Abstract: A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.

Abstract: A method and a device for controlling an internal combustion engine. A temperature variable and a pressure variable are detected by sensors. On the basis of at least the temperature variable and the pressure variable, a first quantity is determined that characterizes the air quantity, which is supplied to the internal combustion engine. A further sensor detects a second quantity that characterizes the air quantity, which is supplied to the internal combustion engine. The second quantity is adapted by the first quantity. Furthermore, the first quantity is used as a substitute value for the second quantity.

Abstract: A measuring device, with a digital interface for the transmission of digital signals to an evaluation unit, is disclosed, whereby the interface includes a clock input, to which a system clock signal is fed, a signal input, to which a measured signal is applied, an arithmetic unit, which derives an output signal from the clock signal and measured signal, and a signal output where the output signal is output and transmitted to the evaluation unit. Measurement accuracy may be improved by transmitting a reference signal that is a signal derived from the clock signal, and using this reference signal to correct the output signal.

Abstract: A method for detecting a malfunction of a sensor measuring a measured quantity is provided, in which a signal-range check for the output signal of the sensor is performed, provided that the measured quantity is within a permissible range. If the measured quantity is outside the permissible range, no signal-range check is performed, but the output signal is used for detecting the measured quantity and for further calculations. The sensor may be, for example, a hot-film air-mass meter. If this is the case, the measured quantity is the drawn-in air mass, and the signal-range check is performed, provided that the engine operating state and thus the drawn-in air satisfies specifiable conditions. In addition to the signal-range check, onboard diagnoses with regard to specifiable plausibility criteria relating to the offset-drift and/or the sensitivity-drift of the sensor may also be performed.

Abstract: In devices for measuring the mass of aspirated air of an internal combustion engine, for instance, via a line, it is already known to provide a tubular body inside this line and to provide a temperature-dependent measuring element inside the tubular body. In order that dirt particles and liquid droplets entrained by the aspirated air will be kept away from the measuring element, in accordance with the invention, a protective screen is disposed inside the tubular body, upstream of the measuring element; the screen extends in inclined fashion in the flow direction, and dirt particles and liquid droplets are deposited on it and carried to a downstream end of the protective screen, so that via an outflow opening they can reach the inner conduit wall of the tubular body and be made to bypass the measuring element.

Abstract: The invention relates to a device having a sensor carrier, which comprises a sheet-metal element and a plastic element and on which a measuring element introduced into the flowing medium is disposed. The use of plastic, which for the most part covers the sheet-metal element, means closer tolerances, which improve the performance of the sensor carrier both in terms of its facing into the flow and experiencing a flow around it, for instance by providing it with an improved aerodynamic leading edge, or the measuring element can be mounted flush to the surface and flush with edges of a sensor cavern, so that no turbulence occurs in the medium in the region of the measuring element or flow under the measuring element. The sensor region of the measuring element is reliably protected by recesses in the longitudinal edges and by a special adhesive bonding process from a gel emerging from the electronic evaluation circuit, so that the measuring characteristic curve behavior is not altered.

Abstract: The arrangement relates to a hot-film mass flow meter for recording the flow rate of a flowing medium in the intake tract or the charge air tract of an internal combustion engine. A substrate part is provided, that accommodates a sensor chip, which is allocated to a channel that has flowing through it at least one partial mass flow of the flowing medium. The sensor chip extends into channel that has flowing through it the partial mass flow of the flowing medium. The substrate part is formed either as a separately extruded plastic tongue or as a cavity extruded of plastic material. The sensor chip is integrated downstream with respect to a flow direction of the flowing medium, so as to lie behind a leading edge.
