Electro-mechanical brake control method and apparatus

Abstract

An electro-mechanical brake control method and apparatus are disclosed. An embodiment of the present disclosure provides a method of controlling an electro-mechanical brake(EMB), using a controller, wherein the electro-mechanical brake includes a current sensor and a motor rotation angle sensor, the method comprising: receiving a target clamping force generated based on a pedal stroke value; generating a clamping force feedback in response to the target clamping force and calculating a force error by comparing the clamping force feedback with the target clamping force; measuring an stroke of a piston using the motor rotation angle sensor; controlling the motor so that the stroke of the piston is located at a contact point by applying a current to the motor; and controlling the electro-mechanical brake for reducing noise and shock generated in the electro-mechanical brake by variably limiting a maximum or minimum amount of current applied to the motor based on the stroke of the piston.
