A quantitative description of a system or process by one or more mathematical equations is termed as Mathematical Model or simply Model. The Model is used to study the process behaviour with respect to the variables and parameters of interest using a digital computer. For a given system, the parameters are constants that characterize the system. If a system is described by a mathematical equation, a coefficient in that equation is a parameter. The variables are the attributes having arbitrary values. Some of the variables in a system are subject to the control and are referred as control variables.

Apart from the influences on the system responses, parameters are also critical factors to impact the performances of the system dynamics control and observation [27]. Specifically, the vehicle system parameter estimation has received considerable attentions. Wenzel [28] proposed dual filter structure for lateral vehicle model. Parameters of sprung mass, yaw inertia and distance from the front axle to the C.G. were estimated by one filter, and system observation was obtained from another. Rozyn [29] used modal analysis techniques to estimate the sprung mass inertial parameters including mass, moments of inertia and C.G. position. It can be found that different types of system parameters were estimated in the aforementioned literature. Nevertheless, what parameters are more important for vehicle control and observation was less investigated.
