Description
본 고안은 자동변속차량에 관한 것으로서, 특히 자동변속차량이 일정각도를 가진 등판길에서 정차후 주행을 하게 될 때 차량의 밀림을 방지할 수 있도록 한 자동변속차량의 밀림 방지장치에 관한 것이다.The present invention relates to an automatic transmission vehicle, and more particularly, to an automatic transmission vehicle's rolling prevention device to prevent the vehicle's rolling when the vehicle is traveling after stopping at a climbing road having a certain angle.
일반적으로 차량에는 잘 알려진 바와 같이 엔진에서 연료를 연소시켜 여기에서 발생되는 열에너지를 운동에너지로 전환하는 내연기관을 이용하는 것으로서, 화물의 운송 및 이동수단으로 이용되고 있는 것이다.In general, a vehicle uses an internal combustion engine that burns fuel in an engine and converts thermal energy generated therein into kinetic energy, and is used as a means of transporting and transporting cargo.
이러한, 자동차는 엔지의 구동력을 절절히 제어하여 차축(구동륜)으로 전달하는 변속장치를 포함하고 있다.Such an automobile includes a transmission for precisely controlling the driving force of the engine and transmitting it to the axle (drive wheel).
이러한, 변속장치는 엔진의 초기구동시에는 충분한 구동력을 갖지 못하므로 초기구동시에 엔진의 회전력을 감속시켜 구동토오크를 크게하거나, 속도증가시에 감속비를 변환하게 된다. 또는 감속비를 증속시켜 차량의 주행상태에 따라 적절하게 조작 또는 자동으로 작동하게 된다.Since the transmission does not have sufficient driving force at the time of initial driving of the engine, it reduces the rotational force of the engine at the time of initial driving to increase the driving torque, or convert the reduction ratio when the speed increases. Alternatively, the gear ratio may be increased to operate properly or automatically according to the driving state of the vehicle.
이러한, 변속장치는 여러종류가 개발되어있는바 그 예를 들면, 수동변속장치(Manual Transmission) 및 자동변속장치(Auto Transmission)으로 구분된다.Such a transmission device has been developed in several types, for example, it is divided into a manual transmission (Manual Transmission) and an automatic transmission (Auto Transmission).
상기 전자의 수동변속장치는 각각의 주행조건에 따라 운전자가 기어비를 선택하게 되는 것으로 조작이 어려워 숙련된 운전기술을 요하게 된다.The electronic manual transmission is difficult for the driver to select a gear ratio according to each driving condition, requiring skilled driving skills.
한편, 후자의 자동변속장치는 차량의 주행속도 및 부하상태 등을 감지하는 각종 센서로부터 입력되는 컴퓨터의 전자제어신호 및 이 신호에 따라 개폐되는 각종 밸브 등에 의해 유성기어 조립체가 작절하게 제어되는 것이 의해 자동적으로 변속을 실시토록 하는 것이다.On the other hand, in the latter automatic transmission, the planetary gear assembly is controlled by an electronic control signal of a computer input from various sensors for detecting the vehicle's traveling speed and load state, and various valves that open and close according to the signal. It is to shift automatically.
이러한, 자동변속장치는 수동변속장치에 비해 구조가 복잡하고, 출력효율이 떨어지며, 고가라는 단점이 있으나, 주행중 변속을 위한 별도의 조작을 수행하지 않아도 되기 때문에 조작이 간편하다는 큰 장점을 가지고 있어 최근에 그 이용범위가 급속히 확대되고 있는 실정이다.This automatic transmission has a disadvantage in that the structure is complicated, the output efficiency is low, and expensive compared to the manual transmission, but the operation is easy because it does not need to perform a separate operation for shifting while driving. Therefore, the scope of use is rapidly expanding.
또한, 이와 같은 자동변속장치를 장착한 차량은 토오크 컨버터에서 유체에 의하여 동력의 전달이 이루어짐으로써, 초기구동력이 높으며 수동변속차량과는 달이 클러치없이 셀렉터레버(Selector Lever)조작으로만 동력이 전달이 이루어지게 된다. 따라서, 등판로 출발시 경사가 아주 심하지 않은 경우에 초보자의 경우에도 뒤로 밀림없이 출발이 가능한 것이다.In addition, a vehicle equipped with such an automatic transmission has a high initial driving force by transmitting fluid by a fluid in a torque converter, and power is transmitted only by a selector lever operation without a clutch, unlike a manual transmission vehicle. This is done. Therefore, when the slope is not very severe at the start of the climb, even a beginner can start without being pushed back.
그리고, 셀렉터레버를 "N"에서 "D"로 변경하게 되는 경우에도 차량의 아이들 퀄리티(Idle Quality)와 안정도(Stability)를 위해 엔진 RPM은 크게 변동없이 동일하게 되는 것이다.In addition, even when the selector lever is changed from "N" to "D", the engine RPM is the same without any change for the idle quality and stability of the vehicle.
이 외에도 최근에는 변속시 변속단을 제거하여 변속충격이 전혀 발생하지 않도록 하는 이른바 무단변속기(Stepless Transmission)가 개발되고 있다.In addition, recently, a so-called stepless transmission has been developed to remove a shift stage so that a shift shock does not occur at all.
이상에서 살펴본 바와 같은 종래의 자동변속차량은 경사각이 심한 등판길에서 일시 정차후 출발을 하게되는 경우 차량이 뒤로 밀리게 되어 이로인한 사고시 물적/인적피해가 발생가능한 문제점이 있다.As described above, the conventional automatic transmission vehicle has a problem that physical / personal damage may occur in case of an accident caused by the vehicle being pushed backward when starting after a temporary stop on a steep incline.
그리고, 보통 자동변속차량의 운전자는 등판길 밀림현상을 대처하는 능력이 대체적으로 수동변속차량의 운전자에 비해 미숙한 경향이 있다.In general, the driver of the automatic transmission vehicle tends to be immature compared to the driver of the manual transmission vehicle.
따라서, 본 고안은 상기한 종래 기술에 따른 제반 문제점을 해결하기 위하여 안출한 것으로, 본 고안의 목적은 자동변속차량이 일정각도를 가진 등판길에서 정차후 출발을 하게 될 때 차량의 밀림을 방지할 수 있도록 한 자동변속차량의 밀림 방지장치를 제공함에 있다.Therefore, the present invention is devised to solve the above problems according to the prior art, the object of the present invention is to prevent the rolling of the vehicle when the automatic transmission vehicle starts after the stop on the slope with a certain angle An anti-rolling device for an automatic transmission vehicle is provided.

이상에서와 같은 구성을 갖는 본 고안에 따른 자동변속차량의 밀림 방지장치의 동작을 살펴보기로 하자.Let's look at the operation of the apparatus for preventing an automatic transmission vehicle according to the present invention having the configuration as described above.
먼저, 자동변속차량이 주행을 하다가 일정각도를 가지는 등판길에서 정차를 하게 되면 액셀페달신호검출부(12)와, 셀렉터레버위치검출부(13) 및 브레이크신호검출부(14)에서 각각 액셀신호 온/오프상태와 셀렉터레버위치 및 브레이크신호 온/오프상태를 각각 검출하여 제어부(15)로 인가하게 된다.First, when the automatic transmission vehicle stops on a climbing road having a certain angle, the accelerator pedal signal detection unit 12, the selector lever position detection unit 13, and the brake signal detection unit 14 respectively turn on / off the accelerator signal. The state, the selector lever position, and the brake signal on / off state are respectively detected and applied to the controller 15.
만약, 상기 각각의 검출부(12, 13, 14)에서 검출된 신호가 인가되면 즉, 액셀신호가 오프이고, 셀렉터레버위치가 "D"이며, 브레이크신호가 온상태인 경우 제어부(15)는 차량이 일정각도의 등판길에서 정차하고 있는 상태로 판단하여 경사각검출부(10)에 구동 제어신호를 제공하여 현재 차량의 위치의 등판길의 경사각을 검출하도록하여 제어부(15)로 인가한다.If a signal detected by each of the detection units 12, 13, and 14 is applied, that is, the accelerator signal is off, the selector lever position is "D", and the brake signal is on, the controller 15 controls the vehicle. It is determined that the vehicle is stopped at the climbing road at a predetermined angle, and the driving control signal is provided to the inclination angle detection unit 10 so as to detect the inclination angle of the climbing road at the current position of the vehicle and applied to the controller 15.
이상태에서 운전자가 출발을 위해 브레이크신호를 오프시키면 즉, 브레이크페달로부터 발을 떼게 되면 초기구동력검출부(11)에서는 그 순간의 초기구동력(Ff)즉, 그 순간의 엔진 RPM을 검출하여 제어부(15)로 인가한다.In this state, when the driver turns off the brake signal for starting, that is, when the driver releases the brake pedal, the initial driving force detection unit 11 detects the initial driving force F f at that moment, that is, the engine RPM at that moment, and controls the controller 15. Is applied.
제어부(15)는 인가되는 경사각도를 이용하여 차량이 현재 뒤로 밀리는 힘(F1)을 계산하여 상기 초기구동력검출부(11)에서 검출된 차량의 초기구동력(Ff)와 그 브기를 비교하게 된다.The controller 15 calculates a force F 1 currently being pushed backward by the vehicle using the inclination angle applied, and compares the initial driving force F f of the vehicle detected by the initial driving force detection unit 11 with its size. .
비교결과, 뒤로 밀리게 되는 힘(F1)이 차량의 초기구동력(Ff)보다 클 경우에는 차량이 뒤로 밀리게 되기 때문에 이에 대한 보상값 즉, F1- Ff값을 계산하여 그 만큼의 구동력을 증가시키기 위한 제어신호를 IACV(16)으로 제공하여 상기 그 만큼의 구동력을 증대시키도록 하는 것이다. 따라서, 차량이 뒤로 밀리게 되는 힘(F1)과 차량의 초기구동력(Ff)값이 서로 동일하거나 크기 때문에 차량은 뒤로 밀리지 않게 되는 것이다.The result of comparison, if milli force (F 1) that is to the back is greater than the initial force (F f) of the vehicle, i.e., the compensation value for it, because the vehicle is being pushed back, F 1 - to calculate the F f value of that by The control signal for increasing the driving force is provided to the IACV 16 so as to increase the driving force. Therefore, the vehicle is not pushed back because the force F 1 that the vehicle pushes backward and the initial driving force F f of the vehicle are equal to or greater than each other.
이상에서와 같은 본 고안에 따른 자동변속차량의 밀림 방지장치의 동작을 도 2를 참조하여 단계적으로 살펴보기로 하자.With reference to Figure 2 will be described step by step operation of the automatic transmission vehicle rolling prevention device according to the present invention as described above.
도 2는 본 고안에 따른 자동변속차량의 밀림 방지장치의 동작을 나타낸 동작 플로우챠트를 나타낸 도면이다.2 is a view showing an operation flowchart showing the operation of the rolling prevention device of the automatic transmission vehicle according to the present invention.
차량이 주행하다가 일정각도를 가진 등판길에 정차를 하게 되는 경우 액셀온/오프상태와, 브레이크 온/오프상태 및 셀렉터레버의 현재위치를 각각 검출하게 된다(S101).When the vehicle stops on the climbing road having a predetermined angle while driving, the accelerator on / off state, the brake on / off state, and the current position of the selector lever are respectively detected (S101).
검출결과, 액셀상태가 오프이고, 브레이크상태가 온이며, 셀렉터레버의 위치가 "D"인가를 판단하여(S102) 액셀상태가 오프이고, 브레이크상태가 온이며, 셀렉터레버의 위치가 "D"이면, 정지상태인 차량의 각도 즉, 도로의 경사각을 검출하게 된다(S103).As a result of the detection, it is determined whether the accelerator state is off, the brake state is on, and the position of the selector lever is "D" (S102). The accelerator state is off, the brake state is on, and the position of the selector lever is "D". In this case, the angle of the vehicle in the stopped state, that is, the inclination angle of the road is detected (S103).
이때, 차량의 브레이크가 오프되는 순각 즉, 운전자가 출발을 위해 브레이크 페달에서 발을 떼는 순간 차량의 초기구동력(Ff)을 검출하고, 상기 검출된 경사각을 이용하여 차량이 뒤로 밀리려는 힘(F1)을 계산하게 된다(S104).At this time, the moment that the brake of the vehicle is turned off, that is, the initial driving force F f of the vehicle is detected at the moment when the driver releases the brake pedal for starting, and the force F that the vehicle pushes back by using the detected inclination angle 1 ) is calculated (S104).
이렇게 계산된 초기구동력(Ff)이 차량이 뒤로 밀리려는 힘(F1)보다 작은가를 판단하여(S105) 초기구동력(Ff)이 차량이 뒤로 밀리려는 힘(F1)보다 큰 경우에는 현재의 초기구동력을 이용하여 주행을 하게 되고(S107), 반대로 초기구동력(Ff)이 차량이 뒤로 밀리려는 힘(F1)보다 작을 경우에는 차량이 뒤로 밀리게 되는 상황이 발생할 수 있는 것으로 판단하여 보상값 즉, Ff- F1을 계산하여 계산된 보상값만큼의 구동력을 증대시켜(S106) 차량이 뒤로 밀리게 되는 것을 방지하도록 한 것이다.본 고안을 요약하면, 차량이 경사로에서 뒤로 미끄러지려는 힘은 경사각도가 클수록 커지게 된다. 이에 대해 차량의 초기구동력이 상기 차량이 미끄러지려는 힘보다 작을 경우 차량의 미끄짐이 발생하게 된다. 따라서, 경사로의 경사각을 검출하여 차량이 밀리게 되는 힘과 차량의 초기구동력을 각각 검출하고, 검출된 차량이 밀리게 되는 힘이 차량의 초기구동력보다 클 경우 이에 대응되는 구동력의 증가량을 IACV(16)을 통하여 컨트롤하여 차량이 뒤로 밀리지 않도록 한 것이다.It is determined whether the initial driving force (F f ) calculated in this way is smaller than the force (F 1 ) that the vehicle pushes backward (S105). When the initial driving force (F f ) is larger than the force (F 1 ) that the vehicle pushes backward, the current The driving is performed using the initial driving force of (S107), on the contrary, if the initial driving force (F f ) is smaller than the force (F 1 ) that the vehicle is pushing backward, it is determined that the situation that the vehicle is pushed backward may occur. Compensation value, that is, F f -F 1 is calculated to increase the driving force by the calculated compensation value (S106) to prevent the vehicle from being pushed back. The force increases as the inclination angle increases. On the other hand, when the initial driving force of the vehicle is smaller than the force that the vehicle is to slip, the vehicle is slipped. Therefore, the inclination angle of the ramp is detected to detect the force pushed by the vehicle and the initial driving force of the vehicle, respectively. When the detected force pushed by the vehicle is greater than the initial driving force of the vehicle, the corresponding increase in driving force is calculated by the IACV (16). ) To prevent the vehicle from being pushed back.
상술한 바와 같이, 본 고안에 따른 자동변속차량의 밀림 방지장치는 차량이 정차하고 있는 경사로의 경사각을 검출하여 차량이 밀리게 되는 힘과 차량의 초기구동력을 각각 검출하고, 검출된 차량이 밀리게 되는 힘이 차량의 초기구동력보다 클 경우 이에 대응되는 구동력의 증가량을 IACV(16)을 통하여 컨트롤하여 줌으로써, 심한 경사로에서 출발을 할 경우 차량이 뒤로 밀리는 현상을 방지할 수 있는 이점이 있다. 따라서, 차량의 밀림으로 인해 뒤차량과의 충돌사고를 미연에 방지할 수 있는 효과가 있다.As described above, the rolling prevention device of the automatic transmission vehicle according to the present invention detects the inclination angle of the inclination of the vehicle is stopped, the force to push the vehicle and the initial driving force of the vehicle, respectively, and the detected vehicle to push If the force is greater than the initial driving force of the vehicle by controlling the increase in the corresponding driving force through the IACV (16), there is an advantage that can prevent the phenomenon that the vehicle is pushed back when starting from a severe slope. Therefore, there is an effect that can prevent the collision accident with the rear vehicle due to the rolling of the vehicle in advance.
