Abstract
A method for validating time synchronization in a communication network of an automated vehicle includes sending a time synchronization message from a master clock to two control units of a first communication network, respectively, wherein the time synchronization message includes a master time; synchronizing a local time of the two control units of the first communication network to the received master time, respectively; sending the synchronized local times of the two control units of the first communication network to a central validator of the first communication network, respectively; comparing, at the central validator of the first communication network, the received synchronized local times of the two control units of the first communication network to each other; and, if a difference between the received synchronized local times is larger than a predefined first threshold, outputting an error message from the central validator of the first communication network to the automated vehicle.
