상기 변속기 제어장치(10)의 제어동작을 도 2의 플로우 차트를 참고로 상세히 설명하면 다음과 같다.The control operation of the transmission control device 10 will be described in detail with reference to the flowchart of FIG.

차량 주행 중에 사운드 모드 선택 스위치가 온(ON) 되는지를 검출하여 저소음 모드 동작을 수행할 것인지를 결정한다. 사운드 모드 선택 스위치가 온(ON) 되면, 다음 단계에서 음향 감지센서 SS로부터 차 실내의 소음을 검출한다.It is determined whether or not the sound mode selection switch is turned on while the vehicle is running, thereby determining whether to perform the low noise mode operation. When the sound mode selection switch is turned on, the noise of the vehicle interior is detected from the sound sensor SS in the next step.

검출된 소음 레벨이 소정의 기준치 보다 큰 지를 판단하고, 차 실내의 소음이 기준치 보다 크다면 저소음 주행에 대응한 변속패턴을 결정한다.Determines whether the detected noise level is greater than a predetermined reference value, and determines the shift pattern corresponding to the low-noise running if the noise in the passenger compartment is greater than the reference value.

저소음 변속패턴은 시험에 의해 고정된 별도의 변속 패턴으로 설정되고, 전자제어장치(10)는 저소음 변속패턴에 따라 유압제어기구(20)를 동작시키기 위해 출력단에 연결된 변속제어 솔레노이드 밸브 SCSV-A 및 SCSV-B에 전기적 출력신호를 공급한다.The speed control solenoid valve SCSV-A connected to the output stage for operating the hydraulic control mechanism 20 in accordance with the low noise shift pattern, and the speed change control solenoid valve SCSV- Supply an electrical output signal to SCSV-B.

저소음 모드로 변속기의 동작이 전환되면 다시 차내의 소음 레벨이 소정의 기준치 보다 큰 지를 판단한다. 차 실내의 소음이 기준치 보다 크다면 엔진 흡기관의 드로틀밸브 개도량을 줄이는 등의 동작을 수행하여 엔진 토오크를 저감시키고, 이로써 저소음 주행이 가능하도록 만든다.When the operation of the transmission is switched to the low noise mode, it is determined whether the noise level in the vehicle is greater than a predetermined reference value. If the noise level in the passenger compartment is higher than the reference value, the engine torque is reduced by reducing the amount of throttle valve opening of the engine, thereby enabling low noise traveling.

이상 설명한 바와 같이, 본 발명에 의하면 자동변속기시스템에서 변속 패턴에 저소음 모드를 추가하여 운전자가 저소음 주행을 원할 때 이에 적합한 변속단 구동으로 저소음 주행이 가능하게 됨으로써 운전자의 의지를 최대한 반영할 수 있는 장점이 있다.As described above, according to the present invention, when the driver desires low noise driving by adding a low noise mode to the shift pattern in the automatic transmission system, it is possible to carry out low noise driving by suitable speed change step driving, .
