A control device and a corresponding control method are provided for establishing an information-output ranking of a plurality of information sources, in particular audio sources. In order to output the information of the information sources to a common information-output device, the information-output ranking is established in pairs for the audio sources which is in the form of an audio-output matrix having a nonlinear order with respect to the matrix elements, and wherein each matrix element of the information-output matrix is used to determine the priority of a corresponding information source with respect to another information source. A conflict among competing information outputs is solved in this manner.

Control device and control method for fixing an information output order for several information sources, especially audio sources

A circuit arrangement for reducing a variable, in particular pulsed input voltage (U,) to an operating voltage U,, U,to be delivered to an evaluation circuit (,), in which the input voltage U,can be reduced, in accordance with a division factor (F) made available by at least one voltage divider (R,, R,, T,, R,; R,, R,, R,), to obtain the operating voltage U,, U,, in which the at least one voltage divider (R,, R,, T,, R,; R,, R,, R,), can be regulated in such a way that the division factor (F) can be increased with an increasing input voltage U,and can be decreased with a decreasing input voltage U,.

Circuit for reducing input voltage

A method and apparatus for fault recognition in an internal combustion engine, such as an auto-ignition internal combustion engine. A defect in the metering system is recognized if the boost pressure deviates from an expected value.

Method and apparatus for fault recognition in an internal combustion engine

A system is provided for controlling a fuel-metering device, for a diesel engine. First means generate a first signal for triggering a first actuating means (115) for establishing the start of pump delivery and the end of delivery. Second means generate a second signal for triggering a second actuating means (125) for establishing the delivery rate. In this case, a signal characterizing the start of pump delivery is taken into consideration by the second means.

System for controlling a fuel-metering device

A method and a device for the open-loop and/or closed-loop control of a final controlling element, in particular for influencing the fuel injected into an internal combustion engine, are described. A system deviation is defined starting from a setpoint and an actual value. On the basis of the system deviation, a loop controller specifies a manipulated variable to be received by the final controlling element. If the system deviation lies outside of a range defined by at least two values, a maximum value is specified for the manipulated variable.

A device and a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, having at least one solenoid valve, are described. On the basis of a desired quantity of fuel, an actuation period is determined for the solenoid valve and a signal for fixing the end of actuation is prescribed on the basis of the actuation period. Depending on the operating state of the internal combustion engine, the actuation period is determined either by means of a pump characteristic table or the desired quantity of fuel is used directly as the actuation period. Moreover, depending on the operating state of the internal combustion engine, either an uncorrected or a corrected signal is used for fixing the end of actuation.
