Title:

ELECTRIC PARKING BRAKE CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/009730

Kind Code:

A1

Abstract:

The present invention discloses an electric parking brake control device capable of accurately determining operation of an electric actuator. The electric parking brake control device is capable of performing an application process for controlling the electric actuator to move in the direction in which a friction member is pressed against a rotation body that rotates integrally with a wheel and a release process for controlling the electric actuator to move in the direction in which the friction member is moved away from the rotation body. Even upon receiving (time t12) a new operation request for operating the electric actuator during a period (time t1 to t5) from the start of the application process or the release process to the completion of the process, the electric parking brake control device does not change the operation of the electric actuator on the basis of the operation request.
