Study on Electro-Hydraulic Parallel Brake System using HILS

Regenerative brake system (RBS) has been one of the most important systems which can improve vehicle economy efficiency along with the development of clean energy vehicle (CEV), such as HEV (hybrid energy vehicle) and FCV (fuel cell vehicle). This paper provides a simple and reliable Electro-Hydraulic Parallel Brake System (EHPBS) based on the conventional vehicle brake system. This EHPBS can implement parallel distribution strategy between regenerative brake force and the hydraulic brake force thereby achieves kinetic energy regeneration. Because of the difficulty and the danger of brake system experimentation, this paper tests the EHPBS in HILS (Hardware-In-the-Loop Simulation) environment, and the experiment data prove the system to be available and effective.
