A torque steer compensation algorithm utilizing selected vehicle parameters, such as for example engine torque, accelerator pedal position, throttle position, transmission gear, and vehicle speed. Rates of change of the parameters are determined and compared to predetermined thresholds, whereby a torque steer factor is determined. The resulting torque steer factor is subsequently multiplied with a conventional, prior art predicted steering assist signal to arrive at a modified steering assist signal which is output to the coil of the steering column to reduce driver perception of torque steer at the steering wheel.
