The present invention relates to a control method of an electro-mechanical brake and, more specifically, provides a control method of an electro-mechanical brake, which diffuses maximum current weighted at an electrical angle by forcibly moving the electrical angle with an adjacent electrical angle when a vehicle is stopped by operating an electro-mechanical brake, and an electrical angle on each phase of a three-phase motor is placed on a maximum current point. The control method of an electro-mechanical brake comprises: a first step of operating a brake to stop a vehicle and generating a target pressure value of the brake; a second step of calculating an electrical angle of a three-phase motor and preparing movement of the electrical angle when the vehicle stops; a third step of checking errors of requested current and pressure; a fourth step of setting a range of the electrical angle when the current and the pressure are normal; and a fifth step of forcibly moving an actual position of the electrical angle to an adjacent electrical angle.
본 발명은 전자식 브레이크에 관한 것으로, 더욱 상세하게는 전자식 브레이크 작동하여 차량이 정차되었을 때, 3상 모터 각 상의 전기각이 최고 전류 지점에 위치하면 인접 전기각으로 전기각을 강제 이동시켜, 전기각에 편중되는 최고 전류를 분산시키는 전자식 브레이크의 제어방법을 제공한다.
