CONTROL DEVICE FOR HYBRID VEHICLE

摘要

The object of the present invention is to prevent a shock from occurring when a slip polarity of a second clutch changes to negative slip after the engine start control has begun. The hybrid vehicle control device has an engine (1), a motor/generator (2), a first clutch (4), a second clutch (5), and an engine start control means ( FIG. 11 ). The first clutch (4) is disposed between the engine (1) and the motor/generator (2). The second clutch (5) is disposed between the motor/generator (2) and tires (7, 7). The engine start control means ( FIG. 11 ) has a negative slip detecting/predicting section (step S511) configured to detect or predict if a slip polarity of the second clutch (5) has transitioned from positive slip to negative slip after the engine start control has begun, and a forced backup start control section (step S514 to step S519) configured to start the engine with the second clutch (5) in a fully engaged state when a transition of the second clutch (5) to negative slip has been detected or predicted.
