We investigate Brans-Dicke vacuum solutions in the presence of a cosmological constant A from the point of view of dynamical system theory. Assuming a Friedmann-Robertson-Walker metric we plot the phase diagrams corresponding to all values ofω. The analysis of the diagrams allows us to determine several physical properties of the solutions as well as their global dynamical behaviour.
