The overall aim of this research is the development of a force-feedback model for the steering system of super lightweight Steer-By-Wire (SBW) vehicles. The immediate goals are to explore the role of force-feedback (a.k.a. steering feel) transmitted from the front wheels to the handwheel in road vehicles and, connectedly, to emulate and enhance the steering feel in SBW systems. More specifically, the goals are to (a) perform various driving experiments in an SBW test rig to collect input/output data from/to steering system and vehicle dynamics, (b) investigate the role of force-feedback in super lightweight vehicles so that a mathematical model for generating a proper steering feel in an SBW system can be developed, (c) investigate the cooperation of other information, which is obtained from the vehicle dynamics, with the designed steering feel model with regard to driving performance and thus enhance the steering feel, and (d) develop a steering feel model specific to a driver, through a learning algorithm, for more comfortable steering.
