    • The present invention is a driving control method of a tire testing machine provided with a controller for giving a rotation command to a tire driving electric motor so that a slippage ratio of a tire with respect to movement of a simulated road surface is a preliminarily fixed value, and changing rotation speed of the tire, the method comprising: estimating longitudinal force imposed on the tire in accordance with the slippage ratio of the tire in a case where the rotation command is given; determining a torque limitation value for the tire driving electric motor based on an estimated longitudinal force estimate value; and applying the torque limitation value to torque limitation of the tire driving electric motor when the rotation command is given so as to change the rotation speed of the tire. With such a configuration, in a case where a tire test is performed while changing the slippage ratio, it is possible to perform the test without imposing excessive overloads on the tire driving electric motor.
    • 本发明是一种轮胎试验机的驱动控制方法,该轮胎试验机具有向轮胎驱动用电动机赋予旋转命令的控制器,使得轮胎相对于模拟路面的移动的滑动比为预先设定的值 并且改变轮胎的转速,所述方法包括:在给出旋转命令的情况下,根据轮胎的滑动比来估计施加在轮胎上的纵向力; 基于估计的纵向力估计值确定轮胎驱动电动机的转矩限制值; 以及当给出所述旋转指令以将轮胎的转速改变时,将所述转矩限制值应用于所述轮胎驱动电动机的转矩限制。 通过这样的结构,在进行滑动比的同时进行轮胎试验的情况下,能够对轮胎驱动电动机施加过大的过载而进行试验。
