智能新能源汽车车载控制基础软硬件关键技术研究进展

The intelligence and networking of new energy vehicles have put forward higher requirements for the basic software and hardware of vehicle on-board control including core control chips，operating systems and networks，which must meet disruptive needs such as high-performance computing，high security control and big data communication. Focusing on the high reliability and safety design requirements of vehicle core control chips，vehicle control operating systems，and high-speed distributed fiber optic communication in vehicles，this paper introduces the latest research on key technologies of the architecture of vehicle control operating systems and vehicle core control chips that support intelligent control algorithms under complex driving conditions，the high reliability design technology and environmental adaptability enhancement technology of vehicle core control chips under harsh working conditions，functional safety design and guarantee technology for vehicle control operating system and on-board core control chip，control signal transmission tool based on high-speed distributed fiber optic communication technology，and communication protocol fault diagnosis and self testing technology. Based on the above research results，the independently developed vehicle core control chip and vehicle control operating system have all passed practical vehicle verification. The established research and development system for technology breakthrough，product development，standard formulation，and practical vehicle verification can provide necessary theoretical and technical support for the complete autonomy and controllability of the basic software and hardware of intelligent new energy vehicle on-board control in China.
