Disclosed is an integrated electronic hydraulic brake which can reduce the pressure pulsation generated when a pump works. According to an embodiment of the present invention, the integrated electronic hydraulic brake comprises: an integrated hydraulic power control unit which comprises a master cylinder for generating hydraulic pressure by the pedaling power of a brake pedal, a reservoir combined with the master cylinder to store oil, an accumulator for storing oil to control the pressure, and a hydraulic pressure control valve and a pressure reducing valve connected between the accumulator and a wheel cylinder installed on each wheel to control the pressure conveyed from the accumulator to the wheel cylinder; and a power source unit which comprises a pump for taking in oil from the reservoir through a hydraulic pressure pipe for forming a pressure in the accumulator to discharge the oil to the accumulator, and a motor for driving the pump. The integrated hydraulic power control unit additionally comprises a pulsation reducing chamber placed on a flow path connected in between the accumulator and the hydraulic pressure control valve to have a space with a greater volume than that of the flow path. |
