Abstract:
According to at least one aspect, the present disclosure provides a method of controlling an electro-hydraulic brake including an electronic brake-force distribution (EBD) control function, the method comprising: an emergency braking determination operation of determining whether emergency braking is required for a vehicle; a motor control operation of controlling a current flowing in a motor connected to a main master cylinder to increase hydraulic pressure supplied to wheel brakes when it is determined that the emergency braking is required; a rear wheel inlet valve closing operation of closing an inlet valve connected to a rear wheel brake for a predetermined time so that a pressure of the rear wheel brake is not increased earlier than a pressure of a front wheel brake; a closed time period calculation operation of calculating a time during which the inlet valve is maintained in a closed state; and a rear wheel inlet valve opening operation of determining whether a time during which the inlet valve is closed exceeds a closed time period (t), maintaining the inlet valve in the closed state until the time reaches the closed time period (t), and opening the inlet valve when the time exceeds the closed time period (t).
