车控操作系统实时性/安全性保障技术

Electronic control technology continues to enable the rapid development of intelligent connected vehicles, and the vehicle control operating system is the fundament of ensuring the safe, efficient, and real-time operation of the electronic control software of automobiles. As intelligent connected vehicles develop towards centralized and end-cloud integrated electronic and electrical architecture, vehicle-mounted hardware evolves into multi-core heterogeneous processors and elastic computing platforms, and vehicle control software transforms into service-oriented software architecture. The architecture and key technologies of vehicle control operating systems also develop accordingly. In this article, the development and current situation of vehicle control operating systems for intelligent connected vehicles were reviewed, and the basic theories and key technologies of task scheduling, real-time performance/security guarantee, and formalized representation and verification were analyzed. The technical challenges and development trends of the existing vehicle control operating system were discussed, so as to provide a reference for the development of the vehicle control operating system of intelligent networked vehicles.
