S. Alles et al., THE HARDWARE DESIGN OF A REAL-TIME HITL FOR TRACTION ASSIST SIMULATION, IEEE transactions on vehicular technology, 44(3), 1995, pp. 668-682
A computer simulation methodology which simulates a vehicle in real-ti
me is presented. The vehicle has been divided into a number of subsyst
ems, and each subsystem is modeled separately, Along with the models,
the hardware components of several control units were linked together
to provide a generic real-time Hardware-in-the-Loop (HITL) vehicle sim
ulation especially suited with third-party propriety hardware. Such a
model provides the capability to verify analytical and experimental da
ta and adjust the hardware/software of certain vehicle components on t
he test bench, It also provides powerful, complex, and dynamic real-ti
me simulations yet, because it is portable, it reduces onboard vehicle
testing time, which makes it adaptable to include different types of
vehicles, and also makes it cost effective. This paper outlines the ma
jor features of the simulation models, showing a typical application f
or Traction Assist (TA) development. The simulation model was verified
for a TA event by taking measurements from an onboard computer while
the vehicle was driven on various types of road surfaces. The results
obtained experimentally corresponded well with those obtained through
simulation.
