    Abstract
  • In order to decrease the variation amplitude of wheel cylinder pressure for electro-hydraulic braking system(EHB), the pressure variation rate was represented by the stable pressure variation value, and the variation law in the working range was investigated. The formula to calculate the stable pressure variation value was deduced, some experiments were carried out to measure the stable pressure variation values under different initial pressures and duty cycles. Calculation result shows that the curves of the rates have inflection points according to the initial pressures. At the left side of every inflection point, the pressure variation rate increases with the increase of initial pressure. While at the right side, the rate decreases. The inflection points at different duty cycles appear at the nearly same cylinder pressure. As the inflection point is caused by piston motivation, it is named as piston motivation's end pressure. In the system, it is about 2.9 MPa. The relationship between the pressure rate and the duty cycle is approximate linear in working pressure range.
