Brake control device

A brake control device applied to a vehicle comprising:

• a hydraulic brake device that generates a hydraulic braking force by pressing a braking member with hydraulic pressure toward a member-to-be-braked that rotates integrally with a wheel;
• and
• an electric brake device that generates an electric braking force by pressing the braking member by driving a motor toward the member-to-be-braked, wherein
• a propeller shaft that transmits the driving force of the motor to the braking member toward the member-to-be-braked,
• a controller that controls the electric brake device is provided, and
• the controller executes a positional control that the propeller shaft is moved closer to the member-to-be-braked by controlling the motor when a predetermined condition is satisfied than a position when the predetermined condition is not satisfied,
• wherein the controller moves the braking member by a second predetermined distance in a direction toward the member-to-be-braked using the hydraulic pressure generated by the hydraulic brake device before executing the positional control.

• wherein when the predetermined condition is satisfied, the controller executes the positional control by driving the motor so as to move the propeller shaft in the direction toward the member-to-be-braked, stopping the drive of the motor when a current value exceeds a predetermined first threshold after an inrush current flows, and thereafter, driving the motor to move the propeller shaft in the direction opposite to the member-to-be-braked, and stopping the drive of the motor when the current value falls below a predetermined second threshold.
