Research on regenerative braking control strategy of hybrid electric vehicle

For the shortage of the original strategy of braking force distribution in hybrid electric vehicle (HEV) simulation software ADVISOR, a new model which the braking share of every braking force varies on the change of load was built from the standpoint of dynamics, based on the original regenerative braking control model. The model is simulated by ADVISOR software in HAFEI sample car and the simulation results show that the effect of energy recovery in new control strategy is superior to the original one, emissions of harmful gases are reduced and the motor efficiency is improved significantly. The braking force distribution method is also in accordance with ECE regulation. So the control strategy proposed in this paper is proved to be reasonable and effective. This kind of model expands the scope of the ADVISOR simulation effectively and facilitates the study of hybrid electric vehicle.
