Abstract
Disclosed is a driving force control device that includes a determination section (), a driving force command value calculation section (), and a command value output section (). The determination section () determines whether each of a plurality of motors (), which independently drive a plurality of wheels (), can be operated within a desired operating range when driven by a target driving force calculated for each of the motors (). The driving force command value calculation section () 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 if the determination means determines that each of the motors cannot be operated within the desired operating range. The command value output section () outputs the driving force command value to each of a plurality of inverters (). Therefore, a target vehicle motion can be maximally realized while appropriately maintaining the drive status of each of the motors.
