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.

Computer-based system for testing a server-based vehicle function

The present invention relates to a communications system () with at least one node (), a control instance () and a shared communications medium (). 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 () 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 () 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 (). This message is transmitted in the first transmission mode.

Communications system with control of access to a shared communications medium

The invention relates to a method for processing at least one data packet () which comprises a first header () and a payload (), wherein the first header () is processed by a first mode and the payload () is processed by a second mode, wherein a number of processing steps () for carrying out the second mode is greater than a number of processing steps () for carrying out the first mode, the two modes being performed separately from one another.

Method for processing a data packet

In a method for storing data in a motor vehicle: an application software executed on a control device of the motor vehicle connects, via a communication network of the motor vehicle, to a data storage device of the motor vehicle; the application software logically connects the connected data storage device to the control device; the application software accesses the connected data storage device via the communication network, and the application software optionally releases the connected data storage device.

Device for storing data in a motor vehicle

A method for updating firmware of a vehicle via an air interface, in which data are exchanged with a backend via the air interface through a connection module, the data are managed by a data management module inside the vehicle, the connection module and the data management module are coordinated by a coordination layer, the connection module and the coordination layer are monitored by a monitoring layer, and the data are requested as needed by the coordination layer for an installation.

Method and device for the robust updating of firmware of a vehicle via an air interface

A method is provided for regulating a Quality of Service in a local area network, including the following: a Quality of Service regulator receives at a gateway of the local area network, from at least one Quality of Service checker, a status report concerning a distributed application; the Quality of Service regulator establishes, based on the status report, traffic engineering rules pertaining to the gateway; and the Quality of Service regulator transmits the traffic engineering rules to a Quality of Service controller. A corresponding device, a corresponding computer program and a corresponding storage medium are also provided.

Method and device for regulating a quality of service between a local area network and a wide area network

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.

Modular subsystem for a vehicle for updating and device management

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.

Communications method in a communications system

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.

Fail-safe EE architecture for automated driving

In a having a plurality of levels, each level has at least one information node; a number of information nodes of a lower k+1-th level are assigned to an information node of a k-th level configured thereabove and linked to this one information node; one information node of the lower k+1-th level is designed to inform the information node of the k-th level configured thereabove, which pieces of information the information node of the k+1-th level needs, and which pieces of information the information node of the k+1-th level is making available.

Network

In a method for processing messages with the aid of at least one Ethernet controller having a message store, the at least one Ethernet controller checks a received message for the presence of at least one property, and the received message is stored in the message store if this at least one property applies to the message.
