Vehicle pull is one of the most important problem at the initial stage of vehicle development. It is generally known that the vehicle pull is a phenomenon occurred by the residual force and moment. To minimized vehicle pull in this paper introduces the analysis method of vehicle pull simulation which makes it possible to consider matching factors between a vehicle and tires using design of experiments. Therefore, it has analyzed the correlation between factors using ADAMS/CAR S/W including PAC2002 Tire model.

The vehicle ride comfort is one of the most important performances in the automotive industry. The vehicle ride comfort is rated as SAE subjective assessment by professional test driver. But, subjective assessment is lack of objectivity. So recently objective assessment has been used in researching in the areas of the vehicle ride comfort. In this study, a passenger car is driven at several tires, vehicle speeds, road profiles. And objective assessment method for the vehicle ride comfort test is constructed. First, the triaxial accelerometers are mounted on the knuckle, floor, seat, seat-back and are measured by twelve accelerations. And the measured accelerations express one ride comfort value according to Human Vibration of ISO 2631-1 and BS6841. Correlations are determined between objective ride comfort value and subjective rating.
