Study of The Task Scheduler Used In Automotive Electronics Software System

摘要

The Automotive Electronics technology is developing towards intelligent, microminiaturization, the inbuilt CPU as well as operating system in embedded system make the compositive control is feasible and applied widely. This paper firstly introduces the task scheduling mechanism of the real-time operating system, and analyzes the traditional PRI looking algorithm and its existing problems. Then proposes an improved table checking method based on the characteristics of Automotive Electronics. The new method will not only advance the determinacy and stability of the running time control, but also raise the fast execution ability of the software, the more accurate controls of the electronic working state of the car will be realized.
