Abstract
An electric brake device is provided which is capable of early detecting presence/absence of abnormality in the brake device during the traveling of a vehicle in the absence of the operation of a brake application device. A controller includes an abnormality detecting operation controller which operates the electric motor according to a predetermined condition during the traveling of the vehicle in the absence of the operation of the brake application device. The device further includes an abnormality detector which obtains a measured value of a predetermined item related to the vehicle when the electric motor is operated by the abnormality detecting operation controller, and compares the measured value with an estimated value or a set value to detect presence/absence of abnormality in the brake device.
