    Abstract: A protection system for a pressure-charged (supercharged) combustion engine. In normal operation, the pressure-charging is controlled and/or regulated to a specifiable desired setpoint value P Setpoint. For the case of over-boosting of the internal combustion engine, various protective measures are provided, which are used in dependence upon the extent of over-boosting. In the case of a first protective measure, the control and/or regulation of the pressure-charging is switched off, and a final controlling element, which influences the pressure-charging, is adjusted to a predeterminable position. In the case of a second protective measure, the fuel metering to individual cylinders is interrupted in accordance with a predetermined skip pattern. If it is not possible to achieve an adequate reduction in the pressure-charging by this means, the system switches successively to further skip patterns with a higher skip frequency.

    Abstract: A method for determining the ignition point in ignition systems for internal combustion engines, having integrated knock control, a basic ignition point being determined on the basis of measured operating parameters using a stored characteristic map. The knock control, after engine knock has occurred, determines a knock control ignition point, which is more retarded than the basic ignition point, the knock control ignition point, in response to knock-free combustions, being altered step-by-step so as to be more advanced. Furthermore, a torque interface is integrated, which on the basis of the operating parameters and/or the demands placed by the driver, determines a torque-optimized ignition point, and the knock control ignition point being the most advanced permissible ignition point which is issued by the control unit.

    Abstract: A system for automatically controlling the supercharging of an internal combustion engine by controlling a variable parameter signal, such as pressure, air quantity, or air mass which characterizes the status of the internal combustion engine supercharging operation. The system includes a closed-loop control system. To optimize supercharging performance the response characteristic of the control system is determined as a function of the rotational frequency of the internal combustion engine and an operating parameter signal which characterizes the dynamic output response of the internal combustion engine and of the supercharger. In the case of large system deviations, the operating parameter signal is derived from the actual measured value of the control variable. The control system raises the value of the operating parameter signal when the control system is deactivated to avoid making an incorrect determination of the value of the operating parameter signal when the control system is then immediately reactivated. When small system deviations occur, the control system operates based on the assumption that the engine and supercharger are operating at a steady-state condition. Under such conditions, the control system uses a stored value for the value of the operating parameter signal.
