摘要：

基于MotoTron控制器快速开发平台，开发了面向实际应用的汽油发动机快速原型控制器.在MotoTron平台的开发软件MotoHawk中建立了控制器系统框架，配置了底层软件，并定义了系统的输入输出信号；在Matlab/Simulink中，开发了汽油机控制策略，包括电子节气门控制、空气量控制、喷油控制、点火控制和附件控制等；在台架上进行了发动机起动测试，验证了发动机控制各功能模块.试验结果表明，发动机起动迅速、可靠，工况转换平稳，各工况的空燃比可控，实现了发动机控制器的基本功能.

Abstract:

The popular V-model development process, which is characterized by high efficiency and excellent performance, has been widely applied in controller development process. The rapid prototyping acts as a part of the V-model process. The control strategy can be realized and validated conveniently. The cost and development risk can be reduced simultaneously. In this paper, a gasoline engine controller was developed based on MotoTron rapid prototyping platform. First, the control system frame was established under MotoHawk toolkit and the basic software and system I/Os were configured. Then the engine control strategy was developed with Matlab/Simulink, including electronic throttle control, air control, fuel injection control, ignition control and accessory control. Finally, an engine start test was conducted on bench to validate the engine control functions. The test results show that the engine starts quickly and reliably. The engine state transitions are smooth. The air-fuel ratio of each engine start stage is well controlled. The fundamental functions of gasoline engine controller have been realized.
