Document Type and Number:
WIPO Patent Application WO/2017/142300
Kind Code:
A1
Abstract:
The present invention relates to an invention for an electric park brake (EPB) and, more particularly, to a detection device and a detection method for detecting a number of revolutions of an EPB motor without a sensor other than a conventional EPB motor equipped with a built-in sensor. According to an embodiment of the present invention, provided is a detection device for detecting a number of revolutions of a sensorless motor, comprising: an actuator driving motor used to set and release a parking brake of an EPB system; an electronic control module for controlling the motor; a vehicle battery for supplying power to the motor and the electronic control module; and a main processing unit for receiving an output signal of the electronic control module and estimating the number of revolutions of the motor, wherein the electronic control module further comprises a ripple measuring unit for receiving the output signal of the motor and measuring a ripple of the motor.
