POWERFUL AND ADAPTIVE STEERING BEHAVIOR AND REAL-TIME FEELING FOR STEER-BY-WIRE VEHICLES

摘要

A method for optimizing vehicle steer-by-wire characteristics, comprising collecting steer-by-wire steering system data for a plurality of predetermined data segments. For each segment, several destination indices are defined for the ride quality. A trend line is prepared based on the plurality of predetermined data segments using a first algorithm, a second algorithm, and a third algorithm, each associated with one of the ride quality destination indices. The values obtained from the first algorithm, the second algorithm and the third algorithm are superimposed to produce a desired incremental net change in attenuation, steering ratio and base assistance. A change command for the steering calibration is generated in real time using the incremental change of damping, steering ratio and basic assistance.
