이하에서는 본 발명에 따른 전자식 주차브레이크 시스템의 작용에 대하여 설명하기로 한다.Hereinafter will be described the operation of the electronic parking brake system according to the present invention.

우선, 운전자가 누름스위치(230)를 누르지 않은 경우, 제 1 전원선(A)과 제 1 신호선(C)는 단선되고 제 2 전원선(B)와 제 1 신호선(C)는 도통됨으로써, 제 1 전원선(A)으로부터 입력되는 전압은 신호저항(R3)에 의해 감압되어 제 1 신호선(C)으로 출력된다. 이에 따라, 제어부(100)는 제 1 신호선(C)으로부터 입력되는 전압을 메모리(130)에 저장하고 전자식 주차브레이크 시스템의 해제로 인식하며, 램프스위치(220)는 오프되어 작동상태램프(210)는 소등된다. 이로써, 운전자는 전자식 주차브레이크 시스템이 미작동임을 인식할 수 있게 된다.First, when the driver does not press the push switch 230, the first power line A and the first signal line C are disconnected, and the second power line B and the first signal line C are conducted so that The voltage input from the first power supply line A is decompressed by the signal resistance R3 and output to the first signal line C. FIG. Accordingly, the control unit 100 stores the voltage input from the first signal line C in the memory 130 and recognizes the release of the electronic parking brake system, and the lamp switch 220 is turned off to operate the operation lamp 210. Is turned off. This allows the driver to recognize that the electronic parking brake system is inoperative.

반면에, 운전자가 누름스위치(230)을 누르는 경우, 제 1 전원선(A)와 제 1 신호선(C)은 도통되고 제 2 전원선(B)과 제 1 신호선(C)은 단선됨으로써, 제 1 전원선(A)으로부터 입력되는 전압은 바로 제 1 신호선(C)으로 출력되며 램프스위치(220)는 제 1 누름스위치(231)의 오프단(231b)로부터 신호를 입력받아 온된다. 이에 따라, 제어부(100)는 제 1 신호선(C)으로부터 입력되는 전압을 메모리(130)에 저장된 전압과의 차이를 확인하여 전자식 주차브레이크 시스템의 적용으로 인식하며, 램프스위치(220)는 온되어 작동상태램프(210)는 점등된다. 이로써, 운전자는 전자식 주차브레이크 시스템이 작동 중임을 인식할 수 있게 된다. 한편, 이때, 제어부(100)는 모터구동부(120)에 제어신호를 공급하여 차량이 주차되도록 한다.On the other hand, when the driver presses the push switch 230, the first power line (A) and the first signal line (C) is conducted and the second power line (B) and the first signal line (C) are disconnected, The voltage input from the first power line A is directly output to the first signal line C, and the lamp switch 220 is turned on by receiving a signal from the off terminal 231b of the first push switch 231. Accordingly, the controller 100 recognizes the difference between the voltage input from the first signal line C and the voltage stored in the memory 130 as an application of the electronic parking brake system, and the lamp switch 220 is turned on. The operation state lamp 210 is turned on. This allows the driver to recognize that the electronic parking brake system is in operation. In this case, the controller 100 supplies a control signal to the motor driving unit 120 so that the vehicle is parked.
