Abstract

A method, a device, and a bus system for synchronizing at least two TTCAN buses having at least one bus user, there being cycle times of the basic cycles in the TTCAN buses, a global time being determined in each TTCAN bus and the deviations of the global times of the TTCAN buses which are linked together by at least one user being determined from the global times, and the deviations of the individual global times being transmitted to at least one bus user, the cycle times of the TTCAN buses, which are connected by at least one user, being mutually adjusted as a function of the deviations in the global times in such a way that the buses are synchronized with respect to the cycle times.
