摘要： 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.

摘要： An adapter for connecting an embedded system to a control computer having a standard interface, in particular a network interface, a first subcircuit, and a second subcircuit, the first subcircuit being designed to communicate with the control computer via the standard interface by means of a standard protocol, preferably XCP. The first subcircuit is designed to convert a protocol functionality requested in the standard protocol via the standard interface, out of a set of supported protocol functionalities into the call for one or more elementary functions out of a defined overall set of elementary functions. The first subcircuit is connected to the second subcircuit via an internal interface, wherein the second subcircuit has a programmable computing module which is configured to provide at least one elementary function out of the overall set of elementary functions which can be called up via the internal interface by means of a call.

摘要： A method for calibrating a target simulator for an active environment detection system includes: calibrating a complete signal path comprising a first signal path and a second signal path by determining a first deviation of a first value of at least one signal parameter from a first reference value of the at least one signal parameter; calibrating one of the first signal path and the second signal path by determining a second deviation of a second value of the at least one signal parameter from a second reference value of the at least one signal parameter; and calibrating the other of the first signal path and the second signal path by offsetting of the first deviation with the second deviation.

摘要： A method for testing a distance sensor includes: receiving an electromagnetic free-space wave as a receive signal; generating a simulated electromagnetic reflection signal therefrom; shifting a reflection frequency of the reflection signal by a Doppler frequency smaller than a signal bandwidth of the receive signal; converting the receive signal into a first work signal having a first work frequency smaller than a receive frequency of the receive signal; converting the first work signal into a second work signal having a second work frequency, wherein the difference between the first and second work frequencies is at least as large as the signal bandwidth plus the Doppler frequency; converting the second work signal into a third work signal having a third work frequency that corresponds to the first work frequency shifted by the Doppler frequency; increasing the third work signal by the conversion frequency; and radiating the third work signal.

摘要： A computer-implemented method for restructuring a predefined distributed real-time simulation network, wherein the simulation network has a plurality of network nodes and a plurality of data connections, wherein each network node has at least one data connection interface for connecting a data connection, wherein the network nodes are at least partially in communication via the data connections, and wherein during operation of the simulation network a simulation application is executed on at least one network node. The method permits a structure for the real-time simulation network to be automatically found in which the critical communication connections are reduced and avoided as much as possible by determining the topology of the simulation network so that topology information concerning the network nodes and the data connections between the network nodes is available by determining expected values for node data rates or node latencies for the network nodes of the simulation network.

摘要： A method for planning the design of partitions for a programmable gate array comprising different types of logic blocks of predetermined position, and a plurality of program routines comprising at least one first program routine and at least one further program routine. A mapping of a first partition of the programmable gate array with the first program routine and at least one further partition of the programmable gate array with the at least one further program routine is performed. The need of the first program routine for the individual types of logic blocks is determined. Meeting this need with the logic block resources of corresponding type available in the first partition. At least one logic block of corresponding type from the further partition or at least one of the further partitions into the first partition is transferred.

摘要： A method and replay unit for sending secured messages via a messaging system to a receiver ECU to be tested, wherein the replay unit is connected to the device under test via the messaging system, wherein the replay unit is set up to receive first secured messages to be replayed, to remove from the first secured messages a first counter value and a first authenticator, and to generate a second authenticator by means of a second counter value, an encryption algorithm and a key, and wherein the replay unit is set up to generate second secured messages by adding the second counter value and the second authenticator to the first messages, and wherein the replay unit is further adapted to send the second secured messages to the recipient device under test via the messaging system.

摘要： A checking apparatus can test at least one first closed-loop control unit. The checking apparatus can include a first timing transmission unit which can generate a first periodic timing signal from a first time signal, and which can output the first periodic timing signal to a first PLL. The check device can further include a first oscillator which can generate a second periodic timing signal and which can output the second periodic timing signal to a second PLL. The checking device can additionally include a first clock, and can forward a first clock signal to a first input/output unit, and/or to a first computation unit. A first changeover signal can be used to control a first multiplexer such that depending on a state of the first changeover signal, the first multiplexer can forward either a first frequency-stabilized timing signal or a second frequency-stabilized timing signal to the first clock.

摘要： A computer-implemented method for generating program code based on one or more blocks of a block diagram, at least one block including a block variable. The method comprises opening the block diagram in a model editor, retrieving generation settings for the block variable from a data definition tool, the generation settings comprising a scope of the variable, determining that a modification rule is referenced in the generation settings, and retrieving the referenced modification rule from the data definition tool, wherein a modification rule comprises a filter condition and one or more code changes. A processor generates program code based on the block diagram and the generation settings and applies the referenced modification rule to the block variable in the generated code, which includes verifying that the filter condition is fulfilled for the block variable and applying the code changes to each occurrence of the variable in the code.

摘要： A method for computer-based simulation or control of a dynamic system using a computer includes: cyclically receiving, by a programmable logic device, at least one input signal; calculating, by the programmable logic device, at least one matrix multiplication; and outputting, by the programmable logic device, at least one output signal. A configuration of the programmable logic device includes: a parallel multiplication of blocks of at least two elements of a matrix by at least one input-signal-dependent element of a vector, and an adder tree for multiplication results. Successive blocks of the matrix are temporarily stored in a pipeline and processed sequentially. A target number of blocks and a target adder stage are determined based on a number and/or values of parameters of at least one system equation. Processing of blocks for a current cycle is terminated based on the target number of blocks and the target adder stage being reached.
