Data logging or stimulation in automotive Ethernet networks using the vehicle infrastructure

摘要

The invention relates to a method and a device for recording data or for transmitting stimulation data, which are transmitted in Ethernet-based networks of vehicles. A method (400) for recording data is described wherein the data is sent from a sending controller to a receiving controller of a vehicle via a communication system (100) of the vehicle. The communication system (100) comprises an Ethernet network (110, 200), the data being passed from a transmit component (211) to a receive component (222) of the Ethernet network (110, 200) via a transmission path, and wherein the data is to be recorded at a logging component (230) of the Ethernet network (110, 200) that is not on the transmission path. The method (400) comprises configuring (401, 402) an intermediate component (220) of the Ethernet network (110, 200) which is located on the transmission path, a copy of the data as logging data to the logging component ( 230) to send; and recording (403) the logging data at the logging component (230).
