Abstract

The disclosure relates to a method for synchronizing a clock-free computational node (26, 28) in a vehicle such that the clock-free computational node (26, 28) is able to perform an action at a pre-defined time. The method comprises generating a mapping between at least one current counter value received from the clock-free computational node (26, 28) and at least one current time information received from a clock unit (14). Moreover, the method comprises determining a pre-defined counter value being associated with the pre-defined time based on the mapping. Furthermore, the method comprises providing the pre-defined counter value to the clock-free computational node (26, 28). Additionally, a method for performing an action at a pre-defined time using a clock-free computational node (26, 28) is presented. Moreover, the disclosure is directed to a corresponding first computational node (12) comprising the clock unit (14) and a second computational node (26, 28) being clock-free. The disclosure also relates to a computational system (10) for a vehicle, comprising a first computational node (12) and at least one second computational node (26, 28).
