| 摘 要： | 发动机电控系统具有较多的传感器和执行器、运行工况变化频繁,因此,发动机电控程序具有实时多任务的特点。研究将μC/OS-Ⅱ实时内核应用于捷达轿车发动机两用燃料电控系统软件设计,利用它的任务调度机制、同步机制及中断管理,实现了发动机实时多任务的管理和控制。发动机可使用汽油或LPG为燃料,且在两种燃料之间切换平顺,燃用LPG燃料时车辆性能达到了与原汽油机接近的状态。

| Abstract: | The engine control system consists of many sensors and actuators,and the engine operating conditions vary continually,so the engine program has the characteristics of realtime and multi-task.In this paper μC/OS-Ⅱ kernel is applied in the electronic control program development for the Jetta bi-fuel engine electronic control system,and used to manage and control engine multitask by using its OS features such as task schedule mechanism,synchronization,interrupt management service,etc.The engine can run in either gasoline or LPG,and can swith from one to another smoothly,and the vehicle performance operating with LPG is very close to the one with gasoline. |

| Keywords: | engine control system μC/OS-Ⅱ embedded operating system real-time multitask program development |
