| Abstract: | An optimal control scheme of the power distribution for a parallel HEV is investigated.The optimum solution is obtained using dynamic programming method with the performance indicators for dynamic programming emphatically analyzed.Among them the performance indicator with the objective of minimum power loss is proposed for this investigation.In addition,the physical relationship between the fuel consumption and the change in SOC of battery is established.The results of simulation show that the dynamic programming effectively enhances the fuel economy of HEV and the effectiveness is more remarkable with the 'power loss' performance indicator. |
