A study on the characteristics of automotive brake pedal force

자동차 제동장치의 답력특성에 관한 연구

In this study, the function of a hydraulic brake system with a vacuum booster is systematically analyzed according to the mutual relations which follow : - the brake pedal force vs. booster cylinder input force - the booster output force vs. master cylinder input force - the hydraulic line pressure vs. braking deceleration. A computer program is developed based on the theory which is able to predict and analyze the pedal force characteristics at the beginning of the initial stage of brake system design. Analytical results show good agreement with the experimental vehicle test.
