Abstract: A method for transmitting data using an Ethernet AVB transport protocol between nodes of a motor vehicle includes: reserving resources necessary for the transmission of the data by reservation messages from a dedicated protocol; setting flow of data from a node to a particular transmission rate and/or data rate; transmitting data at cyclic intervals via an Ethernet-based network by inputting the data into a transmission frame and forwarding to local transmitters; deactivating the local transmitters and receivers of a node in non-use periods, in which no data need to be transmitted; activating again the local transmitters and receivers of a node provided that data are pending transmission in a transmission frame, wherein the local transmitters and receivers are available for transmission following an activation time; and activating the local transmitters and/or receivers of the nodes based on a reservation message and a setting of the transmission rate and/or data rate.

Abstract: A method for transmitting data in a motor vehicle from an application using an Ethernet transport protocol between nodes of the motor vehicle includes: the application transmitting data via an Ethernet-based network at cyclic intervals; deactivating local transmitters and receivers of a node in non-use periods, in which no data need to be transmitted; activating again the local transmitters and receivers of the node when data are pending transmission; transferring the local transmitters and receivers from an operating active mode to a quiescent mode in a deactivation time; transferring the local transmitters and receivers from the quiescent mode to the operating active mode in an activation time; and the application lowering the transmission frequency at least until a prescribed limit value is reached based at least in part on a requirement to save energy.

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.

Abstract: In a vehicle network in which controllers of the vehicle form nodes communicating with one another, wherein a group of the controllers to be activated is combined in a subnetwork to be activated, wherein each node has at least one network interface to an adjacent node directly addressable via the network interface, and a subnetwork manager indicating which network interface a node can use to communicate with which subnetwork, a method activating deactivated controllers includes: upon receipt of an activation command by the controllers of a subnetwork, a node identifying in the subnetwork manager which network interfaces the subnetwork manager can use to communicate with the subnetwork to be activated; the node using the identified network interfaces to transmit the activation command to adjacent nodes; and upon the transmission of the activation command, activating an adjacent node if the adjacent node was deactivated prior to transmission of the activation command.
