HARDWARE-IN-THE-LOOP SIMULATION AND ITS APPLICATIONS IN AUTOMOTIVE EMBEDDED SYSTEM

Abstract

To meet challenges of future automotive embedded applications, vehicle manufacturers are adopting ECU architectures because they are more reliable, more efficient, add less weight to a vehicle, and can offer more functionality. The increased complexity inherent in these systems works against business pressures to reduce time-to-market and development cost. Fortunately, HIL simulation has proven to be a practical solution to these diverging challenges. The main concept behind hardware-in-the-loop simulation is that of including a part of the real hardware in the simulation loop during system development. Rather than testing the control algorithm on a purely mathematical model of the system, one can use real hardware (if available) in the simulation loop.
