Abstract: A method for linearizing sensor signals in a magnetic strip length measuring system moves a sensor head between two magnetic poles of a measurement body. In particular, linearization takes place dynamically during operation of the magnetic strip length measuring system, and linearization deviations are compensated by extrapolation as the sensor head moves between the two poles of the measurement body from pole to pole or from pole pair to pole pair.

Abstract: An internal combustion engine has a crankcase and a crankcase ventilation system having a switchable shut-off valve, and sensors that detect different operating parameters of the engine, including a load variable of the engine. An estimated load parameter is determined based on the different detected operating parameters using a dynamic model, and a corrective value of a characteristic value is determined as a function of a deviation between the estimated load variable and the detected load variable. To implement a diagnosis, diagnosis switching cycle(s) are controlled, in which the shut-off valve is set to a closed switched position for a first time and set to an open switched position for a second time. A diagnosis value representative of a shut-off valve being in a correct or incorrect state is determined based on a change to the corrective value in response to the one or the plurality of diagnosis switching cycles.

Abstract: Encoded scale bodies for position/displacement measuring systems and position/displacement measurement systems including scale bodies are disclosed. An encoded scale body includes a support band and at least one encoding layer made of encoding material. The encoding layer is arranged on the support band. The encoded scale body further includes a cover band which covers the encoding material towards an outside space. The cover band is formed by the support band. The support band/cover band is elastically flexible. The support band, which is the mechanical holder for the encoding material, may serve to mechanically stabilize the encoded scale body. The cover band covers the encoding material and may protect the encoding layer from external effects such as, in particular, mechanical forces. The flexible support band/cover band may permit the encoded scale body to be used as band material, and for example, a roll material.

Abstract: An internal combustion engine has an intake tract having a compressor. A verification is performed as to whether at least one predefined activation condition is met. A boost pressure (PUT) downstream of the compressor is sensed or determined. An adaptation characteristic curve or adaptation characteristic map (KF_AD) is adapted as a function of a rotational speed (N) of the internal combustion engine and the boost pressure (PUT) if the at least one actuation condition is met. A gradient is determined that is representative of a gradient of the adaptation characteristic curve or adaptation map (KF_AD). From the determined gradient, conclusions are drawn with respect to a fault in the intake tract of the internal combustion engine.

Abstract: Actual values of a load variable are detected by a sensor during active model trimming under different valve pressure conditions, and a model of estimated values is created. Trimming values of a model parameter are determined depending on detected and modeled values such that when the model parameter is trimmed, the modeled values approximate the detected values. A function is determined depending on the different pressure conditions and approximated to the trimming values. At different pressure conditions first lambda control values are detected. A first controller value fitted function is determined depending on the pressure conditions and approximated. When the model trimming mode is not active, second lambda control values are detected at different pressure conditions. A second controller value fitted function is determined depending on the pressure conditions and is approximated. An error of the intake system is detected depending on the fitted functions.

Abstract: The precision of an intake manifold model for a supercharged internal combustion engine can be improved, wherein a first pressure value in the inlet tract (3) downstream of a throttle valve (6) and upstream of a compressor (7) and second pressure value (3) downstream of the compressor (7) are calculated by means of the intake manifold model. Furthermore, a first reference pressure and a second reference pressure are recorded by two pressure sensors (13, 14). It is determined whether the internal combustion engine (1) is operating in charging mode or not. The intake manifold model is then corrected on a difference between the first pressure value and the first reference value and a difference between the second pressure value and the second reference value depending on whether the operating mode is the charging mode or not.

An exhaust turbocharger of the internal combustion engine has a compressor (42) arranged in the intake system (1) and a turbine (48) arranged in the exhaust gas system (4) of the internal combustion engine for driving the compressor (42).

A leakage of the intake system (1) downstream of the compressor (42) is recognized if the determined charge pressure (PHS_AIC_DOWN) is lower than the predetermined base charge pressure (PUT_BAS) in the predetermined operating state.

Abstract: In an internal combustion engine, at a first operating point using no exhaust gas recirculation, a first measured value of a load variable is detected. As a function of a further operating variable, a first model value of the load variable is determined using a suction pipe model. At least one parameter of the suction pipe model is adapted such that the first model value approaches or corresponds to the first measured value. A first value of the parameter adjustment is stored. At a second operating point, using exhaust gas recirculation a second value corresponding to the first value of the parameter adjustment, is determined and stored. The first and second values of the parameter adjustment are compared and a parameter value of an exhaust gas recirculation model is adapted such that the first and the second values of the parameter adjustment approach each other or correspond to each other.
