The EPS system generates assist torque to assist steering effort through the operation of the motor installed on the power steering gear assembly.

The direction and amount of power assistance are determined by signals from the torque sensor, and controlled in accordance with vehicle speed. As a result, steering effort is controlled to be light during low speed driving and moderately high during high speed driving.
