In order to avoid data inconsistency between accesses of different functions of an application to a global variable in a data processing system,

Data consistency in data processing systems

A method and a computer system for operating at least two interconnected control units. The control units access sensor data and each execute at least one computer program for controlling operational sequences, in particular in a vehicle. The control units exchange synchronization information with one another. In order to design and refine a computer system in a way that will enable even especially complex operational sequences, as required in a modern motor vehicle, for example, to be controlled and/or regulated simply and cost-effectively with the aid of the computer system, using conventional control units, the control units execute the same computer program time-synchronously using a settable time lag.

Method and computer system for operating at least two interconnected control units

A method for triggering an internal combustion engine of a certain type according to a state machine is provided, in which a possible operating state of the engine, which is assigned to a layer n of the state machine, is first set. In an additional layer (n+1), sub-states to the previously determined operating state are specified. For triggering different type engines, the method provides that the state machine has at least two groups of layers, the first group of layers representing operating states that the engine of the certain type has in common with engines of another type, and the second group of layers representing operating states that are specific to the engine of the certain type.
