Abstract

The invention discloses a vehicular Ethernet AVB system. The vehicular Ethernet AVB system comprises vehicular equipment and vehicular network equipment, wherein the vehicular equipment comprises a vehicular circular-view image acquisition unit, a vehicular circular-view image processing unit, a vehicular sound power amplifier unit, a vehicular navigation/entertainment unit, a vehicular instrument unit, a vehicular display unit, a vehicular driving recording unit and a vehicular multimedia antenna unit; and the vehicular network equipment comprises a vehicular Ethernet AVB/CAN network gateway unit and a vehicular CAN bus network transmission unit. AVB protocol transmission based on a vehicular Ethernet is adopted in the invention; compared with the existing various bus transmission schemes, the vehicular Ethernet AVB system disclosed by the invention is obviously improved; and the vehicular Ethernet AVB system is more open in framework, faster in rate and higher in effective load and flexibility.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle-mounted Ethernet AVB system (AVB system for short), and further relates to a vehicle-mounted Ethernet entertainment AVB system. Background technique [0002] Nowadays, the transmission bus used in vehicle communication is mostly CAN bus, but with the continuous improvement of people's entertainment requirements, the existing vehicle communication system can no longer meet people's needs. In vehicle entertainment systems, body control systems, and driver assistance systems The high-definition display and high-bandwidth requirements of high-definition vehicles will become the basis for future vehicle entertainment, control, and information interaction. A new generation of in-vehicle information interaction technology has emerged. Ethernet Audio / Video Bridging (EthernetAudio / VideoBridging, also known as "EthernetAVB", referred to as AVB) is a new IEEE802 standa...
