  • Patent number: 7536241
    Abstract: 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.

  • Patent number: 7257813
    Abstract: 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.

  • Patent number: 6722350
    Abstract: An internal combustion engine (1), especially of a motor vehicle, is described. The engine (1) is provided with a combustion chamber (4) 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 (1) is provided with a control apparatus (18) for switching over between the operating modes. The engine (1) includes an exhaust-gas recirculation having an exhaust-gas recirculation valve (14). The engine (1) is switched by the control apparatus (18) into the first operating mode when the exhaust-gas recirculation valve (14) is jammed in the open state.

  • Patent number: 6637412
    Abstract: 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.

  • Patent number: 6539915
    Abstract: Method and arrangement for operating an internal combustion engine (10) which can be operated in several modes of operation, especially an internal combustion engine (10) having direct injection (DE) or intake manifold injection (SRE) and with a control apparatus (11). The control apparatus (11) or its software has a plurality of functions (12) and a scheduler (13) for activating the functions (12). Operating modes are assigned to the functions (12) and the functions (12) are activated by the scheduler (13) in dependence upon the assigned modes of operation.

  • Patent number: 6394063
    Abstract: 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.

  • Patent number: 6386174
    Abstract: 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.

  • Patent number: 6195763
    Abstract: 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.
