More Information
Summary:The present invention comprises: a step of checking a current shifting range among a plurality of shifting ranges; a step of setting a tither frequency of a pressure control solenoid valve of a transmission hydraulic circuit as a predetermined first frequency; and a step of setting the thither frequency of the pressure control solenoid valve as a predetermined second frequency when the current shifting range is the shifting range except the first range. 본 발명은 다수의 변속레인지들 중, 현재 변속레인지를 확인하는 단계; 상기 현재 변속레인지가 소정의 제1레인지인 경우, 변속기 유압회로의 압력제어 솔레노이드밸브의 디더 주파수를 소정의 제1주파수로 설정하는 단계; 상기 현재 변속레인지가 상기 제1레인지 이외의 변속레인지인 경우, 상기 압력제어 솔레노이드밸브의 디더 주파수를 소정의 제2주파수로 설정하는 단계를 포함하여 구성된다.
