Research on Electro-Hydraulic Hybrid Brake System Combined with ABS

Article Preview

Abstract:

A novel electro-hydraulic brake system configuration was designed by adding a hydraulic control module on conventional brake system with ABS, which achieves independent hydraulic braking force control for each wheel. With the purpose of improving energy recovery efficiency, a braking force distribution algorithm based on ECE regulations and motor external characteristics was proposed. Then further simulation verification was made to demonstrate its availability by using ADVISOR. Finally, a key aspect specific to independent hydraulic braking force control, a bilinear interpolation algorithm was defined and a hardware test was carried out. The results verify the feasibility and effectiveness of this algorithm.
