                         phase-field crystal model for driven adsorbed atomic layers is 
                         determined numerically. The model describes the layer as a 
                         continuous density field coupled to the pinning potential of the 
                         substrate and under an external driving force. Dynamical equations 
                         which take into account both thermal fluctuations and inertial 
                         effects are used for numerical simulations of commensurate and 
                         incommensurate layers. At low temperatures, the velocity response 
                         of an initially commensurate layer shows hysteresis with dynamical 
                         melting and freezing transitions at different critical forces. The 
                         main features of the sliding friction behavior are similar to the 
                         results obtained previously from molecular dynamics simulations of 
                         particle models. However, the dynamical transitions correspond to
