    摘要： The invention relates to a method for the control path modification of a lambda control system, which is connected on the input side to an exhaust gas probe, and wherein a dynamic behavior and/or dead time behavior that varies as a result of the probe construction, of a manufacturing tolerance, of a variable probe temperature, or of aging is taken into consideration and the control behavior of the lambda control system is adapted accordingly. According to the invention, it is provided here that by means of a purely software-based adaptation, the control behavior of the lambda control system is adapted to the design of different exhaust gas probes and the dynamic characteristic thereof. The invention further relates to a corresponding device for carrying out the method. Using the method and the device for carrying out the method, different commercially available exhaust gas probes can be operated with the same control apparatus hardware. The different dynamic characteristics of the exhaust gas probes are reproduced here using different adaptable feedbacks. This is particularly advantageous in terms of a standardized hardware platform in engine control apparatuses for combustion engines and thus with a view to the costs.

    摘要： The invention relates to a method for determining a measurement variable (Q), characterized by the following steps: providing a model (M) of a circuit (DAC) having at least one parameter (tau, Imax); actuating the circuit (DAC) by way of a preset signal (H), and detecting values (l1, l2,l3) of a manipulated variable (I) generated by the circuit in n discrete points in time (t1, t2, t3), and determining a value (tauDAC, lmaxDAC) of the at least one Parameter (tau, lmax) on the basis of the detected values (I1, l2, l3) of the manipulated variable (I) generated by the circuit (DAC); detecting values (J1, J2) of a variable (J) influenced by the circuit (DAC) in m discrete points in time (T1, T2), and determining the measurement variable (Q) from the measurement values (J1, J2) of the variable (J) influenced by the circuit (DAC), taking into account the model (M) of the circuit (DAC).

    摘要： The invention relates to a method for operating a heatable exhaust sensor (20), which provides at least one measurement signal (26) and in which a sensor heater (24) is operated by an impulse width modulated operating voltage (28), and to devices for carrying out the method. The procedure according to the invention is characterized in that detecting the at least one measurement signal (26) has precedence over the providing of the impulse width modulated operating voltage (28) for the sensor heater (24) and that, at least during a specified measurement window (30, 32) in which the measurement signal (26) is detected, the providing of the impulse width modulated operating voltage (28) for the sensor heater (24) is suppressed by a blocking signal (18).
