Method for transmitting data between nodes of a motor vehicle using an ethernet-AVB transport protocol and control unit configured to carry out said method

摘要

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.
