μC/OS-Ⅱ在混合动力汽车总控制中的应用

Research on Application of μC/OS—Ⅱ in HEV control System

混合动力汽车(HEV)控制系统一直是电动车的核心控制部分。论文介绍了其控制系统具有多任务、实时性的特点,开发了一套基于Freescale MC9S12DP256控制器与CAN总线设计的混合动力汽车管理系统,提出了在软件开发中引入嵌入式实时操作系统μC/OS—Ⅱ,并重点详述了μC/OS—Ⅱ在该系统中的移植与应用。经过理论和实验证明,该控制系统实时性强、可靠性高。

The vehicle control system is one of key parts in hybrid electronic vehicle.This paper introduces the features of control system that has muhitask and real time.This system based on Freescale MC9S12DP256 MCU and CAN bus is developed.The application of μC/OS--II to its embedded software design is put forward.And the transplant and application of μC/OS--II are particularly described in detail,The theory and experiment shows this control strategy to be a system of better real time and higher reliability.
