Abstract:
1. An electric brake device, comprising: a brake pad configured to apply a pressure against a rotation face of a brake rotor in a direction perpendicular to the rotation face; a linear converter configured to convert a driving force of a motor into a linear movement to transmit the linear movement to the brake pad; an axial force sensor, provided at the linear converter, and configured to detect a brake axial force obtained by the pressure by the brake pad; and a controller configured to perform a speed reduction control which is an operation target, and configured to obtain a speed from a wheel speed sensor; wherein the controller is configured to perform the speed reduction control based on the brake axial force in a case where the speed is higher than zero and lower than a predetermined speed, and to perform the speed reduction control based on the speed obtained from the wheel speed sensor in a case where the speed is higher than or equal to the predetermined speed.
