Abstract: For the proposed electro-hydraulic brake system based on an integrated master cylinder, the pedal force transmission paths were analyzed under normal and failure operation modes. The pedal feeling and its influence factors were investigated. A pedal feeling simulator was designed with cluster springs, and simplified models under different operation modes were established using AMESim. The parameters, such as the piston damping coefficient, which affect the pedal force-stroke curve, the pedal rod return spring preload force, solenoid valve flow area and booster ratio, were studied by simulation. Bench test results show that the brake pedal characteristics could meet the design requirements, and the pedal force-stroke hysteresis losses are 11.5% for normal mode and 15.3% for failure mode, respectively.

Key words: vehicle engineering, electro-hydraulic brake system, pedal feel, hysteresis loss
