Regenerative Braking System Pressure Control Calculation Based on ABS Hydraulic Model

Abstract:

The main objective of this work is to present a methodology for development of regenerative braking system hydraulic model that can be used to estimate the master cylinder pressure, master cylinder travel position, normal open valve fluid flow, normal open valve cross-sectional area, normal close valve fluid flow, normal close valve cross-sectional area, accumulator fluid flow and brake caliper fluid flow. According to the above hydraulic model calculation, the cooperation between regenerative braking system generator and ABS hydraulic braking control will be smooth and the arbitration strategy can be designed. Through the simple hydraulic model, the entire brake circuit of ABS can be derived easily.
