Abstract
An electric brake including: a brake mechanism configured to transmit a thrust force generated through drive of an electric motor to a piston, the piston being configured to move brake pads to be pressed against a disc rotor; a thrust force sensor configured to detect the thrust force transmitted to the piston; and an ECU for rear electric brake configured to control, based on a detection value obtained by the thrust force sensor, the drive of the electric motor in accordance with a brake command. The ECU for rear electric brake is configured to learn, as a reference point of a piston thrust force, a detection value obtained by the thrust force sensor when the electric motor is driven to move the piston in a direction for pressing the piston against the disc rotor in a range in which the brake pads are not in contact with the disc rotor.
