Abstract

Abstract: Shift control directly impacts the power and cost of electric vehicles.It is one of the important development directions for intelligent automobiles. Owing to the differences in design and development approaches of various manufacturers, there is a considerable difference in the dynamic and economic shift rules. This study focuses on the Shifeng D102 model.The dirving style is obtained by detecting the acceleration of the vehicle, and the fuzzy control algorithm is introduced into the shift rule to achieve the coordination of vehicle dynamics and cost. Finally, the Simulink model is used for performing simulation analysis under cyclic conditions, and the fuzzy control algorithm shift rule is considered to reduce power consumption while with respect to the vehicle′s dynamic performance, which results in an enhanced comprehensive performance, rendering it suitable for most working conditions.

Key words: electric automated mechanical transmission, shift rule, fuzzy control, simulation analysis
