A method of controlling operation of an all-wheel-drive vehicle having independent power-sources includes driving the vehicle via at least one of a first power-source through a first set of wheels and a second power-source through a second set of wheels. The method also includes determining a rotating speed of each of the first and second sets of wheels relative to a road surface. The method additionally includes determining a road speed of the vehicle and determining a longitudinal acceleration of the vehicle. The method also includes determining a slip of the vehicle relative to the road surface using the determined rotating speed of each of the first and second sets of wheels and the speed of the vehicle. Furthermore, the method includes controlling the vehicle slip via regulating a torque output of the first and/or second power-source.
