Method for friction compensation in power steering system and associated estimation method

The aim of the invention is to overcome some or all of the cited disadvantages. To this end, a method is provided in which a continuous estimation of the intermediate friction rate is carried out, allowing the integration of said method into an general friction compensation method so as to continuously improve the feel on the steering wheel, particularly for speeds below a determined threshold. The invention therefore relates to a method for friction compensation in an electrical power steering system, characterised in that the compensation method takes into account a continuous estimation ofthe intermediate friction rate obtained by the estimation method according to the invention. 本发明的目的是克服一些或所有引用的缺点。为此，提供一种方法，其中中间摩擦率的连续估算被执行，从而允许将所述方法集成到一般的摩擦补偿方法中，以便持续改善方向盘的感觉，特别是对于低于确定的阈值的速度。因此，本发明涉及一种用于电子动力转向系统中的摩擦力补偿的方法，其特征在于，该补偿方法考虑了对通过根据本发明的估算方法获得的中间摩擦率的连续估算。
