摘要： Method for controlling boost pressure in an internal combustion engine, using a boost pressure control device by means of which from the control deviation between a setpoint boost pressure and an actual boost pressure a manipulated variable is generated which has a D portion supplied by a differential control unit or a damper, the D portion being adapted as a function of a control deviation of a transient effect detected and evaluated for a predetermined evaluation time period, wherein the D portion adaptation includes an operating point-dependent D portion depth adaptation and/or an operating point-dependent D portion time adaptation, whereby the output variable for the differential controller is adapted by the D portion depth adaptation, and the operating time of the D portion corresponding to predetermined boost pressure parameters, in particular characteristic map parameters, is adapted by the D portion time adaptation.

摘要： A method for switching the modes of operation of an internal combustion engine switches between a method of homogeneous compression ignition and a conventional combustion method. The operating ranges of the modes of operation are defined at least by way of speed of rotation and load, and a switch between the operating ranges takes place as a function of the current operating point and of quantifiable characteristics of the trajectory as well as of the distance of the current operating point from the range limit of the operating range. Characteristics of the trajectory are the current movement direction and/or the speed of approach of the operating point to the range limit.

摘要： The invention relates to a method for controlling boost pressure in an internal combustion engine, using a boost pressure control device by means of which from the control deviation between a setpoint boost pressure and an actual boost pressure a manipulated variable is generated which has a D portion supplied by a differential control unit or a damper, the D portion being adapted as a function of a control deviation of a transient effect detected and evaluated for a predetermined evaluation time period. According to the invention, the D portion adaptation, performed in particular for adapting the boost pressure pulse duty factor for a boost pressure control valve, includes an operating point-dependent D portion depth adaptation and/or an operating point-dependent D portion time adaptation, whereby the output variable for the differential controller is adapted by means of the D portion depth adaptation, and the operating time of the D portion corresponding to predetermined boost pressure parameters is adapted by means of the D portion time adaptation.
