The invention relates to a friction torque learning and compensating method and system for a steering system, the steering system comprises a power-assisted steering unit, and the learning and compensating method comprises the following steps: receiving current driving state information of a vehicle attached to the steering system; judging whether the current driving state information meets a preset friction torque learning condition or not; when the current driving state information meets the friction torque learning condition, calculating and storing the friction torque of the steering system; and controlling the power steering unit to perform friction torque compensation according to the calculated friction torque. The friction torque can be continuously learned according to the current driving state information of the automobile, the power-assisted steering unit can be controlled to update the new friction torque in time so as to compensate the influence of the friction torque on the steering hand feeling, and the hand feeling consistency of a steering system in the whole service life of the steering system is guaranteed.
