摘要： PROBLEM TO BE SOLVED: To generate a test input value matching with a tire deflection of net zero.
SOLUTION: A contact loss composition 12 for correcting a tracing parameter in a control loop is used to avoid an inaccurate load to a testing vehicle to control a simulator in a predetermined effective road profile for a road surface. A tire deflection obtained during measuring of calculating the profile of a vehicle tire is influenced only by a freely dynamic response of a suspension of a profile motion. An area in which the tire profile is not a function of a road input is detected and used for indicating it. A tire model is first created for the vehicle. The vehicle is mounted at a simulator, and assembling of control signals is generated in the control loop. The control signal drives the simulator so that a response generated in the simulator coincides with a predetermined effective tire profile. A decision of assembling the control signals includes a selection of a combined tracing response from a generated output for displaying the tire brought into contact with the road surface and a deflection output of the tire for displaying the tire losing contact with the road surface.
