摘要： In order to control an internal combustion engine according to the invention, a polytropic exponent is determined in accordance with at least two measured values of the pressure in the combustion chamber of the cylinder, said measured values being detected after closing the gas discharge valve and before successively opening the gas intake valve. An exhaust gas mass which is located in the cylinder after closing the gas discharge valve and before successively opening the gas intake valve is determined according to the polytropic exponent at an estimated value of the pressure after closing the gas discharge valve and before successively opening the gas intake valve as well as at a certain temperature of the exhaust gas located in the cylinder after closing the gas discharge valve and before successively opening the gas intake valve. An actuation signal for controlling an actuating member of the internal combustion engine is generated in accordance with the determined exhaust gas mass.

摘要： In a device for controlling the internal combustion engine/drive train of a motor vehicle, based on process control variables of a combustion process that are distributed among a plurality of subsystems, an optimization unit stores information for carrying out the combustion process. The optimization unit determines the process control variables of the combustion process as a function of detected state and system variables and of at least one predefined value of a drive unit, and outputs them to the plurality of subsystems via corresponding, defined interface units. Distribution of the combustion process among the plurality of subsystems is carried out as a function of logical and physical requirements.
