The proportional electro-hydraulic brake (PEHB)  includes a body with two halves, four proportional solenoid valves (replacing traditional four sets of the inlet and outlet valves), two accumulators, an electric motor and a hydraulic pump. When ABS mode is activated, PEHB can master the slip ratio to an assigned value (prior EHB products can only avoid the slip ratio over a limit), then exerting a stable and optimal braking force for the specific wheel.

The actuator of a proportional Electro-Hydraulic Brake System (PEHB) is a safety device providing the independent braking forces to four individual wheels to slow down the car. It includes four hydraulic control valves (replacing traditional four sets of the inlet and outlet valves) to controls the fluid pressure through the force balance mechanism. PEHB actuator, with both maximum braking force and stability, is a novel and original invention which received two patents  (US8531259B2-Proportional Electromagnet / US8814280B2-Proportionally Controllable Hydraulic Brake System) in the United States, and five (I320372/I363011/I317330/I320374/I474350) in Taiwan respectively.
