1. A motor torque control apparatus for an automotive vehicle, comprising:

  • a transmission which has either one of a fixed speed ratio and a variable speed ratio;

    at least one motor-and-generator coupled with the transmission as a propelling power source of the vehicle, a power of the power source being transmitted to a road wheel for propulsion of the vehicle through the transmission; and

    a controller configured to be electrically connected to the motor-and-generator for motor torque control, the controller comprising (a) a disturbance observer that estimates a driving force; and

    (b) a motor torque control section that controls the driving force estimated by the disturbance observer, to bring the estimated driving force closer to a target driving force by way of servo control.
