Electro-mechanical brake apparatus and controlling method thereof

Abstract

A method for controlling an electro-mechanical brake apparatus is disclosed. According to an embodiment of the present disclosure, provided is a method for controlling an electro-mechanical brake apparatus, including: a step of determining whether a state of a central controller is a functional failure state; a step of receiving, by a plurality of wheel controllers, wheel speed information of each wheel measured from a plurality of wheel speed sensors when it is determined that the state of the central controller is the functional failure state; a step of selectively comparing a wheel acceleration of each wheel determined based on the received wheel speed information with a plurality of wheel variable conditions; a step of determining a sign of a wheel jerk based on the wheel acceleration; a step of calculating a slope of a target clamping force based on the results of comparison with the wheel acceleration and the plurality of wheel variable conditions and a sign determination result of the wheel jerk; and a step of performing emergency braking of the vehicle by increasing or decreasing an emergency braking force based on the calculated slope of the target clamping force.
