Unified vehicle network frame protocol

摘要

A network node module includes a processing module and memory. The processing module is operable to generate a header section of a frame for transmission within a unified vehicle communication network. The header section includes a preamble, routing information, and a vehicle network field, which includes information that identifies a type of the frame. The processing module is further operable to generate a payload section of the frame. The payload section includes data payload and an integrity check field. The processing module is further operable to transmit the frame to the unified vehicle communication network in accordance with a global vehicle network communication protocol.

1. A vehicle communication method comprises:
generating a header section of a frame for transmission within a unified vehicle communication network, wherein the header section includes a preamble, a vehicle network field, and routing information, and wherein the vehicle network field includes information that identifies content types of the frame to include: mission-critical, non-mission critical, vehicle operation and commercial content; generating a payload section of the frame, wherein the payload section includes data payload and an integrity check field; and transmitting the frame to the unified vehicle communication network in accordance with a global vehicle network communication protocol, wherein one or more of the transmissions includes communications outside of the vehicle.
