Based on brake control model in ADVISOR,a new model in which the braking share of every braking force varies on the braking deceleration was built from the dynamical standpoint for using ADVISOR to analyze recovery capacity of braking energy of the regenerative braking system which satisfies the braking stability in the electric vehicle (EV) and hybrid electric vehicle (HEV).The simulation results show that the model developed can effectively extend the application scope of ADVISOR and bring convenience to evaluate the regenerative braking system in EV and HEV.
