The study of braking feedback includes investigating how to distribute the motor regenerative braking force and traditional friction braking force, and taking the customer’feelings when braking into account on the premise of good braking efficiency.This paper will analyze the braking energy feedback,including six sections.In the first section,based on the introduction of topic background andresearch meanings,the electric automobile development is discussed and the significance of feedback control to electric automobile performance is presented. The second section mainly discusses the fundamental principles of feedback of braking energy recycle and major factors affecting the braking feedback efficiency. According to the research aim,I determines driving system structure of model vehicle and structure schematic of braking feedback system,analyzes the distribution principle of braking force.The third section analyzes the mathematic relation and conducts modeling of key components of braking feedback system under the ADVISOR condition.In the fourth section,the BEV simulation parameters are set up,different operating modes of braking are selected and the simulation of this dynamic co-simulating model is conducted.I analy a series of emulated data and curves from the simulation results.The fifth section summarizes the whole work,analyzes the shortcomings and future directions,and discusses the issues considered in next step.
