The invention provides a friction test method for a steering column and a vehicle, and the method comprises the steps: carrying out the overall measurement of at least two rotating friction pairs of the steering column, and obtaining the overall friction torque; independently measuring each rotary friction pair to obtain a single friction torque; the overall friction torque is compared with the sum of the friction torques of all the single bodies, and a comparison result is obtained; and verifying the accuracy of the overall friction torque according to a comparison result. In the technical scheme of the invention, each rotary friction pair in the steering column is independently measured to verify the accuracy of the measured overall friction torque of the steering column so as to ensure that accurate steering column friction test data is provided for steering system modeling.
本发明提供了一种转向柱的摩擦测验方法及车辆,其中,摩擦测验方法包括:对转向柱的至少两个旋转摩擦副进行整体测量,获得整体摩擦力矩;对各个旋转摩擦副进行单独测量,获得单体摩擦力矩;将整体摩擦力矩与各单体摩擦力矩之和进行比较,获得比较结果;根据比较结果,验证整体摩擦力矩的准确度。在本发明的技术方案中,通过对转向柱中的各个旋转摩擦副进行单独测量,以验证测得转向柱的整体摩擦力矩的准确度,以保证为转向系统建模提供准确的转向柱摩擦试验数据。
