Airflow Estimation Control Strategy Based on Speed Density Method

摘要

According to the analysis of speed density method and the principle of volume estimation, the intake airflow calculation control strategy can be designed with Simulink toolbox. The Embedded Coder toolbox can be used to automatically generate the code of above control strategy and then integrate the code into the ECU. Finally, the control algorithm is verified using bench test and real vehicle test, and the result shows that this estimation algorithm can accurately estimate intake volume, which means that we achieve the desired design requirements.
