A Hybrid Operating System Platform For Intelligent Connected Vehicle

With the development of automobile industry,automobile electronic system type system involves more complex methods to separate,traditional system architecture has gradually exposed system architecture is not unified,drawbacks of code reuse.This paper presents a hybrid operating system platform named SAOS(Smart AUTO OS)and presents the SAOS Studio,which is the development tool for SAOS tasks,the mainly characters of SAOS as follow:(1)Different types of tasks will be intelligently deployed to different platforms,has different runtime environments and task scheduling strategy,and developers only need to mark the task as Real-Time Control tasks,Human-Computer Interaction tasks and High Computing tasks according to its type of business,real-time and computing.(2)The system has good bus compatibility.The system supports the TSN protocol for transmitting audio and video,has huge bandwidth and good real-time performance,and can meet the new requirements of the intelligent network car.At the same time,the system also supports the traditional car bus such as CAN,FLEXRAY,LIN,Can be integrated with other vehicle control systems.(3)System has a variety of load balancing mechanism.High-performance computing node load balancing mechanism can intelligently calculate the performance of different nodes at Run-time to migration tasks between nodes to achieve the load balancing between nodes load balancing to prevent performance bottleneck.The task type migration mechanism can dynamically change the task type during deployment according to the service characteristics of the task so as to achieve load balancing among different types of platforms.
