Modeling and analysis of regenerative braking system for electric vehicle based on AMESim

This paper presents a parametric and modularized method in modeling the hydraulic components of the regenerative braking system, through which the newly built model has gained noticeable improvement in precision. The strategy for the exiting of the regenerative braking is optimized. The simulations are conducted in the co-simulation platform between AMESim and MATLAB/Simulink at the initial vehicle speed of 40 Km/h. The simulation results show that the newly built hydraulic model can describe the process of pressure increase and decrease precisely. Meanwhile the motor cooperates with the hydraulic braking system well throughout the whole braking procedure. The maximum jerk exerted on the vehicle is decreased from 2.69 m/s³ to 0.59 m/s³ during the exiting of regenerative braking, and the regeneration efficiency is increased to 76.18%.
