HiL simulation and controller prototyping of EV/HEV systems using multi-core xEV Real time Simulator

Abstract

The real-time simulation is an efficient mechanism in EV/HEV power train analysis and testing of Electronic Control Unit (ECU). This enables ECU software development, calibration and testing in closed loop without the actual vehicle. Using Hardware in Loop (HiL) simulation, the development of control software can be carried out before the real hardware implementation of the vehicle. This method reduces development cost by reducing development time, risk factor and eliminating the use of expensive destructive test systems. This paper discusses HiL Simulation and Rapid Controller Prototyping of EV/HEV Systems by making use of a multi-core xEV real time Simulator. xEV Real time Simulator is a cost effective yet powerful solution for real time simulation which utilizes MATLAB for offline desktop simulation and C code generation. By making use of advancement in processor platforms such as multi-core processors, the real time capability of simulator is enhanced.
