摘要:
A computer-based system for testing a server-based vehicle function, which is designed to implement a method comprising the following steps: a function model of the vehicle function is simulated by a first simulator on a server, an at least partial vehicle model is simulated by a second simulator and the vehicle function is tested, while a data connection between the first simulator and the second simulator is systematically influenced.

摘要:
A system with a first computer unit and with a second computer unit, wherein the first computer unit comprises a first interface to enable connection to at least one sensor and to at least one actuator, wherein the second computer unit comprises a second interface to enable connection to at least one sensor and to at least one actuator, wherein the first and the second computer units can be connected to each other by means of a further interface, wherein the actuator comprises an interface, wherein depending on the first or on the second operating state the interface determines whether a control command for a driving function is adopted by the first or the second computer unit, so that in the first operating state only the first computer unit can activate the actuator and in a second operating state only the second computer unit can activate the actuator.

A subsystem for a vehicle includes a device management client for exchanging device, vehicle, and diagnostic as well as software update information, which is connected to a device management server of the back-end via an air interface, a download client for downloading a software update from the back-end into the vehicle, which is connected to a download server of the back-end via an air interface, software update clients for applying the software update, which are connected to the download client and a vehicle update client for coordinating the software update, which is connected to the download client and the software update clients.
摘要:
The present invention relates to a communications system (1) with at least one node (101, 102, 110), a control instance (10) and a shared communications medium (11). The at least one node is designed to receive messages that are or were transmitted in a first transmission mode. This first transmission mode has a lower data transmission rate and/or transmission complexity than a second transmission mode. The control instance (10) determines a first of the nodes in order to transmit data thereto in the second transmission mode or in order to release the shared communications medium (11) for the first node to transmit data in the second transmission mode. The control instance communicates this to the first node by means of a message (501, 502, 503, 504). This message is transmitted in the first transmission mode.

摘要:
The invention relates to a communications method that comprises the step of sending a query message from a central entity to at least one node. For every queried node, the central entity determines a node-specific time window based on a node-specific response time. The central entity filters out a response message, sent from the queried node, from the signals received during this time window. Based on the node-specific time window, the central entity assigns the response message to the queried node. The invention also relates to a computing unit that is configured to operate as a central entity, to a communications system, as well as to a computer program and a computer-readable storage program with said computer program.

The invention relates to a communications method that comprises the step of sending a query message (22) from a central entity (10) to at least one node (K1, K2, . . . , KN). For every queried node, the central entity determines a node-specific time window based on a node-specific response time (T1, T2, . . . , TN). The central entity filters out a response message (A1, A2, . . . , AN, B1, B2, . . . , BN), sent from the queried node, from the signals received during this time window. Based on the node-specific time window (Δ2), the central entity assigns the response message to the queried node. The invention also relates to a computing unit that is configured to operate as a central entity, to a communications system, as well as to a computer program and a computer-readable storage program with said computer program.
