The purpose of the present invention is to prevent shock from occurring due to the intervention of regenerative control while operating in the four-wheel drive state. The drive source has a motor/generator (4), and an electronically controlled coupling (42) is provided on the drive power transmission path leading from the drive source to the front and rear wheels. This FF base four-wheel drive hybrid vehicle is comprising a 4WD control unit (85) that outputs to the electronically controlled coupling (42) a transmission torque command value to bring about the four-wheel drive state, in accordance with the vehicle state. The 4WD control unit (85) has a regenerative control intervention-coordinating controller that, when regenerative control by the motor/generator (4) has intervened during the four-wheel drive state, brings the transmission torque of the electronically controlled coupling (42) to zero before initiating regenerative control.
