to support intra-vehicular operations comprising:
- a plurality of device buffers configured to receive device packets from a plurality of vehicle devices in a vehicle in accordance with a prioritization scheme, at least some of the device packets corresponding to control of the vehicle;
a network buffer configured to receive at least some of the device packets from the plurality of device buffers and output at least some of the device packets to a vehicle network fabric in accordance with the prioritization scheme; and
processing circuitry configured to determine the prioritization scheme based on types of the device packets, wherein the types of the device packets includes at least a vehicle operation packet and a vehicle safety-related mission critical packet, both the vehicle operation packet and the vehicle safety-related mission critical packet for controlling operation of the vehicle and the vehicle safety-related mission critical packet assigned a higher priority of transmission from the network buffer to the vehicle network fabric than the priority of transmission assigned to the vehicle operation packet.

Abstract
A vehicle network node module includes device buffers, a network buffer, a switch circuit, and a processing module. The device buffers temporarily store outgoing device packets from, and temporarily store incoming device packets for, vehicle devices in accordance with a locally managed prioritization scheme. The network buffer receives incoming network packets from, and outputs the outgoing network packets to, a vehicle network fabric in accordance with a global vehicle network protocol. The network buffer also temporarily stores the incoming network packets and the outgoing network packets in accordance with the locally managed prioritization scheme. The switching circuit selectively couples the network buffer to individual ones of the device buffers in accordance with the locally managed prioritization scheme. The processing module interprets the outgoing device packets and the incoming network packets to determine types of packets and determines the locally managed prioritization scheme based on the types of packets.
