A method of reducing rollback of a electric vehicle, including determining a position baseline of the electric vehicle; determining a position compensated speed of the electric vehicle based on the position baseline; determining a hold torque as a function of the position compensated speed; and generating a command to apply the hold torque to the motor-generator of the electric vehicle.

Electric drive vehicle with anti-rollback control

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.
