Abstract

자동 변속장치의 변속동작이 이루어지는 동안 엔진의 회전수를 설정값으로 고정시켜 엔진 회전수의 변화로 인한 변속 토크의 변동이 발생하지 않도록 하기 위한 자동 변속장치의 변속감 향상장치 및 그 방법을 제공하기 위하여, 엔진의 회전수를 감지하여 해당하는 신호를 출력하는 엔진 회전수 감지수단(11)과; 스로틀 밸브의 개도정도를 감지하여 해당하는 신호를 출력하는 스로틀 밸브 개도상태 감지수단(14)과; 자동 변속장치의 변속동작의 시작시점을 판단하여, 변속동작이 시작되고 스로틀 밸브의 개도변화가 없을 경우에 변속 직전의 엔진 회전수로 엔진의 회전수를 고정한 후 변속동작을 실행할 수 있는 제어신호를 자동 변속장치(3)로 출력하는 변속 제어수단(2)으로 이루어진다.In order to provide a speed change improving device and a method of the automatic transmission for fixing the engine speed to a set value during the shift operation of the automatic transmission so that the shift torque does not occur due to the change of the engine speed. Engine speed detection means 11 for detecting the rotational speed of the engine and outputs a corresponding signal; A throttle valve opening state detecting means 14 for detecting an opening degree of the throttle valve and outputting a corresponding signal; Determines the starting point of the shifting operation of the automatic transmission, and when the shifting operation is started and there is no change in the opening degree of the throttle valve, a control signal capable of executing the shifting operation after fixing the engine speed to the engine speed immediately before the shifting is performed. It consists of the shift control means 2 which outputs to the automatic transmission 3.
