Zusammenfassung:	There is provided a hybrid-vehicle controller that can calculate MG demand torque with which fuel consumption in an engine can efficiently be decreased by increasing the MG's power-running torque. In the hybrid-vehicle controller, from a plurality of MG torque candidate values, there are selected the MG torque candidate values that make a 0 MG-torque-reference total supply power variation amount become the same as or smaller than a power-running-side variation amount upper limit value; then, there is selected, as a power-running-side final MG torque candidate value, the MG torque candidate value that makes an absolute value of the relative supply power variation amount ratio become maximum, among the selected MG torque candidate values.
