Tilt Type Steering Column의 Tilt Angle에 따른 Steering Ratio Variation에 관한 연구

There are many vehicles produced with steering height adjustment system for customer convenience these day. The trend have moved from luxury vehicle to small vehicle as a option. In small vehicle case, If it needs same level of height change of steering wheel it could be required much steering column angle change compare to large vehicle due to package or size limitation and it cause bad effect on steering performance by steering geometry change. So even if tilt type steering column gives convenience to customer but a lot of steering column angle change makes bad results about vehicle’s handling performance target and concept that we want to make goal. This study’s purpose is finding a relation about handling performance and steering geometry change by tilt angle of steering column. First we should know steering ratio variation according to steering column angle change. And then we can study steering sensitivity change by steering ratio variation on handling side. Finally we are able to know what is previous CAE activity before making a decision for steering tilt angle with this results.
