자동변속기의 슬립 락업 제어장치 및 방법{SYSTEM FOR CONTROL SLIP LOCK UP OF AUTOMATIC TRANSMISSION ON VEHICLE AND METHOD THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic transmission control system,

본 발명은 자동변속기에 관한 것으로, 보다 상세하게는 엔진 회전수의 변동량을 고려한 슬립 락업 제어(Slip Lock up)로 구동계의 NVH(Noise, Vibration and Harshness)성능 향상을 제공하는 자동변속기의 슬립 락업 제어장치 및 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic transmission, and more particularly, to a slip lock-up control of an automatic transmission that provides improved NVH (Noise, Vibration and Harshness) performance of a driveline by slip lock- Apparatus and method.

일반적으로, 자동차에 대한 소비자의 편의 욕구에 따라 자동변속기가 보편적으로 사용되고 있으나, 연비에서 수동변속기에 비해 매우 불리하다.Generally, an automatic transmission is commonly used in accordance with the consumer's convenience to the automobile, but it is very disadvantageous in the fuel economy as compared with the manual transmission.

따라서, 자동변속기의 편의성과 수동변속기의 효율을 제공하기 위하여 특정 영역에서 토크 컨버터의 펌프 축과 터빈 축을 함께 직결시켜 동력 손실을 최소화하고, 이를 통해 연비 향상을 제공하는 댐퍼 클러치(Damper Clutch)가 적용된다.Therefore, in order to provide the convenience of the automatic transmission and the efficiency of the manual transmission, a damper clutch is provided to minimize the power loss by directly connecting the pump shaft and the turbine shaft of the torque converter together in a specific region, do.

댐퍼 클러치는 엔진회전수와 터빈회전수의 비가 통상적으로 0.6 ~ 0.7 이상이 되는 시점에서 작동되어 엔진의 출력을 직결시킴으로써 연비 향상을 제공한다.The damper clutch is operated at a time when the ratio between the engine speed and the turbine speed is normally 0.6 to 0.7 or more, thereby directly improving the fuel economy by directly connecting the output of the engine.

슬립 락업 제어는 댐퍼 클러치를 완전히 직결시키기 않고 30 ~ 50RPM 정도의 슬립을 유지시켜 엔진의 변동량이 터빈으로 전달되는 것을 저감시키는 기술이다.The slip-lock-up control is a technique that maintains a slip of about 30 to 50 RPM without directly connecting the damper clutch, thereby reducing the transmission of the fluctuation amount of the engine to the turbine.

종래의 자동변속기에 적용되어 있는 슬립 락업 제어는 엔진 회전수와 터빈 회전수를 검출하여 평균값을 산출하고, 엔진 회전수 및 터빈 회전수의 평균값에 따라 댐퍼 클러치의 유압을 제어하여 목표 슬립량을 추종시키는 방식이 적용된다.The slip lock-up control, which is applied to a conventional automatic transmission, calculates the average value by detecting the engine speed and the turbine speed, and controls the hydraulic pressure of the damper clutch according to the average value of the engine speed and the turbine speed to follow the target slip amount .

종래의 슬립 락업 제어는 엔진 회전수의 변동량을 포함해서 보면 슬립량이 충분하게 확보되지 못하여 엔진 회전수의 미소한 변동량이 터빈 회전수에 큰 간섭으로 발생되어 사실상 안정적인 슬립 락업 제어가 실행되지 못하는 단점이 있다.The conventional slip lock-up control has a disadvantage in that the slip amount can not be sufficiently secured when the fluctuation amount of the engine speed is included, so that a minute variation amount of the engine speed is generated due to large interference with the turbine speed, have.

따라서, 도 3에 도시된 바와 같이, 엔진 회전수의 변동량에 따라 슬립영역에서 큰 실내부밍을 발생시켜 NVH에 악영향을 초래하는 문제점이 있다.Accordingly, as shown in FIG. 3, large indoor wobbling is generated in the slip region in accordance with the fluctuation amount of the engine speed, which has a problem of adversely affecting the NVH.

또한, 토크 컨버터 내부에 있는 댐퍼 클러치의 내구성을 악화시키는 문제점이 있다.Further, the durability of the damper clutch in the torque converter is deteriorated.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로, 그 목적은 차량의 주행 상태에 따라 상시적으로 변화하는 엔진 회전수의 변동량을 고려하여 실시간 슬립 락업 제어가 실행되도록 함으로서, 연비, 댐퍼 클러치의 내구성, 구동계의 NVH 성능 향상을 극대화하도록 하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and its object is to provide a fuel injection control device and a control method thereof, which are capable of real-time slip lock-up control in consideration of a variation amount of engine speed, Durability, and NVH performance of the drive system.

상기한 목적을 실현하기 위한 본 발명의 특징에 따른 자동변속기의 슬립 락업 제어장치는, 엔진의 회전수를 검출하는 제1센서; 터빈의 회전수를 검출하는 제2센서; 상기 제1,2센서의 정보에서 엔진 회전수의 변동량과 터빈 회전수로부터 간섭 량을 계산하고, 계산된 간섭량과 목표 간섭량에 따라 댐퍼 클러치의 유압을 제어하여 슬립 락업 제어를 실행하는 제어부; 상기 제어부의 제어신호에 따라 작동되어 댐퍼 클러치 유압을 조정하는 액추에이터를 포함한다.To achieve the above object, according to an aspect of the present invention, there is provided a slip lock-up control apparatus for an automatic transmission, comprising: a first sensor for detecting the number of revolutions of an engine; A second sensor for detecting the number of revolutions of the turbine; A controller for calculating an interference amount from the engine speed variation and the turbine speed in the information of the first and second sensors and controlling the hydraulic pressure of the damper clutch in accordance with the calculated interference amount and the target interference amount; And an actuator that is operated in accordance with the control signal of the control unit to adjust the hydraulic pressure of the damper clutch.

또한, 본 발명의 특징에 따른 자동변속기의 슬립 락업 제어방법은, 댐퍼 클러치의 슬립 제어가 개시되면 엔진 회전수의 변동량과 터빈 회전수를 추출하여 엔진 회전수와 터빈 회전수간의 간섭량을 계산하는 과정; 상기 계산된 간섭량과 기 설정된 목표 간섭량을 비교하여 댐퍼 클러치에 공급되는 유압을 제어하는 과정; 댐퍼 클러치의 슬립 유압과 락업 유압이 일치하면 슬립 락업 제어의 종료로 판단하여 슬립 락업 유압을 초기화하는 과정을 포함한다.The slip lock-up control method for an automatic transmission according to the present invention further includes a step of calculating a variation amount of the engine speed and a turbine speed when the slip control of the damper clutch is started and calculating an amount of interference between the engine speed and the turbine speed ; Controlling the hydraulic pressure supplied to the damper clutch by comparing the calculated amount of interference with a predetermined target amount of interference; And when the slip hydraulic pressure of the damper clutch coincides with the lockup hydraulic pressure, it is determined that the slip lockup control is ended and the slip lockup hydraulic pressure is initialized.

아래에서는 첨부한 도면을 참고로 하여 본 발명의 실시예에 대하여 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 상세히 설명한다. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

본 발명은 여러 가지 상이한 형태로 구현될 수 있으므로 여기에서 설명하는 실시예에 한정되지 않으며, 도면에서 본 발명을 명확하게 설명하기 위해서 설명과 관계없는 부분은 생략하였다.The present invention may be embodied in many different forms and is not therefore limited to the embodiments described herein. For the sake of clarity, the present invention is not described herein.

도 1은 본 발명의 실시예에 따른 자동변속기의 슬립 락업 제어장치를 개략적으로 도시한 도면이다.1 is a schematic view of a slip lock-up control apparatus for an automatic transmission according to an embodiment of the present invention.

본 발명은 제1센서(101)와 제2센서(103), 제어부(105) 및 액추에이터(107)를 포함한다.The present invention includes a first sensor (101) and a second sensor (103), a control unit (105), and an actuator (107).

제1센서(101)는 마그네틱 픽업 센서로 이루어지며, 엔진의 회전수를 검출하여 그에 대한 정보를 제어부(105)에 제공한다.The first sensor 101 comprises a magnetic pickup sensor, detects the number of revolutions of the engine, and provides information on the number of revolutions of the engine to the control unit 105.

상기 제1센서(101)는 일 예를 들어 엔진측의 링기어에 설치된다.The first sensor 101 is installed, for example, on the engine-side ring gear.

제2센서(103)는 변속기에 장착되는 센서로, 터빈의 회전수를 검출하여 그에 대한 정보를 제어부(105)에 제공한다.The second sensor 103 is a sensor mounted on the transmission, detects the rotational speed of the turbine, and provides information on the detected rotational speed to the control unit 105.

제어부(105)는 엔진 회전수의 변동량과 터빈 회전수로부터 현재의 간섭량을 계산하고, 계산된 간섭량과 목표 간섭량을 비교하여 비교된 결과에 따라 댐퍼 클러치의 유압을 제어하여 목표 간섭량을 추종하도록 슬립 락업 제어를 실행한다.The control unit 105 calculates the current interference amount from the engine speed variation and the turbine speed, compares the calculated interference amount with the target interference amount, and controls the oil pressure of the damper clutch according to the comparison result to follow the target interference amount. Control is executed.

상기 간섭량은 슬립 락업 제어시에 엔진 회전수와 터빈 회전수가 얼마나 간섭되는지를 나타내는 물리량으로, 하기와 수학식 1을 적용하여 산출한다.The interference amount is a physical quantity indicating how much the engine speed and the turbine speed interfere with each other during the slip-up control, and is calculated by applying the following equation (1).

Figure 112014125959549-pat00005
간섭량(%) =
Figure 112014125959549-pat00005
Interference (%) =

상기 수학식에서, Tavg ; 터빈 회전수의 평균값, Eavg ; 엔진 회전수의 평균값, Emin ; 엔진 회전수의 최소값을 의미한다.In the above equation, T avg ; Average value of turbine rpm, E avg ; Average value of engine speed, E min ; Means the minimum value of the engine speed.

상기 Emin = Eavg - 엔진 회전수 변동량 / 2로 산출된다. E min = E avg - engine speed variation / 2.

상기의 수학식 1에서 터빈 회전수의 평균값이 엔진 회전수의 최소값 보다 작거나 같으면 음수 또는 간섭량이 "0%"가 되어 간섭량이 없기 때문에 엔진 회전수의 변동량이 터빈측으로 전달되지 않아 슬립 락업제어가 완벽하게 이루어진다.If the average value of the turbine rpm is equal to or smaller than the minimum value of the engine rpm, the negative or the interference amount becomes "0% ", so that the fluctuation amount of the engine rpm is not transmitted to the turbine side. Perfectly done.

그리고, 터빈 회전수의 평균값이 엔진 회전수의 최소값 보다 크고 엔진 회전수의 평균값 보다 작은 경우 간섭량이 "0 ~ 100%"의 범위에 존재하게 된다.If the average value of the turbine rpm is larger than the minimum value of the engine rpm and smaller than the average value of the engine rpm, the interference amount is in the range of "0 to 100% ".

또한, 터빈 회전수의 평균값과 엔진 회전수의 평균값이 동일한 경우 간섭량이 "100%"가 되어 직결된 상태이다.In addition, when the average value of the turbine rpm and the average value of the engine rpm are the same, the interference amount is "100%"

따라서, 하기의 표 1에서 알 수 있는 바와 같이, 슬립량이 동일하더라도 엔진 회전수의 변동량이 크면 간섭량이 커져 구동계에서 부밍 및 진동이 크게 발생하므로, 간섭량을 고려한 슬립 락업 제어가 요구됨을 알 수 있다.Therefore, as can be seen from the following Table 1, even if the slip amount is the same, if the fluctuation amount of the engine speed is large, the amount of interference becomes large, so that the driving system generates a large amount of booming and vibration, and slip lockup control considering the interference amount is required.

액추에이터(107)는 하나 이상의 솔레노이드 밸브로 구성되며, 상기 제어부(105)에서 인가되는 제어신호에 따라 동작되어 댐퍼 클러치에 공급되는 유압을 조정하여 댐퍼 클러치의 작동 및 작동 해제와 슬립 락업을 실행한다.The actuator 107 is constituted by at least one solenoid valve and is operated in accordance with a control signal applied from the control unit 105 to adjust the hydraulic pressure supplied to the damper clutch to perform the operation and the disengagement of the damper clutch and the slip lockup.

전술한 바와 같은 기능이 포함되는 구성의 본 발명에 따른 자동변속기에서 댐퍼 클러치를 제어하는 동작에 대하여 구체적으로 설명하면 다음과 같다.The operation of controlling the damper clutch in the automatic transmission according to the present invention having the above-described functions will be described in detail as follows.

자동변속기기 적용된 차량의 운행에서 댐퍼 클러치의 슬립 제어가 시작되면(S101) 제어부(105)는 제1센서(101) 및 제2센서(103)에서 출력되는 펄스신호를 취득한 다음(S102) 제1센서(101)의 펄스신호로부터 엔진 회전수의 변동량을 계산하고 제2센서(103)의 펄스신호로부터 터빈 회전수를 계산한다(S103).When the slip control of the damper clutch is started in operation of the vehicle to which the automatic transmission is applied (S101), the control unit 105 acquires the pulse signals output from the first sensor 101 and the second sensor 103 (S102) Calculates the variation amount of the engine speed from the pulse signal of the sensor 101 and calculates the turbine speed from the pulse signal of the second sensor 103 (S103).

이후, 전술한 수학식 1을 적용하여 엔진 회전수와 터빈 회전수 사이의 간섭량(%)을 계산한 다음 설정된 목표 간섭량(%)과 비교하여 계산된 간섭량(%)이 설정된 목표 간섭량(%)을 초과하는지를 판단한다(S105).Thereafter, the interference amount (%) between the engine revolution number and the turbine revolution number is calculated by applying the above-described equation (1), and then the interference amount (%) calculated by comparing with the set target interference amount% (S105).

상기 목표 간섭량(%)은 차종에 따라 각기 상이하게 결정되며, 예를 들어 직렬 4기동 2.0 엔진의 경우 목표 간섭량을 25% 이하로 설정한다.The target interference amount (%) is determined differently depending on the type of vehicle. For example, in the case of a serial 4-start 2.0 engine, the target interference amount is set to 25% or less.

상기 S105의 판단에서 계산된 현재의 간섭량(%)이 목표 간섭량(%)을 초과하지 않는 경우 엔진 회전수의 변동량이 터빈 회전수에 영향을 미치지 않는 조건인 것으로 판단하여 현재의 조건으로 목표 간섭량을 추종하는 슬립 락업 제어를 유지한다(S106).If the current interference amount (%) calculated at S105 does not exceed the target interference amount (%), it is determined that the fluctuation amount of the engine speed does not affect the turbine speed and the target interference amount And maintains the sleep-lock-up control that follows (S106).

그러나, 상기 S105의 판단에서 계산된 현재의 간섭량(%)이 목표 간섭량을 초과하는 경우 엔진 회전수의 변동량의 터빈 회전수에 영향을 초래하여 엔진 회전수의 변동량에 따라 구동계에서 부밍 및 진동을 발생시키는 조건인 것으로 판단하여 슬립량을 증대시키기 위한 제어신호를 액추에이터(107)에 출력한다(S107).However, if the current interference amount (%) calculated in the determination of S105 exceeds the target interference amount, it affects the turbine rotation number of the engine revolution number and causes the driving system to cause the boom and vibration in accordance with the variation amount of the engine revolution number And outputs a control signal for increasing the slip amount to the actuator 107 (S107).

따라서, 액추에이터(107)는 제어신호에 따라 작동되어 유압 감소를 실행시킴으로서 슬립량이 높게하여 간섭량이 낮아지도록 한다(S108).Accordingly, the actuator 107 is operated in accordance with the control signal to reduce the hydraulic pressure, thereby increasing the amount of slip to reduce the amount of interference (S108).

상기한 바와 같이 유압 감소의 실행에 따라 댐퍼 클러치에 공급되는 슬립 유압과 락업 유압이 일치되는지를 판단하여(S109) 두 유압이 서로 일치하지 않으면 상기 S102의 과정으로 리턴되어 전술한 과정을 반복하여 슬립 락업 제어를 유지한다.As described above, it is determined whether the slip oil pressure supplied to the damper clutch and the lockup oil pressure match with each other (S109). If the two oil pressures do not coincide with each other, the process returns to S102 and the above- Lock-up control is maintained.

그러나, 상기 S109의 판단에서 댐퍼 클러치에 공급되는 슬립 유압과 락업 유압이 서로 일치하면 슬립 락업의 종료로 판단한 다음(S110) 슬립 락업 유압을 초기화한다(S111).However, if the slip hydraulic pressure supplied to the damper clutch is equal to the lockup hydraulic pressure in step S109, it is determined that the slip lockup is terminated (S110) and the slip lockup hydraulic pressure is initialized (S111).
