Abstract
A function modularization control system is established for the vehicle with a new full hybrid power-train structure consisting of two electric motors and a set of coupling device. Control strategies based on ICE optimized operation schedule are utilized to improve the power-train efficiency and to reduce fuel consumption. With the development tool of MATLAB/SIMULINK and special debugging tool, a prototype of multi-energy control unit is completed. Over 5,000 kilometers road test of the vehicle shows the feasibility and reliability. And the performance of the vehicle has been improved.
