Description

Technical Field

[0001] The utility model relates to a vehicle-mounted electronic and electrical architecture, and in particular to an automotive electronic and electrical architecture system based on optical fiber Ethernet. Background Art

[0002] As automotive technology continues to advance, the functions of automobiles continue to increase, resulting in a sharp increase in the number of sensors and ECUs, which in turn increases data transmission exponentially. In the automotive high-end ADAS system, 5 to 10 high-definition cameras, 2 laser radars, and 4 millimeter-wave radars are used, making the transmission rate per second less than 10G / s. The existing electronic and electrical architecture mainly uses CAN and LIN. As we all know, the transmission rate of CAN and LIN is very low, only a few M transmissions, so it cannot meet the requirements. Therefore, IEEE proposed an automotive Ethernet solution based on copper wire as the medium, but the Ethernet transmission solution based on copper wire has a high cost for transmission greater than 1G, and needs to overcome EMI, which increases the difficulty and cost of research and development. In transmission scenarios greater than 10G, the cost of Ethernet transmission based on copper wire is higher, and it is more difficult to overcome EMI, and the low signal-to-noise ratio leads to an increase in bit error rate.
