Abstract:
Steer-By-Wire (SBW) system offers the possibility to set freely the relation between the tire steer angle with the drivers steer input (steering gain), and also the steering reactive torque with the drivers input, respectively. This paper concerns about the study of effect of steering gain and steering reactive torque on the drivers feeling for a SBW vehicle. Outline of the SBW system and SBW vehicle are presented. Experiment results show that the steering reactive torque and steering gain have a big effect on drivers feeling, which was evaluated from the drivers mental and physical workload; and furthermore, optimum steering gain and steering reactive torque is dependant on drivers characteristics and driving task.
