摘要： Provided are an electric-powered actuator and an electric braking device which are capable of reliably operating a reverse-input holding mechanism and can achieve cost savings. The electric-powered actuator includes a control device (2) including: a motor angle estimation unit (22a), and a reverse-input holding control section (24) having a function of engaging an engaging part (15) with an engaged part by controlling a solenoid (16) to set the reverse-input holding mechanism (7) into a reverse-input holding state while the electric-powered actuator (DA) is applying a load and a function of, from the reverse-input holding state, disengaging the engaging part (15) from the engaged part to set the reverse-input holding mechanism (7) into a reverse-input holding release state. The reverse-input holding control section (24) includes an engagement intermediate control function section (24a) configured to control the estimated rotation angle such that the engaged part and the engaging part (15) come into a predetermined positional relation within a certain period of time, when the engaging part (15) is brought into engagement with the engaged part and when the engaging part (15) is brought out of engagement with the engaged part.

摘要： A highly reliable vehicle brake system that includes an electric brake and achieves redundancy at low cost is provided.
A vehicle brake system (1) includes a first control device (10) and a second control device (11) that respectively include a master controller (30), a first sub-controller (40), and a second sub-controller (41) that are connected to one another. Each of the master controller (30), the first sub-controller (40), and the second sub-controller (41) includes a braking force calculation unit that calculates braking force of electric brakes (16a to 16d), and a determination unit that compares braking force calculation results of the controllers to determine whether itself is normal. The determination unit includes an output block section that blocks, when the determination unit determines that any one of the controllers is not normal, an output of the controller that is determined to be not normal.

摘要： The electric brake device includes a control device (2) for performing follow-up control such that a braking force estimated value estimated by a braking force estimator (26) follows a given braking force command value. The control device (2) includes an angle-sensorless control function section (20) for determining a phase of phase current of an electric motor (4) irrespective of an actual angle of the electric motor (4) and controlling the electric motor (4) to have a current value that is based on the determined phase of the phase current. The angle-sensorless control function section (20) includes a current phase determination section (25b) for determining a current phase that is the phase of the phase current of the electric motor (4) on the basis of a deviation between the braking force command value and the braking force estimated value.

摘要： Provided is an electric brake device that can suppress increase in power consumption and that can improve responsiveness. This electric brake device includes: a brake rotor; a brake pad; an electric motor (2); a linear motion mechanism configured to convert a rotary motion of the electric motor (2) into a linear motion so as to be transmitted to the brake pad; a controller (9) to control the electric motor (2); and a brake command (40) device to send a braking force command to the controller (9). The controller (9) includes: an emergency braking detector (41) to detect an emergency braking request; a steady state controller (46) to perform braking in a steady state; and a flux weakening controller (42) to perform flux weakening control. The flux weakening control is performed when the emergency braking detector (41) detects an emergency braking request.
