Abstract

전자제어장치가 변속요구조건에 따라서 변속유형(Fl,F2,F3)을 결정하고 이론상의 주행점과 이론상의 주행점이 변속유형에 따르는 실제주행점과 비교하여 제1 또는 제2변속영역을 선택하는 자동변속기의 제어방법을 제안한다.

Description

자동변속기의 제어방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 변속유형의 특성장.
제2도는 공차대를 가진 변속유형의 특성장.

Claims (3)

  1. 그의 변속상태와 압력변화가 전자제어장치의 전자기식 서보요소에 의하여 결정되는 크러치를 가진 자동변속기의 제어방법에 있어서, 전자제어장치는 입력치에 의하여 운전자의 고단 또는 저단변속을 위한 변속요구조건을 식별함으로서 1단을 올리는 고단변속이나 또는 1단을 낮추는 저단변속 또는 1단 이상을 낮추는 저단변속에 해당되는 변속유형을 결정하며 이때 운전자가 원하는 출력을 나타내는 특성치(E2)와 내연기관의 회전수나 또는 자동변속기의 종동회전수(E1)로부터 실제 주행점이 결정되고 하나의 특성장에 의하여 제1 또는 제2변속영역이 선택되는 바 이때 특성장은 변속유형(F1,F2,F3)에 대한 이론상 주행점의 상관관계를 포함한다는 것을 특징으로 하는 방법.
  2. 제1항에 있어서, 동일한 변속유형(F1,F2,F3)의 이론상 주행점의 상관관계는 공차대(T1 내지 T6)로 둘러싸여 있는 것을 특징으로 하는 방법.
  3. 제2항에 있어서, 이론상 주행점에 대하여 실제주행점이 바뀔 때 변속영역은 우선 공차대를 떠남으로서 이루어지는 것을 특징으로 하는 방법.
    ※ 참고사항:최초출원 내용에 의하여 공개하는 것임.
