摘要： The invention relates to a method for detecting malfunctioning in a sensor which detects a measured variable. A signal range check is carried out for the output signal of the sensor when the measured variable is situated within a permissible range. Said check is not carried out, however, the output signal is used for detecting the measured variable and for further calculation when the measured variable is situated outside said permissible range. The sensor is a hot film air mass sensor (HFM) in a motor for instance. In this case, the measured variable is the intake air mass and the signal range check is only carried out when the operating state of the motor and thus the intake air mass fulfil conditions that can be pre-determined. In addition to the signal range check, onboard diagnoses are carried out with regard to plausibility criteria. Said diagnoses relate to the offset drift and/or the sensitivity drift of the sensor.

摘要： The invention relates to a device for determining the flow rate of a flowing medium, for example, of the air flowing inside the induction pipe of an internal combustion engine. According to the invention, the output signal of a sensor element exposed to the flowing medium is converted into a digital signal that is conditioned and corrected inside an evaluation device that functions in an all-digital manner. The conditioned digital signal is transmitted via an interface to a control unit located downstream therefrom.

摘要： PROBLEM TO BE SOLVED: To adjust an air volume accurately by detecting at least one temperature and pressure by a sensor and calculating a first volume of supplied air based on the detection result, as well as detecting a second volume of supplied air by another sensor and utilizing it for controlling the air volume. SOLUTION: A sensor 125 is disposed in a new air piping 105 connected with an internal combustion engine 100, and signals TL and PL indicating a temperature and pressure of the new air respectively are input in an electronic control unit 140. During operation of the internal combustion engine 100, a compressor 130 is rotated by exhaust gas via a turbine 115 supplying the internal combustion engine 100 with the new air. During this time, the electronic control unit 140 receives a signal ML related to a intake air volume from an air mass meter 127 and calculates a first volume of supplied air based on the detection result of the temperature and pressure. Then the electronic control unit 140 corrects a second amount representing the air volume supplied by the air mass meter 127 based on the first volume. Then air volume control is performed based on the air volume after correction.

摘要： A gas sensor for determining the physical parameters of gases is disclosed, comprising a capacitor, the dielectric layer (3) of which is in contact with the gas, in such a way that a change in the physical properties thereof, leads to a corresponding change in the dielectric constant. A gel layer (4) is arranged on the gas sensor (1), in the vicinity of the dielectric (3). The sensor is embodied as a sensor for determining the moisture content of the gas. Foreign materials present in the passing gas stream are kept from the moisture sensitive layer itself (dielectric layer 3) on the capacitor, by means of the gel layer (4), whilst the water to be recorded in the humidity determination can easily reach this layer (4) by diffusion and diffuse out again.

摘要： Methods and/or devices for detecting the flow rate of a flowing medium, in particular the flow rate of a flowing air mass, are described, in which the flowing medium is detected with two evaluation methods that operate according to different principles and the two measurement signals obtained are set in relation to each other in order to determine correction methods. Since the two measurement methods react differently to interference effects, the comparison of the two output signals permits conclusions to be drawn as to the type and the order of magnitude of the interference effects and a corrected measurement signal can be obtained, which is independent of the interference effects.

摘要： A measuring device, with a digital interface for the transmission of digital signals to an analytical unit, is disclosed, whereby the interface comprises a clock input, to which a system clock signal is fed, a signal input, to which a measured signal is applied, a arithmetic unit, which derives an output signal from the clock signal and measured signal and a signal output where the output signal is supplied and transmitted to the analytical unit. According to the invention, the measurement accuracy may be improved, whereby a reference signal is transmitted, which is a signal derived from the clock signal and said reference signal is used for correction of the output signal.

摘要： 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.
