Method of estimating the fuel/air ratio in a cylinder of an internal-combustion engine by means of an extended Kalman filter |
摘要 |
The present invention relates to a method of estimating the fuel/air ratio in each cylinder of an injection internal-combustion engine comprising an exhaust circuit on which a detector measures the fuel/air ratio of the exhaust gas. An estimator based on a Kalman filter is coupled with a physical model representing the expulsion of the gases from the cylinders and their travel in the exhaust circuit to the detector. The method has application to engine controls.
