    摘要: A fault diagnostic device for monitoring and detecting faults in technical functions, in particular in technical functions of a motor vehicle, includes a plurality of monitoring devices for monitoring technical functions, whether they have a fault or not. The fault diagnostic device also includes a storage device for storing (data concerning) direct mutual dependencies of the functions to be monitored, in the form of a matrix representation in the logical YES/NO form. Furthermore, the fault diagnostic device includes a processing device for determining the capacity for validation of faults in corresponding technical functions to be detected in the monitoring, in view of the matrix representation; for controlling the monitoring devices for carrying out the monitoring activities; and, assuming the capacity for validation, for validating the faults to be detected in the monitoring.

    摘要: Method and arrangement for operating an internal combustion engine (10) which is operable in several operating modes, especially an internal combustion engine (10) having direct injection or intake manifold injection and having a control apparatus (11). The control apparatus (11), that is, its software has a plurality of functions (12) and a scheduler (13) for activating the functions (12). The executability of the functions (12) is determined in dependence upon the operating-mode dependent and operating-mode independent conditions and, with the aid of a bridging signal, the determination of the operating-mode dependent conditions can be disabled.
