摘要： The invention relates to a method and device for diagnosing deviations in a single cylinder lambda control in an internal combustion engine having at least two cylinders and an exhaust gas sensor designed as a broadband lambda sensor, wherein a pump current is evaluated by means of a pump cell and the pump current is used at least temporarily for an individual cylinder lambda control. According to the invention, a pump voltage or a pump voltage change is determined via the pump cell in addition to the pump current and the value is transmitted to a diagnosis apparatus. Deviations in the single cylinder lambda control can thus be better diagnosed without additional material expense according to the invention, which provides advantages in particular in respect of tightened rulemaking in on-board diagnosis. A preferred application of the method is the use in internal combustion engines having multi-bank exhaust systems.

摘要： A method for diagnosing an electrical lead to an electrode of a sensor element, for sensing at least one property of a measured gas in a measured gas space, in particular for sensing a proportion of a gas component in the measured gas or a temperature of the measured gas, is described. A measured signal indicating an internal resistance of a pump cell of the sensor element is investigated for regularity upon switching on of the control unit. Upon identification of at least one irregularity of the measured signal, a suspected fault in the lead is identified and at least one substitute action is taken. The substitute action is selected from: an application of control to the heating element which is provided for a fault situation, a check of the validity of the measured signal, and a monitoring of the heating element. A sensor apparatus is also described.

摘要： A method/device for evaluating oxygen sensor signals of an air supply channel connected to an exhaust gas channel of the internal combustion engine, via an exhaust gas recirculation having at least one exhaust gas recirculation valve; the oxygen sensor being downstream from the exhaust gas recirculation initiation; the sensor signal(s) being corrected as a function of at least one characteristics variable describing the dependence of the sensor signal on the oxygen concentration or a correlated variable, and/or additional physical variables. At at least one engine operating point(s), in response to a closed exhaust gas recirculation valve, output oxygen sensor signals and additional operating point parameters are recorded/stored; and an adaptation of the characteristic variables is derived assuming that the gas composition corresponds to pure air. Also, a characteristics curve adjustment and a compensation of pressure temperature dependencies may be performed to improve the accuracy of the oxygen sensor signals.
