Title: METHOD FOR DETERMINING A MASTER TIME SIGNAL, VEHICLE, AND SYSTEM
Abstract:
The invention relates to a method for determining a master time signal (MZ), in particular in a vehicle, comprising the following steps: a) receiving at least one first server time signal (SZ1) from a first time server (10); b) receiving at least one second server time signal (SZ2) from a second time server (20); c) comparing the first server time signal (SZ1) with the second server time signal (SZ2) in order to determine at least one first time difference (ZD); d) storing the first time difference (ZD); e) determining the availability of the first server time signal (SZ1) and/or of the second server time signal (SZ2); f) using the stored first time difference (ZD) to determine the master time signal (MZ) at least if at least one of the server time signals (SZ1; SZ2) is not available.
