The development of Safety control system [ABS / VDC] can be reduced development cost and time by Simulation Techniques which can pre-verify various requirements and design specifications at the initial development’s stage. Simulation techniques can be classified into MILs, SILs, and HILs. HILs is a technology designed to be developed at the same level as real systems by combining it with real hardware to improve the inaccuracies of pure simulation techniques such as MILs and SILs. However, in the case of commercial vehicles which are having many wheels and axes. So there are limitations in establishing HILs environment for verifying and developing commercial vehicle’s Safety control systems. In this study, we propose a development method to convert actual pneumatic brake system into RT [Real time] model through the Analytical Model. Also, we propose RT-based EILs [ECU In-the Loop Simulation] which provides equivalent environment to HILs by replacing actual hardware with RT model.

A modeling technique is proposed for dynamic simulations of swash plate axial piston pump. A dynamic model of Axial piston pump is used to SimulationX software. SimulationX, multi-domain simulation and modeling tool for the design, analysis, and optimization of complex systems. This papers modeling of a hydralic axial piston pump with SimulationX and complete model of an axial piston plate pump with 9 elements combined with 3D-animation. The MBS(Multi Body System) part of the model is more for animation even the piston masses are physical models. Only the piston block is an animation body. This model is to show the hydraulic network. There are no centrifugal effects at pistons or barrel included. SimulationX modeling physical systems based on libraries of basic elements is the key for rapid prototyping and modeling. The purpose of this papers is to give a framework to SimulationX users to model an axial piston pump. Some of the results obtained are perhaps different from a real device and now the work of the component designer to adjust the different parameters and the variable edges, the design parameters of the piston, swash plate control parts and so forth.
