EBD Step-up Control Research during Cornering Braking for Electric Vehicles on High Energy Regenerative Braking/Driving Integrated System

Abstract

This paper sets up high energy regenerative braking and driving integrated system for electric vehicle and its dynamic model based on the wheel hub motor and friction brake integrated into electric vehicle braking system. Bend EBD hierarchical strategy of control is put forward, which is based on ABS system. Establish dynamic simulation system of electric vehicle integrated brake system and EBD control simulation system based on the Matlab /Simulink. Based on CheryA3 model car, the wheel hub motor drive system replaces the power system; carry out simulation and analyze the control performance of the integrated braking system during cornering braking. The results show that the bend EBD control performance of high energy regenerative braking/driving integrated system for electric vehicle is good, which has a high braking energy recovery rate, braking efficiency and braking stability.
