    摘要： In a method for determining a dead time in the response characteristic of an exhaust gas sensor in order to determine an exhaust gas state quantity in an exhaust gas duct of an internal combustion engine, the dead time is determined from a measured output signal of the exhaust gas sensor and a comparison signal. An undelayed comparison signal is determined, and a cross-correlation is formed between the measured output signal and the comparison signal delayed by a model dead time selected in such a way that the cross-correlation function assumes a maximum, and the dead time of the measured output signal is set equal to the selected model dead time.

    摘要： A method and a device for monitoring gas sensors in an internal combustion engine, in which in a steady-state operation of the internal combustion engine, the output signal of the gas sensor is filtered by a high-pass filter and higher-frequency signal components are analyzed by a comparison with an appropriately processed model value. When using the method and the device for executing the method, electrically oscillating gas sensors or the incoupling of interference variables or faults in the evaluation circuit, especially in the case of exhaust gas sensors in an exhaust-gas purification and reducing system, are able to be detected, which minimizes faulty interpretations in a dynamic diagnosis. This monitoring function is advantageously combinable with dynamic diagnosis functions that likewise analyze higher-frequency signal components by a comparison with appropriately processed model values. This increases the operational reliability of the exhaust-gas purification or reducing system.

    摘要： A method and a device for the dynamic monitoring of an air charging system of an internal combustion engine, subsystems of the air charging system having a low-pass characteristic, and a characteristic state quantity that is to be measured being compared with a modeled, identical state quantity. The measured signal and the modeled signal are filtered using a high-pass filter or bandpass filter, and, given a change in the characteristic state quantity that is to be measured, higher-frequency signal portions are evaluated, which is advantageous with regard to the recognition of so-called slow response errors.

    摘要： In a method for determining the lambda value with a broadband lambda sensor of an internal combustion engine, a measurement current is supplied by the lambda sensor, which measurement current is proportional to the oxygen content or rich gas content in the exhaust gas of the internal combustion engine, and the corresponding proportionality factor is determined by a thrust comparison. The thrust comparison uses the O2 concentration of dry air as reference, independent of an actually present air humidity, and the lambda value is calculated on the basis of a modified Pischinger conversion equation in which a signal supplied by a humidity sensor is taken into account.
