Description

경차용 자동변속기 변속단 제어장치Light transmission automatic gear shift controller

이 발명은 경차용 자동변속기 변속단 제어장치에 관한 것으로, 더욱 상세하게 말하자면, 스로틀 개도의 구간을 미리 정함으로써 변속 패턴으로부터 차기 변속단 결정 처리시간을 빠르게 하는 경차용 자동변속기 변속단 제어장치에 관한 것이다.The present invention relates to an automatic transmission shift stage control device for a light vehicle, and more particularly, to an automatic transmission shift control device for a light vehicle that speeds up the next shift stage determination processing time from a shift pattern by determining a section of a throttle opening degree in advance. will be.

최근, 토크 컨버터(torque converter) 및 유성기어(planetary gear unit)와 그, 제어유닛(control unit)이 조합되는 자동변속기는 변속 레버 변속시의 번거로움 감소, 원활한 가감속, 저속 발진성능 우수, 향상된 승차감 등의 장점으로 크게 각광받고 있다.Recently, an automatic transmission in which a torque converter and a planetary gear unit and a control unit are combined has reduced the hassle when shifting the shift lever, smooth acceleration and deceleration, excellent low speed oscillation performance, and improved performance. It is attracting much attention due to its advantages such as ride comfort.

종래에는 변속 패턴을 기준으로 하여 현 스로틀 개도에 따른 변속선을 가로 지르기의 여부를 결정하기 위하여 차속에 대하여 인터폴레이션(Interpolation)하는 시간이 더 필요하였다.Conventionally, in order to determine whether or not to cross the shift line according to the current throttle opening degree based on the shift pattern, a time for interpolation with respect to the vehicle speed was further required.

이하, 첨부된 도면을 참고로 하여 종래의 기술에 관하여 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described with respect to the prior art.

도3은 종래의 변속 패턴을 나타낸 그래프이다.3 is a graph showing a conventional shift pattern.

도3에 도시된바와 같이, 종래의 제어 방식은 변속 패턴을 기준으로 현재의 스로틀값을 입력 센서로부터 감지하여 현재의 변속단 좌, 우측에 있는 변속 변경선을 통과하였는지 판단하게 된다.As shown in FIG. 3, the conventional control method detects a current throttle value from an input sensor based on a shift pattern, and determines whether the current shift stage has passed a shift change line at left and right sides of the current shift stage.

이때 변속 변경선을 통과한 경우에는 변속을 실시하게 된다.In this case, when the transmission shift line passes, the shift is performed.

종래의 변속 제어 방식은 변속 변경선에 비교할 때에 현재 스로틀 입력값의 위, 아래 샘플값에 대한 차속 값을 읽어 내어 두값의 인터폴레이션을 시행함으로써 변속 변경선 통과 여부를 결정하는데, 이와 같이 행하는 데는 변속 여부를 결정하기 위하여 많은 시간이 소요되는 단점이 있다.The conventional shift control method reads the vehicle speed values for the upper and lower sample values of the current throttle input value and performs the interpolation of two values when comparing the shift change line to determine whether the shift change line passes. There is a disadvantage that takes a lot of time to do.

그러므로 본 발명의 목적은 종래의 단점을 해결하고자 하는 것으로, 스로틀 개도의 구간을 미리 정함으로써 변속 패턴으로부터 차기 변속단 결정 처리시간을 빠르게 하는 경차용 자동변속기 변속단 제어장치를 제공하고자 하는 것이다.It is therefore an object of the present invention to solve the disadvantages of the prior art, and to provide an automatic transmission shift stage control device for a light vehicle that speeds up the next shift stage determination processing time from the shift pattern by pre-determining a section of the throttle opening degree.

도1에 도시되어 있듯이, 이 발명의 실시예에 따른 경차용 자동변속기 변속단 제어장치의 구성은,As shown in Fig. 1, the configuration of an automatic transmission shift stage control apparatus for a light vehicle according to an embodiment of the present invention is

스로틀 개도를 감지하는 스로틀 개도 센서(1)와;A throttle opening sensor 1 for detecting a throttle opening;

차량의 속도를 감지하기 위한 속도 센서(2)와;A speed sensor 2 for detecting a speed of the vehicle;

상기 스로틀 개도 센서(1), 속도 센서(2) 및 인히비터 스위치(3)의 출력을 입력받아, 스로틀 개도의 구간을 미리 정함으로써 변속 패턴으로부터 차기 변속단 결정 처리시간을 빠르게 하는 변속제어유닛(4)과;A shift control unit that receives the outputs of the throttle opening degree sensor 1, the speed sensor 2, and the inhibitor switch 3, and sets a section of the throttle opening degree in advance to speed up the next shift stage determination processing time from the shifting pattern ( 4) and;

상기 변속제어유닛(4)의 출력을 입력받아 변속을 하는 솔레노이드 밸브(5)로 이루어진다.It consists of a solenoid valve (5) for shifting the input of the output of the shift control unit (4).

상기 구성에 의한 이 발명의 실시예에 따른 경차용 자동변속기 변속단 제어장치의 작용은 다음과 같다.The operation of the automatic transmission shift stage control device for a light vehicle according to the embodiment of the present invention by the above configuration is as follows.

먼저, 사용자에 의해 전원이 인가되면, 이 발명의 실시예에 따른 경차용 자동변속기 변속단 제어장치의 동작이 시작된다.First, when power is applied by the user, the operation of the automatic transmission shift stage control apparatus for a light vehicle according to the embodiment of the present invention is started.

동작이 시작되면, 스로틀 개도 센서(1), 속도 센서(2) 및 인히비터 스위치(3)로부터 스로틀 개도, 차량의 속도 및 현재의 변속단이 변속제어유닛(4)으로 입력된다.When the operation is started, the throttle opening degree, the speed of the vehicle and the current shift stage are input from the throttle opening degree sensor 1, the speed sensor 2 and the inhibitor switch 3 to the shift control unit 4.

그러면, 변속제어유닛(4)은 다음과 같은 방법으로 변속을 제어한다.Then, the shift control unit 4 controls the shift in the following manner.

먼저, 스로틀의 구간 등분시에 스로틀 개도 전범위에 대하여 N개로 등분하는 방법을 이용한다. 이렇게 하여 기존의 맵 테이블의 형태를 변경한다.First, a method of dividing the throttle opening degree into N pieces for the entire range at the time of sectional division of the throttle is used. This changes the shape of the existing map table.

즉, 위의 표와 같이, 스로틀의 전개도 범위를 N등분하고 각 구간마다 세타값(θ1 ~ θ12)으로써 표시한다.That is, as shown in the above table, the development range of the throttle is divided into N and displayed as theta values (θ1 to θ12) for each section.

우선적으로 현재의 스로틀 입력값이 N등분된 구간중에 어느 구간에 속하는지 상기 패턴(PATTERN표)에 의하여 결정한 후 현재의 차속 계산결과 값을 변속 패턴(도2)에서 비교하면, 각 구간별 비례배분의 계산결과를 하지 않고, 스로틀 개도에 따른 변속단을 바로 비교하여 변속 이행 여부를 결정할 수 있다. 이때의 변속 패턴을 도2에 도시하였다.If the current throttle input value is determined according to the pattern (PATTERN table) among the sections divided into N equal parts, and the current vehicle speed calculation result is compared in the shift pattern (Fig. 2), the proportional allocation for each section is performed. It is possible to determine whether the shift is performed by directly comparing the shift stages according to the throttle opening degree without calculating the result of. The shift pattern at this time is shown in FIG.

다음, 이와 같은 제어 후에 출력되는 변속제어유닛의 제어신호는 솔레노이드 밸브(5)를 제어하여 변속이 이루어진다.Next, the control signal of the shift control unit output after such control is shifted by controlling the solenoid valve (5).

이상에서와 같이, 이 발명의 실시예에서, 목표 변속단을 결정하는 방법을 단축함으로써 이에 따른 실시간 제어가 가능하게 되어, 변속 패턴으로부터 차기 변속단 결정 처리시간을 빠르게 할 수 있고, 타 제어기간 통합 제어에도 적용성이 높은 경차용 자동변속기 변속단 제어장치를 제공할 수 있다.As described above, in the embodiment of the present invention, by shortening the method for determining the target shift stage, real-time control is possible accordingly, thereby speeding up the next shift stage determination processing time from the shift pattern, and integrating other control periods. It is possible to provide an automatic transmission shift control device for a light vehicle which is highly applicable to the control.
