Abstract
A method for synchronizing a clock-free computational node in a vehicle such that the clock-free computational node is able to perform an action at a pre-defined time, including generating a mapping between at least one current counter value received from the clock-free computational node and at least one current time information received from a clock unit. Moreover, the method includes determining a pre-defined counter value being associated with the pre-defined time based on the mapping. Furthermore, the method includes providing the pre-defined counter value to the clock-free computational node. Additionally, a method for performing an action at a pre-defined time using a clock-free computational node is presented. The disclosure is directed to a corresponding first computational node including the clock unit and a second computational node being clock-free and a computational system for a vehicle.
