A complete novel software for MDPS for simulation and analysis is proposed for the steering engineers. This software MSAS which can provide the functionality MDPS Simulation, Analysis & Synthesis is basically based on steering system model, vehicle model and control logic. As the suppliers provide the control logic as a black box this software can be able to use any type of black box logic or white box control logic which can be developed by logic designers. Also this software will be synthesized with suppliers’ s-function control logic and RMDPS together.
