Control, Modeling and Simulation on A Novel Regenerative Brake System of Electric Vehicle

Regenerative braking is a vital technology to reduce the electricity consumption in a variety of electric vehicles. A considerable improvement on energy economy is achieved by the electric motor running as a generator during vehicle deceleration. As an essential part of the regenerative braking system (RBS), regenerative hydraulic braking system (RHBS) acts an important role in regenerative braking. In this paper, a novel RHBS system with a cooperative control strategy is proposed to meet the requirement of both energy recovery and dynamic braking performance. The cooperative control strategy is composed of a hierarchical control structure in RBS and RHBS. The regenerative braking system is modeled and simulated in MATLAB/Simulink and AMESim platform. A specified ECE (Economic Commission for Europe) driving cycle is utilized as the simulation scenario. Simulation results show that the proposed RHBS has an expected hydraulic pressure control proficiency and the RBS with cooperative control strategy is effective in improving energy economy and dynamic performance.
