Summary: | A method for generating a compensated torque command signal (116) to be applied to an electric power steering motor (36) is disclosed. In an exemplary embodiment, the method includes generating an assist torque command signal (64) responsive to a measured vehicle speed (42) and an input steering torque signal (50). An assist dependent damping torque signal is generated, the assist dependent damping torque signal responsive to the assist torque command signal (64), the measured vehicle speed (42) and a compensated motor velocity output value (104) of the electric power steering motor. The assist dependent damping torque signal is then subtracted from the assist torque command signal (64). |
