Abstract: Disclosed is a method for controlling a valve in an electronic hydraulic pressure control system, capable of effectively controlling the valve such that differential pressure between a master cylinder and a wheel cylinder is constantly maintained. The method includes the steps of measuring pressure of the master cylinder, measuring pressure of the wheel cylinder, and controlling on/off operation of the valve based on a current value obtained according to the differential pressure between the master cylinder and the wheel cylinder.

Abstract: Disclosed are an electronic hydraulic pressure control system and a control method thereof, capable of detecting an error in differential pressure between a master cylinder and a wheel cylinder. The control method includes the steps of acquiring pressure of a master cylinder and pedal pressure according to a stroke distance of a pedal, detecting a time point at which the pressure of the master cylinder and the pedal pressure reach predetermined reference pressure, and determining that an error occurs if the time point exceeds a predetermined reference time point.
