The present invention ensures the required coupling capacity precision of a friction coupling element by appropriately switching a torque sharing rate during a shift transition period. Provided is a control device for an FR hybrid vehicle equipped with a motor/generator (MG), an automatic transmission (AT), an AT controller (7), a second clutch (CL2), a control unit (71) for switching the CL2 torque sharing rate, a torque/oil pressure command converter (72), and an oil pressure/electric current command converter (73). The second clutch (CL2) is disposed in a power transmission path from the motor/generator (MG) to left and right rear wheels (RL, RR). The control unit (71) for switching the CL2 torque sharing rate delays switching the torque sharing rate of the second clutch (CL2) during a shift transition period until the start of the shifting procedure, and continuously switches the current gear sharing rate to a subsequent gear sharing rate in accordance with the degree of the shifting procedure when the shifting procedure starts.
