ABSTRACT:
A driving-force regulating apparatus for an electric vehicle, including a first device which regulates, when the accelerator is operated, an output torque of the electric motor to a running torque corresponding to (A1) an operation amount of the accelerator and (A2) a rotation speed of the motor; a second device which regulates, when the vehicle satisfies a predetermined condition, the output torque of the electric motor to a creep torque corresponding to (B) one or more conditions of the vehicle; and a third device which regulates, when the accelerator is operated after termination of the creep torque regulation, the output torque of the motor to an after-creep torque corresponding to (B) the one or more conditions of the vehicle, (C1) an after-creep operation amount of the accelerator, and (C2) an after-creep rotation speed of the electric motor, the third device regulating the output torque of the motor such that the after-creep torque is different from a running torque to which the output torque of the motor is regulated in response to a same operation amount of the accelerator as the after-creep operation amount and a same rotation speed of the motor as the after-creep rotation speed.
