Abstract
The invention relates to a method for determining the control unit temperature in a motor vehicle by means of Ethernet, comprising the steps of: determining a transit time of a first signal on a first connection path between a first server ECU of the Ethernet vehicle electrical system and a second server ECU of the Ethernet vehicle electrical system; determining a maximum speed of the first connection path on the basis of the transit time; identifying at least a first server ECU of the Ethernet vehicle electrical system; synchronising at least a first server ECU of the Ethernet vehicle electrical system; determining the synchronisation interval; determining a timestamp of the first server ECU; reading a timestamp or querying the clock time of the first server ECU; comparing the timestamp with a reference clock of the Ethernet vehicle electrical system; carrying out a transit time measurement; determining the speed of the associated clock generator; determining the time difference of the synchronisation interval; determining the last synchronisation.
