ABSTRACT:
A system provides feedback to an operator of a steer-by-wire system. In steer-by-wire systems, there is no direct mechanical connection between the vehicle steering wheel and the steering gears. The present invention utilizes a sensor to sense torque values at the steering gears. The sensor communicates signals back to the steering wheel as operator feedback. The sensed and communicated torque values include high frequency torque fluctuations to provide road-feel in steer-by-wire systems. Also, the torque can be used to make predictions of the operator's conditions and the condition of the steering system.
