Abstract

A system for determining driver torque includes a rack torque estimator module that determines an estimated rack torque value based on a motor angle, and a motor velocity. The system further includes a driver intent detection module that computes a disturbance torque scaling factor based on the estimated rack torque value. The system further includes a blend module that generates a motor torque assist command based on a scaled value of the estimated rack torque value using the disturbance torque scaling factor.
