摘要： A method for operating an internal combustion engine, in which at least one first influence variable influences a state variable of the air in the intake manifold. The state variable of the air in the intake manifold is ascertained while taking into account a plurality of influence variables, which influence the state variable, while using a first physical relationship. The same state variable is ascertained while taking into account a plurality of influence variables, which influence the state variable of the air in the intake manifold while using a second physical relationship. A specific adjusting parameter, which represents a specific error in the influence variable, is linked to each influence variable. The adjusting parameters are learned and monitored in the operation of the internal combustion engine. A certain adjusting parameter is learned and monitored in an operating range of the internal combustion engine in which the other adjusting parameters have a lesser influence on the state variable than that certain adjusting parameter, and in this context, the certain adjusting parameter is adjusted in such a way that the state variable ascertained by using the first physical relationship is at least approximately equal to the state variable ascertained by using the second physical relationship.

摘要： In a method and a device for checking the adjustment of a plurality of actuators driven by a common drive in different mass flow channels of an internal combustion engine, the actuators are adjusted between a first limit stop and a second limit stop in the particular mass flow channel. The actuators are brought by their common drive to the first limit stop. A first value of a variable that is characteristic of a position of the common drive of the actuators is determined when the first limit stop is reached. The actuators are brought by their common drive to the second limit stop. A second value of the variable that is characteristic of the position of the common drive of the actuators is ascertained upon reaching the second limit stop. A difference is determined between the first value and the second value. The difference is compared in terms of absolute value to at least one predefined threshold value. An error in the adjustment of the actuators in the various mass flow channels is recognized when the absolute value of the difference deviates unacceptably from at least one predefined threshold value.

The offset is computed using an output signal of a pressure sensor, including: transferring the air duct into a predetermined operating situation in which a predetermined pressure difference is considered to be applied to the differential pressure sensor, measuring a level of the output signal in the predetermined operating situation, and computing the offset based on the measured level of the output signal.

摘要： In a method and a device for operating an internal combustion engine, a first variable characterizing the air-mass flow to the internal combustion engine is determined, and a second variable characterizing the air-mass flow is determined. The second variable characterizing the air-mass flow is used to derive a third variable characterizing the air-mass flow, which is delayed in time with respect to the second variable characterizing the air-mass flow. A difference is formed between the second variable characterizing the air-mass flow and the third variable characterizing the air-mass flow. The first variable characterizing the air-mass flow is corrected by the difference.

摘要： A network device and a computer program element are introduced for controlling data packet flows in a network device by manipulating data packets according to an actual manipulation rate. Amongst data packets received by a network device such as a router, data packets are identified that are marked with a pattern according to a congestion notification scheme. A pattern rate of data packets comprising such a pattern is determined, and the actual manipulation rate is determined subject to the pattern rate.
