Braking Evaluation of Integrated Electronic Hydraulic Brake System Equipped in Electric Vehicle

摘要

Brake-by-wire system is becoming the vital actuating component in electrified vehicles and autonomous vehicles. This paper proposes a newly designed electronic hydraulic brake control system integrated with the featured specialties including regenerative and anti-lock braking control. The running principle behind the electronic hydraulic brake control system is studied in detail to illustrate the different usages when adapted to various braking conditions. To coordinate with the electromechanical system, a combined braking control strategy is presented. A complete electric vehicle simulation system is built on basis of MATLAB/Simulink, AMESim and CarSim, and the simulation is carried out in two typical scenarios of regenerative and anti-lock braking process. The simulation results show the proposed integrated electronic hydraulic brake system has the effectiveness in the performance evaluation of energy recovery and emergency braking conditions.
