Hardware-in-the-Loop Simulation of Pure Electric Vehicle Control System

Hardware-in-the-loop (HIL) testing and simulation is increasingly being used in the test and design of vehicle control system. Utilizing Matlab/Simulink with dSPACE, a hardware-in-the-loop simulation platform for the control system of pure electric vehicle is built. HIL simulation of vehicle control units, especially the vehicle management system, are carried out based on CAN bus communication. A control-monitor interface for HIL testing is set up using ControlDesk to observe and measure input/output signals. In order to examine the reliability of HIL platform, primary simulation models built through Matlab/Simulink are replaced by real components, including electric motor and Ni-H battery, with true sensors from practical vehicles. Result confirms a good stability of the HIL platform, which can be flexible to allow extension and reconfiguration.
