Dynamic model of steer-by-wire system for driver handwheel feedback

Abstract

International audienceRecent advances towards steer-by-wire technology have promised significant improvements in vehicle handling performance and safety. This technology inspired from aeronautics, consists in replacing the traditional mechanical linkages and/or hydraulic power assist with electrical equivalents. This paper describes the adopted approach for development of a new dynamic model of a Steer-by-wire system with hydraulic assistance in the case of stopped vehicle. The aim is to establish dynamic equations of the forces and torques exchanged between handwheel and the front wheels during steering operations. Some simulation results are provided. The proposed model will be experimented using a prototype equipped with handwheel feedback system

Optimal Design of PMSA for SBW Application

“…Permanent Magnet Synchronous Actuators (PMSA) have become more attractive because they respond well to new technology requirements [1]. The renewed interest for these machines is due, in large part, to their excellent dynamic characteristics, low loss and their high specific torque, making them better suited to industrial applications requiring electrical drive control position or speed [2].…”
