Abstract :
Electric Power Steering (EPS) systems have many merits over traditional hydraulic power steering systems in fuel economy, variable assist capabilities and favorable road feeling by virtue of adjustment assist characteristic with adopting assist motor in replacement of hydraulic pump. This paper aims at modeling the mechanical parts, the assist motor and electronic control unit by bond graph technique and simulating system dynamic performance regarding vehicle maneuverability and stability and driver´s steering feel by Matlab/Simulink. The simulation results provide that the bond graph EPS model can reflect stability and dynamic steering characteristic in effect.
