Abstract

A method for determining a correctness of an actually received timestamp is provided. A communication network includes a master clock, a first ECU having a first slave clock, a validator having a second slave clock, and a first communication bus. The first ECU uses a first communication standard having a deterministic scheme. The method includes synchronizing, at the first ECU, a time of the first slave clock to a global time of the master clock, synchronizing, at the validator, a time of the second slave clock to the global time of the master clock, predicting, at the validator, a timestamp to be received in an actual communication cycle from the first ECU based on the deterministic scheme of the communication standard used by the first ECU, and comparing, at the validator, the predicted timestamp with the actually received timestamp from the first ECU.
