Research and Verification of Cooperative Regenerative Braking Function Based on Electrical Brake Booster System

Abstract

The regenerative braking technology is an effective means to increase the mileage of electric vehicles and reduce the energy consumption per hundred kilometers and is a key issue in the research of electric vehicles. With the development trend of intelligent and electrified vehicles, electrical brake booster system is undoubtedly the best choice for automotive boost brake. This article proposes a control scheme of cooperative regenerative braking function based on a domestic home appliance electrical brake booster system. The program refers to the functional framework and communication interface of the VDA360 standard. The main controller is a vehicle control unit. The motor system and the electrical brake booster system act as actuators. At the same time, based on the wheel hub test and real vehicle road test, the control scheme was verified by multiple conditions. The results show that the cooperative regenerative braking function greatly improves the vehicle energy recovery rate, and the development of this function lays the groundwork and foundation for the subsequent development of intelligent driving functions and active braking functions.
