Abstract
Starting from an energetic model of a traditional steering system, this paper proposes three different kinds of architecture for the implementation of a steer-by-wire system on off-highway vehicles. The force feedback and the rack hydraulic control cannot be ideal systems and this affects the overall vehicle dynamics, moreover the effects on the vehicle behavior depends on the chosen architecture. The hardware independent approach proposed in the paper drives the definition of the control requirements on the steering wheel control and on the rack control subsystems and it allows to appreciate the effects of the architecture on the implementation of a steer-by-wire system.Pubblicazioni consigliate
