Abstract
무단 변속기(4)는, 변속비를 무단계로 변경할 수 있는 배리에이터(20)와, 배리에이터(20)에 대해 직렬로 설치되는 부변속 기구(30)를 구비한다. 변속기 컨트롤러(12)는, 차량의 운전 상태에 기초하여, 그 운전 상태에서 달성해야 할 배리에이터(20) 및 부변속 기구(30)의 전체의 변속비인 도달 스루 변속비를 설정하고, 이것에 기초하여 배리에이터(20) 및 부변속 기구(30)를 제어하지만, 부변속 기구(30)의 변속이 금지되어 있을 때에는, 도달 스루 변속비를 배리에이터(20)의 변속만으로 달성 가능한 변속비 범위로 제한한다.
