Brake device

A brake device, comprising:

• braking members configured to clamp a braked member, which is rotated together with a wheel, to apply a braking force to a vehicle;
• a piston configured to move the braking members toward the braked member or in a direction away from the braked member;
• an electric motor;
• a linearly movable member configured to move linearly through driving of the electric motor and come into contact with the piston so as to move the piston;
• a control unit configured to perform application control for applying the braking force to the vehicle through feeding of power to the electric motor and release control for releasing the braking force to the vehicle;
• a current monitoring unit configured to monitor a motor current caused to flow though the electric motor;
• and
• a wheel-velocity sensor,
• wherein, in the presence of a non-zero signal output from the wheel-velocity sensor, the control unit includes a stepwise increase control unit configured to, when start of contact between the braking members and the braked member caused by continuously energizing the electric motor is detected based on the motor current monitored by the current monitoring unit, increase in a stepwise manner a clamping force applied by the braking members to the braked member by performing the actuating and stopping of power to the electric motor for a set predetermined number of times.

A brake device, comprising:

• braking members configured to press a braked member, which is rotated together with a wheel, to apply a braking force to a vehicle;
• a control unit configured to perform application control for applying the braking force to the vehicle through feeding of power to an electric actuator and release control for releasing the braking force to the vehicle;
• and
• a wheel-velocity sensor,
• wherein the brake device is configured to press the braking members toward the braked member by the electric actuator so as to retain a pressing force of the braking members, and
• wherein, in the presence of a non-zero signal output from the wheel-velocity sensor, the control unit continuously energizes the electric actuator, until start of contact between the braking members and the braked member is detected, and then performs stepwise increase control for increasing in a stepwise manner the pressing force applied by the braking members to the braked member by through repeated actuating and stopping of power to the electric actuator.
