摘要： A method is disclosed for operating an actuator having a coil and a displaceably mounted armature driven by a magnetic field generated by the coil, in a measurement operating mode for ascertaining a time at which the armature reaches its stop position after activation of the actuator. The method includes applying to the coil an actuation voltage signal dimensioned such that the expected armature stop time falls in a time window in which a temporally constant voltage is applied to the coil, detecting an intensity profile of the current flowing through the coil within the time window, and determining the armature stop time, based on an evaluation of the detected current intensity profile. A method for operating such an actuator is also disclosed, wherein information about the stop time is obtained in a measurement operating mode and used in a series operating mode for optimized actuation of the actuator.

摘要： A first exhaust gas sensor signal (vls_up) of a first exhaust gas sensor (AS1) is detected. In addition, a second exhaust gas sensor signal (vls_down) of a second exhaust gas sensor (AS2) is detected. A relevant first estimated value of an emission of at least one exhaust gas component is determined in relation to a position of the first exhaust gas sensor (AS1) in the exhaust gas tract as a function of the first exhaust gas sensor signal (vls_up) and a relevant second estimated value of an emission of the at least one exhaust gas component is determined in relation to a position of the second exhaust gas sensor (AS2) in the exhaust gas tract as a function of the second exhaust gas sensor signal (vls_down). A conversion rate (K) of the at least one exhaust gas component is estimated as a function of a ratio of the second estimated value and the first estimated value of the determined emission. The exhaust gas catalytic converter is diagnosed as a function of the determined conversion rate (K).

摘要： A plateau phase of a test signal of an exhaust gas probe located in a catalytic converter is detected following a jump from a preset rich air/fuel ratio in a combustion chamber of one cylinder to a preset lean air/fuel ratio, the plateau phase being obtained following the jump, and the duration is determined as a storage period. A plateau phase of the test signal, which is obtained following a jump from a preset lean air/fuel ratio to a preset rich air/fuel ratio, is detected following the jump, and the duration of the plateau phase is determined as an evacuation period. An allocation rule for assigning the test signal to a detected air/fuel ratio is adjusted according to the storage period and the evacuation period. To calibrate the exhaust gas probe, the allocation rule is adapted according to a plateau value of the test signal during the plateau phase.

A second oxygen storage capacity value is determined as a function of the measurement signal of the exhaust gas probe and the predefined second rich air/fuel ration.

摘要： An internal combustion engine has at least one cylinder, with which an injection valve for metering fuel is associated and an exhaust system with an exhaust gas catalytic converter. A first exhaust gas probe is disposed upstream of or in the exhaust gas catalytic converter, and a second exhaust gas probe is downstream. A lambda controller determines a regulating variable as a function of the first probe and a control variable acting on a fuel mass to be metered using the injection valve. A trim regulator determines a regulating variable thereof as a function of the second probe and the first trim control variable thereof as a function of a P regulator component and the second trim control variable thereof as a function of an I regulator component. A function of a predetermined evaluation of the first trim control variable decides whether the second trim control variable is adapted.
