The present invention relates to a method and a system to control steering force according to power of a driver, capable of estimating power of a driver with the weight of the driver, and controlling steering force depending on whether hand torque exists in a reference range or not by selecting a corresponding current table by recognizing positions of a steering wheel and a seat. According to the present invention, the system includes a torque sensor installed on a steering shaft, rotating with the steering wheel by being connected to the steering wheel, and sensing torque, applied by the driver to the steering wheel; a steering sensor sensing a rotation angle, generated by the rotation of the steering wheel; a motor part generating rotational force to be delivered to the steering shaft; a weight sensor installed on the bottom of the seat, on which the driver sits, to sense the weight of the driver; a current table storing a rotation angle, a torque value, a current value, and the power of the driver according to the weight of the driver; and an electronic control unit (ECU) estimating the power of the driver according to the weight of the driver, and controlling steering assistance force of the steering wheel by controlling the estimated power according to the current value.
