Abstract: A virtual control unit according to the AUTOSAR standard, including a service layer, an ECU abstraction layer, and a microcontroller abstraction layer. It is provided according to invention that the virtual control unit additionally comprises a hardware layer that is configured to simulate at least one hardware component. A virtual control unit is provided in this way which enables easy use of environment models for HIL tests and software testing and a fast simulation.

Abstract: According to the invention, the operating software 10 of a technical system, particularly of a controller for controlling or regulating at least one technical device, is modified by virtue of hardware-dependent software components in the operating software 10 executable directly on the technical system not being executed and instead the functional behavior of the hardware-dependent software components being recreated by substitute functions 23. To this end, the hardware-dependent software components are automatically identified (step S1), and the substitute functions 23 are automatically ascertained or produced. On execution in a suitable simulation environment 200 (step S3), the operating software 20 modified in this way simulates the technical system independently of the real hardware 100 thereof.

Abstract: A method for manipulating the bus communication of an electronic control device is provided, wherein the bus communication includes a bus hardware-independent first communication layer and a bus hardware-dependent second communication layer. The first communication layer encodes at least one piece of information in a first protocol data unit and transmits it to the second communication layer and/or the first communication layer receives the first protocol data unit from the second communication layer and decodes the first information from the first protocol data unit. The second communication layer generates bus hardware-dependent bus information from the first protocol data unit or from an additional protocol data unit derived from the first protocol data unit for transmission via the bus and/or the second communication layer generates the first protocol data unit or an additional protocol data unit, from which the first protocol data unit can be derived.

Abstract: A computer project management system and method for the creation of an electronic control unit software is provided. The system has a software architecture tool configured to design a graphical model of an electronic control unit for a motor vehicle. A behavior model tool converts the graphical model into a computer readable production code. A software container has a file generated based on the electronic control unit. A container manager compares the software container with a prior software container during the importation or exportation of the software container to or from the software architecture tool or the behavior model tool, and a comparison list is generated indicating whether interface modifications for the electronic control unit were made. The comparison list is then displayed to a user on a display screen.

Abstract: A method for manipulating a memory operation of a control unit program on a memory of a virtual or real electronic control unit (ECU), such as is used in vehicles, for example. The manipulation of the memory operation is accomplished by a memory manipulation program component, via which a set of manipulation functions is provided, from which at least one manipulation function is selected, so that this function, by activating the memory manipulation program component, changes a memory access initiated by the control unit program in accordance with the selected manipulation function during execution of the control unit program.

Abstract: A modeling system and process for computer-aided, block-based modeling by preparing a first block diagram in a first model plane that relates to a first abstraction stage, in which at least one block is placeable in the first model plane and several blocks are connectable to one another by horizontal data transfer devices for horizontally exchanging data. At least one other block diagram is arrangeable on at least one other model plane assigned to the first abstraction stage that is separated from the first model plane. The first block diagram of the first model plane and the other block diagram of the other model plane form an overall block diagram that can be arranged on a selection of at least two model planes from the first model plane and the other model planes, so that a vertical exchange of data between at least two selected model planes can be produced.
