A control device and a method for operating a control device which contains function modules, a scheduler and a priority manager. The control device is connected via data lines to a system to be controlled. The priority manager assigns to the modules modifiable priorities which are then taken into account when the modules are activated by the scheduler.

Control device for a system, and method for operating the control device

A control unit for a system and a method of operating a control unit have modules that are activated. Before activation of a certain module, inquiries are made to detect cross-dependencies with other modules that have already been activated. To do so, a first storage device and a second storage device containing this information are provided. A scheduler prevents modules which interfere with one another from being activated simultaneously.

System and method for a control unit with a scheduler preventing simultaneous activation of modules from interference

An internal combustion engine ( ), especially of a motor vehicle, is described. The engine ( ) is provided with a combustion chamber ( ) into which fuel can be injected in a first operating mode during a compression phase and in a second operating mode during an induction phase. The engine ( ) is provided with a control apparatus ( ) for switching over between the operating modes. The engine ( ) includes an exhaust-gas recirculation having an exhaust-gas recirculation valve ( ). The engine ( ) is switched by the control apparatus ( ) into the first operating mode when the exhaust-gas recirculation valve ( ) is jammed in the open state.

Method for operating an internal combustion engine

Method and arrangement for operating an internal combustion engine ( ) which is operable in several operating modes, especially an internal combustion engine ( ) having direct injection or intake manifold injection and having a control apparatus ( ). The control apparatus ( ), that is, its software has a plurality of functions ( ) and a scheduler ( ) for activating the functions ( ). The executability of the functions ( ) 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.

Method and arrangement for operating an internal combustion engine

Method and arrangement for operating an internal combustion engine ( ) which can be operated in several modes of operation, especially an internal combustion engine ( ) having direct injection (DE) or intake manifold injection (SRE) and with a control apparatus ( ). The control apparatus ( ) or its software has a plurality of functions ( ) and a scheduler ( ) for activating the functions ( ). Operating modes are assigned to the functions ( ) and the functions ( ) are activated by the scheduler ( ) in dependence upon the assigned modes of operation.

Method and device for operating an internal combustion engine

An internal combustion engine especially for a motor vehicle is described which is provided with a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover can be made between the operating modes in dependence upon a desired operating mode. The desired operating mode can be determined from a plurality of operating mode requests by the control apparatus.

The invention is directed to an internal combustion engine, especially for a motor vehicle. The engine has a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover between the operating modes can be effected. A desired value (rlmd$s) can be determined with the control apparatus for the air charge in the combustion chamber. The desired value (rlmd$s) defines a maximum value for the air charge in the combustion chamber which is not exceeded.

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.
