이 발명은 자동 변속기의 엔진 속도에 따른 변속 제어 방법에 관한 것으로서, 더욱 상세하게 말하자면 엔진 시동시 엔진의 열을 빨리 높이기 위해 엔진 속도를 크게하는데 이때, 크리프(CREEP)의 힘도 세어지는 것을 운전 조건에 알맞게 조절하는 자동 변속기의 엔진 속도에 따른 변속 제어 방법에 관한 것이다.The present invention relates to a shift control method according to the engine speed of an automatic transmission. More specifically, the engine speed is increased in order to increase the heat of the engine at the start of the engine. In this case, the force of the creep is also increased. It relates to a shift control method according to the engine speed of the automatic transmission to be adjusted accordingly.

종래에는 엔진의 온도가 낮으면, 엔진의 온도 보정을 위해서 엔진 속도를 높이기 때문에 토크 컨버터(TORQUE CONVERTOR)를 빨리 회전시킨다.Conventionally, when the temperature of the engine is low, the torque converter is rotated quickly because the engine speed is increased to correct the temperature of the engine.

그러나, 상기한 종래의 기술은, 상기의 경우 차가 주행코자 하는 힘도 증가하여서, 운전자가 브레이크 밟아야 하는 경우 힘이 많이 들어야 하며, 밀고나가는 힘이 세기 때문에 안전 사고에 문제점이 있다.However, in the above-described conventional technology, the force that the car wants to drive also increases in the above case, so that the driver must brake a lot, and there is a problem in the safety accident because the pushing force is high.

따라서, 이 발명의 목적은 상기한 종래의 문제점을 해결하기 위한 것으로서, 엔진 회전수 및 자동 변속기용 오일(AUTOMATIC TRANSMISSION FLUID, 이하 ATF라함)의 온도를 측정하고 이를 토대로 듀티(DUTY)값을 조절하여 크리프의 힘을 줄이는 자동 변속기의 엔진속도에 따른 변속 제어 방법을 제공하기 위한 것이다.Accordingly, an object of the present invention is to solve the above-described problems, and by measuring the engine speed and the temperature of the automatic transmission oil (AUTF), the duty value is adjusted based on this. An object of the present invention is to provide a shift control method according to an engine speed of an automatic transmission that reduces creep force.

상기한 목적을 달성하기 위한 수단으로써 이 발명의 구성은, 자동 변속기 차량에서 정차시에도 앞으로 나가려는 크리프 조건인지를판단하는 단계와; 상기 크리프 조건시에 엔진 속도가 1000rpm이 넘는지 판단하는 단계와; 자동 변속기용 기름(AFT)의 온도가 20℃보다 낮은지를 판단하는 단계와; 상기의 두 조건중에 속한다면 듀티율을 50%로 하는 단계와; 상기의 두 조건에 속하지 않으면 듀티율를 85%로 하는 단계로 이루어진다.As a means for achieving the above object, the configuration of the present invention comprises the steps of: determining whether it is a creep condition to go forward even when stopped in the automatic transmission vehicle; Determining whether an engine speed exceeds 1000 rpm during the creep condition; Determining whether the temperature of the automatic transmission oil (AFT) is lower than 20 ° C; Setting a duty rate of 50% if one of the above two conditions is met; If the conditions do not belong to the above two conditions, the duty rate is 85%.

이하, 이 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 이 발명을 용이하게 실시할 수 있는 가장 바람직한 실시예를 첨부된 도면을 참조로하여 상세히 설명한다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 제1도에 도시 되어 있는 바와 같이 이 발명의 실시예에 따른 자동 변속기의 엔진 속도에 따른 변속 제어 방법의 구성은, 자동 변속기 차량에서 정차시에도 앞으로 나가려는 크리프 조건인지를 판단하는 단계(S20)와; 상기 크리프 조건시에 엔진 속도가 1000rpm이 넘는지 판단하는 단계(530)와; 자동 변속기용 기름(ATF)의 온도가 20℃보다 낮은지를 판단하는 단계(S40)와; 상기의 두 조건중에 속한다면 듀티율을 50%로 하는 단계(S50)와; 상기의 두 조건에 속하지 않으면 듀티율을 85%로 하는 단계(S60)로 이루어진다.As shown in the accompanying FIG. 1, the configuration of the shift control method according to the engine speed of the automatic transmission according to the embodiment of the present invention includes determining whether it is a creep condition to be moved forward even when the automatic transmission vehicle stops ( S20); Determining (530) whether an engine speed exceeds 1000 rpm during the creep condition; Determining whether the temperature of the automatic transmission oil (ATF) is lower than 20 ° C. (S40); If the duty ratio falls within the two conditions (S50); If the conditions do not belong to the above two conditions, the duty ratio is 85%.

상기한 구성에 의한, 이 발명의 실시예에 따른 자동 변속기의 엔진 속도에 따른 변속 제어 방법작용은 다음과 같다.The shift control method action according to the engine speed of the automatic transmission according to the embodiment of the present invention by the above configuration is as follows.

자동 변속기 차량에서 정차시에 D레인지에 위치할 때, 운전자가 악셀러레이터(ACCELERATOR)를 밟지 않아도 토크 컨버터(TORQUE CONVERTOR)를 매개로 하여, 완전히 동력이 끓어지지 않아 서서히 진행하는 상태의 크리프의 조건인지를 판단을 하고(S20), 상기 크리프 조건이 되면 엔진 속도를 측정한다.When the vehicle is located in the D-range when the vehicle is stopped in the automatic transmission, the condition of the creep in which the power does not boil completely due to the torque converter, even though the driver does not step on the accelerator. The determination is made (S20), and the engine speed is measured when the creep condition is reached.

엔진 속도가 1000rpm이 넘는지 판단해서(S30), 제2도의 도표와 같이 그 이상을 넘으면 킥 다운 브레이크(KICK DOWN BRAKE)의 공급 압력에 관한 듀티(DUTY)율을 50%로 내린다(S150).It is judged whether the engine speed exceeds 1000 rpm (S30), and if it exceeds more as shown in the diagram of FIG. 2, the duty ratio regarding the supply pressure of the kick-down brake is reduced to 50% (S150).

듀티율을 0 혹은 100을 출력하지 않는 것은 변속시 쇼크(SHOK)를 방지와 응답의 향상 때문이다.The reason for not outputting a duty ratio of 0 or 100 is to prevent shock during shifting and to improve response.

또한, 엔진 속도가 보통 700, 800rpm 정도의 정상이면, 자동 변속기용 기름(ATF)의 온도를 측정한다.In addition, if the engine speed is normally about 700 or 800 rpm, the temperature of the automatic transmission oil (ATF) is measured.

자동 변속기용 기름(ATF)의 온도가 20℃보다 낮다면 (S40), 상기와 같이 듀티율을 50%로 내린다 (S50).If the temperature of the automatic transmission oil (ATF) is lower than 20 ℃ (S40), the duty ratio is reduced to 50% as described above (S50).

따라서, 상기의 두 조건중에 속한다면 듀티율을 50%로 하고(S50),상기의 두 조건에 속하지 않으면 듀티율을 85%로 한다(S60).Therefore, the duty rate is set to 50% if it falls within the two conditions (S50), and if it does not fall under the two conditions above, the duty rate is set to 85% (S60).

이상에서와 같이 이 발명의 실시예에서, 상기 듀티율을 조정하므로서, 브레이크(BRAKE)의 압력을 줄여 운전자의 편의성을 도모하고, 이로 인한 사고를 예방할 수 있는 효과를 가진 자동 변속기의 엔진 속도에 따른 변속 제어 방법을 제공할 수 있다.As described above, in the embodiment of the present invention, by adjusting the duty ratio, reducing the pressure of the brake (BRAKE) to facilitate the driver's convenience, the shift according to the engine speed of the automatic transmission having the effect of preventing accidents caused by this A control method can be provided.
