Title:
ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/022148
Kind Code:
A1
Abstract:
Provided is an electric brake device with which a switch power supply can be reliably charged and caused to operate rapidly when a brake operation next occurs, and with which no-load noise and vibration can be improved. The electric brake device is provided with a switch means (21) such as a half bridge circuit for controlling a state of connection between a coil end of an electric motor (6) and a power supply device (3). The electric brake device is provided with a switch power supply (22) having an electric power storing function, comprising a capacitor or the like for switching the switch means (21). The electric brake device is provided with a charging means (24) such as a charging circuit which causes the switch means (22) to store electric power, in a predetermined switching pattern of the switch means (21). The electric brake device is provided with a brake standby function unit (16) with which, when it has been determined that a transition to a brake released state is complete, at least the electric motor (6) in a stationary state is not driven spontaneously, and the switch means (21) is maintained in a predetermined switching pattern capable of being caused to store electric power in the switch means (22) by means of the charging means (24).
