본 발명은 스태틱 변속중 응답지연시 강제학습방법에 관한 것으로서, 더욱 상세하게는 SS점~SB점, SB점~SF점 구간에서 변속시간이 제한시간을 초과한 경우 기설정한 듀티 경사를 발생시켜 강제 학습을 수행하고 이 강제 학습치를 갱신하여 동일한 변속감을 유지할 수 있도록 하는 강제 학습방법에 관한 것이다.The present invention relates to a forced learning method for response delay during static shifting. More specifically, when the shifting time exceeds a time limit in the SS point to SB point and SB point to SF point, a preset duty slope is generated. The present invention relates to a forced learning method for performing forced learning and updating this forced learning value so as to maintain the same shift feeling.

일반적으로 자동변속기 차량은 N→D, N→R 변속과 같은 스태틱 변속으로 전진 또는 후진 출발을 하게 된다.In general, automatic transmission vehicles start forward or reverse with static shifts such as N → D and N → R shifts.

따라서 이 스태틱 변속 제어는 자동변속기에 있어서 중요한 제어 부분을 차지하고 있다.Therefore, this static shift control is an important control part of the automatic transmission.

상기 스태틱 변속시 듀티 제어는, 소정의 필타임(Fill Time)이 지난 후 듀티(Duty)를 가하고, 변속 시작점(SB)이 검출되면 듀티를 점프량으로 감압시켜 변속감을 확보하도록 이루어져 있다.The duty control during the static shift is configured to apply a duty after a predetermined fill time, and to reduce the duty by a jump amount when the shift start point SB is detected, thereby securing a shift feeling.

이러한 스태틱 변속은 운전자들이 변속기의 신뢰성을 결정하는 중요한 변속으로서, 응답성과 변속 충격을 동시에 만족시켜야 하는 어려움을 가지고 있다.Such a static shift is an important shift in determining the reliability of the transmission, and has a difficulty in satisfying both response and shift shock.

그리고 대부분은 엔진 회전이 1000rpm 이하의 영역이고, 변속기 오일이 콜드 상태에서 스태틱 변속이 이루어짐에 따라 오일펌프에서 생성되는 유압의 편차로 인하여 그 제어가 어렵다.In most cases, the engine rotation is less than 1000rpm, and the control is difficult due to the variation in the hydraulic pressure generated by the oil pump as the static shift is performed while the transmission oil is cold.

그래서, 대부분은 통상적인 학습 기능을 두어 그 편차를 만족시키고 있으며, 어느 정도 원하는 성능을 발휘하고 있는 것도 사실이다.Therefore, most of them have a normal learning function to satisfy the deviation, and it is true that the desired performance is achieved to some extent.

그러나 종래의 통상적인 학습 기능으로는 자동차별 품질 편차 또는 내구 진행에 따른 유압 저하로 스태틱 변속시 변속이 지연될 경우 이를 보완하지 못하여 설정된 제한시간 내에 제어가 종료되지 않으면 강한 쇼크(shock)를 유발하며 변속을 강제로 종료한다.However, in the conventional learning function, if the shift is delayed during the static shift due to the quality deviation of each vehicle or the hydraulic drop due to the durability, the control cannot be compensated and the control is not terminated within the set time limit. This causes a strong shock and forces the shift to end.

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 품질 편차나 내구 진행에 따른 유압 저하가 발생한 경우에도 동일한 변속감을 유지하고 이를 보정할 수 있는 학습 방법을 제공할 수 있는 스태틱 변속중 응답지연시 강제 학습방법을 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-described problems, the static delay response response during shifting that can provide a learning method that can maintain the same shift feeling and correct it even when the hydraulic pressure drop due to quality deviation or durability progression occurs The purpose is to provide a compulsory learning method.

상술한 목적을 달성하기 위한 본 발명의 실시예에 따른 스태틱 변속중 응답지연시 강제 학습방법은, 자동변속기 차량의 N→D, N→R 변속과 같은 스태틱 변속중 변속구간을 SS점~SB점, SB점~SF점으로 나누어 각 구간의 변속시간을 측정하는 단계와, 상기 측정된 변속시간을 기설정된 제한시간과 비교하여 제한시간을 초과하는지 판단하는 단계와, 상기 변속시간이 제한시간을 초과하는 경우에 강제 유압제어로 기설정한 듀티 경사를 발생하여 강제 학습을 수행하는 단계와, 상기 제어가 완료된 후 강제 학습치를 갱신하는 단계를 포함한다.According to an embodiment of the present invention, a forced learning method for response delay during static shifting may include an SS point to an SB point during a shift period during static shifting such as N → D and N → R shifts of an automatic transmission vehicle. Measuring the shift time of each section by dividing the SB point to the SF point; comparing the measured shift time with a preset time limit and determining whether the time limit is exceeded; and the shift time exceeds the time limit. In this case, a step of generating a duty gradient preset by forced hydraulic control to perform forced learning, and updating the forced learning value after the control is completed.

이하 본 발명의 실시예에 대하여 첨부된 도면을 참고로 그 구성 및 작용을 설명하기로 한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

여기서 강제 학습치란 제한시간 이내에 변속이 완료되지 않은 경우 강제로 일정 제어압을 상승시켜 제한시간 이내로 변속이 되게 하는 제어값이다.
In the present invention, the manual select signal point (SS point) to the actual shift start point (SB point), the actual shift start point (SB point) to the shift end point (SF point) in order to prevent the delay phenomenon during N-> D and N-> R shifts. ) Set the appropriate shift limit time in the section and if the shift time exceeds the limit time, generate a preset duty slope to perform forced learning and update this forced learning value.
Here, the forced learning value is a control value forcibly raising the predetermined control pressure to shift within the time limit when the shift is not completed within the time limit.

또한, 제어 최종종료점(SE점)에서 재동기를 판정하여 동기 어긋남이 검출된 경우 램프 제어를 통해 변속감을 확보하고 강제로 학습치를 변경하여 차회에 동일한 조건의 제어시 제어성을 개선한다.
상기 재동기는 터빈 RPM이 목표치에 도달했는지 확인하는 과정이다.
In addition, when a synchronization deviation is detected by determining resynchronization at the control end point (SE point), a sense of shift is secured through ramp control, and the learning value is forcibly changed to improve controllability when controlling the same condition next time.
The resynchronization is a process of checking whether the turbine RPM has reached the target value.

N->D 변속중 측정된 변속시간이(S302) 제한시간(tsaot_ESL)인 400ms를 초과하여 지연된 경우에(S304), 강제 유압 제어로 기설정한 듀티 경사(hdbgt_secSlip_G1)를 31%/sec를 발생하여 강제(Security 2) 학습을 수행하고(S306), 상기 제어가 완료되면 듀티 학습치를 +3.125% 강제 갱신한다(S308).When the shift time measured during N-> D shifting is delayed by exceeding 400 ms which is the time limit tsaot_ESL (S302) (S304), 31% / sec of the duty ramp (hdbgt_secSlip_G1) preset by the forced hydraulic control is generated. By performing a forced (Security 2) learning (S306), and when the control is completed, the duty learning value is forced to update + 3.125% (S308).

그리고 N->R 변속중 측정된 변속시간이(S302) 제한시간(tsaot_ESL)인 900ms를 초과하여 지연된 경우에(S305), 강제 유압 제어로 기설정한 듀티 경사(hdbgt_secSlip_G1)를 31%/sec를 발생하여 강제(Security 2) 학습을 수행하고(S306), 상기 제어가 완료되면 듀티 학습치를 +3.125% 강제 갱신한다(S308).When the shift time measured during the N-> R shift is delayed by more than 900 ms which is the time limit tsaot_ESL (S305), the duty ramp preset by the forced hydraulic control (hdbgt_secSlip_G1) is 31% / sec.

도 4는 본 발명에 따른 SE점 이후 구간에서 강제 학습방법의 순서도이다.Figure 4 is a flow chart of the forced learning method in the section after the SE point in accordance with the present invention.

이와 같이 하여 강제(Security 1, Security 2) 학습을 수행한 후, 제어 최종종료 점(SE점)에서 재동기를 판정하여 동기 어긋남(60ms)이 발생하면(S402), 정속단으로 변속과정을 이행한 다음(S404), 정속단에서의 제어압으로 상승시키지 않고 기존에 진행되고 있던 제어압을 유지한 상태에서 램프(Ramp) 제어를 통해 강제로 설정한 듀티 경사의 기울기를 상승시켜 강제(Security 3) 학습을 수행하고(S406), 변속감을 확보한다.
여기서 듀티 경사의 기울기를 상승시킨다는 것은 제어 유압을 빠르게 한다는 의미이다.
After performing the forced (Security 1, Security 2) learning in this way, if the synchronous deviation (60ms) occurs by determining the resynchronization at the control end point (SE point) (S402), the shifting process is carried out to the constant speed stage. Then (S404), by increasing the inclination of the duty gradient set by force through the ramp control in the state of maintaining the control pressure that has been in progress, instead of increasing the control pressure at the constant speed stage (Security 3 ) To perform the learning (S406), to secure a sense of shifting.
Increasing the slope of the duty ramp here means to speed up the control hydraulic pressure.

이때 상기 듀티 경사의 기울기는 도 1에서 터빈 회전수 곡선 그래프와 듀티 그래프 곡선을 통해 설정한다.At this time, the slope of the duty gradient is set through the turbine speed curve graph and the duty graph curve in FIG.

이후 변속을 종료한(S408) 후, 듀티 학습치((hdb_DelAdp_ReOverrun)를 +1.5%만큼 강제 갱신한다(S410).After the shift is finished (S408), the duty learning value (hdb_DelAdp_ReOverrun) is forcibly updated by + 1.5% (S410).

상기 S402단계에서 재동기를 판정하여 동기가 어긋나지 않으면 통상적인 변속 과정을 수행한다(S422).If it is determined in step S402 that the resynchronization is not synchronized, a normal shifting process is performed (S422).

이와 같은 순서도에서 상기 강제 학습치가 더해질 때 기존에 통상적인 학습조건은 무시되며 동시 학습을 수행하지 않기 위해 강제 학습치를 레이블(Label)화 한다.In this flowchart, when the forced learning value is added, the conventional learning condition is ignored and the forced learning value is labeled so as not to perform concurrent learning.

또한, 학습치 적용 우선순위는 Security 1 학습, Security 2 학습 > 통상적인 학습 > Security 3 이고, 위의 우선 순위대로 학습치가 갱신되며 학습치는 중복 적용되지 않는다.In addition, the priority applied to the learning value is Security 1 learning, Security 2 learning> normal learning> Security 3, and the learning value is updated according to the above priority, and the learning value is not applied repeatedly.

이상에서 살펴본 바와 같이 본 발명에 의하며, 품질 편차나 내구 진행에 따른 유압 저하가 발생한 경우에도 동일한 변속감을 유지하고 이를 보정할 수 있는 학습 방법을 제공한다.As described above, the present invention provides a learning method capable of maintaining and correcting the same shift feeling even when a hydraulic pressure drop occurs due to quality deviation or durability.
