Abstract
An electric brake apparatus can positively prevent a brake motor from being excessively rotated in a reverse direction in which a braking force is cancelled. A determination is made as to whether or not the brake motor is excessively driven in the reverse direction. An operation of the brake motor is stopped when the brake motor is determined to be excessively driven in the reverse direction. Accordingly, a member of the electric brake apparatus moved by the brake motor is prevented from being excessively moved beyond a predetermined position. Thus, a part of the electric brake apparatus is prevented from being damaged due to an excessive movement of the member moved by the brake motor.
Claims7
An electric brake apparatus for generating a braking force by driving a brake motor in a predetermined direction, the braking force being canceled by driving the brake motor in a reverse direction opposite to the predetermined direction, said electric brake apparatus comprising:
- excessive rotation determining means for determining whether or not said brake motor is excessively driven in the reverse direction;
- and
- motor stopping means for stopping an operation of said brake motor when said brake motor is determined to be excessively driven in the reverse direction.
