Method for activating a network component of a motor vehicle network system
First Claim
1. A method for activating at least one temporarily inactive network component of a network system for a vehicle, comprising:
- connecting, for signal communication, a central network device of the network system to the at least one temporarily inactive network component via a path inside the network system, which leads at least partially across a network segment of the network system;
connecting, for signal communication, the at least one temporarily inactive network component and its associated first activation device via the network segment, the first activation device being directly connected in an unbranched configuration to only a switch device and an associated second activation device, wherein the switch device is arranged between the central network device and the at least one temporarily inactive network component;
addressing, by the central network device, the first activation device by the switch device by sending a network function control signal;
activating the at least one temporarily inactive network component by the first activation device in response to the network function control signal; and
sending, by the first activation device subsequent to activation, a further network function control signal to a second activation device that confirms the activation.

Abstract
A method and system for activating at least one temporarily inactive network component of a network system for a vehicle central network device of the network system is connected via signals to the network component by a path inside the network system extending at least partially across a network segment of the network system. The network segment connecting, 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.

8. A network system of a vehicle, configured to activate at least one temporarily inactive network component, comprising:
-
a path within the network system, the path leading at least partially across a network segment of the network system; a switch device; a central network device connected directly to the at least one temporarily inactive network component for signal communication via the path within the network system; a first activation device associated with the at least one temporarily inactive network component and directly connected via the network segment for signal communication unbranched to only the switch device and configured to be addressed by the central network device by a network function control signal sent by the switch device; and a second activation device associated with the switch device, wherein the switch device is arranged between the central network device and the at least one temporarily inactive network component, and wherein the first activation device is configured to send a further network function control signal to the second activation device for confirming the activation. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
