Abstract
A method for optimizing vehicle steer-by-wire characteristics, includes collecting steer-by-wire steering system data for multiple predetermined data segments. Multiple driving quality objective indices are determined for each segment. A trend line is prepared based on the multiple predetermined data segments using a first algorithm, a second algorithm and a third algorithm, each assigned to one of the driving quality objective indices. Values obtained from the first algorithm, the second algorithm and the third algorithm are superimposed to create a net desired incremental change in damping, steering ratio and base assist. A steering calibration modification command is generated in real-time using the incremental change in damping, steering ratio and base assist.
