Field of the Invention The present invention relates to an engine speed override control device, and more particularly, to an engine speed override control device capable of providing an excellent response characteristic to a driver, providing a constant feeling of operation and preventing an operation shock.
도 1은 휠 타입 건설기계, 상세하게는 휠 타입 굴삭기에 있어, 종래의 엔진 회전수 오버라이드 제어장치의 구성을 개략적으로 보여주는 도면이다. 1 is a view schematically showing the configuration of a conventional engine speed override control device in a wheel type construction machine, in particular a wheel type excavator.
도시한 바와 같이, 도 1의 엔진 회전수 오버라이드 제어장치는, 회전수설정 입력부(34), 회전수가속 입력부, 제어부(11) 및 엔진(17)을 포함한다. As shown, the engine speed override control apparatus of FIG. 1 includes a rotation speed setting input unit 34, a rotation speed acceleration input unit, a control unit 11, and an engine 17.
회전수설정 입력부(34)는 운전자로부터 엔진(17)의 회전수를 임의의 회전수로 설정하는 회전수설정 입력을 받는다. The rotation speed setting input unit 34 receives a rotation speed setting input for setting the rotation speed of the engine 17 to an arbitrary rotation speed from the driver.
회전수가속 입력부는, 운전자로부터 엔진의 회전수를 증가시키는 회전수가속 입력을 받는다. 도 1의 회전수가속 입력부는 페달(15)과 검출 수단(16)을 포함한다. 운전자는 엔진 회전수를 증가시키기 위하여 페달(15)을 밟는다. 검출 수단(16)은 페달(15)의 작동을 검출한다. 검출 수단(16)은 페달(15)이 밟혀진 변위를 감지하기 위한 위치 센서일 수도 있다. 이 경우, 회전수가속 입력은 페달의 변위가 된다. 또한, 검출 수단(16)은 페달(15)이 주행과 연동한 유압식 감압밸브일 경우, 밟혔을 때의 신호 압력을 감지하기 위한 압력 센서일 수 있다. 이 경우, 회전수가속 입력은 페달이 밟혀지는 신호 압력이 된다. 회전수가속 입력에 의해 정해지는 엔진의 회전수는 페달(15)의 눌려진 변위 또는 압력의 크기에 비례한다. The rotation speed acceleration input unit receives a rotation speed acceleration input for increasing the rotation speed of the engine from the driver. The rotation speed acceleration input part of FIG. 1 includes a pedal 15 and a detection means 16. The driver steps on the pedal 15 to increase the engine speed. The detection means 16 detects the operation of the pedal 15. The detection means 16 may be a position sensor for detecting the displacement on which the pedal 15 is stepped. In this case, the rotation speed acceleration input becomes the displacement of the pedal. In addition, the detecting means 16 may be a pressure sensor for detecting a signal pressure when the pedal 15 is stepped when the pedal 15 is a hydraulic pressure reducing valve in conjunction with driving. In this case, the rotation speed acceleration input becomes the signal pressure at which the pedal is pressed. The speed of the engine, determined by the speed input, is proportional to the magnitude of the pressure or the displacement of the pedal 15.
제어부(11)는 엔진의 회전수를 제어한다. 엔진(17)에는 엔진(17)의 회전수를 조절하기 위한 전자식 거버너(30)가 구비되어 있다. 제어부(11)와 전자식 거버너(30) 사이에는 통신 수단(32)이 연결되어 있다. 제어부는 회전수설정 입력에 의하여 설정된 회전수 및/또는 회전수가속 입력에 따라 정해지는 회전수로 엔진(17)의 회전수를 제어하도록 하는 제어 신호를 전자식 거버너(30)로 전송한다. 전자식 거버너(30)는 제어부로부터 전송되는 제어 신호에 따라 엔진 회전수가 출력되도록 연료 분사량을 조절하는 장치(도시되지 않음)의 개구 면적을 조절하게 된다.The control unit 11 controls the rotation speed of the engine. The engine 17 is equipped with an electronic governor 30 for adjusting the rotation speed of the engine 17. The communication means 32 is connected between the control part 11 and the electronic governor 30. The controller transmits a control signal to the electronic governor 30 to control the rotation speed of the engine 17 at a rotation speed determined by the rotation speed setting input and / or the rotation speed determined according to the rotation speed acceleration input. The electronic governor 30 adjusts the opening area of an apparatus (not shown) for adjusting the fuel injection amount so that the engine speed is output according to a control signal transmitted from the controller.
도 2는 도 1의 종래 엔진 회전수 오버라이드 제어장치에 있어서, i) 회전수설정 입력에 의하여 설정된 회전수, ii) 회전수가속 입력에 의해 정해지는 회전수 및 iii) 엔진 회전수 오버라이드 제어장치에 의하여 제어되는 엔진의 최종 출력 회전수의 관계를 보여주는 그래프이다. Figure 2 is a conventional engine speed override control apparatus of Figure 1, i) the speed set by the rotation speed setting input, ii) the speed determined by the speed input and iii) the engine speed override control device This graph shows the relationship between the final output speed of the engine controlled by the engine.
휠타입 건설기계의 경우, 특정 엔진 회전수로 설정하여 작업 중, 짧은 시간 동안 마력의 증대 혹은 엔진 회전수의 증대가 필요한 경우, 가속페달을 밟으면 엔진 회전수 등이 증가하게 되는 엔진 스피드 오버라이드 기능이 채택되어 있다. In the case of wheel type construction machines, if the engine speed or the engine speed is increased for a short time during the operation by setting the specific engine speed, the engine speed override function increases the engine speed when the accelerator pedal is pressed. Adopted.
이러한 건설기계에서, 제어부(11)는 회전수설정 입력에 의해 설정된 회전수와 회전수가속 입력에 의해 정해지는 엔진의 회전수를 비교한다. 이 때, 회전수가속 입력에 의해 정해지는 회전수가 회전수설정 입력에 의하여 설정된 회전수보다 낮으면 제어부(11)는 회전수설정 입력에 의해 설정된 회전수로 엔진의 회전수를 제어한다. 그러나, 회전수가속 입력에 의해 정해지는 회전수가 회전수설정 입력에 의하여 설정된 회전수보다 커지면, 제어부(11)는 회전수가속 입력에 의해 정해지는 회전수로 엔진의 회전수를 제어하게 된다. 따라서, 엔진은 페달이 밟혀지는 초기에는 회전수설정 입력에 따른 회전수로 구동되고, 후기에는 회전수가속 입력에 따른 회전수로 구동된다. In this construction machine, the control unit 11 compares the rotational speed set by the rotational speed setting input with the rotational speed of the engine determined by the rotational speed acceleration input. At this time, if the rotation speed determined by the rotation speed acceleration input is lower than the rotation speed set by the rotation speed setting input, the control unit 11 controls the rotation speed of the engine by the rotation speed set by the rotation speed setting input. However, when the rotation speed determined by the rotation speed acceleration input becomes larger than the rotation speed set by the rotation speed setting input, the control unit 11 controls the rotation speed of the engine by the rotation speed determined by the rotation speed acceleration input. Therefore, the engine is driven at the rotational speed according to the rotational speed setting input at the initial stage when the pedal is pressed, and is driven at the rotational speed according to the rotational speed acceleration input later.
그러나, 도 1 및 도 2의 엔진 회전수 오버라이드 제어장치는 도 3에 도시한 바와 같은 문제점을 노출한다. 도 3은 도 2 에 있어서, 회전수설정 입력에 의하여 설정된 회전수 별, 최종 출력 회전수를 보여주는 그래프이다.However, the engine speed override control device of Figs. 1 and 2 exposes the problem as shown in Fig. 3. 3 is a graph showing the final output rotation speed for each rotation speed set by the rotation speed setting input in FIG. 2.
전술한 바와 같이, 종래의 오버라이드 기능은, 페달을 밟아 요구된 엔진 회전수와 현재 설정된 엔진 회전수의 크기를 비교하여, 둘 중 큰 엔진 회전수를 따라가는 식으로 구현이 되어 있다. 따라서, 운전자가 얼마간의 페달을 밟더라도 바로 엔진 회전수의 증가로 이어지지 않고 아무런 반응이 없다가, 일정 이상 밟아 회전수가속 입력에 의해 정해지는 회전수가 현재 설정된 엔진 회전수 이상이 되었을 때 부터 엔진 회전수가 오버라이드 되게 되는 데드존 구간이 발생하게 된다. 이 때문에 운전자에게 페달 조작에 아무런 응답을 주지 않다가, 운전자가 예기치 못한 시점에 갑작스럽게 회전수가 증가되어 운전자에게 조작 충격을 주게 되는 문제점이 있었다.As described above, the conventional override function is implemented by following a larger engine speed by comparing the required engine speed with a currently set engine speed by pressing a pedal. Therefore, even if the driver presses some pedal, the engine speed does not immediately increase and there is no reaction, and when the driver presses the engine for a certain time, the engine speed starts from when the speed determined by the speed input becomes higher than the currently set engine speed. A dead zone occurs where the number is overridden. For this reason, there is a problem in that the driver is not responded to the pedal operation at all, and the driver suddenly increases the rotation speed at an unexpected time to give the driver an operation shock.
도 3의 예를 들어보면, 회전수설정 입력에 의하여 R2의 회전수로 설정하여 작업을 하다가 가속페달을 밟을 때와, 회전수설정 입력에 의하여 R1의 회전수로 설정하여 작업을 하다가 가속페달을 밟을 때를 비교하면, 후자의 경우에 페달을 좀 더 밟아야 엔진 회전수가 증가하게 되는데, 운전자는 이 감의 차이를 설정 회전수 단계 별로 모두 익혀야 되는 문제점이 있는 것이다.In the example of FIG. 3, when the accelerator pedal is pressed while the work is set to the rotation speed of R2 by the rotation speed setting input, the accelerator pedal is set while the work is set to the rotation speed of R1 by the rotation speed setting input. In comparison with the stepping step, in the latter case, the engine speed should be increased by stepping on the pedal a little more, and the driver has to learn all the differences in the set speed step by step.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 가속페달을 밟는 순간부터 지연 없이 엔진 회전수가 오버라이드 될 수 있도록 하여, 운전자의 의도대로 장비 엔진 회전수 혹은 마력이 조작될 수 있도록 하는 것이다.The present invention has been made to solve the above problems, an object of the present invention is to allow the engine speed can be overridden without a delay from the moment of stepping on the accelerator pedal, the machine engine speed or horsepower can be manipulated as the driver intended To ensure that

이하, 첨부도면을 참조하여 본 발명의 실시예를 상세히 설명한다. Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
도 4는 엔진 회전수 오버라이드 제어장치의 구성을 개략적으로 보여주는 도면이다. 4 is a view schematically showing the configuration of the engine speed override control device.
도시한 바와 같이, 엔진 회전수 오버라이드 제어장치는, 회전수설정 입력부(34), 회전수가속 입력부(14) 및 제어부(11)를 포함한다. As shown in the figure, the engine speed override control apparatus includes a rotation speed setting input section 34, a rotation speed acceleration input section 14, and a control unit 11.
본 발명의 엔진 회전수 오버라이드 제어장치는 전형적으로는, 휠 타입 굴삭기에 적용되지만, 반드시 이에 한정되지 않고, 기타 적용 가능한 기계, 특허 건설기계에 적용될 수 있다. 또한, 도 4의 장치는 타 구성부와의 관계에서, 도 1의 장치와 같이 유사하게 구체화될 수 있으나, 반드시 이에 한정되는 것은 아니다. The engine speed override control apparatus of the present invention is typically applied to a wheel type excavator, but is not necessarily limited thereto, and may be applied to other applicable machines and patent construction machines. In addition, the apparatus of FIG. 4 may be embodied similarly to the apparatus of FIG. 1 in relation to other components, but is not necessarily limited thereto.
회전수설정 입력부(34)는 엔진(17)의 회전수를 임의의 회전수(Ra)로 설정하는 회전수설정을 입력 받는다. 회전수설정 입력부(34)는 전형적으로 회전수를 불연속적, 단계별로 설정하기 위한 다이얼, 레버, 버튼, 등 다양한 형태의 입력 장치이다. The rotation speed setting input unit 34 receives a rotation speed setting for setting the rotation speed of the engine 17 to an arbitrary rotation speed Ra. The rotational speed setting input unit 34 is typically various types of input devices such as dials, levers, buttons, etc. for setting the rotational speed discontinuously and stepwise.
회전수가속 입력부(14)는 엔진(17)의 회전수를 증가시키는 회전수가속 입력(X)을 받는다. 회전수가속 입력부(14)는, 전형적으로는 가속페달이 이에 해당된다. 이 경우, 회전수가속 입력(X)은 가속페달의 변위 또는 가속페달이 밟혀지는 압력이 된다. 그러나, 본 발명의 회전수가속 입력부(14)는 가속페달에 한정되지 않고, 다이얼, 레버, 등 기타 다양한 형태의 입력 장치가 될 수 있다. 페달은, 페달이 밟혀지는 초기에 자유 유격을 가질 수 있다. (도 5 참조) 자유 유격 구간에서는 페달이 밟혀지더라도 회전수가속 입력으로서 처리되지 않는다. 따라서, 자유 유격 구간에서는 페달이 밟혀지더라도 엔진 회전수가 가속되지 않는다. The rotation speed acceleration input unit 14 receives a rotation speed acceleration input X for increasing the rotation speed of the engine 17. The rotation speed acceleration input unit 14 typically corresponds to an accelerator pedal. In this case, the rotation speed acceleration input X becomes the displacement of the accelerator pedal or the pressure at which the accelerator pedal is pressed. However, the rotation speed acceleration input unit 14 of the present invention is not limited to an accelerator pedal, and may be a dial, a lever, or other various types of input devices. The pedal may have a free play at the initial step of pedaling. (See FIG. 5) In the free play section, even if the pedal is stepped, the rotation speed is not treated as an acceleration input. Therefore, the engine speed is not accelerated even when the pedal is stepped in the free play section.
제어부(11)는 회전수설정 입력부(34)로부터 회전수설정 입력을 전송 받고, 회전수가속 입력부(14)로부터 회전수가속 입력을 전송 받아, 이를 바탕으로 산출된 회전수 제어 신호를 엔진(17)에 전송한다. The control unit 11 receives the rotation speed setting input from the rotation speed setting input unit 34, receives the rotation speed acceleration input from the rotation speed acceleration input unit 14, and outputs a rotation speed control signal calculated based on the engine 17. To be sent).
도 5는 본 발명의 일 실시예에 따른 엔진 회전수 오버라이드 제어장치에 있어서, i) 회전수설정 입력에 의하여 설정된 회전수, ii) 회전수가속 입력에 의해 정해지는 회전수 및 iii) 엔진 회전수 오버라이드 제어장치에 의하여 제어되는 엔진(17)의 최종 출력 회전수의 관계를 보여주는 그래프이다. 5 is an engine speed override control apparatus according to an embodiment of the present invention, i) the speed set by the rotation speed setting input, ii) the speed determined by the rotation speed input and iii) the engine speed It is a graph showing the relationship between the final output rotational speed of the engine 17 controlled by the override controller.
회전수가속 입력부(14)를 통한 회전수설정 입력이 없는 상태에서, 회전수가속 입력부(14)를 통하여 회전수가속 입력(X)이 입력되면, 제어부(11)는 회전수가속 입력(X)의 크기에 비례하는 회전수(Rb)가 엔진(17)의 회전수가 되도록 제어한다. When there is no rotation speed setting input through the rotation speed input unit 14 and the rotation speed input X is input through the rotation speed input unit 14, the controller 11 receives the rotation speed input X. The speed Rb proportional to the size of the control is controlled to be the speed of the engine 17.
회전수설정 입력에 의하여 설정된 임의의 회전수(Ra)로 엔진(17)이 구동되는 상태에서, 회전수가속 입력부(14)를 통하여 회전수가속 입력(X)이 입력되면, 제어부(11)는 (임의의 회전수(Ra)+ 회전수가속 입력(X)의 크기에 비례하는 회전수 증가분(ΔR))이 엔진(17)의 회전수가 되도록 제어한다. 여기서, 비례는 선형 비례 관계에 한정되지 않고, 회전수가속 입력의 크기가 증가함에 따라 회전수 증가분(ΔR)의 크기가 커지는 다양한 관계를 모두 포함한다.In the state where the engine 17 is driven at an arbitrary speed Ra set by the rotation speed setting input, when the rotation speed acceleration input X is input through the rotation speed acceleration input unit 14, the control unit 11 (The arbitrary rotation speed Ra + the rotation speed increment ΔR proportional to the magnitude of the acceleration input X) is controlled to be the rotation speed of the engine 17. Here, the proportion is not limited to the linear proportional relationship, and includes all the various relationships in which the magnitude of the rotation increase ΔR increases as the magnitude of the rotation speed acceleration input increases.
제어부(11)는, (임의의 회전수(Ra)+ 회전수가속 입력(X)의 크기에 비례하는 회전수 증가분(ΔR))이 최대값에 도달하게 하는 회전수가속 입력(X2) 값과 회전수가속 입력(X)의 크기에 비례하는 회전수(Rb)가 최대값에 도달하게 하는 회전수가속 입력(X2) 값이 일치되도록 제어할 수 있다. The control unit 11 includes a rotation speed acceleration input (X2) value that allows (any rotation speed Ra + rotation speed increment ΔR proportional to the magnitude of the rotation speed input X) to reach a maximum value. The rotation speed Rb, which is proportional to the magnitude of the rotation speed acceleration input X, may be controlled to coincide with the rotation speed acceleration input X2.
이를 통하여, 운전자에게 예측 가능한 최대 회전수와 그에 대응되는 페달 조작감을 일관되게 제공할 수 있게 된다. Through this, it is possible to consistently provide the driver with a predictable maximum rotation speed and a corresponding pedal operation feeling.
또한, 응답 특성의 측면에서도, 본 발명은 운전자의 조작에 대한 우수한 응답 특성을 제공할 수 있다. 운전자가 가속페달을 밟는다는 것은, 현재 설정된 회전수보다 회전수를 높이고자 하는 의도에서 비롯된 것이다. 그러나, 종래의 장치에서는 데드존 구간 동안 아무런 응답을 보이지 않다가, 갑자기 급격한 기울기로 회전수를 증가시켜 운전자에게 조작 충격을 준다. 이에 반하여, 본 발명은 운전자의 조작 의도에 곧바로 응답하여 회전수를 증가시키고, 또한 완만한 기울기로 회전수를 증가시켜 운전자에게 조작 충격을 주지 않는다. 회전수가 완만한 기울기로 증가된다고는 하지만, 그 회전수(예컨대, 도 5의 R3)는 종래의 급격한 기울기로 증가되는 회전수(예컨대, 도 5의 R4)보다 커, 순간적으로 큰 회전수를 얻고자 하는 운전자의 의도에 부합되는 것이다. Also in terms of response characteristics, the present invention can provide excellent response characteristics to the driver's operation. The driver's stepping on the accelerator pedal comes from the intention to increase the number of revolutions above the currently set number of revolutions. However, in the conventional apparatus, no response is shown during the dead zone section, and suddenly the rotation speed is increased with a sharp inclination to give the driver an operation shock. On the contrary, the present invention increases the rotational speed in response to the driver's operation intention, and also increases the rotational speed with a gentle inclination so as not to give the driver an operation shock. Although the rotational speed is increased with a gentle slope, the rotational speed (e.g., R3 in FIG. 5) is greater than the conventional rotational speed (e.g., R4 in FIG. 5), resulting in an instantaneous larger rotational speed. It is in line with the intention of the driver.
본 발명은 다음과 같은 단계로 구성될 수 있다. The present invention can be composed of the following steps.
마력설정 혹은 회전수설정 입력부(34)를 통하여 입력되어 설정된 엔진(17)의 회전수(Ra)를 산출하는 제1단계, 가속페달 조작량을 검출하는 제2단계, i) 증가될 수 있는 회전수의 최대값과 ii) 제1단계에서 설정된 회전수, 그리고 iii) 제2단계에서 검출된 가속페달 조작량를 바탕으로 도 5의 그래프와 같은 형태의 최종 출력 엔진 회전수를 계산하는 제3단계, 계산된 최종 출력 엔진 회전수로 엔진(17)의 회전수를 제어하는 제4단계.A first step of calculating the rotation speed Ra of the engine 17 inputted through the horsepower setting or the speed setting input unit 34, a second step of detecting the accelerator pedal manipulation amount, i) the number of rotations that may be increased A third step of calculating the final output engine speed in the form of the graph of FIG. 5 based on the maximum value of and ii) the rotation speed set in the first step, and iii) the accelerator pedal operation amount detected in the second step, the calculated A fourth step of controlling the rotation speed of the engine 17 at the final output engine speed.
본 발명에서는, 설정되어 있는 엔진 회전수를 시작점으로 하여 엔진 회전수가 데드존 없이 즉시 증가된다. In the present invention, the engine speed is immediately increased without a dead zone by using the set engine speed as a starting point.
도 6은 도 5에 있어서, 회전수설정 입력에 의하여 설정된 회전수 별, 최종 출력 회전수를 보여주는 그래프이다.FIG. 6 is a graph showing the final output rotation speed for each rotation speed set by the rotation speed setting input in FIG. 5.
도시한 바와 같이, 회전수설정 입력에 의하여 R2의 회전수로 설정하여 작업을 하다가 가속페달을 밟을 때와, 회전수설정 입력에 의하여 R1의 회전수로 설정하여 작업을 하다가 가속페달을 밟을 때를 비교하면, 양자 모두 동일한 페달 조작에 의하여 회전수 가속 응답이 이루진다. 따라서, 현재 설정된 엔진 회전수 단계에 관계없이 항상 같은 조작감으로 가속페달을 밟을 수 있게 되어, 운전자가 가속페달을 밟을 때의 불확실성과 조작 충격이 없게 된다.As shown in the figure, when the accelerator pedal is pressed while the work is set to the rotation speed of R2 by the rotation speed setting input and when the accelerator pedal is pressed while the work is set to the rotation speed of R1 by the rotation speed setting input, In comparison, the rotation speed acceleration response is achieved by the same pedal operation for both. Therefore, the accelerator pedal can always be stepped with the same feeling of operation irrespective of the currently set engine speed step, so that there is no uncertainty and no operating shock when the driver presses the accelerator pedal.
도시한 바와 같이 회전수 가속이 시작되는 회전수가속 입력은 설정된 엔진 회전수 단계에 관계 없이 X1으로 동일하다. 또한, 회전수 가속이 완성되어 최대 회전수에 도달하게 하는 회전수 가속 입력도 설정된 엔진 회전수 단계에 관계 없이 X2로 동일하다. As shown, the speed acceleration input at which the speed acceleration starts is equal to X1 regardless of the set engine speed step. In addition, the rotational acceleration input which completes the rotational acceleration to reach the maximum rotational speed is also the same as X2 regardless of the set engine rotational stage.
다만, 최대 회전수가 일정하게 제한됨에 따라, 설정된 임의의 회전수(Ra)의 크기에 따라, 회전수가속 입력(X)의 크기에 비례하는 회전수 증가분(ΔR)의 크기는 다르다. 예컨대, 설정된 임의의 회전수(Ra)의 크기가 클수록, 회전수가속 입력(X)의 크기에 비례하는 회전수 증가분(ΔR)의 크기는 작도록 제어될 수 있다.However, since the maximum rotational speed is constantly limited, the magnitude of the rotational increment ΔR proportional to the magnitude of the rotational speed acceleration X is different depending on the magnitude of the predetermined rotational speed Ra. For example, the larger the magnitude of the predetermined rotational speed Ra, the smaller the magnitude of the rotation increase ΔR proportional to the magnitude of the rotational speed input X may be controlled.
