Zusammenfassung:	The present invention relates to a technique for an electric park brake (EPB) and, more particularly, to a detection device and a detection method for detecting the number of revolutions of a sensorless EPB motor 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 the number of revolutions of a sensorless motor, including: 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 includes a ripple measuring unit for receiving an output signal of the motor and measuring a ripple of the motor.
