基于OSEKWorks開發(fā)平臺的高壓共軌噴油控制系統(tǒng)的研究

Abstract：This paper introduced the embedded real—time operation system into the study of high pressure common rail fuel inj ection system．Using the real—time multitask operation system OSEKWorks not only
effectively improved the efficiency of software development but also improved the quality and reliability of the
developed software．Using the proper partition of task and scheduling mechanism based on priority improved
the efficiency of CPU．insured the need of real-time capability of electronic control fuelinjection system and
improved the transient response of diesel engines．The experiment proved that introducing multitask realtime operation system into high—pressure common rail electronic control fuel injection system is the key tech_nic that can insure the system running accurately and reliably．

務操作系統(tǒng)OSEKWorks，不僅有效提高了軟件的開發(fā)效率，而且也提高了軟件的質量和可靠
性。通過合理的任務劃分和基于優(yōu)先級的搶占式調度方式，提高了CPU的利用率，確保了電
控噴油系統(tǒng)的實時性要求，有效提高了發(fā)動機的動態(tài)響應性能。實踐證明，在高壓共軌電控噴油系統(tǒng)引入多任務實時操作系統(tǒng)，是確保高壓共軌電控噴油系統(tǒng)精確、可靠運行的關鍵，是提高柴油機性能的一個行之有效的途徑。
