为提高纯电动汽车的续驶里程，降低能量消耗率，本文中针对其燃油经济性进行了换挡规律的仿真。首先制定出两参数静态经济性换挡规律；然后利用动态规划算法找出在ECE循环工况下的最优挡位，并据此对所制定的静态经济性换挡规律进行修正，得到最终经济性换挡规律曲线；最后，在UDDS行驶工况下，建立了纯电动汽车耗电量模型，对修正前后的换挡规律进行仿真。结果表明，修正后的换挡规律能有效地降低纯电动汽车的能量消耗率。

In order to extend the driving mileage and reduce the energy consumption of electric vehicle, its shift schedule is simulated aiming at fuel economy in this paper. Firstly, a static economical shift schedule with two-parameter control is worked out. Then by using dynamic programming algorithm, the optimal gear under ECE driv-ing cycles is found, and based on which the static economical shift schedule is revised with the final economical shift schedule curve obtained. Finally an electricity consumption model for electric vehicle is set up, and a simulation on the shift schedule before and after revision is conducted with UDDC driving cycles. The results show that the revised shift schedule can effectively reduce the energy consumption of electric vehicle.
