도 2를 참조하면, 본 발명에 의한 전기식 주차 브레이크를 구비한 건설중장비는 운전자의 실수에 의해 주차 브레이크 해제 스위치(2)가 작동됨은 물론 쉬프트 레버(3)가 조작되더라도 운전자가 가속 페달을 밟아 엔진회전수가 증가된 것으로 감지되지 않은 경우에는 주차 브레이크의 잠김 상태를 유지하도록 엔진회전수 감지수단(5)을 제공함으로써 전술된 바와 같은 문제점을 미연에 방지하도록 구성되어 있다. 여기서, 엔진회전수 감지수단(5)은 운전자가 가속 페달을 밟음을 감지할 수 있도록 가속 페달 또는 엔진회전수를 감지하기 용이한 부분에 설치된 센서로서, 트랜스미션 콘트롤러(1)와 전기적으로 연결되어 있다.Referring to FIG. 2, in the construction equipment including the electric parking brake according to the present invention, the driver brakes the engine even when the shift lever 3 is operated as well as the parking brake release switch 2 is operated by a driver's mistake. In the case where the rotation speed is not detected to be increased, the engine speed detection means 5 is provided to maintain the locked state of the parking brake. Here, the engine speed detection means (5) is a sensor installed in the portion that is easy to detect the accelerator pedal or the engine speed so that the driver can detect the stepping on the accelerator pedal, it is electrically connected to the transmission controller (1). .

이를 좀 더 상세히 설명하면, 본 발명에 의한 엔진회전수 감지수단(5)이 설치된 전기식 주차 브레이크 시스템은 운전자의 주행 의도에 의해 주차 브레이크 해제 스위치(2)가 작동되고(S11) 가속 페달이 밟혀졌음을 엔진회전수 감지수단(5)에 의해 감지되면(S12) 이러한 정보들은(S11;S12)은 각기 전기적으로 연결된 트랜스미션 콘트롤러(1)에 입력되어 주차 브레이크가 해제된다. 따라서, 이렇게 주차 브레이크가 해제된 후 운전자는 쉬프트 레버(3)를 조작하면(S2) 트랜스미션 콘트롤러(1)에 의해 트랜스미션 솔레노이드(4)가 작동되어 건설중장비는 운전자의 의도에 따라 전진 또는 후진하게 된다. 여기서, 단계 S11과 S12는 반드시 순차적으로 수행될 필요는 없으며 순차적으로 또는 역행적으로 수행되어도 무관하나 반드시 두 단계 S11과 S12가 수행되어야 한다.In more detail, in the electric parking brake system provided with the engine speed detecting means 5 according to the present invention, the parking brake release switch 2 is operated by the driver's driving intention (S11) and the accelerator pedal is pressed. Is detected by the engine speed detecting means 5 (S12), the information (S11; S12) is input to the transmission controller 1 electrically connected to each other, and the parking brake is released. Therefore, after the parking brake is released, the driver operates the shift lever 3 (S2) to operate the transmission solenoid 4 by the transmission controller 1 so that the construction equipment is moved forward or backward according to the driver's intention. . Here, steps S11 and S12 are not necessarily performed sequentially but may be performed sequentially or backward, but two steps S11 and S12 must be performed.

특히, 본 발명의 방법은 운전자가 주차 브레이크 해제 스위치(3)를 작동함과 아울러 순차적으로 가속 페달을 실수로 밟았다 하더라도 이러한 상태가 시동이 걸려진 상태가 아니라 단지 전원이 인가된 상태라면 엔진회전수 감지수단(5)은 가속 페달이 밟혀졌다하더라도 엔진은 정지된 상태임으로 주차 브레이크는 해제되지 않도록 구성되어 있다.In particular, the method of the present invention, even if the driver operates the parking brake release switch 3 and sequentially presses the accelerator pedal by mistake, if the engine speed is only a state in which the power is applied instead of the starting state, The sensing means 5 is configured such that the parking brake is not released because the engine is stopped even if the accelerator pedal is stepped on.

이상에서 살펴본 바와 같이 본 발명의 방법에 의하면, 운전자의 정상적인 주행 의도없이 실수에 의해 주차 브레이크 해제 스위치가 작동된 경우에도 주차 브레이크의 잠김 상태를 유지토록 함으로써, 건설중장비가 경사진 곳과 같이 위험한 장소에 주차된 경우에 주차 브레이크의 해제에 의한 건설중장비의 움직임에 의해 발생되던 대인 또는 대차 추돌사고를 미연에 방지할 수 있는 효과가 있다. 또한, 본 발명의 방법은 주차 브레이크 해제 스위치의 작동과 가속 페달이 밟혀져 엔진회전수가 증가되는 것이 모두 감지되어야 주차 브레이크가 해제되도록 구성함으로써 운전자의 주행 의도가 확실한 경우에만 주차 브레이크가 해제되어 건설중장비가 주행되도록 한 것이다.As described above, according to the method of the present invention, even if the parking brake release switch is operated by mistake without the driver's normal driving intention, the parking brake is kept locked, so that a dangerous place such as a place where the heavy construction equipment is inclined. When parked in the parking lot, there is an effect that can prevent inadvertent person or truck collision caused by the movement of heavy construction equipment by the release of the parking brake. In addition, the method of the present invention is configured so that the parking brake is released only when both the operation of the parking brake release switch and the accelerator pedal are stepped and the engine speed is detected to be released, so that the parking brake is released only when the driver's driving intention is clear. Is to drive.
