Abstract
A hybrid vehicle control device includes an engine start control section that begins an engine start control when a mode transition request to change to a hybrid vehicle mode occurs due to an accelerator operation while traveling in an electric vehicle mode in which a first clutch is opened. The engine start control section begins engagement of the first clutch after slip engagement of a second clutch is determined and starting the engine using a motor as a starter motor. A negative slip detecting/predicting section detects/predicts if a slip polarity of the second clutch has transitioned from positive slip to negative slip after the engine start control has begun and before the engine has started. A forced backup start control section starts the engine with the second clutch in a fully engaged state when a transition of the second clutch to negative slip has been detected or predicted.
