Method, program product and system for testing tires of vehicles for quantifying tire force and torque transient responses

摘要

A method of testing a tire of a vehicle, the method comprising the steps of: Generating a first test condition including a first slip angle of the tire and a load of the tire with a tire load; Obtaining a first data set relating to the performance of the tire under the first condition; Setting a tire load of zero after obtaining the first set of data; Generating a second condition including a second slip angle of the tire and a load of the tire with a tire load, the tire being loaded with the tire load after setting the second slip angle; Obtaining a second set of data regarding the performance of the tire under the second condition; and Determining a relationship between a force of the tire and a moment of the tire using the first data set and the second data set, wherein the step of generating the first condition comprises the step of allowing the forward movement of the tire; and wherein the step of generating the second condition comprises the steps of: Stopping the forward movement of the tire; Steering the tire; and Resuming the forward movement of the tire.
