Research on intelligence torque control for the electrical variable transmission used in hybrid electrical vehicle

Abstract

This paper introduced a new kind electrical variable transmission used in hybrid electrical vehicle, then analysed the flux coupling status of electrical variable transmission with the methods of equivalent flux path and ansoft simulation. For the structure which had flux isolation ring in the outer rotor, an new torque control strategy based on fuzzy logic control was proposed for electrical variable transmission. The model of hybrid elcetrical vehicle with electrical variable transmission was completed using Matlab/Simulink, and the simulation results demonstrate the feasibility of the proposed method, and it can be adopted as a new theory and method for the study of hybrid electric vehicle.
