We have conducted various tests and vehicle dynamics simulations using 1/10 model vehicles. In order to simulate the vehicle motion of the 1/10 model vehicle, firstly, it is necessary to build a numerical model system consists of springs and dampers. The frequency response is obtained from the vibration test of the model vehicle, and the parameters in the predetermined model are searched and modified to be determined as those of a numerical model. The brute-force search within a specific range is conducted using known parameters as clues in parameter identification. In more detail, some optimization methods, such as the least square method, are also used. However, in many cases, the validity of the parameters of the model is empirically evaluated by comparing with known specifications. Thus, a more quantitative method in parameter identification is desired. Therefore, we first investigate the behavior of parameters when they are optimized for the up-down system, which is relatively easy to identify empirically.
