Abstract: A method of controlling torque of an electric vehicle, including sensing a surface grade; determining an acceleration of the vehicle; determining an initial torque of the vehicle; estimating a weight of the vehicle based the surface grade, the acceleration, and the initial torque; converting the weight of the vehicle to a weight factor; and determining an output torque by applying the weight factor to the initial torque.
