METHOD AND CONTROLLER FOR DETERMINING THE QUANTITY OF FILLING COMPONENTS IN A CYLINDER OF AN INTERNAL COMBUSTION ENGINE

The invention relates to a method for determining the quantity of filling components in a cylinder (1) of an internal combustion engine. The cylinder (1) is connected to an air supply (13) via an inlet valve (12) and to an exhaust gas conduit (15) via an outlet valve (14). The method has the steps of obtaining (31) an exhaust gas back pressure at a specified point in time when the outlet valve (14) is opened during a work cycle of the internal combustion engine and calculating (32) the quantity of the filling components at the specified point in time on the basis of the obtained exhaust gas back pressure. The invention further relates to a controller for carrying out the method and to a motor vehicle comprising such a controller. 本发明涉及种用于确定在内燃发动机的气缸(1)中的充填成分的量的方法，其中气缸(1)通过进气阀门(12)与空气供应装置(13)连接且通过排气阀门(14)与排气引导装置(15)连接。方法包括在内燃发动机的工作循环期间在预设的时间点时获得(31)排气背压，在该预设的时间点时排气阀门(14)是开启的，且基于获得的排气背压计算(32)在预设的时间点处的充填成分的量。此外本发明涉及种用于实施所述方法的控制装置和带有这样的控制装置的机动车。
