Abstract: Right front wheel units (FL, FR) are driven independently by motor generators (MGL, MGR). A power control unit (1) is provided common to the motor generators (MGL, MGR) and integrally controls driving them. Each motor generator (MGL, MGR) and the power control unit (1) are selectively connected by switch circuits (SWL, SWR). The switch circuits (SWL, SWR) are switched by an ECU (3), as appropriate, in accordance with how the vehicle (100) is currently traveling (i.e., a driving force that the vehicle is required to output, and a direction in which the vehicle is traveling). In other words, the vehicle (100) can selectively implement traveling with the left and right front wheel units (FL, FR) both serving as driving wheel units, and traveling with only one of the left and right front wheel units (FL, FR) serving as a driving wheel unit, depending on how the vehicle is currently traveling.

Abstract: Front left and right wheel units (FL, FR) are driven by an engine (ENG) and a motor generator (MG2). Rear left and right wheel units (RL, RR) are independently driven by in-wheel motor type motor generators (MGR, MGL). The motor generator (MG2) and the motor generator (MGR, MGL) are configured to have different rated outputs, respectively, and be subjected to different speed reduction ratios, respectively, between the motor generators and their respectively associated drive wheel units, and thus have characteristics, respectively, in efficiency with respect to torque and vehicular speed, that exhibit high efficiency in mutually different output ranges, respectively. When a mileage oriented mode is selected as a traveling mode, an ECU (30) determines how a drive torque should be allocated between the motor generators (MG2, MGR, MGL), as based on the motors' required drive torque and vehicular speed and on each motor generator's characteristic in efficiency, to maximize the motor generators' total efficiency.
