It relates to a learning control device and a method of a transmission.

자동차 산업이 대량 양산 체제를 갖춘지 오래 되었지만, 아직 차량 마다의 하드웨어(H/W) 편차는 존재하고 있다. 이를 극복하기 위해 댐퍼클러치 개별 학습 로직(logic)을 적용하여 하드웨어 편차 극복을 위해 노력해왔으나, 운행 초기에 댐퍼 유압 편차 전체를 한 번에 학습시킬 수 있는 방법은 없다는 문제점을 지녀왔다.Although the automotive industry has been in mass production for a long time, hardware-to-vehicle (H / W) deviations still exist. In order to overcome this problem, efforts have been made to overcome the hardware deviation by applying the damper clutch individual learning logic, but there is a problem that there is no way to learn the entire damper hydraulic deviation at the same time at the beginning of operation.

본 발명의 다른 측면에 따르면, 자동변속기의 학습제어방법은 스로틀 구동시 변속기가 SD구간에 진입했는지 판단하는 제1 단계; 변속기가 일정구간에 진입한 경우, 일정기준 슬립량 도달후 일정 딜레이 타임진행후에 실제듀티를 저장하는 제2 단계; 학습 조건인 경우 실제 듀티와 정상 듀티의 편차값을 산출하는 제3 단계; 및 상기 제3 단계에서의 듀티 편차값을 편차 보정값으로 설정하여 학습하는 제4 단계를 포함하는 것을 특징으로 한다.According to another aspect of the present invention, the learning control method of the automatic transmission may include a first step of determining whether the transmission enters the SD section during throttle driving; A second step of, when the transmission enters a certain section, storing the actual duty after advancing a predetermined delay time after reaching a predetermined reference slip amount; Calculating a deviation value between the actual duty and the normal duty in the case of the learning condition; And a fourth step of learning by setting the duty deviation value in the third step as a deviation correction value.

이상 설명한 바와 같이, 본 발명에 따른 자동변속기의 학습제어방법에 의하면, 계산된 학습값을 댐퍼 전체 제어영역에 전파시킬 수 있어 응답성이 향상될 뿐만 아니라 파워/온(P/ON) 조건의 변이(transient)구간에서 상세 조건들을 충족시켰을 때에만 학습을 하여 학습 정확도를 높일 수 있으므로, 댐퍼 개별학습들만 실시했을 때에 비해 출고된 양산 차량 상태의 조기 안정화에 기여할 수 있는 효과가 있다.As described above, according to the learning control method of the automatic transmission according to the present invention, it is possible to propagate the calculated learning value to the entire damper control area, thereby improving response and changing power / on conditions.

따라서, 본 발명에 따른 장치 및 방법을 적용할 경우, 위와 같은 장점외에 차량마다 발생할 수 있는 양산 편차에도 조기 대응할 수 있는 효과가 있다.Therefore, when applying the apparatus and method according to the present invention, in addition to the above advantages there is an effect that can respond early to the mass production deviation that may occur for each vehicle.

상기 학습조건은 변속기의 유온 조건, 스로틀(악셀 페달)값, 차량 속도, 터빈 회전수, 슬립(엔진 회전수-터빈회전수), 구배 계산 값, 현재의 기어단 정보, 댐퍼 제어 타입, 포지션 레버 상태 중 적어도 하나 이상을 포함하는 것을 특징으로 한다.The learning conditions include the oil temperature condition of the transmission, the throttle (axel pedal) value, the vehicle speed, the turbine speed, the slip (engine speed-turbine speed), the gradient calculation value, the current gear stage information, the damper control type, the position lever. It characterized in that it comprises at least one or more of the states.

자동변속기가 일정구간 즉, SD 구간에 진입한 경우 상기 제어부(10)는 일정기준 슬립량에 도달하였는지 판단하고, 일정기준 슬립량에 도달한 경우에는 일정 딜레이 타임이 진행된 후에 실제 듀티값이 저장되도록 제어한다.When the automatic transmission enters a certain section, that is, the SD section, the controller 10 determines whether a certain reference slip amount is reached, and when the constant reference slip amount is reached, the actual duty value is stored after a predetermined delay time is progressed. To control.

도 2를 참조하면, 스로틀 구동시(S101), 제어부(10)는 변속기가 SD구간에 진입했는지 판단한다(S102).Referring to FIG. 2, during throttle driving (S101), the controller 10 determines whether the transmission enters the SD section (S102).

또한, 제어부(10)는 변속기가 일정구간에 진입한 경우, 일정기준 슬립량 도달후(S103) 일정 딜레이 타임진행후에(S104) 실제듀티값을 저장한다(S105).In addition, when the transmission enters a certain section, the control unit 10 stores the actual duty value after the constant delay time is reached (S103) and after a predetermined delay time (S104) (S105).

이후, 학습 조건인 경우 제어부(10)는 실제 듀티값과 정상 듀티값을 비교하여(S106), 두값의 편차값을 산출한다. 이후 제어부(10)는 비교후 산출된 듀티 편차값만큼 보정하는 과정을 수행하는데(S107), 즉, 산출된 듀티 편차값을 편차 보정값으로 설정하여 학습을 수행한다.Subsequently, in the case of the learning condition, the controller 10 compares the actual duty value with the normal duty value (S106) and calculates a deviation value between the two values. Thereafter, the controller 10 performs a process of correcting the calculated duty deviation value after the comparison (S107), that is, sets the calculated duty deviation value as the deviation correction value to perform the learning.

본 발명에서 학습을 진행하는 상기 일정구간은 SD구간이다.In the present invention, the predetermined section for learning is an SD section.

It characterized in that it comprises at least one or more of the states.

상기 학습조건을 좀 더 자세히 설명하면,If the above learning conditions are explained in more detail,

댐퍼 클러치 제어는 스로틀 온(ON)상태에서 일정 슬립(Slip)량(엔진 회전수-터빈 회전수)을 유지하여 제어하는 S구간, 스로틀 ON상태에서 엔진과 터빈이 완전직결되어 유지하는 D구간, 그리고 팁-아웃(Tip-out) 이후 스로틀 오프(OFF)상태에서 일정 슬립량을 유지하며 제어하는 C구간(도시안됨)으로 나뉘는데, 본 발명에서 새로 제안한 학습은 S구간과 D구간의 천이(transient) 영역인 SD구간에서 일정조건을 충족했을 때 수행되는 원리이며, 세부 충족조건은 다음과 같다.Damper clutch control consists of an S section that maintains and controls a certain amount of slip (engine speed-turbine speed) in the throttle ON state, and a D section that maintains the engine and the turbine in direct connection in the throttle ON state. And after tip-out is divided into a C section (not shown) that maintains and controls a certain amount of slip in the throttle off state, the newly proposed learning in the present invention is a transition between the S and D section (transient) This is the principle that is performed when certain conditions are met in the SD section.

도 3 및 도 4를 참조하면, 변속기의 학습구간은 S,SD,D으로 구분하여 표시하였다. 즉, S는 슬립구간이고, D는 완전 직결 구간이며 SD는 슬립구간에서 완전직결 구간으로 진행하는 중간구간으로서 본 발명에서 설정한 구간이다.Referring to Figures 3 and 4, the learning interval of the transmission is displayed by dividing the S, SD, D. That is, S is a slip section, D is a direct direct section, and SD is a section set in the present invention as an intermediate section proceeding from a slip section to a full direct section.

S상태에서 SD영역 진입 후 일정기준 슬립량에 도달하면, 이 시점부터 일정 딜레이 시간동안 기다리고 이 딜레이 시간이 지난 시점의 제어 듀티를 저장하게 되며, 이 저장된 실제 듀티값과 기존에 이미 설정해 놓은 정상 상황시의 제어듀티와의 차이를 비교하여 그 만큼의 차이를 보정해주는 구조이다. 이때 딜레이 시간을 설정한 이유는 기준 슬립량에 도달한 이후 일지라도 얼마 지나지 않아 하드웨어 문제등으로 인한 슬립량의 급상승 등을 사전에 대비함으로써 진정한 제어 안정구간의 제어듀티값을 산출하기 위함이다.If the standard slip amount is reached after entering the SD area in S state, it waits for a certain delay time from this point and stores the control duty at the time after this delay time, and the stored actual duty value and the normal situation already set It compares the difference with the control duty of the city and corrects the difference. At this time, the reason for setting the delay time is to calculate the control duty value of the true control stability section by preparing for the sudden increase in the slip amount due to hardware problems, even after the reference slip amount is reached.
