Electrically powered brake device

An electric brake device comprising:

• a brake rotor;
• a friction member;
• a friction member operator configured to bring the friction member into contact with the brake rotor;
• an electric motor configured to drive the friction member operator;
• a rotation angle estimator configured to estimate a motor rotation angle of the electric motor;
• a braking force estimator configured to estimate a braking force;
• and
• a control device configured to control the braking force by use of the electric motor so as to achieve a target braking force,
• wherein the braking force estimator includes:
• a direct estimator configured to convert, into an estimated braking force, output of a braking force sensor which detects a load or displacement corresponding amount acting on one of the friction member, the friction member operator, and a member supporting the friction member or the friction member operator;
• and
• an indirect estimator configured to estimate the braking force on the basis of information other than the output of the braking force sensor, and
• wherein a range below a predetermined threshold value in which the braking force is only estimated by the direct estimator is a specified low-braking-force range, and in a specified high-braking-force range above the predetermined threshold value and beyond the specified low-braking-force range, estimation of the braking force is only performed by the indirect estimator.
