Research and Design on Lightweight Automotive Ethernet FQTSS Protocol

摘要

In view of the problem that the current automotive Ethernet AVB protocol stack cannot fully adapt to the vehicle network environment, optimization about the FQTSS protocol in Ethernet AVB is focused on in this paper. Considering the status of current automotive Ethernet AVB protocols stack is conservative, a lightweight Ethernet AVB platform is designed and implemented in this paper. With reference to the relevant standards and specifications given by the AVnu Alliance, a hardware test platform based on STM32 is built. Then, combined with the improved LwIP protocol stack and μC/OS-II operating system, a solution about low-cost, low-overhead, low-latency lightweight automotive Ethernet FQTSS protocol is proposed and implemented. Finally, some necessary test is executed to verify the feasibility of the solution.
