摘要:
A device for signal path control in a motor vehicle permits the reception or the transmission of signals from or to a multiplicity of electronic units via a cable with a small number of line conductors. The device is universally applicable and is suitable for both on-board and off-board applications. Its robustness makes it suitable also for diagnostic systems in motor vehicles.
摘要:
A method for detecting malfunctions in a motor vehicle, in which data words formed in subassemblies (sensors or components) upon detection of a malfunction therein are read by an analysis unit. The data words are also formed by the subassemblies when a malfunction detected by a peripheral subassembly is not traceable to said subassembly. Functional chains are determined in a device on the basis of the malfunctions detected by the subassemblies and represented by the corresponding data words. The functional chains contain all the sources of error related to the malfunctions. A list of test steps is drawn up in the device and stored at memory locations provided for this purpose. The test steps allow checking all the sources of error, and the functional chain is completely checked after execution of the test steps.
摘要:
A control device for controlling a system having a processor for executing control programs, memory means for storing data and control programs, and interface modules which can be used to transfer control instructions to actuators or to further control devices is connected to other control devices by means of a data bus. The control device includes a plurality of cells of the same type, each of which has a piece of reconfigurable hardware and peripheral modules. These cells can be reconfigured by configuration data, so that hardware connections for each cell can be adjusted to adapt to a desired control process. One or more cells together form a processor and/or interface modules.
