Abstract

Abstract: Dual-driving powertrain system of pure electric vehicle has two power sources and the main function of power control strategy for finished vehicle is: power distribution in order to control operating condition of all components for the powertrain system according to operating characteristics of powertrain system and components of finished vehicle as well as driving status data of vehicles. In overall consideration of the impacts of efficiency of all components for powertrain system and system efficiency in different operating patterns on efficiency of finished vehicle, control strategy of pattern division and power distribution is based on optimum efficiency of driving system in order to guarantee basic performance of finished vehicle and increase driving range of finished vehicle. MATLAB/Simulink simulation analysis software is used to establish simulation platform for powertrain system of pure electric vehicle with two driving force and to carry out simulation verification for control strategy of finished vehicle. The results show that all power components can be put into synergetic operation and vehicles will have higher performance, energy saving effects as well as efficient and reasonable control with the control strategy which has been developed.
