Abstract
An electric brake apparatus includes an electronic control unit (ECU) configured to move a power piston to cause a braking hydraulic pressure to be generated in a master cylinder by controlling an electric motor of an electric actuator based on an operation on a brake pedal (an input member position). A characteristic update processing portion of the ECU is configured to update, based on an operation amount of the brake pedal, characteristic data indicating a relationship between a hydraulic value transmitted from the ECU via a vehicle data bus and a movement amount of the power piston controlled based on the input member position, and store the updated characteristic data. The ECU is configured to control the electric actuator based on the updated characteristic data when an automatic brake instruction is input.
