Abstract
This research aimed to inquire the steering feeling performance according to the steering system and the EPS Logic using the steering model and to propose the improvement direction of steering feeling performance for our vehicle through comparative analysis with a competitor vehicle with an excellent steering feel. Firstly we define objective indices of steering feeling using subjective-objective correlation study about voice of customers and reverse engineering about competitors. Second, we propose straight forward method to decide the parameter which is related to steering feeling for obtaining the characteristics of reference vehicle. A simulation model can make that procedure efficient. Therefore we implement the process using the multi-body simulation model that is validated by test result.
