Hardware-in-the-loop simulation and its application in electric vehicle development

In order to make full use of the advantages of hardware-in-the-loop (HIL) simulation and improve the quality of electric vehicle (EV) development, the concept and the development process of HIL simulation were introduced, the present study situation of EV HIL simulation at home and abroad was analyzed. By means of summing up the research achievements and shortages, the direction for further improvement was pointed out. What was found from the research is that, only by means of adopting modular design and CAN bus technology the HIL simulation technology can be applied flexibly. It would be better to use multi-body dynamics theory to establish more accurate simulation models of the EV components and adopt some advanced control strategies to speed up system response and reduce simulation errors. Moreover, more systematic match theory of EV HIL simulation platform needs to be established, the quality of hardware used in the simulation also needs to be improved.
