Problems solved by technology

[0002] The traditional automotive Ethernet architecture only uses a single controller (electronic control unit, ECU), single gateway, and low-speed automotive Ethernet, which limits the transmission of high-speed data streams and increases the load on the gateway and ECU
[0003] In the traditional connection method, the wiring harness is too long and must be directly connected according to the function; for example, multiple surround-view cameras must be connected to the same ECU. Due to the different installation positions, the bus length of the cameras at the two ends is equal to the length of the vehicle.
[0004] Moreover, the central layout makes the ECU and gateway have extremely high requirements for operating failures, and is not suitable for long-term and complicated working conditions of vehicles.

Abstract

The invention discloses a vehicle-mounted Ethernet architecture compatible with a TSN and introducing an FC protocol, and the architecture comprises a first central control unit and a second central control unit, and the first central control unit and the second central control unit communicate with each other through the FC protocol; the first central control unit is connected with a first domaincontrol unit and a second domain control unit, and the first domain control unit and the second domain control unit are communicated through a TSN protocol; the second central control unit is connected with a third domain control unit and a fourth domain control unit, and the third domain control unit and the fourth domain control unit are communicated through a TSN protocol; the first domain control unit and the third domain control unit are communicated through a TSN protocol; and the second domain control unit and the fourth domain control unit are communicated through a TSN protocol.

Description

technical field [0001] This application relates to the field of vehicular Ethernet communication, in particular to a vehicular Ethernet network architecture compatible with TSN and introducing FC protocol. Background technique [0002] The traditional automotive Ethernet architecture only uses a single controller (Electronic Control Unit, ECU), single gateway, and low-speed automotive Ethernet, which limits the transmission of high-speed data streams and increases the load on the gateway and ECU. [0003] In the traditional connection method, the wiring harness is too long and must be directly connected according to the function; for example, multiple surround-view cameras must be connected to the same ECU. Due to the different installation positions, the bus length of the cameras at the two ends is equal to the length of the vehicle. [0004] Moreover, the central layout makes the ECU and gateway have extremely high requirements for operating failures, and is not suitable f...
