The invention relates to a method for determining a friction torque (FR1, FR2) applied in a steering column (5) of an electric power steering system (1) comprising a steering column provided with a torsion bar (11) subject to an instantaneous torsional moment (Ct), linked to a pinion capable of driving a rack, a torsion bar sensor (12) for measuring the instantaneous torsional moment, the method comprises an acquisition step (103) during which at least one value of the friction torque is measured by the torsion bar sensor, the acquisition step being performed after receiving a trigger signal, the value of the trigger signal depending on the value of the conditional variable (VL, A, V, C, [Delta] C, [Delta] A).
本发明涉及一种用于确定施加在电动动力转向系统(1)的转向柱(5)内的摩擦扭矩(FR1、FR2)的方法,该动力转向系统包括转向柱,该转向柱设置有承受瞬时扭转力矩(Ct)的扭力杆(11),该转向柱链接到能够驱动齿条的小齿轮,扭力杆传感器(12)用于测量瞬时扭转力矩,该方法包括采集步骤(103),在该采集步骤期间,摩擦扭矩的至少一个值由扭力杆传感器测量,采集步骤在接收到触发信号之后执行,触发信号的值取决于条件变量(VL、A、V、C、ΔC、ΔA)的值。
