Document Type and Number:
WIPO Patent Application WO/2019/031177
Kind Code:
A1
Abstract:
An interlock determination device comprising an interlock assessment unit (72) for assessing whether an interlock has occurred in an automatic transmission (AT); and an assessment execution determination processing unit (71) for determining whether to allow or prohibit the execution of this assessment. When a second clutch (CL2) of the automatic transmission (AT) is placed in a slip-engaged state for starting the engine (Eng) on the basis of a mode transition request for transitioning from an "EV mode" to an "HEV mode", the assessment execution determination processing unit (71) prohibits the execution of the interlock assessment from the beginning of the slipping of the second clutch (CL2) until slip convergence has been confirmed.
