摘要： The invention relates to a method for controlling an internal combustion engine (10) comprising an accelerator pedal (48) which is mechanically coupled to the throttle valve (16), the position of said accelerator pedal being detected by means of a sensor (59) and transmitted to the motor control system (46). In the event of the sensor (50) being faulty, the motor control system switches to a first control mode or to a second control mode. In the first control mode, a defectuous actuation of the accelerator pedal (48) is presumed. In the second control mode, the valve (20) situated in the bypass (18) is controlled according to at least one parameter of the motor control system (46) which is not directly dependent on the air mass.

摘要： The invention relates to a method for regulating an internal combustion engine according to one or several physical models, wherein measurement values and adjustment values are provided as system parameters, underlying the physical model, in order to operate the internal combustion engine according to a regulation. One or several adaptation values can be applied, respectively, to said system parameters, in order to adapt said physical model to real conditions of the internal combustion engine. Estimation parameters are determined by means of said system parameters. Measurement parameters are determined on a measurement of the physical parameters, underlying estimation parameters. Said measurement parameters are evaluated in relation to the estimation parameters. Adaptation values are determined for at least one part of said system parameters according to an adaptation method, by means of said measurement parameters, and a first operation mode or a second operation mode is adopted depending on said adaptation values.

摘要： An internal combustion engine has at least one actuator which influences the gas exchange in the corresponding cylinder. The position of the first actuator(s) is varied and in given controlled positions, measured parameters for determining a first and further estimated parameters are recorded, whereby the first and/or further estimated parameters are determined from an estimated value or a measured value for the position of the first actuator(s) and a correction value for the estimated value or the measured value for the position determined. An optimisation procedure is carried out by means of which deviations of the first estimated parameter from the further estimated parameters for all given controlled positions are minimised by a matching of the correction value for the estimated value or measured value for the position. In the wider operation of the internal combustion engine, at least one set parameter is determined for control of the first actuator(s) and/or the further actuators dependent on at least one estimated parameter, which is dependent on an estimated value or a measured value for the position of the first actuator(s) and is also dependent on the correction value of the estimated value or measured value for the position.

摘要： An internal combustion engine has a plurality of cylinders (Z1 to Z4) having combustion chambers and each being associated with a spark plug (35) designed for igniting a mixture of air and fuel in the combustion chamber, and at least two adjusting devices for adjusting the air supply to the combustion chambers of the different cylinders (Z1 to Z4). To control the internal combustion engine, an individual ignition angle is detected for each group of cylinders (Z1 to Z4) to which the same air mass per working cycle is respectively supplied and during the respective working cycles of which the same loss torque is decisive. The decisive loss torque is the one associated with the cylinder that is in its intake cycle during the respective working cycle of the respective cylinder of the respective group. The individual ignition angle for each group is detected as a function of the decisive loss torque for the respective group.

摘要： The invention relates to an internal combustion engine comprising a camshaft that acts on gas exchange valves, and a phase displacement device by which means a phase (PH) between the camshaft and a crankshaft can be displaced. Said internal combustion engine also comprises an exhaust gas probe which is used to detect a variable characterising an air/fuel ratio in the cylinder, at least one sensor for detecting the phase (PH), and at least one regulating element which acts on the internal combustion engine. Measuring data records (MDS) associated with the different detected phases (PH) are determined, and comprise, in addition to the detected phase (PH), at least the detected variable characterising the air/fuel ratio in the cylinder. An optimisation method (OPT) is carried out, enabling a correction value to be determined for the detected phase (PH) according to the measuring data records (MDS), such that a quality function (GF) that depends on the variables associated with the measuring data records (MDS) is minimised or maximised. During the subsequent operation of the internal combustion engine, at least one regulating variable for controlling a regulating element is determined according to a detected phase (PH) corrected by means of at least one correction value (dPH). A defect in the internal combustion engine is diagnosed according to the correction value (dPH) for the detected phase (PH).
