    摘要： A method and an apparatus for controlling an internal combustion engine are described. At least one sensor serves to detect a first variable that characterizes the pressure in the combustion chamber of at least one cylinder. A second variable, which characterizes the maximum value of the change and/or the location of the maximum value of the change, is determined on the basis of this first variable. This second variable serves to control operating parameters of the internal combustion engine in an open-loop and/or a closed-loop manner.

    摘要： A method for calibrating at least two sensors for sensing a variable characterizing the combustion process in an internal combustion engine of a motor vehicle, operated in individual-cylinder fashion and having at least two cylinders, is provided. According to the present invention, at least one operating point of the internal combustion engine, at which an equalization of the at least two cylinders by at least one fuel quantity equalization method is performable with high accuracy, is determined. At the at least one operating point of the internal combustion engine, an equalization of the at least two cylinders is performed by the at least one fuel quantity equalization method. After the equalization of the at least two cylinders has been accomplished, at least one sensor parameter of the at least two sensors is mutually adjusted.

    摘要： A method for correcting the position of the angle marks of an incremental gear of a rotary speed sensor and/or rotary angle sensor of an internal combustion engine and to a system therefor. The method is characterized by the following steps: a) recording the angle marks using the rotary speed sensor and/or the rotary angle sensor, b) measuring the combustion chamber pressure in the respective cylinder of the internal combustion engine, c) assigning a measured pressure value to the recorded angle mark positions, d) possibly correcting the measured pressure values in a signal-conditioning device, e) storing the recorded angle mark positions with the appertaining, measured pressure values in a measured value table, f) storing of the ideal pressure values derived at the ideal angle mark positions in a reference table, g) comparing the pressure values, that were measured and possibly preprocessed in the signal-conditioning device to the ideal pressure values, h) determining deviations of the measured angle mark positions from the ideal angle mark positions, at the corresponding cylinder pressure values in an evaluation unit, and i) correcting the measured angle mark positions by the deviations determined.

    摘要： A device and a method are described for controlling an internal combustion engine, in which a control deviation and a governor are allocated to each cylinder of the internal combustion engine, each governor preselecting a cylinder-specific triggering signal on the basis of the allocated control deviation. Cylinder-specific actual values are ascertained on the basis of a signal from a sensor arranged in the exhaust train and are compared to a setpoint value. Triggering signals for the cylinder-individual control of the fuel quantity and/or air quantity are preselected on the basis of the comparison.
