Description
본 고안은 차량에 관한 것으로, 특히 콜드 스타트(COLD START)후 가속시 발생되는 E/M을 줄일 수 있도록 하는 차량의 자동변속기 제어장치에 관한 것이다.The present invention relates to a vehicle, and more particularly, to an automatic transmission control device for a vehicle to reduce the E / M generated during acceleration after a cold start (COLD START).
일반적으로 모드에 따라 차량이 가속할 때 첫번째 가속에서 오토 트랜스미션은 4단까지 변속되는 것을 알 수 있다.In general, depending on the mode, when the vehicle accelerates, it can be seen that the auto transmission shifts up to four gears at the first acceleration.
엔진의 부하신호를 보면 변속이 될 때마다 동기하여 급격한 변화를 보이고 있다.Looking at the load signal of the engine, it shows a sudden change in synchronism every shift.
이는 첫번째 가속시 E/M량이 대단히 많으며 이 E/M 량은 엔진이 부하에 비례하는 것을 알 수 있다.This shows that the amount of E / M at the first acceleration is very high and the amount of E / M is proportional to the load of the engine.
즉, 엔진의 부하를 줄여주거나 또한 급격한 변화가 없으면 E/M배출량은 줄어든다.In other words, if the engine load is reduced or there is no sudden change, the E / M emissions are reduced.
종래 오토 트랜스미션 오일 온도를 감지하는 이유는 댐퍼 클러치를 작동하는 영역 제한을 두기 위함이며, 오일 온도에 상관없이 시프트 스케줄에 따라 업 시프트가 이루어지고 있다.The reason for detecting the conventional automatic transmission oil temperature is to limit the area in which the damper clutch is operated, and the upshift is performed according to the shift schedule regardless of the oil temperature.
본 고안 차량의 자동변속기 제어장치는 이와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 북미 강화 E/M규제에 대응하여 콜드 스타트후 가속시 발생되는 E/M을 감소시킬 수 있는 차량의 자동변속기 제어장치를 제공하는데 그 목적이 있다.The automatic transmission control device of the present invention is devised to solve such a conventional problem, and the automatic transmission of the vehicle that can reduce the E / M generated during the acceleration after cold start in response to the North American tightened E / M regulations Its purpose is to provide a control device.

이와 같은 목적을 달성하기 위한 본 고안은 트로틀 위치를 감지하는 TPS와, 오토트랜스미션의 오일 온도를 감지하는 온도감지센서와, 차속을 감지하는 차속감지센서와, 상기 각 센서들에 의해 감지된 데이타를 입력받아 변속기의 변속을 제어하는 TCU로 구성함을 특징으로 한다.The present invention for achieving the above object is a TPS for detecting the position of the throttle, a temperature sensor for detecting the oil temperature of the automatic transmission, a vehicle speed sensor for detecting the vehicle speed, and the data sensed by the sensors It is characterized by consisting of a TCU to control the transmission of the transmission received.
이하, 본 고안의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention in detail as follows.
도 2는 본 고안의 구성도로, 트로틀 위치를 감지하는 TPS(1)와, 오토트랜스미션의 오일 온도를 감지하는 온도감지센서(2)와, 차속을 감지하는 차속감지센서(3)와, 상기 각 센서(1-3)들에 의해 감지된 데이타를 입력받아 변속기(5)의 변속을 제어하는 TCU(4)로 구성된 것이다.2 is a configuration diagram of the present invention, the TPS (1) for detecting the position of the throttle, the temperature sensor (2) for detecting the oil temperature of the automatic transmission, the vehicle speed sensor (3) for detecting the vehicle speed, and each of the It is composed of a TCU (4) for controlling the shift of the transmission (5) by receiving the data sensed by the sensors (1-3).
이와 같이 구성된 본 고안은 현재의 TCU시스템을 그대로 사용하며, 먼저 온도감지센서(2)로부터 오토 트랜스미션 오일의 온도를 감지하고, TCU(4)에서는 이를 인식하게 된다.The present invention configured as described above uses the current TCU system as it is, and first detects the temperature of the auto transmission oil from the temperature sensor 2, the TCU (4) recognizes this.
만일 오일의 온도가 낮은 경우에는 1→2단, 2→3단으로 시프트를 단계적으로 딜레이(DELAY)시킨다.If the temperature of the oil is low, the delay is delayed in steps 1 → 2 and 2 → 3.
즉, 도 3에 도시된 바와 같이 오토 트랜스미션의 오일 온도가 기준치 이하일 때에는 시프트 스케쥴을 변경한다.That is, as shown in FIG. 3, the shift schedule is changed when the oil temperature of the auto transmission is lower than the reference value.
따라서, 상기와 같이 기어의 시프트를 변경시키면, 엔진의 부하가 떨어져 E/M을 감소시킬 수 있는 것이다.Therefore, if the shift of the gear is changed as described above, the load of the engine falls and the E / M can be reduced.
이상과 같은 본 고안 차량의 자동변속기 제어장치에 의하며, 대부분의 E/M이 첫번째 가속시 대부분 배출되므로 업 시프트를 늦게 하여 엔진의 부하를 저감시키고, 이에 따라 E/M을 저감할 수 있는 것이다.According to the automatic transmission control device of the present invention as described above, since most of the E / M is discharged during the first acceleration, the up-shift is delayed to reduce the load of the engine, thereby reducing the E / M.
