<p>PROBLEM TO BE SOLVED: To improve braking accuracy in an electric brake device wherein a pressing member is advanced by driving of an electric motor to press a friction member on a rotor, thereby actuating a brake. SOLUTION: A detected pressing power of a pressing power sensor 88 in a non-actuating state of a brake and in a case where a pressurizing rod 24 is moved backward by an set amount and more, or moved backward to a back limit from that state, is set as a reference value. In this state, a practice pressing power is certainly in a 0 state, so that the detected pressing power is equal to an offset amount of 0 point. The offset amount is used as a reference value, and by controlling an electric motor 16 on the basis of the reference value and the detected pressing power, controlling accuracy of braking power can be improved better than by controlling the electric motor on the basis of the detected pressing power.</p> |
