DRIVING FORCE CONTROL APPARATUS FOR ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an electric vehicle achieving target vehicle motion to the maximum extent while properly holding a driving state of each motor.

SOLUTION: A driving force control apparatus 10 for the electric vehicle includes: a plurality of motors 106 which independently drive a plurality of wheels 107; and a plurality of inverters 105 which control drive current to the respective motors on the basis of a driving force command value. This control apparatus also includes: a determination part 12 which determines whether the respective motors can be operated within a desired operation range when driving is performed at the target driving force calculated for each motor; a driving force command value calculation part 13 which adjusts the distribution of the driving force of the respective motors on the basis of the target driving force for each motor and operation states of the respective motors, and calculates an actual driving force command value for each motor in order to operate the respective motors within the desired operation range when the determination part determines that the respective motors cannot be operated within the desired operation range; and a command value output part 14 which outputs the driving force command values to the plurality of the inverters, respectively.
