Electric Differential System Based on Dual-closed- loop Slip Rate Control

摘要：

In this paper, one 7-Degree-Of-Freedom (DOF) dynamic model of four-wheel drive electric vehicle is proposed and its effectiveness in reflecting dynamic features of an electric vehicle is verified by Matlab/Simulink. A novel Electric Differential (ED) system with both speed and torque loops is then presented, after extensive review and analysis of the currently available solutions. Both theoretical analysis and computer simulations demonstrate that in the presented electric differential system, slip rates are controlled in an optimal extent and the possibility of hazardous situation brought by speed difference being out of control of is greatly reduced.
