Abstract
A driving-force controller for an electric vehicle including at least two motors that independently drive left and right wheels, includes a detector that detects driving operation by a driver, and a controller that calculates a demand torque Tr of the driver, the torque difference ΔT applied to the left and right wheels during cornering, left and right torque-difference maintaining torques TLK and TRK of the motors when generating the demand torque Tr while maintaining the torque difference ΔT, and controls the motors based on the torque-difference maintaining torques TLK and TRK. The controller determines the priorities of a demand torque mode that generates the demand torque Tr and a torque difference mode that generates the torque difference ΔT depending on the driving operation detected by the detector.
