Abstract

The present disclosure provides an electric brake apparatus having an electro-mechanical brake disposed in each wheel of a vehicle and configured to perform braking control of the vehicle, the electric brake apparatus including a friction pad configured to press a brake disc of each wheel; a pressing unit configured to generate a clamping force by pressing the friction pad against the brake disc; a motor configured to generate a rotational force and transmit the rotational force to the pressing unit; a current sensor mounted on the electro-mechanical brake to measure current flowing through the motor; a motor rotation angle sensor mounted on the electro-mechanical brake to detect a rotation angle of the motor and output a rotation angle signal; and a main controller configured to calculate an actual motor current based on a voltage signal input from the current sensor, calculate an actual stroke using the rotation angle signal input from the motor rotation angle sensor, determine whether or not the friction pad is worn using the actual motor current and the actual stroke, calculate an amount of friction pad wear when determination is made that the friction pad is worn, calculate a target stroke using the amount of friction pad wear, and perform the braking control of the vehicle based on the target stroke.
