Abstract: Systems and methods for simulating gas flow dynamics of a real hydrogen fuel cell system using a computer, wherein the real hydrogen fuel cell system includes a gas container volume network having gas container volumes interconnected by gas transport lines. The method includes defining volume element and flow channel classes, defining a plurality of volume instances and a plurality of flow channel instances, for each flow channel instance, creating a first interconnection representation that defines a source container volume and a destination container volume for the flow channel instance, wherein the first interconnection representation mimics a portion of the gas container volume network of the real hydrogen fuel cell system, and simulating, using the first interconnection representation, a thermodynamic state for each of the volume instances, the thermodynamic state representing thermodynamic parameter(s) in each container volume of the gas container volume network of the real hydrogen fuel cell system.

Abstract: A signal delay device includes a demultiplexer, D∈ delay means, D additional delay means, a multiplexer, and a control unit. For each delay means, a delay input and a demultiplexer output are connected, and a delay output and a multiplexer input are connected. For each additional delay means, an additional delay input is connected to a delay signal path, and an additional delay output and a multiplexer input are connected. The demultiplexer divides an input data word stream into parallel data word streams. Each delay means will delay the data words in the parallel data word streams. Each additional delay means will delay the data words in the delayed parallel data word stream by an additional delay time. The control unit controls the multiplexer such that an output data word stream corresponding to the input data word stream with a time delay is output.

Abstract: A method for simulating different traffic situations for an autonomous or semiautonomous test vehicle. The method includes the simulated driving of the test vehicle through a simulated road network, and the simulated randomized driving of other vehicles through the simulated road network. The method also includes the capture of vehicle driving parameters. Further according to the method, there is a determination of whether a predefined traffic situation is satisfied by the test vehicle and at least one of the other vehicles, the at least one other vehicle being within a test zone around the test vehicle. Where the predefined traffic situation is satisfied, randomized driving of the at least one other vehicle can be stopped, and the at least one other vehicle can be made to perform a predetermined driving maneuver. The predetermined driving maneuver can provoke a reaction by the test vehicle.

Abstract: A computer-implemented method for merging architecture data that are exchanged between an architecture definition tool and a behavior modeling tool includes: opening a first file with first architecture data and a second file with second architecture data in a comparison tool; comparing the first architecture data with the second architecture data to obtain a first list of differences; retrieving at least one combination rule, wherein the at least one combination rule comprises an identification rule for identifying a difference and a change to be applied to the identified difference; ascertaining a second list of differences that fulfill the identification rule and removing the differences of the second list from the first list; and applying the change defined in the at least one combination rule to each difference in the second list.

Abstract: A method for monitoring message packets that are exchanged between at least two control units. The message packets are concatenated in a data stream and each have an identifier, a payload, and a length specification of the payload described by a data item of predefined word size. The at least two control units are connected by a distributor. The distributor is connected by a first distributor port to a first of the at least two control units, is connected by a second distributor port to a second of the at least two control units, and is connected by a third distributor port to a computer system. The data stream flows through the first and distributor port for communication between the first node and the second node. The computer system has a memory, and information on the respective identifiers of the message packets is stored in the memory.

Abstract: Source code is generated from one or a plurality of blocks of a block diagram. The block diagram is hierarchical and includes at least a first subsystem that is configured for an incremental code generation. The block diagram references a definition database which includes a first object. The method for generating the source code includes: opening, by a computer system, the block diagram including the first subsystem in a model editor; generating, by the computer system, source code for the first subsystem, wherein generating the source code for the first subsystem includes determining information about the first subsystem; storing, by the computer system, the information about the first subsystem in the first object; and generating, by the computer system, source code for the block diagram, wherein the first object is read out to influence at least one parameter for generating the source code for the block diagram.

Abstract: A method for generating a technical system model executable on a test unit, wherein the test unit and the executable model are designed for real-time-capable testing of a control unit connected to the test unit, and wherein the executable model is constructed from a plurality of executable submodels communicating with each other, wherein each executable submodel has a separate address space and/or is executed on a separate processor or separate processor core when a test of a control unit connected to the test unit is being run.

Abstract: A method for event-based simulation of a system, the simulation comprising a first computing unit and at least one second computing unit, the first computing unit has a simulation time, the second processor has an operating system layer and an application layer. The second computing unit has a system time in the operating system layer, with at least the second computing unit executing a simulation application. At least one simulation object is executable on the simulation application, and the first computing unit manages an event queue, with at least one event per simulation step being listed in the event queue. The event is associated with a process to be executed by the simulation object and a simulation time provided for execution of the process.

Abstract: A method for visualizing system models in a model management environment, which includes the steps of opening the system model in the model editor, receiving a user input for rescaling a block, determining a relative horizontal position and a relative vertical position for each port in the block, calculating a new absolute horizontal and vertical position of each port in the block based on the relative horizontal and vertical position and the new size preset for the block, and displaying the block and each port in the block.
