In the precedent work, we established a mathematical modeling of powertrain dynamics for the construction vehicle. The target system has automotive layshaft transmission that consists of many shafts and rotating members. To simulate shifting mechanism with good precision, it is very important to identify the parameters of internal powertrain elements. Furthermore, so is it in point of the performance prediction , simulation analysis and control application. In this paper, we discuss sensitivity analysis to examine the effect of parameter variations on vehicle turbine speed. And we accomplish the identification of the parameters of the powertraine elements by conducting several experiments. In some cases, we made an actual device for measuring inertia moment of the rotating members. For the estimation of the other parameters, we conducted shifting experiments and used least-square-method based on the turbine speed error between simulation and experiment. We then confm good estimation accuracy by proving that the estimated parameters can also be applied to another experimental condition.
