A method for determining a friction torque exerted within a steering column of an electric power steering system, the power steering system comprising a steering column provided with a torsion bar undergoing an instantaneous torsion torque, the steering column being linked to a pinion capable of driving a rack, a torsion bar sensor intended to measure the instantaneous torsion torque, the method comprising an acquisition step, during which at least one value of the friction torque is measured by the torsion bar sensor, the acquisition step being carried out following the reception of a trigger signal, the value of the trigger signal depending on values of conditional variables (VL, A, V, C, ΔC, ΔA).
