1. A driving force control device for an electric vehicle having a plurality of motors, which independently drive a plurality of wheels, and a plurality of inverters, which control a drive current for each of the motors in accordance with a driving force command value, the driving force control device comprising:

  • target driving force calculation means that calculates a target driving force for each of the motors in accordance with a vehicle operation performed by an operator of the vehicle or with the running status of the vehicle;

    determination means that determines whether each of the motors can be operated within a desired operating range when each of the motors is driven by the target driving force;

    driving force command value calculation means which, if the determination means determines that each of the motors cannot be operated within the desired operating range, adjusts the distribution of driving force for each of the motors in accordance with the target driving force for each of the motors and with the operating status of each of the motors and calculates an actual driving force command value for each of the motors for the purpose of operating each of the motors within the desired operating range; and

    command value output means that outputs the driving force command value to each of the inverters.
