    摘要： The present application relates to a braking method and a braking system. The braking method of the present application may be performed by an electro-mechanical braking system including at least one axle control unit and a plurality of electro-mechanical braking devices provided at ends of wheels and driven by motors to apply friction braking forces to the wheels. The electro-mechanical braking devices are controlled by at least one axle control unit to switch between a state in which no friction braking is applied and a state in which friction braking is applied in response to a braking requirement. The braking method includes: setting a brake clearance between a brake pad and a brake disc to an initial value; determining whether there is a braking requirement; determining wherther regenerative braking is performed; and in response to the performing of regenerative braking, setting the brake clearance to a preset value, wherein the preset value is smaller than the initial value. The brake clearance is reduced before friction braking is required, the respond time to the friction braking requirement is shortened, so that the switch between friction braking and regenerative braking is smoother, thereby the pause and transition during the switch between brakings is effectively reduced.

    摘要： A rail vehicle brake unit (200) contains a brake actuator (120), at least one pressing member (211), a gear assembly (220), an electric motor (230) and a backup power unit (123). The brake actuator (120) receives a brake command (cmdB) and produces an electric brake-force signal (BF) to the electric motor (230) that, in turn, acts on the gear assembly (220) to cause the at least one pressing member (211) to attain a specified position in relation to a rotatable member (110) mechanically linked to at least one wheel (105) of a rail vehicle so as to apply a braking force thereto. During operation of the rail vehicle, the backup power unit (123) receives electric power (W) from a power line (140) in the rail vehicle and accumulates the received electric power (W). In case of an electric power failure (PF) in the electric power (W) received in the brake actuator (120), the backup power unit (123) provides the accumulated electric power to control circuitry in the brake actuator (120) and the electric motor (230).

    摘要： A controller (26) for an electromechanical brake actuator (28) (EBA) is provided. EBA (28) has a motor (20) driven in response to a motor drive signal generated by controller (20). Controller (26) includes a velocity limiter (108) and a current limiter (130). Velocity limiter (108) limits a velocity command in response to a measured braking force signal output (50). Limited velocity command (120) has a positive velocity limit boundary defined between a positive maximum velocity limit setpoint (W2) and a positive minimum velocity limit setpoint (W1) and a negative velocity limit boundary (W3) defined between a negative maximum velocity limit setpoint (W4) and a negative minimum velocity limit setpoint. Current limiter (130) limits a current command in response to the measured braking force signal output (50). Limited current command (132) has a positive current limit boundary defined between a positive maximum current limit setpoint (I2) and a positive minimum current limit setpoint (I1) and a negative current boundary defined between a negative maximum current limit setpoint (13) and a negative minimum current limit setpoint (14).

    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). The controller (9) includes: a motor angular velocity control section (40) configured to control an angular velocity of the electric motor (2); differential value calculator (44) configured to calculate a differential value of a braking command value; and angular-velocity-corresponding-to-differential-value limiting section (41) configured to limit the angular velocity of the electric motor (2) by the motor angular velocity control section (40) such that the less the differential value calculated by the differential value calculator (44) is, the lower the angular velocity of the electric motor (2) is.
