摘要： Disclosed are a method and an operating system (BSY) for the timed operation of a network node in a distributed computer system (SYS) comprising at least two network nodes which are fitted for mutual data exchange by means of a time-controlled transmission protocol (ZUP). The time base (ZEI) on which the time-controlled transmission protocol (ZUP) is based is determined by a global clock (GZE) of the computer system (SYS). A local task controller (TST) is provided for controlling task processing based on at least one local time signal (ZES) of at least one local clock (LZE). The task controller is equipped so as to receive at least one respective time signal from both the global clock (GZG) and the local clock (LZG), at least one task in the network node being assignable to both the global clock (GZG) and the local clock, respectively. The task controller is also equipped for controlling processing of said tasks by using the at least one time signal of the respectively allocated clock.

摘要： A method and a fault-tolerant computer architecture to improve the performance in fail-safe trajectory planning for a moving entity. The method and FCTA uses a commander, that implements a sensor fusion stage and a trajectory planning stage , and a monitor that implements a sensor fusion stage, and a safe envelope generating stage. Sensors are monitoring the surrounding of the moving entity, and the sensor fusion stages accept sensor data as input. Based on said input the commander and the monitor produce as output real-time images of objects detected due to the monitoring of the one or more sensors. A trajectory planning stage of the commander generates trajectories based on said input, and the said safe envelope generating stage generates a safety envelope based said input. The commander provides the one or more trajectories to the monitor as well as to the decision subsystem.

摘要： A method for transmitting messages in a computer network, for example a TTEthernet computer network, wherein said computer network comprises nodes and at least one star coupler, which nodes and said at least one star coupler are connected in a multi-hop fashion, wherein nodes in said computer network periodically exchange time-triggered (TT) messages according to a pre-defined transmission schedule, and wherein nodes exchange, according to said transmission schedule, messages via scheduled time-triggered flows, wherein for adding a new time-triggered flow into the computer network, in particular into the running computer network, the following steps are carried out: 1. determining, for each hop in the new flow path of the new time-triggered flow, a free transmission gap in the transmission cycle of the corresponding port, 2. modifying, in case that a sufficiently long transmission gap is not free in a transmission cycle, said transmission cycle, wherein 3. modifying transmission cycles takes place iteratively, and 4. if a sufficient transmission gap is found in each transmission cycle along the flow path, the new transmission is incorporated into each of the transmission cycles and is executed periodically.

摘要： The invention relates to a method, in particular a time-controlled error-tolerant method, for periodically transporting real-time data in a computer system, in particular in a distributed computer system, said computer system comprising node computers (111 - 116), in particular a plurality of node computers (111 - 116), and distributor units (131, 132, 133, 151), in particular a plurality of distributor units (131, 132, 133, 151). The node computers and the distributor units have access to a global time, and real-time data is transported by means of messages, preferably by means of time-controlled real-time messages. The topology of the computer system corresponds to an intree, and node computers (111 - 116) are arranged on the leaves of the intree. One or more sensors (101 - 106) is assigned to each node computer (111 - 116), and the node computers (111 - 116) arranged on the leaves of the intree transmit sensor data in the payload of messages in the direction of a control center (100) located at the root of the intree at points in time, preferably at synchronized points in time. The payload of one or more incoming messages in a distributor unit is transported out of the distributor unit with an outgoing message, and an individual time plan is generated a priori for each distributor unit, wherein the time plan contains a periodically repeating starting time (391) for transmitting a message (390) going out of the respective distributor unit, said starting time being calculated a priori from - the a priori known time of arrival of a controlling payload to be transported, which is specified a priori for example, of one of the incoming messages, in particular a time-critical payload to be transported of one of the incoming messages, - minus the a priori known lead-time interval ([391, 393]) of the outgoing message (390), - plus at least one time interval ([393, 393)] required to copy a data element of the controlling payload, in particular the time-critical payload of the incoming message (320), into a data element of the payload of the outgoing message (390); and the payloads of the incoming messages are copied into the payload of the outgoing message by carrying out the a priori generated time plan.

The switch is configured to route frames received from the plurality of nodes to one or more of the plurality of nodes. At least one of the plurality of nodes is configured to store frames received from the switch in a buffer and to update the value in the dynamic delay field to reflect the end-to-end system delay.

摘要： The invention relates to a method for start-up of a network, the network consisting of a number of nodes, which are connected via channels, and wherein the nodes are able to exchange information in the form of messages via said channels. According to the invention the transition phase of a synchronizing node from its initial phase to a synchronized phase is separated in a first so-called integration phase and a second subsequent so-called cold-start phase. A synchronizing node in the integration phase is listening to messages being sent from nodes in the synchronized phase and only reacts to an integration message (i-frame) if said integration message is a valid message. Furthermore, a synchronizing node, in the case that integration of said synchronizing node to a set of already synchronized nodes was not successful after a specifiable period, changes into the cold-start phase, in which a cold-start procedure of the node is executed, wherein in the cold-start phase said node does not react to integration messages (i-frames) of a node in the synchronized phase.
