차량 쏠림 민감도 분석을 이용한 쏠림 개선에 관한 연구

Vehicle pull is one of the most important problem on the vehicle quality from customers. To understand the vehicle pull, this paper describes vehicle pull phenomenon by considering causing factors of conicity and PRAT, vehicle factors of wheel alignment, and the external environment factor of road slope and weight. Those factors must be analyzed to improve the vehicle pull tendency. Therefore, by using Pull sensitivity analysis, vehicle pull simulation which makes it possible to consider the effect of passenger and road slope, PRAT, conicity and wheel alignment, is applied to evaluate and Steering Wheel Torque.
