Control strategy simulation of hybrid electric vehicle

Abstract

A good hybrid electric vehicle control strategy can make the predetermined performance of hybrid vehicles to reach the optimal value of good, or else the good fuel saving effect is unable to obtain, so paper analyzed the demand torque and torque distribution of the hybrid electric vehicle at first, then designed a logic threshold control strategy of vehicles, and determined the control parameters and the needed to be optimized parameters of the logic threshold; after that verified the validity of the model which is established of the CRUISE and MATLAB/SIMULINK; lastly based on the NYCC condition to carry on the simulation analysis of the control strategy, the results show that in the case of NYCC the proposed control strategy can be saving fuel less23.9% than the original vehicle's 23.9%, improve the fuel saving effect.
