Hardware in the loop/human in the loop, H2IL testing is done by connecting the simulator hardware and software to an actual test system with real components attached and performing testing by driving on simulated roads. This simulation in turn generates the necessary loads, accelerations and displacements to drive the components as if they were in the actually vehicle on the actual road. Then the feedback of the components is fed back into the simulator to allow the driver to get the feel or drivability of the components. The H2IL- testing is a very viable form of validating design of vehicles and vehicle components. This is a process that has been employed for many years in the aerospace industry and will prove to be the way of the future for the automotive industry. As proving ground and track time becomes more costly and as shortened program timescales drive parallel development to become the norm, the need for H2IL will become more interesting and important to the OEMs and Tier Suppliers, not to mention race teams.
