Embodiment Construction

[0051] exist figure 1 A schematic diagram of a first embodiment of a network device is shown in . These figures also serve to explain the method for operating the network arrangement.

[0052] figure 1 A network device 101 is shown, which can be used in a vehicle, for example, as an Ethernet network. Here, three network devices 1 , 201 , 301 are shown by way of example. For example, it can be a control component. The network devices 1 , 201 , 301 , also referred to below as network nodes or control components, each have redundant control devices 2 , 3 , 202 , 203 , 302 , 303 . A network device 1 , 201 , 301 may also be referred to as a user of the network.

[0053] The control devices 2, 3, 202, 203, 302, 303 are adapted to perform certain tasks or functions. This can be, for example, sensor detection or actuators. The control device can also be implemented as a CPU or microprocessor. For example, it is conceivable that the control unit 1 is designed for detecting a pe...

Abstract

The invention relates to a method for operating a communication network (101), in particular an Ethernet network. Network devices (1) which are coupled to the network comprise a switch device (4), first and second control devices (2, 3) which are coupled to the switch device (4). The switch device (4) comprises for the first and second control devices (2, 3) a respective input port (10, 14) and an emitter port (9, 13) for sending and receiving data via the communication network (6). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure by using bidirectional communication paths. The invention further relates to a network arrangement (101) comprising a plurality of corresponding network devices (100, 200, 300) which operate according to the method.

Description

technical field [0001] The invention relates to a method for operating a communication network and a network arrangement which operates with the proposed method. This operating method can be used in particular in an Ethernet environment. Background technique [0002] Communication networks are increasingly used to measure, control and regulate complex technical systems. For example, networks are increasingly used in automobiles to constitute vehicle control systems. In correspondingly complex and safety-relevant technical systems, high demands are placed on the availability of control elements provided as network devices. In the event of failure of individual components, such as sensors or control units, this must not lead to failure of the overall system. Drive-by-wire systems are particularly safety-relevant in which the steering wheel position is converted into the wheel position electrically via a network coupling of sensor, control and actuator devices. [0003] In ...
