VEHICLE DRIVE APPARATUS CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/140731
Kind Code:
A1
Abstract:
When in step S1 an abnormality determination is made indicating there is a slip failure in which a forward clutch (C1), a backward brake (B1), or a belt-type continuously variable transmission (18) is in a slip state, or a complete disengagement failure in which the forward clutch (C1) or the backward brake (B1) is in a completely disengaged state, it is determined in step S2 whether an input/output rotation speed difference (δN) of a torque converter (14) is equal to or more than a predetermined slip determination value (δNs). If δN ≥ δNs, it is determined in step S3 that there is the slip failure. If δN <δNs, it is determined in step S5 that there is the complete disengagement failure. Thus, subsequent failsafe can be implemented individually and appropriately in step S4 or S6, so that a decrease in limp-home performance due to excessive failsafe can be prevented.
