<p>In this paper, we propose an optimization method to evaluate the actual fuel efficiency of Power-Split(PS) type hybrid vehicles(HEV) using Dynamic Programming(DP) considering dynamic characteristics of engine and motor speed changes. Frequent speed changes in HEV’s engines and motors cause energy loss and adversely affect drivability. Therefore, by adding the number of cases of gear ratios to the DP-based optimization, the engine and motor behave similarly to the actual physical situation with no penalty. In addition, the optimization is ensured by reflecting errors in the problem of dividing the grid in DP. The simulator developed through this optimization method is useful for setting target values for improving the fuel efficiency of PS type HEV.</p>
