Abstract
A method for securing time synchronization in a server Electronic Control Unit (ECU), including: initializing time synchronization of the components; storing a unique clock identification of a grandmaster clock; identifying a shadow controller; transmitting synchronization messages; querying the sending time with the shadow controller; inserting the time in the follow-up message via the controller that forms the grandmaster clock, and retransmitting the time; sending additional messages relating to time synchronization via selected network devices that do not provide the previously determined grandmaster clock. The time information sent in the additional messages relating to time synchronization and the clock parameters relevant for determining the best clock by Best Master Clock Algorithm (BMCA) and the domain number match those of the previously determined grandmaster clock, or are comparable with them. The additional messages relating to time synchronization contain a unique clock identification corresponding to the identification of the respective selected network device.
