Abstract

본 발명의 목적은 스티어링시에 발생하는 엔진 회전수의 일시적인 떨어짐을 방지하는 것이다.An object of the present invention is to prevent a temporary drop in engine speed which occurs during steering.

어시스트 유압의 상승에 따라서 아이들 회전수가 저하하는 어시스트 유압의 급증시를 판정하는 수단(61)과, 어시스트 유압의 급증시에 목표 아이들 회전수를 유지하도록 부하 조정 밸브(59)를 거쳐서 어시스트 유압을 저하시키는 제어 수단(62)을 구비한다.The assist hydraulic pressure is lowered through the means 61 for determining the sudden increase in assist hydraulic pressure at which the idle rotational speed decreases as the assist hydraulic pressure rises, and the load adjustment valve 59 so as to maintain the target idle rotational speed when the assist hydraulic pressure increases. The control means 62 is provided.
