| Zusammenfassung: | The problem addressed by the invention is that of making the handling of a tire model for the control of a test run on a test stand (11) easier and more flexible and thus more practical. This problem is solved in that at least a longitudinal velocity (vx) of a tire (1) is calculated in a first simulation unit (30) by means of a first simulation model (33) and the longitudinal velocity (vx) is transmitted to a second simulation unit (35), a longitudinal force (Fx) and/or a rolling resistance torque (My) of the tire (1) is calculated on the basis of the longitudinal velocity (vx) in the second simulation (35) by means of a second simulation model (36), and a dynamometer setpoint value (SD) for a drive control unit (34) of a loading machine (17) of the test stand (11) is determined by means of the longitudinal force (Fx) and/or the rolling resistance torque (My).
为了更简单、灵活且因此实用地操纵轮胎模型来控制试验台上的测试运行，规定：在第模拟单元(30)中利用第模拟模型(33)计算轮胎(1)的至少个纵向速度(v)并且将该纵向速度(v)传输给第二模拟单元(35)，在第二模拟单元(35)中借助纵向速度(v)利用第二模拟模型(36)计算轮胎(1)的纵向力(F)和/或 |
