发明名称 Electric Brake Device
摘要 An electric brake device that allows reduction of generation of an operating noise without impairing a function of a brake, is provided. The electric brake device includes a brake rotor, a brake pad, an electric motor (2), a linear motion mechanism, and a controller (9). Vehicle speed detector (44) configured to detect a vehicle speed, is provided, and the controller (9) includes: a motor angular velocity control section (40) configured to control an angular velocity of the electric motor (2); and angular-velocity-corresponding-to-vehicle-speed limiting section (41) configured to limit, in a no-load state where a clearance is between the brake pad and the brake rotor, the angular velocity by the motor angular velocity control section (40) such that the lower the vehicle speed detected by the vehicle speed detector (44) is, the lower the angular velocity of the electric motor (2) in the no-load state is.

主权项 1. An electric brake device comprising: a brake rotor; a brake pad; an electric motor; a linear motion mechanism configured to convert a rotary motion of the electric motor into a linear motion to transmit the linear motion to the brake pad; and a controller configured to control the electric motor, the electric brake device comprising a vehicle speed detector configured to detect a vehicle speed, wherein the controller includes: a motor angular velocity control section configured to control an angular velocity of the electric motor; and an angular-velocity-corresponding-to-vehicle-speed limiting section configured to limit the angular velocity of the electric motor according to the vehicle speed detected by the vehicle speed detector.
