An interlock determination device comprises 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.
互锁判定装置具备:判定在自动变速器(AT)中是否发生了互锁的互锁判定部(72);决定许可或禁止该判定的执行的判定执行判断处理部(71)。判定执行判断处理部(71)在为了基于从“EV模式”向“HEV模式”的模式转换请求起动发动机(Eng)而将自动变速器(AT)的第二离合器(CL2)设为滑动联接状态时,从第二离合器(CL2)的滑动开始至确认滑动收敛为止,禁止互锁的判定执行。
