METHOD FOR CONTROLLING VALVE IN ELECTRONIC HYDRAULIC PRESSURE CONTROL SYSTEM
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.
1 . A method for controlling a valve in an electronic hydraulic pressure control system, the method comprising:
measuring pressure of a master cylinder;
measuring pressure of a wheel cylinder; and
controlling on/off operation of the valve based on a current value obtained according to differential pressure between the master cylinder and the wheel cylinder.
2 . The method as claimed in claim 1 , wherein the valve is controlled such that the valve is open according to an open model when the differential pressure between the master cylinder and the wheel cylinder is higher than predetermined reference differential pressure by a predetermined value or more.
3 . The method as claimed in claim 1 , wherein the valve is controlled such that the valve is closed according to a dose model when the differential pressure between the master cylinder and the wheel cylinder is lower than predetermined reference differential pressure by a predetermined value or more.
4 . The method as claimed in claim 2 , wherein the open model represents a current value at a time point at which the valve is open according to the differential pressure between the master cylinder and the wheel cylinder.
5 . The method as claimed in claim 3 , wherein the close model represents a current value at a time point at which the valve is dosed according to the differential pressure between the master cylinder and the wheel cylinder.
