混合動(dòng)力汽車（HEV）控制系統(tǒng)一直是電動(dòng)車的核心控制部分。論文介紹了其控制系統(tǒng)具有多任務(wù)、實(shí)時(shí)性的特點(diǎn)，開(kāi)發(fā)了一套基于FreescaleMC9S12DP256 控制器與CAN 總線設(shè)計(jì)的混合動(dòng)力汽車管理系統(tǒng)，提出了在軟件開(kāi)發(fā)中引入嵌入式實(shí)時(shí)操作系統(tǒng)μC／OS—II，并重點(diǎn)詳述了μC／OS—II 在該系統(tǒng)中的移植與應(yīng)用。經(jīng)過(guò)理論和實(shí)驗(yàn)證明，該控制系統(tǒng)實(shí)時(shí)性強(qiáng)、可靠性高。

Abstract: The vehicle control system is one of key parts in hybrid electronic vehicle ． This paper introduces the features of control system that has multitask 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 μ C ／ 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
Keyword: hybrid electric vehicle；μC／OS—II; real time operating system; control system
