    摘要: A procedure is introduced to test the functional capability of a secondary air system of an internal combustion engine, wherein values of a pressure are acquired, which arises in the secondary air system between the secondary air pump and a secondary air flow cross section, which can be controlled, when the secondary air pump is activated and the actuation of the secondary air flow cross section is increased; in that a measurement for the pressure is developed from the acquired values and is compared with a set point value, and the functional capability of the secondary air system is assessed as a function of a result of the comparison. The procedure characterizes itself in such a way, that in a secondary air system, whose secondary air flow cross section is controlled by two secondary air valves, wherein one of the two secondary air valves is actuated to close, while the other one of the two secondary air valves is actuated to open, and the assessment of the functional capability for a section of the secondary air system occurs in the section, in which the secondary air valve actuated to open is disposed. In addition a control unit is introduced, which controls the sequence of such a procedure.

    摘要: A method for diagnosing a secondary-air system of an internal combustion engine. The secondary-air system introduces secondary air into the exhaust-gas region of the internal combustion engine, the secondary air exothermically reacting together with combustible exhaust-gas components, and a thermoreactor being formed in the reaction region. The method provides for a measure of the secondary air to be ascertained from the thermal behavior in the thermoreactor and evaluated. The measure of the secondary air, which reflects, for example, the volumetric flow rate of the secondary air, the mass flow rate of the secondary air, or the amount or mass of secondary air flowing in a time interval, is compared to at least one threshold value. At least one diagnostic signal is then generated as a function of the comparison result.

    摘要: A method for error detection and error correction in the monitoring of measurement values is disclosed, in which the value to be tested is checked for plausibility in an evaluation device, for example a computer, and in the event that an implausibility is identified, the existence of an error is determined. If a further check finds that the error no longer exists, then an error correction takes place. A prerequisite for the error correction, however, is that the range of the value to be monitored in which the error has occurred is also the range in which a current error is no longer occurring. In an expanded method, a differentiation is also made between different errors and an error correction is only possible if it involves the same type of error.
