CONTROL DEVICE FOR HYBRID VEHICLE

The object of the present invention is to improve the vehicle behavior response to accelerator operation when the second clutch is in slip engagement 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 CL2 slip transition control section (step S512 to step S515) configured to control a transition of the second clutch (5) to slip engagement when an engine start control is begun based on a mode transition request resulting from an accelerator depression operation, by increasing the torque transmission capacity of the second clutch (5) according to a prescribed slope after dropping the torque transmission capacity of the second clutch (5) to a value smaller than a target drive force.
