Control device for a four-bar linkage-type continuously variable transmission

摘要

PROBLEM TO BE SOLVED: To provide a control device for a continuously variable transmission capable of rapidly reducing a radius of rotation motion on an input shaft side when there is a possibility that a traveling drive source is stopped by rapid deceleration.;SOLUTION: A control device 40 for a continuously variable transmission 1 includes a no-load radius acquiring part 43 for acquiring a no-load eccentric amount nlr in accordance with engine speed detected by a first engine speed detecting part 31 and a second engine speed detecting part 32, a radius control part 45 for executing radius reduction processing when there is a possibility that operation of a traveling drive source 27 is stopped, and an increase processing permitting part 46 for permitting execution of increase processing by a driving force increase part 44 when the radius acquired by a current radius acquiring part 42 is equal to or lower than the no-load radius when there is a possibility that operation of the traveling drive source 27 is stopped, and preventing execution of increase processing until the acquired radius becomes equal to or less than the no-load radius when the acquired radius is larger than the no-load radius.;COPYRIGHT: (C)2014,JPO&INPIT
