Advances in Desktop Hardware-in-the-Loop Simulation

Hardware-in-the-Loop Simulation allows ECUs to be tested in a simulated environment in closed loop. Engines, vehicles, and other components the ECU normally controls are replaced by high-fidelity models executed on a real-time computer system. This paper shows that today's hardware/software technology makes comprehensive and powerful low-cost desktop simulators feasible. It is also shown that it is now possible to use the same tools for Hardware-in-the-Loop Simulation that have been used in the control development.
