The invention relates to a method for transmitting messages via a bus structure comprising a station s and several stations x e ELEMENT X:= {a, b, c,...}, wherein messages can be transmitted from said station s to a station x and vice versa. Before the transmission of a message at a desired send time txs w(k), tsx w(k), k e ELEMENT {0, 1, 2, ... }, a station x, s checks whether the bus is already being used for transmitting a message by another station x, s. The station x, s only transmits the message if the bus is not being used. Otherwise, the send time for the message is shifted by a random period of time to a send time txs r(k), tsx r(k). According to the inventive method, the desired send times tsx w(k+n), txs w(k+n), n e ELEMENT {1, 2, 3, ... } of successive transmissions are shifted in such a way that the difference between the desired send time txs w(k+n), tsx w(k+n) and the actual send time txs r(k+n), tsx r(k+n) is always below a threshold value. |
