摘要
以嵌入式实时操作系统RX850作为软件开发平台,不仅可以充分利用硬件资源,同时也满足电控系统所要求的实时性和可靠性。根据高压共轨柴油机的实际工作状况,将整个系统划分为转速计算、喷油量计算、喷油正时计算等11个不同任务,有效地提高了系统运行效率和性能。
The software platform was based on the embedded RTOS of RX850. The hardware resources have been fully utilized, at the mean time, the requirement of real-time performance and reliability of electronic controlled unit has been met. According to the actual work of high pressure common rail diesel engine, the whole svstem is divided into 11 different tasks including speed calculated, injection fuel quantity calculated, injection time calculated and so on. Operating efficiency and performance of the system have been effectively improved.
