The dynamic phase transitions in a driven vortex lattice subject to quenched disorder are investigated by numerical simulations of the time-dependent Ginzburg-Landau-Lawrence-Doniach equations. We have considered a bilayered system as a prototype of multilayered current-carrying superconductors. Two transitions are examined: a dynamic melting transition, similar to single-layer systems, and a decoupling transition, which may occur only in a multilayered system. A universal structure of the phase-transition lines as functions of renormalized interlayer coupling and {open_quotes}shaking temperature,{close_quotes} which measures the disorder-induced effective Langevin force, is established. {copyright} {ital 1997} {ital The American Physical Society}
