Abstract
A method for controlling the response of an electric steering system by implementing damping for over-speed conditions is disclosed. The method includes the step of determining the velocity of an electric motor within the electric steering system, and determining a voltage limit value, wherein the voltage limit value is calculated as a function of the velocity of the electric motor. The method further includes the step of associating the voltage limit value with a motor voltage command in order to produce a limited voltage command, and applying the limited voltage command to the motor in order to provide a braking torque to the motor.
