Abstract

Processing signals from messages on at least two data buses, particularly CAN buses in a vehicle, includes extracting at least one signal from at least one message in a traffic node of the at least two data buses and at least one extracted signal value of the at least one signal is checked for a change relative to the signal value of the at least one signal that was most recently held in the memory unit. The at least one extracted signal value of the at least one signal is held in the memory unit if the at least one extracted signal value of the at least one signal has changed relative to the signal value of the at least one signal that was most recently held in the memory unit.
