Embodiment Construction

[0032]FIG. 1 shows a diagrammatic structure of a network system 10 according to one embodiment of the invention with a tree topology formed by a central network device 12, a plurality of switch devices 14 and a plurality of network components 16. In this arrangement, the network system 10 is designed as Ethernet network. The central network device 12 comprises a host 18, a network manager 20 (network manager module), a switch manager 22 (switch manager module) and a switch 24. The central network device 12 is connected via signals via a network segment 26 to a network component 18 and via three other network segments 28 to three switch devices 14 with switch 24, switch manager (switch manager module), 22 and host 18. The switch devices 14 are in turn connected via signals via network segments 26 to network components 16 and via other network segments 28 to other switch components 14, producing the tree structure.

[0033]To each of the network components 16, a first activation device 1...

Abstract

A method and system for activating at least one temporarily inactive network component of a network system for a vehicle, in particular a motor vehicle. A central network device of the network system is connected via signals to the network components by a path inside the network system, the path extending at least partially across a network segment of the network system. The network segment connects via signals the network component and a first activation device associated therewith to a switch device arranged in the path and to a second activation device associated therewith in an unbranched manner. The central network device responds to the first activation device by the switch device by sending a network function control signal.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a U.S. national stage of application No. PCT / EP2011 / 052456, filed on 18 Feb. 2011. Priority is claimed on German, Application No.: 10 2010 008 818.8, filed 22 Feb. 2010, the content of which is incorporated here by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a method for activating at least one temporarily inactive network component of a network system for a vehicle, especially for a motor vehicle.[0004]2. Prior Art[0005]Known network systems for vehicles, particularly motor vehicles, are based in most cases on serial bus systems. An example of such a bus system for networking various control devices for implementing system-wide functions of a vehicle is an asynchronous, serial bus system based on a CAN bus (Controller Area Network). Another example is a LIN: Local Interconnect Network Bus System. Since electrical power is supplied in many vehicles by an energy store of limite...
