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 driving 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.
