Description

자동 변속기의 초기 필 타임 학습 제어방법{METHOD FOR LEARNING INITIAL FILL-TIME IN AUTOMATIC TRANSMISSION}How to control the initial fill time learning of an automatic transmission {METHOD FOR LEARNING INITIAL FILL-TIME IN AUTOMATIC TRANSMISSION}

본 발명은 자동차의 자동 변속기에 관한 것으로써, 특히 자동 변속기의 변속감을 개선하기 위한 초기 필 타임 학습 제어방법에 관한 것이다.The present invention relates to an automatic transmission of an automobile, and more particularly, to an initial fill time learning control method for improving a transmission feeling of an automatic transmission.

일반적으로. 자동 변속기가 장착되어 있는 자동차는 운행 중 출력되는 운행 정보에 따라 변속단을 목표 변속단으로 변속하기 위한 제어신호를 구동 수단인 솔레노이드 밸브에 출력하여 유압회로를 구성한다.Generally. A vehicle equipped with an automatic transmission configures a hydraulic circuit by outputting a control signal for shifting a shift stage to a target shift stage according to driving information output during driving, to a solenoid valve as a driving means.

상기에서 구성된 유압회로에 의해 마찰요소인 클러치 및 브레이크 등을 결합 및 해방시켜가며 목표하는 변속단으로의 변속을 수행하는 자동 변속기는 토크 컨버터를 걸쳐 입력된 엔진의 동력을 유성치차와 드리븐 기어를 걸쳐 바퀴에 전달한다.The automatic transmission that engages and releases the friction elements such as clutches and brakes by the hydraulic circuit configured as described above and shifts to a target shift stage is applied to the engine power input through the torque converter, through the planetary gear and driven gear. Pass on the wheels.

상기와 같이 동작하는 자동 변속기에서, 종래에는 파워 온 업 쉬프트 변속 중 해방측 압력 저하에 의해 유압 형성이 지연되어 짧은 시간동안 일정 주기로 듀티값이 0%에서 100%로 가변(이하 방방(bang bang)제어 듀티라 칭함)되어 발생하면 결합측에서 방방 제어 듀티가 최종적으로 오프되는 시점까지의 시간을 검출하여 해방측의 초기 필 타임(tF)를 보정하였다.In the automatic transmission operating as described above, conventionally, the hydraulic pressure is delayed due to the release pressure drop during power-up shift shifting, and the duty value is varied from 0% to 100% in a fixed period for a short time (hereinafter referred to as bang bang). When generated and referred to as a control duty, the time from the coupling side to the time when the release control duty is finally turned off is detected to correct the initial fill time tF on the release side.

상기 초기 필 타임 학습에 의해 방방 제어가 발생하지 않을 때에는 초기 필 타임을 일정량 감산함에 따라 런 업(Run Up)을 유도하고, 런 업 발생후 다시 트래킹에 의한 클러치 피스톤 스트로크 학습 제어에 의해 계산된 값을 필 타임에 가산하여 필 타임을 증가시키는 루프를 반복하고 있다.When the directional control does not occur by the initial fill time learning, a run up is induced by subtracting the initial fill time by a predetermined amount, and the value calculated by the clutch piston stroke learning control by tracking again after the run up occurs. We repeat the loop that adds to the fill time and increases the fill time.

그런데, 이러한 학습 제어를 계속 진행하면 방방 제어는 항상 발생할 수 있으며, 자동 변속기의 유압 특성이 항상 일정하지 않아 방방 제어 시에 간혹 런 업량이 크게 발생하여 변속감이 불량해 지는 경우가 발생한다.However, if the learning control continues, the directional control may always occur, and the hydraulic characteristic of the automatic transmission is not always constant, and thus a large amount of run-up occurs at the time of directional control, resulting in poor transmission feeling.

이와 같은 문제점을 해결하기 위해, 본 발명이 이루고자 하는 기술적인 과제는 초기 필 타임을 일정량 감산하지 않고 초기 필 타임과 결합측 솔레노이드의 듀티율을 이용하여 결합측 요소의 제어시간을 조정하고, 이를 이용하여 변속감을 개선할 수 있는 필 타임 학습 제어방법을 제공하고자 하는 데 그 목적이 있다.In order to solve this problem, the technical problem to be achieved by the present invention is to adjust the control time of the coupling element by using the initial fill time and the duty ratio of the coupling solenoid without subtracting the initial fill time by a certain amount, The purpose of the present invention is to provide a fill-time learning control method for improving the shifting feeling.

도1은 본 발명의 실시예에 따른 자동 변속기의 초기 필 타임 학습 제어장치를 나타내는 구성 블록도이다.1 is a block diagram illustrating an initial fill time learning control apparatus of an automatic transmission according to an exemplary embodiment of the present invention.

첨부한 도1에서와 같이, 본 발명의 실시예에 따른 자동 변속기의 초기 필 타임 학습 제어장치는, 차량의 주행 상태에 따라 가변되어 출력되는 신호를 감지하여 해당하는 전기 신호로 출력하는 차량주행 감지수단(100); 차량주행 감지수단(100)에서 출력되는 전기 신호를 수신하여 판독하고, 판독에 의한 방방 제어 듀티가 출력되면 방방 제어가 발생된 것으로 판단하여 결합측 유압 제어 구간의 제어시간이목표 시간보다 작은지를 점검하고, 결합측 유압 제어 구간의 제어시간이 목표 시간보다 작으면 초기 필 타임을 감산하여 보정하는 제어부(200); 제어부(200)에서 출력되는 변속 듀티 제어신호를 인가 받아 파워 온 2->3, 3->4 업 쉬프트 변속을 수행하는 구동부(300)를 포함하여 이루어진다.As shown in FIG. 1, the initial fill time learning control apparatus of an automatic transmission according to an exemplary embodiment of the present invention detects a vehicle driving that detects a signal that is varied and output according to a driving state of a vehicle and outputs the corresponding electric signal. Means (100); Receives and reads an electric signal output from the vehicle driving detecting means 100, and if the control control output by the output is output, it is determined that the control is generated to check whether the control time of the coupling-side hydraulic control section is less than the target time And a controller 200 which subtracts and corrects an initial fill time when the control time of the coupling-side hydraulic control section is smaller than the target time; The driving unit 300 is configured to receive a shift duty control signal output from the controller 200 and perform power-on 2-> 3, 3-> 4 upshift shifting.

차량주행 감지수단(100)은, 가속 페달의 동작 상태에 연동하여 개폐 상태가 가변되는 스로틀 밸브의 개도 정도를 감지하여 해당 신호를 출력하는 스로틀 밸브 개도량 감지부(110); 차량의 출력축 회전수를 감지하여 차량의 주행속도에 대응하는 해당 신호를 출력하는 차속 감지부(120); 스로틀 밸브 개도량과 차속에 따라 변속단이 가변되면, 변속단의 가변 상태를 감지하여 해당 신호를 출력하는 변속단 감지부(130); 변속기의 입력축과 연결되어 있는 토오크 컨버터의 터빈축 회전속도를 감지하여 해당하는 신호를 출력하는 터빈 회전수 감지부(140); 엔진의 동작 상태에 따라 가변되는 크랭크 축의 회전 속도를 검출하여 해당 신호를 출력하는 엔진 회전수 감지부(150)를 포함하여 이루어진다.The vehicle driving detecting means 100 includes: a throttle valve opening amount detecting unit 110 for detecting an opening degree of a throttle valve whose opening / closing state is variable in association with an operation state of an accelerator pedal and outputting a corresponding signal; A vehicle speed detecting unit 120 for detecting an output shaft rotation speed of the vehicle and outputting a corresponding signal corresponding to the traveling speed of the vehicle; A shift stage detecting unit 130 configured to detect a variable state of the shift stage and output a corresponding signal when the shift stage is changed according to the throttle valve opening amount and the vehicle speed; A turbine rotation speed sensing unit 140 for detecting a turbine shaft rotation speed of a torque converter connected to an input shaft of a transmission and outputting a corresponding signal; It includes the engine speed detection unit 150 for detecting the rotational speed of the crankshaft variable according to the operating state of the engine and outputs a corresponding signal.

상기한 구성에 의해 이루어진 자동 변속기의 파워 온 2->3, 3->4 결합측 초기 필 타임 학습 제어방법에 대하여 첨부한 도면을 참조하여 상세히 설명한다.With reference to the accompanying drawings, the power on 2-> 3, 3-> 4 coupling side initial fill time learning control method of the automatic transmission made by the above-described configuration will be described in detail.

배터리 접속 후(S100), 파워 온 2->3, 3->4 업 쉬프트의 초기 필 타임 학습 제어가 허가되고(S110), 운행 중 제어부(200)에서 변속단을 목표 변속단으로 변속하기 위한 파워 온 2->3,3->4 업 쉬프트 변속 제어 신호가 출력되어 변속단을 목표 변속단으로 변속하던 중 상기의 제어부(200)는 해방측 유압의 저하로 인한 변속이 지연되어 첨부한 도2에서와 같이 방방 제어 듀티가 온 되었는지를 판단한다(S120).After the battery is connected (S100), the initial fill time learning control of the power-on 2-> 3, 3-> 4 upshift is permitted (S110), and the control unit 200 shifts the shift stage to the target shift stage during operation. While the power-on 2-> 3,3-> 4 upshift shift control signal is output and the shift stage is shifted to the target shift stage, the controller 200 delays the shift due to the lowering of the hydraulic pressure on the released side. As shown in 2, it is determined whether the controlled release duty is turned on (S120).

방방 제어 듀티가 온 되었으면, 초기 필 타임 종료 검출점에서의 스트로크 값 Sct와 전 회까지의 스트로크 값의 차로부터 새로운 스트로크 보정량 (Scl)new을 하기의 수학식 1로 결정한다.When the directional control duty is turned on, a new stroke correction amount Scl is determined from Equation 1 below from the difference between the stroke value Sct at the initial fill time end detection point and the stroke value up to the previous time.

ΔSct = Sct + ΔSclb - {(Scl)old + Sc}ΔSct = Sct + ΔSclb-{(Scl) old + Sc}

ΔSct : 스트로크 편차량ΔSct: stroke deviation

Sct : 스트로크 트래킹에 의한 스트로크량Sct: Stroke amount by stroke tracking

ΔSclb : 파워 온 업 쉬프트 방방 제어 발생시 가산량ΔSclb: Addition amount when power-on-up shift control is generated

(Scl)old : 전 회까지의 스트로크 학습 보정량(Scl) old: stroke learning correction amount up to the previous time

Sc : 스트로크의 베이스 값Sc: Base value of stroke

이 때, ΔScl(Scl의 보정량)을 상기한 ΔSct의 값에 대한 도3의 그래프로부터 결정한다. 그리고, 하기한 수학식 2로부터 새로운 보정량을 계산한다(S130).At this time, ΔScl (correction amount of Scl) is determined from the graph of FIG. 3 with respect to the value of ΔSct described above. Then, a new correction amount is calculated from Equation 2 (S130).

(Scl)new = (Scl)old + ΔScl(Scl) new = (Scl) old + ΔScl

도2는 본 발명의 실시예에 따른 자동 변속기의 변속 제어 개념도이다.2 is a conceptual diagram of shift control of an automatic transmission according to an exemplary embodiment of the present invention.

첨부한 도2에서와 같이, 방방이 발생하지 않으면서도 초기 터빈 변화율이 급격하게 변하지 않음을 인식할 수 있는 지시기(Indicator)를 통해 초기 터빈 변화율에 대한 업 쉬프트 제어 개념도에서 B구간을 사용한다. B구간 시간은 초기 필 타임 tF과 B구간의 듀티 DA1에 의해 결정된다. 필 타임이나 B구간 초기 듀티가 큰 값을 갖게되면, B구간 시간은 짧아지고, SB 점 부근에서의 초기 터빈 변화율도 급격하게변하는 경향이 있다. 필 타임이나 B구간 초기 듀티가 적은 값을 갖게되면 B구간 시간을 길어지고, SB 점 부근의 초기 터빈 변화율도 적은 값을 가지는 경향이 있다.As shown in FIG. 2, the section B is used in the upshift control concept diagram for the initial turbine change rate through an indicator that can recognize that the initial turbine change rate does not change rapidly without the occurrence of a room. Section B time is determined by duty DA1 of initial fill time tF and section B. If the fill time and the initial duty of section B have a large value, the section B time becomes shorter, and the initial turbine change rate near the SB point also tends to change rapidly. When the fill time and the initial duty of the section B have a small value, the section B time is lengthened, and the initial turbine change rate near the SB point also tends to have a small value.

그러므로, 방방 제어의 SOL 온 조건이 성립하지 않으면 B구간 시간이 목표 시간보다 적은지를 판단하고(S140), 이에 따라 방방 제어가 발생하기 이전까지 하기와 같은 수학식 3에 의해 초기 필 타임에 대한 감산 학습 제어를 수행한다(S150).Therefore, if the SOL on condition of the room control does not hold, it is determined whether the section B time is less than the target time (S140), and accordingly, the initial fill time is subtracted by Equation 3 below until the room control occurs. Learning control is performed (S150).

Scl = Scl - 임의의 설정값Scl = Scl-any setting

상기한 초기 필 타임의 임의의 설정값 감산 이후에는 Scl + Sc의 값이 0이 되지 않도록 하여 상기한 설정값을 계속해서 감산한다.After subtracting any set value of the initial fill time, the set value is continuously subtracted so that the value of Scl + Sc does not become zero.

배터리 접속 후 초기 필 타임의 학습 제어가 허가됨과 동시에 일단 방방 제어가 발생하고, 이후 방방 제어가 발생하지 않게 될 때 도3의 그래프의 ΔScl = 0이 되는 영역폭을 변경하고, 학습 1회당의 ΔScl의 의 최대량을 변경한다. 이 때, 배터리 접속 후 첫 번째 학습을 할 때까지는 Scl을 0으로 한다.After the battery is connected, the initial fill time learning control is permitted, and once the release control occurs and the release control does not occur afterwards, the area width where ΔScl = 0 in the graph of FIG. 3 is changed, and ΔScl per study Change the maximum amount of. At this time, Scl is set to 0 until the first learning after the battery is connected.

본 발명의 실시예는 하나의 실시예에 지나지 않으며, 본 발명의 요지를 벗어나지 않는 범위 내에서 변속감 개선을 위한 수식에는 많은 변형 및 변경이 가능함은 물론이며, 본 발명이 실시예에만 한정되는 것은 아니다.Embodiment of the present invention is only one embodiment, many modifications and variations are possible to the formula for improving the feeling of shift within the scope not departing from the gist of the present invention, of course, the present invention is not limited only to the embodiment. .

이상에서와 같이 본 발명의 자동 변속기의 초기 필 타임 학습 제어방법은 초기 필 타임을 일정량 감산하지 않고 초기 필 타임과 결합측 솔레노이드의 듀티율을이용하여 결합측 요소의 제어시간을 조정하고, 이를 이용하여 변속감을 개선할 수 있도록 한다.As described above, the initial fill time learning control method of the automatic transmission according to the present invention adjusts the control time of the coupling element by using the initial fill time and the duty ratio of the coupling solenoid without subtracting the initial fill time by a certain amount, and using the same. It helps improve the feeling of shifting.
