Abstract: A method for synchronizing clocks in nodes of a vehicle network of a motor vehicle corrects a time difference between a master clock and a slave clock, taking into account transmission delay for a message between a master node and a slave node. At least for a first synchronization of the master clock to a slave clock after the nodes of the vehicle network are started up, a default transmission delay in the slave node is used to correct the time difference, and/or the slave node sending out a Delay Request message, and recording in the master node the time at which Delay Request message is received and the master node sending the time, as a Delay Response message, back to the slave node. In the slave node, the transmission delay for a message between the master node and the slave node is determined.

Abstract: A method for transmitting data in a packet-oriented communications network, in particular of a motor vehicle, with a guaranteed maximum transmission time for the data packets in the communications network, and to a user terminal for carrying out said method. According to the method, before the data transmission a specific quality of service is reserved by a reservation request from the sender of the data to the receiver of the data. The reservation request including the data rate of the data stream and the latency as parameters of the requested quality of service. Once the reservation request is confirmed, the requested quality of service for the communication link between the sender and the receiver is guaranteed in the network for the data stream. In addition, the quality of service for the data stream is adjusted by the sender on the basis of the topology of the communication network and/or the resources of the communication link.

Abstract: A method for transmitting data in a packet-oriented communications network, in particular of a motor vehicle, with a guaranteed maximum transmission time for the data packets in the communications network, and to a user terminal in the communications network. In the method, a specific quality of service as a capacity of the communication link is reserved prior to a data transmission by a reservation request from the sender of the data to the receiver of the data and the requested quality of service as a capacity of the communication link between the sender and the receiver is guaranteed in the network for the data stream by the confirmation of the reservation request, or an indication is given by a rejection that transmission is not possible. In addition, the capacity of the communications network is determined cyclically prior to a reservation request, after a rejection and/or at predefinable time intervals.

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.
