摘要： The present invention includes a system and a method for generating steering reaction torque in a steer-by-wire steering system. The system includes a manually steerable member; a feedback generator; a vehicle speed sensor; a steering position sensor; and a steering actuator load sensor. A control unit calculates a set of blended reaction torque values by receiving input signals from the steering position sensor and the steering actuator load sensor. The control unit operates on the input signals and computing a set of reaction torque values, and blending the reaction torque values into set of blended reaction torque values. The set of reaction torque equations comprises a plurality of non-linear functions that is adapted for real-time, continuous operation upon the input signals from the sensors. The set of blended reaction torque values is speed-sensitized based on vehicle speed and transmitted to the feedback generator to generate steering feel in the manually steerable member.
