Force-Feedback System Design for the Steer-By-Wire: Optimisation and Performance Evaluation

Current state of art power assisted steering systems used in vehicles are hydro-mechanical type systems, i.e. the steering column motion is transmitted and amplified by the main hydraulic circuit by hydro-mechanical means. Electrical versions of such steering systems are gaining success and are beginning to be implanted in most vehicles. Next step is the so-called by-wire concept. This paper presents a steer-by-wire system which we designed and tested on a vehicle (Peugeot 307). The focus is set on the system optimisation in order to increase the so-called steering feel. The simulation results and the driving tests conducted on the prototype vehicle are very promising, compared to such existing systems
