Abstract
An electromechanical brake device and a method of controlling the same provide the electromechanical brake device capable of estimating motor characteristics, and the method capable of controlling the electromechanical brake device by estimating motor characteristics. The electromechanical brake device includes a reaction force generating mechanism which is installed between a piston and one side of a caliper housing, generates reaction force applied against straight moving force of the piston, which moves backward in an axial direction, in a direction in which a braking operation is released, and applies reaction force to the piston; a sensor which detects a motor operating state; and a controller which estimates a motor torque constant that represents a correlation between motor electric current and motor rotational torque, based on motor operating state information detected by the sensor when an operation of the motor is controlled.
