Abstract
An electric vehicle driving force control device capable of decreasing discrepancy generated between a driver's acceleration pedal operation and output torque actually generated by a drive motor is provided. The electric vehicle driving force control device includes target torque setting unit 5, 7, 8, 9, and 10 for setting target torque by limiting an upper limit of a target torque basic value from the target torque basic value and the maximum discharge power equivalent motor torque. The target torque setting unit corrects the target torque basic value such that, on a graph indicating a relationship between an acceleration opening and the target torque, an acceleration opening generating a limited target torque shifts to an acceleration opening side greater than the acceleration opening, and target torque smaller than the target torque basic value is generated in an accelerator opening region which is smaller than the limited accelerator opening.
