The apparatus for controlling a steering assist system providing steering assist in response to a steering control signal, comprises a motor position sensing device for sensing the relative position between the variable reluctance motor's rotor and stator, and first and second torque look-up tables, each of the first and second torque look-up tables having motor current values that vary as a function of motor position. The control device operatively connected to the motor position sensing device, determines a first motor current value by interpolating between two current values corresponding to the two motor positions stored in the first look-up table closest to the sensed motor position, determines a second motor current value by interpolating between two current values corresponding to the two motor positions stored in the second look-up table closest to the sensed motor position, and determines a final motor current value by interpolating between the first and second determined motor current values. A motor control signal is provided in response to the determined final motor current value. |
