Abstract：Inorder to explore the working characteristics the pressure boosting valves and pressure reducing valves the One Box Electro-Hydraulic Braking System （EHB），multi-field-coupled modeling and simulating methods pressure boosting valvesand pressure reducing valves were proposed，and results were verified by innovative testing bench.The structures and working principals pressure boosting valves and pressure reducing valves were introduced.Each physicalcharacteristic pressure boosting valves and pressure reducing valves were precisely modeled.Multi-field coupling simulations，including electromagnetic field，flowfield，andmotionfield，andexperimentalverificationsforthepressureboostingvalvewereconducted. Simulationsand experimental verifications wereperformed forthe pressure reducing valve，including electric circuit，electromagneticfield，and motionfield.Theresultsshowthatthesimulationeror theflowrate pressure boostingvalve is lower than 1.5mL/s ，the open delay response error pressure reducingvalve is smaller than 1.3ms ，and the close delay response error smaller than 0.3ms ，indicating that the proposed simulation method hasa highaccuracy，and providing a guidance for the control thevalves.
