“…Currently there are a few researches for EPS modeling using bond-graph theory. The document [3] proposed the theory into steering system modeling without assist motor; In the document [4,5], EPS model is built without considering road random inputs and the energy coupling part is still built on the basis of classical mechanics theory, in addition, the assist characteristic and driver control model are neglected which exert an influence on the system.…”

As a tool of modeling the system of multiple energy, bond-graph theory is applied to the modeling for electric power steering system which is electromechanical hybrid. Bond graph models for C type, P type and R type of EPS dynamic system are built respectively. The CH7140 type of car equipped with C type EPS is taken as a prototype and its maneuverable performance is simulated under typical working conditions. A PID control method with time delay transfer function is adopted to imitate the driver’s operation. Steering maneuverability test of the CH7140 car is conducted. The simulation result is consistent with the test result. It is shown that the bond-graph model of EPS is rational, and simulation model derived from bond-graph is effective which can be applied to EPS and full vehicle steering maneuverability simulation research.

“…Steering system parameters were analysed and optimized in a steering system model (3) with front suspensions. Bond Graph technique was adopted by Vijayakumar and Barak (4) to simulate steering systems. Sharp and Granger (5) developed a model to investigate the main influences of steering torque at parking speeds.…”

A comprehensive mathematical model of a typical hydraulic power steering system equipped with variable ratio rack and pinion gear is developed. The steering system's dynamic characteristics are investigated and its forced vibrations are compared with those obtained from a counterpart system with a constant ratio rack and pinion gear. The modeling details of the mechanism subsystem, hydraulic supply lines subsystem and the rotary spool valve subsystem are provided and included in the integrated steering system model. The numerical simulations are conducted to investigate the dynamics of the nonlinear parametric steering system. From the comparison between simulated results and the experimental ones, it is shown that the model accurately integrates the boost characteristics of the rotary spool valve which is the key component of hydraulic power steering system. The variable ratio rack-pinion gear behaviors significantly differently from its constant ratio counterpart does. It significantly affects not only the system natural frequencies but also reduces vibrations under constant rate and ramp torque steering inputs. The developed steering model produces valid predictions of the system's behavior and therfore could assist engineers in the design and analysis of integrated steering systems.
