利用离散点建立动力转向系统的摩擦力模型的方法
摘要：
本发明涉及一种评估辅助转向机构(1)中的摩擦力的方法，所述方法包括获取特征点序列的步骤(a)，在获取特征点的过程中，测量在转向机构的操作过程中与由辅助载荷连续获得的若干不同值对应的摩擦力值，从而凭经验获取独特的特征点序列(P1，P2，…Pn)，每个特征点将测得的摩擦力值(Fmes_1，Fmes_2，…Fmes_n)与代表辅助载荷的测量值(C致动_1，C致动_2，…C致动_n)关联，然后进行构造经验摩擦模型的步骤(b)，在该步骤过程中，基于所述特征点的所述序列形成的离散图，确立构成所述特征点序列的特征点(P1，P2，…Pn)之间的关联定律(L)。
摘要（英）：

A method for evaluating the frictions in a power steering mechanism, the method including a step of acquiring a series of characterization points, during which are measured, for several different values taken successively by the assistance force during the operation of the steering mechanism, the corresponding friction values, so as to empirically obtain a series of distinct characterization points each associating a measured friction value to a measured value representative of the assistance force, then a step of constructing an empirical friction model, during which a correlation law is established between the characterization points constitutive of the series of characterization points, from the scatter chart formed by the series of the characterization points.
