Method for activating a network component of a vehicle network system

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.

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...

AI Technical Summary

Benefits of technology

[0011]The network component is an electrical device, particularly a control device of a vehicle component of the vehicle, preferably of the motor vehicle. To minimize the energy demand of the vehicle, the electrical device is temporarily inactivated when it is not needed.

Problems solved by technology

However, this technology is unsuitable for use in the automotive or motor vehicle field since the network controllers themselves must be active or at least partially active to recognize such a packet.

As a result, the demand for quiescent current is distinctly too great for an automotive environment.
