To provide a vehicle equipped with a plurality of motors for outputting power to a plurality of axles, in which power balance is more properly performed, and unexpected charging/discharging of an electrical storage device is suppressed.
Correction processing is applied to required front wheel torque Tfd and required rear wheel torque Trd to be calculated by required torque T* and front and rear wheel torque distribution ratios Df and Dr, so that front wheel command torque Tf* and a rear wheel command torque Tr* can be set (S110 to S160), and a motor use upper and lower limit powers or motor upper and lower limit torque are calculated based on the front wheel command torque Tf* and the rear wheel command torque Tr* and input and output limits Win and Wout of a battery (S180, S190), and torque commands Tm2* and Tm3* of motors MG2 and MG3 are set with restriction by the motor upper and lower limit torque, and the motors MG2 and MG3 are driven (S200 to S220). Thus, it is possible to more properly perform power balance, and to suppress the unexpected charging/discharging of the battery 50.
