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.

Method for manipulating the bus communication of a control device

A test device for testing at least a portion of a virtual control unit with a simulation environment in a simulator, having the virtual control unit and the simulation environment. The virtual control unit has at least one software component with an external data interface. The simulation environment has a data interface for indirect data exchange with the virtual electronic control unit. A reduced dependency between the virtual control unit and the simulation environment with the result that electrical fault simulation with virtual electronic control units is possible in a simpler way, is achieved in that a virtual control unit pin module and a virtual manipulation unit are additionally provided between the virtual control unit and the simulation environment, the two units transmit a virtual physical control unit signal through a virtual control unit pin of the virtual electronic control unit pin module. The virtual manipulation unit outputs a manipulated virtual physical control unit signal.

Test device for testing a virtual electronic control unit

A test device for testing at least a portion of a virtual electronic control unit with a simulation environment in a simulator, having the virtual electronic control unit and the simulation environment. The virtual electronic control unit has a software component with an external data interface. The simulation environment has a data interface for direct data exchange with the virtual electronic control unit. A test device with reduced adaptation effort is implemented via a virtual electronic control unit pin module that has at least one virtual electronic control unit interface and is connected via the virtual electronic control unit interface to the external data interface of the software component of the virtual electronic control unit.

A method for automatic connection of model components of a model of a technical system on a computer with a display, wherein the model has a first model component and a second model component. The first model component and the second model component each have at least one hierarchy element, wherein a hierarchy element contains no hierarchy element, or one hierarchy element, or multiple hierarchy elements. A hierarchy element has no port, or one port, or multiple ports, wherein a hierarchy element and a port have an identifier. A connection between two ports represents an assignment in the technical system. A first set of hierarchy elements and/or ports and a second set of hierarchy elements and/or ports is selected through a graphical user action, wherein a possible assignment is tested for a first port of the first set and a second port of the second set. A possible assignment is present if, for the first port and the second port, and ascending from the first port and the second port in accordance with the hierarchy, the identifiers of the hierarchy elements that are at a higher level than the first port and the second port each correspond at equal hierarchy levels up to a predefinable number of hierarchy levels starting from the port, or are evaluated as corresponding in accordance with a predefined rule. If a possible assignment is present, the possible assignment is displayed and/or the first port of the first set is automatically connected to the second port of the second set.

Method for automatic display of possible connections and automatic connection of model components of a model of a technical system

An adjustment device for adjusting at least one control device with at least one control device microcontroller and with at least one control device debug interface, where the adjustment device comprises at least one programmable unit, at least one data transmission interface for connecting the adjustment device to an operating unit, and at least one adjustment device debug interface for connecting the adjustment device to the control device debug interface of the control device. The adjustment device according to the invention accomplishes the objective of reducing the load on the control device due to control device application by at least one address list and at least one data list, which are provided in a memory of the adjustment device.
