Provided is an electric brake capable of accurately estimating the brake pad temperature and securing a sufficient braking force and response. An electric brake has a disc rotor rotating with a wheel, an actuator for rectilinearly actuating a piston in the axial direction of the disc rotor by using an electric motor, a drive controller for controlling the drive of the actuator, a brake pad pressed by the piston to give a frictional resistance to the disc rotor in the direction of rotation, and a braking start position detector for detecting a braking start position of the piston where the disc rotor is brought into contact with the brake pad. The drive controller stores the braking start position detected by the braking start position detector as the maximum braking start position. When the braking start position shifts in the pressing force-increasing direction, the drive controller updates the value stored as the maximum braking-start position.

Dynamic alignment monitoring system for on-vehicle disk brake lathe

A dynamic alignment monitoring system allows an operator to monitor the misalignment of an on-vehicle disk brake lathe with respect to a vehicle axis about which the disk to be machined rotates, and can allow the operator to discontinue further alignment when appropriate in order to speed the overall time of the alignment process. The system processes signals from an angular rate sensor and a tachometer, using a scaling routine to derive a LRO value corresponding to the LRO of the disk which would result from machining in the current alignment condition. A representation of the derived LRO value is displayed to the operator. An operator override can allow the operator to discontinue further alignment adjustments when an acceptable alignment condition is indicated. The system can aid the operator by also presenting a representation of an acceptable LRO value for the particular vehicle being serviced.

Proposed is an elevator control device in which an unbalance torque estimation unit configured to estimate an unbalance torque in a motor is implemented in accordance with such a new finding that the unbalance torque can be estimated based on a first time period from an output change of a brake state command signal for switching an operation state of a brake from a braking state to a releasing state to a time when the motor starts a rotating operation along with release of the brake, and on a positive or negative sign of a velocity signal obtained when the motor starts rotation. As a result, as compared to the related art, a smaller calculation load can be achieved. Further, the elevator control device can have a sufficient responsiveness for suppressing an influence of the unbalance torque.
